The roars came from the sky, and the thick clouds made people on the ground unable to see the planes on the clouds, but the huge buzzing sound that shocked the sky made people feel a sense of fear of ruining the world.

Above the clouds, at a height of ten thousand meters, twenty-four big white crane strategic bombers from the Tang Empire Air Force appeared over Wugang.

"Confirmed that you have arrived in Wugang and start the bombing plan!"

In the position of the co-pilot of the chief aircraft, a school official had just determined through maps and aerial photos that the area below was Wugang, the most important base of the Japanese Navy.

"The clouds will have a certain impact on my high-altitude bomb aiming!"

"It's okay, let's circle for a while, the Northeast wind of the sixth level will soon blow away the clouds!"

"The Japanese may be prepared for evacuation and air defense, and our air strike effect may be reduced."

The captain and the deputy captain exchanged opinions and discussed countermeasures, but in the end, the more conservative captain made a decision, and everything was based on the air strike mission target and his own maximum security.

"If we lower the altitude and enter below the clouds, we may be attacked by the Japanese intensive anti-aircraft artillery and cause losses. You must understand that our aircraft are different from the past. They are related to the core secrets of the country. Once shot down, the core secrets may fall into the hands of the enemy. If the Japanese also study long-range strategic bombers and high-precision bomb drop sights, it will be a disaster for the Tang Empire, because our land area is too small and cannot withstand large-scale bombing."

Although the Dabai Crane strategic bomber is a strategic bomber technology that the aviation community around the world wants to obtain, the technology that can accurately drop bombs at a height of 10,000 meters is the core of the core, which makes all the parties even more crazy.

Before the bombers of the bombers of the strategic aviation fleet received precise bombing equipment training, the Tang Empire Air Force must swear to strictly protect the technical information of the secret equipment they came into contact with, and even protect the secrets at the cost of their lives when necessary. This special equipment is a high-altitude bombing sight invented by Norton, a native of the Tang Dynasty.

It is not easy to accurately drop a bomb from a high air to a point-like target on the ground, especially in the 1930s, experts from all over the world racked their brains but failed to develop it, which put the Tang Empire ahead. If the bomb dropped by the aircraft was doing purely ideal free fall movement, the bounce point might not be very troublesome, but the key is that the aircraft is flying in the air, and the wind speed, wind direction, and the aerodynamic characteristics of the bomb will have an impact on the accuracy of the bomb drop. The most troublesome thing is that the most critical earth speed in the bomb drop, or the flight speed of the aircraft relative to the ground, is difficult to directly measure, which causes a considerable deviation in the bomb drop.

Carl Norton, a Dutch-born engineer who worked in the Tang Empire National Laboratory, made a bold attempt on this issue. He designed a new type of bombing sight for the Tang Empire Naval Aviation Corps - the Navy needed to carry out precise bombing of point-shaped targets on the sea. But later the Tang Army Air Force also adopted this novel-designed bombing sight and improved it, and finally applied it to the Dabai Crane strategic bomber.

A complete Norton bombing sight includes two main components, a stabilizer and a sight. The stabilizer is actually a working platform that uses a gyroscope to maintain level. Its function is to provide a stable reference plane for the sight. The stabilizer often works in conjunction with the bomber's autopilot. This can directly control the aircraft to maintain horizontal flight. The sight Tang Jun uses a combination of a starring mechanical sight and a front-facing optical gyroscope sight. It can accurately calculate the bounce point at an altitude of 100 meters within the error range. The best result during the test is 13 meters, which are the effects obtained by the high accuracy of the optical sight. But the disadvantage is that it will be affected by the clouds, which is also a flaw of the optical sight.

"I understand the captain's concerns, so let's do it according to the captain's wishes. Anyway, our target is the Japanese naval shipyard and two Yamato-class battleships in Wugang. They can't escape after a while."

"Maybe we can fly elsewhere first, and then fly back after a while. Maybe the Japanese thought we were just passing by, and their air defense alarm was quickly lifted."

The captain suddenly made a new suggestion. The deputy captain's eyes lit up and he nodded immediately to agree. So the two discussed and decided that twenty-four big white crane strategic bombers quickly flew out of the sky above Wugang and disappeared into the sky.

There was panic on the ground of Wugang. When the alarm sounded just now, tens of thousands of Japanese workers were scared and fled in all directions. All the Japanese air defense forces around them were in place, and guns were loaded to prepare for air defense operations.

All the Japanese troops stared at the sky as if they were facing a great enemy, but as the roar went away, they all showed shock.

"What's going on? Didn't you come to blow us up?"

"The sound has gone far away. It seems that it is heading towards Hirado. Could it be that it is going to attack Hirado in air?"

The Japanese commander of Wugang was confused, but it was a good thing that the enemy planes went far away and did not attack Wugang.

Not long after, Wugang, who could not hear the buzzing sound, lifted the air defense alarm, and all Japanese workers returned to the factory to work, especially the shipyard. The Yamato and Wuzang ships had reached the final stage. The Japanese Navy urgently needed them to serve as soon as possible in order to reverse the situation, so the workers quickly returned to the second ship to work.

At this moment, the clouds in the sky had been blown away from the sky above Wugang by a level 6 wind, and the sky was clear. Such a good weather should have a great mood, but soon the Japanese in Wugang found that rows of bright silver light spots were approaching quickly in the sky, and soon a buzzing sound that scared them was coming.

"Yes - it's the enemy plane! He - they are back!"

In the air defense post, the Japanese sentry had discovered the Tang army bomber group through a telescope. This time, it was clear that the behemoth was much larger than the mid-range heavy bomber they were familiar with before, that is, the Big White Crane bomber that was rumored to have destroyed many Spanish cities.

After hesitating for a few seconds, the alarm was sounded again.

Many Japanese people were slow to go back to their jobs this time. Even many Japanese air defense soldiers were slow to go for a while. They didn't understand why the alarm sounded again, so they ran to their posts reluctantly.

"Damn it. Why are you back?"

The Japanese commander's head suddenly grew bigger. He thought Wugang was safe, but it was obviously impossible at this moment.

"Air defense combat, hurry!"

The order was issued, and thousands of anti-aircraft anti-aircraft guns around Wugang opened fire violently, and countless shells shot into the sky, causing the whole body to tremble.

Bang! Bang bang!

The sky was full of explosions. The high-altitude blasting bombs fired by Japanese anti-aircraft artillery were very powerful and relied on the kinetic energy of shell debris to attack the aircraft.

The twenty-four large white crane strategic bombers of the Tang army were still flying calmly, like the day cranes spreading their wings. The snow-white fuselage reflected the light of the sun, which looked very sacred.

The Japanese anti-aircraft shells could not hit a height of 10,000 meters, and exploded at most at a height of 1,000 meters, producing black smoke and clouds.

The dense air defense firepower network looked very powerful. The Japanese commander laughed with satisfaction as he saw the Tang army plane not daring to descend.

"Our Japanese Empire has endured humiliation over the years. In order to prevent the Tang army bombers from causing fatal damage to us again, we spent a lot of money to tighten our belts to buy such powerful anti-aircraft artillery. Now it seems that our efforts have been rewarded, and the Tang army bombers dare not come down at all."

The Japanese on the ground were very happy, and they cheered for the powerful Japanese air defense forces. However, the next moment, someone suddenly screamed.

"Look, Tang Jun opened the bomb drop hatch door of the bomber!"

"Oh my God. Are they going to drop bombs at a height of ten thousand meters?"

"They must be afraid of being shot down by our powerful artillery fire, so they can't wait to drop the bomb and return."

"Don't panic. If you drop bombs at that height, you won't be able to blow us up at all. Their aviation bombs will explode in mid-air."

The ability of the Tang army's Great White Crane strategic bomber to drop bombs at an altitude of 10,000 meters is unknown to the Japanese army. The Tang army has only secretly tested it on the local area. On the Spanish battlefield, because Spain does not have a strong air force, the Tang army does not need to drop bombs at an altitude of 10,000 meters, and the outside world does not know this secret.

"Target locked, ready to drop bombs!"

The bomb dropper used the precise bomb drop sight to accurately lock the target to be bombed, and then pressed the bomb drop button.

…Yi!…Yi!………

The aviation bombs that had already installed the delay fuse slid out of the bomb bay in turn, making a sharp whistle and landed at the Wugang Naval Shipyard.

Aviation bombs weighing 500 kilograms fell from a height of 10,000 meters, hit at an extremely terrifying speed under gravity. The speed at which the landing instantly landed exceeded 500 meters per second. The dock platform of two meters thick poured with reinforced concrete in Wugang Shipyard was instantly penetrated. Just like a magnitude eight earthquake, all buildings within a radius of hundreds of meters collapsed in an instant, and everyone was knocked to the ground.

With a loud bang, the boat platform more than two meters thick was blown up, steel broke, earth and rocks flew around, and smoke and dust filled the sky. The explosion shock wave swept through everything, and everyone within hundreds of meters around was blown away, and countless broken and heart-wrenching screams were heard.

Scream...boom!

A destroyer under construction in the dock moved horizontally from the base of the ship platform due to a severe earthquake and slammed to one side. Hundreds of workers who had no time to escape were all smashed into the dust of the ruins.

Bang! Bang! Bang! Bang!

Aerial bombs fell one after another, making a roar of explosions that destroyed the world. The entire Wugang Naval Shipyard was instantly trapped in the vast sea of ​​fire and dust.

The Yamato battleship and the Wuzang battleship are the objects of special care. Most aviation bombs bombs hit the hulls of these two super battleships. The aviation bombs that came down from a height of 10,000 meters carried terrifying gravity acceleration and penetrated the horizontal defensive armor as high as 230 mm thick. Aviation bombs of 500 kilograms exploded inside the giant ship, causing fatal damage to the super giant ship that took many years to be completed.

Yamato was much worse than Wuzang. In less than a minute, it suffered eighteen 500-kilogram aviation bombs in succession. The giant main gun barrels, which were more than ten meters long and weighed hundreds of tons, were twisted into a twist shape. The entire superstructure was razed to the ground, and huge pits of several meters in diameter were everywhere on the deck. Fire was burning, thick smoke was rolling across the sky and the sun. The horizontal deck of the entire battleship was completely destroyed. The steel armor of hundreds of millimeters thick around was rolled up, like leather shoes with mouths on all sides.

Several aviation bombs landed on the surrounding water surface, causing huge waves hundreds of meters high, causing the Yamato, which had lost its lateral structural balance, to plummet. The sea water flooded and tens of thousands of tons of sea water poured in just a few minutes, causing the Yamato to finally dump, and half of the hull was submerged into the sea water and fell into the mud.

The Wuzang was only eleven aviation bombs, and the superstructures were all destroyed by explosion shock waves. The hull was blown up one by one, and the entire ship was ignited with fire. Although it was severely damaged, it was just fortunately not overturned.

The Tang army dropped all high-penetrating aviation bombs in the first few minutes, and the purpose had been achieved, which severely damaged the Yamato and Wuzang. Next, the Tang army's twenty-four major white crane strategic bombers dropped more than a dozen white phosphorus bombs.

The production volume of this white phosphorus bomb is not large, so each large white crane can carry dozens of them. Since the white phosphorus bomb itself requires it to be released in mid-air and is a weapon of mass destruction, the Tang army did not need to lower the altitude and directly dropped it at a height of 10,000 meters.

The white phosphorus bombs exploded in the air, blooming like fireworks. The fragments dragged the long white smoke tails and fell around the entire Wugang Naval Shipyard. Houses, ship platforms, gantry cranes, warships, personnel, and various stacked shipbuilding equipment and materials were immediately corroded and ignited. Tens of thousands of Japanese combatants and shipyard workers were killed by white phosphorus bombs to varying degrees. The body was burned through a hole in the mild body, and the severe ones were disabled and died. The extremely miserable scene made every Japanese who had experienced this disaster remember it deeply and lived in fearful memories all their lives.

Just as the Japanese Naval Shipyard of Wugang was air strike by the Tang Empire, the Yokosuka Shipyard in Tokyo Bay was also bombed by a large-scale bombing by the Tang army bomber group. The entire Yokosuka Shipyard was bombed like the Wugang Shipyard. What made the Japanese most distressed was that the two Yamato sister ships Shinno and Changlu were also severely damaged, with a damage rate of up to 55%. The Japanese army worked hard for four or five years and spent hundreds of billions of yen, but they were ruined by the Tang army.

What even more confusing the spirit of the Japanese army was that the air defense force they invested heavily to build failed to shoot down a Tang army bomber. Instead, tens of thousands of Japanese and shipyard workers were killed and injured, and the price could only be expressed in a tragic way.
