‘Dong!Dong!Dong!’

At Xiakou, there was a loud drum sound on the river surface. More than 600 warships were divided into red and green armies and fought on the river surface. The wind and waves were extremely strong, and the dense warships were undulating in the wind and waves, but the two navy troops were not affected at all. The battle was fierce, and arrows were like rain. Groups of soldiers flew into the enemy ship, wielding swords and spears to kill the enemy.

A large ship with a three thousand stone planted a red flag and rushed around the small boat group, constantly overturning the small boat, and the soldiers on the boat fell into the water one after another.

But if you look closely, you will find that under the big ship, dozens of water ghosts wearing black fish-skinned water have climbed onto the wall of the big ship, just like dozens of leeches. The water ghosts took off their skins from their backs and sprayed tinder oil on the walls of the ship.

This is a large-scale military exercise for the navy of Jiangxia. There are 20,000 navy soldiers and 600 warships participating in the war. This military exercise has been going on for two months, with nearly 30 exercises in total, and an average battle is fought every two days.

This is actually a practical training method, and there is no difference between it and real war. Training is very dangerous and cruel. Nearly a hundred people have been killed and injured in training, and dozens of warships have been hit and sunk.

After meeting with Zhou Yu, Liu Jing immediately turned north. At this time, his ship also appeared on the edge of the warship, quietly watching the huge military exercise.

"Qi Bingzhou Governor, that's the target ship!"

On the bow of the ship, Gan Ning pointed at an old ship about two thousand stones in the distance. There was a large blue flag on the ship and three sails on it, sailing rapidly westward. On the left and right sides, two thousand stone warships with red flags were chasing closely, and the two sides were about three hundred steps apart.

Liu Jing suddenly became interested and stared at the two Red Flag warships. This is a typical tactic of pursuing the opponent's logistics ships. If the logistics transport ship is single, two warships will chase each other.

Today, due to Liu Jing's arrival, this old ship of 2,000 stone will be sunk.

At this time, the warship on the left suddenly shot out a ball of fire, hitting the sail heavily. It was tinder and sticking to the sails. The sails suddenly burned rapidly. The two warships shot out fireballs at the same time, hitting the escaped logistics ships. The fire quickly spread on the ship and quickly swallowed the ship.

Liu Jing's expression became extremely serious. He was not surprised by tactics and fireballs, but because of the range. He knew very well that the fireball behind was shot with a stone cannon, and the range of the stone cannon on the river surface was only fifty steps, but he could see clearly today that it was clearly a hundred-step range. How could this be done?

He looked back at Gan Ning in confusion. Gan Ning seemed to know his doubts and explained with a smile: "This is the highlight of today's military exercise. Testing new stone cannons has been improved by Mr. Ma, and the range has been doubled, but the size is still the same as before."

"I see!"

Liu Jing laughed. It would be no surprise if it was Ma Jun. Since Ma Jun returned to Jiangxia half a year ago, Liu Jing fulfilled his promise and built a craftsmanship school in Xiakou, specializing in training high-level craftsmen. There were about 200 people, most of them young people in their twenties, most of whom were fortifications in the army.

Ma Jun served as the culprit of craftsmanship. He worked with his disciples to study various mechanical technologies every day, creating many major achievements, such as improving the keel water wheel, which is convenient to pedal and draw water, which can greatly improve the efficiency of water intake. It is especially suitable for dense water networks in the Jianghan Plain and Jiangdong area. In just half a year, the new keel water wheel has been spread to Dongwu.

For example, they invented a wheeled trencher. With the same twist, nine boulders can be emitted at the same time, and the range is increased by fifty steps, which increases the efficiency of war by nine times, which is extremely effective in defending the city.

"Where is Mr. Ma now?"

Gan Ning pointed to the chasing warship, "He is now on the warship on the right."

Liu Jing felt infinite expectation in his heart, and he immediately ordered: "Go and see!"

The big ship sailed and headed towards the distant river.

The target ship hit by the fireball is still burning, with its huge hull tilted and half of it entering the water. Even in a military exercise, this scene is particularly tragic, as if the end of life has brought a strong psychological impact to all the participating soldiers. This is also one of the purposes of the drill to prevent morale from collapsing.

Dozens of small boats searched around for thirty soldiers who had dived and escaped, "Finished!" With a surprise shout, the last soldier was discovered and rescued on the small boat. The small boat quickly left, and the sinking of the big ship would bring huge suction force, which would be a catastrophe for the surrounding small boats and people.

． ． ． ． ． ． ．

Liu Jing got on the warship, and Ma Jun, who was full of excitement, bowed forward and said slowly: "See... the governor of the state!"

Although he was still a little stuttering, it was much better than before. After receiving Zhang Ji's careful treatment, he had found a way to treat his stuttering, which was to deliberately slow down his speech. After nearly half a year of correction, he made great progress. More importantly, this progress made Ma Jun confident in himself.

"I heard that the sir has made a new stone cannon. Can I see it?"

"Just just improve, please do it!"

Ma Jun invited Liu Jing into the cabin. At the side of the bulkhead on the left, Liu Jing saw a new stone cannon. In fact, the shape was still the same as before, but the previous pull rod was gone, but turned into a winch and a two-meter-long copper rod. This slender copper rod made Liu Jing suddenly realize something. He remembered the pry stick and immediately understood the principle of winding.

A student from Ma Jun next to him was repairing a stone cannon. He introduced to Liu Jing: "In the past, the stone cannon was made of hemp rope as strings, and it was not very elastic. This time we used five strands of beef tendon to twist it into a string, which was extremely elastic.

But in this way, it takes a lot of effort to turn the string. If you can no longer pull the string with the previous pull rod, you use a winch, but the winch is not good yet. Add a very long bronze rod to turn the string effortlessly."

After saying that, the student personally demonstrated to Liu Jing. He picked up a copper rod from the ground, passed through the crimped air, and slowly pushed forward. Using the principle of leverage, he creaked the winch, and the extremely elastic bowstring slowly opened. With a "click", the bowstring hung a hanging knife.

The student pulled out the copper rod and smiled at Liu Jing, "It turned out that it was a pull rod, and two people needed to pull it back at the same time. Now the elastic force has doubled and the distance is longer, but only one person is enough. This small improvement has increased the range of the stone cannon by more than fifty steps. Please shoot at the Zhoumu."

He put a round stone weighing more than ten pounds in the stone trough. Liu Jing certainly knew how to operate it. He walked to the stone cannon and stepped on the knife teeth with his foot. He heard a loud "collapse!" sound. The round stone was ejected upwards at an oblique angle, and the cabin was buzzing, and the remaining energy was not over.

This powerful force made Liu Jing amazed, "Not bad, much more powerful than the original one."

Ma Jun stepped forward and smiled, "Or... there is a shortcoming!"

"What else is there to be a shortcoming, sir."

"The governor of the state did not find it... Is it meaningless to defend the city with stone cannons?"

Ma Jun's words reached Liu Jing's heart. How many battles he participated in to defend the city that year, the range of stone cannons was only fifty steps. Except for the final use of them to deal with the nest car, it actually did not play any role. Moreover, it was not very effective against the nest car, which was far less practical than the stone catapult. It was indeed a useless rib.

"Sir, right, but how can I improve it?"

Ma Jun smiled and said, "It's a bit complicated, let my apprentice say it."

The student bowed and stepped forward to pat the stone trough, "Change this place into an iron bag, a bag of thirty iron arrows, or a large crossbow arrow, with a range of up to 300 steps, and can penetrate all shields and armor within 200 steps. It is a powerful tool for dealing with intensive attacks and cavalry."

Liu Jing heard something in his words and asked with a smile: "Have you tried it?"

The student looked back at Ma Jun. Ma Jun nodded with a smile. The student bowed and said, "There is a test stone cannon in craftsmanship, which has been tested many times!"

Liu Jing was overjoyed and immediately said to the generals: "Let's go to craftsmen now!"

The so-called craftsmanship, as the name suggests, is a school that cultivates craftsmen. This is not the original creation of Liu Jing. During the Spring and Autumn Period and the Warring States Period, both Mozi and Gongshu Ban created such schools to cultivate excellent craftsmen.

Jiangxia's craftsmanship is by no means a closed-door business, nor has any theoretical courses. In fact, it has become a concentrated place for inventors and creators, and also a military weapon research center in Jingzhou.

Craftsmanship, also known as Gongshu Academy, are located in the northwest corner of Xiakou City, and cover an area of ​​50 acres, of which the test site alone is 40 acres.

Ma Jun took Liu Jing and dozens of generals into the crossbow hall. The place specializes in researching crossbow arrows. There are more than 50 disciples. Two old craftsmen who have made bows and made crossbows for nearly 40 years became masters. Ma Jun also participated in the development of crossbows.

There was a stone cannon on the stone pier in the backyard of the Gongnutang, which was exactly the same as the improved stone cannon on the ship. However, everyone discovered that the stone trough was changed to an iron bag, and the iron bag was divided into thirty grids, and each grid was inserted into an iron arrow, each of which was about one foot long, which was extremely sharp.

The student continued to introduce: "We call this iron crossbow, the arrow is called the crow arrow, and a thirty arrow."

At this time, Wei Yan next to him asked curiously: "Can you really penetrate everything two hundred steps away?"

Ma Jun smiled, "You can test it!"
