Pei Min and Gao Xianzhi are both rare generals in the world. They are thousands of miles away, but the deduction of war is as if they had seen it with their own eyes.

Wang Zhongsi was indeed not in a hurry to attack.

I was anxious and couldn't eat hot tofu, especially in a strong confrontation with Tubo.

They who have already gained the lead should first be invincible and then find the way to defeat the enemy.

Therefore, after Wang Zhongsi entered Qinghai Lake, he devoted his main focus to the renovation of Yinglong City.

At the same time, it is also intended to allow the Tang army to adapt to the altitude sickness on Qinghai Lake, so that they can get used to the climate here, and avoid being overly affected by the altitude sickness during wartime and affecting their combat effectiveness.

Faced with Wang Zhongsi's persistence, Dazhalugong chose to attack without any surprise, intending to use the convenience of ice and snow to seal the lake to erase the strategic initiative of the Tang army.

But the details are accurate to Pei Min, and Gao Xianzhi thinks slightly differently.

According to the two of them, Yinglong City is a newly built small town. After all, it has only been built for several months and has limited defense facilities.

However, what appeared in front of Dazalugong was...

Qinghai Lake is already a plateau area, so the climate is much colder than the Western Regions, but the ice age of Qinghai Lake is much later than that of the Kabul River.

The ancients did not understand this principle, but the knowledge from later generations explained it because of salt water.

Qinghai Lake is a saltwater lake, and the freezing point of salt water is much lower than that of water.

This is also the reason why highways freeze and salt will spread on the road.

As long as the water absorbs salt and turns into salt water, it will not be easy to solidify.

But as long as the freezing point of salt water is reached, this method is ineffective.

As a saltwater lake, Qinghai Lake will not enter the ice age until the coldest season.

The south bank of Qinghai Lake!

Dazha Lugong did not hide his ambitions from the corresponding Longcheng. He approached Qinghai Lake early in the morning and began to manufacture siege equipment.

It was snowing heavily yesterday, and it was the coldest time.

Qinghai Lake has frozen, but for safety reasons, he chose to wait for an extra day.

Dazalugong looked at the fast horses running in front of him, and saw hundreds of horses running on the ice without any reaction. They were stronger than the flat ground, and knew that the time for the attack was coming.

"Send the whole army! Follow me to flatten Yinglong City!"

The voice of the wind echoed over Qinghai Lake, and the tone was filled with confidence in winning.

This attack is related to the initiative in future wars, and Dazalugong has taken out all his strength.

During the days when he was waiting for the freezing of Qinghai Lake, he mobilized a total of 80,000 troops. Nearly 150,000 people in Qinghai Lake cut down trees, mined and transported stones, and built siege equipment.

Tubo has always greedily absorbed the technology of the Tang Dynasty, especially when the Tubo army gods were rampant in the world, and obtained a large number of spoiled talents from the Tang Dynasty.

Today, although Tubo's technology cannot keep up with the Tang Dynasty, it is also the most advanced among all the surrounding dynasties.

There are all kinds of siege equipment such as stone shaving machines, cloud ladders, siege towers, nest chariots, chariots, and trench bridges.

Before this, Dazalugong had already found out.

There are no large city-defense equipment in Yinglong City. On the one hand, it is because Yinglong City and Mo Li are too far from the Central Plains, so large city-defense equipment is extremely difficult to transport; on the other hand, it is because there is no wood around Yinglong City, which is not enough to build large city-defense equipment. What is crucial is that the purpose of the Tang army's advance this time is to attack, not defense.

It took a lot of effort to make defensive equipment, but it only took one month to use it, which was not cost-effective at all.

Therefore, the Tang army only made many light equipment that are easy to carry and available for offense and defense.

Even if the Tang Dynasty's technology was so great, how could it be dealt with their heavy siege equipment only with light equipment?

Moreover, Yinglong City has only been a new start for more than a month, and the city defense is simple. It is easy to use a large number of heavy equipment to face a small city. Dazhalugong really can't think of any invincible reason.

Adjutant Bu Gexi strode to his side and whispered loudly: "Marson, please allow me to take down Yinglong City for you."

"Okay!" Dazalugong agreed. He did not intend to command this simple siege battle himself.

After taking Yinglong City, the showdown with the Tang Army's main force was what he thought he should consider.

"You will dispatch the siege equipment. I will give you half a month to take Yinglong City within fifteen days!"

Dazha Lugong still leaves a way out for himself.

The ice period of Qinghai Lake is not long, usually between one month and a half.

Even if Buge likes to attack the city, there is still room for maneuver.

Bugexi seemed to have been greatly humiliated, and said angrily with red neck: "Marcedess is too underestimating me Bugexi. For the broken city of Yinglong City, I will give me ten days. No, in just five days, the Marshal can stand on the top of Yinglong City to watch the sunrise."

After a pause, he added: "Of course, if the city wall collapses, there will be no way."

Dazalugong heard the confidence of his beloved general from the cold joke and laughed even more satisfied.

"Don't talk big, I'll wait for your good news!"

Buge took the order happily and went there.

There is no reason not to strive for this achievement that comes to your door.

Bugexi led his troops northward.

Qinghai Lake was originally a base of thousands of miles, but due to the blockage of leak channels, the range has been shrinking, and the circumference is only about 800 miles to this day.

Longju Island is just in the middle of Qinghai Lake, and it is nearly a hundred miles from the shore of Qinghai Lake to Longju Island.

Buge likes to transport large siege equipment, and the marching rate is not fast.

After slowly forcing for more than ten miles, the stalkers sent out came to the army with a look of ghosts and reported: "Report, report to the deputy commander, Tang, and Tang army built a fortress along the entire Longju Island. We cannot access Longju Island at all and cannot explore the situation on the island."

Bugexi waved his whip and whipped his head out of blood, cursing angrily: "I am timid and dare not go deeper, so I lied about military information. How could it be? When I don't understand the situation in Longju Island?"

The entire Longju Island is six miles long from east to west and two miles wide from north to south. It is shaped like a snail shell, and the top of the mountain is twenty feet above the lake.

Basically every residents of Qinghai Lake know this.

This is not a small project to build a fortress around Longju Island.

Even if you use 100,000 labor, you will never succeed in the short term.

How could the Tang army build a fortress around Longju Island?

Tanma said aggrievedly: "I don't believe in humble vocations, but that's the truth. The deputy commander can investigate it himself. If there is a small lie, you don't need to do it, and I will end up myself."

Buge smiled happily and said ruthlessly: "Then I want to see what Tang Jun has repaired in this short half month!"

He galloped towards Longju Island in anger.
Chapter completed!
