Pei Min and Gao Xianzhi are both rare generals in the world, they are thousands of miles away, but they deduce the battle as if they have seen it with their own eyes.

Wang Zhongsi was indeed not in a hurry to attack.

I can't eat hot tofu in a hurry, especially against a strong enemy like Tubo.

They have already taken the lead, and it is the royal way to be invincible first, and then to find a way to defeat the enemy.

Therefore, after Wang Zhongsi entered Qinghai Lake, he spent his main thoughts on the repair of Yinglong City.

At the same time, it was also intended to allow the Tang Army to adapt to altitude sickness on Qinghai Lake, so that they could get used to the climate here, so as to avoid being overly affected by altitude sickness during wartime, which would affect their combat effectiveness.

In the face of Wang Zhongsi's insistence, Dazaru Gong chose to attack without surprise, intending to use the convenience of ice and snow to close the lake and obliterate the strategic initiative of the Tang army.

But the details were indeed slightly different from what Pei Min and Gao Xianzhi thought.

In the calculations of the two of them, Yinglong City was a newly built small city, after all, it was only a few months to build, and the defense facilities were limited.

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

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

The ancients did not understand this truth, and the knowledge of later generations explained that it was because of the salt water.

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

This is also the reason why the highway is icy and salt is sprinkled on the road.

As long as the water absorbs salt and becomes brine, it is not easy to solidify.

However, as long as the freezing point of the brine is reached, this method is ineffective.

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

The south shore of Qinghai Lake!

Dazaru Gong did not hide his ambition to correspond to Dragon City, approached Qinghai Lake early in the morning, and began to manufacture siege equipment.

Yesterday there was a lot of snowfall, and it was the coldest season.

Qinghai Lake had frozen, but to be on the safe side, he chose to wait an extra day.

Dazarugon looked at the fast horses rushing in front of him, and when he saw hundreds of horses running on the ice without any reaction, and when he was stronger than the flat ground, he knew that the time had come to attack.

"Command the whole army! Follow me to Pingying Dragon City! ”

The high-spirited voice echoed over Qinghai Lake, and the tone was full of confidence in victory.

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

During the days when he waited for Qinghai Lake to freeze, he mobilized an army of 80,000 people, and nearly 150,000 people in the entire 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 in the era when the Tubo military gods were rampant in the world, and obtained a large number of war trophies and talents from the Tang Dynasty.

Although the technology of Tibet cannot keep up with the pace of the Tang Dynasty, it is also the most advanced among all the surrounding dynasties.

There are all kinds of siege equipment such as stone throwing machines, ladders, siege towers, nest cars, crane cars, pointed heads, and moats.

Before that, Dazarugon had already figured it out.

There are no large-scale city-guarding equipment in Yinglong City, on the one hand, because Yinglongcheng and Mo are too far away from the Central Plains, and large-scale city-guarding equipment is extremely difficult to transport; On the one hand, it is also because there is no wood around Yinglong City, which is not enough to build large-scale city defense equipment; The most important thing is that the purpose of the Tang army's advance this time is to attack, not to defend.

It took a lot of effort to make defensive equipment, but it could only be used for a month, and it was not cost-effective at all.

Therefore, the Tang Army only made a lot of light equipment that was easy to carry and could be used for both offense and defense.

Even if the Tang Dynasty's technology was so good, how could they deal with their heavy siege equipment with only light weapons?

What's more, Yinglong City's new establishment is only a short period of more than a month, and the city defense is simple, with a large number of heavy equipment against a small city, Dazaru Gong really can't think of any reason to be invincible.

Adjutant Bu Gexi strode to his side and said in a loud voice, "Marshal, please allow me to take this Yinglong City for you." ”

"Good!" Dazaru Gong promised that he did not intend to command this simple siege battle himself.

After taking Ying Long City, the duel with the main force of the Tang Army was something he felt he should consider.

"The siege equipment, dispatched by you, will give you half a month, and within fifteen days, Yinglong City will be taken!"

Dazarugon still left himself a way back.

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

Even if Bu Gexi is not good at attacking the city, there is still room for maneuver.

Bu Gexi seemed to have been greatly humiliated, and said angrily with a red neck: "Marshal is too underestimated to me Bu Gexi, just give me ten days for the broken city of Yinglong City, no, as long as it is five days, the marshal can stand at the head of Yinglong City and watch the sunrise." ”

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

Dazaru Gong heard the confidence of his favorite general from the cold joke, and laughed with satisfaction.

"Hugh is going to say big things, I'm waiting for your good news!"

Bu Ge was overjoyed and took the order.

There is no reason not to strive for this merit sent to the door.

Bu Gexi led the troops all the way north.

Qinghai Lake was originally based on thousands of miles, but due to the blockage of the leakage channel, the scope has been shrinking, and the circumference is only about 800 miles today.

Longju Island is right in the middle of Qinghai Lake, and there are nearly 100 miles from the shore of Qinghai Lake to Longju Island.

Bugexi was transporting large siege equipment, and the march was not fast.

Slowly and forcibly traveled more than ten miles, but the scout horse sent out came to the front of the army with a ghostly face and reported: "Report, report to the deputy marshal, Tang, the Tang army has built a fortress along the entire Longju Island, we can't go to Longju Island at all, and we can't explore the situation on the island." ”

Bu Gexi waved his whip over, and the head of the horse was bleeding, and he scolded angrily: "I am cowardly, I dare not go deeper, and lie about the military situation." How is it possible when I don't know about the situation on Ryukoma Island? ”

The whole island of Longju Island is six miles long from east to west, two miles wide from north to south, shaped like a snail shell, and the top of the mountain is 20 zhang higher than the lake surface.

This is known to almost every resident of Qinghai Lake.

The construction of forts around Ryukoma Island on all sides is not a small project.

Even if 100,000 laborers are used, it will not be possible to succeed in the short term.

How could the Tang Army build a fortress around the entire island of Longju Island?

Tanma said aggrievedly: "I don't believe in lowly duties, but that's the case." The deputy marshal can personally investigate, if the small one has half a lie, you don't need to do it, I will end up myself. ”

Bu Ge smiled happily and said fiercely: "Then I want to see what the Tang army has repaired in this short period of half a month!" ”

He galloped towards Ryukoma Island in a rage.

When I came closer, I looked at the ice wall in front of me with sand and soil, my head was dizzy, and I suddenly felt that my neck was cold, and I was afraid that I couldn't keep this good head.
