The Jade Gate was closed. Besides Luo Zhang and others, there was another figure that attracted everyone's attention. That was Zhang Qing, Zhang Hongyu's nephew, who clamored with Luo Zhang yesterday to ask Luo Zhang to surrender the pass.
Yesterday, he claimed that Luo Zhang would never be a match for the Tibetan people, and he did not believe in the role that artillery could play.
It stands to reason that Zhang Qing became a traitor and passed information to the Tubo people, so he should be executed as soon as possible. However, Luo Zhang wanted him to die clearly, so he spared his life. He wanted him to open his eyes wide and see the artillery. What kind of power is it, and how were the Tubo people defeated?
It's not just Zhang Qing. In fact, there are many people in Yumen Pass who have Zhang Qing's ideas, but only Zhang Qing took that step and crossed the red line.
Even Zhang Hongyu was worried yesterday, but today Zhang Hongyu is not afraid at all. There are so many wooden bumps. Even if the artillery is not as powerful as imagined, the wooden bumps can scare the Tubo people.
He really wanted to see what it would be like for the Tubo people to be turned upside down by the explosion of wooden lumps.
Zhang Hongyu was suffocated to death after so many days of suffocation. If he hadn't had the courage to refuse to admit defeat, he would have collapsed long ago.
The Tubo army gradually approached. The team was very scattered. There was almost no one in command, and most of them held scimitars in their hands.
As for the siege equipment, apart from crashing cars for ramming the city gates, there are only ladders. It can be said that Tubo has very few siege equipment.
The only advantage was the large number of people. Seeing this, Luo Zhang finally understood why the Tubo people had not conquered them for so many days. In four words, they were technologically backward.
It's no wonder that the Tubo people want to marry Princess Changle. As long as they marry Princess Changle, they can ask for many technical talents from the Tang Dynasty in the betrothal gift, which Li Shimin cannot refuse.
Once they have these technical talents, Tubo's science and technology will be able to advance by leaps and bounds. Just like now, if they have technical talents, they will not only have two kinds of siege equipment, but five, six, seven or eight kinds. many.
He was afraid that before he could reach Yumen Pass, the Tibetans would have captured it.
Thinking about it, Luo Zhang was grateful for his wit. Of course, Li Shimin's wisdom was also indispensable. Another emperor would not be as domineering as Li Shimin. It’s expensive.
After all, the Tang Dynasty was under attack from both sides. The Turks, Gaogouli, and Feng Yike were not able to deal with them. They were not good enemies. Once trouble broke out, the Tang Dynasty would be in danger.
With the sound of horns, the Tubo people rushed towards Yumen Pass, shouting like savages. Luo Zhang almost wanted to laugh at that look.
A plate of loose sand is the best way to describe these Tubo people, and it seems that Lu Dongzan is not that good either.
He was a good man in governing the country, but when it came to marching and fighting, Lu Dongzan was not very good at it.
If there weren't so many people, Zhang Hongyu would be able to hold Yumen Pass without him as reinforcement.
Seeing the Tibetans approaching, the soldiers on the city wall became nervous.
The crossbow in his hand was also held tighter.
The crossbows they used today were a little different from those in the past. There was a wooden knot tied to them. Although this increased the weight of the arrows, the shooting distance became shorter.
But its power has been multiplied. Now they just wait for the order from above, they will light the wooden knots and shoot them into the Tubo crowd.
This was also explained before, they just need to execute it.
Seeing that it was almost done, Luo Zhang waved his hand, and a guard who followed him from Chang'an immediately went down to give orders.
I saw that the artillery pieces that were originally covered with oilcloth were lifted off the oilcloth and pushed to the city wall. The muzzles of the cannons were facing into the distance, and a famous soldier adjusted the distance.
These people were all brought from Chang'an and specialized in controlling artillery.
Without these people, the artillery would become a decoration. No matter how awesome Luo Zhang was, he would not be able to control ten artillery pieces at the same time.
When the soldiers controlling the artillery stood up and raised their hands, it meant that they were ready.
When the first ladder was erected on the city wall of Yumen Pass, Luo Zhang waved his hand again, and a captain beside him took out a big flag and waved it in the air.
This is the signal sent by Luo Zhang to those who control the artillery. At the same time, Zhang Hongyu also received instructions to attack!
There was only a roaring sound, followed closely by a whooshing sound.
What followed was a loud banging sound that exploded not far outside Yumen Pass.
