The war continued, but it was not a one-sided situation. Due to the addition of 30,000 troops brought by Luo Zhang, the Tubo attack failed to gain any advantage.

Several large-scale attacks were repelled.

In the back, Lu Dongzan stood in a luxurious carriage and looked at Yumen Pass in the distance, frowning.

According to his calculations and what he learned about the situation, Yumenguan should be unable to hold it anymore.

After all, the three surrounding cities have been captured by him, and he already knows exactly what is going on at Yumen Pass.

But nowadays, Yumenguan is still a low-end place to live, which is a bit weird.

"Reporting to the Prime Minister, the number of people who have closed the Jade Gate seems to have increased again, and we have been unable to fill it up several times!" A bearded man reported to Ludong in praise.

"Impossible, it has only been a few days. Even if the Tang army wanted to reinforce, it would be too late. You don't know the Tang army. It is very troublesome for them to mobilize their troops. They have to prepare food, grass and equipment, and they have to negotiate for a long time, and wait for the army to set off.

It will take at least ten days here, and we can only besiege Yumen Pass for five days. They cannot have reinforcements!" Lu Dongzan shook his head and denied.

"But sir, we did see more troops on the city wall. Do you think they are the troops that Zhang Hongyu left behind at the beginning?" Big Beard analyzed.

"The men and horses left behind? He only has tens of thousands of people in total. We have been attacking day and night for the past five days. How can he still have men and horses?"

"Continue to investigate for me. Didn't I say that someone in the city spread the news last night? Why haven't you come yet? Go and ask me!" Lu Dongzan scolded.

"Yes, sir!" The bearded man retreated, and Lu Dongzan frowned even more.

He really didn't believe that Zhang Hongyu would keep men and horses. If he had kept men and horses, they should have been sent out two days ago. You must know that his men and horses almost captured Yumen Pass the day before yesterday. Those people who were hidden were not used at all times. This is absolutely impossible.

impossible.

"Are reinforcements really coming?" Lu Dongzan asked suspiciously.

If reinforcements really arrive, it will be difficult to attack Yumen Pass!

After a while, the bearded man returned again and bowed: "Prime Minister, there was indeed a group of people who went to receive the news from the city last night. It's just that they went but no news was delivered. There were suddenly many torches on the city last night. It should be

The person who delivered the news has been discovered!" Big Beard reported.

Lu Dongzan nodded and stared at Yumen Pass in the distance, not knowing what he was thinking.

In the blink of an eye, half a day passed. Compared with the siege on the pass the day before yesterday, let alone climbing the pass today, even trying to climb up was a luxury. Kerosene, boulders, and rolling logs were constantly being poured down.

This resulted in heavy casualties among the Tubo people, and Lu Dongzan had no choice but to order the withdrawal of his troops.

The attack on Yumen Pass must be considered in the long run.

The moment he saw the Tubo people retreating, the entire Jade Gate closed and there was a loud cheer.

Although they had some casualties in today's battle, the situation was much better than the previous days.

For ordinary soldiers, this is a victory.

But for Luo Zhang and the others, this is just the beginning.

Inside Yumen Pass, in a mansion, all the generals, including Zhang Hongyu, gathered here.

The faces of Luo Zhang and others were pretty good, but the faces of Zhang Hongyu and others were not so good.

"Are you saying that today's battle will use up all the kerosene and other supplies that were saved before?" Luo Zhang looked at Zhang Hongyu and said.

"That's right, they're all used up. This one was prepared just for today. We were already prepared to die before, and the things were shipped early!" Zhang Hongyu explained.

"If it's gone, it's gone. I think the artillery will be delivered tonight. Then let the Tubo people test the power of the artillery!"

"In addition, I also brought a lot of wooden lumps. You should know about these things!" Luo Zhang said with a smile.

Regarding the battle at Yumen Pass, Luo Zhang has no worries at all. He has artillery and wooden knots, and if he can't defeat the Tubo people, then he can go flying!

When Luo Zhang said that there were not only artillery but also wooden lumps, Zhang Hongyu's eyes widened.

Why has he never heard of this thing and seen it with his own eyes? It’s just that he wanted to ask the Ministry of War for some, but was rejected. The output of wood lumps is not high, and several Davids have not even assembled them. You want it at Yumenguan? Wait!

Just wait in line.
