The Sui army continued to attack in the next three days, and the Tang army paid a heavy price. Li Er not only took the battle himself, but also suffered minor injuries, so he managed to defend Tongguan with difficulty.

"Your Highness, no more. If the reinforcements don't come, we will not be able to defend them."

Duan Zhixuan rushed to Li Er and wailed.

Li Er pulled Duan Zhixuan's collar and roared: "If you can't defend, you have to guard it, and Tongguan cannot be thrown away.

In just a few days, if we lose Tongguan, we will have no face to return to Chang'an.

The reinforcements returned soon.”

After saying that, Li Er let go of Duan Zhixuan's collar, covered the bleeding wound, and sat back on his seat.

"Yes, your highness don't worry. Even if you die in the city gate, you will never let the Sui army break through."

After saying that, Duan Zhixuan rushed out.

"Your Highness, do you want the Black Armored Iron Cavalry to protect you and leave first? It's too dangerous here."

After there was no one around, Changsun Wuji whispered to Li Er.

As a result, Li Er's cold gaze was received.

Changsun Wuji had never seen Li Er's eyes before, and he was so scared that he didn't dare to speak.

"General, Your Highness, here are you, reinforcements are here."

On September 26, the Tang army in Tongguan finally waited for the reinforcements they were waiting for.

After receiving Li Er's letter of help from Li Er, Li Yuan immediately realized that the situation in Tongguan might be worse than they thought.

Li Yuan is quite familiar with his second son, and he is very capable and never admits defeat.

Li Er led the Tang army to fight for so long, but he had never asked for help in such a hurry.

Therefore, Li Yuan did not dare to delay, so he immediately sent Pei Ji to lead an army of 150,000 to Tongguan.

At the same time, this time, Li Tang not only sent out all elite soldiers, but also many powerful generals and wise generals, such as Li Yuanba, the number one general of the Sui and Tang Dynasties, and Li Jing, the war god, were all among them.

In fact, these 150,000 elite Li Tang troops were originally going to rush to Tongguan.

However, the original plan was half a month later, and Li Yuan thought that with the tens of thousands of people in Li Er's hand, it was enough to hold on to Tongguan for more than half a month.

But now, the situation has taken a sharp turn, and Li Yuan has to let the 150,000 Tang troops set out in advance.

As for food and grass, they only brought the remaining food for less than a month, and Li Yuan could only find a way to raise the remaining food.

After three days of rapid march, Li Jing led Li Yuanba and 30,000 elite cavalry of the Tang army to arrive at Tongguan first.

Pei Ji brought the remaining 120,000 Tang troops, and was still behind.

"I am humble in Li Jing, see the general, see your highness."

After Li Jing led his troops to Tongguan, Liu Hongji and Li Er went out to greet him excitedly.

Boom boom boom boom!

At this time, the Sui army in front of Tongguan was still siegeing the city, and the sound of thunder explosion could be vaguely heard.

"Second brother."

"Yuanba, why are you here too?"

"Second brother, I heard from my father that you have encountered difficulties in Tongguan, so I will naturally come to help you."

Li Yuanba carried a pair of heavy copper hammers and said happily.

Li Yuanba’s IQ is a little problem. He looks like a child and is closest to Li Er.

"Don't say so much, Li Jing, immediately let the army enter the pass.

The Sui army is now siegeing the city, and the front-line soldiers are very hard to defend and need support in urgent need of support.

You will immediately lead troops to reinforce."

At this time, Li Er had no time to reminisce about the past and said to Li Jing.

At the same time, Li Er didn't care about what Li Jing brought, and they were all cavalry. Now the cavalry can only be used as infantry first.

We must first repel the Sui army's attack.

"Yes, Your Highness, I will lead the reinforcements."

Li Jing could see from Li Er's expression that the emergency situation in Tongguan was so urgent that he dared not delay it and immediately entered the pass to reinforcements.

"Second brother, I'm also on the wall, and I have to fight the Sui army."

Li Yuanba said excitedly.

Immediately, Li Yuanba carried a pair of large copper hammers and climbed the Tongguan Wall.

"Kill!"

At this time, a shocking shouts of killing broke out above Tongguan.

A large number of Sui soldiers had already been killed in Tongguan, and the soldiers on both sides were fighting for control at the critical moment.

At this time, because the Sui army soldiers had already rushed to Chengguan, the Sui army archers and crossbows outside the city no longer shot arrows, so as not to hurt their own people.

"You tyrants, dare to hurt my second brother and kill you."

Li Yuanba climbed up to the wall, and his face was still smiling. Every time the copper hammer in his hand was swung out, a Sui soldier would fly backwards and vomit blood and die.

No one could withstand Li Yuanba's hammer. He rushed to the front and cleared the entire wall by himself. Countless Sui soldiers were killed by him.

In the end, most of the Sui army that climbed the city wall were killed and partially fled.

The Sui army failed this time.

"Aoah!"

On the top of Tongguan city, the Tang soldiers shouted, and their morale rose sharply.

On the one hand, it was because the Sui army was repelled, and on the other hand, it was because reinforcements came.

Moreover, the new Tang soldiers experienced a victory as soon as they arrived, and their morale naturally rose.

On the contrary, the Tang soldiers who had been guarding the pass for more than a week were not as happy as the new Tang soldiers.

Because, they knew that they had repelled the Sui army and when the Sui army attacked again tomorrow, they would face waves of endless rain of arrows covered with shooting.

Then, their casualties will be more.

In fact, they now hope to let Sui soldiers attack the city wall and fight with the Sui soldiers.

In this way, they would not have to withstand the terrifying rain of arrows from the Sui army.

"Governor, our troops who attacked Tongguan were killed by the Sui army.

According to the report of the retired soldiers, reinforcements came from Tongguan."

Taishici came to Zhou Yu and said.

"Well, count the time, the reinforcements of the Tang army should arrive too.

As soon as the Tang army's reinforcements arrived, Li Er should have fought back. He was always passively beaten, which was not his personality."

"How have Lu Su and Lu Meng practiced these days?"

"all the best."

"That's good, tell Lu Su and Lu Meng to prepare them.

In the next battle, whether or not you can eat the elite heavy armored elite cavalry in the Tang army depends on them."

"Governor, how did you know that the Tang army would send that heavy armored cavalry to fight?

In recent days, Tongguan has been in such a crisis, and even the heavy armored cavalry has not seen the battle.

It can be seen that Li Er attaches great importance to this heavy armored cavalry, and he may not be sent out easily."

Taishici was worried.

"Before, Li Er did not send that heavy armored cavalry to fight, which means he thought the time was not right.

Now, their reinforcements arrived, with strong troops and strong horses. Li Er would no longer be willing to be in Tongguan, and would be hit by our arrow rain every day."
