Gu Qing was going to sleep for a few hours, and the scout hurriedly came to report, "Gu Shenzhi, General Yuchi's is already ten miles away."

"Old Yang, go and welcome General Yuchi." Gu Qing said to Yang Sheng.

Nodding, Yang Sheng left the Potala Palace with hundreds of soldiers and followed the scout to welcome Yuchi Gong over.

On the plateau of darkness, Lu Dongzan on the other side was also rushing to the Potala Palace with tens of thousands of troops. Several soldiers came to report in panic, "Military advisor, Wang Ting was taken down by the Tang army!"

"Let's go and take it back!" Lu Dongzan said gritting his teeth.

"Military advisor!" A Tubo man hurriedly persuaded, "Military advisor, but I still remember what Zanpu left before leaving. If the Hexi Corridor is defeated, everything will be decided after Zanpu finds reinforcements."

"Of course I know." Lu Dongzan was furious. Songtsen Gampo did explain this to himself, but he couldn't swallow his breath.

After calming down, Lu Dongzan pulled up the reins again, "Let's go and meet Zanpu."

It was almost dawn, and Yuchi Gong finally brought the army to the Potala Palace. Gu Qing looked at the long dragon-like baggage, full of more than ten trucks of oil, and each truck was filled with oil barrels. Wang Jin smiled and said to Gu Qing, "There are only so many people, and we can bring only these. We caught many Tubo people to help us make firearms."

When they caught Tubo people to build firearms, Gu Qing looked at the Tubo people with shackles on both feet. It seemed that these people would not live long. They would not survive whether they lost or won or won in this battle with Tubo.

Yuchi Gong walked into the Potala Palace and asked Su Dingfang, "How are you doing?"

"It's almost done, but the generals are still worried. Our firearms can be built all the time. As long as there is enough time, there is no problem with how many soldiers are needed. "Su Dingfang was worried, "I don't know how many troops Songtsen Gampo brought."

"I have sent someone to ask for help from Chang'an." Yuchi Gong said, "Your Majesty will definitely send a large army to reinforce us. This battle is not only related to the Hexi Corridor, but also to this trade route to the West. This is a very important step for the Tang Dynasty."

With Yuchi Gong here, Gu Qing felt much more at ease and made gasoline bombs with Wang Jin.

Gu Qing thought of the fireworks. What if the fireworks were fired in the fireworks, what if it was not fireworks to be fireworks? A very special idea was formed in his mind.

Yuchi Gong's men have been detaining Tubo residents to work on labor to repair fortifications. Half a month later, a Persian envoy came to the Potala Palace.

"Several respected generals of the Tang Dynasty." The Persian envoy bowed and said, "The Persian king hopes that you will return the place to Songtsen Gampo and return the Hexi Corridor to Tubo."

Listening to the Persian envoy's poor Guanzhong words, Cheng Chumo slapped the table and said, "Don't you shit, the Hexi Corridor is ours."

The Persian envoy smiled and said, "If the Tang Dynasty did not make a choice, the four countries would have 800,000 coalition forces to advance."

Eighty-hundred-thousand-strong army! Yuchi Gong's eyes twitched hard. This was the largest army to face since Zhenguan.

"I want to ask you," Gu Qing also said, "What benefits did Tubo give you if you help Tubo like this?"

"I hope the generals will make a decision soon." The Persian messenger smiled and saluted, then left.

"I'll kill him!" Cheng Chumo was about to draw his sword, and Su Dingfang hurriedly held him down, "Leave your strength to the battle behind."

Cheng Chu was silent and trembling all over, "Persia is so angry that she dares to interfere in the Hexi Corridor."

"The 800,000 army cannot be underestimated." Yuchi Gong breathed a sigh of relief. The reinforcements in the court have not arrived yet. He looked at Gu Qing. What would he do if this young talented man holds a firearm to create a technique?

This Persian messenger came for nothing but for warning.

The atmosphere was very heavy, and the next thing we had to face was the 800,000 army of the four Middle East countries.

Gu Qing looked at the repaired fortifications. In half a month, another military fortress had already formed. I have to say that Yuchi Gong is good at offensive and defensive warfare, and the fortifications here are very well done.

Fang Yiai was worried that the 800,000 army was enough to submerge the Potala Palace on this small hill. He looked at Gu Qing and said, "Do you have any solutions?"

"Either they die or we die." Gu Qing looked at the bright moon, "I never think I am a good person, and I don't want to be hypocritical merciful. If they want us to die, don't blame me for being inhumane."

Gu Qing came to Wang Jin and said, "How much gasoline has been refined?"

"It's more than a thousand pounds." Wang Jin said.

"Increase the manpower and speed up." Gu Qing said to Wang Jin, "Don't be polite. All the Tubo people in a radius of ten miles were captured to refine gasoline and increase production."

"Yes!" Wang Jin replied.

Gu Qing came to Yuchi Gong and said, "General, I need the urine of soldiers in the army."

"What?" Yuchi Gong did not come back to his senses for a moment.

"I need to pee! It's okay whether it's human or horse urination." Gu Qing said, "I want to do a strong incendiary bomb."

"Incendiary bombs?" Yuchi Gong said loudly to the group of sergeants beside him, "Did you hear it? Go and do it quickly. If any soldier can't pee, pour me water until he urinates!"

"Yes!" A large group of squadrons dispersed.

Regardless of whether the Persian envoy said that there was really an army of 800,000, the entire Tang army was united like never before, Su Dingfang looked at Gu Qing. A few days passed, Gu Qing was the busiest one.

"Eat something." Su Dingfang brought a basin of freshly roasted lamb legs.

"Thank you, let's leave it, I'll eat later." Gu Qing drew the drawings.

"Do you need anything else?" Su Dingfang said, "I'll ask someone to prepare."

"Clay pots, I need a lot of clay pots." Gu Qing said, "No matter how many, the more, the better. I can search for as much as I can."

"Okay, I'll do it now." Su Dingfang said.

The entire Tang army began to make firearms with Gu Qing as the core. Today, the envoys from the Western Regions countries also came here and were willing to send 40,000 troops to help the Tang army.

There are only 40,000 reinforcements? Yuchi Gong immediately waved his sleeves and refused and said to the envoys of the Western Regions, "If you want to get our firearms as reinforcements, then I will tell you that your 40,000 reinforcements are not enough to plug into the teeth!"

There are not enough people in the Western Regions. There are few people in the Western Regions, and 40,000 is the most popular for the Western Regions. The Tang army is tough, so the envoys from the Western Regions have to go back in shame.

Chang'an, after the good news from the Hexi Corridor, Li Er received the military newspaper. After listening to Fang Xuanling's suggestion, he sent troops to Tubo. Now Tubo has joined forces with 800,000 troops from the four Middle East countries to take back the Hexi Corridor.

"Your Majesty, stop the troops." Changsun Wuji said.
