Gu Qing planned to sleep for a few hours, and the scout hurriedly came to report, "Gu Shenzhi, General Wei Chi's has arrived ten miles away. ”

"Lao Yang, you go and greet General Wei Chi." Gu Qing said to Yang Sheng.

Nodding, Yang Sheng left the Potala Palace with hundreds of soldiers, and followed the scouts to greet Wei Chigong.

On the plateau in the dark night, Lu Dongzan on the other side was also rushing to the Potala Palace with tens of thousands of troops, and several soldiers came to report in a panic, "Military division, the royal court has been taken by the Tang army!" ”

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

"Strategist!" A Tibetan man hurriedly persuaded, "Military advisor, do you still remember what Zampu left before leaving, if the Hexi Corridor is defeated, everything will wait for Zampu to find reinforcements before making a decision." ”

"Of course I do." Lu Dongzan was furious, and Songtsen Gampo did explain himself like this, but he couldn't swallow this breath.

After regaining his composure, Lu Dongzan pulled the reins again, "Let's go, let's go and meet Zampu." ”

It was almost dawn, Wei Chigong finally came to the Potala Palace with the army, Gu Qing looked at the long dragon-like baggage, full of more than ten carts of oil, each cart was full of oil drums, Wang Jin smiled and said to Gu Qing, "There are only so many people, and we can only bring these, and we have captured a lot of Tibetan people to help us make firearms." ”

Catch the Tubo people to make firearms, Gu Qing looked at the Tubo people with shackles on their feet, it seems that these people will not live long, no matter whether they win or lose this battle with Tubo, they will not survive.

Wei Chigong walked into the Potala Palace and asked Su Dingfang, "How are you preparing?" ”

"It's almost the same, but the last general is still not at ease, our firearms can be made all the time, as long as there is enough time, there is no problem, there are still too few soldiers." Su Dingfang was worried, "I don't know how many troops Songtsen Gampo will bring." ”

"The old man has already sent someone to Chang'an for help." Wei Chigong said, "Your Majesty will definitely send a large army to reinforce us, this battle is not only about the Hexi Corridor, but also about this trade route to the West, which is a very important step for Datang." ”

With Wei Chigong here, Gu Qing was also a lot more down-to-earth, and made gasoline bombs with Wang Jin.

Gu Qing thought of the thing of fireworks, if it wasn't fireworks fired from the fireworks tube, what if it was something else? A very special idea is formed in the mind.

Wei Chigong's men had been taking in the Tibetan residents for labor to repair the fortifications, and half a month later a Persian envoy came to the Potala Palace.

"A few respected generals of the Tang Dynasty." The Persian envoy bowed and said, "The Persian king wants you to return this place to Songtsen Gampo and return the Hexi Corridor to Tibet. ”

Listening to the lame words of the Persian envoy in Guanzhong, Cheng Chumo slapped the table and stood up, "Put your bullshit, the Hexi Corridor was originally ours." ”

The Persian envoy smiled and said, "If the Tang Dynasty doesn't make a choice, Da Shi, Persia, Tianzhu, Byzantium, and the four kingdoms will have 800,000 allied troops pressing in." ”

800,000 troops! The corners of Wei Chigong's eyes twitched vigorously, this was the largest army that Zhenguan had to face.

"I'd like to ask you." Gu Qing also said, "You help Tubo so much, what benefits does Tubo give you." ”

"I hope that several generals will make a decision as soon as possible." The Persian envoy smiled and saluted, and then left.

"I'll kill him!" Cheng Chumo was about to draw his knife and rise, Su Dingfang hurriedly held him down, "Leave your strength to the big battle later." ”

Cheng Chu's whole body trembled with anger, "Persia is so angry that he dares to meddle in the affairs of the Hexi Corridor." ”

"An army of 800,000 cannot be underestimated." Wei Chi Gong let out a sigh of relief, the reinforcements from the DPRK have not yet arrived, and he looked at Gu Qing, this young man has a firearm manufacturing technique in his hand, will he have any way?

This Persian messenger came not for anything else but to warn.

The atmosphere was heavy, and the next thing to face was the 800,000-strong army of the four Middle Eastern countries.

Gu Qing looked at the repaired fortifications, in half a month, there was already another prototype of a military fortress here, I have to say that Wei Chigong is good at offensive and defensive warfare, and the fortifications here are very good.

Fang Yi's love was worried, the 800,000 army was enough to flood the Potala Palace on this small hill, looked at Gu Qing and said, "Do you have any way?" ”

"Either they die or we die." Gu Qing looked at the bright moon, "I never think I'm a good person, and I don't want to be pretending to be merciful, they want us to die, so don't blame me for not being humane." ”

Coming to Wang Jin's side, Gu Qing said, "How much gasoline has been refined." ”

"More than a thousand pounds." Wang Jin said.

"More people, more speed." Gu Qing said to Wang Jin, "You're welcome, all the Tubo people within a radius of ten miles have been caught to refine gasoline and increase production." ”

"Yes!" Wang Jin replied.

Gu Qing came to Wei Chigong and said, "General, I need the urine of the soldiers in the army." ”

"What?" Wei Chigong didn't come back to his senses for a while.

"I need pee! It can be both human and horse urine. Gu Qing said, "I'm going to make a high incendiary bomb." ”

"Molotov cocktails?!" Wei Chigong said loudly to the bunch of Wu Commanders beside him, "Did you hear that!" Hurry up and do it, if a soldier can't pee, fill me with water until he pees! ”

"Yes!" A large group of captains dispersed.

Regardless of whether this Persian envoy said that there was really an army of 800,000 or not, the entire Tang army was unprecedentedly united, Su Dingfang looked at Gu Qing, a few days have passed, and Gu Qing is the busiest.

"Let's have something to eat." Su Dingfang brought a pot of freshly roasted leg of lamb.

"Thanks, let it go, I'll eat later." Gu Qing drew drawings.

"Is there anything else you need?" Su Dingfang said, "I'll let people prepare." ”

"Clay pots, I need a lot of clay pots." Gu Qing opened his mouth and said, "No matter how much, the more the merrier, as many as I can collect." ”

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

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

Only 40,000 reinforcements? Wei Chigong immediately waved his sleeves and refused, and said to the envoy of the Western Regions, "If you want to get our firearms as reinforcements, then the old man tells you that your 40,000 reinforcements are not enough!" ”

It is not enough to plug the gaps, there are few people in the Western Regions, and 40,000 is already the most that can be squeezed out for the Western Regions, the Tang Army has a tough attitude, and the envoys of the Western Regions have no choice but to go back in disgrace.

Chang'an, following the good news of the Hexi Corridor, Li Er received the military report again, and listened to Fang Xuanling's suggestion to send troops to Tibet, and now Tubo has joined forces with 800,000 troops from the four countries in the Middle East to take back the Hexi Corridor.

"Your Majesty, collect your troops." The eldest grandson Wuji said.

Listening to the words of the eldest grandson Wuji, Li Er hesitated in his heart, it is indeed a great price to pay to win this battle, and if he loses, it is likely to lose the dominance of the Silk Road, if he wins, he will kill his prestige among the four countries in the Middle East, and he can prepare for the century-old plan of the Silk Road.
