In order to prevent the Goryeo defenders from destroying the perfect Tushan project, Li Daozong specially sent Comrade Fu Ai, the commander of Guoyi, to garrison the top of Tushan for a long time.

But since ancient times, there has been a kind of project called the tofu slag project.

This dirt and mountain project is a thorough tofu slag project.

There are still two days left before the completion of the project, the earth mountain collapsed, the earth mountain collapsed, all the hard work was in vain, Li Er was originally very curious about the secret letter sent by Xu Yang, 'the earth and mountain collapse, then the fire attack', the result was so quickly fulfilled.

Li Ertie went to the place where the earth mountain collapsed with a blue face, in fact, it was a collapse, not a complete collapse, but the soil at the bottom was too soft to bear the thicker and thicker weight above, so the collapse occurred.

But Li Er doesn't ask this, TMD, half a month of busy work, what about Li Daozong?

Li Daozong called Li Er, who was limping, because he had a foot injury and was unable to move, and his brother was recuperating in the camp.

What do you eat?

Li Daozong looked at Tushan and was dumbfounded.

TMD, what about Wei Fu Ai?

Wei Fu Ai was called by Li Daozong, his brother didn't know about the quality problem here, and he didn't know that the earth mountain had collapsed because of the quality problem.

What do you eat?

Yu Fu Ai looked at Tushan and was dumbfounded.

Li Daozong asked the soldiers to tie up Captain Fu Ai, you girl, tell you to eat, drink and stay on the dirt mountain, you are not allowed to come down without my order, you dare to go down the mountain without permission?

Wei Fu Ai was pulled out and chopped.

Li Er asked the soldiers to tie up Li Daozong, you girl. How can you be worthy of me personally acupuncture your foot injury?

Li Daozong was pulled out. Closed the confinement.

The angry Li Er remembered the secret letter Xu Yang sent to him at this time. I read it again, Xu Yang's letter didn't say much actual things, and the writing was ugly, Li Er finally understood what Xu Yang meant from the beginning to the end, the built earth mountain would collapse, and at this time, the fire oil could be poured into the river channel of Anshi City, and then ignited, this thing would not be extinguished when it met with water. The more it burns, the more vigorous it becomes, and the only way to extinguish it is to cover it with soil, but the Koreans don't know it, so the fire built by Xu Yang to cooperate with the siege will definitely have a miraculous effect.

Shocked by the prediction technique of the Ghost Valley in his heart, Li Er decided to adopt Xu Yang's construction.

Jian yì adopted, and the next step was the specific siege steps, at this time, Li Daozong, who came out of confinement, was barefoot and limped to Li Er to ask for his guilt.

"You know no, just your dereliction of duty. According to military law, he should be beheaded. Li Er's head was a big drink.

But for Li Daozong, hit him. OK; Scold him, it's okay; If you want to kill him, you can't do it.

After all, it is Lao Li's own family, and Li Er will not be a killer.

So after the fight and scolding, Li Er said: "When Emperor Wu of the Han Dynasty killed the general Wang Hui, it is better for Qin Mugong to reuse Meng Ming for the second time, and you have merit in breaking Gaimu City and Liaodong City, so I will pardon you from dying, but the next plan, I want you to atone for your sins, if you mess up again, don't blame me for being polite."

Comrade Li Daozong was trembling and thankful.

Sometimes history is so painful, this tofu scum project does not collapse sooner or later, it just so happened that the day Comrade Wei Fu Ai left suddenly collapsed, Wei Fu Ai, who has always obeyed the rules, has been busy working on the earth mountain for half a month, just because he didn't stick to the last moment, the head fell to the ground, and there was no girl bubble, and there was no bar, why did you say that he suddenly left on the day of the siege of the city?

History is always strikingly similar, and if there is no Xu Yang, Li Er's pace of the Eastern Expedition is likely to stop here as in history, and in the end it can be regarded as a retreat.

However, since Xu Yang is here, he will definitely not let such a fucking history repeat itself, so there are a thousand barrels of fire oil brought by Zhang Liang from the waterway.

Fire oil, in fact, is a kind of crude oil that has not been processed and refined, and the viscosity is very large black-brown liquid, which is about the same length as asphalt after high temperature.

Although it has not been refined, it is still less dense than underwater, can float on the water, and has a slightly higher ignition point than the oil and diesel extracted from it, but it is still the best fuel for continuous combustion.

The oil was all mined from an oil mine found in Qiuci, and Xu Yang used only 10,000 stone of grain to exchange for a huge oil field, and the spies who reported it described the situation there as "the mountains northwest of Qiuci in China, like a plaster flowing out of a river, traveling for miles into the ground, like a Daigo, very smelly, burning with fire." "Xu Yang is like discovering a new world, and he asked his caravan to travel overnight to Qiuzi Country to buy this mountain and mine oil mines.

The king of Qiuzi was also very happy to see someone stupid enough to exchange grain for this kind of barren land, and both sides of the transaction were very happy, and in less than half a year, Xu Yang transported back thousands of barrels of oil from this oil field, most of which were stored, and a small amount was taken to Nanshan Academy for research projects.

Li Er's siege plan was quickly determined, in fact, with Xu Yang's construction, the siege was already very clear, that is, first use fire oil to set the city on fire, and then use the army to break through the city.

The fire burned the city, it is advisable to need a strong wind, today's weather is very good, the northwest wind is blowing very strong, a cold snap from North Siberia brings not only a strong wind, but also a little chill.

Li Er wrapped in a mink cloak, he has not been in good health recently, not only on fire, but also on his back with a carbuncle, not only fever, stomach cold, headache, but also often loss of appetite, so he wants to end the war more and more.

Li Daozong personally went into battle today, and Li Er matched him with two fierce generals, Su Dingfang and Wang Wendu, both of whom were victorious generals who served under Cheng Yanjin before, and this time they also went out with the army.

The soldiers were ordered to pour barrels of fire oil into the river that flowed into Anshi City, and the Goryeo people who watched the city wall were shouting, and they thought that the Tang Dynasty was poisoning.

The black-brown oil looked disgusting and had a strange smell, so it was no wonder that the Koreans thought that the Tang people were poisoning.

Yang Wanchun himself climbed the city tower and scolded Li Er for being despicable on the city tower with his throat.

Only a rain of arrows responded to him.

Li Er didn't care about this, and now all he could think about was to take the city in front of him, and then quickly clear the obstacles, take Pyongyang, and then return to the DPRK.

The oil was poured very quickly, only half a day, a thousand barrels of oil were almost poured, and the spies reported that the river in front of the residents in the city was full of black oil oil, and the Koreans in the city did not make any big moves, they were waiting for the living water to discharge all the oil downstream.

When Li Er heard this report, he nodded with satisfaction, and then ordered to light a fire to attack the city.

As soon as it was ignited, a fire dragon ignited in the river, and black smoke soared into the sky, entering the city from outside the river of Anshi City.

The soldiers besieging the city were waiting for this moment, and the two generals, Su Dingfang and Wang Wendu, each led 10,000 men to launch a fierce attack on the southeast and west walls of Anshi City.

Faced with the burning river and the burning buildings next to the river, they instinctively began to pour water to put out the fire, but pouring water into the oil was fatal, and the fire did not decrease, but became bigger and bigger.

The black smoke in the sky seemed to drown the city of Anshi, and fires began to spread everywhere, and most of the soldiers on the city wall rushed to the city to help put out the fire, but once the water was poured, the fire would become even more uncontrollable.

Faced with this situation, the Goryeo people in the city shouted for the devil, and they felt a spiritual fear of this kind of ghost fire that could not be extinguished by water.

There was a howl of ghosts and wolves in the city of Anshi, but the besieging soldiers outside the city felt more relaxed than ever, and there were almost no big casualties, and the Tang army began to climb this towering tower one after another, but when they looked at the scene in the tower, they were all stunned.

At this time, the city of Anshi was like a purgatory on earth, with fires rising into the sky everywhere and blazing black smoke...... (To be continued......)
