And what is Yang Yi, the main owner, doing at this time?

Yang Yizheng led a group of guards around the ruins of the western city of Tongzhou.

Yang Yi wanted to find out what Lu Yuanliang had done to attract such a big fire, until now, the entire Xicheng city wall was still unbearably warm, and even the bricks on the ground were still hot.

Tens of thousands of charred bodies have been carried out of the city by soldiers for burial, leaving piles of blackened debris.

Yang Yi invited the logistics officer to ask, and there was nothing wrong with the oil bomb used by Lu Yuanliang, it was the most ordinary oil bomb.

Thinking of his previous analysis, Yang Yi quickly targeted the batch of armaments and materials of the Shu army that were intercepted by Wei Song, but unfortunately, those materials were moved to the city wall by Zhu Qingxian to resist the Shu army, and basically all of them had been turned to ashes with the fire.

In particular, the more than 30 trebuchets were burned into more than 30 pairs of pitch-black charcoal, which were neatly arranged on the city wall.

Yang Yi wandered around the city wall for a long time without finding anything unusual, and when he finally walked next to a pile of trebuchet wreckage, Yang Yi found that there were two parts in the wreckage that had not been completely charred.

Yang Yi bent down and picked up the two stick-like parts, took them in front of him and waved them casually twice, and suddenly found that there seemed to be another familiar smell in the smell of charcoal.

Yang Yi moved the stick closer in confusion, sniffed hard, and frowned: "Gunpowder? ”

Yang Yi swore that he was absolutely not mistaken, after the gunpowder burned, the pungent smell of sulfur dioxide was very distinctive.

"That's not right! Drunken maniacs have not used thunderbolts, how can they smell of gunpowder? Yang Yi said in surprise.

Yang Yi had repeatedly asked the quartermaster, but Lu Yuanliang didn't need to use a thunderbolt that he brought. And thunderbolts will explode violently, Yang Yi remembers very well that in the afternoon, although the fire at the head of the Xicheng City was full of flames and the fire burned extremely abnormally, there was no strong explosion.

Yang Yi thought about it, raised his hand and wanted to break the wooden stick, but the wooden stick was not burned by the fire, Yang Yi tried several times but did not succeed, and finally had to give up, handed the wooden stick to the iron bull behind him and said: "Tie Niu, break this thing." ”

Tie Niu's expressionless face resulted in the wooden stick, his arms were closed, and he didn't seem to use any force, and the wooden stick snapped and broke into two.

The corners of Yang Yi's mouth twitched, coughed lightly, and took the wooden stick that was broken in two from Tie Niu's hand.

Yang Yi just took the wooden stick in his hand and found that something was "rustling" out of the hollow wooden stick, Yang Yi hurriedly caught it with his hand, but it was some very Chinese powder, because it was dark, he couldn't see what substance it was, a bit like sand but it was a little smoother.

Seeing that Yang Yi was struggling to see, Monkey Jian'er brought the torch closer so that he could see it more clearly.

The firelight was near, and Yang Yi finally saw what the handful of sand-like substances in his palm was.

"It's gunpowder!"

Yang Yimeng closed his palms and quickly took a step back, away from the torch in Monkey Jian'er's hand.

Yang Yi scolded: "Damn! Do you want to ruin Lao Tzu's handsome and handsome face! ”

Of course, Monkey Jian'er knew what would happen when gunpowder met fire, Yang Yi was holding such a large handful of gunpowder powder in his hand, if the sparks on the torch splashed gunpowder just now, Yang Yike would really be disfigured.

"I... How did I know this was gunpowder..."Monkey Jian'er pursed his lips aggrievedly, but he was also a little scared in his heart.

Yang Yi shook his head and said with a wry smile: "I see, this drunken maniac is really good at playing..."

Monkey Jian'er was puzzled: "Your Highness, have you found anything?" ”

Yang Yi rubbed the smooth gunpowder powder in his hand and said with a smile: "I said that this fire is so hot, it turns out to be gunpowder." ”

Seeing that Monkey Jian'er was still puzzled, Yang Yi walked to the side of the charred wreckage of the trebuchet, and explained with his foot: "At the beginning of the year, Lu Yuanliang applied for 300 thunderbolts from me, but I have never been able to find the whereabouts of these thunderbolts, and I didn't say anything when I asked him, but now I understand that these 300 thunderbolts are all in this Tongzhou city. ”

"All here? Didn't you see the military advisor use thunderbolts in the afternoon? ”

"Not a thunderbolt, to be exact, but the gunpowder in the thunderbolt!" Yang Yining said: "The drunken maniac dismantled all of Lao Tzu's 300 thunderbolts, took out the gunpowder inside, and then stuffed them into these hollow wooden tools of the crossbow of the speculation. ”

Yang Yi squatted down and said excitedly: "Now it's all connected, why let Wei Song rob the supplies, why do you keep chasing him but not killing him, and why do you have to drive Wei Song to Tongzhou, the purpose is to borrow Wei Song's hand to give this batch of materials to Zhu Qingxian!" ”

"No wonder when we attacked the city in the afternoon, the drunken maniac only let the equipment battalion smash the Tongzhou army with stones, the purpose was actually to provoke Zhu Qingxian and let him use this batch of materials to fight back, once Zhu Qingxian pushed these trebuchets and bed crossbows onto the city wall, it would be tantamount to setting himself on fire."

Dozens of wooden instruments filled with gunpowder were ignited by Lu Yuanliang's oil bombs, and once the fire burned, it could not be stopped unless everything that could be burned was burned.

Moreover, the fire will only be limited to the city wall, and will not affect the city, if it is directly used to bombard indiscriminately, it will not only injure countless civilians, but also destroy half of the city of Tongzhou, which is difficult to repair before the arrival of Yang Jie's Kyoto army.

Yang Yi had to admit that exchanging dozens of instruments for a complete Tongzhou City was definitely not a loss.

After that, the detailed battle report sent by the statistician made Yang Yi more thorough about the details of the battle.

The Shu army suffered more than 200 casualties, and basically all of them were lost by the hands of Zhu Qingxian's remnants in the city.

And in the same state, the same state master Ji Yan and a large number of Zhu Qingxian's comrades were either beheaded in the chaos, or captured by the Shu army, Zhu Qingxian controlled more than 20,000 Tongzhou army casualties, and the rest all surrendered, the only pity is that Zhu Qingxian's guy saw a bad situation when the Shu army burned Xicheng, and slipped away from the north gate, according to the secret report, Yang Jie, who should have defected to Kyoto.

Yang Yi didn't feel pity, a person who lost his state and abandoned his family, Yang Jie would not look down on him, and it would be good if he didn't cut him down.

In addition, it was not to Yang Yi's surprise, Wei Song's subordinates really had someone who was bought by the Dark Emissary, that is, Li San, who came to Tongzhou to persuade Zhu Qingxian to take Wei Song in.

The whole thing has been in the hands of Lu Yuanliang from the beginning, and it is only a matter of time before he takes Tongzhou, in order to use the minimum price to achieve the maximum return, Lu Yuanliang has spent such a lot of twists and turns, and now it is the time to witness the effect.

It is easy to take the same state, but it is difficult to deal with Yang Jie, who is eyeing the east.
