Kan Ling left overnight, at least Li Shimin didn't know. This is the advantage of being backed by the seaport, Li Shimin's soldiers and horses are relatively small, what is needed is not to let Qin Qiong's 100,000 troops leave Juxian, and the northern line is also guarded, as for the southern line, if Qin Qiong's soldiers and horses all leave, it may be what Li Shimin wants most.

Caozhou, Li Xin was draped in a big hat, looking at the dark night in the distance, Li Xiaogong's camp was still standing there, although there were still many soldiers walking there, the firelight illuminated the entire camp as if it was day, Li Xin could see it clearly even on the top of the city.

Wei Chigong walked over, bowed down and said to Li Xin: "Your Majesty, Cheng Yanjin has sent a letter." Dou Ji'an, who blocked Qin Qiong. ”

"It's Li Shimin, right!" Li Xin interrupted Wei Chigong's words and said: "Only Li Shimin has such a method, and I really guessed it, but unfortunately, Cheng Biting Jin's soldiers and horses were still eaten by him." How is Cheng Biting Jin's situation? ”

"It's not going to be good. Now there are only about 14,000 men left, and most of them are wounded. Wei Chigong hurriedly said: "But I finally met Sun Daochang and the head of the Tan Sect. As he spoke, he handed over Cheng Yanjin's letter.

"Uncle?" Li Xin opened the letter, only to see the contents clearly, and finally sighed: "If it weren't for the master there, I'm afraid Zhijie's subordinates would have lost thousands of people." It's so dangerous! ”

"It's also the luck of Zhijie. If it weren't for where Sun Shenxian was, Zhijie would probably not have the face to see His Majesty. Wei Chigong sighed.

"Li Shimin, tsk, I didn't expect that I played him not long ago, and he also came to give me a look, I and Li Shimin are really a pair of enemies of life and death." Li Xin threw the letter aside in his hand and said: "So many of my soldiers have died in the hands of Li Shimin, this time I am afraid that I also need to give Li Shimin a look, so that Li Shimin can see what Tianwei is." ”

"What does Your Majesty mean?" Wei Chigong said with some concern.

"Li Xiaogong is not Li Shimin after all. Although he has some ability, he is definitely not Li Shimin, his control over the soldiers is not as good as Li Shimin, and the 100,000 army is in my eyes. Moreover, have you found out, there has been a change in Li Xiaogong's camp recently, there is no 100,000 troops in his camp, Li Shimin is probably not just blocking Qin Qiong at the moment, he wants to defeat Qin Qiong, and then deal with me. Li Xin said with a smile: "Wei Chigong." I'm afraid you haven't seen fireworks yet! ”

"Fireworks? I haven't seen it. Wei Chigong was stunned for a moment, then shook his head and said.

"Let's go, I'll take you to see it." Li Xin greeted Wei Chigong and said: "Sometimes, you can't underestimate those outsiders, these guys are eager for immortality, so they make a lot of pills, and sometimes, something interesting will appear." I didn't expect that there would be such people in a place like Caozhou. So I called him in. Li Xin said as he walked.

Wei Chigong behind him was secretly frightened, and he followed Li Xin's side. Naturally, he knew what Li Xin was tinkering with during this time, but he never thought that he would really make it up, and if he couldn't get it right, he even made something powerful.

"Here we are." Wei Chihong followed behind Li Xin, under the escort of the Guards. When I came to the Taoist temple in the east of the city, I saw that outside the Taoist temple, hundreds of soldiers surrounded the Taoist temple tightly, and Li Xin and others had not yet approached. The soldiers took a battle posture with spears in hand.

Wei Chigong saw it clearly, and his heart was secretly shocked. Only then did I understand that this place was probably the most elite rebel of the guards of Caozhou City, which showed how much Li Xin attached importance to this place.

"Your Majesty." followed Li Xin into the Taoist temple, but saw that in the Taoist temple, there were also three steps and one sentry, five steps and one post, and the guards were extremely tight. After entering the main hall, he found that there were many people in the main hall, mostly Taoist costumes, who were besieged together, Wei Chigong walked over, but saw that these Taoist priests were rolling straight cylinders and stuffing some soybean-sized particles into the paper tube. He looked at these small particles curiously, but shook his head, these small black particles, there was nothing strange.

"There's charcoal powder, iron powder, gold powder, or silver powder, which is wrapped in gunpowder, and once it's sprayed into the air, it glows in a variety of colors." Li Xin walked to the side, pointed to the other side, but saw some small wooden handles, there was a long cotton thread in front of the wooden handle, which was connected to the wooden handle, and said, "Do you know what this is?" ”

"I don't know." Wei Chigong shook his head and said.

"Grenades. I called him a grenade, but I don't know how powerful it can be, so it's okay to scare the other person. Li Xin said with a smile: "No way, I know some things, but I can't make them, I hope that those people in the Horror Mountain Villa can make them in the future!" At the moment, these things can only be used for fun, and then they are scary. ”

"This, the minister really doesn't know." Wei Chigong touched his head and said.

"Let's go, let's see." Li Xin asked people to take a paper tube, about a zhang long. Then he took a small wooden handle grenade and walked out and came to the front of Zixiao Palace.

"Bring the fire fold." Li Xin beckoned the guards around him.

"Your Majesty, let's let someone else come!" Yu Chihong said with some concern.

"Don't worry, it's just for scary." Li Xin smiled and lit the fuse of the paper tube, only to see a flash of light, the paper tube did not move at all, Wei Chi Gong was about to speak, suddenly there was a loud noise, a white, yellow, blue light rushed out, suddenly burst out in the air, and then, with another light sound, a light burst out in the air again.

"What's going on?" Yu Chihong was already stunned by all this in front of him.

Li Xin smiled and threw the paper tube in his hand aside, but there was a mysterious smile on his face, this kaleidoscope is actually very simple in principle, gunpowder, iron powder, gold dust, etc., gunpowder is very simple to make, as for various colors, it is even simpler. When the hard wood charcoal powder or iron powder is put into the gunpowder, some particles are not completely burned out after combustion, and when these ejected particles meet the oxygen in the air, a second combustion reaction will occur, resulting in different colors and a certain brightness, which becomes fireworks.

Li Xin can know this, because in winter, burning charcoal in the study, sprinkling some gunpowder and iron powder into the charcoal, and producing some light, Li Xin has inspiration, and this is the appearance of the kaleidoscope in front of him.

It's a pity that although it was made, because of gunpowder and technology, it can only have a few colors, charcoal burning can produce a golden yellow light, but iron powder is a blue light, and then gather those Taoist priests and Caozhou City experts to make a kaleidoscope of suggestions, Li Xin believes that these things are not only used to decorate the night sky, but more importantly, they can produce chaos, which is what Li Xin needs most, chaos can allow him to lead a large army into the enemy's camp and expand the results of the battle.

"That's a little dangerous." Li Xin looked at the wooden-handled grenade and said, "If you don't get it right, you will hurt yourself, and after igniting it, you must throw it out immediately, otherwise you will hurt yourself." ”

"Your Majesty, let the ministers come." After hearing this, Wei Chigong immediately said happily.

"Then you come." Li Xin handed the grenade in his hand to Wei Chigong and said, "Come, light it for him." ”

"General Wei Chi should be careful." After the guards around him lit the grenade, they saw the fire pots flickering, and then a loud roar came from their ears.

"Throw it out."

Wei Chigong was startled, and hurriedly threw the grenade in his hand, only to hear a loud noise, smoke and dust in the distance, Yu Chigong couldn't help but block in front of Li Xin, and said, "Your Majesty, be careful." ”

"It's fine." Li Xin swept away the smell of sulfur in front of him with his right hand, and walked a few steps forward, but saw a small pit the size of a fist in the distance, but the surrounding flowers and trees were damaged, and there were holes of all sizes on it, and the surrounding steps were in a mess.

"Good stuff!" Wei Chigong smacked his mouth and said, "This kind of power is a little smaller." Far less powerful than Xiangyang at the beginning, the minister heard that the general had blown up the Xingyang city wall, presumably because of this. ”

"It's also this, but there is still less sulfur around us, otherwise, we can make explosives packs, but these things are used to scare people, as long as there is chaos in Li Xiaogong's camp, we can take the opportunity to rush into the camp, no matter how Xu Shiji set up the camp at the beginning, we can't help this chaos." Li Xin said indifferently: "And if that kaleidoscope touches a tent, it will still burn, do you think Li Xiaogong's camp will withstand this kind of burning?" ”

"Don't say it's Li Xiaogong, even the ministers are the same." Wei Chigong nodded and said. Humans are afraid of things they have never seen before, and gunpowder is one of them. Although it is only the simplest and most primitive gunpowder, it is also a sufficient deterrent.

"So I'm ready to do it to him." Li Xin said with a grim face: "How Li Shimin deals with Cheng Biting Jin, then how I will deal with Li Xiaogong." If Li Xiaogong had 100,000 people in the camp at this time, then we would have earned. ”

"There are no 100,000, there are 70,000 or 80,000, if Li Xiaogong only has 40,000 or 50,000 people, he will not dare to stop His Majesty." Wei Chigong clenched his fists and said, "Your Majesty, when will you attack, the minister will be the vanguard." ”

"Tomorrow night. I still have to wait to go back to Chang'an for the New Year! Li Xin looked at the moonlight in the sky and said: "The sky is full of stars, it is just the time to attack, I very much hope that Li Xiaogong will not let me down, let me fight fiercely." ”

"Minister, let's arrange it." Wei Chigong said very excitedly, he has been aggrieved for a long time, just waiting to follow Li Xin to take revenge, Yu Chigong is advocating attack, he has never been trapped in Caozhou like this, now that the opportunity has finally come, how can Yu Chigong give up?
