Feihuang Tengda is not interested, but the secret recipe must not have the courage to leak it, Li Su did not even dare to ask for money this time against his nature, he just knew how sensitive gunpowder is, since he got it out and was seen by the court, he believed that this thing would have nothing to do with him from now on, and mentioning money would make the court have a kind of taboo that was inexplicable. ∮ ∮ ∮ ∮ said, www.

Niu Jinda was full of praise for the small clay pot, which obviously suited his taste.

"Good baby, why are you so awake?" Niu Jinda patted him on the shoulder as soon as he was happy, Li Su was already on guard, and he flashed quickly, but he didn't pat him.

After a few dry laughs, Li Su explained: "Boss, if this thing reaches the maximum damage on the battlefield, you must find a few guys who are not afraid of death, pause for a breath after lighting the fire, and then throw it out when the lead is about to burn out, throw it higher, it is best to explode in the sky above the enemy's pile, the broken iron inside is more domineering than gunpowder, and a large piece of death will die." ”

Niu Jinda is a military general after all, and he understands the things that kill people, so after thinking about it for a while, he immediately understood, and his expression became more and more shocked.

"How much can this thing do in a day?" Niu Jinda asked excitedly.

"The material is the key, if the material is enough, how much there is, the process is very simple, call more people to help, two or three days to make enough for Songzhou to break the city."

Li Su didn't say much, if the grenade is the primitive process of ignition now, it will indeed be more or less, and its principle is like doing artillery battles, in the previous life, the countryside was full of artillery handmade black workshops, and all the output of a day was ignited, which was enough to make several mushroom clouds rise in Songzhou.

As for the firing of grenades in later generations, as well as the lead delay device...... Li Su can't do it at all, he will only do artillery battles.

"Good! Ben Shuai will find dozens of awakening people to help, you teach them, I will immediately ask His Majesty to give them a promotion. Niu Jinda nodded heavily.

Li Su understands the meaning behind the promotion, if nothing else. I'm afraid that these dozens of people will not be able to see the light of day in the future, and it sounds good to say that it is the core work of a highly classified unit, and it is not good to say, well, it can be regarded as a labor prisoner with an official position, and it is the kind of life imprisonment. However, the rewards given by the imperial court to the children of his family must be very rich, and within three generations, they may be able to withstand the peripheral circle of the powerful.

One is willing to fight and the other is willing to suffer, I can't tell whether it is good or bad, and if I change the king's pile, I may happily agree, and exchanging my freedom for the future of the two brothers in the family is a very cost-effective deal in his opinion.

If it were Li Su himself, he would have made a limited-edition collector's grenade and blew up the black workshop.

However, Li Su did not plan to recommend Wang Zhu, he did not know what Cheng Dù Li Shimin would attach importance to the secret recipe of gunpowder, and if he attached great importance to it, Wang Zhu came into contact with it. There is a real possibility that I will not see the light of day in this life.

"There are a few things you want that are not easy to find, but it doesn't matter, there are many people under the command of this commander, and the war will be simply truceed these days, and half of the cavalry battalion will go out to collect these things, and you will definitely be able to gain a lot in three or two days......" Niu Jinda squinted and looked at the towering Songzhou city wall in the distance, and his hazy face became extremely relaxed.

"Make a batch first, and then attack the city in a few days. Try how powerful this thing is, if Songzhou can recover it. Little baby, you should be the first to take the lead. ”

**********************************************************

Li Su felt that he had unconsciously walked on the road to promotion to the rank of knight, and he was getting faster and faster, so high that he couldn't stop at all.

After all, I was reluctant, but I didn't regret it. Just like the previous treatment of smallpox, this time it is also for the Wang brothers. It's a bit hypocritical to say great, it's just that he treats them as friends, and he happens to be able to solve the predicament of these two friends, and it's as simple as that.

Sometimes I can't help but envy the Wang brothers, how many wooden fish they broke in their previous lives to let them know such a perfect friend. On the contrary, I must have done a lot of immoral things in my previous life, and I only worked so hard in this life.

Niu Jinda was very efficient, and it didn't take long to collect all the materials he needed, and he found dozens of soldiers from the army, and there was even a small official with the army.

Everyone looked sad and honored, looking at Li Su's expression as if he was paying attention to a martyr's monument, this kind of look made Li Su very unhappy.

Niu Jinda was kind, and when he picked people, he probably told them about the treatment in the future, and they obviously made a prudent choice before they could stand in front of Li Su.

Niu Jinda mobilized guards to surround the workshop, and those who dared to come forward to watch were not only driven away, but also had to eat military sticks.

Li Su explained the method of black powder to everyone in detail, and there was no need to tell them the principle, because Li Su didn't know some of the principles, and he just relied on the gourd to draw a scoop.

It's not something too complicated, you can understand it as soon as you explain it, under the guidance of Li Su, everyone made the first finished product by hand, and Li Su didn't bother to take care of the rest of the things, and shouted a few slogans in a fake appearance, such as dedicating his life to Datang imperialism, etc., and then quickly quit the black workshop and ran away.

A group of terrorists inside make explosives, which is equivalent to a powder keg that can explode at any time, in case something happens, such as a guy with an obvious IQ who wants to recharge thinks the light is too dim, and lights a torch to make a can or something......

…………

Dozens of people started at the same time, the efficiency was very fast, two days of hard work to create more than 2,000 small cans, black and scaring to look at, Niu Jinda was very happy, and warmly invited Li Su to watch the results together, but Li Su categorically refused, and he didn't get close to death.

He was not the only one who was warmly invited by Niu Jinda, and he heard the commotion in the early morning, and it turned out that it was Hou Junji and Liu Lan, the two chief managers, who came/

Li Su pretended to be deaf and dumb and ignored it, hiding in the camp tent to sleep, and not long after, a thunderbolt-like explosion outside the tent scared the defenseless Li Su into a corpse A few times, Li Su turned over and sat up, sighing heavily.

If you can't sleep, go out and join the event.

Outside the handsome tent, Niu Jinda, who had just tried the effect, accompanied the two armored generals and laughed happily, and even the posture was the same when he laughed, they all looked up to the sky and laughed, as if his face was not heroic when he smiled, in fact, it was easy to laugh like this......

"You're Li Su?" Hou Junji smiled and looked at him seriously.

"Back to the Grand Boss. Xia Guan is exactly. ”

"It's really as His Majesty said, it's really my Tang Dynasty boy Yingjie, this thing is domineering and extraordinary, with its help, Songzhou Bike!" Hou Junji laughed loudly, his expression was very bright. He is the general manager of the Midao marching army, although the soldiers are divided into three ways this time, but he has the right to control the three armies, yes, if there is a brave person in the enemy army who can behead the general in a million troops, it is Hou Junji.

Of course, after recovering Songzhou, Hou Junji's credit is also the greatest, so now he is smiling so exaggeratedly.

"We've tried everything. Indeed, as Lao Niu said, he was very domineering, just now we were still saying, to recover Songzhou in the coming day, the three of us will jointly play the first gong for you! Wahahahaha...... "Laughing again."

Liu Lan was relatively silent, and said with a gentle smile: "Fortunately, Your Majesty sent you with the army this time, otherwise we are afraid that we will suffer a big loss in the battle of Songzhou." ”

Niu Jinda laughed loudly, stretched out his hand and hooked Li Su to his side: "The child's family." Don't spoil him, the first merit is to be invited. I'm playing it all by myself. ”

Hou Junji pointed at him and scolded with a smile: "The old man will buy people's hearts, and he will be drawn to your side so quickly, don't be happy too early, Lao Cheng's tricks are more vicious than you and me, and I will treat this little baby as a baby earlier." ”

Niu Jinda grinned: "Your Majesty placed this little baby under Niu's account, naturally it is my person." The little baby has made meritorious contributions, and he has his own Niu to perform meritorious work for him, and he wants you to do more. ”

Li Su quietly watched the three of them arguing on the side, Niu Jinda's attitude was very resolute, and he could only play the gong alone. Hou Junji and Liu Lan couldn't get involved.

After watching it with interest for a long time, Li Su gradually tasted the taste, and the corners of his mouth couldn't help but hook up a chuckle.

Very interesting picture, a few martial artists fight their hearts, it seems that they are no worse than civil officials......

In the end, Niu Jinda became impatient, and shouted: "I have written the chapter, come on!" Hurry up and take my music into Chang'an and present it to His Majesty, as well as those small cans, and send a few with you. ”

The rogue trick came out, Hou Junji and Liu Lan were so angry that their eyes were round, but they were helpless to take him, and scolded him with a fake smile, so they gave up.

Sending away Hou Junji and Liu Lan, Niu Jinda once again beat the drum and gathered the generals to give a military order, make food tomorrow, and attack the city at three o'clock.

After the generals dispersed, Li Su remained in the tent, and Niu Jinda squinted at him: "Is there anything else to do with the little baby?" ”

Li Su straightened his clothes, and suddenly gave Niu Jinda a long look: "Boy, thank Uncle Niu for his kindness." ”

Niu Jindaleng paused for a moment, and his expression became strange: "Just now...... You get the idea? ”

Li Su smiled: "The kid understands." ”

"In the end, it was a young hero who was praised by His Majesty, and it was really extraordinary." Niu Jinda was a little surprised, and then waved his hand lazily: "It's good to understand, you are young, don't mix this kind of thing." ”

"Yes, the kid didn't understand anything."

The question was clueless, Li Su's answer was clueless, everyone was pretending to be confused.

…………

…………

At three o'clock the next day, the Tang army attacked the city for the third time.

There was a strange army in the front army array, a hundred people held horizontal swords, two soft leather bags hung around their waists, the skin bags were bulging, and this hundred people stood behind the crossbow and arrow battalion, each of them twenty steps apart and mixed in the siege sequence.

The war drums rumbled, it was still the crossbow arrows and the stone throwing cart that appeared first, the rain of arrows and boulders in the sky opened the prelude to the battle, and then the low horn sounded, and in the earth-shattering shouts of killing, the soldiers of the Tang Army rushed towards the city wall with the cloud ladder.

The siege tactics were the same as the previous two, and there seemed to be nothing new. The Tibetan generals at the head of the city were nervous for a while at first, but then gradually relaxed, and it was still the old routine of defending the city before, and the offensive and defensive sides worked hard for a long time.

No one noticed that there was a variable in today's siege team that would turn the tide of the battle.
