When people are always forced to a desperate situation or circumstance, they will be anxious to come up with a way, in order to survive for themselves or for others, if they are not in a desperate situation, this method may never come up with it.

Li Su is different, the method of breaking Songzhou was thought of as early as on the march, but he never dared to take it out.

He didn't know what would become of the Tang Dynasty and even the whole world in the future after the Tang army used this method, it was too unpredictable, like a Pandora's box, after opening it, human beings could no longer control it at all, they could only let it spread, Li Su had been hiding it, and he was afraid of this.

How good it is now, everyone lives in harmony, even if it is a war, you and I will shoot it, and the knife and gun are full of uprightness and fairness, and the future will ......

can't care about the future, Li Su looked at the in front of him spitting blood, wiping a lot of tears, he really couldn't bear to see him drag his weak body tomorrow, copying the Mo knife and fighting with the Tubo barbarians, since there is a simple way to win, why watch human lives fill in one by one?

"What's your idea?" Wang Zhu stared at him in disbelief.

"Po Songzhou's method, you don't care, tomorrow will definitely besiege but not attack, you take care of your injuries, I have something to do with the general manager, and I will inquire about the whereabouts of the second child in the afternoon."

Since he had decided to act resolutely, Li Su simply patted his buttocks, threw Wang Zhu outside the camp and left.

After taking two steps, he turned around, took out a piece of muntjac meat and handed it to Wang Zhuan.

Wang Zhu looked at him speechlessly: "It's the chief manager again?" ”

"This time it's different. This piece of meat is very meaningful, not for reward, but for me to steal from the handsome tent. ”

Wang Zhu sighed: "You think I am like this." Can you still nibble on hard dried meat? ”

Li Su was right when he thought about it, so he smiled and said: "In the evening, I asked the Chinese military man to boil some meat porridge and send it over, so he is also an eight-grade official, and he should open a small stove for me...... You can keep the dried meat, and take it out and gnaw it when the injury is better. ”

The commander of the Chinese army, Niu Jinda had a gloomy face and looked at the generals in the tent coldly. The temperature in the tent dropped to freezing, and the generals stood with their heads bowed. I didn't dare to take a breath of the atmosphere.

In fact, in the past two days, the generals have also offered a lot of methods, such as digging tunnels, throwing fire oil cans into the city, besieging the city and consuming the enemy's food and grass to sit down and so on. These methods were all vetoed by Niu Jinda.

In particular, the generals who proposed the siege method were taken out by Niu Jinda and scolded so bloody.

50,000 people surround a city of 200,000 people, and wait for them to run out of food and grass? What shape of idiot can come up with such a strange idea.

Looking at the group of generals in the tent who hung their heads and didn't dare to make a sound, Niu Jinda felt more and more annoyed, waved his big hand, and shouted: "Get out!" Get out! A bunch of manure-making waste! ”

As if they had been pardoned, the generals hurried out of their tents, looked at each other, and smiled bitterly.

Niu Jinda sat in the handsome tent and sulked alone. But he listened to the report of the guards, and recorded that Li Su, who had joined the army, asked to see him.

Niu Jinda is angry, regardless of whether he joins the army or not. Immediately yelled: "Get out! Missing! ”

The guards outside the tent were yelled at and shook their heads at Li Su.

Li Su naturally heard it, scratched his head and said, "Why is there such a big fire?" Don't want to hear the law of Posong State? I'm going to find the material myself......"

Before he finished speaking, Li Su found that he suddenly rose into the air, and yes, he was picked up by Niu Jinda who came out of nowhere. It's that shameful posture again.

"Chief Administrator......" Li Su was frightened, Niu Jinda's face was even more hideous than the last time he discovered the wonders of the horseshoe. It was as if they were going to eat him alive.

"Little baby, do you have a way to break Songzhou?" Niu Jinda almost touched Li Su's face, and asked through gritted teeth.

Li Suleng paused for a moment and nodded: "Ah, there is a way...... Chief manager, can you put down the subordinate officials first? ”

Niu Jinda put down Li Su, and his bloodshot eyes were still staring at Li Su: "Little baby, there is no joke in the army, and military affairs cannot be joked, do you really have a way?" ”

"Yes......"

Niu Jinda didn't know what stimulation he had received when he was young, and it was difficult for him to trust others, so he pressed step by step: "Can you dare to make a military order?" If your method doesn't work, what about the bento? ”

Li Su knew that according to the normal routine, at this time he should pat his chest and be heroic, for example, if he can't break Songzhou, he should come to see him, etc., from ancient times to the present, the people who said this have never considered the logical flaws in the words, and they came to see him? Who's going to try one? Insincere!

Li Su's reaction was very simple, and he didn't fall for Niu Jinda at all, and said happily when he heard the words: "Excuse me to disturb the chief manager, I didn't say anything to the current official just now, and I said goodbye......

Niu Jinda was stunned, watching Li Su pat his ass and turn around and leave, walking very crisply and decisively.

This is not a routine...... What about the good mention of the head?

"Get back to Ben Shuai!" Niu Jinda roared.

Li Su had no choice but to rub his nose and roll back.

glaring at Li Su hatefully, Niu Jinda's big slap was raised and lowered several times, wanting to slap this kid, but he was afraid that he would be slapped to death......

"Okay, if you don't force you to make a military order, the little baby doesn't dare to gamble with his life, let's talk about it, what is the way to break Songzhou, don't blame you for your mistakes." Niu Jinda's expression eased a lot.

Li Su thought for a while and said, "I need something, if the chief manager can help get it, it won't be a big problem in Posongzhou." ”

"What's that? Just say. Niu Jinda's eyes lit up, and his tone became hurried again.

Li Sudao: "Sulfur, charcoal, saltpeter, small clay pots the size of fists, sharp pieces of broken iron, bamboo pipes the thickness of little fingers, fish glue, well, and...... Eggs, these things, how many get as many as they get. ”

Niu Jinda frowned: "What do you want to do with these?" ”

"Break the city."

"Can these things break a city?"

"Of course, these can't break the city, but they can be broken by combining them together."

Niu Jinda stared at him suspiciously. Li Su looked at him without shying away.

"If the chief manager doesn't trust the lower officials, he might as well think of the horseshoe, four pieces of iron. I can let the Tang cavalry dominate the world. Li Su was not low-key this time, straightened his waist, and showed a bit of arrogance, perhaps, this is his true nature.

Niu Jinda hesitated for a long time, and finally gritted his teeth: "Okay!" Niu will accompany your little baby to mess around, and I immediately ordered people to collect these objects. The army besieged the city and ceased fighting for two days, and if you haven't done it after two days......"

Niu Jinda smiled. "...... It's also Niu's fault, I ask Your Majesty for my guilt, and I have nothing to do with you, little baby. Just let it go. ”

Li Su was moved, and he gave Niu Jinda a long look, and said: "The chief manager is Gao Yi, and the officials are very impressed, so I won't collect money from the court this time......"

After speaking, Li Su raised his head, opened his cute big eyes, and waited for Niu Jinda to show the same touched expression on his face.

――I didn't wait.

This is also a guy who doesn't play by the routine.

…………

…………

After Li Su withdrew from the tent, Niu Jinda really issued a military order and sent people to collect the things that Li Su wanted in nearby villages and counties. As many as there were, at the same time ordered the army to rest and recuperate, and besiege Songzhou without attacking. and took his personal guards to go to Hou Junji and Liu Lan's department to explain the reason for the incident.

Trust in Li Su is one thing, but trust cannot reach this point, and it is impossible for Niu Jinda to truce for two days just because of the words of a hairy child.

The main reason is that the Tang army really can't come up with a way to break through Songzhou, and the military reports of Chen Qing are still on the way to Chang'an, and there will be no reinforcements within a month. Tubo defended the city and won two games in a row, which was the time when the momentum was at its peak. No matter the time, place and people, it is not suitable to attack the city again, and all the elites brought out are the elite of the children of Guanzhong, and the three chief managers can no longer use their lives to fill this bottomless hole.

As for Li Su's method, Niu Jinda can only say that he will just give it a try, if he says that he can break a city by getting something novel, what else do they want these soldiers to do who were born and died?

The army was mobilized to find some things, and the efficiency was very fast.

In the evening, several teams of cavalry entered the camp from outside, and all the things that Li Su asked for were found, and there were quite a lot of them.

Eggs, bamboo tubes, broken iron clay pots, these things are easy to find, saltpeter and sulfur took a little effort, fortunately, there are awakened people in the Tang Army soldiers who went out to find things, knowing that saltpeter and sulfur are not easy to find, but there must be Taoist priests in the Taoist temple, these Taoist priests are fierce people, in order to refine the elixir of immortality, what messy things dare to stuff into the mouth, but also persuade others to stuff it into the mouth, saltpeter sulfur These things are the necessary things for their alchemy.

Luckily, there is a Taoist temple near Songzhou City, and there is more than one, this year thanks to the blessing of Lao Tzu, Taoism has become the state religion, and the popularity rate of the people is still very high. Because of the war in Songzhou, the Taoist priests in the Taoist temple hurriedly rolled up and ran away, as for the worthless things such as saltpeter and sulfur, they were decisively given up by the Taoist priests, and the soldiers found it without much effort, and got a few big baskets to carry it back.

…………

Things were piled up in front of Li Su, and Li Su sighed.

Do it, be diligent now, and have a happy life of laziness for a lifetime in the future.

How do you make a grenade? Beat the eggs first, don't use the yolks, and leave only the egg whites.

Then the gunpowder was dispensed out, and the gunpowder was actually inadvertently invented by the terrorists who refined the elixir, and it was recorded in a book called "Taiping Guangji" that as early as the early years of the Sui Dynasty, a man named Du Chunzi went to visit a hardcore terrorist and drug addict...... Well, old alchemist, in the middle of the night, I suddenly heard a loud noise, and the entire roof burned inexplicably, and what could be both loud and burned, there was no doubt that it was gunpowder.

Fortunately, although the alchemists invented gunpowder, the most powerful ratio has never been found, otherwise if they really find it, a mushroom cloud will rise every other way in the land of China, making people confused whether they are flying to the fairy realm or misfired, which is very confusing to the public......

Regarding the ratio of black powder, it was basically known to everyone in later generations, and after Li Sumo memorized it, he began to mix gunpowder.

Saltpeter, charcoal and sulfur were all crushed and crushed into powder, one and a half charcoal, one and a half sulfur, and then seventy percent saltpeter, and the powerful black powder was born.

Then use egg white to make it granulated, keep screening, too large particles do not want, too small do not want, the size of a grain of rice is just right, and then put it into a small clay pot, by the way decorate sharp pieces of broken iron to increase the lethality, bamboo pipe insertion in the middle of a lead, soil and fish glue seal......

The rudimentary version of the Datang grenade has been completed.

Li Suding looked at the small black clay pot in his palm, his mood was very complicated, he opened Pandora's box with his own hands, and released a terrible devil, the world ...... After all, the world is different from the previous life.

ps: There is one more ...... (To be continued)
