On the third day, Cheng Hong looked at the rows of iron-cast grenades in front of him, picked up a spit and said: "As long as this thing is enough to charge into battle, throw the grenade down, and the iron man will blow it up for you!"

Li Tai squinted his eyes and looked at Cheng Hong bragging to Li Chengqian there: "What are you blowing!" It's not all made by me! ”

Cheng Hong rarely blusheed: "The process is not important!" It's the results that matter! Plus, that's not the best way to use gunpowder! This thing is bundled into a bag of explosives, and it is piled up under the city gate and city wall, and when the time comes, 'boom', no matter what the city wall is, just lie down!

There is also Baoqi's side to open the road and blow up the mountain or something, as long as it is used well, it is faster than 180 people to dig it! It's second only to the steam engine! ”

Li Chengqian looked at it for a long time and picked up one: "Just this iron bump?" Ignite and throw it to kill a bunch of people? Have you tried it? Let's try it first! If it becomes the Emperor, go to the Emperor! ”

"Let's go! Try it in the mountains! Cheng Hong picked up the two and pushed Li Chengqian out! Why use a hug? Isn't it! Li Tai, the first batch of cast grenades, thought that the bigger the better, but this grenade turned out to be the size of a lead ball!

Don't worry about throwing you! Cheng Hong had no choice but to lengthen the lead and use it with mines! The lead ball is like a grenade, and a total of ten are cast! Then Cheng Hong found out and began to change it to the size of a fist! For this reason, Li Tai was a pity for a while!

The servants were adding a Zhang Yuanli and walked to the hill behind! Chatter along the way! Li Chengqian didn't believe it, Cheng Hong patted his chest and assured that Li Tai would be suspicious here! As for Zhang Yuanli, ignore him! Since Cheng Hong saw Zhang Yuanli the day he saw him, he hadn't seen any expression on his face!

Cheng Hong found a dead tree and stuffed the grenade into the tree hole, but fortunately, the hole in the dead tree was big enough! Cheng Hong asked them to retreat to about fifty meters!

Zhang Yuanli also wanted to take a closer look, Cheng Hong hurriedly drove him away, this is not a joke, it will be fun to blow up Li Er's personal guard leader into two sections with a "boom"!

Cheng Hong spread the lead more than three meters out, and blew it with the incense! It's like lighting a cannon when you were a child! After lighting it, I watched the burning of the lead "snort" and threw the incense head, and ran backwards like flying!

The lead has not burned to the end, and Cheng Hong has already run to Li Tai and them closely! Jumping into the pit and Li Chengqian, they looked at the large grenade in the hole in the tree! Zhang Yuanli stood on the dirt slope and stared at the ...... without blinking.

"Boom!" A bolt from the blue! A sound scared the servants! Li Tai sat directly on the ground! Zhang Yuanli Zhang Yuanli clasped his ears, and the horizontal knife came out of the sheath and slowly went over there!

Cheng Hong came out from under the dirt slope and looked: He! The dead tree was blown down! The grass and trees with a radius of about five meters seem to have been blown by a whirlwind!

The four of them approached, and the dead tree exploded in all directions! The grenades are full of broken nails! The trees that are close to each other have been broken with a lot of nails! Deeply embedded in the tree! Zhang Yuanli searched around and found that the farthest broken nail nailed to the tree was twenty-five steps away from the broken tree!

Zhang Yuanli was scared after reading it! At first, he wanted to see it closely! If this can't be crumbled into a sieve in front of me?

After a cold war, he hurriedly asked Li Chengqian for instructions: "His Royal Highness the Prince, this is an important weapon of the country, and it should be reported to the Holy God immediately!"

Li Chengqian and Li Tai were dumbfounded as they looked at the effect caused by a grenade in front of them! "This! This! Is this really made by us? Li Tai looked at Cheng Hong!

Li Chengqian calmed down: "Report to my father immediately!" Also, Fourth Brother Cheng Hong took the remaining grenades and recipes and followed me into the palace! "Four people and four horses, even the guards didn't bring the formula, Zhang Yuanli carried a shot put-sized grenade into the palace!

The rest is in the lab! Because Cheng Hong said: "Take so many in case you accidentally blow up one and it's over!"

Here Li Tai said: "Blow it up!" Anyway, we all made it out, and if you fry one, you can say that you can't get eight! ”

Cheng Hong......, Li Chengqian......, Zhang Yuanli ....... Otherwise, there is always a short circuit in scientific research! Smart as Li Tai still has a short circuit!

Here, the sweetwater shop of Li You and Li Su brothers is open! In the past two days, Cheng Hong has seen that the two of them have changed well, so he doesn't train them so much! In addition, Cheng Hong has been busy with trains and explosives in the past two days, and he also has an indulgent attitude towards them!

Let's see what they can do! Unexpectedly, the two of them entered the steel mill once, and actually proposed to Cheng Hong to open a sweet water shop at the door! Cheng Hong was impressed with them!

Whether it works out or not, it's good to have an idea! I have to support it! The two brothers took Cheng Hong's strips to the door of the steel mill and chose a place near the account room, built a shed, and put a few small horses and small tables according to the appearance of Xiaodouzi's meat and bun shop!

Why this place? Li Su has experience! He worked in the steel mill to calculate the accounts! He knew that all the sweet water he could buy was near the bookkeeper!

The stewards of the team leader, the merchants, the ones who are waiting to receive the goods, the ones who pay the money...... All line up here! That's why they chose this place as the store!

The two of them boiled four buckets of sweet water and carried it to the shed, and the store was opened! At first, I yelled twice, but then I didn't have to shout at all!

A group of people lined up and were hungry and thirsty, and at this time, Li You and his brothers came over with sweet water, and they still shouted at you? It's a big bowl, and it's not expensive! This thing is not wine, so I'm not afraid of mistakes!

By the way, sit on the mazaar and rest! I've been standing here for a long time, and my legs are numb!

Four buckets of sweet water were sold out in less than an hour! Li You saw that this was too easy, and he wanted to go back and boil it up!

Li Su looked at it: "No need! I've drunk almost everything I wanted! Besides, if we're waiting for the sweet water to come out, it's already dark! Who do you sell? Let's boil an extra bucket tomorrow!

Besides, we've got to find someone! We're definitely not going to do it! According to the plan, Ergouzi, Zhao Shishi, Zhao Liuya, let's get up early and mix the sweet water raw materials, so that Zhao Liuya can watch the fire! After boiling, let's bring it over with Zhao Shishi and the two dogs! ”

"Good! Listen to you! Li You nodded!

I have to say that Li Su has a good business vision! If it's really boiling, most of it won't sell!

The two of them counted the copper coins over and over again! A total of 217 texts, firewood, honey, dried dates...... Earned at least one hundred and eighty wen! This is the first money for the two of them! The two of them were so excited that they couldn't wait to tell everyone right away!

After going back, the two of them found that except for Wu Erya and the two big maids, the rest of the people in the courtyard were gone!

It seems that the third brother and Cheng Hong have been studying what eggs are going on these days, and it is estimated that they have studied it and reported it to their father!

But~ we also want to report to our father! We're making money! We're not trash!

So the two waited for Li Tai and them to come back, so that they could share their joy, and the two waited until they saw Li Tai and Cheng Hong come back......
