Walk through the secluded courtyard of Old Man Hua until you come to the door. Seeing that the door was half hidden, Xiao Han paused for a moment and pushed the door in.

It's rare that Old Man Hua isn't writing today, looking at the closed window at his desk in a daze.

"Master? Master? Xiao Han walked behind the old man and called him softly.

"Who?" Old man Hua turned his head sharply, and found that Xiao Han was behind him, so he breathed a sigh of relief, got up and greeted: "Xiao Han, why are you here?" ”

"Hey, hey, come and see you!" Xiao Han looked at the old man's preoccupied appearance, snorted, dragged a stool casually, and sat next to the old man.

"Come and see me? That's not right! You have nothing to do but go to the Three Treasures Palace. The old man looked at Xiao Han suspiciously, obviously not believing Xiao Han's words.

Being poked on the spot, Xiao Han smiled embarrassedly, reached out in his arms, took out the plan he had just written, and handed it to the old man: "I still can't hide it from you, master... Isn't this me going out! You're always at home, just take care of my apprentice! Here are some of my arrangements, to you I am the most assured. ”

The old man didn't take the things handed over by Xiao Han, but stared at Xiao Han and said solemnly, "What?" This time, I'm not going with you? ”

Xiao Han smiled and replied, "Master this time, don't run away." When you are older, these things, let us juniors go! You can write at home first, even if you have time to go out to visit friends! You really don't have to work so hard. By the way, I met Mr. Sun Simiao a while ago, he is very close to here, in your spare time, you can also find him and exchange medical skills, Sun Daochang is a very good person. ”

Old man Hua shook his head, Xiao Han's words of relief were of no use to him. As you live older and see more of the world, it is naturally difficult to be comforted by the words of others.

Stretched out his hand to take the paper, and gently put it on the table without being in a hurry to look at it, Old Man Hua sighed, and asked Xiao Han again: "Years ago, didn't you plan everything?" Stay at home with a muffled voice, and let others do the things that fight and kill! Why did you suddenly change your mind now? It's not that the master doesn't want you to make a contribution, but you really don't fit into the battlefield. ”

Xiao Han smiled bitterly, the corners of his eyes were a little moist, in this strange and familiar world, Old Man Hua is definitely the person who cares about himself the most, no one can compare!

Perhaps, the two have not been together for too long. Even if they live together now, the two don't have much time to see each other. But Old Man Hua is really like Xiao Han's father, silently paying attention to himself, thinking about himself everywhere!

Raising his head, Xiao Han said slowly: "Master, what happened before was my wishful thinking... A few days ago, I suddenly thought through: people who want to live in peace often live restlessly! A great man once said that fighting with the heavens is endless. Fighting the ground is a lot of fun. It's fun to fight with people. I don't have the courage of him, but I'm afraid that if I don't fight now, I won't even have a chance to fight in the future! ”

"You're going to strengthen your position in the military?" Old man Hua frowned and asked, worthy of the person who knows Xiao Han best! From Xiao Han's rambling nonsense, he still keenly found his most fundamental meaning!

"Yes!" Xiao Han didn't deny it, nor was he surprised, he simply admitted it.

Old man Hua nodded, and asked again, "Is there a suitable person?" ”

Xiao Han pondered for a moment before he said, "There are three people, I want to see them as soon as possible!" I also want to share a little bit of the grace of knowing it. ”

"Good!" Old man Hua slowly put away Xiao Han's plan, "Since you have made a decision, master, I can only wish you a safe journey, rest assured, I will help you take care of it at home!" ”

Xiao Han got up and bowed deeply.

Xiao Han's plan was actually written in three copies, Old Man Hua was the most comprehensive here, Zhang Qiang had one, and Master Cao also had one.

Zhang Qiang also wanted to be with Xiao Han at first, but Xiao Han refused politely, the second lady had a big belly, and he really couldn't bear to let Zhang Qiang go on an adventure with him.

The day of the expedition is getting closer and closer, and the laughter and laughter in the Xiao family's Zhuangzi have disappeared, and Uncle Stunned leads a few men to practice in the open space every day, not only to pick up the martial arts that have been slackened these days, but also to be familiar with the new weapons equipped in the industrial zone.

On this expedition, Xiao Han only brought five of them, plus Xiao Dong served by his side as a personal soldier, and none of the others were brought.

I was so reluctant to go, he also wanted to go, but because he was not clever enough and his martial arts were not enough, he could only stay at home and watch them busy with tears in his eyes.

Xiaodong is very busy, very busy! Master Cao got so many strange things out of nowhere, equipped him with a lot of brains, and asked him to use them skillfully!

It's inhumane! If you don't practice well, you won't even be able to eat! Xiaodong feels that his bones are in * every day, and he can't sleep at night when he hurts, and no one has come to help talk......

Uncle Zizi came over to see it once, and as soon as he saw Xiaodong raise his hand, he shot a net out of his sleeve.

I don't know what material the net is made of, and it's hard to cut it with a knife! Even if an absolute master is covered by this net, it will be difficult to break free for a while.

Not to mention that there is also a device on the other arm that can shoot steel needles as thin as cow hair, and I don't know how many dense steel needles there are, and the blue needles don't look like good things!

After reading this, Uncle Zizi didn't seem to say anything and turned away, maybe he said it? Let Master Cao practice Xiaodong to the death?

Since that old man saw Xiao Han design the chain with his own eyes, his interest in this magical Hou Ye has increased greatly! After making the chain, he came to ask Xiao Han a lot of things.

The questions he asked were very miscellaneous and covered a wide range of topics, some Xiao Han understood, some knew nothing, and some didn't know anything!

However, Xiao Han's more than 1,000 years of knowledge is by no means in vain. No matter what the problem, Xiao Han can comment more or less, and some of the inappropriate ones are directly pointed out, which makes the old bird shocked!

The water hammer was still successfully developed, and Cao Zhushu had already begun to move the steel mill to the river, and as soon as the water hammer was successful, he began to take over the manpower to build.

Because it is a new technology, the first water hammer is not too heavy, five or six hundred pounds, but even so, it is much stronger than a hammer with human power! What's more, it can work around the clock without any breaks!

Xiao Han came over to look at the water hammer, praised its stability, and inspired the bird elder: "Since the waterwheel is so stable, why not modify it a little and connect the bellows as well?" Wouldn't the temperature of steelmaking be even higher? ”

As soon as these words came out, Master Cao shook his head! Old Bird sighs! The craftsmen around were dumbfounded!

Hou Ye only stood here for a cup of tea! You can design something so practical! Could it be that this is what the ancients said, a peerless genius who draws inferences from one another? Compared with one, these people are simply wine bags and rice bags!

Guilt and shame are more motivating than pride! In addition, the transformation of the bellows is not difficult at all!

In one day, red-eyed craftsmen made several! In order to maximize the use of water power, the bellows specially transformed by the poultry are as large as the original three or four, and they can hardly be pulled a few times with manpower alone!

In order to be able to supply air continuously, a steelmaking furnace must be connected to at least two bellows!

Filled with newly made coke and activated the bellows, the original orange flame turned pale blue. The iron ore was thrown in, and it quickly turned into a pot of fiery molten iron, and some impurities that could not be melted were scooped up by the craftsmen with long iron spoons and stored aside.

These might be good things, and they decided to try again when they had a better fire!

But here Xiao Han knows: the current flame is almost the best that can be achieved in this era! If you want to completely squeeze out the energy of coke, you need to blow oxygen, and Xiao Han can't make that much oxygen at all!
