On this day, Ankang and Anfu came home very late.

It's not because there are a lot of things, but because Song Qiushuang won't let people go at all.

In the end, Ankang was really helpless and gave Song Qiushuang some Force cores.

Only then did Song Qiushuang calm down her inner dissatisfaction.

Ankang now has a large number of Force Cores in his hands. It's all made from the animals in Gushan City.

After the battle of Gushan Castle, Ankang dragged the corpses of some highly spiritual animals into the small universe and froze. After returning to the city, I refined some of it for the students to enjoy. Some of them were refined into Force Cores.

Originally, Ankang planned to give all the Force Cores to the teenagers, but he dismissed the idea. Force cores are rarer, so it's better not to distribute them evenly. Wait until the next critical time to give it to those who are making faster progress.

The crowd gathered firewood and the flame was high.

The process of building a steam engine was faster than expected.

Although it is said that the number of steam engines to be built this time is ten times more than the last time, after all, Ankang is just to complete the task assigned to him by the system, so he builds a simplified version of the steam engine.

On the first day, after explaining the drawings clearly, explaining the process, and assigning tasks, the coppersmith shop was asked to rush to work overnight that night. By the next day, the main components had been built.

Mr. Shi was a little mentally stimulated because of the rejuvenation. After a night's rest, he came to the school full of energy.

He was too busy meditating yesterday to bother with building a steam engine. Mixed up with interest today.

Although Mr. Shi mainly teaches liberal arts, he is also a technology fan, and when he has nothing to do, he makes some furniture, farm tools and the like out of wood at home. It is said that he also met the founder of the Mo family, the master of wood art Mo Zhai, who was as famous as Lu Ban.

When Mr. Shi saw Ankang's steam engine for the first time, he was amazed, saying that Ankang's self-walking carriage was more sophisticated than the wooden kite that Mo Zhai made that could fly in the sky, and said that he would write a letter to Mo Zhai.

Now these students are going to start building steam engines again, and Mr. Shi will of course have to get involved. He also said that he would pay for investment, but Ankang did not take his money.

Mr. Shi came to the school early. He did not arrange classes, but threw himself into the great cause of building a steam engine with his students.

Before the boys arrived at the school, they went to the coppersmith's shop and brought back all the parts they had made. Began to assemble the steam engine in several groups in the school under the command of Ankang.

Don't look at these steam engines are much lighter and smaller than those built by Ankang before, but the precision requirements for components are actually higher, and the difficulty of manufacturing is not low at all.

Previously, the pipes in Ankang's steam engines were formed directly in the coppersmith's shop. Now when I take it back and assemble it, I have encountered the problem of how to connect it tightly.

If it is placed in modern times, it is certainly not a problem. Both pipes are shaved out of threads, one pipe is used as a screw, the other pipe is used as a nut, and a waterproof material is added in the middle to screw the two pipes together.

That's what the faucet with the water pipe installed does. Very simple.

But now it's 2,500 years ago. It is possible to cut threads into the copper pipe, but it is simply not possible to make the screws and nuts fit tightly.

Therefore, in order to solve the problem of pipe connection, flanges are added at both ends of each pipe, and then the two ends of the pipe are tightly connected with cowhide. It's rough, but it's just a good thing to do.

In solving these small problems, Ankang realized that there were two problems that needed to be solved in order to make technology develop. One is the material and the other is the processing equipment.

In the future, we must solve these two problems first.

Despite the difficulty of the problem, it took a whole day to build all ten steam engines.

Ankang looked at the fruits of his labor with satisfaction, and happily listened to the broadcast of the completion of the task in his head——

"Congratulations to the host for completing the quest and getting a new ...... Gain new skills...... Acquire new skills...... New Skill ...... Skill...... Yes"

I'll go! What's the situation?

"System, what's wrong with you?"

There was a dead silence in my head.

Ankang checked his attributes, and in addition to the Force, there are only two skills in the [Skill System] column: Fire and Healing, and there are no other new skills.

This system can't be a crash, right?

Ankang was very depressed. If you don't die sooner or later, you just crash at this time.

Helplessly, Ankang was instructing the teenagers to start one of the steam engines when he heard a sentence in his head: "The system reboot is complete." ”

The system is finally working again. An Kang let out a long breath.

This system is his plug-in as a savior. If something goes wrong with this plug-in, it's really damning.

After a while, a task interface appeared in front of Ankang's eyes-

【Mission】Build 10 steam engines

Bonus: A new skill

How is this still the task?

Ankang asked in his head: "System, system." I've done that. Now it's time for the quest rewards. ”

The system mechanically replied: "What was done before doesn't count." Whenever the system restarts, the current task needs to be redone. ”

I'm going to go!

In order to build these ten steam engines. My classmates and I have almost emptied our homes. You're asking me to do it all over again now?

Hey? Wouldn't I take these ten steam engines apart and reassemble them once?

When Ankang was proud of his wit, the system explained again: "Reassembled doesn't count." The task was to build ten more steam engines in addition to the previous ten steam engines. ”

When Ankang heard this, he shouted "I am also painful", and died. Eight out of ten years old.

A generation of saviors was by the system like this...... How is this possible?

Even if Ankang cries to death, he can't get so much copper.

So be it for this task. More on that later.

Mr. Shi and the teenagers cheered outside the school. Ankang was secretly sad alone in the school.

At this time, a man came in quietly.

An Kang turned his head and was stunned.

The man who came in was a very handsome young man.

Ankang always felt that this young man looked a little familiar, but he couldn't remember seeing him somewhere.

"Big brother, what are you looking at me like this?"

As soon as the man spoke, Ankang finally knew who he was. Fat man Anfu.

"Ah Fu, why did you cast the [Charm] spell again?"

"[Enchantment] spells? I didn't. Anfu went to his seat and picked up a copper fan as a mirror to look at, and he felt incredible, "Huh? ”。

Anfu's [Charm] skill is the same as Xiao Liu's [Invisible] skill, and the time for the effect is very short. After a while, Anfu returned to his original appearance.

An Kang asked, "You cast a spell and you don't know it yourself?" ”

Anfu shook his head.

An Kang couldn't help but fall into deep thought when he heard this. This Anfu seems a little abnormal.

When he used the [Wind Resistance] skill, he was floating in the sky, and he didn't know it. Now when he casts [Charm], he has a different appearance, and he doesn't know. What's going on?

And that's not all. Recently, when he used the Force Launcher on Anfu, he found that Anfu used to blindly attract the Force, and during this time, he actually pushed the Force he attracted back again.

Ankang asked Anfu what was going on. Anfu also shook his head and didn't know. Absolutely unaware of what was going on.

In addition to Anfu, Mr. Shi's rejuvenation is also an alternative, and the other is Song Qiushuang.

She's bewitching again.

When An Kang and the other teenagers arrived at the courtyard of Song Xiayang's house at night, they heard a "bang" sound inside. When I walked into the wing, I saw Song Qiushuang set up an archery target in the wing, and then threw the bricks in his hand to smash the target.

Practice ranged attacks, there's nothing wrong with that.

Ever since she learned to attack from a distance, she's been practicing precision.

In the last battle of Gushan Castle, she threw bricks several times and almost smashed herself. It's really about practising.

The reason why everyone feels abnormal is that the brick can magically return to her hands after being thrown. In other words, after she uses her earth-based skills to evolve a brick, she can use it an infinite number of times.

Although Song Qiushuang's elder brother Song Xiayang has better wood skills than Song Qiushuang, he also has more Force than Song Qiushuang. But the javelin he threw was not returned. With each javelin thrown, the Force is reduced by a part.

With Song Xiayang's current level of Force, he could only throw two hundred javelins at most, and his Force would be exhausted.

And Song Qiushuang only needs to use the Force when evolving the bricks, and the rest is to rely on physical strength.

Although it is impossible to recover quickly after physical exertion, there is a health that will [heal]. Ankang can't help his teammates recover their strength quickly, but he can use [Healing] to help his teammates recover their strength.

If An Kang and Song Qiushuang form a team for mixed doubles, it means that Song Qiushuang's flying bricks can be used indefinitely.

This is not only seen by Ankang, but also by the teenagers, and even by the fat man Anfu. Ankang pulled Ankang's sleeve and said, "Big brother, you and Qiushuang are really a perfect match!" A perfect match! ”
