Ruoqiang City, the city lord's mansion.

In a study room with simple decorations and displays, it is empty.

A table, a chair, a painting.

In the incense burner, green smoke curls and wafts in all directions. A green aura of grass and trees spread.

Inside and outside the smoke, a father and son, one in front and one behind.

"Death is death. Looking at his temperament, he knew that there would be such a day. ”

Looking at his father, who was motionless and steady as Mount Tai in front of him, his back was as wide as ever, and listening to the expected words, Wang Shaoyun only said one sentence: "I will trample him under my feet and step on him to a pulp."

Because, there was more hoarseness in my father's voice than it had ever been.

After packing up and making preparations, Du He and Du Teng went on the road again. The old man said, next stop, take him to pick up something.

As for the strict investigation, objectively speaking, Du He and Du Teng want to go, and the methods are simply not too much.

It's just that what the two didn't expect was that not long after they left the city, they were followed.

The snow-white beast that had disappeared for a long time was following the two of them not far away.

Du Teng beckoned to him when he found out, but instead he took a few steps back and hid. So, Du Teng no longer insisted, turned around and the two continued to hurry.

This walk is half a day. The little beast has been following behind without losing it. But Duten didn't care. It wasn't until they had lunch that the little beast came forward slowly.

Du Teng laughed. It turns out that this snack is waiting here.

After a beautiful feast, Du He took out the birch bird windboat. Thanks to it, it really saved a lot of time. Of course, the bluestone and source stone have also been used a lot. But Du He is not Du Teng, and no one knows how much he is really worth.

At the same time, Xiao Gang's scanning and analysis of the bird boat has also come to the final stage.

In these days, Du Teng borrowed a lot of various materials and related books and records in the name of the Datong Chamber of Commerce. Xiao Gang has already verified and recorded each other. With a considerable understanding of basic knowledge and material properties, Xiao Gang also carried out feasibility tests one by one, and came up with some gratifying derivative knowledge and theories.

Moreover, the ink ring that Jiang Mian gave to Du Teng at that time still contained a lot of finished products such as spirit weapons and trap beasts, which also provided him with better learning modeling objects. It can be said that the understanding of the world is a thousand miles a day.

During this time, Xiao Gang has been analyzing the data and structure of the bird boat, with the accumulation of knowledge in his previous life, and now it is finally time to harvest the results.

"The energy transmission system has been optimized"

"Hull fluid design completed"

"Verification of Energy Conversion Output Coefficient"

"The stability of the mechanical transmission and control system is normal"

......

"Hahaha, done!"

"Xiaogang, what are you yelling at?"

"I have successfully transformed the new version of the bird boat!"

"Yes. You're quietly doing big things. has a bit of a brother's demeanor. I love it!"

However, how could a scientific research straight rotten man take this kind of stalk, Xiao Gang just said excitedly: "The speed has increased three times." Stability and security improved by 30%. The drag coefficient is reduced by 41 percent, and the energy loss is reduced by 19 percent. How?"

"Excellent!" Du Teng's eyes lit up when he listened, and he couldn't wait to sit in it now. Because this bird boat is so much.

Compared with the three-domain vehicle, not only is the speed too slow, but it is also very ugly. Not to mention any attack power, protection, comfort and security, it can't be compared at all.

But now there is no way, and the next best thing is to settle for the next best, and Xiaogang's new design is already in a perfect state.

"Xiao Gang, hurry up, build one! Start now, immediately immediately!" Du Teng almost roared.

"One thing missing"

"Say, I'll get it for you."

"Wake up the alloy, which is liquid blue gold"

“？”

"Without this, the energy transmission system simply wouldn't work. This existing bird boat uses a complex active liquid that transmits energy in conjunction with the engraving of the back lines. However, this complex active liquid is made from a combination of a variety of animal and plant minerals, and I can't analyze the composition and ratio. And compared to it, the properties of liquid blue gold are obviously more suitable and better."

"With all that, you're planning for me to pull out the blue gold?"

"There is a second floor of the think tank"

"Phew! I want to too!" Du Teng had a headache and was depressed. The dream of soaring into the blue sky has been shattered.

It's still too weak. This life index is too difficult to do. I don't know when I will be able to reach twenty and open the second floor of the think tank.

My Liquid Blue Gold and Earth set. Brother wants to kill you.

After being soberly aware of his strength again, there was time left to hurry, and Du Teng was not idle. He was discussing something with Xiaobai. That is the problem of independent alchemy.

Indeed, with the old man's perfect demonstration, he can basically achieve it in one go. It's really beautiful. However, this is always a bit passive.

Can you do alchemy independently and freely?

After much research and discussion of assumptions and calculations, the conclusion is that it is perfectly possible.

Like all alchemists in this world, start from scratch, start step by step, fail and fail again, summarize and summarize, work hard and work hard. Perseverance and perseverance.

Well, Du Teng just thought about it for a while, and then he felt, forget it. Why is it so difficult to do something on your own?

If Du He knew about this idea, he was afraid that he would vomit three liters of blood. Oh, you're just thinking about it, we're really being abused a thousand times. We haven't said anything yet, what kind of emotion are you doing there.

In fact, if you really want to talk about it, Du Teng still has an advantage. Although he had to start from scratch and grope for a summary of the experiment little by little. But with the existence of Xiaobai, this process is bound to be greatly shortened.

And he doesn't care how many times he fails, he only needs to succeed even once, and it will be enough for him. With Xiaobai's record analysis and optimization, this Dan can be said to be finished for him.

There is no need to be like other alchemists, and you have to come countless times of successful experience to accumulate experience. Again, this is a huge advantage that cannot be matched.

After analyzing all the pros and cons and drawing conclusions, Du Teng had a number in his heart. As for whether to do it or not, and how to think about it, only he knows it in his own heart.

After discussing this matter, another question was raised.

That's the substitution of fire charms. Is there any other way to become a tinder instead of a fire talisman?

Otherwise, if you continue to do so, especially if you want to try to do alchemy independently one day, the consumption of the fire talisman will be too wasteful, and you can't afford to consume it at all.

So what to do?
