Yan Yan and Nu Yan leaned over, and the black owl also secretly came over to watch.

Nu Yuan, in particular, seemed a little unhappy.

Because not only has Lu Yu not come in to see them for a long time, but also because every time Lu Yu enters the small world, he will run directly into the arms of the female concubine.

For this matter, at the beginning, the female concubine didn't like it very much, after all, there was a person in the chest there, and it felt quite annoying.

But...... This is a matter of habit, just like raising a cat, at the beginning of the kitten rubbing on the body, naturally a little uncomfortable, but if it rubs for a long time, it becomes a habit, and it will like it very much.

Nu Yuan's mood now is like she has a cat, and then suddenly she doesn't kiss herself!

Of course, Lu Yu didn't care about this, and now all his mind was spent on this Dan furnace.

Dan furnace ...... Big!

It's really big, and it looks like a small hill.

It is possible to throw all the herbs into it at once and smelt them.

And the most important point is that the gadget made by Lu Yu is directly placed in the core of the Dan furnace, and then ......

After a little trial, Lu Yu thought that after passing the qualification, he would completely ignore it, he only needed to throw the white fire into the core, let it connect with that core, and the entire Dan furnace would run on its own!

"Oh, if I had thought of using this method earlier, it would have saved a lot of energy, and really, why didn't I think of it until now?"

Looking at the Dan furnace in front of him.

Lu Yu didn't think there was anything about it, it was just an integration of his own strength.

But in fact, Lu Yu didn't expect or realize that this matter was ...... It's really too big!

This is the first time in all the worlds that two completely different ideas, including three different energies, have been put together in one thing.

Maybe...... Nothing like creating life is as important as this technological breakthrough!

To put it simply, when the information development of the previous world goes through a certain process, there will always be a huge technological explosion when it is integrated.

When the steam principle and lever gear machinery are combined...... The steam engine appeared.

Linked to the chemical industry, the replacement of boilers with oil and gas has become an internal combustion engine, making another leap forward in science and technology.

When electricity is added to it...... The whole thing is buried to an unimaginable extent, and the car that everyone knows is created.

When the electronic chip is added again...... Simple control, electronic assistance, unmanned driving, and even ...... Levitation technology!

Fusion, then development, this is a kind of progress and leap forward that all the world has to face.

What Lu Yu did at this time was to completely unite the things of several different worlds, the things of the origin.

In the earliest days, in fact, Lu Yu also unconsciously tried, such as combining the tank machinery of the previous life with the spirit stone energy of another world, and he made the kind of power that changed the entire world. When he combined the banking system of his previous life with the business culture of another world, it was like a chemical reaction, and he became a behemoth like the Hua Family Chamber of Commerce.

And now, he's not just a superficial fusion, but a combination of energy and energy, technology and technology, ideas and ideas, and then ...... And then all combined!

If it is placed in the world of the previous life, I am afraid that people can't help but evaluate it like this.

When metaphysics and science come together in a peaceful and perfect way, it is destined to change everything.

But now, Lu Yu can't think of so much.

All he wanted was to refine all the pills as quickly and conveniently as possible.

No, to be exact, it's really not an elixir.

And Lu Yu didn't lie to anyone, this is really used for bathing.

When Lu Yu was worried, when he couldn't take his eyes off it......

Lu Yu found a ...... It's a wonderful thing, even if he doesn't have to refine this thing by himself, his eyes just can't leave it, just watch it come automatically.

So what's the point of this automatic?

Lu Yu hurriedly shook his head and pulled his thoughts out of refining the pill.

Looking at the three women beside him, it was only then that he remembered to care.

He asked, "That...... Black owl, how has it been inherited recently?"

The black owl hurriedly said: "Very good, very good, although I have encountered a little bottleneck, I feel that it should be able to pass on the good things soon." ”

Lu Yu frowned and said, "Soon, it's been more than two years......

The black owl said with a bitter face: "If it hadn't been spent so much effort to repair it, it wouldn't be like this now, right?"

"Hmph. ”

Lu Yu rolled his eyes and glared at her, but it wasn't blame.

Then he looked at the female concubine and found that her upper body had been filled with more than half of it, and it was almost to her lower abdomen, and the beauty of her whole body still made Lu Yu's heart flutter.

Coughing embarrassedly twice, Lu Yu floated over directly, and then lay up......

Well, it's still the best location.

Then he said to Yan Yan: "What, when I came in, I found that this small world didn't seem to have changed much, nor did it expand, nor did it become heavier......

Yan Yan rolled his eyes and said, "Besides, it's been more than two years, have you cultivated and grown?"

"I ......"

Lu Yu scratched his head in embarrassment.

Yan Yan said again: "I thought that you got a lot of energy in that war, how could you give us some of it, at least to make this small world more beautiful, but it's better for you to imprison all the energy in your body, even if I deliberately suck it...... Ahem, it's nothing, anyway, you're wasting that power, do you know? It's better to put it in a small world, after all, the small world is your world, it's the source of your energy, right?"

Lu Yu wiped the cold sweat that didn't exist on her forehead, Yan Yan, this girl said that she leaked her mouth, she really had plans to steal energy from herself? This little girl...... It's getting too much!

See the chapter of the h, section 7 "N on y%g."

But in fact, if you think about it carefully, Yan Yan's statement is not wrong.

So much energy, yes, in that war, Lu Yu got more energy than all the energy he had ever gotten at all times combined!

Especially this is the life force, which can completely raise the current small world to a level.

The reason why they are still trapped in their bodies is for two reasons.

The first is because Lu Yu is afraid, afraid of encountering something special, such as suddenly being trapped in that space-time crack, or something, anyway, it is something that makes his thousand-year-old life directly consumed, if he encounters it, he can still use those energies to extend his lifespan, which can be regarded as a means of saving his life.

The other is because Lu Yu is worried that after the small world becomes too powerful, his body will not be able to keep up.

Originally, Lu Yu's realm was far higher than the strength of his body and the strength of his energy, if the small world was incredibly strong, what would Lu Yu do? Will he be broken by the small world? and then directly ...... Hung up?

Although the probability is very low, it does not mean that there is none.

This is something that Lu Yu is a little afraid to try.

Therefore, he had been counting on his cultivation to be enriched and developed in this world before he would consider anything else.
