Qin Lu was also very pleasantly surprised when such an ability suddenly appeared in his brain.

However, this is not unexpected.

The fusion of the souls of the two worlds is not just as simple as developing the brain.

In his previous life, he had traversed so many secret realms, and he naturally knew that the soul was a magical place, and the soul of a ninth-level martial artist was definitely much stronger than the soul of an ordinary person, and the reason why a high-level martial artist was able to see through the strength of a low-level martial artist was because the soul was stronger than it and could see through the energy fluctuations on their bodies.

Exclude, of course, those who are gifted and have adventures.

Now, the situation in front of Qin Lu is the same as when he was a ninth-level martial artist and looked at a low-level martial artist.

"Level 1, peak, but there is still some distance from level 2!" Qin Lu breathed a sigh of relief, but his vigilance did not let go.

First-level martial artists, with the blessing of their weak true qi, can have a maximum strength of three hundred catties, and if they match, the speed can enter one hundred meters and ten seconds.

However, their little bit of true qi, when they really fought, if the exercises were rubbish, they wouldn't be able to hold out for even ten minutes.

But Qin Lu is different, Qin Lu has a physical strength, as long as he is not tired, he can keep it all the time, not to mention the long, two or three hours is no problem.

Although the strength and speed are not as good as Sun Xu in front of him, Qin Lu is confident that with the martial arts that he has practiced in his soul in his previous life, playing with Sun Xu is like playing.

Sun Xu and Qin Xue were silent for a moment, Sun Xu suddenly looked at Qin Lu, and looking at it, he suddenly said:

"Huh? Are you, Xiaoxue's younger brother? ”

When Qin Xue heard this, she immediately frowned, and shouted, "Sun Xu, are you investigating the old lady?" ”

"I'm sorry Xiaoxue, I ......" It can be seen that this Sun Xu still likes Qin Xue very much, and he is still more principled, of course, it may also be the restriction of national power on their warriors.

However, he didn't rely on his own strength to bow hard to Qin Xue Overlord, and he can be regarded as a poor and cute guy.

"Mr. Sun, although it is said that there is no right or wrong in the pursuit of girls, but we must also pay attention to whether you are willing to do it, is it a little unreasonable for you to stop us like this......" Qin Lu walked out from behind Qin Xue, stood in front of Qin Xue, and said in an indifferent tone.

Qin Lu suddenly showed a temperament that far exceeded that of his peers, making even Sun Xu, who had lived in another circle since he was a child, a little stunned.

In fact, having said that, the circle that Qin Lu existed in his previous life was much more advanced than the environment in which he lived from childhood to adulthood now.

After all, a world full of martial artists and demon beasts is much more advanced than their circle of petty martial artists.

"I'm sorry Xiaoxue, it's my fault to disturb you, but I'll keep going!" After Sun Xu finished speaking, he turned around and left!

Very crisp!

"Huh? Why did he just leave so simply! Qin Xue looked at the direction of Sun Xu's departure and said suspiciously.

"Hmm...... Maybe the conscience has found out! Qin Lu smiled slightly, and only he and Sun Xu knew what was going on.

Sun Xu, who walked around the corner of the experimental building, leaned against the wall, patted his chest, and gasped twice.

"His momentum just now is so terrifying, at least he has the strength of dark energy!" Although Qin Lu's strength is not so high, his soul power is far beyond him, and the momentum that leaks makes him directly scared away.

As for what I just said, I will insist, purely for the sake of face.

Poking his head out and taking a look, Sun Xu hurriedly ran away.

……

On Qin Lu's side, the two of them sent Sun Xu away, and they went directly into the laboratory.

When she came to her home field, Qin Xue was handy.

Coming to the material room, Qin Lu found the raw materials he needed, and then went to the laboratory, began to heat and melt, and made the required materials according to the ratio he thought of.

When he came to the laboratory, Qin Xue was responsible for controlling the instrument, and Qin Lu was responsible for feeding.

The more Qin Xue looked at it, the more she felt that Qin Lu had a drama in this matter, and she was also excited, and fell into scholar mode, and the two of them worked together, and soon, the original version of the first battery was made.

I took it to a professional test instrument and tested it, and this battery is about the size of an ordinary Apple mobile phone battery, with a capacity of 8736 mAh.

"Oh my God, Qin Lu, what did you come up with, such a small battery, it has such a high capacity!" Qin Xue looked at the battery in Qin Lu's hand and said in surprise.

This battery capacity tester is also what they usually use for experiments, although it is not as precise as the energy side, but it is also a genuine thing, and the error will not exceed ten milliampere.

The thing Qin Lu made was the size of an ordinary Apple mobile phone battery, but it had a capacity of more than 8,000 mAh.

"No, this is still a bit flawed, according to my design, such a small battery, the theoretical capacity can reach 100,000 mAh, which is too bad!" Qin Lu frowned, thinking about what was wrong in his mind, and muttered.

"One hundred thousand, Qin Lu, are you crazy, just more than eight thousand, as long as you sell the technology to mobile phone manufacturers, you will make a fortune, no, no, no, if you publish this principle, maybe you can win the Science and Technology Progress Award!" Qin Xue said excitedly.

"Superficial!" Qin Lu glanced at Qin Xue, rolled his eyes, took the battery off the test instrument, and threw it into his pocket.

"Sister, have you written down all the data I added just now?" Although Qin Lu himself wrote down the amount of ingredients he had just added, he still asked Qin Xue.

I've got to find something to do for my sister!

"Written down!" Qin Xue nodded, her excitement still hadn't fallen.

"Remember, don't tell anyone about this thing, this is the foundation of our family's survival in the future, and you will have a dowry in it in the future!" Qin Lu told Qin Xue, for fear that this scientific madman would publish his research results.

"Don't worry, I know how important things are!" Qin Xue nodded, although scientific research was very important, but when it came to the vital interests of her family, she still focused more on Qin Lu.

"That's good, let's continue, this time, I'm going to adjust the feeding ratio!" Qin Lu nodded, then walked to the test bench, turned on the instrument, and made materials for the second battery.

"15478 mAh!"

"23,693 mAh!"

"47,865 mAh!"

"68,999 mAh!"

"98,754 mAh!"

Five more batteries were made in a row, and the final capacity was stopped at more than 98,000 mAh.

"Oh my God, Qin Lu, you won't really be possessed by aliens, or will you get the system or something?" Qin Xue didn't stop with a surprised expression all the way.

Seeing Qin Lu stop the capacitance of the battery at more than 90,000 milliamperes, he was almost stupid.

"Well, barely qualified!" Qin Lu nodded, although this thing can be improved further, but if it progresses further, the price will be great, and it will be cost-effective to sell it if it is made for personal items or mobile phones and computers customized for those rich people in the future.

As for the failed products just now, they are not considered failures.

In doing business, we all pay attention to releasing technology step by step.

Even if it is an 8,000 mAh mobile phone battery, put into this world, it is a scorpion's poop - the only one.

"Sister!" Qin Lu put the last battery in his pocket, looked at the experimental data recorded by Qin Xue, breathed a sigh of relief, and called out.

"What's wrong?" Qin Xue looked up at her younger brother, who seemed to have changed into a different person, and tilted her head and asked.

"I made it!" Qin Lu spread his hands, tilted his head slightly to the right, and said with a smile.

"I've finally taken the first step to protect you......"

Looking at Qin Xue with a sluggish face, Qin Lu was also relieved in his heart!
