Qin Lu was also very surprised that such a ability suddenly appeared in his brain.

However, it is not surprising.

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

After exploring so many secret realms in the previous life, I naturally know that the magical place of souls is. The soul of a level nine warrior is definitely much stronger than that of an ordinary person. The reason why high-level warriors can see through the strength of low-level warriors is because their souls are stronger than their energy fluctuations.

Of course, exclude those talented and adventure-loving guys.

Now, the situation in front of Qin Lu is the same as when he was a level nine warrior, he looked at a low-level warrior.

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

First-level warriors, with the support of their weak true energy, can have up to 300 kilograms of power. If matched, their speed can reach 100 meters and ten seconds.

However, if their weak true energy really fights, if it is garbage in the martial arts, they will not be able to hold on 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. Not to mention his longevity, it will be fine for two or three hours.

Although his strength and speed are not as good as Sun Xu in front of him, Qin Lu is confident that he can play Sun Xu as much as he can with his martial arts in his soul in his previous life.

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

"Hmm? You are Xiaoxue's younger brother?"

When Qin Xue heard this, she frowned and shouted sternly: "Sun Xu, are you investigating me?"

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

However, he did not rely on his strength to attack Qin Xue's domineering king, and he was a pitiful and cute guy.

"Mr. Sun, although there is no right or wrong in pursuing girls, we must also pay attention to your love and I am not willing to do so. Is it a bit unreasonable to stop us like this..." Qin Lu walked out from behind Qin Xue, stood in front of Qin Xue, and said in a calm tone.

Qin Lu suddenly showed a temperament that was far beyond his peers, which made Sun Xu, who had lived in another circle since childhood, feel a little stunned.

In fact, after all, Qin Lu's circle in his previous life was much more advanced than his current living environment since he was a child.

After all, a world full of warriors and monsters is much more advanced than a circle of warriors like these small-scale warriors.

"I'm sorry Xiaoxue, it's my fault to bother you, but I will still stick to it!" After Sun Xu said that, he turned around and left!

Very straightforward!

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

"Well... maybe it's because of the discovery of conscience!" Qin Lu smiled slightly, only he and Sun Xu knew what was going on.

Sun Xu, who walked past the corner of the experimental building, leaned against the wall, patted his chest, and took a breath.

"His aura just now was so terrifying, at least he had the strength of dark energy!" Although Qin Lu's strength was not that high, his soul power was far superior to him. The momentum he exposed scared him away directly.

As for what I just said, I will persist, it is purely for the sake of face.

He poked his head out and took a look, and Sun Xu quickly ran away.

...

On Qin Lu's side, the two of them sent Sun Xu and went straight to the laboratory.

Qin Xue was very good at coming to her home court.

When he came to the material room, Qin Lu found the raw materials he needed, then went to the laboratory, started heating and melting, and made the required materials according to the ratio he thought of.

When he arrived at the laboratory, Qin Xue was responsible for controlling the instruments and Qin Lu was responsible for adding the materials.

The more Qin Xue watched, the more she felt that Qin Lu had a chance, and she became excited and fell into the scholar mode. The two of them worked together, and soon, the original version of the first battery was made.

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

"Oh my god, Qin Lu, what did you make? Such a small battery 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 used when they usually use it for experiments. Although it does not have the precision of energy, it is also an authentic thing, with an error of no more than ten milliamperes.

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

"No, there are still some flaws. According to my design, such a small battery can reach 100,000 milliampere hours, which is too bad!" Qin Lu frowned, thinking about what was wrong in his mind, and murmured.

"100,000, Qin Lu, are you crazy? Only more than 8,000, as long as you sell your technology to mobile phone manufacturers, you will be rich. No, no, if you publish this principle, you may be able to 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 recorded all the data I added just now?" Although Qin Lu wrote down all the materials he added just now, he still asked Qin Xue.

You have to find something for your sister!

"I've remembered it!" Qin Xue nodded, and her excitement still did not fall.

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

"Don't worry, I know the importance of big things!" Qin Xue nodded. Although scientific research is important, she still focuses more on Qin Lu when it comes to her own personal interests.

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

“15478 mAh!”

“23693 mAh!”

“47865 mAh!”

“68999 mAh!”

“98754 mAh!”

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

"Oh my God, Qin Lu, you won't be really possessed by aliens, right? Or have you gotten the system or something?" Qin Xue didn't stop looking surprised all the way.

Seeing Qin Lu stop the battery capacitor at more than 90,000 milliamperes, he almost became silly.

"Well, I'm barely qualified!" Qin Lu nodded. Although this thing can be improved further, if it improves further, the cost will be high. In the future, it will be cost-effective to sell it if it is made into personal items or mobile phones customized for wealthy people.

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

When doing business, you always focus on releasing technology step by step.

Even if the 8,000 mAh cell phone battery is placed in this world, it is the Scorpion's father - the only one.

"Sister!" Qin Lu put the last battery into 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 looked like a different person, and asked with her head tilted.

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

"I finally took the first step to protect you..."
