After the crystal entered his head, Su Tianyu did not notice discomfort.

It just seemed to be a little numb, and soon, more and more crystals entered his head, and Su Tiankun was in pain.

The sweat on his forehead was getting bigger and bigger, and his brain felt like it was going to explode.

Something was gnawing at his head, trying to carve out a world here.

Qin Lanzhou stared at the instrument, which was made by Su Jiao before, and he could see the situation of the brain.

Fortunately, he had studied medicine before and was very familiar with them, so he could observe whether Su Tiankun was in danger at any time.

"Second brother, if you can't stand it, just tell me directly, and I'll stop." Su Jiao didn't choose to put the crystal in when Su Tiankun was sleeping, she was worried that if she was asleep, she would really fall asleep all the time.

"Good. I can still bear it, Jiaojiao rest assured. Su Tiankun's voice was already a little weak, but he still wanted to persevere, until he couldn't bear it anymore, he wanted to see if he could create this miracle.

The movements in Su Jiao's hands did not stop, and she put five crystals of Libei beads into Su Tiankun's brain in a row.

Time flies slowly.

It wasn't until the seventh one was all introduced that five hours had passed since they entered, and then, Su Jiao heard Qin Lanzhou's voice: "Jiaojiao, stop." ”

His words made Su Jiao sweat instantly: "What's wrong, too much?" ”

Qin Lanzhou hurriedly said, "No, it's the second brother's brain domain that has changed, you see." ”

Following Qin Lanzhou's hand, Su Jiao saw Su Tiankun's head, at this moment, Su Tiankun's head scanned the screen, and his head was no different from that of the alliance humans.

"So, here we are, succeeded?" Su Jiao had a rare excited expression.

She put the two Libei beads in Su Tiankun's hand, and absorbed the rest.

Qin Lanzhou untied Su Tiankun and gave him a glass of water: "Second brother, take a rest." ”

"Hmm."

Su Jiao squatted in front of Su Tiankun: "Second brother, where do you feel uncomfortable?" ”

Just now, the brain was like exploding, there was a force in his brain rampage, he thought he was about to explode, but in an instant, he noticed the change.

After Su Jiao completed the introduction of the seventh Libei Pearl, he noticed something different.

That is, the head at this moment is very empty, as if it can accommodate the mountains, rivers and seas.

"I don't feel uncomfortable, it's just that I find that my brain is very empty now, as if there is a big open space in it, and I urgently need to plant something to go down."

"Then you absorb these two Libei beads, this should be the consumption of expanding the brain domain just now, and after the brain domain is widened, it will indeed be like this, you can take a break and absorb the crystals of the two Libei beads."

Holding it in his hand, Su Tiankun didn't see how to use it when he looked left and right.

Qin Lanzhou gave him a demonstration, pinching the Libei beads with his fingers, crushing them, the crystals were scattered around, and after one breath, these crystals disappeared.

"Release your spiritual power, as long as you touch these crystals, they will follow the spiritual power you released and return to your brain."

Su Tiankun tried, but he didn't know the point, so Su Jiao taught him how to use mental power, and when the two of them taught Su Tiankun proficiently, another three hours passed.

The experiment took almost eight hours.

The instrument recorded the whole process, as well as all the data, with this data as a reference, the next time the mental power is stimulated, the two of them will have reference data.
