Mu Yunxiao didn't even think about what was going on. When he heard Bai Chi say it hurt, he panicked.

"What's wrong? Are you feeling uncomfortable because you've consumed too much mental energy?"

He didn't know what Bai Chi had done. He only knew that he was on the third floor, but he used his mental power to strangle the zombies on the top floor.

But in terms of distance, none of the psychics he knew could do this.

Even few people can strangle zombies with their mental power. Their greatest ability is to block the zombies' perception or disperse them.

Bai Chi lay on Mu Yunxiao's chest, pulled Mu Yunxiao's hand, placed it on her temple, and rubbed it twice like a kitten.

"I have a headache. Please give me a massage."

As expected of a fire-type mutant, he is still wearing a thin shirt even though it is already autumn.

A hot breath came from Mu Yunxiao, and it seemed to penetrate directly into his limbs and bones through the contact of the skin, dispelling some of the coldness that was like a thorn in the bone.

He was imprisoned underground without seeing the sun for many years. The only warmth he felt in his lifetime was from the little child who accidentally broke in.

Mu Yunxiao sat on the edge of the bed and helped Bai Chi change to a more comfortable position. He still let him lean in his arms, and his big hands gently massaged Bai Chi's temples.

"Have you overdrawn your mental strength? I still have a few crystal cores stored here. Would you like to absorb some?"

As he spoke, Mu Yunxiao took out a few crystal cores. They were fiery red in color, and just looking at them made one feel warm.

The energy contained in it is also stronger and more sufficient.

Bai Chi held the crystal cores in his hands. There were four of them, but they were more energetic than the tens of thousands of crystal cores he had just collected.

"Is this something you keep just in case?"

These are all high-level crystal cores, one level five, two level fours, and one level three.

This should be Mu Yunxiao’s entire fortune.

"I guess so. Sometimes when we encounter high-level zombies, our energy is consumed too quickly and we don't have time to replenish it. Using crystal cores will be faster."

People with special abilities can practice on their own, but the rate of improvement will be very slow.

Bai Chi played with the crystal core in his hand, but did not absorb it.

The dry big hands kept pressing on him tirelessly. The brain was the center connecting to that huge mental power.

Following Mu Yunxiao's actions, his somewhat violent mental energy slowly calmed down.

Bai Chi half closed his eyes, still the same as many years ago.

"Achi?"

After not receiving a response for a long time, Mu Yunxiao couldn't help but feel anxious.

Bai Chi came back to his senses and chuckled: "Yes, crystal cores. I need a lot of crystal cores, the more the better."

Mu Yunxiao said hurriedly: "Then absorb these first, I will find them for you later."

But Bai Chi shook his head and refused.

"It's too little. Besides, I'm not using it right now. The power of the crystal core can strengthen my body and can barely organize my mental strength, but..."

"But it's better than nothing. What I've consumed, what the crystal core can hold to strengthen my physique, and what I've absorbed by organizing my mental power are far less than the speed at which my mental power is growing."

Bai Chi said it lightly, and Mu Yunxiao actually thought about it for a few seconds before he finally understood what Bai Chi meant.

"Achi, are you saying that you're not overdrawing your mental strength, but that your mental strength is too great, so you feel uncomfortable? That's why you're so weak?"

Bai Chi nodded gloomily: "Yeah, that's what I mean."

This is simply a vicious cycle.

The faster the consumption, the faster the growth.

He just tried it on a whim, but the sudden increase in his mental strength forced him to take the risk of being exposed and take Mu Yunxiao over.

"Hmm~" With a muffled groan, Mu Yunxiao quickly came back to his senses and lowered his head to kiss Bai Chi's eyebrows.

"Sorry, did I hurt you?"

I was distracted just now, and the strength in my hands couldn't help but increase.

Bai Chi slowly shook his head: "It's okay."

Mu Yunxiao observed his expression carefully and confirmed that his face looked more relaxed than before.

After thinking for a moment, he carefully asked, "Achi, will you feel more comfortable if I help you press it like this?"

Bai Chi lazily raised his eyelids, wanting to say no, but ended up seeing Mu Yunxiao's eyes full of heartache.

After a pause, he pursed his lips and sneered, "Not everyone can help me sort out my spiritual power."

Mu Yunxiao was stunned for a moment, then realized what was happening and asked in surprise, "So, it's just me?"

Bai Chi hummed, then added, "Before you, no one who tried to touch my spirit body survived."

His spirit body seemed to have its own consciousness and would react quickly before he could react.

But they are indeed one and the same. Perhaps, the mental power just knows his thoughts faster than he does.

I thought Mu Yunxiao would be scared if I said this.

However, the result was that Mu Yunxiao suddenly lowered his head and kissed Bai Chi hard on the lips.

"Baby, I knew I was the only one who was different!"

Bai Chi blinked. Is this guy suddenly a little too excited?
