The two individuals from before had each produced several kilograms of blood for the experiment, their bodies' hematopoietic capabilities struggling to keep up.
"Mmm..."
It had been years since Lin Xiao had last felt such profound weakness. If not for his innate true qi providing support, he would have collapsed.
The冥医 (Míng Yī - Nether Doctor) had reached his limit later, with the blood for the final few experimental runs being his.
The day and night of experimentation had finally yielded results.
He sat down cross-legged and began circulating his true qi, his innate qi forming a protective barrier. The spiritual energy in the air slowly entered his body, helping him to accelerate blood production.
After completing one cycle, he felt much better and finally picked up his phone to call Ye Chen.
Ye Chen, who had been waiting outside listlessly, saw the phone ring and immediately answered, "Brother Xiao, are you done?"
"Mmm... anything else going on outside?"
Lin Xiao asked, as he reviewed the surveillance footage. The recordings before the cameras were destroyed were still available.
He had seen the enormous body and the massive explosion.
"No one else has come to seek death out of boredom," Ye Chen said. "Brother Xiao, there's something. I want to come in and talk to you. I discovered something."
"Come in."
Lin Xiao immediately opened the door to the underground passage. Since Ye Chen had said so, it was clear he had stumbled upon some unusual secret.
Ye Chen quickly arrived at the room where they were, and upon entering, saw Lin Xiao sitting cross-legged and the 冥医 (Míng Yī - Nether Doctor) with a pale, paper-like complexion.
"Brother Xiao? 冥医 (Míng Yī - Nether Doctor)? What's wrong with you two?"
Ye Chen's expression changed, and he hurried over to support the 冥医 (Míng Yī - Nether Doctor).
Ning Fengzhi also rushed over with two large boxes of milk, placing one in front of each of them. He said, "The two of them have lost too much blood and need nourishment... You take care of them, I'll go boil some eggs."
With that, Ning Fengzhi bustled away.
"Okay."
Ye Chen said, and quickly opened one box of milk for the 冥医 (Míng Yī - Nether Doctor), who appeared to be in worse condition.
It was at this moment that he suddenly felt a violent surge of spiritual energy.
The crystal, still in its pocket, was against the 冥医 (Míng Yī - Nether Doctor)'s back.
"Hmm?"
Almost simultaneously, Lin Xiao also noticed something was wrong.
The spiritual energy in this underground laboratory was already sparse. From just a moment ago, he could barely feel it. Then he realized all the spiritual energy was now being drawn away by Ye Chen.
More accurately, by the object in Ye Chen's pocket.
"What is it?"
Lin Xiao looked at Ye Chen.
Ye Chen then took the crystal out.
"This."
At this point, Ye Chen noticed that the spiritual energy within the crystal seemed to have diminished significantly.
And the 冥医 (Míng Yī - Nether Doctor), who had just finished drinking the milk, had a ruddy complexion.
"Is it this thing?"
Ye Chen's eyes lit up.
"Let me see."
Lin Xiao extended his hand and took the object from Ye Chen.
"Brother Xiao, this is what was left after those artificial humans outside combined and exploded. I don't know what it is, but it survived the explosion intact, so it might be something good. I kept it. I just brought it for you to see if you know what it is."
Ye Chen quickly explained the origin of the crystal.
"Pure, without any impurities."
Lin Xiao examined it in his hand. The next moment, he felt a warm current flow into his body through his hand.
