Hallek shook his head, put the empty test tube in his hand, and used his mental power to probe the large text information in his crystal ball, and said indifferently: "If the creatures in nature are infected with the Abyss Mayfly, and there is no cure, a month of weakness for those creatures is simply a certain death.

But in the wizard's lab, you just have to wait quietly, no one will threaten your life, just have a serious illness. ”

"Hmm."

After Yang Hao answered casually, he slowly closed the book, and fell asleep on the bed in the corner of the laboratory with extreme fatigue.

Hallek glanced at Yang Hao, seemed to recall himself back then, and after sighing, he quietly left the laboratory later.

…

Half a month later.

Yang Hao, who was lying on the bed in an almost dying state, was so thin that his body was like skin and bones, his eyes were dizzy, and he wanted to sit up and continue the experiment before resting, but he didn't have the strength to do so.

Hallek frowned and said, "Seventeen days to reach the high-speed breeding period, is it because of the oral abyssal mayfly?" In this case, it will be twice as fast as expected. ”

After speaking, Hallek's thin fingers opened Yang Hao's eyes, and after a simple light witch, it was confirmed that Yang Hao's pupils still had a slow reaction.

"Because the time is too short, the life energy absorbed by the body can't keep up with the energy demand of the abyssal mayfly multiplication?" After pacing around the room a few times, Hallek suddenly whispered out of the room, "Two dogs." ”

The black cat ran over vigorously, cocking a black tail, and wondered, "Old man, what's wrong?" ”

"Leave a little bit of your smell on him." Hallek pointed to Yang Hao, who looked like he was dying on the bed.

"Leave a smell?" The black cat looked at Yang Hao's declining appearance and said in a low voice: "Really, if you have to be so messy, you actually take that thing orally, now you have to rely on me to save you." Saying this, the black cat jumped on Yang Hao's body, and after a while, when he raised his hind legs, a small column of water fell on Yang Hao's face.

After urinating, the black cat jumped off the ground and said, "It's done." ”

"Hmm." After Harek agreed, he "picked up" Yang Hao from the sickbed and took him to the innermost laboratory.

In the most heavily guarded and mysterious core laboratory, there was only a black box the size of a coffin.

Hallek lifts the lid of the "black coffin", and the space in it is strange and extraordinary, and the scale is stretched to the limit.

From above, you can see a chessboard-sized continent and ocean, as well as celestial phenomena such as clouds shifting.

This is... World Laboratory.

"Let me see, where is the cultivation pool? Kindness... Got it. ”

Hallek found his position and threw Yang Hao down, landing right in the middle of an endless giant lake.

The arrival of uninvited guests alarmed many creatures in the lake, including huge predatory fish.

However, because of the black cat's urine, those ferocious-looking carnivorous fish fled desperately at the moment Yang Hao entered the water, swimming to nowhere.

…

Three days later.

When Yang Hao opened his eyes, he saw that he was lying in the water, and he immediately struggled instinctively, but his excessively weak body made Yang Hao's so-called struggle look so weak.

"Knock, knock, knock."

Yang Hao heard the sound, and after controlling himself to calm down, he tried to look up, just in time to see the huge head of the black cat in the sky.

The black cat said word by word: "One more day of cultivation, your master and master will prepare restorative food for you." The voice was a little blurry through the water, but Yang Hao barely understood, and blinked twice to show that he knew.

At this time, Yang Hao was lying in the lake, a little curious about his ability to breathe underwater, and surprised by the silence around him; As he began to sense the situation of his body again, the water in this large lake seemed to have some strange function, and it was able to produce a rare energy that nourished the body.

At this time, although Yang Hao's body was still weak, the abyssal mayflies in his body seemed to have reached the limit that Yang Hao's body could bear because of the number, and they were no longer reproducing, forming a symbiosis period with Yang Hao.

Somewhat tired, Yang Hao closed his eyes again.

…

Twelve days later, after crystal ball monitoring, Yang Hao's body has completely recovered, and his physique has reached 7.3 points. It was supposed to be 7.8 points, and there were 0.5 points of constitution that were permanently lost due to excessive consumption of cellular energy in a short period of time.

It is worth mentioning that the first thing Yang Hao did after he was able to act independently was to prepare a bottle of deodorization potion, which eliminated the smell left by the second dog (black cat) on his body, and once again maintained a completely odorless physique.

Hallek nodded on the side and said, "The recovery is good, in this case, you can now carry out the formal cultivation of the Abyss Refining Body."

Well, but because of your low constitution now, you can only use some irritating poisons that are not lethal. In this case, if it is an ordinary wizard apprentice who cultivates the Abyss Refining, he will inevitably take or inject some weak poison under the guidance of the teacher, but in my case, there is a better choice. ”

Saying this, Harek actually took Yang Hao to a room that was completely enclosed by witchcraft prohibition, and then took out a fully enclosed metal vessel from inside.

"Inside is a precious radiant stone of weak radiation. However, although it is of low intensity, if exposed to the civilian world, people within a radius of 50 meters will weaken and die in a day, and within a radius of 1,000 meters, there will be varying degrees of poisoning, which is a hazardous substance that requires strict monitoring. ”

Saying this, Hallek said to Yang Hao again: "However, this poison is the most suitable for your auxiliary cultivation in the early stage. First, there will be no irreversible lethality, and secondly, it can be reused, and you only need to control the time of poisoning during the period before and after.

In addition, I also stuffed the star color you brought back, so there will be some life force extraction effect, which will stimulate you to improve the witchcraft of the nature of curses, weakness, etc. ”

After Yang Hao was pleasantly surprised for a moment, he took the closed vessel and asked, "Then after each cultivation with the radiant stone, how much physique can I grow approximately?" ”

"A little bit or so." Hallek affirmed: "After each cultivation, the body recovers for 10 days, then you use this radiant stone for three months." You will be able to cultivate your physique to 15 or more.

Wait until half a year later, because your physique has increased, and the Abyss Mayfly Barrier has been passively poisoned for a long time due to the toxicity of radiant stones, and has developed a resistance to passive evolution, so it will be difficult to rely on radiant stone cultivation to play a role anymore, and then I will guide you in the real poison concoction. ”

Passive evolution?

Yang Hao noticed a key word used by Harek's mentor.
