Li Zhong only left for a few minutes before he successfully returned with Ling Yuzi. The Butterfly Ninja looked at Ling Yuzi who was in a mess and couldn't help but frowned: "Oh...is this what it is?"

Judging from the blood stains on Ling Yuzi's limbs and clothes, Ling Yuzi's limbs must have been cut off just now, and there are many blood stains on his body...but he has almost recovered now.

Ling Yuzi's eyes were filled with tears, and he refused to let go of Li Zhong's legs, like a frightened child...

The butterfly ninja was a little speechless, and he coaxed her for a few minutes before letting her go. The butterfly ninja took the spare parts to eat meat. The Demon Slayer kitchen was open for a long time because there were patrols and shift changes every night.

I also need to eat late night snacks and the like, so I don’t have to worry about running out of food.

In tonight's battle, Ling Yuzi also consumed a lot of energy. The energy required for healing after the limbs were cut off must be replenished with meat, otherwise Ling Yuzi may fall into a violent state...

Li Zhong looked at the leftover child that was taken away, and couldn't help but shrugged: "Oh... unlucky girl, this girl is really in trouble."

Yi Ti shook the sickle and couldn't help but frowned: "The remaining magic power is too little. I have to replenish some magic power in the next period of time."

This world can hardly replenish magic power from the air, and can only rely on the magic power transformation array. The magic power transformation magic circle actually does not provide much magic power, and it will take a lot of time to fill up the current total amount of magic power.

..

After saying that, Li Zhong yawned, walked towards the butterfly house, and said, "Then there is no other way, we can only wait for a while. Speaking of which, how much magic power can be stored in the sickle?"

"The main function of the sickle is not to store it. It can only use level 84 rune spells once at most." Yi Ti said.

"That's not bad. It's enough to use the 'One Arm of the Colossus' once." Li Zhong yawned and said a little sleepily.

Hearing this, Yi Ti was not very happy: "Don't you know anything else besides the 'One Arm of the Colossus'? I have obviously taught you so many offensive spells, but you can only use them in battle.

There are only a few, and the other rune spells were eaten by you?"

Li Zhong spread his hands with an innocent look on his face: "This is indeed my fault...but my mind was basically blank when I was fighting, so the rune spells I used were naturally the rune spells I had memorized.

And my total amount of rune spells is only that much, and among the eighty-fourth level rune spells, I only have the 'One Arm of the Colossus', so I can only use this as a metaphor."

"Tsk...that's true."

Yi Ti frowned, shook her head and said, "Forget it, you can also memorize other runes and spells."

"Yes, yes, I got it~" After Li Zhong finished speaking, he walked towards the laboratory. Just now, the Butterfly Ninja had sent Kibutsuji Mukai's heart to the laboratory, and Miss Tamashii and Yushirou were also exposed to this thing.

Miss Tamashi couldn't help but swallowed when she looked at the heart that was still active. She had been staring at this heart for several minutes, and her heart seemed to be beating along with Kibutsuji Mukai's heart.

, the frequencies of the two gradually began to synchronize...

Until the end of the day.

After Li Zhong opened the door, Miss Zhu Shi suddenly woke up, looked at Li Zhong, and couldn't help but smile: "Mr. Li Zhong, it's great that you are back safely..."

"It's not safe. We were ambushed."

Li Zhong said with a helpless expression: "The upper stringer is just a cover. Oniibutsuji Muzan arranged for the upper stringer to be used as a bait outside. After the swordsmen and pillars of the Demon Slayer Corps arrive, a ghost who can control space will release us all.

We’ve gone to their home stadium. Including Onimusuji Muzai, all the six Uegeki ghosts are here.”

Hearing this, Miss Zhushi's face suddenly changed. She realized something and asked cautiously: "Then... how many swordsmen are there who have returned?"

"Twenty ordinary swordsmen died in the infinite city of Tsuji Muzan, and the pillars are safe." Li finally found a chair and sat down, "If it weren't for the Blue Star Stone that can control space, this time

I’m afraid not many Zhu can come back alive.”

"Twenty swordsmen...you have twenty more blood debts on your hands." Miss Tamashi was holding the vessel containing Kibutsuji Mukai's heart, her hands were trembling slightly.

Seeing this, Li Zhong didn't let her think too much, and immediately asked: "Miss Zhuyo, don't think so much about other things. Kibutsuji Mukai's heart is here, and there should be some ghosts belonging to him in his heart."

Blood, is this ghost blood useful for research?"

"It's useful, of course it's useful. Rather, it's one of the best research materials!" Miss Zhuyo said excitedly, "As long as I have this, I'm confident that Miss Butterfly Ninja will develop a formula that will have an effect on him.

Very poisonous!"

Li Zhong couldn't help but laugh: "With your words, I feel relieved. Oniitsuji Muzan is not afraid of the Nichirin Sword. Even if his head and neck are damaged with the Nichirin Sword, he can still recover. I think

The only way to kill him is to use the sun. I believe that once the toxin is developed, Onimbutsuji will suffer a big loss."

Miss Zhu Shi nodded, then turned to look at Li Zhong and said, "Um...Mr. Li Zhong, I have something else I want to ask you for."

"What happened?"

"This is it." Miss Zhu Shi handed a test tube to Li Zhong. Li Zhong looked up and frowned slightly: "This is the blood I brought back last time. What happened?"

This is the blood that Li Zhong took from Nezuko yesterday. Ms. Tamashi has been studying it since yesterday...

Miss Zhushi said excitedly: "This is very powerful! I have never seen such ghost blood. It changes very quickly. As you said, this one is adapting to the sun... But it is a pity that this

The blood has lost its activity. After leaving the mother's body and being exposed to sunlight, the activity of this ghost blood has almost disappeared. I divided the ghost blood you gave me into two parts, and the other part is expected to be fully recovered in two days.

Loss of activity."

"But two days is not enough time for you to study it thoroughly, right?"

Li Zhong suddenly realized: "Understood, I will get it every few days. With this, and the blood of Kibutsuji Muzan's body, can the potion be developed within half a year?"

"This... is not necessarily true." Ms. Zhu Shi did not dare to make a 100% statement, "Because I don't know what else is needed to turn a ghost into a human. I can only study it slowly and try it. After the potion is developed,

, we still have to wait for clinical trials.”

"However, if it reaches clinical practice, based on the current progress, it will only take about half a year."
