After discussing the matter of joining the research with Kushina, and then handed over the technique of the weight-bearing seal to Kushina, the night god was ready to participate in the research after a while.

Why not go right away?

Because I still owe almost 2,000 sets of weight-bearing equipment that I haven't completed.

Night God calculated in an instant, if he started with all his strength, plus the three of Kakashi and Turin to help, he could still complete it in ten days and half a month.

After all, only the materials and the completion of the seal need to be done by yourself, and it doesn't matter if you do the rest yourself.

The three of Kakashi had received the weight-bearing equipment teleported by the night god before, but they were actually quite embarrassed in their hearts. Because the price of the load-bearing equipment is particularly expensive, and the three of them don't know, in fact, the cost of the night god is very low.

So when the night god instantly called them to help, the three of them agreed without hesitation.

In short, with the help of three people, half a month later, Yeshen finally completed all the orders. After making some more weight-bearing equipment as a backup, Night God immediately went to Konoha Hospital, preparing to officially join the Yin Seal research.

I don't know if Tsunade and Kushina will beat themselves to death after releasing their pigeons for half a month.

With apprehension, the night god instantly pushed open the door to the research room.

With a "ding" sound, the moment the night god walked in, a kunai flew between his legs and nailed to the wall of the corridor behind him.

"Yo, it's an instant, I thought it was." The night god instantly saw Kushina walking towards him step by step with a kind smile on his face.

"Sister Jiu Xinnai, if you have something to say, you put down the knife first!" Night God took a step back, feeling his hairs stand on end.

"Don't be afraid, boy, haven't I just reported for half a month, am I the kind of person who will be angry with you?" Kushina's smile remained unchanged and continued to get closer step by step.

“…… I was wrong, please let it go. Looking at the firewood knife in Kushina's hand, ah no, the scalpel, the night god instantly said that he would not hesitate when he should coax.

"Cut, stinky boy, I finally know it's coming." Looking at the appearance of the night god instant, Jiu Sinai didn't bother to tease him anymore, after all, the weight-bearing equipment made by the night god instant also played an important role in Konoha , and of course Jiu Sinai wouldn't really be angry because of this.

Turning around and walking in with the night god instantly, Kushina introduced the members of the research room by the way.

"Sister Tsunade and I, as well as Xiao Shizune, you all know each other, so I won't talk about it. These two are Tsuyoda, who is in charge of the auxiliary work, and Gukawa, who is in charge of preparing the experimental materials. ”

How to say it, there is an inexplicable sense of immediacy. The night god instantly had a feeling that he wanted to complain but didn't know how to complain.

"Wait, Sister Jiu Sinai, are there just a few of us?" Ye Shen instantly felt strange, saying that such an important research, is it really enough for just a few people.

"yes, how many more people would there be?" Kushina turned his head and glanced at the night god strangely, "How many people do you think are qualified to participate in this level of research work?" ”

Hearing Jiu Sinai's explanation, the night god nodded instantly, this kind of research of pure high-end content, many people can't participate, and it's normal to think about it. It's not about studying the Chakra cannon, there are a lot of people working on it, you don't see Uncle Snake just need an assistant in his pocket, and the others are experimental materials.

"So, what do I do?" The night god thought for a moment and asked.

"You wait." Kushina rummaged through the table, "Ha, I found it." ”

As he spoke, Kushina handed a thick document in his hand to Yagami. "This is the current research progress and information, and your task today is to take a look at this first, and get a good understanding."

The night god took the information instantly, nodded, found a chair, sat on it, and began to look at it.

After more than three months of research, Kushina and Tsunade naturally won't be without any results. In fact, the two have already completed the analysis of the Yin seal, and are already conducting experiments on the seal on the isolated tissue.

But the experiment has been stuck at this step for almost a month.

Therefore, before Kushinai found out that the weight equipment of the night god was hidden in the function that could store chakra, he was very excited.

"Sister Jiu Xinnai, didn't I seal the weight to you before? Why has there been no progress in the experiment for half a month? Night God was very surprised by the research situation, so he went to ask Kushina.

"Huh?" Kushina, who had carefully studied the information, was suddenly asked by the night god, and he couldn't react at once.

"Why have the experiments with sealing failed so far?" Night God asked again.

"Oh, your weight-bearing seal stores a portion of the chakra that the wearer emits during use in advance, and then plays a role when it is reversed, right?" Kushina understood what the night god meant, so he opened his mouth to explain.

"In other words, the storage effect of your Weight Seal is one-way, as long as it is applied to something that can store chakra. But this Yin Seal experiment, unlike your weight-bearing seal, the Yin Seal is a two-way chakra flow, and it can only be applied to living creatures. ”

The night god nodded instantly, slowly understanding.

"Our current problem is the material, the original plan was to use blood and hair, but the Yin Seal experiment on these two things has failed." Tsunade also walked over and joined the two in the discussion.

"And the use of metal, wood or scrolls are lifeless items, and they can't be sealed with a yin seal, and the only thing we can think of at the moment is to use a part of the body directly, but we can't just cut off a hand or a leg to use it." Kushina continued. "And we need a sufficiently reliable source of materials."

"So the problem is, we can't find some kind of living material to support the completion of the Yin Seal, right?" Yagami instantly understood what Kushina and Tsunade meant. "And we don't have a small demand for this material."

"That's right, that's the biggest problem right now." Kushina nodded.

"It doesn't seem like you can use an appendix or anything," Night God said to himself as he looked down and thought, "Can I use my wooden escape as a material?" ”

"Your Mu Dun, how is it possible, you are a transplanted cell, how can you exert a living Mu Dun? And the lifeless wood is more adaptable to chakra, what is the difference between it and ordinary wood? ”

Hearing Yagami instantly's words, Tsunade on the side retorted without hesitation.

"What?" Hearing Tsunade's words, Yagami was also stunned for a moment, saying that it was the first time he had heard of this. "What does it mean to have vitality?"

"It's a living wooden escape. Didn't you check your cell fusion last time, didn't you notice that all you make is wood, not living flowers and trees. If you want to reach that level, you have to cultivate well for many years. ”

Tsunade answered the question of the night god without hesitation, and in terms of what he knew about Mu Dun, Tsunade was the authority.

"But ......" Hearing Tsunade's answer, Yagami instantly felt very strange.

After a moment's hesitation, the night god instantly stretched out his hand and made a seal.

"Wood Escape: Inspired Flower Technique!"

A small pale blue flower bloomed in the hand of the night god.
