The remnants of the Uchiha are forced to save the ninja world.

Chapter 500 It's still useful to keep it!
Everything was as expected, the aging medicine developed by Tsunade took effect, and the effect of stimulating accelerated cell division was transmitted from the docked tail all the way to the ghost's body, causing the ghost's body to begin to rapidly divide cells.

Swish.
The mechanism was activated, and the artificial blood vessel connecting the docked tail and the body was cut off instantly.

Tsunade ordered again: "Real-time report data!"

Yakumo hurriedly shouted: "The cell division of the experimental body is still accelerating, and it has broken through 1700%, and the effect of the aging potion is still taking effect."

On the other side, the medical ninja monitoring the ghost body shouted: "After the cutting is completed, the data of the 'monster' has begun to recover."

Not all the flesh and blood of ghosts can be separated from the main body.

Just like the ghost in the laboratory in front of me, once the severed limb is separated from the body, the severed limb will quickly wither like a flower under the scorching sun, so the broken tail that is the experimental subject will soon wither after the artificial blood vessel is cut off Down, lost the meaning of continuing to observe.

After counting all the data of this experiment, the scientific research team started the meeting.

Tsunade was the first to speak: "Judging from the data of this experiment, our direction of developing aging medicine is undoubtedly correct!"

"Great!"

The group cheered in unison.

In particular, the faces of several pharmacy experts who were chartered to join the scientific research team were full of joy.

Tsunade raised his hand to signal everyone to be quiet, and then continued: "Although this test has confirmed the effectiveness of the aging medicine, the current medicine effect is not ideal, and it is difficult to achieve a decisive effect on the battlefield. We still need to continue Improve the efficacy of the medicine!"

Everyone nodded.

According to this experiment, calculated from the peak potency of the aging potion, plus the loss of blood and flesh energy due to cell aging, the ghost who has been hit by the aging potion is equivalent to aging for more than ten or twenty years in one minute.

For an ordinary person, almost half his life is gone.

But for ghosts with high-speed regeneration ability, it can only be weakened to a certain extent, but cannot be killed.

At this time, a senior medical ninja raised his hand and said: "Master Tsunade, our pharmacy class has a new idea about the improvement process of aging potions. According to estimates, the improved Type II aging potion can On the basis of a type [-] aging medicine, the potency has been increased by at least ten times."

Then, another medical ninja raised his hand and said, "We can also improve the injection method, increase the instantaneous injection volume, and more than triple the amount of medicine injected into the target unit."

Tsunade nodded lightly: "Very good, you start improving immediately!"

Shizune suddenly said: "Master Tsunade, continue to experiment with severed limbs, I'm afraid it will be difficult to test the ultimate efficacy of the aging potion!"

As soon as Jing Yin finished speaking, everyone subconsciously looked at the ghost locked in the center of the laboratory.

Using severed limbs to test the aging potion can't really measure the weakening ability of the aging potion on ghosts, so if you want to get real data, you still need to test it directly on ghosts.

However, it took the village a lot of effort to catch such a ghost. If one was accidentally killed, many subsequent experiments would have to be interrupted.

So even if Shizune knew that what Shizune said was right, Tsunade could only shake his head helplessly: "There are too many secrets hidden in the 'monster', we can't directly test the 'monster' with aging potions, that would be dangerous. It may cause us to completely lose the experimental subject."

Shinji who attended the meeting secretly smiled.

The lack of test subjects for aging medicine is indeed a big trouble for the current scientific research team, but it is not a problem for Shinji.

But he is not in a hurry now, the current type [-] aging medicine is far from enough.It can only play a certain weakening effect on ordinary ghosts, not to mention targeting the king of ghosts, I am afraid that it will have no effect if it encounters a 'winding ghost'.

What Shinji needs is the kind of aging potion that can completely weaken the mysterious person who has the 'power of the ghost king'.

In the blink of an eye, another week has passed.

During this week, Shinji's various plans were steadily advancing.

He found the right time and drew Sasuke's chakra again to ensure that the pair of eternal kaleidoscope writing sharing eyes in Xianglin's eye sockets could be continuously nourished by the 'power of all phenomena'.

The Tenseigan chakra absorbed from the moon was also absorbed by Ningci several times during this period, and every drop of the seal was stored in the half of the "biological exoskeleton" on Ningci's body.

As for Tsunade's scientific research team, the pharmacy team worked overtime, and finally completed the research and development of Type II aging medicine.

It's just because the village hasn't caught any new ghosts yet, and there are no suitable test subjects, so the drug test of the Type [-] aging potion has been postponed for the time being.

Outside Konoha Village.

Under the moonlight, Dragon Tongue met with Xianglin at the agreed place as usual, and reported to Xianglin the information he had inquired from Cao Ninja Village this week: "Boss, all forces are currently secretly arresting 'Shangxian' 'That group of monsters, it is said that some monsters have been captured alive and sold on the black market."

Xianglin frowned slightly.

As Shinji's "waiter", she knows that there is pollution on the ghost. Although Shinji told her that the pollution can no longer be removed, she still instinctively couldn't help but frowned when she heard that the ghost was being secretly hunted down by various forces. He frowned.

Dragon Tongue continued to report: "There are rumors that Yanyin discovered the traces of the 'Shangxianzhizhi' and launched a campaign to encircle it."

Xianglin asked: "And then?"

Dragon Tongue shook his head: "There is no news after that, Yan Yin kept secret about this battle. According to the report we just put into Yan Yin, Yan Yin recently issued a huge amount of pension. Besides, there is no other The news is out."

"Okay, go back!"

After sending away Dragon Tongue, Xianglin immediately reported the news to Shinji.

Shinji shook his head when he heard the news.

Yanyin's encirclement and suppression of the "Shangxianzhizhi" obviously failed.

Ninjas are getting familiar with ghosts, and ghosts are also adapting to ninjas, especially the best of the ghosts such as "Shangxianzhiyi" and "Shangxianzhizhi". Before they became ghosts, they were excellent swordsmen themselves. , has cultivated the 'breathing method' to a very high level, and can mobilize all the strength of the body. Even without the ghost's almost immortal body, it is an extremely difficult existence to deal with.

After becoming ghosts, they have almost turned into killing machines made of flesh and blood. It is not an easy task to exterminate such ghosts.

Xianglin asked for instructions: "My lord, let me do it!"

Shinji waved his hand: "Don't worry, these ghosts are still useful for me to keep!"
