The cultivation and implantation of the 'ghost bud' is far more troublesome than the imagination of the Hyuga Mirror.

And Hyuga Mirror didn't dare to experiment with his body casually like Beiliuhu, after all, his Yin Escape Buddha was the core of everything, if his Yin Escape Buddha was irreparably severely injured before the achievement of the Blood Relay Snar, then his attempt to impact the Blood Relay Snar, would be shattered.

"Fortunately, Shennong was controlled in time..."

After closing the scroll of the 'Oni Nyora's Technique', Hinata Mirror secretly rejoiced.

When Shennong defected from the Xiao organization, he swept away a large number of test materials and instruments from Beiliuhu, and after the successful attack on Shennong, he not only received the air fortress of the empty ninja and a large amount of property and equipment, but also obtained a large number of materials and instruments related to the 'Ghost Bud Luo' that Shennong took away from Beiliuhu, as well as some test records of Shennong's own cultivation of 'Oni Bud'.

With these, it is much less difficult for the Hyuga Mirror to cultivate the 'Oni Bud'.

After all, he already has an unusually rich experience in human experiments, and now that he has materials, instruments, and even experimental records, if he can't cultivate 'ghost buds', then it's better to die.

The cultivation of 'Ghost Buds' is not something that can be successfully achieved in a short period of time, so although Hyuga Mirror has not yet gathered all six clones, the cultivation of 'Ghost Buds' must be put on the agenda.

After making up his mind, Hyuga Mirror first went to the Shadow Base for a walk, and after confirming that there was no special task in the Shadow Department today, he left a shadow clone in the village, and then the deity quietly sneaked out of the village, entered the reincarnation eye chakra mode, and flew into the air fortress suspended thousands of meters in the air.

Walking in the corridor of the Sky Fortress, Hinata couldn't help but frown.

After experiencing the initial surprise and emotion, he gradually discovered that many areas of this air fortress were decayed and damaged to varying degrees.

For example, the current corridor leading to the central hall has many stone walls on both sides of the road, and there are even areas of collapse in several forks.

In addition to the obvious decay and damage to the internal structure, the power transmission system, which is the core part of the air fortress, also has serious problems.

In particular, the output power of the two magnetic drives at the end of the fortress is inconsistent, and the power of the one on the left is obviously much stronger than the one on the right.

This also directly leads to the air fortress in the flight, is not stable, there is a more serious turbulence phenomenon, and the fortress every ten kilometers, there will be about 5 degrees of direction deviation, the operator needs to frequently correct the flight direction of the fortress, in order to ensure that the fortress in flight will not deviate from the established course.

"It looks like the repair of the fortress is also on the agenda..."

Hinata Mirror said secretly as she walked.

Now this air fortress has become his secret base, there is no room for any mistakes, so proper maintenance, is essential, he does not want this fortress to become a super weapon in a short time, he only hopes that this air fortress will not fall suddenly due to disrepair, causing his secret laboratory to be affected.

Coming to the cabin where the secret laboratory was housed, Hyuga checked Shennong's own list, counted the materials and instruments that Shennong had taken away from Beiliuhu one by one, and classified them into categories and rearranged them according to his own usage habits.

After rearranging it, Hinata Mirror immediately began to experiment with cultivating 'oni buds'.

Because there are a large number of ready-made 'sprouts', Hyuga only needs to extract his own cell tissue, and then plant the 'sprouts' into his own cell tissue, and the 'sprouts' that can survive are the 'ghost buds' that can fit his body.

According to the experimental records of Beiliuhu and Shennong, the probability of directly planting 'sprouts' into the body and cultivating 'ghost buds' that fit with oneself is the highest. In the case of the Hyuga mirror, the probability of successfully cultivating a 'ghost bud' that fits itself by extracting the cell tissue and then using the 'bud' in the cell tissue will be very low.

But despite this, Hinata decided to use cell tissue to cultivate 'oni buds'.

After all, the uncontrollable risk of planting the 'sprouts' directly in your own body is too great, and no one can say what kind of mutations will occur to the 'sprouts' planted in the body, and what changes will be brought to the body.

In order to increase the probability of successfully cultivating 'ghost buds', Hyuga Mirror put its own cell tissues into 100 petri dishes, and planted 'ghost buds' in all of these 100 petri dishes at the same time.

He believed that as long as his luck was not too bad, one or two 'ghost buds' that fit with him should be cultivated in these entire hundred petri dishes, and as for the implantation process that was more troublesome than cultivation in the future, it was not something he needed to worry about at the moment, at least until he had cultivated all six clones, and then he needed to think about it.

Over the next week, Hyuga spent the next week monitoring the cultivation of the 'Oni Bud' and surveying the damage to the Aerial Fortress.

The cultivation of the 'Ghost Bud' took three to four months, so in just one week, there was no result, but after a week of careful investigation, Hyuga Mirror found that the situation of the Aerial Fortress was more serious than he imagined, and it was necessary to land in an open field and carry out a large-scale repair to ensure that there would be no accidents in the Aerial Fortress.

So he disguised himself and disguised himself as a different identity, shuttled through the major countries of the ninja world, bought a large number of building materials in various places, and then landed the air fortress in a remote and flat desert in the land of the wind.

The maintenance of such a large building involves many fields, and the repairer needs to have a lot of experience just to investigate where the problem is.

Hyuga naturally has no relevant experience, but he has white eyes, so where there is a problem in the air fortress and where it needs to be repaired, he only needs careful observation to easily find out the problem.

Coupled with the assistance of the three generations of Wind Shadow puppets from the side, it only took him two weeks to replace and repair the decayed parts of the air fortress.

As for the power transmission system of the Air Fortress, the Hyuga Mirror has not been completely understood at present, so he does not dare to repair it indiscriminately.

At present, after the repair, the internal structure of the air fortress has been stabilized, and there will be no accidents of falling or disintegrating from the air without being attacked by foreign enemies, but there are still problems with the power system of the fortress, which is not suitable for frequent long-distance movement, and it is best to hover in one place, and it is safest not to move easily...
