Not to mention how Iwakuin and Yunyin changed their mentality after being intimidated, and said that Rope Tree drove the Skywalker Fortress to the battlefield of the Earth Country and immediately headed south for the Land of Rain. He is very familiar with the thinking of the "smart people" at the top of the two countries, and is sure that they will definitely make the right and rational choice.

After entering the Land of Rain, the sky became overcast, and the fortress had to lower its altitude to sail low below the clouds.

But even so, the fortress also encountered all kinds of problems, and the dense rain clicked on the four purple flame arrays and made a "zizi" sound, and then was turned into steam by the high temperature. Not only does it affect the view of the fortress, but it also weakens the defenses of the enchantment.

Occasionally, thick lightning would fall from the clouds, shaking the purple barrier.

Rope Tree and the other high-level officials couldn't help but frown when they saw the situation outside the fortress through the light curtain.

The outer shell of the fortress is made of metal, and once the barrier is destroyed, it will inevitably attract a large amount of natural lightning, and the entire fortress will be in danger of falling.

Rope Tree looked at the bursts of thunder outside the light curtain, and finally spoke: "The harsh environment of the Land of Rain is indeed very unsuitable for flying. The Four Purple Flame Array is still too reluctant, let's open the Four Red Sun Array! ”

Orochimaru said with a smile on his face: "The defense of the Four Red Sun Arrays is certainly strong, but is the Chakra of Zero Tail enough?"

The corners of Rope Tree's mouth curled up proudly, and he said confidently: "Defenseless, just now Zero Tail absorbed a large amount of dark energy on the battlefield of the Earth Country, and the current Chakra can be opened for at least a few hours, which is enough for us to pass through the entire Rain Country." ”

After Zerotail's resurrection, the range of absorbing negative emotions has increased dramatically, and the absorption capacity has also improved considerably.

The reason why the Rope Tree wants to drive the fortress to the Land of Earth is not only to deter, but also to harvest the negative emotions accumulated by the civilians of the Land of Earth.

After absorbing a large amount of dark energy, Zero Tail not only stored a large amount of chakra, but also slowly increased the amount of chakra itself under the nourishment of dark energy.

Although Zerotail has the ability to absorb dark energy and chakra, there is also an upper limit to the amount of chakra itself, and it is not as much chakra as there is to absorb as many chakras. In the original book, Zerotail, who had just been revived, was killed by Naruto and Sasuke.

If you want to increase the amount of chakra of Zerotail, you must have sufficient energy nourishment to promote the growth of Zerotail's body, and both chakra and dark energy can achieve similar effects. However, since the core of Zerotail is a fragment of the primordial spirit, the effect of formless and qualitative negative emotions is better, not only is there no danger of being strangled to death, but it is also easier to digest and absorb.

After harvesting the negative emotions of nearly 100,000 ninjas and a large number of refugees in the land this time, Zerotail has stored a large amount of dark energy, and if he absorbs all the chakra amount, he will make great progress. It was a very luxurious act to maintain the Four Red Sun Arrays as a one-time energy, and if it weren't for the harsh sky environment in the Land of Rain, the Rope Tree would not have been so wasteful.

Although the growth rate of the Zero-Tail's clone chakra amount is a little small compared to his own proportion, this ability is still the envy of the Rope Tree's body.

Although the Rope Tree can also use the Wood Escape Blood to absorb chakras, it cannot use these chakras to increase its own chakra. If a ninja wants to increase the amount of chakra, they must improve their physical strength and mental will, so the vast majority of ninja chakra growth is slow, in addition to years of penance, they also need to be tempered by battle. What like Zero Tail can grow continuously by simply swallowing and digesting?

And what's even more enviable is that there is no upper limit to the amount of chakra of the zero-tail clone! As long as the energy is sufficient, the amount of chakra of Zero Tail can even exceed Ten Tails!

And the amount of chakra of ordinary ninjas will be limited by their own qualifications and bloodline, and it will be difficult to advance inch after cultivating to their own limit, even if the whirlpool and the thousand hands are born with a huge amount of chakra, but they also have their own upper limit, and with the aging of the body, this limit will decrease.

Therefore, there are few shadow-level powerhouses in the ninja world, and the achievements of ordinary people basically cannot surpass those with excellent qualifications, which is also the reason why the descendants of Kaguya's bloodline can always dominate the ninja world.

After entering the realm of practicing qi and transforming gods, the rope tree barely found a way to break the limit, and its potential is many times stronger than that of ordinary people, but practicing qi and transforming gods also has its own limit, and if you want to break through this limit, you must break through the bottleneck and enter the next realm, and you must also continue to cultivate, there is no shortcut.

Being able to use the body of the rope tree to increase the amount of chakra will temporarily lag far behind the zero-tailed clone, and it will be possible for him to catch up after the immortal reincarnation and cloning technology are perfected.

Of course, these details are only known to the rope tree that has trained Zerotail into an outer body, and the scientists of Orochimaru and Sky Country, who have studied Zerotail for a long time, also know it. And when it comes to rope tree's hole cards, he won't reveal them to anyone at will.

Except for Orochimaru, the people present were secretly frightened after hearing Rope Tree's words, Rope Tree was obviously sitting in the main hall, but he knew so much about Zero Tail's situation, which showed that his control over Zero Tail was very strong, and it was really unfathomable.

Since they have enough energy, of course they will not oppose the order of the rope tree, and they are also worried when they see the enchantment outside that has been cleaved by thunder and lightning, and it is a matter of their own lives, so naturally the safer the better.

After some manipulation, the Four Red Yang Array was quickly opened.

In the energy room, the zero-tailed clone felt the suction on the rune array suddenly increase, and tried his best to convert his reserve energy and increase the output of the chakra.

The huge amount of chakra was divided into four streams and rushed to the four corners of the fortress, where there was a huge complex magic circle, and after obtaining the chakra, it immediately began to operate.

The Four Red Sun Arrays were originally powerful enchantments that required the cooperation of their own shadow-level powerhouses at the same time.

If the amount of chakra exceeds four shadow-level powerhouses, it can also be used alone, for example, the ten-tailed Obito can use the higher-level Six Red Yang Array on its own.

The four formations arranged by the Rope Tree with a huge amount of precious materials can perfectly simulate the chakra movement of the four shadow-level powerhouses, and only need to input enough chakra to open the four red yang arrays.

"Hum", after the circle starts to operate, the new crimson enchantment will be wrapped, and the original purple enchantment will disappear.

The strength of the Four Red Sun Arrays is dozens of times that of the Four Purple Flame Arrays, except for the Ten Tails, even ordinary Tailed Beast Jade can defend against them, and the translucent Crimson Enchantment is as solid as gold, and the natural thunder and lightning of the Land of Rain are not shaken at all.

Even the raindrops and steam dissipated under the effect of the barrier, and the view around the fortress was clear.
