I set off a natural disaster in the ninja world

The sun rises and sets, and in the blink of an eye, half a month has passed.

Luo Lin's experiment has entered the final stage, and he is only one step away from controlling the Four Tails.

During this time, his other plans were also progressing well.

About ten days ago, Hades Warrior No. 6 completed its mission and returned to Luo Lin with fifty skeleton mages.

Returning with them, there were more than 5000 bones and skeletons, which suddenly expanded the number of bones and skeletons in Luo Lin's hands to more than [-].

Of course, this process has not been smooth sailing.

Just as Luo Lin expected, there was indeed someone watching there, an ANBU team from Iwagakure Village.

However, with the expert Ryoma Aburame, they were unable to escape, and eventually became Luo Lin's slave No. 3, and three zombies with three-star potential.

After ten days of accumulation, all three zombies evolved into death claws.

Not only them, but three of the four zombies Luo Lin summoned before also evolved into death claws.

Although after evolution, their potential has been reduced by half a star, they still have the potential of two stars and two and a half stars.

With such potential, the probability of evolving into a Hades Warrior is not too low, so it won't be long before Luo Lin's men will have a few more Hades Warriors.

In addition, after half a month of development, the slave team has also grown from two people to five people, and Luo Lin has been provided with thirteen good materials.

Luo Lin had taken the time to summon them into zombies, but the time was still short and the evolution level was not accumulated enough, so they failed to evolve.

In addition to zombies, in the past half month, the evolution degree of Luo Lin's skeleton warriors and skeleton mages once again accumulated to 100%, and they tried to evolve.

However, since they failed once before, their potential was reduced by half a star, so the success rate of this evolution is even lower.

There are a total of 91 skeleton warriors with a star level or above, and only 22 have successfully evolved into skeleton warriors.

As for the remaining skeleton warriors, their potential has been reduced by half a star again, and they have basically lost the possibility of evolving again.

Similarly, of the sixteen low-level skeleton mages, only five successfully advanced.

In this way, Luo Lin's undead become like this:

冥武士：4个；死亡之爪：9个；僵尸：14个；僵尸·虎：1只；僵尸·乌鸦：5只；骷髅法师（中阶）：39个；骷髅法师（低阶）：11个；骷髅勇士：111个；骷髅战士：117个；白骨骷髅：8120个。

Unfortunately, except for the Hades Warriors, the other undead would not be of any help to his next actions.

Luo Lin didn't think Danzo, an old bastard, would attack his undead army just to capture the Four Tails.

Even, in order to reassure Danzo, Luo Lin would not let a group of undead get close to the scheduled battle location when taking action in the future.

As a result, the power he can use is very limited.

Fortunately, his experiment has entered the final stage.

Glancing at the nearby Hades warriors and slaves, Luo Lin ordered: "Be alert!"

"Yes!"

After everyone responded, they ran in all directions skillfully.

After they left, Luo Lin said to Lao Zi in front of him: "Let's start!"

Lao Zi nodded seriously and took off his shirt quickly.

Then, he formed a seal with his hands and tore a gap in the seal on his body.

However, with just such a gap, the chakra of the Four Tails surged out like a tide.

Just then, a dark red chakra like flame appeared on the sealing technique on Lao Zi's abdomen, and then spread to his whole body at an extremely fast speed.

In just the blink of an eye, four tails appeared behind him.

During this process, the four tails continued to impact Lao Zi's consciousness, seeming to want to control him.

Seeing this, Luo Lin's mental power dispersed, magic power surged out, and a moment later, a ten-meter-wide magic circle appeared at his feet.

This is what Luo Lin achieved in half a month.

Referring to the advanced knowledge of runes, he created a magic circle.

This formation has two main effects, one is to suppress the alien energy within the range, and the other is to temporarily strengthen his mental power.

Just like now, as soon as the magic circle appeared, the activity of the tailed beast chakra in Lao Zi's body was reduced by a level, and the erosion of him was also reduced.

However, Luo Lin didn't pay attention to this. He had to hurry up and take the next step.

This magic circle is not very perfect. When it is turned on, the consumption of mana is very scary. Even if his mana limit has been increased to 8290 points, it still cannot last 5 minutes.

Thinking of this, Luo Lin slapped the sealing technique on Lao Zi's abdomen.

As soon as they made contact, the tailed beast's chakra enveloped his palm and quickly eroded his flesh and blood.

At this moment, Luo Lin felt as if he had been slapped on a red-hot iron, and there was a burning sensation all over his palm.

Holding back the pain, Luo Lin's mental power penetrated the space where the tailed beast was sealed along the gap that Lao Zi had torn open.

"Damn it, it's you again! I won't give in!" As soon as he entered the sealed space, Luo Lin heard the furious voice of the fourth tail, "Die to me~"

In his field of vision, a fist covered with red hair quickly grew in size, but Luo Lin didn't blink and just looked at the opponent quietly.

"Bang~"

A dull sound came, and the fist stopped in front of Luo Lin.

"Ah~, damn it! Damn it!! Damn it!!! Bang~bang~bang~"

The four tails kept waving their fists, but they were blocked by a layer of water curtain. On top of the water curtain, there was a talisman.

When Luo Lin entered this place for the first time, he was indeed startled by the four tails, but he soon discovered that the other party could not hurt him at all.

The water curtain in front of him is the seal of Yanyin Village. As long as Luo Lin does not take the initiative to remove the talisman on it, the four tails will not be able to break through the seal.

Similar to the Nine-Tails, the Four-Tails' space for movement is also very limited, basically a small area behind the water curtain near the two boulders.

Seeing the incompetent and furious red gorilla, Luo Lin didn't waste any time. He skillfully used his mental power and began to forcibly conclude a master-servant contract.

The moment he took action, the magic circle came into view and appeared at Luo Lin's feet.

Seeing this, the Four-Tails immediately stopped venting and shouted: "Damn human, don't even think about enslaving me."

After saying that, it concentrated on fighting against the black patterns that appeared out of thin air on its body.

It has become very proficient in this kind of thing. In the past half month, it has successfully resisted more than 20 times, so it is not too afraid.

For a moment, the sealed space became silent.

What follows is a battle of spirit and will.

In the past, it was Luo Lin who failed in the end.

This is not to say that his spirit and will are inferior to the four tails, but that there is not enough time and he has no time to control the contract to take shape.

However, that may not be the case this time.
