Yichen frowned, this bit of black substance was like a little dirty thing, very inconspicuous.

However, Yichen is the shadow of earth, and if this is an earth-like substance, it can be easily distinguished by Yichen's perception ability and soil escape level.

What's more, Yichen now has the blessing of the Immortal Mode, and his heart-eye perception ability is so powerful.

Being in the midst of an enchantment, even the enchantment that had been activated outside the laboratory to shield perception could not stop his eyes.

So although this little bit of black substance is inconspicuous, it still attracts Yichen's attention.

Yichen picked up the tool from the side and had to clamp the black substance into a glass bottle.

Unbeknownst to him, as soon as the clip touched the black substance, it began to move as if it were alive.

It actively detaches from the jar, falls to the ground, and then moves quickly in a certain direction.

In the eyes of Yichen and Starling Saki, this thing doesn't move very fast, and both of them can easily catch up with it.

But by the size of this thing, his speed is astonishing.

Yichen took the glass bottle, aimed the mouth of the bottle at the black substance that was quickly away, and said softly: "Vientiane Tianyin." ”

Remember http://m.et for a second

Then, the black substance, which seemed to be about to hit the laboratory wall, immediately broke away from the ground and was accurately inhaled into the bottle in Yichen's hand.

Yichen closed the cap of the bottle, looking at the black substance that was still wandering around in the glass bottle, constantly hitting the glass bottle, thoughtfully.

Yichen sealed and applied a five-element seal on the glass bottle, and the black substance immediately slowed down.

Although it is not motionless, it feels much duller, and it no longer hits the glass bottle.

"Affected by the Seal?" Yichen is not sure.

"Shaji, you go outside and call Katsu in." Yichen thought for a while and said to the little starling Saki.

"Okay." After Kostarling Saki agreed, he communicated with the enchantment class outside for a while.

Then, Katsu, who was maintaining the soul seal outside, came in again.

Yichen is very well prepared, not only Katsu is outside, but Atsumi Akinai, a professional who studies space ninjutsu, is also outside.

Yichen said to Sheng, "What level of soul seal can you cast?" ”

Katsu said, "It's much stronger than the seal that was submitted to the village last time, but it's still far from being compared to the seal of the shrine maiden. ”

Yichen nodded and said, "We don't have to compare with witches, they have a special physique, and there is no comparison. ”

"Come, I'll unlock the Five Elements Seal, and you can use your strongest soul sealing technique on it." Yichen pointed to the glass bottle in his hand and said.

"Yes." Victory and answer.

After a moment, Yichen looked at the motionless black substance, revealing a sneer.

The effect of the soul seal is greater than the attribute seal, and this black substance must be the soul.

"Sure enough, it's you, Black Jedi!"

That's right, this black substance is part of the body of the Black Jedi, which was originally attached to the jar to monitor the state of the jar.

Suddenly, Yichen's interest in the ghost fire was greatly reduced. He looked at the bottle in his hand and his eyes lit up.

What kind of hell fire is studied, where is it better than studying the body of the black Jedi?

Black Absolute is the representative of the ultimate yin in the ninja world. It may contain the secret of the path from mortal to immortal.

Kostarling Saki and Katsu both felt Yichen's violent ups and downs.

Both of them were a little surprised, in their eyes, although Yichen was out of tune, there was nothing that could make Yichen so excited.

Not to mention anything else, the two temples related to the two of them, Yichen did not show such strong emotional fluctuations at the beginning.

The two of them glanced at each other, and they both became extremely interested in the black substance in Yichen's hands.

Yichen cast the defensive enchantment again outside the glass bottle before taking it into his arms.

"Katsuya, as long as you research a stronger soul seal in the future, come to me as soon as possible to replace the seal outside this glass bottle." Yichen said to Sheng.

After hesitating for a long time, Yichen still decided not to study this part of Hei Jue's body first, and now his level was not enough.

At the very least, they had to wait for the victory, and their soul sealing research had made substantial progress.

At least to the extent that you can seal a shadow-level soul, and then you can study the soul seal first, and then start researching.

Otherwise, the risk is too great, and it will not be good if one accidentally lets it run away or is controlled by his sneak attack.

Black Jedi has this ability, and in the original book, it was even able to control the Uchiha Obito who had the eye of reincarnation.

Although this part of the body is not large, the level is there, so you have to be careful.

Sheng listened to Yichen's words again and immediately agreed.

Taking a deep breath, Yichen finally forced his attention on the jar.

After careful observation, Yichen came to a conclusion that this jar was very ordinary.

The material may be a little delicate, but it is not like the carving of the monk in the temple before, which is arranged with soul seals.

There is nothing on this jar, and its function is really a simple container, used to house the magical life inside.

After thinking about it a little, Yichen knew that he had fallen into a misunderstanding.

In the first temple, the role of the statue is supposed to be a seal, a suppression. That's why there was a seal on the carving, and there was a special seal on the temple.

But the second temple has a distinctly different function, and this temple is dedicated to this jar, to be precise, to the contents of the jar.

In the eyes of those believers, the jar is the gods, how can they impose a seal on the gods.

After thinking clearly, Yichen breathed a sigh of relief.

Without the seal isolation, the existence in this jar would not have much power. That's enough to say it's weak.

It seems to be overestimating the contents of this jar.

Yichen motioned for Katsu to go out with Starling Saki, and after leaving a shadow clone for himself, he also left the laboratory.

Then the shadow clone opened the jar alone.

"Whew." The shadow clone breathed a sigh of relief.

When the jar was opened, there was no earth-shattering monster, just a blue flame in the jar.

It's just that the next moment, the flame suddenly burst up and hit Yichen's head.

Although this is just a shadow clone, and its reaction power is far less than that of Yichen's body, the shadow clone has been vigilant about the danger in the jar.

So it was easy to dodge.

The blue flames didn't hit the shadow clone, and after a circle in the air, it slammed into the shadow clone's head.

The shadow clone quickly sealed his hands, and it was a C-level water escape against this blue flame.

Doused by the C-class water, the flames seemed to be in great pain, and they didn't dare to get any closer, and instead wanted to escape from the laboratory.

The shadow clone didn't stop it, wanting to see what special abilities this blue flame had.

But he was destined to be disappointed, the blue flame could not pass through walls, could not ignite other objects, and could not open or burst open the door.

As if it were just a harmless little flame.

But judging from its pounce just now, it is indeed full of malice towards the shadow clone.

It definitely has the ability to attack, but Yichen doesn't know about it yet.

After thinking about it for a while, Yichen cast a miniature version of Hao's Fireball Technique.

Since this blue flame is afraid of water escape, it is similar to a normal flame.

Yichen thought that it was also a flame, maybe it would be able to absorb the fireball technique and strengthen itself.

But Yichen thought too much, and after making contact with Hao's fireball, the blue flame shrank in a circle, and even the flight speed slowed down, obviously suffering a lot of damage.

Then Yichen used his various ninjutsu again, and found that these ninjutsu could attack the blue flame.

Oh, it might be more appropriate to call it a flame now, after being tested by Yichen for a while, although his body shape has not changed much, his brightness is significantly smaller.

After thinking about it, the shadow clone let the main body outside get some small animals.

As soon as a rabbit enters the lab, blue flames pounce on the rabbit's head.

The next moment, the rabbit began to struggle, but this struggle was not long, and the rabbit soon died.

When the blue flame came out of the rabbit's head, its color was noticeably brighter.

The shadow clone's eyes lit up, as if he understood something, and he lifted himself and passed his memories to the ontology outside.

Yichen's body hesitated slightly, then gave a few orders to Shengyou and the others, and then entered the laboratory.

Seeing that another life had come in, the blue flame pounced on Yichen's head again, but it was directly hit by a water escape and its light dimmed.

Next, Yichen threw another rabbit to Blue Flame.

As a result, the blue flame entered the rabbit's head, then came out again, and became brighter again.

Yichen took a deep breath, and this time he felt that the blue flame was forcibly absorbing the rabbit's soul.

Unlike the shadow clone, Yichen's body has enough Yin Escape level and sufficient perception ability, so he can roughly understand what happened after the blue flame entered the rabbit's body.

This blue flame didn't know what kind of existence it was originally, but now Yichen had only identified one of its abilities: devouring souls.

The blue flame ignited the rabbit's weak soul like firewood.

And the energy released after ignition is absorbed by it.

Very buggy ability, Yichen thought about the use of a lot of blue flames for a moment.

But no matter how you use it, there is a fatal drawback, and that is that the blue flame is too weak.

None of the ninjas who need Yichen to deal with them with means are weak, and this blue flame can't even get close to each other.

If this blue flame devours a certain number of souls, it may be strong enough to resist ninjutsu attacks.

But Yichen knew that this blue flame was uncontrollable, and it would hurt others and himself when he released it.

Keep it for now, maybe it will be of special use someday.

At least a part of Hei Jue's body was obtained, although the cost of building a laboratory was a bit large, but Yichen felt that it was not a loss.

Picking up the jar again, Yichen used the Vientiane Heavenly Attraction to suck the blue flames into the jar just like the part of his body that had just dealt with Hei Jue.

Gently close the lid, and the blue flame will no longer make any more noise.

This blue flame has little ability other than to deal with souls.

The ghost fire he created was most likely used for predation.

When this blue flame is strong, it is estimated that the ghost fire that can be separated can easily devour the souls of ordinary beings.

It only needs to stay in the jar to strengthen itself by devouring souls through ghostly fire.

But now Yichen is not afraid, in the current state of the blue flame, it is estimated that the ghost fire it separates can't even deal with a rabbit.

However, Yichen still sealed the jar very carefully.

After the incident, Yichen left the laboratory with the jar in his arms, and asked Katsu, who had been waiting outside, to put a soul seal on the jar.

Yichen patted the jar and said to the starling Saji, "Okay, it's okay here." This ghost fire looks like a flame, but it is not a flame, it has something to do with the soul. ”

"It's useless now, seal it first, and if you have special needs later, you can take it out and use it."

Starling Shaji nodded a little disappointed, she thought that she had encountered some special fire attribute energy, and she might be able to improve her flame escape through this flame.
