The opportunity to use the 'Crossing the Spirit Abyss' is certainly a dream in the eyes of the scattered cultivators and the minor sect cultivators, and it is extremely cherished.

But as far as Zi Yutian knew, in a great sect like the Sun and Moon Xuanzong, there was no shortage of opportunities for his disciples to use the 'Crossing Spirit Abyss'.

There are even many 'Soul Crossing Abysses', but they are actually in a state of perennial vacancy.

These seven great Xuanzong only forcibly occupy these spiritual abysses and use them to extract all kinds of divine dew, and never give them to outsiders.

And like now, the situation that the seventeen 'Crossing Spirit Abyss' are crowded has never been seen in the past years of the Sun Moon Xuanzong.

This just shows that the talents of the Sun Moon Xuanzong are at their peak! How abundant are the top divine masters in the sect who are expected to be Holy Spirits to be able to fill the seventeen Soul Crossing Abyss twenty years later?

If you calculate the recovery ability of these Spirit Crossing Abyss, it means that at least ninety top-level divine masters are waiting in line to be promoted-

According to the success rate of 10 to 1, it is nine Holy Spirits!

"It's not as exaggerated as you think, very few of these divine masters can succeed at one time, and some people are just trying to comprehend the mystical law with the help of the spiritual abyss. But this is the only time in the past 20 years that you have been promoted to the Holy Spirit. It's not easy to get a place to use the 'Spirit Abyss' for a mere demon slave. The heavenly spirit abyss is even more rare."

After Zhang Xin said this, he smiled and asked again: "Anyway, to give you a chance to promote the Holy Spirit, there are so many words." Is the Jade Heavenly Prince planning to give up?"

"How is that possible? Just make it clear in advance, lest you regret it later!"

Zi Yutian snorted softly, and the luster in her sky-blue eyes was fierce: "You have to know that even if I am promoted to a god and demon now, I will not be able to build a law domain." ”

In order for the Holy Spirit and the Gods and Demons to build a legal domain, they must reach the Ninth Battle Realm. But now, she is still a thin line away from the realm of Fa Heaven and Earth.

The gods and demons who do not have a legal domain, that is, they live longer, and their combat power has not improved much.

"I didn't say you had to awaken to the realm now. Well, if you don't want to, then forget it—"

Zhang Xin said as he grabbed the oath in Zi Yutian's hand. The latter was a dodge, and when he was dozens of feet away, he carefully looked at the contents of the affidavit.

Zi Yutian found that this oath was no different from what Zhang Xin promised. The only problem is that the conditions for revenge are too broad. The oath doesn't say how far revenge will be taken before it can be completed—

But then she snorted coldly, and imprinted her own essence and blood into this oath.

Spiritual oaths are based on spiritual restraint and self-knowledge.

In other words, when one day she thinks that she has fulfilled her promise to Zhang Xin, she can naturally break away from the control of this spiritual contract.

Compared with her current time limit of several hundred years, the new slave contract provided by Zhang Xin is undoubtedly much more lenient.

And even if this guy doesn't keep his credibility, she can't fight it. Once promoted to the fifteenth level, she herself has the power to resist this unequal servile contract.

At this time, Zhang Xin was also a decisive and neat hand knot seal, so that the red mark in the center of Ziyutian's eyebrows spontaneously combusted without fire.

The new deed has been decided, and the old spiritual pact is no longer necessary.

Just as the two of them were renewing their spiritual contract, the bottom of the sea was already visible in front of them. The distance from the sea is exactly 2,400 zhang.

When he arrived here, Nagu Taiwei suddenly accelerated and came to the front of Zhang Xin, faintly guarding.

Zhang Xin saw it in his eyes and couldn't help but be silent for a while. Thinking of every time he encountered a battle in his previous life, Gu Taiwei did the same.

Although he changed his identity today, this guy still behaved the same, but what did he notice?

At this moment, Zhang Xin also felt the pressure from all directions around him. The invisible air shield beside him has been compressed to the extreme. Only a layer of air film remains, clinging to the skin,

Two thousand four hundred zhang, according to the calculation of the Federation, that is, more than seven thousand meters. This is already the domain of professional diving boats.

And in their Heavenly Dome Continent, even if it was a water avoidance talisman as high as level forty, when it reached this depth, it was extremely reluctant.

In addition to the water pressure, there are all kinds of deep-sea beasts cruising around them.

These beings are all huge, almost all of them are twenty zhang, or even forty or fifty zhang in size. None of them were below the sixth order, and they were in groups, even the smallest group was more than thirty or fifty heads.

With the strength of Zhang Xin and the six of them, it is not difficult to destroy these water tribes. But the problem is that if there is any noise here, it is likely to trigger a siege by sea beasts here.

And under the deep water, their cultivation can play six or seven percent, which is considered very good.

Thankfully, the eyesight of these deep-sea tribes is generally poor, and their inspiration ability is not seamless and seamless. On the contrary, their sense of smell and hearing is extremely sensitive. And the six people here are all experienced spiritual cultivators, and before entering the deep sea, they have already paid attention to restraining their own scents, and all the sound patterns have been restrained by their side.

There was still no trace of the abyss of the soul at the bottom of the sea, but none of the six of them had the slightest hint of surprise. At this time, they all looked up and looked ahead.

Thirty-five miles away, there was a huge submarine whirlpool. Not only is it swallowing the surrounding sea water with the momentum of whale swallowing, but the violent vortex is also sweeping the surrounding area.

Zhang Xin couldn't even stabilize his body, and could only rely on Zi Yutian's help to not be swept into this vortex.

But a moment later, Zhang Xin's body was covered with a layer of silver armor. He was also able to break away from the support of the purple jade heaven and stand alone in this vortex.

Long before Zhang Xin advanced to the Fifth Battle Realm, Ye Ruo had already designed a new set of Type 2 'Battle Saint Armor' for him.

However, due to the delay in mastering the 'Thunderbolt Type 7', Zhang Xin has not had time to practice until today.

At this time, the set of silver armor on his body was a set of special diving armor.

This armor is not only simple in structure, easy to master, but also theoretically up to 19,000 meters deep.

In addition to the pressure resistance, this armor also has a complete underwater survival system, as well as twelve groups of ion thrusters distributed in the hands, feet, chest, abdomen and back, which can sail at high speed underwater silently and flexibly adjust the direction.

In addition, this armor is even equipped with a set of underwater high-speed supercavitation propulsion system.

The so-called 'supercavitation' is somewhat similar to the wind-based spiritual technique 'water avoidance technique', but the principle is very different.

This is a physical phenomenon, when the object in the water movement speed of more than 185 km / h, its tail will form a strange large water vapor groove, the object and the water contact part of the package, the object contact medium from water to water vapor, because the air density is only 1/800 of water, so it can greatly reduce the resistance of the object, the surface of the object will form a large air bubble, this is the "supercavitation phenomenon".

Ye Ruo's 'underwater high-speed supercavitation propulsion system' is to create a gas cavity between the surface of the diving armor and the water, so that ships and other objects can advance in the gas cavity, and at the same time, a new gas cavity is generated while advancing, and the cycle repeats, so that the drag can be reduced and the speed of the diving armor can be increased.

The data given by Ye Ruo is that without any interference and with sufficient power, the speed of this armor can reach 1,700 kilometers per hour.

This may not seem like a lot, but it is important to know that this nail is used underwater.

At least as far as Zhang Xin knows, there are not many creatures in this world who can reach a speed of more than 6,000 miles in an hour.

In the future, if he encounters any critical situation, he can consider escaping from the water for his life.

"A few people have already guessed, and this seat will not waste time to explain. ”

Zhang Xin said as he threw five black chains in front of Sikong Hao and the others: "The vortex in this sea eye is extremely dangerous, and there are many forks in the road. In order to prevent separation, after you enter, remember to follow closely behind me, and you must not let go of this chain, otherwise you will bear the consequences!"

This time, it was not only Sikong Hao, but there was a slight suspicion in his eyes, but Lu Hua and Shen Shi behind him were also flickering. Obviously, there is a lack of trust in Zhang Xin's words.

A mere fifth-level spiritual cultivator can't even guarantee his own survival within the sea eye, so how can he have the strength to guide them?

Only Gu Taiwei has been expressionless, it seems that no matter what Zhang Xin wants to do, he will accompany him.

Zi Yutian knows a little about Zhang Xin's roots, and knows that this person relies on a thing called 'science' and has all kinds of strange abilities.

In Zhang Xin's case, no matter what happens, it is not surprising.

But at this time, Zhang Xin had no intention of continuing to explain, he directly activated several sets of ion thrusters located on his back, and rushed towards the direction of the whirlpool.

Just before those chains were taken away by him, the five of them all struck out one after another, clinging to the tail ends of the five chains.

And in the next moment, everyone felt a tremendous force coming from above the iron chain, pulling them forward.

This was partly due to the vortex, and partly from the silver figure in front of it.

And after rushing into the eye of the sea, everyone's feelings are even more obvious. In this violent whirlpool, it is as strong as commonplace, and there is also a sense of involuntariness. The chaotic psionic tide here also made it impossible for him to cast spiritual magic outside the water system.

But Zhang Xin can swim calmly in this, and he can easily adjust the direction in the turbulent tide, and resist all kinds of pressure and suction from all directions that can forcibly tear any tenth-level spirit beast apart.

Is this silver armor?

While Sikong Hao took a step closer and grabbed the chain, he took a deep look at Zhang Xin's silver full-body armor.

At this moment, he remembered the battle of Luye Mountain, the detonation that originated from the ground. There is also the iron bird that collided with the nighthawk that I saw before.

He now felt that the star-picking envoy in front of him, as well as Shangguan Xuanhao, who had never been able to meet, were becoming more and more unfathomable.

And at this time, it was within Zhang Xin's horizon. Ye Ruo also exclaimed.

"Master, do you see there? What is that? How can there be such a thing? This is so unscientific—"
