"Not bad! Listening to the system's prompt sound, Wang Kai nodded slightly, and then continued to look at the power of the three new soul skills!"

The soul skill of the Chaos World-Destroying Formation allows Wang Kai to summon the power of chaos from the Chaos Mountains and Rivers Cauldron to form a terrifying peerless killing formation. If Wang Kai's strength is strong enough, let alone a god, even the world can collapse, which is extremely powerful!

The soul skill of causality and effect allows Wang Kai to control the legendary law of cause and effect. This is one of the legendary supreme laws of the universe and has endless power. Even if Wang Kai can only borrow a little bit of causality and effect, he can benefit endlessly!

Through the law of cause and effect, Wang Kai also denied the enemy's attack from the "result" to invalidate the enemy's attack; he could deny the existence of the enemy from the "result" to directly erase the enemy...

The last one is the soul skill provided by Eternity and the Devouring Dragon to Wang Kai - the Devouring Heaven and Earth. As the eighth soul skill, its power is also very powerful. Once it is activated with all its strength, it can swallow and kill all the existences within a thousand meters. Only the strong man with the strength of the title Douluo can escape.

"Then, continue to improve these soul skills to 900,000 years!"

The new soul skills obtained by Wang Kai are all 100,000 years old. Wang Kai is not in a hurry to obtain the million-year soul ring, but plans to upgrade those 100,000-year soul rings first.

Upgrading the soul ring is definitely a long process. Therefore, Wang Kai also activated the "change time flow rate" function of the small plane, so that Wang Kai can practice in the small plane for three days, and only one day has passed on Douluo Continent.

It is true that Wang Kai has the "Power of Time" soul skill, which can achieve similar effects, but during practice, Wang Kai is not convenient to activate the "Power of Time" soul skill, and the "change world flow rate" function provided by the system is just right.

......

Five days in the small plane (corresponding to two days on Douluo Continent).

"Yes, all my soul rings have successfully advanced to 900,000-year soul rings!"

A look of joy could not help but flashed through his eyes, and Wang Kai nodded slightly, feeling extremely happy.

If you want to upgrade all the soul rings to 900,000-year soul rings, the system's gift after upgrading to Contra is far from enough. Even Wang Kai spent more than 10,000 points to exchange for the soul ring sublimation stone to complete the upgrade of the soul ring.

After refining so many soul rings, even if a soul ring sublimation stone is not helpful to Wang Kai, Wang Kai used more than 100 soul ring sublimation stones this time, which still increased Wang Kai's attributes by nearly 50%, and allowed his combat power to reach the ordinary level 97 peak Douluo, and to a new level.

"Let's have a good rest first!"

After refining so many soul ring sublimation stones, even with Wang Kai's mental power and physical fitness, he felt extremely tired. He wanted to relax and have a good rest.

Next, Wang Kai is preparing to upgrade all soul rings to millions of soul rings, that is, god-level soul rings!

During the Soul Saint period, Wang Kai's physical fitness was not enough to upgrade his soul ring to a million years, but as Wang Kai advanced to the Soul Contra, he already had enough abilities to have a million-year soul ring!

Of course, although Wang Kai has the ability to obtain the million-year soul ring, it is still not easy to upgrade the nine hundred thousand soul ring to the million-year soul ring, and Wang Kai needs to keep it in the best condition.

There is no need to say much about the solution to this point. In the small plane, there are two beautiful ladies, Mo Shu, Wang Xianer, and Yu Qingyue, Dugu Yan, two beautiful female slaves. After a day and a half-long game with them, Wang Kai also returned to practice with full spirit and was ready to start fusion of the million-year soul ring!

As the first million-year soul ring, Wang Kai naturally chose the soul skill of the mountains and rivers. Once this soul skill is upgraded, Wang Kai's recovery ability will be higher, and it will be easier to upgrade other million-year soul rings in the future.

Releasing the Chaos Mountain and River Cauldron Martial Soul Spirit, Wang Kai took out a 100,000-year Soul Ring Sublimation Stone, and then crushed it.

The same process, but this time, when the colorful mist enveloped Wang Kai's body, Wang Kai also felt a terrifying and irresistible pressure, which made his bones squeak and squeeze sound.

The million-year soul ring, also known as the soul ring of gods, generally speaking, this is a field that only gods can come into contact with. Wang Kai is now comparable to the peak Douluo, but he is just a mortal after all. It is naturally not easy to peek at the realm of gods with the body of a mortal.

If it is an ordinary peak Douluo, facing such pressure, he may only be able to last for a few dozen seconds and he will be seriously injured and fainted. However, Wang Kai is different. On the one hand, the power of mountains and rivers gives Wang Kai a powerful recovery ability. On the other hand, the five great martial souls give Wang Kai the most tenacious patience. As long as the pressure does not defeat Wang Kai, it can become the driving force for him to move forward and evolve!

......

Half an hour later!

"Persevere! Keep persevering!"

The body was endured by indescribable severe pain. Wang Kai felt that every cell was about to explode, and the tendons and veins were always experiencing tearing. Wang Kai's sea of ​​consciousness also had a strong sense of control, as if his brain was not his own.

Although Wang Kai has fully activated the bloodline of the Shura Emperor, and the power of other divine martial souls and mountains and rivers protect him, Wang Kai is still on the verge of coma many times in the face of terrible pressure. However, relying on his tenacious will and resilience, he survived again and again!

As time passed by minute by minute, the pressure and pain Wang Kai suffered slowly increased with the passage of time. At this time, Wang Kai's will and body were almost numb, and every minute and every second were extremely difficult, and it could be said that it was like a year.

Finally, an hour passed. At this moment, Wang Kai suddenly felt that the pressure surrounding him had stopped increasing, and the pain he felt began to slowly decrease. At this point, Wang Kai finally breathed a sigh of relief.

The previous hour was the most difficult process when upgrading the soul ring. Once you overcome this hurdle, the subsequent pressure and pain will not increase, and the process of upgrading the soul ring will be relatively good. The million-year-old god-level soul ring is already waving to Wang Kai.

Time passed minute by minute, and finally another hour passed.

"Huh! It's finally successful!"

He slowly opened his eyes. At this time, Wang Kai's surface was wet with beans sweat beads, and several blood marks had already bitten out of the corners of his mouth. His body, consciousness and tendons were also on the verge of collapse. Not to mention fighting, he was a little reluctant to stand up.

You know, Wang Kai is a strong man with the peak Douluo strength. It is enough to make him suffer so much that it is enough to show how difficult it is to upgrade the god-level soul ring. Even Wang Kai has gone through thousands of hardships to succeed.

"Ding! Using the sublimation stone of the 100,000-year soul ring, the third soul skill of the second martial soul Chaos Mountain and River Cauldron was successfully advanced to the million-year soul ring, entering the realm of the god soul ring, and the power of the soul skill mountain and river evolved into the power of heaven and earth!"
Chapter completed!
