And above the 900,000-year soul ring, it is naturally the legendary million-year soul ring. However, although Wang Kai is very sure that once he upgrades the power of mountains and rivers to the million-year soul ring, the power of mountains and rivers will definitely evolve again, but he did not rashly upgrade the power of mountains and rivers to the power of mountains and rivers.

The reason is very simple. When Wang Kai evolved the power of mountains and rivers into a 900,000-year soul ring, he felt great pressure, and that pressure was approaching the limit of Wang Kai's body.

The million-year soul ring, also known as the God's Soul Ring, if you want to upgrade the soul ring to this level, although it only enhances the soul ring cultivation for 100,000 years, compared with the 800,000 to 900,000 years of upgrading and refining, Wang Kai will be at least ten times more pressure. For Wang Kai now, his physical fitness is not enough to support him in upgrading the soul ring to 100,000 years.

"It's a pity that I can't have a million-year soul ring. I guess I have to wait for me to upgrade to the Contra to try it! However, although I can't upgrade to the million-year soul ring now, I can continue to upgrade to the other soul rings first!"

Wang Kai was also quite regretful about not being able to have a million-year soul ring. However, Wang Kai also has a good use for the remaining source points. With these source points, Wang Kai can first upgrade the soul rings of his other martial souls and upgrade them to 900,000 years!

With a thought, Wang Kai continued to sit cross-legged, took out a hundred thousand-year soul ring to ascend to the stone, crushed it, and the colorful mist lingered. Wang Kai also held his breath and concentrated, eliminating all distracting thoughts in his heart, guiding these colorful mists into the tendons and veins, and began to ascend to the soul refining ring.

One week later.

"Very good. The seven soul rings of Shura Emperor have successfully upgraded to 900,000 years! Now, my strength has also reached a new level!"

The Shura Emperor martial soul was released, and seven red soul rings floated behind Wang Kai. Each soul ring had nine gorgeous and complex patterns, and a faint golden light was revealed. Correspondingly, Wang Kai's source points were also reduced to about 2,000 points.

During this week, Wang Kai naturally did not upgrade the soul refining ring, and also took into account both cultivation and hunting. When his soul was exhausted, Wang Kai did not forget to have a wonderful game with Moshu and Wang Xianer, which can be said to be extremely fulfilling. Finally, Wang Kai completed the upgrade of the seven soul rings of Shura Emperor's martial soul.

After refining the seven soul rings to 900,000 years, Wang Kai's attributes also increased greatly, almost twice as much as in the past. Wang Kai's strength also increased, reaching the top ninety-two-level titled Douluo. At the same time, Wang Kai's soul power crystallization level has been increased to 37%.

As for the soul skills, after being promoted to the soul skills of 900,000 years, the power of Wang Kai's seven soul skills will naturally be greatly improved. Fortunately, Wang Kai's total soul power has also increased a lot with the upgrade of the soul ring. He also has the power of the earth, so he will not fall into a situation where his soul power is insufficient.

After advancing to a soul skill of 900,000 years, Shura Blood Claw also evolved into Shura God-Slaying Claw, and its power increased by nearly three times. As for other skills, although they did not undergo a thorough evolution, they all increased their power. Not only that, Wang Kai's talent field, Shura Realm, has also become more powerful with the upgrading of the seven soul skills.

"So, now is the time to hunt other soul beasts!"

After this period of hunting, all the high-level soul beasts in the area ruled by Tai Sui Purple-Skinned Rabbit were basically cut off by Wang Kai, and the remaining low-level soul beasts also fled in scattered, which was not conducive to Wang Kai's efficient hunting, so Wang Kai was also preparing to kill the next soul beast among the nine emperors.

Wang Kai’s choice this time was the Purple Lightning Baizhang Deer, which also belongs to the weaker soul beast among the Nine Emperors. However, compared with the Tai Sui Purple-Skinned Rabbit, the Purple Lightning Baizhang Deer is undoubtedly much stronger.

If the strength of the Tai Sui Purple-Skinned Rabbit is probably equivalent to the weakest level ninety-first-level title Douluo strongman, then the purple lightning Baizhang Deer is equivalent to the weakest level ninety-second level title Douluo's strength, and the strength difference is very large.

Before Wang Kai became the soul refining ring, Wang Kai's strength was even weaker than the purple lightning Baizhang Deer, but with the emergence of the seven 900,000-year soul rings, Wang Kai's strength also improved by leaps and bounds. Now Wang Kai can definitely kill the purple lightning Baizhang Deer.

After making up his mind, Wang Kai also left the sphere of influence of Taizisie Rabbit and rushed to the sphere of influence of Zidian Baizhang Deer.

A few hours later.

After a while, the purple lightning hundred-foot deer had appeared in front of Wang Kai.

Still dozens of kilometers away, Wang Kai had discovered the purple lightning deer. As the beast was named, the body of the purple lightning deer was as high as a hundred meters, like a purple mountain range. There were terrible purple lightning walking around his body. Every time he struck, he could break out a charred pit on the ground.

"What a huge soul beast!"

Looking at the purple lightning Baizhang Deer in front of him, Wang Kai couldn't help but sigh that before facing the purple lightning Baizhang Deer, the largest soul beast that Wang Kai killed was just a giant ape as high as 30 meters, but the giant ape seemed extremely short in front of the purple lightning Baizhang Deer.

However, in the magical Douluo Continent, such existence is not surprising. Moreover, Wang Kai also knows that the Purple Lightning Hundred-Zhizha Deer is not the largest soul beast. The real body of the Deep Sea Demon Whale King is 1,000 meters long. Compared with the Deep Sea Demon Whale King, the Purple Lightning Hundred-Zhizha Deer is still a witch.

Of course, facing this huge purple lightning hundred-foot deer, Wang Kai did not show any panic on his face.

In the soul master world, being bigger does not necessarily mean being stronger. Although Wang Kai is dozens of times shorter than the Purple Lightning Baizhang Deer, Wang Kai is not inferior to the Purple Lightning Baizhang Deer in front of him, and even surpasses it in terms of energy level or momentum.

"Beast, be my resource for continuing to advance!"

Continue to fly forward and know that he has arrived at the area within a hundred meters of purple lightning, Wang Kai also stopped.

"Shura's true body!"

The soul power was activated madly, and the soul power in his body poured into the soul ring behind him like a spring. Suddenly, the seventh red soul ring behind Wang Kai suddenly shone. There were nine complicated and gorgeous patterns on the soul ring, and a faint golden color was revealed.

As this 900,000-year soul ring appeared, Wang Kai's momentum also skyrocketed wildly. Immediately afterwards, a little red glow with gold in the red gushed out from the soul ring behind Wang Kai and shot towards Wang Kai's eyebrows.
