After the hunting for half a month, Wang Kai's source points also grew rapidly, quietly increasing to nearly 8,000 points.

"Now, it's time to upgrade your strength again!"

Looking at the source points that were abundant again, Wang Kai also showed a hot look in his eyes. The eight thousand source points were enough to help his strength reach a higher level.

In the Tianheng Mountains, except for the Tai Sui Purple-Skinned Rabbit that Wang Kai just killed, the other eight 90,000-year-old soul beasts are even stronger. Wang Kai must improve his hard power to ensure that they are killed one by one.

"The power of the continent is you!"

As the root of Wang Kai's strong battery life, the power of the third soul skill of Wang Kai's second magical martial soul is naturally the primary target of Wang Kai's upgrade. Only when the battery life is strong can the combat power of Wang Kai's four magical martial souls be fully utilized.

The power of the continent for 300,000 years can completely restore Wang Kai's soul power in about half a minute. For ordinary soul masters, this is already very powerful, and it is also a recovery speed that countless soul masters can never dream of.

However, for Wang Kai now, if he releases a 100,000-year soul skill with all his strength, it will consume 100,000 to 20% of the soul power. If it is a 100,000-year soul skill, the soul power will be consumed even greater. Therefore, for Wang Kai, who has four great martial souls who can use it for 34 points, although the recovery ability of the power of the continent is good, it is not strong enough.

In addition, there is another limitation on the power of the continent. Although compared with the power of the earth, the power of the continent has escaped the limitation of the soul master having to stand on the ground when it is released. As long as the soil elements are thick, it can be released, but if it is in a place where the power of the continent is thin, such as on the Hell Road or the Sea, the effect will be greatly reduced.

Wang Kai's next stage enemy, Tang San, is the inheritor of the Sea God. Tang San has now gone to the Sea God Island for the Sea God assessment. With Tang San's qualifications, the Nine Sea God Tests must have begun. Therefore, the duel between Wang Kai and Tang San is likely to happen on the ocean. By then, the power of the continent will definitely appear weak.

To sum up, the power of the continent is a skill that Wang Kai needs to upgrade very much. Therefore, Wang Kai also spent source points to exchange for the 100,000-year soul ring sublimation stone, then sat cross-legged, released the Chaos Mountain and River Cauldron martial soul, and began to refine it.

As strong as Wang Kai, he continued to sublimate the 300,000-year soul ring, which can be said to be without any pressure. After a few hours, the two soul ring sublimation stones were consumed, and Wang Kai's continental power was also successfully advanced to the 500,000-year soul ring, which was the same level as the Destruction Power of the Eye of Creation.

With the upgrade of the soul ring, the effect of the power of the continent has also been upgraded again. In the past, the power of the continent took 30 seconds to restore Wang Kai's soul power, that is, about three percent of the soul power is restored every second. After the upgrade, the power of the continent can only take ten seconds to restore Wang Kai's soul power.

Recovering Wang Kai's soul power in ten seconds is to restore ten percent of the total soul power every second. Intuitively speaking, it is the soul power that the power of the continent restores Wang Kai every second, which is enough for Wang Kai to release a 100,000-year soul skill that consumes less, which is extremely against the will of heaven.

Not only that, the power of the continent can not only restore Wang Kai's soul power, but also restore Wang Kai's vitality and mental power. Even if Wang Kai is seriously injured and his vitality is less than 10%, he can recover in just a few seconds, which will maximize the protection of Wang Kai's survival ability.

After the power of the continent has advanced to 500,000 years, Wang Kai also had a vague feeling that if the power of the continent continues to upgrade, when it reaches the soul skill of 700,000 years, it will transform again and complete its complete evolution.

"Since that's the case, I'll advance again!"

He took out an adaptive 100,000-year soul ring again, and Wang Kai held his breath and began to refine it. Wang Kai did not feel any pressure on this process, but could perfectly guide the power of the adaptive soul ring, which was the most perfect upgrade of his soul ring.

A few hours later.

"Ding! The third soul skill of the second martial soul Chaos Mountain and River Cauldron uses adaptive soul rings and successfully upgrades to the 700,000-year soul ring. The power of the soul skill continent evolves into the power of mountains and rivers!"

Accompanied by the system's prompt sound, Wang Kai also opened his eyes excitedly, his face full of surprise.

As expected, Wang Kai did evolve after upgrading to the 700,000-year soul ring, and the evolutionary effect also made Wang Kai very satisfied.

First of all, after evolving into the power of mountains and rivers, this soul skill has completely escaped the limitations that can only be used on the continent. The power of mountains and rivers, whether it is the earth element of the earth or the water element of the lake and sea, can be absorbed and transformed. In other words, except for the extremely special field of Hell Road, the power of mountains and rivers can operate smoothly in almost all other places.

Secondly, it is the recovery effect. After evolving into the power of mountains and rivers, the power of mountains and rivers pouring into Wang Kai's body every moment is so strong that it only takes three seconds to completely restore Wang Kai's soul power.

Finally, there is a halo effect, which slightly increases the soul power recovery speed of the soul masters around Wang Kai, which is also an unexpected surprise.

"Not bad! However, I think the power of mountains and rivers can continue to be upgraded!"

With a thought, Wang Kai continued to take out two 100,000-year soul ring sublimation stones and began to refine them.

......

Several hours passed. This time, there were nine extremely complex patterns on the third soul ring behind Wang Kai, revealing an extremely terrifying momentum. The color also changed from the original light red to the deep red, and there was a faint layer of light gold.

Yes, refining two 100,000-year soul rings again, the Mountain and River Power Soul Ring has successfully advanced to a 900,000-year soul ring, which is only one step away from the legendary million years.

After further promotion, the effect of the power of mountains and rivers is also enhanced again. It only takes one second to fully restore all of Wang Kai's soul power. In other words, Wang Kai's soul power has basically reached a point where it can never be consumed. Even if it is completely consumed, it can be filled in instantly.

At the same time, after upgrading the power of mountains and rivers from 300,000 soul rings to 900,000-year soul rings, Wang Kai's physical attributes were also greatly enhanced.
