C66 I Was Almost Squeezed Dry by These 15 Kilometers

Su Mu once again invested 2000 evolution points into upgrading the Fog to LV2. In the end, the skill turned gray and was unable to be upgraded.

Fog (LV28000/3000): Consumption of a certain amount of spiritual energy to create a mist 15 km in diameter.

"Looks like I can only upgrade this skill to LV2. However, I can still use it at a distance of 15 kilometers."

Most of the spiritual energy in Su Mu's body had been consumed and his soul had become sluggish. The price was that the fog had quickly spread from 1 km to 15 km.

"Luckily, the system set a restriction, preventing me from evolving to LV3." Su Mu felt a lingering fear as he felt the remaining meager spiritual energy in his body.

Su Mu didn't expect the Mist to consume so much spiritual energy after leveling up to LV2. If he forcefully activated it after LV3, then with this little amount of spiritual energy, he would be unable to supply at all. At that time, it might endanger his source energy and even his life.

This restriction by the system was more like a form of protection for Su Mu.

Su Mu swallowed the spiritual energy for a while and finally recovered from the dry feeling. He glanced at his remaining skills and found that the 8,000 evolution points were just enough to upgrade a skill. Without any hesitation, he upgraded the mutated tree to LV2.

After Su Mu upgraded this skill to LV2, his torso underwent an astonishing change.

The tree trunk rapidly grew, reaching a height of 100 meters!

This height was still far from the towering skyscrapers of his previous world, but it could already be considered the tallest building in those small cities.

Right now, that mountain-like wild mountain pig was only a strong little pig in front of Su Mu.

The kind that could be casually crushed to death.

Compared to the tree trunk, the change in Su Mu's underground roots was more shocking.

It was only after breaking through from a hundred meters to a kilometer that the crazy growth finally stopped.

In addition to the changes in height and depth, Su Mu's strength and hardness also received varying degrees of increment.

The current him was stronger, bigger, stronger!

The pleasant thing was, his rate of absorbing spiritual energy and turning it into an evolution point had increased from 0.1 to 0.2 per minute!

In terms of numbers, it only increased by 0.1, but with the accumulation of one week, Su Mu could get 2016 evolution points!

This kind of profit would be faster than killing a creature of the same level.

Moreover, he had a faint feeling in his heart that an uncontrolled slaughter was not a good thing for him.

This further strengthened Su Mu's mindset: Killing is the best way to train, while training is the best way to do it.

Su Mu sank all of his thoughts into the bottom of his heart, opened up the system and started appreciating it.

Su Mu looked at the big duck egg at the back of the evolution spot and sighed helplessly. "Sure enough, no matter what era it is, money will never be enough."

However, Su Mu didn't feel much regret. Evolving something like this, as long as he was alive, he would be able to obtain it.

Changing them into his own strength was the clear choice.

Everything in this world was fake, and only power was real.
