Chapter 396: Mental Power Soars (Part 1)

After becoming familiar with it, Ye Feng's efficiency in refining spirits became faster and faster.

Basically, in the end, it only takes 3 seconds to refine the spiritual sea of ​​a fourth-order mutant spider, 6 seconds for a fifth-order one, and 10 seconds for a sixth-order one.

Of course, in the end, Ye Feng basically only chooses sixth-order mutant creatures for refining spirits. The reason for this is of course because of the harvest.

For example, if the spiritual sea of ​​a fourth-order mutant creature is refined, the spiritual source obtained is 1, then refining a fifth-order mutant spider is 10, and refining a sixth-order mutant spider is 100.

And a sixth-order mutant spider provides Ye Feng with 100 times the spiritual source of a fourth-order mutant spider, but the time difference between them is only a little more than three times.

If he wants to maximize efficiency, Ye Feng naturally knows how to choose.

But even if Ye Feng only refines sixth-order mutant spiders, these 500 sixth-order mutant spiders took a full 83 minutes.

It took such a long time, and the harvest was also great.

When the last mutant spider was also refined, the size of the Golden Crow expanded by nearly one third compared to before.

Of course, this is only the first step. When the Golden Crow returns to the Sea of ​​Spirit, Ye Feng still needs to use the Golden Crow Refining Method to integrate the spiritual essence in the Golden Crow into his spiritual sea, which is considered to have completed a round of real refining.

This is equivalent to using the Golden Crow for a transfer, so the spiritual essence he obtained can fit with himself.

Ye Feng can clearly feel that the sea of ​​spirit is constantly expanding, and his mental power has also begun to increase rapidly.

After 5 minutes, this round of improvement stopped. Ye Feng carefully sensed that after only one round, his mental strength increased by 5%.

"It really deserves to be a mental secret technique that even the Heavenly Court has to pay attention to. The effect of this improvement is immediate! At this rate, my mental strength can be increased by 100% in at most one day."

Ye Feng couldn't wait to start searching for the place where the mutant creatures gathered.

Of course, before that, he would open the tactical computer, check each team, and send back a battle report every half an hour.

After confirming that nothing happened, Ye Feng immediately turned his attention to the valley 5 kilometers away, where there was also a huge mutant spider nest.

And there were more sixth-order mutant spiders, about 700.

As soon as Ye Feng took a step, his figure appeared above the valley with a wave of space.

Just when Ye Feng wanted to take action, his eyes were cast on a group of mutant wolves wandering on the edge of the valley.

This group of mutant wolves obviously wanted to attack this valley, or to be more precise, the prey on the spider webs in the valley.

Of course, Ye Feng had no time to care about what these mutant wolves wanted to do. His eyes fell on the three sixth-order mutant wolves in the lead.

"Speaking of which, I haven't tried to refine the spirits of these sixth-order mutant animals!" Ye Feng whispered to himself, took another step, and appeared in front of the mutant wolf pack.

These mutant wolves' intuition about danger is far superior to those mutant animals. The next moment they saw Ye Feng, they did not attack, but instead tucked their tails and began to run away.

But how could they escape from Ye Feng? In the blink of an eye, all the mutant wolves fell into an illusion.

Then the Golden Crow appeared again and crashed into the spiritual sea of ​​a sixth-level mutant wolf.

Ye Feng instantly realized that the spiritual sea of ​​these mutant animals was much stronger than that of mutant insects, at least twice as strong.

But for Ye Feng, that was all. As the spiritual flames rose from the Golden Crow, the entire spiritual sea began to collapse rapidly.

This time, Ye Feng spent about 20 seconds to refine the spiritual essence in the spiritual sea of ​​this mutant wolf and integrate it into the Golden Crow.

"Damn, what a loss!" Ye Feng couldn't help muttering.

Of course, the reason why he said this was not because the spiritual essence obtained from the mutant wolf was too little, but on the contrary, it was more than he expected, and it was 5 times that of the mutant spider.

Spending twice as much time can earn five times as much income. In other words, refining these mutant animals can earn 2.5 times more than refining mutant insects.

The reason why he said he lost money was that he had just wasted more than an hour on those mutant spiders.

But now that he found out, it was not too late.

He quickly refined three sixth-level mutant wild wolves, and then directly let Jinwu release the spiritual fire to kill all the remaining mutant wild wolves.

"Next, it's time to look for those mutant animals."

Ye Feng's mental power began to sweep the area on a large scale.

With his current mental power strength, the farthest exploration distance can reach hundreds of kilometers. As he closed his eyes to explore, soon one by one, the sixth-level peak mutant animals were searched out by his mental power.

Of course, Ye Feng did not leave immediately, but he solved the more than 700 sixth-level mutant spiders in the valley, and then left.

In a blink of an eye, half an hour passed.

Although Ye Feng only refined 90 mutant animals in this half hour, his mental power has increased by 5%, and the total increase has reached 10%.

Such an improvement speed is naturally very fast, but the smile on Ye Feng's face disappeared.

"I really didn't expect that I would reach the limit so soon." Ye Feng whispered to himself.

Of course, the limit he mentioned is not that the sea of ​​​​spirituality cannot continue to expand, but a limit that he can accommodate in a short period of time.

Although Ye Feng absorbed the spiritual origin and it has been transformed by the Golden Crow, it is still an external thing after all, and it needs to complete the last step of assimilation before it can completely become his own.

In fact, this assimilation has been going on all the time. As time goes by, the spiritual origin absorbed back will naturally become his.

But the problem is that Ye Feng's efficiency in absorbing the spiritual origin is too high. In just less than two hours, his spiritual power has skyrocketed by 10%, which caused the speed of assimilation to not keep up.

And 10% is an upper limit. If Ye Feng continues to madly improve his spiritual power, then there may be problems.

So all he has to do now is to wait.

Ye Feng felt it silently. It would only take half a day for his sea of ​​​​spirituality to completely assimilate the newly absorbed spiritual essences.
