Zhou Feng had made a lot of preparations earlier, so the refinement process of Ice Heart Gu was smooth; there might be a trace of luck involved.
'This is Ice Heart Gu?'
Zhou Feng looked at this chubby silkworm in front of him, his eyes filled with curiosity.
To be honest, other than the Demon-Devouring Gu, he had not seen many Gus.
This Ice Heart Gu was like an infant silkworm, its entire body was crystal clear, and it did not even have eyes.
Its transparent body had a red line.
Moreover, this Ice Heart Gu did not move at all. It was completely different from the active and violent Pure Blood Gu.
He carefully placed the Ice Heart Gu in his palm and slowly circulated his soul power to lure the Ice Heart Gu.
During this process, he could not be too impatient. He needed to lure the Ice Heart Gu slowly.
Zhou Feng also could not force the Ice Heart Gu to enter his body. Otherwise, the Ice Heart Gu might enter a dormant state.
This knowledge was recorded in Bitter Bamboo Peak's inheritance jade slip.
However, once the Ice Heart Gu chose to live inside a certain person, it would be easier to feed it.
It did not even need to be cared for. One only needed to pay some Spiritual Qi and soul power to make the Ice Heart Gu work for them.
Compared to most Gus, the Ice Heart Gu was the least troublesome.
Zhou Feng did not want to come into contact with the Gu system because it was too troublesome.
Different Gus needed different care, and he also needed to feed some spiritual items regularly. He preferred the simpler and rougher ones.
The Ice Heart Gu in Zhou Feng's palm slightly moved its chubby body.
Then its body shrunk to the size of a grain of rice, directly digging a hole in Zhou Feng's palm and entering his body through the blood vessels.
Finally, the Ice Heart Gu entered the Gu Aperture that Zhou Feng had opened before and settled down.
And this so-called Gu Aperture was a place specially opened for Gus to live in.
In the Tri-Gu Sect's system, besides the Vital Gu, all the other Gus that lived in the body had to live in the Gu Aperture.
Gu Apertures were similar to apertures in humans, and they could be opened very easily.
Moreover, they had almost no effect on the human body.
The only thing that had some effect was that this Gu Aperture could not be opened too much. Opening a large one would cause problems.
'This is…'
When the Ice Heart Gu entered the Gu Aperture, Zhou Feng could clearly feel a cool aura spreading throughout his body.
This cool aura directly rushed to his head.
In an instant, he was much more awake.
'This is a very refreshing feeling.'
It was as if the world in front of him had been cleansed, and his eyes brightened.
The problem that troubled Zhou Feng was instantly discarded.
'This is too great!'
Zhou Feng felt that he had gotten rid of the pressure of 10,000 jin.
In contrast, his soul power was in a state of consumption.
Although the consumption was not much, it was still a huge burden.
Gus were like external aids the more one looked at them. As long as he used them well, they would be able to bring out unexpected effects.
He did not need to worry about the Demon-Devouring Technique's side effects now.
Next was tomorrow's battle.
'Should I forcefully draw a passive skill?'
Zhou Feng still felt a lot of pressure regarding tomorrow's battle.
At present, he felt that his strength had already reached a limit.
Grade-1 of the Soul Altar realm was already the limit. Breaking through to the Purple Mansion realm in a short period was an impossible task.
As for battle arts, weapons, and other aspects, there was almost no room for improvement.
The only option that could forcefully increase his strength was the skill panel.
As long as he obtained a good passive skill, his strength might rise in a straight line.
He wanted to put in use the summarized knowledge from earlier and speed up the skill panel's progress bar.
Other than a breakthrough in cultivation, he also needed to absorb a large amount of Spiritual Qi.
Storing a large amount of Spiritual Qi in his body would speed up the skill panel's progress bar.
However, this also meant that he needed to consume numerous Spirit Stones.
Previously, Zhou Feng had not noticed that he had squandered lots of Spirit Stones in his storage ring.
If he were to use them now, there might really not be any left.
The storage ring contained the savings of an entire Han Clan, yet Zhou Feng had almost completely squandered it.
'Should I keep this for New Year's? It has already come to this!'
Zhou Feng thought for another second and decided to spend all his Spirit Stones so that he could obtain another passive skill.
As such, he took all the Spirit Stones out of his storage ring and started to devour their pure Spiritual Qi crazily.
While he was devouring, he also opened his skill panel to observe the progress bar.
As expected, the progress bar was slowly increasing.
However, Zhou Feng's body could not contain so much Spiritual Qi, which caused a lot of it to be wasted. Not even the Demon-Devouring Gu could absorb it all.
In order to obtain a passive skill in advance, he wasted many Spirit Stones. He did not know if it was worth it, but he had already done it. There was no turning back now.
Soon, the Spirit Stones were completely depleted.
The progress bar on the skill panel was finally full.
He could now draw a new passive skill.
"Draw!"
"Drawing…"
It was this familiar process and this exciting moment again.
Although this scene had been repeated many times, Zhou Feng still did not feel bored at all. Instead, he was looking forward to it every time.
It was like opening a mystery box. Every time, there was a kind of anticipation.
"Extraction successful!"
Daylight Combat: You will be even more valiant when you fight under the sun!
Your Speed will increase by 10 points under the sun!
"Daylight Combat? Is it a passive skill that is limited by the field?"
Zhou Feng checked the new passive skill, and it seemed a little interesting.
This was already a little like a field card.
As long as he was under the sun, his speed would increase by 10 points.
His speed would increase by 10 points!
Although he did not know the specific quantification of these 10 points of speed, this was still a considerable increase in his combat strength.
Compared to his previous passive skill, these 10 points of speed increase should not be considered a small amount.
'Not bad!'
Although he was a little disappointed that he did not draw an even more abnormal passive skill, it was not considered bad. Compared to those useless passive skills, it was already considered pretty good.
With this passive Daylight Combat, he should be able to last longer in tomorrow's battle.
Moreover, tomorrow's battle was also a good time to collect souls. Hopefully, those true monsters wouldn't go on stage so early.
It would be best if they let him slowly muddle around for a while.. Finally, he would be able to use his passive Soul Harvesting to collect soul power continuously.
