It seems that Kerry's analysis still makes sense, if the demon god really exists, he will not treat himself so "gently". With the strength of the demon god, he can take the absolute initiative as soon as he comes up.

Gu Tiancheng thought for a while and had a clear understanding of the strength of the two sides. Although there is a lot of negative energy outside, no matter how much it is, it is all of a demon god. The Demon Gathering Banner can be a three-headed dog of hell that has been banned, and it can completely contain the negative energy from the outside.

Thinking of countermeasures, Gu Tiancheng reappeared, although he didn't know how to urge the Demon Gathering Banner to absorb the energy outside. But Gu Tiancheng had a stupid way to directly open the channel for the internal and external contact of the Demon Gathering Banner.

"Enjoy the feast!" Gu Tiancheng shouted.

That is, in the blink of an eye, within a few hundred meters around Gu Tiancheng, the black cloud-like negative energy was swept away.

The other negative energies were very knowledgeable, and they also hid far away, not daring to get too close to Gu Tiancheng.

At this point, Gu Tiancheng fully believed: the demon god should have been completely absorbed by Hai Qingzhu, and the negative energy in it was the surplus that Hai Qingzhu could not absorb or want.

These negative energies have been here for a long time, and over time they have developed their own consciousness. In the end, it is the energy of the demon god, and the newly generated little demon god naturally inherits the residual consciousness of the former demon god.

But the little demon god has an empty shelf, but he doesn't have much strength, and he doesn't know how to use his own energy to fight.

In the face of such an opponent, Gu Tiancheng can completely deal with it.

Stretching his body, Gu Tiancheng relied on the Demon Gathering Banner to scatter wildly, as more and more negative energy was absorbed by the Demon Gathering Banner, the body of the little demon god gradually couldn't be hidden, and it was slowly revealed.

The little demon god has always lived here, and he has never seen such a vicious enemy, and he is so frightened that he is crying like a baby.

Gu Tiancheng couldn't bear to see it, but the monsters in the Demon Gathering Banner didn't care about those, and sucked the little demon god into the Demon Gathering Banner at once.

Gu Tiancheng was deeply moved, and hurriedly followed into the Demon Gathering Banner, pleading with those powerful monsters, asking them to raise their noble hands and let the little demon god go.

The little demon god was already quite spiritual at this time, although he was the same as Gu Tiancheng's energy, and he was the same kind as the few people in front of him, but the little demon god could tell that Gu Tiancheng was here to save him, and those people were going to eat him. So he hid behind Gu Tiancheng and didn't dare to show his head.

The net worth of those people depends on Gu Tiancheng, of course, they don't dare to offend Gu Tiancheng. Gu Tiancheng wanted to protect the little demon god, of course they agreed.

Anyway, for them, as long as there is a sufficient source of negative energy, multiple little demon gods are equivalent to multiple playmates, so why not.

To save the life of the little demon god, Gu Tiancheng did not stay in the demon banner for long, and came out soon, at this time, the space outside was already empty, and there was not a trace of negative energy, and he was sucked clean by the demon flag.

Not even a little aura. Cultivating in this area, how can you do it without aura?

Gu Tiancheng immediately started and set up several spirit gathering arrays inside. The Spirit Gathering Array is also a high-level and low-level distinction. In addition to the level of the formation, the choice of the base material used also affects the level of the Spirit Gathering Array.

Hai Qingzhu itself is a high-grade spirit gathering array base material, Gu Tiancheng only needs to depict a high-level spirit gathering array on it, and he can form a large spirit gathering array, and its absorption of spiritual power can even form a spiritual energy vortex effect around it!

Of course, having aura is not enough, the most important thing is how to master the time setting of the internal space of Haiqingzhu. This, Gu Tiancheng is like a tiger gnawing the sky, and he has a feeling that he has nowhere to put his mouth.

Fortunately, Kerry reminded Gu Tiancheng in time that Gu Tiancheng did not need to find this in particular, because the body of Haiqingzhu is a treasure warehouse deep under the sea, and its internal space settings are almost unchanged.

It's just that this effect can't be changed according to people's wishes, and you can only enjoy the original setting of Haiqingzhu.

Gu Tian became the original time setting of Hai Qingzhu, specially went in and out more than a dozen times, carefully recorded the difference between inside and outside time, and finally found that the speed of outside time was ten times the speed of time inside!

That is, ten hours outside, but only one hour inside. Although it is too far from the time control level of "one day in the sky and one year on the earth" in Gu Tiancheng's heart, the ten-fold gap is enough, and he can't ask for more.

The negative energy in Hai Qingzhu has been completely sucked away by the Demon Gathering Banner, and it will not pose any threat to Gu Tiancheng. Gu Tiancheng took the sea green pearl in his hand and began to seriously consider how to use it.

Just using Haiqingzhu as a feng shui treasure for rapid cultivation, Gu Tiancheng always felt that it was a bit too wasteful. After all, Hai Qingzhu's combat effectiveness is not bad, and such a powerful combat magic weapon is only used for cultivation in his own hands, Gu Tiancheng feels a little lost no matter how he thinks about it.

However, most of Hai Qingzhu's original circle settings were involuted, in order to seal the negative energy in it from leaking. Now that the negative energy is gone, the natural corresponding magic circle will lose its effect, which is equivalent to freeing up a huge amount of magic circle space, which is the space that Gu Tiancheng can play freely.

If it were left in the past, Gu Tiancheng would definitely be interested in practicing his latest research results on Hai Qingzhu to maximize Hai Qingzhu's combat effectiveness.

But now Gu Tiancheng knows that there is still a big gap between the formation system he understands and the ancient formation. Even if he could move the strongest formation he understood to Hai Qingzhu, Hai Qingzhu was still not the opponent of the ancient artifact.

In Gu Tiancheng's opinion, if you can't fight against the artifact, it's better not to get it. However, the process of dismantling the formation just now was a rare learning process for Gu Tiancheng. At least a little experience in the formation and operation of solid-state formations.

But Gu Tiancheng's experience can't be used to show off to Kerry at all. So this time, Gu Tiancheng humbly asked Kai Rui for advice, hoping that Kai Rui could help him design a complete set of formations, and Gu Tiancheng would eat ready-made, so he didn't have to waste his brain cells.

Kerry was very dissatisfied with Gu Tiancheng's this, thinking that he did not seek improvement. Because in Kerry's view, the human brain development rate is too small, Gu Tianchengkong has such a powerful brain system, but he only knows how to be lazy all day long, and only knows how to play with a few girls to satisfy psychological pleasure, but he doesn't know how to develop his own brain.

According to Kerry's calculations, as long as Gu Tiancheng was willing to spend effort to increase even one percent of the brain development rate, it would not be a problem to understand those ancient formations.

This is the difference between a human and a computer, just as Gu Tiancheng can't understand Kerry's strong computing power, Kerry also can't understand that the human brain development rate is so low.

However, Kerry's complaint made Gu Tiancheng have a new idea, since spiritual power can greatly improve people's physical functions, and even make people have super energy, will there be rich gains from using spiritual power to develop the brain?
