Gu Tiancheng is a person who has invented new combat techniques, so he naturally understands most of the logical compositions, and if he puts them in Kai Rui's place, even if there is a small amount of logical composition that is not clear, it does not prevent Kai Rui from deducing the logical composition and element composition of the entire combat technique based on this.

Moreover, only if he could be deduced from beginning to end by Kai Rui the battle skills of logical composition and elemental composition, Gu Tiancheng dared to cultivate boldly with confidence.

After all, it was left by Allen, and Gu Tiancheng had to keep an eye on it.

As for the Mayan Divine Bow part in the back, Gu Tiancheng chose to give up very cautiously. The Mayan Divine Bow is Allen's thing, and if Allen wants to do his hands and feet in combat skills, it is most likely the Mayan Divine Bow part.

While it's tempting to be able to use the Mayan Bow freely, it's too risky. Because of the use of the Mayan Divine Bow, Gu Tiancheng couldn't understand it, so he could only write it in the book and do it himself, which was too easy to get hit.

Anyway, the Mayan Divine Bow is in his hand, and he can use the Mayan Arrow once a day, which is enough, and it should be used as a life-saving skill at a critical time.

In addition to these, there are also some materials written by Allen in Maya, which Gu Tiancheng couldn't understand, so he had to give up.

I have to say that Eren is really poor, except for usage and combat skills, there are almost no good things left. But it's no wonder that Allen, he himself was sealed here as a remnant soul, and even if there were many good things, he could only be snatched away by the gods who sealed him at that time.

While everyone else was cultivating, Gu Tiancheng took out his bloodthirsty demon bow, preparing to further demonize and improve his attack power.

The Bloodthirsty Demon Bow is made from the rib bones of the Bloodthirsty Lion and the Kodomon, which is certainly a top-notch weapon in the world, but compared to those artifacts that have been handed down, it is not half a star.

Although Gu Tiancheng can rest the first part of his bow and arrow skills, he can form a bow and arrow with spiritual energy, and his power will be greatly increased. But the Bloodthirsty Demon Bow is still valuable, after all, it doesn't consume much spiritual power when used, and it can be used completely in ordinary battles.

And the psionic bow condensed by spiritual energy is a little embarrassing, it is too luxurious to use in ordinary times, and it is not the opponent of those artifacts at critical times, and there is really no time when they have to appear.

The bloodthirsty magic bow needs to be changed, of course, it is to improve the strength and toughness of the bow body as much as possible, and the material determines that the upper limit of the magic bow is so high, but Gu Tiancheng can use the spiritual fire to calcinate it.

This is Gu Tiancheng's newly acquired skill from cultivating the complete Allen Gong Method: using his own cultivation to give birth to a spiritual fire that is completely controlled by himself, so that he can accurately calcinate some materials at will to further improve the quality of all aspects of the material, and there is a small probability that he can obtain higher-level materials.

Gu Tiancheng's bloodthirsty demon bow was already a finished product, and Gu Tiancheng only needed to calcine it in a few key parts to improve its attribute quality.

This doesn't have much effect on the Magic Bow, and the main purpose of this is to divide the originally complete Magic Bow into assembleable parts.

Not all parts of the magic bow need high strength and high toughness, for these key vulnerable parts, Gu Tiancheng can customize a batch of accessories of the same standard, if there is damage during use, it can be replaced at any time.

In this way, the Bloodthirsty Demon Bow in Gu Tiancheng's hand was not an ordinary psionic weapon, but an industrialized product!

The benefits of this are obvious, Gu Tiancheng can unleash all the potential of the Bloodthirsty Demon Bow in battle, and he doesn't have to worry about the Bloodthirsty Demon Bow being damaged because of this.

Moreover, Gu Tiancheng can also add parts with better attributes to the bloodthirsty demon bow in time, so as to complete the magic transformation of the bloodthirsty demon bow and further improve his strength.

After all, it is from the earth of industrialized civilization, and the concept of industrialized large-scale and standardized production is deeply rooted in Gu Tiancheng, and as long as possible, Gu Tiancheng will practice this concept without hesitation.

According to this concept, Gu Tiancheng strengthened the three key positions according to the working principle of the magic bow, and separated them from the overall bow body, and then made an ingenious tenon joint structure, which looked perfect after being reinstalled.

Gu Tiancheng took it in his hand and tried it, feeling very satisfied, so he put down the bloodthirsty demon bow. Start researching the Seal Circle here.

This is the treasure house of the sealing circle, and Gu Tiancheng has often come in to study before. With Gu Tiancheng's in-depth study of the formation, the knowledge of the sealing array that he can learn from it has also become more and more in-depth.

Although some of the magic circle logic compositions are obviously beyond the ability to appear in the Shining Continent, such as using a large number of spirit yuan stones to refine a higher layer of energy, the Shining Continent is unable to do it now. After all, the Lingyuan Mine has almost been depleted, and occasionally a little Lingyuan Stone is a treasure, and it is impossible to be extravagant enough to take a large amount of Lingyuan Stone to refine a higher level of energy.

But Gu Tiancheng can still learn something from it. At least, Gu Tiancheng realized that the spirit element energy was not the strongest, and there were stronger energy units up there.

Moreover, the use of spiritual energy can also be glimpsed in it. In particular, the separation and fusion of yin and yang psionic attributes is the psionic knowledge that Gu Tiancheng diligently pursues.

With the deepening of his study and understanding of the sealing circle, Gu Tiancheng gradually realized that the sealing circle was not the space of the Mayan Divine Bow. This space should be a space that those ancient gods forcibly carved out inside the Mayan Divine Bow, and then forcibly carved a sealing circle to seal Allen's remnant soul inside.

A space was split into the interior out of thin air, which should certainly have an effect on the Mayan Divine Bow. If this sealed space can be restored, I am afraid that the Mayan Divine Bow will be able to return to its original power.

But for this, I'm afraid only Alan has this obsession. For Gu Tiancheng, the current Mayan Divine Bow is strong enough, and there is no need to make any improvements.

Besides, these refining materials, which were very scarce in ancient times, are not available at all now, and it is impossible to do them.

Thinking of this, Gu Tiancheng's heart moved, the Mayan Divine Bow is Allen's, and the person who can urge the Mayan Divine Bow the most should be Allen.

Just now, he hid in the sealing space inside the Mayan Divine Bow, and he could also urge the Mayan Divine Bow to complete a shot at that gray old man. It is said that Eren can also control the Mayan bow in this way.

But the fact is that Eren can't control the Mayan Divine Bow! Of course, this is because Eren was sealed, and it is also possible that the existence of this sealing circle has destroyed the connection between Eren and the Mayan Divine Bow, so that Eren can no longer have the Mayan Divine Bow!

Gu Tiancheng continued to think along this line of thought, and the more he thought about it, the more terrifying he felt, so he forcibly stopped himself from continuing to expand.

This Mayan god bow is full of games between Eren and the ancient gods, and if he inadvertently inserts a foot in it, if he doesn't get it right, he will become a victim of the struggle between the two.
