The first step of the refining of the Tianyan instrument was stuck, which made Zhang Zhiping quite annoyed in his heart, materials are the basis of refining, any alchemy is based on spiritual materials, a material can be derived from a variety of different refining methods, but no matter how many refining methods, there is no material and no rice cooking.

However, Zhang Zhiping naturally would not give up, he began to flip through various spiritual materials to see if he could find a replacement among the countless materials recorded on the island, and at the same time, he also used the eyes of the celestial people to carefully observe the materials on the celestial instrument in front of him to see if he could deduce the refining method from them.

It's just that the uniqueness of the Yuan Spirit Crystal is the basis for it to become the Heavenly Evolution Instrument, how can it be so easy to find a replacement, and if you want to deduce the refining method from the finished product, it is even more fantastical, no matter how he detects, he finds that these Yuan Spirit Crystals seem to be compressed and condensed by the purest spiritual energy, and the mystery lies in its structure.

However, no matter how he tried, it was difficult for him to control its stable existence, even if he forcibly built this structure with the help of strong control, it would not be able to restrain the aura and make it firmly formed, as long as he let go of the control a little, it would turn into an aura again.

I have to say that the technology of Tiangong Island is not so easy to crack, even Zhang Zhiping can't think of cracking it in a short time without any foundation, and to add insult to injury, he found that the speed of his invasion of the island ban has been greatly slowed down.

The prohibition on the island is not vegetarian, the various defense systems, confidentiality systems, etc. are interlocking, closely connected, and the layers are like one, and it takes a lot of energy to crack each layer of prohibition, and the prohibition on the island is not only tens of thousands of layers?

For a while, Zhang Zhiping's plans on the island fell into a bottleneck, and he suddenly gave Zhang Zhiping, who has always been a little proud, a slap in the face, after all, it is a place where the essence of immortal cultivators has been concentrated for tens of thousands of years, even if he has the body of heaven and man, it is difficult to override himself over countless amazing and beautiful people.

Therefore, Zhang Zhiping could only reluctantly suspend the plan, put his mind into the phantom instrument, and began to study the public information published on the island, which is regarded as the island's welfare for various technicians, and he can browse with all his heart without worrying about leaving any traces.

Of course, don't expect any advanced principles in it, except for the foundation construction, which is very commendable, there is nothing else, if you can fully understand it thoroughly, it will lay a solid foundation for yourself, but if you want to further study the method or derive the development of the secret method, you need the corresponding authority and a lot of merit in exchange.

And Zhang Zhiping, since breaking through the Jindan period, the forbidden manufacturing attainment has advanced by leaps and bounds again, and he needs these foundations to constantly enrich himself, so he soon entered the study of the island's materials, sharpening his knife and cutting wood, since his current level of prohibition is difficult to support him to continue to invade Tiangong Island, then he will raise it to the limit and then advance his plan.

Time is like an arrow, the sun and the moon are like a shuttle, five years have passed in the blink of an eye, Ishihara began to set up a blood spirit ban for a brand new white bone tower, and the black soul Taoist on the side has a very tacit understanding with him It is easy to sacrifice to the spiritual altar, and in every move, it only takes less than two months for them to complete the transformation and refining of a resentful bone tower, if this time is calculated, they can barely complete the task after ten years.

Therefore, in the past five years, Ishihara has only been given a few breaks to recuperate, and every time he returns to the cave, he has to use his authority to constantly open and exchange a large number of forbidden materials in the phantom instrument, so that Zhang Zhiping can conduct further research.

Finally, although he still did not raise his authority to level seven or above, he found a way to clear the traces, and he no longer needed Ishihara, and his ontological divine thoughts could directly travel in the Celestial Evolution Instrument, reading a large amount of information silently, which greatly accelerated the speed of his forbidden cultivation cultivation.

It's a pity that this kind of quiet reading can only be established under authority, and it is difficult to copy and deduce, and he must rely on his own forcible memory, and he can't even compare to the efficiency of reading jade slips, so in the past five years, he has not found a substitute for Yuan Lingjing or a refining method, which makes it difficult to implement the plan.

However, from this, he also has a way to speed up his own erosion of the prohibition, that is, to use the celestial instrument to expand his deduction ability and speed, in terms of pure calculation and deduction, it is always difficult for the divine soul to burst out of all its potential, after all, it is not good if it accidentally causes the divine soul to be damaged, so he must give his powerful computing power a carrier and auxiliary thing, in order to analyze the prohibition on the island in the shortest possible time and steal the authority on the island.

Therefore, in the end, the crux of the problem returned to the celestial instrument, and Ishihara kept thinking about the method of solving the material of the celestial instrument, and finally one day, he had a flash of inspiration and had an idea.

The foundation of the celestial instrument is the heavenly performance ban, and the heavenly performance ban is a powerful prohibition that imitates the operation of heaven and earth, so it has a strong carrying and deduction power, but the complicated heavenly performance ban cannot exist out of thin air, and it still needs the Yuan Lingjing to carry it down and form the basic celestial instrument.

Therefore, the foundation of the Celestial Evolution Instrument lies in the Yuan Spirit Crystal that carries the Heavenly Evolution Forbidden, and on the Yuan Spirit Crystal, he has been unable to make a breakthrough for a long time, but he finds that he seems to have a better foundation, that is, the Heaven and Man Space.

The space of heaven and man itself is a perfect small world, although it is only a hundred meters in a circle, but it can carry matter, give birth to life, and has extremely huge potential, so since its formation, Zhang Zhiping has been thinking about how to use it, the simplest of which is to plant various elixirs in it, because he found that the space of heaven and man is extremely beneficial to the growth of elixir, and the growth rate of elixir far exceeds that of the outside world.

It's a pity that this growth rate is still too slow for him, because after breaking through the Jindan period, the elixir he needs generally starts at a thousand years, even if the growth rate is twice as fast, it will take hundreds of years to take shape, so if he wants to cultivate the elixir from scratch, he can't meet his needs in a short time, even if he deliberately cultivates some elixirs that are about to mature, it is meaningless for him, at most it has some effect in transplantation, and if he encounters any cherished elixir, he can go directly to the heavenly space.

But just these effects, naturally far from Zhang Zhiping's expectations, he tried to take the initiative to control the Celestial and Human Space to double, but as soon as he ran it, his body felt a huge pressure, and he could not bear the pressure brought about by accelerating the operation of heaven and earth, so in desperation, he could only temporarily let the Celestial and Human Space stay in his Purple Mansion, and wait until he had time in the future to think about how to develop it deeply.

And today, he suddenly had an idea, the Heavenly Evolution Forbidden is just imitating the operation of heaven and earth, so how can a Yuan Spirit Crystal that carries the Heavenly Evolution Forbidden be more powerful than a complete heaven and earth, if he is based on the heavenly and human space, can he develop an unprecedented Heavenly Evolution Instrument?
