Lei Wei is really rich, countless superb spars, a huge dream ring, and "Bi Zhu Dan" for healing. And now all this is Qin Yu's.

However, Qin Yu felt that the greatest wealth that Lei Wei had given him was those cultivation cheats. Each of these cheats is special and powerful.

There are about alchemy, about refining, about formations, as well as the magic book "Nameless", the demon book "Doppelganger" and so on.

No matter which one is taken out, it will set off a storm in the cultivation realm.

Among them, what excites Qin Yu the most is not the magic book "No Name", but the demon book "Doppelganger".

The demon book "Clone" is really powerful, it allows cultivators to choose the clone they want independently. For example, if a demon clan wants a five-clawed golden dragon as a clone, they can take the blood of a five-clawed golden dragon to give birth to a five-clawed golden dragon clone.

Of course, the restrictions of the demon book "Clone" are also very strong.

One is that only creatures with two or more souls can cultivate. And those with more than two souls can only be the demon clan. Like the three-headed dog of hell, hydra and so on. It is impossible for a human being to have two souls. Therefore, the demon book "Doppelganger" is the cultivation method of the demon clan.

Of course, Qin Yu is a special case, and the reason why he has two souls is related to his main soul characteristics.

However, Qin Yu can indeed cultivate "Clone". Because he does have two souls.

The second restriction of the demon book "Clone" is that the clone cultivated has no meridians, and there is no dantian to cultivate the body cultivation method. And "Doppelganger" has a supporting body cultivation method "Refining Body Decision".

That's right, it's the book "Body Refining Decision" that Xiang Ying got!

Of course, Qin Yu didn't know that Xiang Ying had obtained the "Body Refining Decision", but he had been thinking about how to use Xiang Ying.

First of all, he can't kill Xiang Ying, what if he kills Xiang Ying, what if Xiang Ying gets half a tear of life back on him? Isn't his plan in vain?

Secondly, Qin Yu may control Xiang Ying. Because he wanted Xiang Ying and Jiang Li to come into contact with Jiang Lan. What if Jiang Lan knew about his control of Xiang Ying? Isn't that self-defeating?

But Qin Yu wanted to guide Xiang Ying and Jiang Li to contact. That can only start with the people around him. And this person Xiang Ying must be absolutely trusted. And today's demon book "Doppelganger" just solves Qin Yu's problem. That's why Qin Yu was excited.

Of course, whether it is "No Name", "Doppelganger", or "Star Change", it is not something that can be cultivated now.

These required Qin Yu to survive the forty-nine heavenly tribulations before he could cultivate. Therefore, Qin Yu's task now is to get through the Forty-Nine Heavenly Tribulation as soon as possible.

"It's time to start cultivating, if you want to go back through the flood wilderness alive, it is impossible to succeed without the 'Nebula Stage'. Moreover, I must rush back before my father survives. Qin Yu immediately left the room and began to cultivate seriously.

The Forty-Nine Heavenly Tribulations can only sense the Forty-Nine Heavenly Tribulations when they have attained the Innate Great Perfection and have a perfect state of mind. Just like Lian Yan became an innate Great Perfection for more than ten years before he sensed the Forty-Nine Heavenly Tribulations after Yi Qingyu's death, it was because his thoughts were not clear and his state of mind was not perfect enough.

However, the reason why Qin Yu didn't sense the Heavenly Tribulation was not because the Heavenly Dao didn't have enough comprehension. After all, his soul realm was already in the Jindan stage. And the reason why he didn't sense the Forty-Nine Heavenly Tribulations was because he hadn't yet reached the Innate Great Perfection.

Although Qin Yu's cultivation of the "Three Diagrams of Tongtian" has already reached the realm of three-color armor, and 108 qi pillars surround the surface of his body at the same time, it does not mean that Qin Yu is the Innate Great Perfection, after all, his cultivation time is still short, and there is still a short distance from the real Innate Great Perfection.

In a flash, it was half a moon, and for half a month, Qin Yu had been cultivating Tongtian Xuangong.

In the middle of a bend of the blue water outside Lei Shanju, Qin Yu closed his eyes and stood quietly in the middle of the lake, his feet floating motionless on the surface of the lake. At the same time, there were 108 qi pillars on the surface of Qin Yu's body around his body at the same time.

In the past, it was necessary to follow the actions of the "Three Pictures of Tongtian" to form silver, gold, and purple air columns. However, in the past few days, Qin Yu has made a breakthrough by cultivating and comprehending the Heavenly Dao, and even if he does not move, he can still appear at the same time with three-color armor. Obviously, it was only he who had truly attained the Innate Great Perfection.

"Boom!"

Qin Yu's heart shook suddenly, and the whole person couldn't maintain the realm just now, and fell directly into the water. Qin Yu suddenly came to his senses, slapped the water with one hand, and the whole person stood on the water again, Qin Yu was full of excitement at this moment.

"Five months, five months later, it's four or nine heavenly tribulations, okay, it's really good." Qin Yu's eyes were full of excitement, just now a broad energy directly penetrated into the depths of Qin Yu's mind, and then Qin Yu understood when he had crossed the tribulation, this feeling was really mysterious.

At this moment, an eagle roared in the sky, and the black eagle swooped down directly, during these days, Xiao Hei often hunted the prey of the surrounding beasts, and the general innate beasts were not Xiao Hei's opponents at all.

Now that he had sensed the Heavenly Tribulation, Qin Yu was relieved. As for whether he could survive the Forty-Nine Heavenly Tribulation safely, Qin Yu had no doubts at all.

Although he doesn't have a Yan Chi Fist and a Yan Chi Sword now, he has a middle dantian. Qin Yu, who has a middle dantian, has more than doubled his strength. He was naturally very confident in the catastrophe.

Qin Yu, who was idle, began to study alchemy, refining weapons, and formations.

Although the three things of alchemy, refining tools, and formations that Qin Yu couldn't implement now, it didn't prevent him from studying them.

The first requirement for alchemy is to be familiar with the characteristics of various herbs, and to know which herbs can be matched and which herbs are rejected according to the different characteristics of the herbs. In short, alchemy is a very broad science. However, Qin Yu was very interested in alchemy.

Originally, he was very interested in medical skills, and he had mastered the herbs and pharmacology of the mortal world to the extreme. Nowadays, contact with alchemy is naturally handy.

Moreover, Qin Yu's main soul is very powerful, as long as he has seen anything once, he will never forget it. Therefore, those herbs and pharmacology, as long as he memorizes them once, can remember them in his mind exactly in the slightest.

However, Qin Yu also understood that the medicinal properties and pharmacology of the herbs mentioned in the books still need to be known through personal experiments. After all, books are not something that can be absolutely trusted.

Today's Qin Yu can naturally only memorize the medicinal properties and pharmacology of those herbs, and he is not qualified to experiment now.

Similarly, Qin Yu was also very interested in refining weapons.

In the original book "Star Change", there are still many descriptions of refining tools. It also expounds the basic principles of refining.

Refining the embryo, quenching, enlightening. This is the three-step method of refining.

If refining and quenching is a test of the degree of knowledge of the material, as well as personal experience. Then the test of the spirit is the study of the formation. Although this is the method of refining weapons in the divine realm, it also applies to the lower realm.

In the Divine Realm, Qin Yu could use ordinary materials to refine a Heavenly Artifact, but couldn't he use a medium-grade spar to refine a top-grade spiritual weapon or even a top-grade spiritual weapon now?

Qin Yu thought, this is okay. The more proficient he is at the formation, the more powerful weapons he can craft from lower-level materials.

Therefore, the root of refining weapons is still the formation. Because only the formation can give the soul to the weapon.
