Although Xu Yi didn't know what martial arts the Giant Spirit Sutra was, as soon as he heard this name, a kind of joy naturally surged in his heart.

He himself has the magical power of transforming a little giant, and the name of this secret technique also has a giant word, which is undoubtedly a perfect match.

"Gianling Sutra?" Yuan Ding was slightly stunned and hesitated for a moment, "Nephew Xu, logically speaking, no matter what secret method you choose, I should not interfere. However, I will introduce it to you first. It's fine to this Xuannv Sutra, but you are definitely not suitable."

Xu Yi nodded repeatedly, and said in his heart, nonsense...

"The God of War Catalogue, also known as the God of War Catalogue, is the ultimate martial arts of the Way of Power." Yuan Ding continued, "The Cicada Spirit Decision is a secret space technique. Although it is practiced now, it will definitely not stimulate the mystery of space. But if you choose this secret method, you will gain unexpected huge benefits when you advance to the heavenly position in the future."

Xu Yi nodded slightly. Although he had made up his mind early, it did not prevent him from wanting to know more.

"The Hundred Refinings of Life and Death are quite wonderful. Although they are also branches and secret techniques, they have some special connection with spiritual power. Mr. Xu, you have a strong talent for talismans. If you choose this secret technique, you may have a miraculous effect with half the effort."

Xu Yi was very moved. These secret techniques were more interesting than the other ones. I really want to master them all.

"As for the Giant Spirit Sutra, it is said that it is a secret technique left by ancient giants. It is modified by the powerful human race. Once used, it can even be transformed into a giant and destroy the world. However, this secret technique is not friendly to our human race, and the difficulty of practicing is the greatest among the five secret techniques."

After Yuan Ding finished speaking, he said seriously: "I have introduced the five secret techniques, you can choose again now."

Sister Zhang Miaoyan winked at him at the same time.

Do you still need to choose this? It must be the Hundred Refinings of Life and Death.

However, Xu Yi took a deep breath and said aloud: "Uncle Yuan? Thank you for your advice."

"You're welcome." Yuan Ding said with a smile.

He was also quite happy to be able to avoid a promising disciple.

"Disciple chooses...the Giant Spirit Sutra."

Yuan Ding's smile froze slightly, and the corners of his mouth twitched slightly? Or was it the Giant Spirit Sutra? As I said it was in vain just now.

He looked at Xu Yi deeply? A trace of doubt surged in his heart.

This kid doesn't look like an idiot, why does he have such a choice?

Zhang Xinxin's face was full of anxiety? Just as he was about to speak, Zhang Miaoyan held it down.

Yuan Ding was silent for a moment? He said, "Okay? Since you insisted, there must be your reasons, so I won't ask more. As for the same sentence, if you cannot open up the first branch within seven days, it would be equivalent to giving up this opportunity."

"Yes? My nephew understands."

Yuan Ding took Xu Yi to a secret room, found another book and said, "This is the fourth level of the Giant Spirit Sutra. You can watch it here and practice here? When will the first branch be opened and when will the seclusion be out."

Xu Yi was secretly happy? He hurriedly took it.

Yuan Ding walked to the door and said slowly: "Remember? I wish you good luck in up to seven days."

After saying that, he gently covered the door. As soon as the door was closed, the room suddenly fell into silence, and there was no sound.

This secret room was clearly built with special materials, but it was exactly what Xu Yi wanted at this time.

After opening the book, Xu Yi started reading it carefully.

Compared with ordinary people, his reading speed is naturally extremely fast, and he will never forget it after reading it once.

The books are not thick and the content is not much, but many of them are still obscure and difficult to understand. Xu Yi was muttering in his mind while thinking about it.

The secret method is indeed a secret method. The method of practice described in this Giant Spirit Sutra is to use true qi to open up eighteen branches on the main meridians in the body.

If the main meridian is compared to a big river, then these branches that are about to be opened are branches of the big river.

The more branches, the more true qi it can store. Whether it is fighting with people or rushing to level in the future, the true qi in these branches can become the trump card of cultivators.

However, it is never that easy to open up the branch.

If you are not careful, it will be the end of the meridians breaking down and the body will die.

Moreover, when each level opens up the branch, all branches are actually related to each other.

In other words, before you choose the top secret method, you must lay a solid foundation before you plan to practice the meridian opening. That is, you must first open eighteen foundations on the main meridian to leave room for meridian opening in the future, and then you can truly open the first branch.

This foundation is not a simple matter, or anything that can do hand and foot on the main meridian cannot be simple.

If you only have three or five foundations, it is actually very simple. Anyone with a fourth-level cultivator at the human level can do it. But the more foundations are reserved, the more it will become more unsatisfactory.

Eighteen foundations...

Even if a person with extraordinary talent is not sure that he can do it.

Xu Yi calmed down his mind, and the practice method in the book flashed back and forth in his mind.

After a long time, he sat cross-legged, closed his eyes and calmed his breath, and the true energy in his body began to flow.

The true qi flows in the body, unobstructed all the way, without any hindrance.

This proves that Xu Yi’s foundation is laid very firmly.

Although he has not practiced for a long time and has been promoted to level 4 in less than a year, his foundation is still extremely solid because of his sufficient support for pills and the foundation of the little giant.

The transportation of the Great Zhoutian was continuous, and it was completed once in a short while.

But at this time, Xu Yi did not end his practice, but immediately took a top-quality Qi-gathering Pill.

The huge medicinal power was immediately converted into true qi, causing Xu Yi's true qi, which was already close to exhaustion, to activate again.

However, the flow rate of true air has slowed down a lot at this time.

When the true qi flows to a certain place, Xu Yi's thoughts move slightly, and the true qi immediately pauses.

"boom……"

The true energy in the body was as if it had stepped on the brakes and instantly stirred up.

The meridians at that point were even more shaking, as if there was a big hammer that was constantly hitting the meridians. The aftermath of the shock made the meridians open and close, and it was extremely uncomfortable.

A trace of pain flashed across Xu Yi's face, but he did not stop, but instead became more and more intensely stimulating the meridians here.

It took a full ten breaths, but in Xu Yi's feeling, it seemed like several years had passed.

Finally, the imprisoned true energy gradually dissipated and began to flow in the meridians again.

However, the originally turbulent place seemed to have a small pit.

Open your mouth and swallow a Tianling Pill.

Xu Yi reached out and lit it on his Tianling Cover again. A strange light shone down, making his body feel much more comfortable.

Tianling Pill plus nectar talisman.

Xu Yi was prepared and would never treat himself badly on this point.
