Looking for a fixed point, Xu Yi smashed hundreds of punches in a series of times.

Boom...

As hard as hard iron, he also broke out some scars, but there was no sign of rupture.

With a clang, the sword energy was surging, and the Qiushui Sword instantly drew out three swords, all of which hit Xu Yi's crazy force, and it was still difficult to penetrate.

"My grass!"

Xu Yi was furious, gathered his life's strength, punched, and a roar, and a crackle, the fist bones broke, a large amount of blood flew away, and the iron wall remained the same.

"I'll go to you!"

Xu Yi was almost crazy and raised his punch high again. He was about to fall, but suddenly he suddenly fell into the air and a strange change occurred on the iron wall.

The blood dissolved into the iron wall and quickly turned into blood lines, spreading half a square in an instant.

What made Xu Yi dizzy was that a small abacus pattern appeared where he just fell from his fist. His thoughts flew around, and his lightning and fire were flashing. Xu Yi remembered it, which was exactly the same as the last golden abacus emblem in the number theory notes he got.

If you look closely, next to the small abacus is a line of small characters - the last writing of the unfilial disciple Guanglingzi.

The words in the cliff cast a bright color on Xu Yi's almost desperate heart.

He no longer dared to delay, break his skin and let the blood spray. Soon, the blood lines on the wall became more and more dense. Soon, the entire wall gradually filled.

Gradually, the bloodline gathered into words.

"This is carved with your fingers!"

Xue Zi said in a chill, unable to believe her eyes.

This wall is obviously cast with heavy iron mixed with unusual iron, which is extremely hard and tough. It is as sharp as the autumn water sword and cannot be broken, which shows its sharpness.

The text on the wall clearly has the mark of fingering.

There are people in the world who can leave words on this wall that cannot be broken by their fingers alone. How terrifying it would be.

Xu Yi did not pay attention to how the text on the wall came from, and all his attention was attracted by the content on the text.

"Dog thief, dog thief, if you cannot eat like meat in your life, you will take your soul if you die!"

"My teacher is above. The unfilial disciple Guanglingzi worships far away!"

There were only these two whispers on the entire wall, and I was actually a mathematical argument like that of that mathematical note.

After reading it all in one go, endless joy suddenly erupted in Xu Yi's heart!

He was scolded by him and stepped into the mud pit. He suddenly lifted it up to his head.

What is the road that is boundless? This is the road that is boundless!

He even felt a sense of destiny from deep inside his heart, such as the cycle of fate and fate.

It turns out that the words on the wall are actually an argument, an argument about the unity of all circles.

Guanglingzi proposed a hypothesis, how to make the five rings pass by at the same certain point.

If it weren't for the previous study of Guiyuanpu, Xu Yi would probably find it difficult to understand the arguments on the wall. With this experience, he felt a natural feeling about the arguments on the wall.

In other words, this cause and effect is God's will.

It turns out that Guanglingzi is a strange man, three hundred years ago, and he was a sensational figure for the time.

Mathematics, mechanisms, Qimen, and Bagua, all are exquisite and all are understandable, and they are famous masters.

Three hundred years ago, in Chunyang Palace, Jiang Hentian was designed by the emperor. With peerless force, he barely broke out of the palace, fled far away from the capital, fled back to his hometown in Guanzhong, and soon lived and died.

The Jiang family is a giant clan in the world, and the influence is extraordinary. The emperor attacked and killed Jiang Hentian. No matter who knows, he has to say "ingratitude".

As Jiang Hentian escaped, the Jiang family knew about this. If it was told to the world, the emperor would definitely lose face.

However, since the wise and powerful man is gone, it will lose its meaning to the family.

At that time, after careful consideration, the head of the Jiang family reported to the court that Jiang Hentian died of illness.

The Jiang family conveyed goodwill, and the emperor naturally accepted it. Whether it was to truly repay Jiang Hetian to protect the world, or to show it to the world, the Tian family gave countless treasures.

The Jiang family also became very famous because of this.

Jiang Hentian won the supreme reputation for the Jiang family. Since he was alive and dead, he should be buried with great pleasure.

The Jiang family then paid a lot of money to hire famous craftsmen from all over the world. Guanglingzi was already famous at that time. He was grateful to Jiang Hentian for his lifetime. He went to the Jiang family to announce the list and took over the important task of supervising Jiang Hentian's tomb.

After nearly ten years of time, Guanglingzi finally found a Yin vein in the Huiyin Mountain, and chose Jiang Hentian's tomb here.

After ten years, the tomb was finally cast. According to the rules at that time, all the craftsmen who built the tomb must take the Forget Heart Pill and forget about casting the tomb in the past ten years.

However, as a wealthy family, and Jiang Hentian's tomb, in addition to leaving Jiang Hentian's corpse and bones as a place for trials by the Jiang family.

Therefore, plant treasure medicines in it and cultivate them carefully.

In addition, Jiang Hentian's cultivation was shocking. After his death, his skeletons were very precious. The head of the Jiang family even carried Guanglingzi on his back. After the tomb was completed, he privately stolen Yin River and built a hanging coffin to warm up Jiang Hentian's skeletons.

The Jiang family has tried their best and spent countless money. How can such a treasure-rich tomb, a mere heart-forgotten pill, make it feel at ease?

The head of the Jiang family did not hesitate to launch the forbidden technique, which made tens of thousands of civilians turn into powder overnight.

Before performing the technique, he even used the inspection of the tomb chamber for the people to introduce Guanglingzi into this secret room for a large amount of money, trapping Guanglingzi to death.

It was not until two hundred years ago that a Taoist who was born in the Danding Sect accidentally discovered this giant tomb, saw the wonder of the Yin Coffin, and had the idea of ​​being a master of heaven, leaving a lead in the classics, which led to Xu Yi, who was as famous as the tomb to explore.

Coincidentally, the author of the secret book about the circumstance obtained by Xu Yi has a great relationship with Guanglingzi.

Now, he crashed into the place where Guanglingzi died, stained the wall with blood, and found Guanglingzi's remaining text. It was really in the dark, and he had the will of God.

Guanglingzi was trapped in death and made some efforts.

Perhaps he spent too much effort on the mathematics mechanism, Qimen Bagua, and other strange techniques, so that his martial arts were a bit abandoned. His genius was only at the Qihai Realm.

However, even the cultivation level of Qihai Realm, relying on what he learned, was enough to stand proudly in the world. Even the Jiang family was as strong as the one who dared not to fight him head-on, but chose to trick him into entering the secret room. After he died, he entered and took the Sumeru Ring.

At the beginning of the ban, Guanglingzi had made no efforts. He had tried all kinds of formations and weapons, but he could not break the secret room that the Jiang family had been prepared carefully.

At the end, I barely remembered the way of mathematics. After a long time of mental calculation, I came up with the conclusion that these five circles were beyond fixed points, and used a special finger cover, using the wall as paper and the finger as the pen to record it.

However, God's will is sometimes exhausted. Although Guanglingzi thought of the wonder of the combined attack, he did not obtain the number theory and could not exhaust the wonder of all the circles.
