The human city is very large, with a wall of hundreds of meters high, just like an ancient mountain located on the earth, majestic and majestic, with a kind of vicissitudes and heaviness accumulated over the years.∽↗

The huge human city has four gates in total, open in four directions, east, west, south, north and north. Each gate has a height of hundreds of meters and a width of tens of meters, which is amazing, but no guard is guarding because it is not necessary.

Chu Mu walked out of the north gate and saw that it was dry land, brown, as if blood was sedimented. Further away, there were mountain shadows.

With the expansion speed and moving forward quickly, Chu Mu was still astonishingly fast as he did not use the origin of the sword.

The killing giant beast is a unique beast in the killing world. It is often very large in size, and the huge body brings more powerful and powerful power. Therefore, the killing giant beast is amazing. At the same level, it is generally stronger than the human race.

In the killing world, local people account for the majority, and they are descendants left by outsiders a long time ago. They reproduce and develop gradually from generation to generation. Naturally, they are like the outside world, uneven, and there are geniuses. Unlike the cultivation that comes from the outside world, they are almost all geniuses.

Therefore, cultivators in the killing world go out to hunt and kill giant beasts to obtain killing secret patterns, often in groups. Only real geniuses can fight against or even kill killing giant beasts of the same level alone.

The levels of killing giant beasts are divided into low-level intermediate level and king level. The low-level level corresponds to the eternal realm, the intermediate level corresponds to the peerless realm, the advanced level corresponds to the great emperor realm, and the king level corresponds to the dominant realm.

The killing giant beasts in the killing world should be mostly low-level and middle-level. High-level killing giant beasts are often difficult to see, let alone the king-level killing giant beasts.

There are also levels of level among the low level. In order to correspond to the level of the cultivator, the low-level killing giant beasts are divided into twelve levels, one to nine levels correspond to the first level of the eternal heaven to the ninth level, and ten to twelfth levels correspond to three major combat powers. Among them, there is also a beast king level that represents the truly invincible realm of the eternal realm and can compete with the ordinary peerless realm of the first level.

Intermediate killing beasts are divided into nine levels, one to five levels correspond to one to five refinements, six to nine levels correspond to the small saint, the Great Saint, the Extreme Saint, and the Half-Step Emperor, and upwards are the Beast King level. Corresponding to the invincible level of the peerless realm, this powerful existence can escape even when facing the great emperor.

Not long after leaving the Human City, Chu Mu encountered the first killing beast.

At a height of ten meters, it is a black tiger covered with barbs.

The strength and size of the killing beast are often proportional. Ten meters of killing beasts are basically equal to the lower tenth level, which is equivalent to the dark star combat power of human cultivators, but it is a bit stronger than the normal dark star combat power.

Humans kill beasts. Beasts eat people. When the giant beasts see Chu Mu, they roar and suddenly flew over. The momentum is amazing and murderous intent is overwhelming. With an impact, the thick claws step out five amazing cold lights, each of which is half a meter long. They tear apart the sky, with amazing sharpness and murderous intent, and want to tear Chu Mu apart.

Chu Mu's height is less than two meters. Compared with this huge black tiger covered with barbed hair, it is very different, but Chu Mu could not see any panic on his face. The giant claws fell, and the five sharp cold lights were five claws, like five sword weapons slashing down.

A splendor flashed in his eyes, and he raised his left hand, and pointed out with a quick finger. His finger was like a sword, piercing through the sky, and then came first, piercing through the body of the killing beast.

The huge body fell to the ground, causing the earth to shake and dust to fly.

With one finger, he instantly killed the low-level ten-level killing giant beast, and his strength is amazing.

After the killing beast fell to the ground, its huge body released a faint light, which disappeared after a few breaths, leaving ten black iron auras, each exuding an astonishing murderous intent.

When Chu Mu grabbed it, he immediately grabbed ten black iron auras in his hand. The aura naturally merged into Chu Mu's palm and turned into ten light black marks. This is exactly the so-called secret killing pattern.

The black iron color is the black iron-level killing secret pattern, which is the lowest level killing secret pattern.

From Lin Meng's book, Chu Mu recorded forty-five black iron-level killing runes condensing methods. The least one requires twenty-five killing secret patterns. Of course, that is also the weakest black iron-level killing runes.

Keep moving forward and encounter the killing beast again.

The killing giant beast is a unique animal in the killing world. Strictly speaking, this is an energy-based beast with no flesh and blood. It is condensed mainly by the secret killing pattern. After being killed, the killing pattern will be left, and the rest will disappear between heaven and earth.

Not long after, Chu Mu killed several killing monsters and obtained more than twenty killing secret patterns. Theoretically, the lower-level first-level killing monsters have a black iron-level killing secret pattern, while the lower-level ten-level killing monsters have ten black iron-level killing secret patterns. However, it is not possible that the killing secret patterns can be maximized by killing the killing monsters. It may be just a few, and it may not be a single one, all depends on luck.

"First gather a killing rune to see."

As he said that, Chu Mu controlled twenty-five black iron-level killing secret patterns to quickly condensed in the method he already knew. With Chu Mu's ability, this was not a difficult thing, but it just required a lot of concentration.

The twenty-five black killing secret patterns were controlled by Chu Mu's consciousness, and they swam one after another, gradually intertwined and condensed, and finally turned into a black rune the size of a thumb. There were twenty-five traces on the rune, which looked very magical.

This black iron-level killing rune is called the Power Rune. As the name suggests, it is a rune that can enhance its own strength.

Chu Mu studied it carefully for a while, and then used his mind to control it to stimulate the power of this rune.

The runes seemed to burn, bursting out black light, like a ball of black flames, instantly entering Chu Mu's arm. Chu Mu suddenly felt a force permeating his whole body, and his own power was enhanced.

"Well, it's about 10% higher." Chu Mu felt it carefully and said to himself. Although he could feel that his body's soul power seemed to be strengthened by 10%, it had no improvement effect on Chu Mu's strength.

A 10% increase is an increase at the lowest level of the kill rune, which is the case no matter what level of the kill rune it is.

The black iron-level killing runes correspond to the level of the Eternal Realm, the bronze-level killing runes correspond to the level of the Peerless Realm, the silver-level killing runes correspond to the level of the Great Emperor Realm, and the gold-level runes correspond to the level of the Dominant Realm. Generally speaking, the increase of the black iron-level runes for the Eternal Realm is 10% to 50%, the increase of the bronze-level runes is 60% to 10%, the increase of the silver-level runes is 21% to 15%, and the increase of the golden-level runes is 160% to 20%. These increase is the most basic increase of single runes.

Such an increase is very obvious. If the invincible person in the Eternal Realm gets the increase of the Black Iron-level killing runes, his strength will be significantly improved and he will become stronger. If he gets the increase of the bronze-level runes, he will become stronger.

This is the world of the strong. Every increase in strength, speed or any aspect of each point will be exerted by them with their maximization advantage.

The reason why this powerful rune has not increased Chu Mu's strength is very simple, because Chu Mu's cultivation has surpassed the eternal realm and reached the peerless realm, whether it is Yuanli, physical or spiritual will.

"You have to hunt the intermediate killing beast." Chu Mu said to himself. The black iron-level killing runes are ineffective against him, so he naturally doesn't care about it.

The area where the intermediate killing monsters are located is even far away from the human city.

Move forward. If you encounter a killing beast on the road ahead, you will kill it and obtain some black iron-level killing secret patterns. If you see it from a distance, you will ignore it.

Chu Mu never expected that when he stepped into the intermediate killing monster area, he would encounter someone who had cheated out of five hundred pieces of law crystals from his hands. When the man saw Chu Mu, he also showed an unexpected look and immediately turned into a grim smile.

"It seems that I'm lucky today." The middle-aged man laughed, his eyes full of astonishing murderous intent.

Anyone who has been in the killing world for a long time will be covered with a strong murderous aura after many battles and killings.

"I just broke through to the Peerless Realm, but I dared to come here alone. It seems that I have great confidence in my strength." Four people formed a five-person team with the middle-aged man. Among them, the highest cultivation level is the Three Refining Peerless. With a sharp vision, you can see at a glance that Chu Mu's cultivation level has just broken through to the Peerless Realm.

The highest cultivation level of these five people is the third refinement peerless, two second refinement peerless and two first refinement peerless. They all have a silver sword embroidered on their chests. This is the logo of the Giant Sword Sect, indicating that these five people are all from the Giant Sword Sect.

"Brothers, the five hundred law crystals we had for eating, drinking and having fun not long ago were obtained from him." The middle-aged man pointed at Chu Mu and smiled at the other four.

"So that's it. It just happened that the law crystals were used up. Boy, I'll borrow some more flowers. Not much, just give me four or five thousand." The other one said to Chu Mu with a grin.

"Boy, you should be strong enough to come here. You should also kill some low-level killing monsters and hand over all the black iron-level killing secret patterns."

"In my opinion, let him hand over the space ring obediently."
