Zhou Xing had expected such an event earlier. As he retreated quickly, he immediately raised the iron-hearted cauldron and shouted, "Mountain!"

Immediately, the Tiexin Ding faced the storm and immediately covered Zhou Xing like a hill. Tiexinding is also a magic weapon, and the gray mist is designed to break the magic weapon. Any magic weapon will be wiped out by the gray mist, but Zhou Xing still did it, because he has faith in Tiexinding! Just like when the real Guangling shot him, his first reaction was to protect himself with an iron-hearted cauldron.

clang! ...

Something incredible happened!

When the gray mist hit the iron-hearted cauldron, it didn't pass through, and it was like hitting the south wall with the sound of gold and iron clashing.

When Zhou Xing saw it, his heart was exasperated. Sure enough, this weird gray mist latte heart tripe!

"Impossible!" Li Nan exclaimed when he saw this scene not far away.

clang! clang! clang! ...

The gray fog was blocked by the iron-hearted cauldron, and it seemed to be very unwilling, so it hit hard, one after another, as if it was ringing a bell.

Although Tie Xin Ding blocked the attack, Zhou Xing worried that a long time would not be good for Bao Ding, so he immediately launched a counterattack based on his previous observations and thoughts, and released all the Black King insects with a thought.

The reason why Zhou Xing released the black king bug was because he found that the gray mist and the black king bug have a common feature, that is, it is very good at destroying magic weapons, and when the number of black king bugs reaches thousands of levels, it seems that It's like a black screen covering the sky, which has similarities with the gray fog. Therefore, he boldly speculates that the gray fog is probably composed of countless strange bugs like the black king bug, but these gray bugs are too small. , As small as a grain of sand, even smaller than a grain of sand.

All of this is Zhou Xing's bold speculation, and he can't say how certain he is, but at the moment of life and death, he naturally has to choose the biggest option, which is to kill the insect.

He who has studied The Art of Royal Beasts knows that beasts have natural coercion, and there are also strict hierarchical systems among insects. He is convinced that the evolving Black Emperor insects from the fairy house have already climbed. The peak of the Zerg, although it has not reached the top level, at least it should not be weaker than this gray fog.

In the blink of an eye, thousands of black emperor insects swarmed out and collided with the gray mist. Zhou Xing could clearly perceive everything happening outside with his naked eyes and spiritual sense, knowing that the black emperor insect and gray mist had a desperate fight. A large number of black king worms died in the screams, like a magic weapon, but also a large amount of gray mist was defeated and was crushed by the black king fangs and swallowed into the abdomen.

That's right! The gray fog is really composed of tens of thousands of gray monsters. They are so small that they are difficult to catch once they spread. That's why there is a scene of disappearing in place many times before.

It turns out that these insects have a strong attack, but their digestion and continuous combat capabilities are not strong. Once they succeed, they will be broken into pieces and regroup after a period of time to win by numbers. In order to frighten the enemy, they even learned to mimic. When they gather together, they can roughly form the outline of a person, just like a gray mist person.

This was a desperate fight, and Zhou Xing could not help much, but he had confidence in the Super Black Emperor Worm he had cultivated, just as he had confidence in Tie Xin Ding.

The fighting of the two monsters was violent and short. After only five breaths, the victory or defeat was divided. The Black King insect killed more than half of the gray insects at the cost of one-fifth of the death. See the remaining gray insects. Not an opponent, turn around and run. They suffered heavy losses and urgently needed to replenish their energy. Since they couldn't break the iron-hearted cauldron, they turned around and flew towards Li Nan like lightning.

When Li Nan saw it, he was so scared that he immediately opened the formation and locked the bugs again. Zhou Xing immediately stretched out a finger and said softly: "Done!"

In an instant, the concentration technique came into the body, Li Nan felt his movements were sluggish, and he was busy running his whole body to resist, but it took at least one breath to regain his mobility. However, this short breath time is enough for the gray worms to fly to Li Nan. In front of her, then, the gray worms staged an amazing scene once again, penetrating her body, and then scattered, and did not dare to come out, and Li Nan's body also fell apart in an instant and disappeared in smoke.

"It deserves to hurt others and yourself!" Zhou Xing cursed, took the big tripod, and showed up.

He didn't rush to put away the black king worms, but let them fly by his side to prevent the gray worms from returning and kill him with a carbine.

As soon as the person in charge of the formation died, the great formation did not break down. The previous four people each took out two magic weapons to consolidate the formation. At this time, the eight magic weapons became Zhou Xing's gain, and he took it into his bag. Of course, everyone's ring, because the food that did not belong to the gray worms, has been preserved intact, and it has naturally become Zhou Xing's pocket, and it is considered a small fortune.

Zhou Xing was very happy, but he was still on guard. After the five poisons and gray worms, there might be danger waiting for him.

He looked around and waited for a long time, but he didn't see any movement. Instead, the exercise in the sky suddenly fell to the ground.

Zhou Xing was overjoyed, carefully picked up the exercise book, and took a closer look, it turned out to be a heavenly exercise, named "Huan Shen Jue".

Anyway, the enemy was gone for a while, and in a relatively safe environment, Zhou Xing released two more battle puppets to serve as guards, and then eagerly opened the book and read it.

"Phantom God Technique" is a technique that can cause the enemy to hallucinate. This kind of technique is not uncommon, but most of them are of lower rank and have general effects. The low-level monks have no effect on the high-level monks. It is easy to be backlashed. If the monks of the same rank are used between them, the effect is often very limited, and it is very tasteless. However, high-rank monks and low-rank monks do not need this kind of exercises, so magical techniques have always been unpopular. Few people practice, and masters are even rarer.

However, "Huan Shen Jue" belongs to the heavenly-level exercises, its status is transcendence, and it is completely different from ordinary glamorous bastards. There is a difference between cloud and mud. Zhou Xing only read two pages and became hooked, because he found that this exercise was too far. Powerful, low-level cultivators have extremely high success rates and extremely powerful effects when used against high-level cultivators. Even if they fail occasionally, they will not suffer backlash. Whether it is attacking, killing or running away, "Huan Shen Jue" is an extremely powerful and practical technique.

After Zhou Xing learned about this technique, he immersed himself in reading it. When he imprinted all the contents of the book deeply in his mind, he immediately began to practice.

In the blink of an eye, three days later, Zhou Xing opened his eyes again. Unlike before, there was a hint of red light in both of his eyes, and the red light disappeared after the effort was collected.

"It's worthy of the Heaven-Rank Cultivation Technique. Fortunately, you have already started." Zhou Xing smiled.
