With a cloudless sky, an endless verdant grassland, and an extremely cold Arctic snow behind him, Chen Lang felt the warmth on his face, which was really weird.

There was no longer a howling wind in the sky, the air was filled with a refreshing smell of grass and trees, Chen Lang, who took a deep breath, was greatly refreshed, and the rich aura between heaven and earth made him feel that his cultivation had improved again.

Eager to step into the grassland, Chen Lang suddenly felt a pain, and when he looked down, a sword-like blade of grass actually cut through his thigh.

A hint of surprise flashed in his eyes, Chen Lang stretched out his hand, this blade of grass was extremely tough, and he couldn't break it after several attempts, until he used his mana to cut it off.

Chen Lang carefully looked at the blood-stained blade of grass, and used his mana to twist it lightly, and it shattered like metal, and it couldn't be crushed into mud at all. As far as the eye can see, the entire grassland is covered with this kind of grass, and those who have not practiced enter the grassland and walk a distance, their legs are afraid that their flesh and blood will be blurred.

From Xu Tian's diary, he learned that this grassland is called Jianhai Grassland, and there are hundreds of thousands of iron-eating rats that feed on the Sword Leaf Grass are entrenched here.

The Iron Devouring Rat is a first-order demon beast whose strength is comparable to that of the late stage of Qi refining, of course one or two are not terrifying, but if thousands, or even tens of thousands, come to besiege a monk, it will be terrifying.

The best way to get through the grasslands is to fly in the air, but be fast, slow and you will face thousands of iron rats in the air.

In the early stage of foundation building, monks were able to fly in the sky, but Chen Lang had not yet cultivated the spell of soaring clouds and mist, and he did not need to cast spells to urge the magic weapon of flight, but Chen Lang did not have this kind of magic weapon.

Xu Tian had prepared a superb flying magic weapon before the Ice Demon Old Monster Cave Mansion was opened, but unfortunately it was destroyed when he escaped into the Arctic Snow Region.

A difficult problem is in front of Chen Lang, how to leave the Jianhai Grassland unharmed?

Suddenly, a rustling sound reached Chen Lang's ears, and a fist-like demon rat jumped up suddenly, heading straight for Chen Lang's throat and biting it.

A cold light flashed in Chen Lang's eyes, and a cold air was stimulated from his fingers, and it was right in the middle of the iron rat, freezing it into an ice sculpture.

The difference between the iron eater rat and the ordinary rat is not very big, that is, the front teeth are particularly prominent, and it looks sharp, and what is particularly strange is that the iron eater rat has no eyes, Chen Lang guessed that this kind of monster beast may be able to distinguish the direction by smell, or sound.

Suddenly, the sound in the grass became noisy, and it seemed that a large wave of iron-eating rats was coming.

Chen Lang couldn't help but take a step back and sacrifice Juyun Peak. With a loud bang, waves of blood splashed from the bottom of the mountain, and I don't know how many iron-devouring rats died at the bottom of the mountain. But there were still hundreds of black shadows that jumped up, and they were not afraid of death, and they were very crazy.

Not only that, the iron-devouring rats that came later submerged Juyun Peak, and the sharp front teeth frantically gnawed at the peak, and the gravel fell with a bang.

Even if it was Chen Lang, he had to be scared in the face of this scene, and while he retreated to the back of the snow field, he pointed at Juyun Feng violently. Juyun Peak shrank to the size of a palm, and shot towards Chen Lang quickly, Chen Lang, who was running for his life, grabbed Juyun Peak and stuffed it into a storage bag without looking, only a few steps away from the snow field.

There was no danger of retreating into the snowy Arctic region, and the iron-eating rats cowered at the distance of a line, as if there was something in front of them that frightened them. But in the end, a few iron-eating rats lost their control and rushed into the snowy fields filled with cold winds, and they instantly turned into ice sculptures, completely lifeless.

"This iron rat seems to be particularly afraid of the cold. Chen Lang rubbed his chin and thought of a good idea. There was a thousand-year-old Xuan Ice in the storage bag, and the cold air emitted was so cold that even he who had cultivated the Taiyin Cold Ice Technique couldn't bear it, how would the Iron Devouring Rat with negative cold attribute tolerance react?

Chen Lang's face showed a look of determination, and he boldly walked towards the rat tide with a thousand-year-old Xuan Bing. In just a short period of time, the number of iron-devouring rats has increased geometrically, almost tens of thousands, and the squeaky sound is terrifying, Chen Lang can't help but want to throw Juyun Peak to smash the iron-devouring rats to pieces.

If you stand at this border and smash the Iron Eater Rat with Juyun Peak, will it attract all the Iron Devouring Rat entrenched in the Sword Sea Grassland, so as to kill it cleanly?

Chen Lang also thinks about it, this kind of thing is difficult to achieve. Demon beasts are not completely intelligent, they will avoid danger.

Chen Lang tentatively took a step forward, and the rat tide hesitated and stepped back for some distance. As a result, Chen Lang took three steps in a row, and the rat tide kept retreating.

Feasible!

Chen Lang had a happy expression on his face and strode forward, the speed of which caused the Iron Eater to become chaotic. They squeaked, some scattered in groups, and a few black shadows attacked Chen Lang.

Chen Lang instinctively wanted to fight back, but hesitated and gave up, believing that the cold air emitted by the thousand-year-old Xuan Ice could restrain the Iron Devouring Rat.

Sure enough, Chen Lang guessed correctly.

The black shadow that attacked him suddenly stopped, as if he was restrained by some invisible force, and his body visibly condensed thin ice, turning into ice sculptures and falling from the sky.

The danger of the Sword Sea Grassland is gone!

Protect your body from sword leaf grass and you will be foolproof.

The body protection qi circulated on the surface of the body, and Chen Lang strode forward with his head held high, like an emperor on patrol, and the iron-devouring rats all over the mountains were full of ants.

Half an hour passed.

An hour passed.

Three hours passed.

There was no sign that the rat tide was going to disperse, and it gathered like a pilgrimage, and Chen Lang complained bitterly.

The cold air emitted by the thousand-year-old Xuan Ice was too cold, Chen Lang felt that the bones of his whole body were about to freeze, and in the Arctic Snow Region, he had not been tortured so inhumanly. Whenever he showed signs of stuffing the thousand-year-old Xuan Ice back into the storage bag, the Iron Devouring Rat seized the opportunity to attack, making Chen Lang can't help but want to jump and scold his mother.

At the end of the road, Chen Lang's whole body was numb, and he walked out like a machine holding the thousand-year-old Xuanbing until he heard the sound of a fight.

Chen Lang's eyes suddenly focused, and he walked quickly in the direction where the voice came from, driving a black tide.

A huge iron-devouring rat was storming a cyan light cluster, and there were two people in the light cluster, a white-bearded old man with a rickety figure, and a girl in a yellow dress with a beautiful face, the girl was holding three yellow runes, staring nervously at the crumbling, flickering light cluster.

Another old man, holding a gray animal skin in the shape of a rune paper between his fingers, closed his eyes, frowned, and said something in his mouth, as if he was preparing a killing move.

The girl discovered Chen Lang's existence, and her happy face turned pale in an instant, and she trembled and pointed at the endless rat tide behind Chen Lang in horror.
