Chen Lei knew that this was almost a dead end, and almost no external force could be used. He could only rely on his own true combat power.
Chen Lei became excited and sensed a hint of danger. He concentrated his attention and did not dare to be careless at all. After all, here, any negligence would lead to the danger of death.
Under such circumstances, the infant energy in Chen Lei's body became extremely lively and agile. He remained in an excited state and was stimulated all the time. The speed of his cultivation progress naturally accelerated.
Chen Lei released his divine consciousness and looked for traces of the monster.
Chen Lei had obtained a map in the Demon-Slaying City, which roughly outlined the terrain of the battlefield.
Chen Lei’s current cultivation level is not at the Yuanhun realm, so it would be very dangerous if he encounters a monster in the Yuanhun realm.
Especially in this battlefield, there are monsters at the ninth level of the Yuanhun Realm. Such monsters are not something Chen Lei can resist at this moment.
Therefore, Chen Lei could not enter the depths of the battlefield without permission. If he really wanted to, he would probably be killed in an instant.
Chen Lei also knew that with his own strength, he could not break into the depths of the battlefield. It was better for him to stay on the outskirts of the battlefield and hunt some weak monsters.
Chen Lei did not go deep into the Purgatory battlefield, but just flew along the periphery looking for monsters.
At this moment, in front of Chen Lei's eyes, it could almost be said to be a wilderness, with black earth and barren mountains everywhere, without a trace of green. The entire refining domain battlefield was desolate and silent, which could be said to be an eternal tone.
In such an environment, Chen Lei could feel that the infant energy in his body was consumed several times more than that in the outside world.
Chen Lei took every possible measure to reduce the consumption of his own infant energy, and all his actions were completed by relying on physical strength.
“Whoosh!”
Suddenly, a black monster more than two meters long emerged from the ground, with bloodthirsty light in its eyes, and pounced towards Chen Lei.
Chen Lei looked at the black monster and found that it was like a giant rat, covered with black hair, with small and fierce eyes, and claws like steel hooks, shining with cold light, which was very dangerous.
This monster, whose cultivation level was actually at the eighth level of the Nascent Soul Realm, pounced towards Chen Lei like a black lightning, locking its claws on Chen Lei's throat and trying to tear it apart.
Chen Lei only felt a gust of strong wind coming, the runes under his feet flashed, his body shape changed, and he directly avoided the attack.
Then, Chen Lei's mind moved, and a black lotus sword flew out, turning into a ray of cold light, and slashed at the huge rat-like monster.
“clang!”
A clear sound like cutting on metal was heard, followed by sparks. The fur on the rat-like monster's body had amazing defensive power, and Chen Lei's sword only left a shallow wound on its body.
This monster was injured by Chen Lei, and suddenly became ferocious. It turned around, turned into a black light, and pounced on Chen Lei again.
When Chen Lei saw the monster attacking him, he did not dare to be careless. With a thought, seven black lotus swords flew out at the same time and formed a sword formation in mid-air, which killed the black monster.
