Lei Luo was now in a slightly larger pit, and beside them lay several shriveled corpses.

In front of these corpses were those red-eyed beasts, and after they found the intruder, they all rushed forward without fear of death, and naturally they were all killed by them, and then used as nourishment for the Shura Sword.

Feeling the trace of black gas coming from the Shura Sword, Lei Luo was used to seeing strange things, and after checking the surroundings, he continued to move towards the depths of the cave.

After fighting with these black beasts, he found that there are still some differences between these black-haired and black-skinned beasts and demon beasts, and after the cultivation of demon beasts is improved, their spiritual intelligence will gradually increase, at least they will know how to retreat and escape.

But these black beasts, the aura of their bodies has reached the seventh, eighth, or even ninth layers of Qi training, but they have no intelligence at all except for their attack instincts, and they are really not afraid of death.

For example, a black python, although it will also coil and bite, but after that, this python will not be anything else, even the most basic latent snake monster will not.

There is also a black giant tiger that I encountered, whose breath has reached the ninth level of qi training, but as soon as he comes up, he will attack Lei Luo, and even if he is knocked away several times, he will still drag his seriously injured body and continue to attack, and he doesn't know how to escape at all.

In the end, Lei Luo killed this black tiger with a sword, and after devouring this black tiger, the black gas transmitted by the Shura sword was one point thicker than that of other demon beasts.

"These black gases should be the so-called demonic qi, I don't know if I have these demonic qi in my body, will it affect anything?" Lei Luo said as he looked at the Shura Sword in his hand.

Although he knew that the Dongyue Kingdom Immortal Cultivation Realm rejected demon cultivation, he did not emit the breath of a demon cultivator from his body, so he thought that others did not know that they had demonic qi in their bodies.

If after he killed so many beasts, his whole body was full of demonic energy, then it would be over, at least those Jindan elders in the sect would definitely suppress it, or even kill it.

Not long after Lei Luo left the pit, several more black tentacles came out of the ground, and these black tentacles still reached into the corpse of the beast, but naturally nothing was found.

As if to vent their anger, these black tentacles whipped at these shriveled corpses again, and after whipping the corpses, these black tentacles slowly sank under the ground and disappeared.

After submerging into the ground, these black tentacles move rapidly between the stone crevices in a special direction, as if the water in the crevices flowed unimpeded.

The black tentacles then moved along the cracks in the stone to a large cavern, where they met with the other tentacles and turned into a stout tentacle.

Then the tentacle stretched directly towards the stone wall of the cave, and then submerged into a huge black shadow that was attached to the stone wall of the cave.

After the tentacles submerged into the body, this black shadow opened a huge blood-red eye, this bloody eye emitted a breathtaking demonic red light, just like the eyes of a demon god, and a roar that seemed to contain anger came out of the black shadow, and then spread around.

The stalactites at the top of this karst cave began to shake and break apart after being affected by this roar, and some stone tips fell to the ground, and this huge black shadow slowly stretched out several tentacles, reaching into the cracks in the surrounding stones.

As Lei Luo advanced, he also heard this roar that seemed to contain endless resentment, and after feeling that this sound was coming from the deepest part of the cavern, his goal finally had a direction.

"Sure enough, there is a problem in this cave, but I don't know what kind of demon beast made this sound!" Lei Luo glanced at the depths of the cave, and then said slowly.

Maybe after staying in the sect for a long time, he will have some feelings of adventurism, he has no fear of this roar, and when he holds the Shura Sword in his hand, his whole body is even more high.

When he continued to advance a distance of more than a hundred zhang, he was besieged by a group of demon beasts, but this time the demon beasts besieging him were not large beasts, but a group of black rats.

Looking at the rat swarm in front of him, Lei Luo took a deep breath, then took off his shirt and turned on the Vajra Duel, and then his body was submerged in the rat swarm.

The black rat swarm seemed to know that the target they were going to kill was Lei Luo, and after drowning him, a huge black sphere was directly formed, and the surface of this sphere was all densely packed with rats, which looked particularly infiltrating.

"Drink!" A loud shout came from the ball surrounded by the rats, and then the entire ball burst directly, and the surrounding rats were scattered, and Lei Luo was armed with a broad-bladed giant sword to kill.

One beat, two beats, the broad-bladed giant sword was directly held high in Lei Luo's hand horizontally, and then used the side of the sword body to increase the striking area, and began to engage in a protracted battle with the surging rat swarm.

These rats didn't expect the target to be so tough, their invincible teeth actually gnawed at the target at all, but the black beast was not afraid of death, and the rat group naturally didn't know what to retreat from.

This time, Lei Luo killed for nearly an hour before he completely slapped the last few rats into meat sauce, and then took out the Shura Sword and began to devour it.

Although the number of these rats is huge, their attack power is not enough to cause damage to Lei Luo, who cultivates Vajra Duel, and with the help of the "Heavenly Dao Wanlun True Sutra" in his body, Lei Luo's true yuan can recover slowly, so after using the Vajra Duel for nearly an hour, there is no phenomenon of depletion of true yuan.

Of course, there are also some lucks, that is, there is no leader in the rat swarm, and if Lei Luo controls these rat swarms, they will be dispersed into small groups, using the characteristics of the cave to fight guerrilla warfare and keep attrition.

Consume the opponent's true essence through continuous harassment, and then after the opponent's true element is exhausted, they will rush to devour and drown it, so that anyone who comes here will not be able to bear it.

However, the number of these rats, if it weren't for Lei Luo, who had cultivated Vajra Duel, any foundation building monk would actually not be able to bear it, after all, there were almost no foundation building monks who specialized in cultivating the physical body, and they basically controlled magic weapons to fight the enemy.

Just as Lei Luo continued to want to move forward, he suddenly noticed a trace of unusual aura, and then the whole person fell on his stomach, and then used the breathing technique to hide his aura.

Lei Luo crouched on the ground, motionless, and then he saw several black tentacles sticking out of the cracks in the stones, and then rushing towards the swarm of rats.

When these tentacles approached the rat swarm, he saw some black gas flying out of the mouse corpses that were not devoured by the Shura Sword, and then directly absorbed by these black tentacles.

And the mouse corpses that had been devoured by the Shura Sword did not fly out of anything, and these black tentacles were directly whipped up, whipping these shriveled rat corpses to pieces.

At that moment, a brown rat, one-tenth the size of a black mouse, crawled out of the crack in the cave and crawled towards the corpses on the ground, apparently trying to eat them.

But when the mouse moved, a black tentacle directly wrapped around the brown mouse, and then in front of Lei Luo's eyes, black lines began to appear on the surface of the brown mouse's body, and these black lines spread towards the mouse's whole body.

After a while, the original brown mouse turned completely black, and its eyes turned blood-red.

And after this black mouse was put down by the black tentacles, its volume began to grow at a rate visible to the naked eye.

Then, the black tentacles did what they were supposed to do, and then disappeared directly into the cracks in the stone.

The black rat also burrowed towards a crack in the stone, and also disappeared, obviously not finding anyone nearby, otherwise according to the characteristics of these black beasts, it would not have left so easily.

"It turns out that the snooping aura I felt before was these black tentacles, and those beasts all evolved from animals, and these black tentacles are the culprits!"

Seeing what was happening in front of him, Lei Luo showed a hint of surprise.

Then he looked at the deepest part of the cave with a solemn expression, it was obvious that these black tentacles were very dangerous, but as soon as he thought of his goal, he took a step towards the depths without caring about the danger.
