At the same time, those red fire spirit insects also rushed towards Qin Cheng.

The buzzing sound was deafening, and the number was many times greater than the 100,000 they encountered before.

With one step forward, Qin Cheng's whole body exploded with thunder, transforming into the Lord of Thunder again and rushing into these spiritual insects.

Qianjun's thunder body rotated rapidly. Under Qin Cheng's wanton stimulation, countless thunder rays poured out along Qin Cheng's body, turning into thunder snakes and surging in all directions.

Kaka!

The thunder snake roared, and wherever it passed, the spiritual insects were scorched black and fell to the ground trembling.

Thunder danced wildly in the cave, and the eyes were filled with brilliant lightning that people dared not look directly at.

Qin Cheng was suspended in the air in the cave, advancing slowly but firmly.

Wherever they passed, spiritual insects fell one after another, like a heavy downpour, piling up a thick layer of corpses on the ground.

Ten thousand, one hundred thousand, two hundred thousand.

In the short time it took to enter the cave, Qin Cheng had killed countless spiritual insects.

Countless thunder snakes were jumping around. If Qin Cheng had not deliberately controlled it, this section of the cave would have been shattered, revealing the deep and dark void cracks inside.

At this time, the Firework Demon Rat was sitting proudly on Qin Cheng's shoulder, his little eyes bright and his expression full of pride.

From time to time, it would make a squeaking sound towards the spirit worm, as if to say, you didn't have a good time fighting it before, but now you are here again.

In the end, these red fire spirit insects finally couldn't hold on any longer.

They no longer attacked crazily, but began to turn into wisps of red mist and began to flee in all directions, just like the group of spiritual insects Qin Cheng had encountered before.

Qin Cheng shook his head and did not pursue these fearful spirit insects. He collected the aura of the ultimate fire with a wave of his hand and cultivated the fourteenth ultimate fire. Then he rolled the corpses of the spirit insects into the storage bag.

And after passing through this cave, there are still several forked roads to the end.

"The concentration of fire breath here is indeed much higher than in the previous place."

Without these scratching insects, Qin Cheng's spiritual consciousness spread out and sensed his surroundings.

In the center of this cave, there is also a spatial light curtain, and that light curtain is the dividing point between the two flames.

But what makes Qin Cheng regretful is that after passing through this sea of ​​insects, the cave still has no end in sight.

It seems that I just came to a place closer to the core.

"Little guy, it's your turn to take action."

After patting the demon rat on his shoulder, grabbing the soft skin from its neck and taking it off, Qin Cheng spoke.

The Firework Demon Rat also screamed excitedly, and then continued running.

In this cave area, the number of red fire spirit insects is obviously greater than outside.

However, it seems that these spiritual insects have a special way of transmitting information.

When they saw Qin Cheng, they all stayed away, and no spiritual insects took the initiative to attack them.

This thing turns out to be about bullying the weak and fearing the strong?

In addition, Qincheng is also a bit strange.

At the other end of the cave is a whirlpool of flames. It would not be unusual if some red fire spirit insects accidentally entered it.

But with such a large number of things, can the fire energy in the cave really feed millions of spiritual insects?

After all, these guys all feed on fire. Not only did they not starve to death, but they lived very energetically.

"Zhizhi."

Just when Qin Cheng was thinking wildly, the Firework Demon Rat in front of him suddenly stopped.

In front of a rock wall, it once again showed a distressed look. It looked ahead for a while, then looked here again, as if the choice between the two made it very difficult.

"Are these two places where the smell of fire is very strong?"

After being in contact with the demon rat for a long time, Qin Cheng can roughly understand what this little guy means.

But in front of him, there is just an extremely ordinary rock wall. The flame smell here is very strong?

Qin Cheng raised his eyebrows, walked over and put his hand on the rock wall.

Then Qin Cheng's expression suddenly changed.

It's actually really weird.

He had been spreading his consciousness before and didn't notice anything wrong here.

But when I put my hand on the crystal of unknown structure on the rock wall, I immediately realized that something was wrong in this area.

Across the rock wall, deep inside, there were wisps of flames surging, extremely pure and extremely rich.

He glanced at the little guy on the ground.

This fire demon rat is indeed a demon beast that specializes in exploring the breath of fire. It is indeed quite powerful.

But what is inside this rock wall?

Why don't you try splitting it.

Qin Cheng frowned slightly, turned his palm over, and a bronze sword appeared in his hand.

But soon, Qin Cheng put away the bronze sword again.

"No, this rock wall seems a little different."

Qin Cheng's mind turned, he touched the rock wall in front of him with his palm, and then compared the position behind him, his eyes suddenly changed.

The Heavenly Ming Eye and the Divine Eye were opened at the same time, looking at the rock wall.

And under the divine eyes that deciphered all illusions, a surprising scene appeared.
