Lu Feiyu sighed softly, sensing the burning fire of his soul in his mind.

The raging fire was fierce and violent, and its fury had already taken over his entire soul.

At this moment, one-fifth of his soul was also burned away.

Once this soul fire appears, it is almost impossible to extinguish it by any means.

Unless, a soul wave that is thousands of times stronger than Lu Feiyu's strengthened soul suddenly presses down and extinguishes the soul fire directly with unreasonable and boundless force.

Just like cloth can be ignited by fire.

However, a piece of cloth that is large enough and heavy enough can extinguish the flames in an instant.

Thinking of this, Lu Feiyu smiled bitterly.

He is now the Taoist ancestor, and his soul is extremely powerful under the burning of the divine fire.

Although the world is vast, where can he find so much soul energy?

Could it be that Lu Feiyu really expected the other Dao Ancestors to spend tens of thousands of years collecting pure and huge soul energy for him, just like Yan Taizu did?

It's impossible to even think about it.

What's more, after this huge soul wave extinguishes the soul fire, it will press down on one's own soul.

The soul waves invaded, and Lu Feiyu might have all his consciousness and thoughts worn away by these boundless soul waves, turning him into a confused and idiot.

Thinking of this, Lu Feiyu shook his head, put away the bitter smile on his face, and his expression became firm in an instant.

Since he dared to ignite the divine fire, he was already prepared to have his soul fire burn out and to be doomed.

What's more, now that he was in the underworld, he had at least a tiny chance of survival.

Moreover, if the soul is not ignited, how can we turn the tide, save the collapsing building, and how can we save the billions of lives in the beast taming world?

Thinking of this, Lu Feiyu glanced into the distance with a deep gaze.

His gaze was far-reaching, penetrating the barrier between the two worlds and looking directly from the Tianyuan world to the Beast Taming world.

There, there was wailing everywhere, war everywhere, death and crying everywhere.
