Lu Yu did not move without permission, but remained in ambush in a mountain forest, sitting still like an old monk, not showing any breath.
Here, he is not invincible. Even if there is a method like the Heavenly Emperor's True Fire, Lu Yu will not use it easily.
"My soul has nearly doubled in size, but there is still a long way to go before reaching the bottleneck."
Lu Yu frowned slightly, but he was still thinking about how to make a breakthrough.
The inheritance given to him by Marquis Que only contained martial arts, but no cultivation techniques. This resulted in Lu Yu having no way of knowing how to break through to the human-immortal realm in ancient times.
At this moment, a purple pillar of luck soared into the sky and fell into Lu Yu's eyes.
Although there are a few jet-black pillars of luck surrounding them, they are nothing compared to this.
Lu Yu only saw such a light beam of luck in the original purple and green immortals.
"A big shot is here!" Lu Yu's heart skipped a beat, and he held his breath and sneaked in.
In the northernmost part of the city, there is a magnificent palace.
There are still traces of previous habitation here, and all the buildings here are extremely exquisite and magnificent.
It's just that the people living here now are a group of bloodthirsty and terrifying monsters.
In the deepest part of the palace, there is a high altar.
On the altar, a bloody heart appeared, beating slowly.
Every time it beats, the surrounding air seems to be filled with vibrations and thumping sounds.
There are several rows of demons around the altar. They kneel on the ground and chant ancient and complicated spells to the heart.
Lu Yu quietly approached the altar, hiding his aura so that no demons could notice him.
"The sacrifices needed for the Demon Ancestor's heart have been gathered."
"After a while, the Demon Ancestor will come...Dianxiandai...can't hold it."
Beside the altar, several high-level demons were talking, with uncontrollable excitement in their words.
The demonic energy soaring into the sky began to spread around the altar.
Lu Yu was hiding in a bush and suddenly felt that the aura was a bit familiar.
"Ancestor Earth Evil Demon? Could it be that the ancient demons of the past were born from here?" Lu Yu was shocked.
Everyone in the heaven thinks that the ancient demon is a visitor from outside the world, and no one can tell the true origin of the ancient demon.
But now, Lu Yu thought carefully for a moment again, and he was able to confirm that the demonic energy emitted by the heart in front of him was the aura of the Earth Demon Ancestor.
"who!"
Suddenly, one of the high-level Demon Ancestors looked warily at the grass where Lu Yu was.
He grabbed it casually, and a black flame suddenly erupted from the patch of grass, burning the patch of grass.
After the flames passed, nothing but ashes remained.
"It's me who is worrying too much." The high-level Demon Ancestor said in a deep voice: "Recently, people from the Heavenly Court have been coming to several surrounding towns. You and I will watch the four gates of the city and we must not let the people from the Heavenly Court disturb the ceremony."
Several high-level demon ancestors quickly left the area around the altar.
However, Lu Yu still did not act recklessly.
The moment the high-level demon took action, he had already changed positions.
He waited for a long time, and after a full hour, he figured out the patrol patterns of the demons.
Just when the last group of demons passed by him, Lu Yu's eyes suddenly let out a gleam of light.
"Now!" Lu Yu directly summoned the shadow of Hades and slapped the demon kneeling next to the altar into blood foam.
In a flash of lightning, Lu Yu had already arrived in front of the heart.
