"Senior, should you agree now?" Feng Shenyu asked.

"Okay, I promise you, but you must swear an oath first." The red-haired old man saw that Lu Chen and Feng Shenyu were both inferior to others, so he nodded and said.

Lu Chen and Feng Shenyu looked at each other, hesitated for a moment, and then made the Heart Demon Oath without any hesitation.

"Okay, decisive enough!"

The red-haired old man admired twice when he saw this, and then made the inner demon oath.

You must know that once the inner demon oath is made, it will be accepted by the rules of heaven and earth. If you regret it, the oath you made will appear in the future catastrophe, which is definitely a disaster.

Therefore, no one dares to violate the inner demon's oath.

"Senior, I will give you these two items first, and you will remove the blood poison for me first. What do you think?" Feng Shenyu said immediately.

"Of course." The red-haired old man glanced at Lu Chen, then said to Feng Shenyu with a smile, 'Come forward.'

Feng Shenyu nodded, walked up, and handed over the Sun Essence Stone and Dragon Blood Stone.

"very good!"

The red-haired old man nodded and said, "Put them on the Hades Stone."

"yes."

After hearing this, Feng Shenyu didn't hesitate and placed the Sun Essence Stone and Dragon Blood Stone on top of the Ming Stone.

Immediately afterwards, the red-haired old man stretched out a dry palm that looked like a chicken's claw. He grabbed it through the underworld stone and made two "chichi" sounds, and the sun essence stone and dragon blood stone merged into it.

"Okay, little guy, I will remove the blood poison from you now."

Then, he glanced at Feng Shenyu, rolled his hands, and ejected a drop of Yin Hong's blood, which fell on Feng Shenyu's hand.

Feng Shenyu was startled.

"Do not move."

However, the red-haired old man suddenly spoke up.

Feng Shenyu calmed down after hearing this, and then saw the drop of blood sinking into his palm.

"Ah." Immediately afterwards, Feng Shenyu let out a cry of pain.

Then, Lu Chen could clearly see that Feng Shenyu's skin turned blood red, with blood seeping out, and the blood vessels bulging, like blood-red worms squirming, and it looked particularly scary.

There was a hissing sound, and then a blood-red insect crawled out of his palm.

"Blood Gu?"

Lu Chen and Feng Shenyu were both startled when they saw this, and the latter could not hide the excitement on his brows.

"Okay, your blood Gu has been taken out by me. Next, it's your turn." The red-haired old man said to Feng Shenyu with a smile.

After saying this, the old man turned his attention to Lu Chen.

"You can remove the blood poison for me first!"

Lu Chen glanced at this old man and said calmly and calmly.

"That's fine."

The red-haired old man nodded meaningfully, as if he was not afraid that Lu Chen would regret it.

A drop of blood flew out of the underworld stone and landed on Lu Chen's palm.

A "chi" sound;

Lu Chen saw the blood sinking into his palm, and felt a heartbreaking pain.

Immediately afterwards, he saw the drop of blood follow the blood veins and enter the heart.

There, there was a blood-red bug.

This is the blood Gu in Lu Chen's body.

Soon, the blood was submerged into the blood Gu.

The bright red blood Gu started to move, leaving from the heart, following the tendons, and came out of Lu Chen's body.

A "pop" sound;

Then he saw the blood Gu appear in Lu Chen's palm, with a stream of blood.

However, it seemed to be very spiritual and quickly flew back into the underworld stone and landed in the hands of the red-haired old man.

Then, the old man looked at Lu Chen.

"Swish!"

Lu Chen checked his body and found no trace of blood poison, so he placed the Phoenix Blood Crystal and the bottle containing Liuyin True Water on the underworld stone.

"very good."

The red-haired old man nodded with satisfaction and collected the Phoenix Blood Crystal and Liuyin True Water.

Immediately afterwards, without hesitation, he poured the Liuyin True Water from the bottle and applied it on the top of the Hades Stone.

Then, the Phoenix Blood Crystal, the Dragon Blood Stone, and the Sun Essence Stone were suspended in the sky, and three kinds of magical light bloomed. There were also the sounds of phoenixes and dragons, and the breath was as hot as the blazing sun.

Seeing this, Lu Chen hurriedly withdrew his gaze, and then stepped back step by step.

Feng Shenyu was stunned when he saw this.

"Hey, little guy, you seem to be afraid of me?" the red-haired old man said with a smile.

"Junior just doesn't want to disturb senior's escape, so I'll take my leave." Lu Chenpi said with a smile, and then walked out of the cave.

Seeing this, Feng Shenyu didn't hesitate at all and hurriedly retreated.

"Disperse!"

The red-haired old man seemed to turn a blind eye to this, and suddenly raised his hands slightly, and saw that the three objects of the Sun Essence Stone were close to the part of the Ming Stone coated with Liuyin True Water.

Then, the Sun Essence Stone burst out with strong solar power, brilliant and hot, like the red sun, dispelling a large part of the strong Yin Qi on the Hades Stone.

Immediately afterwards, the phoenix blood crystal and dragon blood stone melted in a burst of popping sounds, and the phantoms of the phoenix and the real dragon flew up, exuding the powerful power of the phoenix and the power of the real dragon, and the high-pitched phoenix cries and dragon sounds.

The roaring sound resounded at this moment.

A terrifying force of Yin spread out.

However, it was soon weakened by the power of the Sun Essence Stone and slowly dissolved.

The part of the underworld stone that was coated with Liuyin True Water suddenly made a hissing sound, as if it was dissolving.

The power of the Sun Essence Stone shines on it, which is full of solar energy, and the power of Yin is completely dimmed.

"Buzz!"

After a few breaths, the red-haired old man rolled up his hands and burst out a terrifying force, integrating all the power of the Sun Essence Stone, Phoenix Blood Crystal, and Dragon Blood Stone into his palms, and directed towards those few people.

The nearly blurred part of the Hades Stone was photographed.

A "bang" sound;

The underworld stone made a loud noise and erupted with a surge of Yin Qi.

Immediately afterwards, that part of the underworld stone became void and cracks appeared.

Then, with a soft "puff" sound, that part of the underworld stone dissipated.

"Whoa!"

The red-haired old man moved and rushed out.

An extremely powerful force radiated from his body, and then he laughed loudly: "Hahaha, my chariot shaft has finally come out. Monsters and humans, you will tremble under the feet of my chariot shaft again."

"What a terrifying power."

Outside the cave, Feng Shenyu was one step behind. Feeling the power of the red-haired old man's chariot shaft, his face changed drastically and he immediately sped up.

"Ancestor, have you ever heard of the name Cheyuan?"

Lu Chen was already rushing out of Heigouyuan. When he heard the name Cheyuan, he hurriedly asked his ancestor Lu Jie.

"Cheshao? Ancestor, I have never heard of it, but looking at his posture, I'm afraid he is an extremely powerful being." Ancestor Lu Jie said.

"You two boys, stop here."

Suddenly, the sound of the red-haired old man driving the carriage suddenly came from the cave, very quickly, and filled with a chilling air.

The entire Black Dog Abyss was rumbling, as if a mountain was collapsing and the earth was cracking.

"The second level of the Mysterious Gate of Life and Death? No, the third level of the Mysterious Gate of Life and Death?"

Lu Chen's expression suddenly changed.

This chariot shaft is indeed powerful, and it is actually the third level of existence in the gateway to life and death.

I don't know if this is his peak cultivation level, otherwise, he was definitely more powerful than this originally.

Lu Chen is no match for such existences.

Therefore, he left in a hurry.
