"According to the written record on this secret door, you now have the power to push open one of the doors and obtain the things left by one of the Four Holy Beasts! This is the Four Holy Beasts of the Ancient Period, they are very powerful existences!" The tower keeper then became extremely solemn in his voice: "However, if you can really inherit the things left by the Four Holy Beasts, you must agree to one condition!"

"Condition, with the current situation, the four holy beasts should have returned to their spirits, what do you need to promise them?" Yu Yichen was a little puzzled in his heart. Pen Fun Pavilion wWw. ｂiquge。 ｉｎfo

"I guess it's not the Four Holy Beasts who wrote this, but someone else!" the tower keeper said lightly, but at this time he had already exhausted his strength, and he disappeared without saying a word.

"Hey, hey!" Yu Yichen didn't have time to shout! As the saying goes, there is an old man in the family, if there is a treasure! But this time, your old man will explain things clearly before sleeping.

The tower keeper didn't hear back, and Yu Yichen had no choice but to rely on himself! After turning around the secret doors left by the four holy beasts, he began to guess what was left inside.

The Green Dragon, the Vermilion Bird, the White Tiger, and the Xuanwu! The things left behind by these four holy beasts Yu Yichen were very curious, and he also wanted to be able to have them all.

But it's obviously impossible! It's already very difficult to withstand the power of one holy beast, and it's like looking for death to endure four.

"Among the four holy beasts, Xuanwu's defense is the strongest, and the physical body is stronger!And my biggest problem now is that my physical body can't keep up with the progress of the divine soul at all!, therefore, it should be more in line with my situation to choose Xuanwu!" Yu Yichen groaned slightly, and it seemed that there was no other choice.

The talent gushed out, the door of the Xuanwu dark room was pushed open, and Yu Yichen strode in. The strong smell of blood in the air came through, but it was not pungent at all, on the contrary, it had a sweet feeling.

"This, what is this?" Yu Yichen was stunned for a moment, because in front of him was a huge pool, and what flowed in it was a red liquid with a pale gold.

There was still a divine aura above the pool, but Yu Yichen instinctively sensed a danger.

The tower keeper said before that the four holy beasts had left a certain part of their bodies in the dark room, so could it be the blood of Xuanwu flowing in the blood pool in front of them?

"This is more powerful than the blood of any fierce beast, containing countless energies!" Yu Yichen's heart beat wildly, his original plan was to enter the Yan family's secret realm to kill the fierce beast and bleed and draw bones to refine his immortal law body. But right now, with the blood of Xuanwu, the effect is better than that of hundreds of thousands of ordinary fierce beasts combined.

"Just relying on the immortal law body, I don't know if I can transform and absorb the terrifying energy contained in the Xuanwu blood in time!" Yu Yichen quickly calmed down, sat down cross-legged in the blood pool, and began to deduce with the Dao Seed.

The Dao Seed is the most precious thing that the Martial Saint left to Yu Yichen, and it is said that nothing can be pushed, as long as there are enough spirit stones and star stones, everything is possible.

And the original Yu Yichen lacked sufficient resources and wealth, so he had to pick his pocket every time to accurately calculate and deduce! But now it is different, he is rich and capricious, and he can naturally give full play to the role of the Dao Species.

Three hours later, Yu Yichen woke up in a cold sweat, shook his head and smiled bitterly! The powder of the star stones around him has accumulated a lot! The level of this Xuanwu blood is too high, and the star stones consumed by deduction are simply as worthless as the lower grade spirit stones.

"If you want to directly enter here to cultivate the immortal law body, it is undoubtedly tantamount to asking for your own death!" Yu Yichen got up, forcibly resisted and immediately jumped into the blood of Xuanwu to cultivate to the impulse, and went out of the dark room first.

In order to cultivate the immortal dharma body in the blood of Xuanwu, he needed to refine at least hundreds of auxiliary pills.

Three days later, Yu Yichen swallowed nine flesh protection pills in one go and jumped into the pool of blood.

"Boom!" It was less than a breath of time, and all the blood, meridians, and bones in his body let out a mournful sound, as if the lowly commoner could only kneel and tremble when he saw the king. And the aggressiveness of Xuanwu's blood was extremely strong, and it quickly seeped into several drops into Yu Yichen's body.

Yu Yichen hurriedly transported the immortal law body, the blood of Xuanwu was too domineering, and he directly began to dissolve the meridians and bones in his body!

However, fortunately, at this time, the nine kinds of pills played a huge role, and the meridians of the bones that had just been dissolved quickly began to rebuild with this Xuanwu blood.

"Ahh

But once the immortal dharma body is in operation, the divine soul must definitely remain awake, even if you want to hit yourself headlong at this time, you have to endure it.

"Ten, nine, eight......" Yu Yichen was silently calculating in his heart, and just when the medicinal power of the nine pills was about to be exhausted and the immortal law body was also operating to the limit, he suddenly jumped out of the blood pool.

His whole body was flushed, and the blood of Xuanwu had already melted into his body, and not a drop had slipped down.

"It's less than a hundred breaths of time, this Xuanwu blood is really too domineering!" Yu Yichen took a deep breath, if he slowed down, he might hang up.

Of course, this is also normal, with his current level of immortal Dharma Body, he is not even at the level of a martial artist, so he naturally can't resist for long! But being able to succeed for the first time means that the direction of Dao seed derivation is not wrong.

He rushed to the alchemy room and began refining the pill he needed next time!

The Xuanwu blood in the blood pool didn't consume much at all at first, but as he jumped in again and again, the amount of Xuanwu blood consumed began to double.

Once Yu Yichen finished refining the pill, he rushed straight to the blood pool, and after the blood pool climbed up, he immediately rushed to the alchemy room.

And the abundant energy contained in the blood of Xuanwu made him full of infinite physical strength even if he didn't eat or sleep.

Unknowingly, Yu Yichen had been in this Beast Emperor Cave Mansion for three months, and his cultivation in the Immortal Law Body had also reached an extremely high level.

Half of the Xuanwu blood in the blood pool had been consumed, and even Yu Yichen himself felt as if he was in a dream!

"It seems that someone is always secretly peeping at me!Could it be the will of the world? This feeling appeared a month ago, and now that the physical body is getting stronger and stronger, it becomes clearer!" Yu Yichen thought as he climbed up from the pool of blood and walked outside.
