The process of preparing the "Tianyue Blood Marrow" is extremely complicated, and Chen Yu dared not be distracted at all.

Once the formulation fails, even Chen Yu will feel heartbroken.

Therefore, he opened the cave formation and did not want to be disturbed.

Three days later.

Chen Yu threw the Moon Spirit Mine Mother and the Blood King Marrow into a large cauldron.

Boom!

With a wave of his hand, the [Blood Flame] surged out, entrenched under the cauldron, releasing the scorching high temperature.

"The last step is to melt the true fire and spirit flames forty-nine days!"

Chen Yu covered the ancient tripod.

[Blood Flame] There is a flame spirit, let it melt itself and then do it.

Chen Yu came aside, ran the "Secret Textures of the Demons" and began to go into seclusion and practice.

He found that if he majored in the secret magic body, his progress was as normal, but the speed of his practice was slowed down a lot.

"It seems that as the realm improves, the "Demon Secret Textures" is somewhat powerless."

In fact, when you reach the late stage of the Kūkai Realm, your cultivation progress will slow down, and it will be extremely difficult to advance every time.

If there are better practice techniques, this shortcoming can be slightly made up for.

Chen Yu does have a better choice at present, that is, "Six Yuan Gui Tian Gong", which is a powerful technique left by Emperor Xuanming. Even in the Blood Sea Realm, it is difficult to find a technique that exceeds "Six Yuan Gui Tian Gong" in the blood sea realm.

However, Chen Yu practiced the "Secret Textures of the Heavenly Demons" that combines the Demonic Way and the Body Way.

If the "Six Yuans Return to Heaven" is directly modified, it will definitely not be perfectly compatible with the Taoist practices in "The Secret Text of the Demon".

In other words, Chen Yu's revision of "Six Yuans Returning to Heaven" will make his cultivation progress better, but his cultivation will be difficult.

It is precisely because of this that Chen Yu did not immediately modify the exercises.

Just as Chen Yu was thinking, a shout came from outside the cave.

"Yu Shaozu, I am Zheng Xiujing..."

"What did that woman ask me for?"

Chen Yu felt inexplicably and ignored him.

It takes forty-nine days for the Tianyue Blood Marrow to succeed. He doesn't want such treasures to be known to others.

Outside the cave.

Zheng Xiujing shouted a few times, and there was no change in the barrier outside Chen Yu's cave.

"In the past, no man dared to ignore me like this."

Zheng Xiujing said lightly.

In the past, there were all other blood men who rushed to visit her, but she was the only one who refused others' share.

But Zheng Xiujing was not very unhappy about Chen Yu's ignorance, but instead smiled: "He is so unique."

Without staying for a long time, Zheng Xiujing left quickly.

But next, she would come here every few days.

Inside the cave, Chen Yu was speechless.

"Did this woman suffer a loss in my hands and still hold a grudge?"

Chen Yu felt that this woman was too jealous and too vengeful.

However, he is now the young ancestor, and no one dares to break into the cave, even if he is in seclusion for several years, he will not go out.

Moreover, he was not afraid of this woman. If it weren't for the other party's father, the king of the blood clan, Chen Yu wouldn't have spared Zheng Xiujing easily when he was in the blood cellar.

"Five days left!"

Chen Yu looked at the ancient tripod in the center of the hall with anticipation.

Tianyue Blood Marrow is a recipe that King Chiyan got from some unknown place.

This blood marrow has an amazing effect. It can not only improve physical fitness and promote the level of life, but its main effect is to greatly improve the qualifications of spirits.

It is also explained later that if the material quality is excellent, or the user's own qualifications are special, the Tianyue Blood Marrow will produce other special effects.

Chen Yu's spiritual qualifications have reached the level of a top-grade spiritual body. If they are greatly improved, their cultivation qualifications will be enough to be among the geniuses in the Dayu Realm.

In the early stage of the path of cultivation, those with poor spiritual qualifications may be able to catch up with good qualifications through opportunities and efforts.

But in the later stage, the gap will become bigger and bigger.

Even if Chen Yu has many opportunities, if his cultivation qualifications are not raised, he will probably not have the achievements at this moment.

"Master, time is up."

Five days later, Yan Ling shouted, and the flames under the cauldron suddenly weakened.

On the 19th, it was working day and night, and it was so tired that it was finally relieved.

However, at the same time, Yan Ling is also very looking forward to the "Tianyue Blood Marrow".

Chen Yu waved his palm and opened the cover of the tripod.

In the ancient tripod, a ball of silver-red liquid floated, emitting a strange fragrance.

Even the Yan Ling of [Blood Blade] had a trembling mind at this moment, and a desire appeared in her heart.

"Master, take this treasure quickly, otherwise it will definitely attract the attention of others."

Yan Ling immediately said.

It had surrendered to Chen Yu, but it still developed a greed just now.

The blood marrow of the heavenly moon is to some extent considered a blood treasure.

This is the territory of the blood clan, and there are no other blood clan powers that can smell the smell.

"good!"

At this moment, Chen Yu felt the preciousness of the blood marrow of the moon.

It is no exaggeration to say that its effectiveness is equivalent to participating in a food banquet. Of course, it is definitely not as good as the opportunity for a top-class seat, and at most it can only be considered an opportunity for a middle-class seat.

But this is also very amazing.

Chen Yu opened his mouth and sucked it, and the silver-red liquid entered his mouth.

The moment he swallowed it down, Chen Yu felt that the blood marrow of Tianyue seemed to be integrated into himself, and he could not detect its existence at all, and could only feel the transformation of his body.

Chen Yu felt that the flesh, bones, and internal organs in his body were washed and purified.

He sat down quietly and felt the magical effect of the blood marrow of the moon.

Chen Yu felt that every cell in his body seemed to be cheering and excited.

He immediately used the martial arts to practice the secret pattern demon body, and found that the progress speed was far beyond ordinary times.

at the same time.

Outside the cave.

"Huh? What did that smell just now? It's so fragrant and charming."

Zheng Xiujing opened her eyes.

As a blood brewer, she is extremely sensitive to the taste of blood and judges that the blood fragrance comes from Chen Yu's cave.

"Are you refining blood brew? There is such an attractive fragrance. He is so... mysterious!"

Zheng Xiujing's eyes showed an obsession.

A cave not far from Chen Yu's cave.

Whoosh!

A blood-colored skull appeared silently at the top of the palace, and the whole world seemed to be solidified, extremely quiet.

"What was that breath just now? It actually made the blood in my body burn."

He whispered, jumped out and disappeared into the moonlight.

...

One day later.

Chen Yu's physical aura was getting stronger and stronger, and the secret magic body was progressing by a huge amount.

His life level is very close to the peak level of the late stage of the Kūkai Realm.

In this case, the subsequent practice of the secret pattern demon body will be more smooth.

Chen Yu felt that the efficacy of Tianyue Blood Marrow had almost been absorbed.

He was very much looking forward to how much his spiritual qualifications had improved.
