I picked up skill fragments in the demon world.

Chapter 400 Blood-Transforming Divine Sword
The Nine-Bend Yellow River Formation was like a thorn stuck in the throat of the Patriarch of Longevity, making him unable to sleep or eat.

Qingcheng Mountain is his own territory, and suddenly a huge formation of unknown depth appears. What is going on?

As for the whereabouts of the ancestors, he has already been alert in his mind to avoid being ambushed.

Zhang Chen did not leave after hearing the instructions from the Grandmaster Changsheng. Instead, he lowered his head and said, "I have recently gained some insights into the scriptures. I would like to go into seclusion for a period of time to see if I can cultivate magical powers. I ask for Grandmaster's permission."

Upon hearing this, the Changsheng Patriarch nodded and said, "Go ahead! If you can cultivate magical powers, it will be your good fortune."

Although he said so, he didn't think in his heart that Zhang Chen had the qualifications to cultivate magical powers.

Zhang Chen glanced at the Patriarch of Longevity, then retreated respectfully. He wanted to practice the Blood-Transforming Divine Sword, so he had to go into seclusion for a while.

Zhang Chen walked all the way back to his own yard, thinking about his retreat. He didn't know if his practice of the Blood-Transforming Divine Sword would cause any disturbances. His aura would be captured by the Patriarch of Longevity, which would cause some unexpected changes. So he needed to think of a way to cover it up.

Zhang Chen thought for a moment and made up his mind. He planned to go to the Nine-Bend Yellow River Formation to practice the Blood-Transforming Divine Sword. With the Nine-Bend Yellow River Formation as a cover, he was not afraid that the aura revealed by the Blood-Transforming Divine Sword would be sensed by people outside.

I happen to have the art of teleportation of water drops. I can leave a drop in the room in advance. If the master comes to check, I can quickly perform the teleportation technique to return to the room.

And since I live in the backyard, as long as I inform Xu Erniu in advance, no one will disturb me.

Who would care about a little disciple who can't even cultivate magical powers?

The straight-line distance between his house and the Nine-Bend Yellow River Formation was less than 800 meters. It was just the right distance, simply perfect.

Zhang Chen walked all the way to Xu Erniu's house and smelled a herbal fragrance from afar coming out of the house and floating in the small courtyard.

"My little sister, are you practicing alchemy?" Zhang Chen asked softly while standing outside the house.

As soon as he finished speaking, the door opened and Xu Erniu walked out of the house, her hair dishevelled and her face dirty. She asked, "How come you have time to come to see me today?"

"I'm going to go into seclusion for a while and try to cultivate some magical powers." Zhang Chen said.

Xu Erniu's eyes lit up when she heard this, and she quickly stepped forward and asked, "Have you realized anything?"

"I have a little bit of it, but I don't know if it will work." Zhang Chen said.

"It will definitely work!" Xu Erniu corrected Zhang Chen's words with certainty.

Zhang Chen smiled upon hearing this, with a gentle look in his eyes. He patted Xu Erniu's head and said, "You have to take good care of yourself. I'm going to be in seclusion for a while, so I'm afraid I can't take care of you anymore."

"Just go ahead. I'm not a child. Cultivating magical power is the most important thing." Xu Erniu urged nonchalantly, "Go quickly! Don't waste time and let the inspiration slip away."

Zhang Chen smiled and nodded. After parting with Xu Erniu, he came to his own house. After closing the doors and windows, he turned into a stream and escaped into the Nine-Bend Yellow River Formation. He created a sheltered place in the Nine-Bend Yellow River Formation and began to silently use his magical powers to comprehend the secret of the Blood-Transforming Divine Sword.

Zhang Chen is the master of the way of blood. The secret of the Blood-Transforming Divine Sword is not difficult for him. He has understood all the mysteries at a glance. Then Zhang Chen poured out all the eighteen kinds of blood he had collected, and saw eighteen balls of glittering blood of different colors suspended in front of him. Then the blood control technique circulated in Zhang Chen's body, and wisps of Qi continued to drill out of the eighteen balls of blood, poured into Zhang Chen's mouth and nose, and entered Zhang Chen's Xuanguan acupoint. Then Zhang Chen's blood way power circulated, evolving countless runes that gathered in the Xuanguan acupoint in his body, and gathered together with the eighteen kinds of blood. The two sides formed an inexplicable reaction, and saw the runes constantly merging into the blood, and soon a blood ball the size of a fist was formed. There were runes combined and intertwined in the blood ball, turning into chains of order, and those chains of order were intertwined according to some mysterious law.

Time passed day by day, and no one came to disturb Zhang Chen. The master paid no attention to Zhang Chen at all. Except for Xu Erniu who would occasionally come and stand outside Zhang Chen's door for a while, no one else paid attention to this little unknown person.

Time passed quickly, and in the blink of an eye, it was forty-nine days.

In the Nine-bend Yellow River formation, there was a sudden sound of ghosts crying and wolves howling. A drizzle of blood-red rain fell in the endless yellow sand, and the yellow sand in the sky was dyed blood-red. In front of Zhang Chen, all the blood was absorbed. At this time, Zhang Chen was seen sitting cross-legged in the yellow sand, with red light flowing around him. In his mysterious gate, there was a fist-sized ball of blood squirming and twisting, as if it could breathe, constantly breathing and absorbing the spiritual energy in the dark.

Within that fist-sized ball of blood, there were hundreds of chains composed of rune orders that constantly intertwined and connected, forming an inexplicable rune formation. The rune formation was very mysterious, and even Zhang Chen, the ancestor of the Blood Path, found it difficult to discern the mystery. It felt as if the rune formation was formed naturally, a natural rune formation.

As Zhang Chen's mind moved, the ball of blood flew up, shuttled through the meridians of the body, fell into the crystal core, and fell into the boundless sea of ​​blood. After the ball of blood absorbed the blood of the sea of ​​blood, it began to pull and shape, turning into a long sword as thin as a cicada's wing, flashing blood-red light.

The long sword is somewhat similar to the Mo Dao, the entire blade is as thin as a cicada's wing, and it is engraved with blood-red lotus flowers. The handle is silvery white, like a piece of calcified bone, like mutton-fat jade, and has begun to be covered with patina. There is a small skull as decoration at one end of the handle. The skull is the size of an egg, and its eyes are flashing with green ghost lights, which looks very eye-catching.

The whole knife is one meter and five meters long, delicate and beautiful, without any evil feeling. No one would have thought that this knife is the epitome of bloody killing power. Once the body is stabbed by the long knife, the person will bleed profusely, and then the long knife will take away the essence of the blood and become the nourishment of the long knife.

“The next step is to keep killing living creatures and use their blood for nourishment. The more living creatures you kill, the more types of blood you will gather, and the more powerful the Blood-Transforming Divine Sword will become.” Zhang Chen stroked the Blood-Transforming Divine Sword with a hint of joy in his eyes.

The appearance of the Blood-Transforming Divine Sword made up for one of his shortcomings. He could practice martial arts and hone his own martial arts, thus eliminating one of his biggest shortcomings.

As Zhang Chen put away the Blood-Transforming Divine Sword, the vision of the divine sword's emergence disappeared. Zhang Chen stood up and walked through the yellow sand to the place where Monk Haichan was practicing. He saw that Monk Haichan was surrounded by five-colored divine light and fell into a state of deep nirvana refining.

"At least ten years!" Zhang Chen sighed softly. How many more decades can one waste in life?

Zhang Chen decided to come out of retreat. He had been practicing for such a long time, and it was time to come out. For him, the most important thing was to monitor the actions of the Changsheng Patriarch at all times. He didn't know if his theft of the Heaven and Earth Treasure Mirror would have a big impact on Xu Erniu.

He actually hoped that because of the loss of the Treasure Mirror of Heaven and Earth, Master Changsheng would give up his plan for Xu Erniu. Even if he no longer paid attention to Xu Erniu in the future and treated her as an ordinary disciple, it would be fine?

Zhang Chen used his escape technique to return to his house. He looked at the dusty house, then pushed open the door and walked out. He saw Xu Erniu sitting under a banana tree outside the yard in a daze. After hearing the sound of the door being opened, Xu Erniu opened her eyes and turned around abruptly. Her eyes were full of expectation as she looked at Zhang Chen: "Zhang Chen, are you out of retreat? Have you cultivated your Qi sense?"

She didn't dare to ask Zhang Chen whether he had cultivated magic power or not, she only dared to ask Zhang Chen whether he had cultivated the sense of qi. She knew that Zhang Chen's aptitude was too poor. Being able to cultivate the sense of qi was already a big step forward and gave him the opportunity to cultivate magic power.

Facing the concerned eyes of the little girl, Zhang Chen felt warm in his heart. It was worth it for him to plan for her. This girl has a conscience.

"Of course I have cultivated the sense of Qi. After all, such a long period of seclusion was not wasted." Zhang Chen met the nervous gaze of the little girl and said lightly.

Xu Erniu cheered and jumped up when she heard that. "Zhang Chen, you are awesome. I knew you could do it! You have cultivated your magic power today, so we should celebrate. Let's get drunk."

Zhang Chen didn't want to attract attention. He thought it was better to keep a low profile under the eyes of the Grandmaster of Immortality. So he patted the little girl's head and held her down: "Keep a low profile! Keep a low profile! We can just have a good meal in secret. Why bother disturbing all the brothers?"

The girl listened to Zhang Chen's advice and agreed with him, so the two brothers began to prepare meals with great interest and had a drink under the moonlight.

Zhang Chen looked at Xu Erniu and asked, "Have you made any progress in your practice recently?"

"It's not that easy. But I have mastered a new method recently." Xu Erniu put down her wine glass and casually broke off a piece of weed beside her. She held the weed in her hand, and green light flowed in her palm. Then the weed flashed with a bright light, and then it took root and sprouted, turning into a complete living plant.

Zhang Chen was surprised when he saw this and praised: "What a good trick! It's really a good trick!"

"What is this?" Xu Erniu put the plant on the ground and pointed her tender little white hand at the plant. The plant began to grow rapidly, then bloomed and bore fruit, and finally turned into a seed and fell to the ground.

In just three breaths, the plant had completed its life, leaving only a seed.

"Zhang Chen, we don't have to worry about eating fruits in the future. Just tell me what kind of fruit you want to eat. Even if we don't make much progress in cultivating immortals in the future, it wouldn't be bad to go home and sell fruits." Xu Erniu said proudly.
