The lights in Yinliu City were brilliant, and the entire city was shrouded in warm light. No one knew that at this moment, a determined figure was walking step by step towards the mountains behind the city.

Xue Kong climbed over a hill and saw an even more open valley in front of him. The environment here was quiet and the climate was pleasant. It was the burial place of the ancestors of the Xue family. After several twists and turns, he finally stopped in front of a luxurious tomb.

There is a gravel path under my feet. Unlike other tombs, there are no weeds on this tomb and the surroundings are clean. There are fresh fruits and vegetables as offerings and half-burned bamboo incense in front of the tomb, with the fragrance curling up.

The light and shadow of the two candles swayed in the hot wind.

Even in June, there were gusts of cold wind on the hilltop full of graves, giving off an eerie feeling.

Xue Kong glanced at the offerings and bamboo incense. He knew that the tribesmen had just come to worship today. Perhaps because the Dharma Assembly was coming in two days, they didn't have time to come to worship every day, so they simply provided two days' worth of offerings at once.

"Great-grandfather, Kong'er is here to visit you." Xue Kong spoke softly, with a hint of melancholy in his voice.

After he finished speaking, he put down the things he brought, then turned around, searched in the mountains and forests for a while, brought a huge stone, placed it in front of his great-grandfather's grave, then knelt on his knees and worshiped in front of the stone.

His eyes were determined and he knocked his forehead hard against the stone.

Bang.

His forehead was broken and blood was flowing.

"Kong'er came here for no other reason than to borrow my great-grandfather's bloodline."

Bang!

There was another muffled sound, and Xue Kong's forehead hit the stone again. The wound tore open and more blood flowed out, and the stone became bloodstained.

Xue Kong seemed to feel no pain. He simply stared at his great-grandfather's tombstone and spoke again, "Kong'er has an immortal body. If he doesn't embark on the path of cultivation as soon as possible, disaster will befall him sooner or later. I have found a way to open the spiritual sea and absorb the spiritual energy of heaven and earth, but afterward, I urgently need a pill to stabilize and improve my cultivation. I have also found this pill."

Bang! Bang! Bang!

Xue Kong kowtowed three times on the stone. He kowtowed without holding back and with great force. After three kowtows, blood and flesh burst from his forehead, and he felt dizzy and almost fainted.

In the dim candlelight, a trace of rotten flesh from Xue Kong's forehead was stuck to the bloodstained surface of the stone.

Blood from his forehead slid down the corners of his eyes, as if Xue Kong was shedding tears of blood.

"Great-grandfather, in the future I will bathe in the long river of time and spend my years with the sky. The Xue family bloodline will never be cut off."

After knocking his head against the stone for the last time, Xue Kong stood up again. His face was covered in blood, his appearance was hideous, his steps were unsteady, and he was a little unsteady.

After taking a deep breath, a quarter of an hour later, Xue Kong threw the big stone into the forest. Then he picked up the hoe he had brought with him and walked towards his great-grandfather's grave. He walked around to the back of the grave and raised the hoe high...

He actually planned to dig up his great-grandfather's grave with a hoe.

Xue Kong did such a perverse act tonight, but he did not feel too much inside. The few kowtows and the broken forehead showed his apology.

Besides, compared to what was about to be done, these were nothing.

An hour later, Xue Kong finally dug up his great-grandfather's tomb completely. The soil flew up, revealing a crimson coffin in the tomb. Because it had been buried for a long time, the coffin had long lost its former luster and hardness.

"Great-grandfather, Kong'er apologizes." As soon as he finished speaking, Xue Kong raised the hoe high in the air again and smashed it hard on the crimson coffin.

Bang!

Bang bang bang!

Again and again, Xue Kong was tireless and kept hitting the same spot on the coffin with his hoe.

After dozens of times, Xue Kong finally smashed the coffin open by one third.

Inside the coffin was a skeleton, along with gold and silver ornaments buried with it. The luxurious sky-blue robe on the skeleton had long since faded. This was Xue Kong's great-grandfather, the person with the highest cultivation level in the Xue family.

Later, they died in a fight, and the Xue family's status in Yinliu City plummeted. It was not until the appearance of Xue Kong's father that they regained their glory.

Xue Kong turned over and entered the coffin. A fishy smell immediately hit him in the face. It was the smell of a rotting corpse. He suddenly felt dizzy and the world was spinning. But he was still cautious and tiptoed, for fear of being disrespectful and stepping on his great-grandfather's bones.

He took out a tinder from his sleeve and blew it into flames.

The faint firelight illuminated everything inside the coffin. Xue Kong did not even take a second look at the buried gold and silver. His gaze was all fixed on his great-grandfather's bones, especially on his left sternum, which he examined carefully for a long time.

"The heart bone is intact, and the power of the blood has not dissipated." Xue Kong took out a dagger, aimed at the heart bone of the corpse, and stabbed it hard.

All I heard was a click.

A small piece of heart bone was cut off by Xue Kong.

Picking up the heart bone, Xue Kong's eyes showed a rare joy: "My great-grandfather was once a cultivator. His bloodline power was pure and contained immense spiritual power. When he died in battle, he used his cultivation to condense all his bloodline into his heart bone. If I hadn't encountered this in my previous life, I would never have known this."

"Just the blood within this heart bone is enough to rival a Qingling Pill, allowing the Xue family's descendants to advance from the first level of Qi Condensation to the third level. This is something only the clan leader knows about. I'll take it away tonight, just in time to prepare for improving my cultivation and preparing the blood refining formation in a few days."

During the hundred years when Xue Kong was treated as a medicine man by the fairy lady of the Three Immortals Sect, he was not imprisoned in the Three Immortals Sect all the time. Perhaps because she felt more at ease having him by her side, the fairy lady would take Xue Kong with her every time she left the sect.

By chance, Xue Kong saw a magic formation, which he kept in mind. Now, by chance, he has returned to his youth. Xue Kong plans to use this magic formation as the cornerstone for reopening his spiritual sea.

"I'm missing important materials, so I can't create a complete formation. However, I can make do with other materials as a substitute and create a small formation... the Blood Refining Formation."

Putting away his heart bones, Xue Kong lowered his head and glanced at his great-grandfather's corpse.

Even though it is a corpse, because the cultivator used his cultivation to condense his bloodline before death, this corpse is also a low-level treasure. However, ordinary cultivators cannot use its special features.

Xue Kong had a hundred years of experience in cultivation. Looking at the bones, he pondered, "The materials for the blood refining formation, in addition to the power of blood, also require ashes, the skin or hair of close relatives, and wood-attributed materials that have been aged for a hundred years. Finally, add ghost energy or death energy, and add rich spiritual power to stimulate it, and it can take shape."

"I can't get other materials right now, but these ashes and hair are right before my eyes."

Taking out a dagger, Xue Kong cut off three fingers of the corpse, then went to the corpse's head, cut off some of the messy hair that had not yet completely rotted, and stuffed it all into his arms.

After doing all this, Xue Kong made sure that nothing was left out, then he left the coffin and refilled the grave. As the sun rose, he bowed deeply to his great-grandfather's grave and turned to leave.
