This bone formation incorporated the Five Elements and Eight Trigrams. If it were anyone else, it would likely take half a year to break through even a tenth of it.

However, Zhang Jingmo only took four days to lead Lu Guijiu through this bone formation.

Inside the formation, the yin winds howled furiously. From time to time, various sounds of laughter, anger and scolding could be heard, making it even more eerie in this vast cave.

Zhang Jingmo had passed through this formation many times, which was why he could be so efficient. He had thoroughly studied this formation, so every step he took was a shortcut to leave it.

Lu Guijiu was held in Zhang Jingmo's arms, protected by spiritual energy, and was not harmed in the slightest by the formation.

Unlike when walking the small path earlier, Lu Guijiu was very calm when passing through this bone formation. He would occasionally look up at the countless skulls hanging from the dome above.

Lu Guijiu said, "Master, how many people are there here?"

Zhang Jingmo replied, "Thousands upon thousands, too many to count."

Lu Guijiu asked, "Then how did they turn into a formation?"

Zhang Jingmo said, "When you have attained great power, the people of the world will be like ants to you. Wouldn't it be easy to catch a nest of ants?"

Upon hearing this, Lu Guijiu showed a pensive expression. He lowered his head to look at Zhang Jingmo's feet and saw a light blue glow beneath his master's feet. With each step, the cry of a child could be heard.

As Zhang Jingmo got closer to that key point, the child's cries became louder and louder.

The bones kept colliding and falling beside Zhang Jingmo, some even grazing the tip of his nose before falling to the ground, surrounding him with a foul stench. If it were someone with a weak mind at this moment, they would likely be affected quickly, misstep, and end up in an inescapable place.

For Zhang Jingmo, the bone formation was a piece of cake.

The moment he stepped onto the opposite shore, the child's cries reached a piercing peak, as if wailing blood, deafeningly loud. However, after a short while, this crying turned into cheerful laughter. The laughter continued for a few moments, then slowly faded away...

Zhang Jingmo reached the other side of the bone formation and began to prepare for the final matter.

Zhang Jingmo had Lu Guijiu sit down, then used his own spiritual energy to cultivate Lu Guijiu to the best state. Lu Guijiu still didn't know what was going to happen. He just obediently sat cross-legged on the ground, allowing his master's spiritual energy to enter his body, bringing a sense of comfort.

Zhang Jingmo spent a few days nurturing Lu Guijiu's body, then gave him a pill to swallow.

After swallowing the pill, Lu Guijiu quickly felt a sense of ease all over his body, as if the spiritual energy inside had been refined again.

Zhang Jingmo said, "Guijiu, do you know why I brought you here?"

Lu Guijiu shook his head. He originally thought Zhang Jingmo brought him to the Dark Cavern to train his physique by slaying evil spirits, but he quickly discovered that since entering the cave, Zhang Jingmo had been protecting him the whole time and didn't let him take action himself at all.

Zhang Jingmo said, "In this Dark Cavern, there is a book."

Lu Guijiu was stunned. "A book?"

Zhang Jingmo said, "It's called the 'Blood Hell Heaven Scripture', and it's the most suitable cultivation method for those with the Ten Absolute Spiritual Roots."

Lu Guijiu was confused, but grasped a key point. He said, "Master, I have the Ten Absolute Spiritual Roots?"

Zhang Jingmo nodded. He had never specifically told Lu Guijiu about this before because he felt it was completely unnecessary.

Lu Guijiu had seen this unique physique in books before. The Ten Absolute Spiritual Roots, the ten paths of the absolute, referred to people with this kind of spiritual root. Although they progressed rapidly in the early stages, it was very difficult to find a suitable cultivation method. As a result, most could only stay in the Qi Refining stage until their lifespan was exhausted and they perished.

Lu Guijiu never imagined that he would also have this kind of physique.

Seeing the shock in Lu Guijiu's eyes, Zhang Jingmo had no intention of comforting him. He slightly raised his hand and pointed to the obscured darkness ahead, softly saying, "Take a look."

Lu Guijiu looked up and only saw endless darkness. He thought for a moment, then wrapped spiritual energy around his eyes. Taking a closer look, he gasped.

He saw countless blood-red vines cascading down from the sky on the cliff hidden in darkness. These vines were covered in red thorns, clearly not something to be trifled with.

After observing for a while, Lu Guijiu discovered that the vines were actually slowly squirming, obviously not ordinary plants.

Zhang Jingmo said, "The 'Blood Hell Heaven Scripture' I want you to find is at the end of these blood vines." He pointed to the unclear heights above and said softly, "Go get it yourself."

Lu Guijiu pressed his lips together and looked up at the endless blood vines on the wall.

Zhang Jingmo asked, "Well?"

Lu Guijiu clenched his fists, then nodded and uttered a word: "Okay."

Although called vines, the blood vines were not plants, but a kind of yin evil creature that liked to grow in the dark. They enjoyed fresh blood and living in groups. If picked and soaked in a special medicinal liquid, they could be made into very tough ropes.

Facing the dense blood vines before him, the eleven-year-old Lu Guijiu clenched his fists but did not retreat a single step.

Zhang Jingmo sat down on the ground, closed his eyes and began to meditate, looking as if he no longer cared about how Lu Guijiu would fare.

Lu Guijiu first reached out and touched the blood vines. With a living being approaching, the blood vines were extraordinarily excited. Lu Guijiu was caught off guard and was pricked by the blood vines, creating a small wound. The spiritual energy contained in the blood flowing from the wound and the fishy smell it emitted agitated these vines.

Lu Guijiu looked down at the wound on his hand, lost in thought. He did not act rashly, but carefully considered what method he should use to reach the top of the blood vines.

Lu Guijiu was not in a hurry, and naturally, neither was Zhang Jingmo. In fact, he was also curious about what method Lu Guijiu would use to reach the top of the blood vines - according to Zhang Jingmo's logic, if the Lu Guijiu of the past could do it, the current Lu Guijiu should be able to as well.

Time passed quickly, and soon three days had gone by. There was still no movement on Lu Guijiu's side. Just as Zhang Jingmo thought he would have to wait a few more days, Lu Guijiu made his move.

Zhang Jingmo opened his eyes and saw Lu Guijiu in mid-air.

Lu Guijiu held a flying sword in his hand and stood on a stone slab about ten feet in size. Below the stone slab, Lu Guijiu used his spiritual energy to form a tubular restriction, allowing the vines to only go from top to bottom, constantly being lured by the blood at the bottom of the stone slab, pushing the stone slab up inch by inch.

If any other blood vines tried to attack Lu Guijiu, they would be cut off one by one by his flying sword.

Lu Guijiu had practiced swordsmanship with Bai Lingxiao for five years. Although he had not fully mastered the true teachings, he had gained some skill.

As more and more blood vines swarmed over, Lu Guijiu rose higher and higher. Zhang Jingmo watched him disappear into the darkness - this was something Zhang Jingmo could not obtain.

Luck and opportunity, on the path of cultivation, Zhang Jingmo had tried his best, but could not win the favor of the heavens.

It was indeed possible to smear blood on the stone slab below to attract the blood vines, but whether the stone slab could withstand the entanglement of the blood vines, and whether the stone slab would suddenly overturn when it rose into the air, these things were unknown.

If throwing dice was used as a metaphor for dealing with this opportunity, Zhang Jingmo could only gamble like a normal person, while Lu Guijiu could throw a winning roll without any concern.

So even if Zhang Jingmo saw how Lu Guijiu handled this matter, he could not learn from it. He sighed, thinking that he had not given up after all, wanting to see if there was anything to learn from the path Lu Guijiu took, but in the end, it only made him sigh, and he could not even feel a bit of envy.

Thinking about these things, Zhang Jingmo felt more and more uninterested. He simply sat down on the spot and continued to meditate.

As for Lu Guijiu reaching the top of the blood vines, it was not as easy as Zhang Jingmo thought.

The stone slab under his feet, originally ten feet wide, could now barely be stepped on, with other parts being crushed by the blood vines. Lu Guijiu had to speed up the killing of the blood vines.

In the blood vines, one could not fly, otherwise one would be directly rolled up by the blood vines and dragged into the sea of vines, eventually exhausting one's spiritual energy and unable to escape.

Lu Guijiu had already read about these in the book, so he did not suffer any losses in this matter. However, if he did not reach the top, Lu Guijiu was afraid that he would have to use his spiritual energy to fly up.

The blood vines pushed the stone slab up another section, and just as it was about to shatter, Lu Guijiu finally saw the end of the blood vines - he saw a face.

A closed-eyed, strangely featured Giant Face.
