Yun Lintian frowned upon hearing this. He didn't track their progress during this period and was oblivious to this. He asked. "What happened?"

Yun Qingrou was the one who explained. "The profound arts that we are practicing need a lot of soul power to form the spirit. For example, the Goddess of the Nine Heavens has to form nine spirits. The resource we have are not enough to help them from the spirit."

Yun Lintian immediately understood the problem. In short, everyone required a lot of resources to aid in forming the spirit. To his knowledge, there weren't many treasures that could increase the practitioner's soul power, and all of them were extremely rare.

He rubbed his temples and leaned on the sofa. Everything recently was not smooth for him. When he was about to focus on one matter, another would jump up, and he could not leave it to others, for example, this Abyssal Profound Beast Core. He was the only one who had the Eyes of Heaven.

Yun Qianxue grabbed Yun Lintian's arm and said. "Just leave it to us. You don't have to do everything by yourself."

Yun Lintian shook his head. "I'm not trying to do everything by myself, but I don't have a choice. First of all, we are too weak. It is too risky to bring all of you out. As for me, I can escape at any time. Secondly, I am the only one who can deal with Abyssal Energy at this moment. We have to wait until all of you are mastering the new profound art first. Lastly, all of you cannot come and go to this place as you wish. Hence, all of you have been forced to stay with me whenever we are going out."

Yun Qianxue and Yun Qingrou glanced at each other and saw the helplessness in each other's eyes. They felt distressed at being useless.

Yun Lintian organized his thoughts and said. "Qingrou, you go and list all the materials that help increase our soul power for me. Leave this Profound Beast Core's matter to me. Qianxue, wait for Ruanyu to choose the profound art and you go gather everyone afterward. I'll impart the profound art to them. Meilan, since we can't make a breakthrough, we can just practice other profound arts during this period. For example, let them practice music sorcery, painting, chess, and cooking. In the future, these skills will come in handy when we try to set up an intelligence network."

Yun Qingrou and Yun Meilan immediately left the living room after accepting the tasks, leaving Yun Qianxue and Yun Lintian behind.

"Are you hungry? Recently, I've studied new dishes. Do you want to try it?" Yun Qianxue said softly. Her eyes were full of tenderness. When Yun Lintian wasn't here, she would grow worried all the time. Seeing he was safe and sound, she could put her worry at ease.

Yun Lintian didn't reject her kindness and let her went to the kitchen. While waiting for the meal, he grabbed the Abyssal Profound Beast Core and activated his Eyes of Heaven to observe the inside.

Currently, the Abyssal Energy within the Profound Beast Core was swirling clockwise. Yun Lintian was staring at it for a while. When he was about to retract his gaze, the Abyssal Energy within it suddenly stopped moving and blended together into a small bead before exploding to all directions as though it was trying to break free.

"What the hell?" Yun Lintian furrowed his brows. This was the first time he saw Abyssal Energy moving as if it was alive. 

An idea flashed across his mind as he poured the Profound Spirit Liquid into the empty teacup before him and soaked the Profound Beast Core in it.

The result was as he expected, the Abyssal Energy within the Profound Beast Core was shrinking to the middle, did not dare to reach the side. 

"It can detect the threat… Maybe this is a high-level Abyssal Energy?" Yun Lintian muttered to himself. Similar to the Profound Spirit Liquid, Abyssal Energy seemed to have grades, too.

Yun Lintian picked the Profound Beast Core up again. This time, he poured his profound energy into it. Upon it detected profound energy, Abyssal Energy immediately swarmed toward the incoming profound energy like a hungry wolf. Instantaneously, Yun Lintian's profound energy was wholly devoured by the Abyssal Energy within the Profound Beast Core, and this Abyssal Energy seemed to expand a bit.

"I understand now. No wonder that black snake can improve very fast. It turns out this Profound Beast Core can absorb weak profound energy and turning it into its own power." Yun Lintian seemed to understand the secret behind the incredible improvement speed of the black snake.

"This is simply cheating!" Yun Lintian was exclaimed when he realized the truth. 

Usually, the practitioners could eat Profound Beast to improve their physiques and their profound strength. The Profound Beast was also the same. It could eat practitioner to nourish and improve its body. However, with this Abyssal Energy, not only the Profound Beast could absorb profound energy from the practitioner faster than before, but it also prevents the practitioner from eating it.

What does it mean? It meant sooner or later, human practitioners could not eat profound beast to nourish their bodies anymore. Unless they could get rid of the remaining Abyssal Energy within the Profound Beasts after killing them.

Of course, Yun Lintian had no problem as he had the best-grade Profound Spiritual Liquid with him. However, he wasn't sure if it could deal with the highest-grade Abyssal Energy. He could only hope it could still be effective against it.

After discovering this fact, Yun Lintian's expression turned heavy. Without a doubt, the Profound Beast would continue to rise while the human practitioner would constantly decline if the situation continued like this.

Yun Lintian wanted to give up and stayed in the Land of Beyond Heaven until reaching the peak Monarch Profound Realm, but he couldn't do it because he still needed to find resources.

He leaned his head on the sofa and closed his eyes, lamenting. "Life is so hard even with the plot armor."
