The night was deep, and even in the "City That Never Sleeps", most of the people were asleep, but there was a tense atmosphere in the liaison station.

After hearing that Xiao Diamond was about to be promoted, Ye Hui specially led the personal guards to guard the liaison station and surrounded it, and Ye Yu himself was completely prepared to ensure that no one would disturb Xiao Diamond's promotion.

"Are you alright, are you a little sure?" Ye Hao held the hand of the little diamond, and the latter's face was firm, "Don't worry, no problem, with my ability, isn't it easy to be promoted to a brain domain evolutionary?" ”

"Yes, it is necessary to have this optimistic spirit, and the optimistic family will never back down!" Ye Yu laughed and patted him on the shoulder, and the little drill grinned in pain, "Okay, I'm going to start the promotion, according to the experience of the controller of the Benlong City Liaison Station, as long as you ensure quiet when you are promoted." ”

"Don't worry, whoever bothers you, I'll sew his mouth shut!" Ye Yu patted his chest. The little diamond glanced at everyone, nodded, and turned to close the door.

Ye Yu and Ah Fei immediately stood at the door, and the other guards scattered.

A figure hurriedly ran over, and the guards were about to hold it, but Ye Yu stepped forward to meet the comer.

He ...... He went in? Xiao Xin asked in a low voice, Ye Yu nodded, the latter pursed his lips in anger, tears rolling in his eyes, "He didn't say a word to me, he ......"

"Well...... Ye Yu was a little embarrassed, "I think, he's probably worried about you, and he doesn't want you to be too nervous, don't worry, it's absolutely fine." ”

Xiao Xin hummed and stood outside the door with Ye Yu and the others.

Inside the ashram, the little drill sat cross-legged, he took a few long breaths, adjusted his state, and pressed his right hand firmly on the container.

"Verified, Horcrux open." With the sound of cold machinery, the container slowly opened, and the liquid soul energy inside lost its restraint and immediately began to turn into a thick gray air current.

The little drill took a deep breath, only to see that the gray soul energy seemed to be attracted by something, and drilled into his mouth and nose, he was like a long whale sucking water, swallowing the soul energy airflow, as a large amount of soul energy airflow poured into his brain, the little diamond felt that his brain was changing rapidly.

Brain domain evolutionaries can't strengthen their bodies through soul energy, but they can use soul energy to strengthen their brains, and the little drill feels that every part of their brain tissue, brain marrow, and cells are rapidly evolving under the action of soul energy.

This kind of evolution gave him a sense of fluttering, the brain is like a baby waiting to be fed, constantly absorbing nutrients, the little diamond feels as if a cloud shrouded in his brain is suddenly removed, and the bright sunlight shines in, making everything seem so transparent and clear. Suddenly, a lot of unsolved doubts in the past, a lot of incomprehensible knowledge in research, instantly became organized, and ideas continued to flow and weave in the brain.

It's such a cool feeling! When Ye Yu was promoted, he also experienced this feeling, but Ye Yu was a pleasure in physical functions, and the little drill was a smooth thinking, as if a person was struggling with a problem for a long time, and suddenly his inspiration exploded overnight, and he couldn't help but get up and laugh out loud.

A smile slowly appeared on the face of the little diamond, as the soul energy continued to inhale, his thinking expanded rapidly, in a trance, he felt that he was rising, his body was out of the ground, flying upward, his eyes swept across the vast earth, swept through the mountains, valleys and dense forests, he saw the life and decline of plants and trees, saw the abundance and exhaustion of rivers, saw the fighting and evolution of soul beasts, and saw the survival and death of human beings. All things, all living beings and all souls are included in the eyes. Then he looked up at the vastness of the sky, the mysterious world hidden behind the gray sky. An inexplicable intuition told him that the gray canopy was no longer the sky in reality, it was the "veil" of this world, and behind that veil, the truth of the world was hidden. As long as you break through the gray canopy, you can see the truth of this world!

This stage is the most important stage of "Heavenly Knowledge" in promotion, and Xiao Yunfei and the controller of the Benlong City Liaison Station have all experienced this stage. And they told the little diamond that according to the rumors, the deeper you go into the mysterious world, the longer you support it, the more "truth" you can see in this world, and the higher the achievements you will get after promotion.

The little diamond's "thoughts" slowly melted into the canopy, and in an instant, countless fragments flickered into his mind like a montage of movies, and the picture of the whole world spread out in front of him, so much knowledge he knew and didn't know poured into his brain like a tide.

However, in the experience of the impact of knowledge, the little diamond not only did not feel pain, but felt a great happiness, in this moment, he was like a god who controlled the world, his every action, all contained the truth of heaven and earth, every fragment of knowledge, made him feel full of soul.

In fact, these fragments of knowledge will not directly become the property of the little diamond, otherwise he will directly have the same power as the creator, but the longer he absorbs it, the more comfortable he will be when he learns and studies this knowledge in the future, and the more often his inspiration will explode. In fact, many brain domain evolutionaries will selectively focus on absorbing certain types of knowledge fragments at this step, which also leads to different research directions of brain domain evolutionists, such as Xiao Yunfei, his ability in artificial intelligence is far stronger than other brain domain evolutionaries, the master of Benlong City Liaison Station loves demon refining, that is, the direction of biochemistry, Xiao Yunfei's master, the former master of Tianfeng City Liaison Station, likes to study human weapons and genetic modification, while Mr. Swallow's research direction is more inclined to soul beasts.

So, which direction do you want to choose? With questions, the little diamond's mind went deep into the gray sky, feeling the pleasure of being surrounded and washed by the sea of knowledge, and he felt that he was almost about to leap up, out of the low-level thinking of human beings, out of the comfort of meaningless emotions, and into the endless and infinite ocean of knowledge.

A happy smile appeared on his face, as if he had entered the realm of "great bliss" in Buddhism, and at this moment, if he had not sat still, he would almost dance and cheer with joy.
