Ace suddenly felt a foreign Qi enter his brain, and he felt his head split as a huge pain attack him. He felt this Qi was drilling inside his knowledge sea forcefully was Gordon's martial sense!

He never thought this soul search would be such a vicious method, it wasn't like his gentle soul probing at all.

Gordon wanted to use only superficial soul search on Ace since the full prowess of it will turn him into a 'vegetable'. Furthermore, this technique was for a soul realm cultivator, but he was using it on the river core realm, only he can do this since his real cultivation was much higher than his clone, but this action has its consequences. Like it would take a huge toll on Gordon's body and mind, or even cause a back backlash if he used it for an excessive amount of time.

However, Gordon was confident to finish it in a few moments since Ace was only Qi 'river' cultivator. Although he can't sense Ace's cultivation. But after his exchange with him, he was completely sure that Ace was only at Qi 'river'. He only thought of this as a Concealment Skill left behind by his parents as well.

But the moment Gordon used the soul search on Ace, his calm expression changed ever so slightly, first because he can't go past his mental defensive with the power he was using right now.

'Hmm? Why is this brat's mental defense so high? Is it because of the slate?' Gordon instantly reached this own conclusion, since it was the only possible explanation he could think of.

The very next moment, Gordon increased the output of his power and finally managed to breakthrough Ace's mental defense.

However, what he didn't know was Ace was the one who lowered his mental defense or Gordon wouldn't find out about his soul cultivation and also spare himself from the excruciating pain.

But Ace never thought the soul search would become even more dominant and menacing after breaking past his mental defense! He suddenly felt the pain he once experienced when the system first time enter his head!

But he gritted his teeth and endure since he knew the time of regret was way past now, and he was hoping for the system to act, or he'll die right now!

'What a strong will!' Gordon silently admired Ace's endurance because if it was someone else they would've screaming right now and begging for mercy even though he was using only thirty percent prowess of soul search!

'Since you can endure this much, I won't have to worry about you turning into a vegetable anymore. Let's see if you hide anything from me about the technique or not!'

Gordon's martial sense instantly goes toward Ace's knowledge sea however, Gordon was instantly gobsmacked the moment he saw Ace's knowledge sea.

'H-how is this possible?!' He was completely flabbergasted this time.

Typically, a normal person's knowledge sea looked like a large lake with shimmering stars inside, those stars represent a person's memory fragments. The brighter the star, the deeper the memory fragments.

However, if a person was a one in a million genius, then his knowledge sea would be like a large river, and it would be covered by a defensive mist, so it would be hard to search it.

Nevertheless, if a person was a one in a billion genius, then his knowledge would truly be like a sea with thick mist protecting it, and it was quite troublesome to soul search this kind of person and if the person using soul search was not careful enough, he can even suffer a backlash and table can turn on him in an instant!

However, this type of genius was extremely rare in Golden Sky World and if this kind of genius appeared in any race, they would do anything to protect it, even if this mean the war with other races.

This type of genius has extremely fast cultivation speed and comprehending abilities, they can understand a technique, art, or skill within days that will take a normal person almost a year!

These geniuses were the hope of their races and always protected by powerful protectors wherever they go, and killing them was extremely cumbersome.

However, Gordon was shocked silly by Ace knowledge sea because it was almost like an endless inky ocean and there weren't any mist or memory stars in it because it was pitch black, there was nothing but darkness!

Furthermore, the more Gordon saw, the more he felt this was more of an endless abyss than a knowledge sea and if he dared to try searching it, he'll forever be lost in it!

Suddenly, Gordon felt a chill run down his spine and he felt he was thrown into an icy lake abruptly, he just felt someone terrifying just gaze at him from that inky sea!

'If you gaze into the abyss, the abyss gazes also into you!'

This phase suddenly came into Gordon's mind for some reason, he wanted to quickly retract his martial sense he had a feeling someone was very wrong with Ace's dark knowledge sea, and he had a feeling something was terrifying residing here.

However, when he tried to retract his martial sense from Ace's dark knowledge sea he found out he can't, furthermore, he was glued to his place like a state!

Suddenly, he felt a sliver of wind, but Gordon knew wind couldn't exist in a knowledge sea, and how could he have felt a sliver of wind?

The moment he felt this sliver of wind, his martial sense turned into nothingness!

Ace knowledge sea returned to its tranquil state after Gordon's martial sense was turned into smithereens by an unknown sliver of wind.

Ace did not know what had happened inside his knowledge sea, nor he could gaze at it until he reached an extremely high realm.

However, for some reason, Gordon's calm rosy face has turned deserted and ashen as his soul suddenly trembled.

The pain from soul search instantly vanished as well, and Ace's eyes lit like torches in elation, and he knew his plan was succeeded!
