The first ability Zachary confirmed was his penetrative vision. This ability allowed him to see through not just inanimate objects but also living beings, with nothing able to block the sight of the Stone Eye. Furthermore, the Stone Eye could actively adjust the degree of penetration.

Beyond that, the Stone Eye also possessed the ability to observe energy flows. With this ability, Liu Zi could deduce the cultivation level of others by watching these flows.

But that was not all. After obtaining the Stone Eye, the most important thing Liu Zi did was to develop a cultivation method by observing the patterns of Inner Breath flow within the bodies of martial artists.

Even though China had made the Body Tempering Realm cultivation techniques available to the entire country, the common survivors in this small encampment were unaware of them.

Liu Zi himself was also ignorant of them, but after he reached the Body Tempering Realm using the cultivation method he had imitated, the camp then told him about the cultivation techniques that the Imperial Court had announced, which should have been unconditionally taught to all.

It was from then on that Liu Zi, who should have led an inconspicuous life lost among the masses, embarked on a different path.

Even though Liu Zi had only discovered these two functions of the Stone Eye so far, they were enough to change his destiny.

However, Liu Zi was not content. Whether it was because of his age or simply because he had poor aptitude for cultivation, his progress was very slow.

Nonetheless, Liu Zi didn’t become too heartbroken. Having had the chance to change his fate, he was not satisfied with just that, so whenever he had spare time, he would take out the Stone Eye for research, hoping to discover other functions that might further his progress.

The day he saw Dong Tianyu flying happened to be a coincidence; at that time, he was testing the Stone Eye, attempting to uncover its other functions.

When Dong Tianyu heard this, he looked at Liu Zi, who was not showing signs of excruciating pain, and immediately sensed something was amiss.

That day, after he felt Liu Zi’s gaze, Dong Tianyu had used his Divine Sense to observe Liu Zi in return and found no trace of the Stone Eye that Liu Zi mentioned.

Dong Tianyu remembered clearly that he had scrutinized not only Liu Zi himself with his Divine Sense but also the inside of his room, and he had not spotted the Stone Eye that Liu Zi spoke of.

Yet now, Liu Zi was saying that he had been holding the Stone Eye for testing all along, which was different from what Dong Tianyu had observed with his Divine Sense.

But Dong Tianyu didn’t doubt Liu Zi’s earlier description, as it had already been proven that Liu Zi had no power to resist enchantments.

When Liu Zi had left the encampment with Dong Tianyu, Dong Tianyu had already scanned his body with Divine Sense, confirming that Liu Zi was not carrying any suspicious items.

But if Liu Zi wasn’t lying just now, then the Stone Eye he spoke of was something undetectable by Divine Sense.

Such an important item; if it were Dong Tianyu, he would definitely carry it on his person, even knowing he might face danger. According to most people’s character, they would rather be the ’treasure delivering child’ and keep it with them.

Because if they didn’t and managed to return safely only to find it stolen by others, that would be a lifelong regret.

It’s like that saying in the comedy sketch: nothing is more distressing in life than being alive with no money left and dying with money unspent.

Honestly, if it were Dong Tianyu, he would rather be someone who dies with money unspent than experience being alive with no money left.

Between being the ’treasure delivering child’ and being penniless, Dong Tianyu would prefer the former, much like that classic saying: "After I die, let the floodwaters rage. As long as I have enjoyed my life while I lived."

When it came to Liu Zi, Dong Tianyu believed he was that kind of person too. Moreover, through his self-introduction, Dong Tianyu knew that Liu Zi did not have any relatives in the encampment, thus it was unlikely he would transfer the item to someone else. The object should currently be on his person.

With this in mind, Dong Tianyu subconsciously scanned him with Divine Sense once more, but the result was exactly the same as before, revealing no special items on his person during the scan with Divine Sense.

Liu Zi, observing Dong Tianyu staring at him in silence, guessed that Dong Tianyu might have some detection technique at work on him, and subconsciously stepped back a few paces.

And it was precisely this subconscious action of Liu Zi that made Dong Tianyu even more certain of his own conjecture: the Stone Eye was carried by Liu Zi, and the item was indeed on his person now.

At this moment, Dong Tianyu wasn’t planning to continue questioning Liu Zi but instead used a physical approach to knock him out directly.

After confirming that Liu Zi had fallen unconscious, Dong Tianyu used the Art of Controlling Objects to strip him clean.

Dong Tianyu left the completely nude Liu Zi to the side, then neatly laid out all the items taken off Liu Zi on the ground.

Even though Liu Zi said he had found an eye of a stone statue, because of his earlier attempt to bypass the enchantment, Dong Tianyu judged that the other party hadn’t told the complete truth.

Hence, Dong Tianyu made such a decisive move to knock him out, preparing to find the item himself from Liu Zi’s person.

Looking at Liu Zi lying not far away and then at the items on the ground, Dong Tianyu ultimately decided to perform a check on Liu Zi first.

Although Liu Zi was now bare thanks to Dong Tianyu, he still had places on his body where he could hide something.
