Seeing the hidden hint, I dug out the masonry treasure chest at the beginning!

Underworld, Polar Night Canyon.

Su Ming stood on the city wall, looking at the base gradually covered by white halo, a smile could not help but appear on the corner of his mouth.

Immediately, he sat down cross-legged, and took out a palm-sized round stone from his arms, with a small sword carved on it, which looked simple and unpretentious.

This simple and unsophisticated stone is exactly the mysterious sword stone whose quality has reached the Dao level.

As for the level of 'Tao Pin', Su Ming didn't know.

However, what he can be sure of is that this stone is definitely not ordinary!
Since he got this sword stone, he hasn't had time to study it carefully. Now, taking advantage of the base upgrade, he has time to study it.

Dao grade, this is a grade that has never been seen before.

Su Ming was naturally impatient.

Coming to this treacherous world full of unknowns and dangers, he has experienced a lot and naturally learned a lot.

He is very clear that in this world, only strength is everything.

Everything else is false!

Moreover, one must be strong enough to be able to have more sense of security.

It's just that this treacherous world is too dangerous, even if Su Ming's strength is getting stronger and stronger now, he still doesn't have much sense of security.

Perhaps, only in this base city can one relax a little bit.

The more powerful you are, the more you know.

The doubts and shock in Su Ming's heart deepened. What is the truth of this world?
What are Abyss and Xuanzhu?
What is the relationship between them?
The sword stone, the chain of arresting souls, the map of the abyss... no matter which one it is, it is deeply engraved in his heart, and there is no mystery in it.

"Hey~ It's useless to think so much, let's take a look at the function of this sword stone first!"

Pictures and nouns flashed through his mind, almost disturbing his Dao Heart.

Fortunately, Su Ming was determined, so he quickly reacted and waved all of them away, focusing all his attention on the sword stone in his hand.

The sword stone is so unremarkable, except for the sharp sword seal engraved on it, it is just an ordinary mountain rock no matter how you look at it.

But Su Ming knew that it would never be as ordinary as it appeared on the surface.

After all, the hidden hint means that you can comprehend the way of the sword through it!

By the way, mental attack!

The hidden hint shows that as long as you use your mental power to continuously attack the sword stone, you can quickly comprehend the way of the sword.

Thinking of this, Su Ming directly mobilized his mental power and swept towards the sword stone.

hum~
When the transparent spiritual force just touched the sword stone, Su Ming only felt his eyes go dark.

In the next second, it appeared in a space.

"Huh? That is?"

Su Ming opened his eyes and looked ahead, his heart was full of shock.

I saw a man in black robe standing on a high mountain in front of him holding a long sword behind his back.

He stood there, the black robe on his body fluttering, although there was no unnecessary movement, it gave off an extremely powerful sense of oppression.

Immediately, he raised his hand slightly, and the sword in his hand was powerful, stirring up the situation.

In the sky, the white clouds continuously condensed as he swung his sword, turning into black in an instant.

Click!

The man swung the long sword in his hand, and it turned into a beam of sword energy that roared towards Su Ming, and thunder fell from the sky on top of it, like a demon god!
Jianguang came with thunder and lightning in an instant.

Su Ming's pupils continued to dilate, and he had no time to dodge, and was directly split in half by him.

"Hmm~"

In the next second, Su Ming's eyes on the city wall opened suddenly, traces of blood involuntarily overflowed from his ears.

"Head hurts"

He covered his head, feeling a splitting headache, as if the melon seeds in his head were being torn apart, looking around, advanced psychedelic, layer upon layer.

With the sound of 'plop', Su Ming fell directly from the city wall and passed out completely.

hum~
Just at this moment, the sword stone suddenly emitted a gleaming white light, and the white light continued to condense and finally turned into a white sword seed the size of a grain of rice and sank into Su Ming's forehead.

At this moment, Su Ming's body who was lying on the ground couldn't help shaking, and the pained expression on his face also improved a bit.

Half a day later, Su Ming woke up leisurely.

"This is? Sword species!"

"Fuck, it's worthy of being a Dao grade sword stone. The first time I practiced, it actually made me condense the sword species!"

"By the way, I also have a dark sword light fish egg. Eating it can speed up the comprehension of the sword power. Only after comprehending the sword power can the initial power of the sword be exerted!"

Su Ming sat up and immediately understood what was going on.

Immediately, he couldn't wait to take out the fish egg, and directly swallowed it with his head up. Suddenly, a mysterious force rushed straight to the sky, and his spiritual power became more and more active.

At this moment, the sword that he saw from the sword stone space before kept reappearing and rehearsing in his mind.

Boom!Click!
In his mind, the sword light, which he couldn't see clearly at first, actually slowed down, and the movement of the man in black robe raising his hand and swinging his sword was constantly broken down by Su Ming.

Every move, every style cannot escape.

Undoubtedly, this is precisely the function of the fish egg, which allows Su Ming to see the trajectory and application of this move so clearly.

Su Ming continued to sit cross-legged, taking advantage of the effect of the fish eggs to greedily comprehend that heaven-defying sword.
