After feeling the terrifying power in this force, Qin Fang knew that if he didn't think of a way, he and the ruthless man would be doomed to fall today.

Thinking of this, Qin Fang directly opened the Difu Mall, and soon his eyes were fixed on the column of oversized items.

Immediately, his gaze fell on a transparent crystal called 'Rules of Destruction'.

'Rule of Destruction', the moment Qin Fang's gaze fell on the transparent crystal, all the introductions to this 'Rule of Destruction' appeared in his mind for the first time.

And when he understood the introduction of the 'Rules of Destruction', the whole person was excited.

Because the 'Destruction Rule' turned out to be the same as the previous spatial rules, and it also belonged to one of the original rules.

It's just that compared to the previous Netherworld mastered only one-ten-thousandth of the power of the space rules, the power contained in the destruction rules in the underworld mall is actually one-third of the power of the destruction rules.

Although it was only one-third, Qin Fang was sure that as long as he mastered it, he would definitely be able to deal with the immediate crisis, and it was not impossible to even make a counterattack!

Thinking of this, Qin Yi no longer hesitated, and directly used all the remaining Immortal Coins to purchase the Rules of Destruction.

And as Qin Fang confirmed the purchase, the prompt of the system also sounded in his mind at the same time.

"The items purchased by the host are non-repurchaseable items, do you want to continue to purchase?"

Hearing the system's prompt, Qin Fang was slightly stunned, and then looked at the introduction to the rules of destruction.

Then, as expected, he saw that behind the introduction to the Rules of Destruction, it was indeed written that it could only be purchased once.

Immediately after, Qin Fang's eyebrows furrowed slightly, and at the same time, his heart became more and more curious about this origin rule.

You know, the items in the Difu Mall, this is the first time he has seen an item that can only be purchased once.

From this point alone, it can be seen that the origin rule is not simple.

But now is clearly not the time to think about this, because the attack of retrograde rules is already in sight!

And now he knew that something like the "Rules of Destruction" was very valuable, and if he used it, he would be gone, but Qin Fang still decided to buy it.

Of course, there are not no more advanced items in the Underground Mall, which are only one-third of the power of the "Rules of Destruction".

But because of the previous purchase of the Silence Crystal, the amount of Immortal Coins he had left was no longer enough to support him in purchasing more advanced items.

Therefore, at the moment, it is the best choice to be able to resist the retrograde rule, which only has one-third of the power of the "Destruction Rule".

"Sure!"

Without hesitation, Qin Fang nodded directly in confirmation.

Although it can only be used once, Qin Fang doesn't care at all, because no matter how good the thing is, it has to be used with life.

Otherwise, it's no different from nothing!

As Qin Fanghua's words fell, Qin Fang felt that in his sea of consciousness, a crystal that exuded a strange power suddenly appeared.

The moment this crystal appeared, it suddenly turned into countless black points of light, then melted into his sea of consciousness, and finally disappeared.

And at the moment when these points of light merged into the sea of consciousness, Qin Fang's body couldn't help but be stunned.

After a brief blur of consciousness, he felt that he was already in a state of mystery.

The heavens and all the worlds seemed to be easily destroyed with just one thought from him.

The rule of destruction, what it stands for is destruction, destruction of everything!

"Whoosh!"

At this time, the attack of the retrograde rule is also instantaneous.

The target is exactly Qin Fang's eyebrows!

"Be careful!"

In the rear, the exclamation of a ruthless man sounded.

Hearing this, there was no trace of panic on Qin Fang's face!

After turning around and casting a smile to the ruthless man to signal her reassurance, Qin Fang looked at the black pillar of light that was already less than an inch away from the center of his eyebrows.

"Buzz!"

At this moment, a strange fluctuation suddenly came from the void.

Then he saw that in Qin Fang's eyes, two rays of destructive light suddenly erupted.

"Boom!"

"Bang!"

The moment the destructive light burst out of Qin Fang's eyes collided with the black pillar of light that was retrograde, he heard a loud "boom" sound come out, and the black pillar of light shattered!

"The Power of Destruction!"

At the moment when the black pillar of light shattered, the sound of retrograde regularity in the depths of the void also suddenly came out.

His voice was neither sad nor joyful, neither surprised nor alarmed, except for some confusion at first, which quickly calmed down, apparently he knew the destructive power of the "Rules of Destruction".

Ignoring the retrograde rules, Qin Fang's eyes flickered with cold light, looked into the depths of the void, and directly punched out!

"Whoosh!"

A punch was blasted out, and a black-purple divine light of destruction, like an arrow that had been off the string, headed towards the depths of the void.

"I didn't expect you to still retain one-third of the power of destruction, but I was careless!"

With that, the retrograde rule was silent, and the void fell into calm once again.

And after the Divine Light of Destruction entered the depths of the void, it was like a stone sinking into the sea, without splashing a single wave, and after a long time, there was a cold and ruthless voice from the void of retrograde rules.

And hearing the words of the retrograde rule, Qin Fang's brows couldn't help but furrow deeply.

He underestimated the vigilance of the retrograde rule!

"Click!"

"Boom!"

Immediately after that, the void finally couldn't withstand several battles and completely shattered.

One last glance at the void that was constantly beginning to crumble, Qin Fang turned around and stepped into the spatial passage with the ruthless man.

Qin Fang knew in his heart that the words of the retrograde rule just now seemed to be saying it to himself, but only he knew that it was not said to him.

Since it wasn't said to him, it could only be said to the system!

"System, what he means, can you understand?"

Qin Fang asked at the system in his heart.

"All the doubts in the host's heart, in the end, will eventually be solved, and the host only needs to know that the system and the host belong to a symbiotic relationship!"

After Qin Fang asked the doubts in his heart, the voice of the system sounded in his head.

After listening to the system's answer, Qin Fang just shook his head slightly, how could he not understand the meaning of the system, but it seemed that it was impossible to test the system.

However, he already had his own guesses about the system and the retrograde rules.

That is, the system has its own consciousness, and there must be some relationship between the system and the origin rule and the retrograde rule.

Because from the tone of the retrograde rule just now, he could infer that the retrograde rule is aware of the existence of the system, and the relationship seems to be unusual.

He didn't know what the relationship between the three was, but he had a hunch that he was getting closer and closer to the truth, and he could clearly feel this!

……

In the end, the battle against the retrograde rule ended in a hurry.

It is not so much that the retrograde rule is to kill himself, but it is a test of the system, but all this, Qin Fang has no heart to consider for the time being.

Because he has more important things to do now.
