How to prove it? Su Mu actually couldn't prove it at all.

Not to mention that before Su Mu came to this world, he was only a sophomore in high school, and he had never even been exposed to university textbooks, let alone the so-called cutting-edge knowledge beyond textbooks.

And even in terms of this world, in the long history of the continent, the powerhouses who have really broken through the limit of the big character level are almost all stories that only exist in legends.

Su Mu didn't even have a way to guarantee the authenticity of these stories.

Not to mention that I have to point out to others the so-called advanced method of word study.

In the final analysis, Su Mu was still just taking advantage of the other party's ambitions at the moment, bringing the other party into his trap little by little. It's just that whether the other party will jump into the trap or not, there is no doubt that even Su Mu himself is not sure.

"I can't prove it either. ”

Su Mu was still staring at the huge pale golden pupils, but his mouth faintly expressed a nonchalant denial.

"As you yourself said, I will not believe that you will not be slaughtered thousands of miles after getting out of trouble because of your assurances. But on the other hand, as long as I can't point you in the right direction, you'll never be sure I've found a way. ”

As Su Mu spoke, he also struggled to draw a trace of mockery at the corner of his mouth.

Then he threw the paradox thrown by the old man of the dragon directly back to the old man himself:

"But in fact, I can't give you a final answer in advance. After all, if I really gave the answer to you, then with the realm and strength of my current rebirth, I wouldn't believe that you didn't kill me immediately. ”

"So the only thing you can do is force yourself to believe me. If you still try to get an answer from me, then you can only believe what I say, and do what I want and never kill indiscriminately. ”

"If you agree to my request, then we will leave this dark underworld together. And I will faithfully show you the path you need after regaining the realm of the past. ”

"Now it's just a matter of ...... Will you believe me again?"

......

"I won't believe you. ”

The old man of the dragon was not easily disturbed by his thoughts because of Su Mu's step-by-step approach.

Even at this moment, Su Mu has already constructed a lie that is difficult to debunk. But as long as this lie cannot be believed by the dragon elder, then it will naturally remain worthless.

"I need evidence, and if you can't produce any evidence...... Apparently I will not trust you as a despicable liar again after tens of thousands of years of trapping!"

Tens of thousands of years of loneliness have undoubtedly planted absolute suspicion of Su Mu in the heart of the old man of the dragon.

As long as Su Mu in front of him still can't come up with more convincing evidence, the old man of the dragon will not agree to his request at all, and the so-called deal is still just a bubble.

However, what even the old man of the dragon didn't expect was that in the face of its suspicious gaze without hesitation, Su Mu didn't care in the slightest.

On the contrary, it was as if he had already guessed this distrust, and the corners of his mouth once again outlined a trace of mockery.

Even Su Mu's next sentence immediately filled the extremely cold-minded old man of the dragon with a lot of surprise and surprise again:

"I can prove the key, but I won't show you everything. After all, in your realm, if I really present everything, you will naturally be able to see through the key points. ”

"But if you still can't believe what I say after I've proven some of it, then you deserve to be at your current level forever, and you deserve to be deceived by me for 10,000 years. ”

Su Mu's words were undoubtedly strongly aggressive.

Since the old man of the dragon was so resolute, Su Mu could only use more brutal means to try to directly blast through the opponent's psychological defense.

And Su Mu's consideration of the psychology of the strong man really found the only weak point in the old man's mental defense.

In the face of Su Mu's aggressiveness, the old man of the dragon said in a deep voice with a calm face:

"You prove it to me first!"

......

Since the old man of the giant dragon gave Su Mu a chance to prove it, it naturally means that Ming Su Mu's threat is in the other party's heart, and there is a little more place to hesitate.

Where there is hesitation, there is naturally a way to break through.

At this moment, the only thing Su Mu has to do is ...... Immediately show something beyond the ordinary, and use it to convince the other person of what you say.

The execution rack made of cold ice slowly shattered and melted behind Su Mu.

And on the ice shelf, Su Mu finally returned to the solid ground after a long absence, and stood firmly in front of the old man of the dragon with his somewhat stinging feet.

"What you're trying to present, it's better not for me to find out that it's still a lie. Otherwise, even if you are willing to let me go, I will still torture you for decades before making a decision. ”

In addition to the strong threat, the words of the dragon old man were naturally mixed with tens of thousands of years of resentment.

But when Su Mu heard this, his expression did not change at all.

Still calm, feeling the Qi energy slowly awakening in his body, and letting these Qi energy be injected into his body first, bringing the long-lost warmth.

It wasn't until a long time later, when the warm Qi flow completely rewrapped Su Mu, so that every joint around Su Mu's body was restored to a state that could be used.

At this time, Su Mu finally spoke:

"In fact, the so-called research level is not a certain state higher than the big character level, but a kind of ability based on the realm of the big character level and able to change the rules of the world. ”

According to Su Mu's assumption, the four levels of elementary, medium, high, and large are actually passively accepting textbook knowledge, and the essence is still learning the application of the laws of this world.

But beyond this limitation, the level of research is to discover new theories and knowledge on your own.

From the perspective of the brain world, it is natural to create new world rules, so there is the so-called "ability to change the rules of the world".

Su Mu's deduction from his own memory obviously immediately struck the heart of the old man of the dragon.

Regarding the mysterious and ethereal research level, the old man of the dragon undoubtedly already had a certain degree of his own understanding. And seeing that Su Mu only used the rank of the seventh order of Chinese characters to say such an advanced opinion, the old man of the dragon was convinced of what Su Mu said, and after all, it still increased slightly by a few points.

Seeing this, Su Mu did not show joy, but continued with this statement:

"Since the core thing of the research level is how to change the existing rules of the world, so as to create something that this world does not have. So the best way to prove that path is actually some kind of rule that does not exist in this world...... Give me a little bit of it in front of you!"

......

I don't know when it began, Su Mu's address to the old man of the dragon has changed from a very respectful "you" to an extremely ordinary "you".

But this small change was not even noticed by the old man of the dragon himself.

Because with Su Mu's every move, even the old man of the dragon himself now recognizes that Su Mu does have the right to talk to him on an equal footing.

Therefore, at this moment, when Su Mu gently contained Qi energy with a determined face.

Even the terrifying dragon old man finally subconsciously narrowed his eyes, looked at Su Mu with a look full of expectation, and waited for Su Mu's next appearance.

Tiny Qi energy gently flowed out of Su Mu's fingertips and swirled in the air.

And in the swirling of this Qi energy, it also slowly transformed into a different appearance.

With such a faint amount of Qi energy, it is naturally impossible to contain any profound magic or fighting skills. But with the slow transformation of Qi Neng, the eyes of the giant dragon old man at this time suddenly burst out with a few essences.

I saw that the faint Qi energy was actually solidified into a small piece of hard solid in the circulation.

And this solid itself...... But it's the metal substance that is used to make weapons!

On the premise that Su Mu had not summoned a concrete image at all, he successfully condensed a solid substance called "metal" out of thin air in his own Qi energy.

You know, even the earth fissure magic, which is known for its ability to condense, can only create certain stones that contain metal components.

Metals that must be artificially smelted to extract cannot be made even by earth rift mages.

After all, the essence of magic has always been the application of the rules of the world, and it is impossible to directly create those substances that exist in an unnatural state.

However, today's Su Mu is so understated and directly created metal.

No matter how rough this piece of metal is...... But this ability to directly scan metals is still the most amazing discovery in the world!
