Xin Yuan ran wantonly in the dark, the ground, ceiling, wall or all kinds of debris piles were his runway, which would not affect his speed at all, but allowed him to complete many actions that ordinary people could not imagine, as if gravity had lost its effect on him.

Doing this largely relied on the full-scale Crimson Vision, which allowed him to observe the surrounding terrain and the enemy's location in great detail, and control all information from the most basic energy level, and more importantly, his new eight arthropods.

After entering the D rank, the Scarlet Hunter's source fire structure was combined with his own rune stone core altar structure, and after the completion of the Scarlet Hunter's core altar structure, the Crimson Hunter had reached a theoretical state of completeness and obtained the further refinement of the rune structure, thus activating the advanced ability of the Crimson Hunter that belonged to him, the Void Hunting Spike, which could form arthropods of any size that could appear from any angle within a certain range around himself - of course, this is not a real physical existence, Rather, it is a short-lived structure formed after the spiritual level interferes with the material level, and the existence time, piercing speed, sharpness and hardness and other indicators are completely determined by the amount of source fire he outputs.

With this new ability, it not only means that he has eight extremely sharp blades that can attack from all kinds of unimaginable angles, but also gives him a lot of auxiliary abilities that can be used in many places. For example, when he jumps in the air, he forms arthropods to borrow force or fix on the wall on the side, which can form his original physical movement state, form his multi-terrain travel ability, and misjudge his trajectory in battle.

He had previously learned about the D-Class by reading the Faceling's internal profiles.

The D-class is also hierarchical, and the first entry into the D-class and the completion of the control of the structural source and fire conversion control are two completely different concepts.

In the E rank, although the source fire of each person of this level has its own special properties, due to the imperfection of the ontology structure, it can only use the crude and simple way of energy release and explosion to fight, at most the difference in energy nature, but in fact, there is not much difference in nature.

And after reaching the D-level, because the individual structure has been basically established, the source fire has formed a variety of rich and changeable branch abilities under the effect of complete modularity, and then the difference between each ability is truly reflected.

It is precisely because of the different branch abilities of the D-rank post-abilities that the fighting styles of each D-rank ability are also very different. At the beginning of the D-level, he is still adapting to this transformation and looking for a suitable way to fight, and at the intermediate level, his own ability can already assist his own combat well, and after reaching the advanced level, the ability and self have formed a very tacit whole.

F-class is a Rambo-style superman in front of ordinary people, and outright weak in front of E-class, but E-class is vulnerable in front of D-class, which is not only the gap between absolute energy levels, but also the destructive power that the same power can exert in the hands of people of different levels is also very different. For example, the strength of 1 unit can be increased to 5 units in the F-rank hand, then it can be increased to 20 units in the E-rank hand, and it can even be expanded to more than 100 units in the D-rank, which is the difference in strength.

Not only that, after entering the D-class, the transformation of its own structure will be completed, and it will continue to generate the source fire and circulate in the body, strengthening the physical fitness all the time, the efficiency is much higher than that of the E-level, and the growth rate is completely up a notch.

Originally, Xin Yuan still needed a certain amount of time to find a suitable combat method after entering the D rank, but under the catalyst of this sudden and just right intensity battle, this time was greatly shortened, and the prototype of his new combat method had been formed.

And Xu Lao, they don't understand, they are just a whetstone sent to the door in Xin Yuan's eyes.

……

Hu Zhen clearly felt that his forehead and back were already soaked.

In the ever-widening passage, only one subordinate was left between Xin Yuan and him who was about to collapse mentally, and the other combatants had been lost, and their lifeless bodies were drawn into deeper black shadows in the shadows of the corridor.

In those shadows, Hu Zhen could clearly feel that Xin Yuan was there, but he couldn't see or hear, there was no trace, and he was silent, as if he was naturally part of the shadows, not opening his mouth or making a sound, just staring coldly, like a predator about to attack.

That staring gaze fell on Hu Zhen like substance, and he even felt a faint tingling sensation, which was purely the feeling of being locked by a qi that was stronger than himself, which made him dare not move casually, for fear of revealing the slightest flaw.

But it's not a thing to be stalemate like this, the pressure brought by the qi machine is not a one-time thing, but constantly superimposed, once he can't hold it anymore, that's when Xin Yuan launches a thunderous blow, and at that time he doesn't even have the strength to resist.

Hu Zhen knew that he couldn't continue like this, so he gritted his teeth, pulled the subordinates in front of him behind him, and shouted: "Take Xu Lao away!" I'll ......."

Before the words fell, the shadows suddenly twisted, Xin Yuan had already rushed out, and launched a charge towards Hu Zhen at an extremely high speed, and faster than him was the cold edge that suddenly stood out in the void.

Hu Zhen shouted, the black fire ball in his hand suddenly expanded, and the invisible air flow was instantly pulled wildly, and the surrounding furniture, lamps and even the tiles on the wall were pulled in front of him, turning into an invisible torrent and rushing forward.

In the next moment, the torrent completely submerged Xin Yuan's figure.

But just a moment later, Xin Yuan appeared behind the torrent, and in front of him was Hu Zhen.

Tear and pull!

As if the blade was tearing through the cloth, the black flames suddenly exploded, completely filling the entire corridor, but in an instant, it split into countless petals in a few vague and writhing cold lights, scattering in all directions.

Hu Zhen snorted, his body bounced on the wall on the side, and he smashed through the wall in one fell swoop, crashing into the room inside, dozens of wounds on his body sprayed blood at the same time, the most serious thing was that his right hand was directly cut between the middle finger and ring finger, all the way to the elbow, tearing the hand in half.

Xin Yuan didn't stop, chasing after Xu Lao, who had not yet run a few steps away, and the last member of the battle team.

Seeing that Hu Zhen couldn't stop Xin Yuan for a moment, the nerves of the only remaining member of the combat team, which was already on the verge of collapse, were completely broken, he screamed wildly, threw all the grenades on his body forward in an instant, and then turned his head and ran, not caring about Xu Lao, who was originally escorted by him on the side.

Polymerize, form, explode, disappear.

The edge of the dead silence flashed, and the grenade rolling in the air was suddenly cut into several sections, and the detonating device in it was completely destroyed, and the remaining edge did not stop at all, pointing directly at Xu Lao, who was standing in front of him.

"That's it."

A voice rang out.

The pupils on Old Xu's expressionless face suddenly dilated to the extreme. Less than ten centimeters in front of his eyebrows, a sharp blade emerged from the void, crystallized, and then shattered, turning into countless crystalline dust sprinkled with dust, and with it, the members of the combat team who fled behind.

Han Lei walked out of the shadows on the side and faced Xin Yuan.

"If you're out of breath, go get some sleep."

Xin Yuan stood still and looked at the tall and thin young man in front of him, the scarlet luster in his eyes wandering.

After a few breaths, he suddenly turned and stepped into the shadows.
