"Gene potion, it turns out that you took the gene potion, no wonder there is a mutation!"

Tang Feng suddenly realized that long before this, he had already heard Mo Daocai say that not only Huaxia was researching gene potions in the world, but other major countries were also specializing in research.

It's just that for this kind of highly confidential matter, there is no information between countries, and they don't know the research progress of each country, but in general, the research progress of several powerful countries should be about the same.

"As far as I know, taking genetic potions, although you can gain strong strength in the short term, it usually doesn't live for more than three years at the cost of depleting the human body's potential. ”

When Tang Feng said this, he shook his head and said, "I didn't expect you to be so crazy. ”

Blood Thirteen waved the bat-like wings on his back, and sneered: "As long as I can kill you, even if I shorten my life, I can only live for three years, so what!"

Tang Feng stopped talking, and by now, the two sides had already been in an endless situation, and the other party had mutated, and his aura had skyrocketed again, as if he had reached the Nine Realms of Transformation Strength.

And Blood Thirteen was covered in an indescribable weirdness, and I don't know what kind of ability he had after taking the potion.

Thinking of this, Tang Feng's face was solemn, staring at the wings on the other party's back and said, "If my expectations are correct, your ability should be the wings behind you, it seems that your genetic potion should be a bat." ”

Blood Thirteen sneered: "I can't see it, you kid knows a lot!"

Speaking of this, he shook his head and said, "Force me to use my ability, at this time tonight, you kid will die without regrets!"

As he spoke, the wings on his back suddenly flicked slightly, and the whole person disappeared, this time it really disappeared out of thin air, even Tang Feng couldn't catch his trajectory.

"What a fast speed!" Tang Feng was taken aback.

At this moment, he only felt a piercing cold wind coming, and Blood Thirteen arrived in front of him and punched out.

Tang Feng subconsciously wanted to dodge, but at this time it was obviously too late, and with a bang, he only had time to avoid the vital parts, and his right shoulder was hit, and the whole person immediately staggered back.

There was another whoosh, and the Blood Thirteen wings continued to flap, and then broke through the air again, and the speed was incredibly fast.

"This level of speed has obviously surpassed the Grandmaster Realm and bought the Open Vein Venerable Realm!" Tang Feng gritted his teeth, undoubtedly feeling the pressure.

By this time, Tang Feng had already known that the other party's extraordinary abilities were all concentrated on the pair of black wings behind him, in other words, these black wings had brought him incomparable speed.

There was another swishing sound of breaking through the air, and the blood thirteen people actually swept to the side, poked out their claws out of thin air, and went straight to their throats.

Tang Feng was taken aback unexpectedly, fortunately, the other party's speed was fast, but it was far from being silent, every time he bullied in, the wind would blow around him in advance.

Because of this, even though Tang Feng couldn't accurately catch the opponent's figure, he was able to make a judgment a little in advance, but in this way, he fell into a passive situation.

He hurriedly dodged when he was in danger, but it was still too late, and although the other party did not crush his throat, he cut his chest at once.

A stream of blood spilled out, and Tang Feng was immediately injured.

"It's a pity!" Blood Thirteen didn't succeed, and couldn't help but look at his right claw and secretly shake his head.

"It's really difficult, it seems that you have to think about it, if you blindly fall into a passive situation, the consequences will be unimaginable!" Tang Feng's body swept sharply, and between the two sweeps, he withdrew seven or eight steps away.

Blood Thirteen didn't chase after him, just looked at him, and sneered confidently: "It's really a big joke to still want to fight now, as soon as my pair of black wings come out, under the Venerable of the Open Pulse Realm, I am already invincible!"

"That's not necessarily!" Tang Feng sneered.

Even though he is extremely fast against the counter, he has not improved much in terms of strength, in other words, he can only keep up with the opponent's reaction, and his strength is enough to crush the opponent.

However, it is not so easy to keep up with the speed of the other party!

"Stubborn!" Blood Thirteen sneered, swept his body again, and quickly killed.

With only a whooshing sound, his people swept closer and took Tang Feng's vital point.

In desperation, Tang Feng could only dodge, but when he retreated, Blood Thirteen was pressing step by step, using the peerless speed brought by the black wings to kill in and out.

For a while, Tang Feng fell into a disadvantage and fell into a passive situation, so he could only deal with it passively.

With a bang, he couldn't retreat, he was punched in the chest, and the whole person flew upside down.

It's just that his body hasn't yet steadied up, and the next moment Blood Thirteen is close, and his sharp claws poke into his neck.

Tang Feng was taken aback, and hurriedly jumped to the left to dodge, but he was still a little slower, his neck was cut open by the opponent's claws, and blood suddenly overflowed.

Fortunately, at the critical moment, he avoided his throat, but his neck was cut, but the blood vessels were not pinched.

"I'll see how long you can hide!" Blood Thirteen shouted angrily, flapping his black wings again and slaughtering.

"Damn!" Tang Feng gritted his teeth and scolded, as the so-called martial arts in the world are only fast and unbreakable, even if he has a full stomach of mastery, but under the suppression of the opponent's fast speed, all martial arts are useless.

Suddenly, there was another snort, Tang Feng's lower abdomen was injured, blood was spilled, and he stepped on his feet in a hurry, retreating like a monkey, only then did he avoid the other party's fatal blow.

Blood Thirteen continued to rush in, attacking like a raging storm, layer after layer, Tang Feng retreated again and again, and finally there was no way to retreat.

After several experiences, although he was not seriously injured all over his body, his whole body was covered with scaly wounds and blood, and the whole person looked quite embarrassed.

If it goes on like this, it will only be a matter of time before he loses, the speed of Blood Thirteen is too fast, the black wings are fanning, and his people can almost fly in the air.

And Blood Thirteen is very cunning, knowing his own shortcomings in strength, and does not contend with Tang Feng head-on, but just uses his peerless speed to constantly swim and launch attacks again and again.

Although each attack is not enough to severely damage the opponent, but he has enough patience, as the so-called thousand-mile embankment is destroyed in the anthill, as long as he keeps fighting, he will consume the opponent to death even if he consumes it again and again.

Of course, Tang Feng could see the other party's thoughts, but even if he understood, there was nothing he could do at the moment.

"Boy, don't resist stubbornly, I know that your martial arts are powerful, and your dragon fist is powerful, but I won't give you a chance to show it, under the absolute speed suppression of Lord Ben, any of your peerless martial arts skills are in vain!"

Blood Thirteen laughed wildly, looking at Tang Feng, who was embarrassed in front of him, a smile of victory had appeared on his face.
