For five days in a row, Li Feng almost gathered elite scholars, but in the end, he was still helpless against this unknown metal celestial circle.

On this day, he still didn't give up trying some methods of sword deviance, since normal chemical reactions and brute force can't crack it, then another seemingly unreliable, even very chaotic means of mystery.

As a result, Li Feng made some other attempts to use this celestial circle.

For example, dripping blood.

No way.

For example, using the power of the mind to infuse.

Still no.

In the end, he tried to keep asking the blood crystal space to raise blood essence, but it still didn't work.

Crazy, try your best, there is no way to crack this celestial circle.

What the hell is it?

Could it be that more than 3,000 years ago, the products of aliens were so intolerable?

Oh my God, after many experts speculated, this is a metal ball that even nuclear forces cannot explode.

This is definitely a supreme treasure, even if you don't know what it is, even if you don't know what its specific role and ability is.

But the unknown and powerful metal on its body surface alone was enough to make Li Feng look crazy.

It's hard to imagine how defensive the suit would be if you could use these unknown metals to make a full suit.

Just when Li Feng was ready to continue to think about more ways to crack it.

Suddenly, a message came from Qili's side, which made him stop the pointless attempt to continue.

"What, you found the fifth type of snake?"

This news stunned Li Feng for a moment, when he rushed to the General Institute of Biology in the shelter.

Sure enough, a small black Teng snake was kept in a closed transparent secret room and observed.

"Are you sure it's a snake?" Li Feng looked at the tempered glass for a while. Some were unsure.

The black-skinned little Teng snake in front of him, just from its appearance, it basically does not have much resemblance to the Teng snake race.

Instead of a teng snake, why don't you call it a scorpion snake?

Because it has the head of a snake and the tail of a snake, but the upper body is unusually strong. Even if it had only been born for a short time, its upper part was not only extremely strong, but also wrapped in a thick circle of black scale armor.

Overall, this little snake looked like it was wearing a thick black armor.

To describe it from another side, this is a Teng snake and scorpion body creature, but the most amazing thing is that this little Teng snake is even more complete than the Teng Snake Emperor that Li Feng had raised as a demon before.

Because it not only has a pair of strong calves, but also on the sides of the upper body cavity and abdomen. But it has the sturdy short limbs and sharp claws of a pair of lizards.

"It's the Teng Snake That's right, this is the logistics staff who attacked the Ghost Domain last time, and they got it back from cleaning the battlefield, a total of five Teng Snake eggs, and the other four are very normal, and the corresponding ones hatched out are two Wind Teng Snakes, a Fire Teng Snake, and a Poisonous Teng Snake. But this one is very special, boss, you see ......"

With Qili clapping her palms. In a closed room, a nest of rats was suddenly put in.

As soon as these rats were put into the breeding room, their natural instinctive instinct felt the dangerous aura of the little Teng snake, and they were so frightened that they hugged their heads and ran around.

However, at this time, this mutated little Teng snake, which had just been born for a short time, moved.

I saw it raise its head and let out a shrill sound. Then Li Feng only felt that there was a flower in front of him, and there was about a series of black shadows, which flashed quickly.

When he saw the situation in the breeding room again, he was stunned.

This nest of rats scurrying around in a panic fell to the ground. Only the occasional trembling limbs and feet proved that they were still alive a moment ago.

"Dead!?"

After a few seconds, even his limbs no longer moved, and he was completely dead.

But with Li Feng's current strong reflexes, he didn't see clearly how this litter of rats died.

The only reason he could deduce was probably because the series of black shadows sent out by the little Teng snake just now had something to do with it.

What exactly is this attack?

It's too fast, and this is the attack of a small Teng snake that has just hatched from the egg for a few days?

"Isn't it scary?" Qili looked at the boss and was stunned, and couldn't help but smile and ask.

"Well, where did this little pervert come from?" Li Feng said subconsciously.

"It's all said, it's the Teng Snake Egg hatching, but it's very special, and our logistics staff have not brought back the Teng Snake Egg, trying to train it from a young age, so we got a lot of Teng Snake Egg, but it is unique among thousands." Qili rolled her eyes and said.

"What the hell is the black shadow that shot out just now?" Li Feng nodded.

Although he was quite surprised, in essence, Li Feng didn't feel much threat from those black shadow attacks.

This instinctive instinct could tell him that with his current defensive ability, whether it was the Silver Armor from the Corpse King or the Imprisoned Spirit Wall, he would be able to resist these Black Shadow attacks.

"I don't know exactly what it is, just look at this."

Soon, Qili asked her female assistant to broadcast a slow motion on the screen, which was the moment when a nest of mice was put into the breeding house, and then the little Teng snake launched a sharp moment.

Finally, when the screaming was about to stop, Li Feng finally caught what the previous black shadow was from the slow mirror.

It turned out to be one black thorn after another, but their eruption speed was so fast that Li Feng couldn't catch the shadow.

The little teng snake squirted out a total of seven black thorn spikes in the spurt, and struck the panicked rats into the nails.

The whole process took less than a second, and everything happened, so fast that the rats didn't even dodge, but even the reaction had just happened.

Fast, accurate, ruthless.

After watching the slow mirror only once, Li Feng really didn't know what words to use to express the vibration in his heart at this time, except for using these three words to describe it.

As a human powerhouse with a nine-fold physique, Li Feng understood very well how terrifying the shooting was at that moment just now.

This is simply more terrifying than the best black-scaled sniper under his seat.

And they shoot seven spikes in a row, and the sniper can only shoot once and aim again.

How big is the gap between the two? Go without saying.

Could it be that this little Teng snake is inherently far more powerful than the motion capture of the black-scaled man?

Oh, my God.

Li Feng carefully measured himself, but it didn't take long for him to realize that even with his current strength, he couldn't dodge the attacks of these black thorns, so the look in his eyes when he looked at Xiao Teng Snake again was already very different.

"Boss, although I know you're surprised now, this kind of motion capture superpower is actually not the reason why I bother you to drive, you can take a look at this discovery again, it's really amazing."

Qili suddenly asked her assistant to play another collected clip, and she knew that this discovery would definitely surprise Li Feng. (To be continued......)
