Poof!

With a dull crashing sound, the strange bone tooth that Sun Feng had pinned great hopes on unceremoniously pierced through a full eighty-seven layers of defense directly under his affectionate gaze.

And the thirteen floors in the back are also damaged to varying degrees.

The last layer, although not pierced, has obvious cracks on it.

Obviously, that ferocious impact, even if it was offset by the previous twelve layers of shields, it would still damage him.

Seeing this situation, Sun Feng didn't know what to say, so he could only be there, touching his head, and smirking like Alzheimer's.

The master of the late stage of the Xuan level, with the strength to eat milk, may not be able to break through the protection, but it was easily pierced by this small bone tooth at the moment.

If you shoot this thing at someone...... Oh ho ho ho ho, that situation must be very beautiful.

Thinking of that beautiful scene, Sun Feng was immediately intoxicated, and he decisively wanted to praise this bone tooth!

Who called this bone tooth now surnamed Sun, it must be the more ferocious the better, if it is harmless to humans and animals, he is not rare.

"The first-level metal essence is so ferocious, what about the second-level one? Try it, be sure to try it! ”

After a smirk, such a thought suddenly flashed in Sun Feng's mind, and when he thought of this, he couldn't help but feel great curiosity in his heart.

Just do it, as soon as this thought emerged, Sun Feng waved his hand and took off the first-level metal essence wrapped in the bone teeth and replaced it with a second-level metal essence.

You must know that compared to the first-level metal essence, this second-level metal essence has a significant improvement in terms of sturdiness. The energy infusion he had received had also changed dramatically.

For example, the first-class metal essence. After one unit of primary energy is infused, the tolerance limit is reached. It melts automatically and is refined.

And this second-level metal essence can withstand at least ten units of primary energy infusion, and only after exceeding this standard will he automatically refine it.

As we all know, the more energy is infused, the faster the speed will be launched, and the more powerful it will be, just like a person throwing a stone. A stone of the same size, thrown by a child, is thrown by an adult, and the distance thrown out is absolutely different, and the power is not the same.

Scientifically speaking, this is the acting force, which is different from the kinetic potential energy.

Basically, Sun Feng put on a holy robe made of second-level metal essence condensed, and that was at speed. In terms of strength, it is definitely ten times that of the first-grade metal essence condensed into the holy clothes, and if you do it, you can pinch the former to death in minutes.

Attack. Defense, speed, are dozens of times the former. How else to play?

Bang!

With a piercing, air-tearing screech. Standing not far in front of Sun Feng, there was a shield condensed by two hundred layers of first-grade metal essence. It was pierced in an instant, and a deep pit was once again opened on the innocent rock wall.

After recalling the bone tooth, Sun Feng found that in the face of this intensity of impact, there was still not the slightest scratch on the bone tooth.

Seeing this, Sun Feng just grinned and secretly praised the ferocity of this bone tooth, and then continued the experiment.

Bang!

Three hundred layers of shields have also been pierced!

Bang!

The shield of the 400th layer was also shattered!

Bang!

The bone tooth is stuck!

Sun Feng experimented again and again, and the number of layers of the shield was also increasing by hundreds of layers, and when he tested it to the fifth hundredth layer of shield, the ferocity of the bone teeth was contained.

"It seems that the bone teeth wrapped in the second-level metal essence can tear through the four hundred and sixty-two layers of shield under the infusion of extreme energy, and the impact force attached to it can also shatter the twenty-four layers behind.

This power seems to be nearly five times more powerful than a first-level metal essence, what if he is replaced with a third-level metal essence? What kind of realm can he be cruel to? ”

Seeing the experimental effect in front of him, Sun Feng suddenly touched his chin and muttered in a low voice, the more he muttered, the brighter his eyes became.

This situation seems to be possible!

Thinking of this, Sun Feng suddenly moved his index finger, and glanced at the superbrain, which had climbed to fifty units of intermediate energy, Sun Feng directly thought in his heart, and drew ten units of intermediate energy from it, which was used to refine the third-level metal essence.

Anyway, most of this energy is used to refine metal essence, condensing the second level is condensing, and condensing the third level is also condensing, anyway, this meat is rotten in the pot, and it can't run away, and it can't fly.

Because of this third-level metal essence, Sun Feng only needed a thin layer to wrap the entire bone tooth and let the energy infusion it bear increase, so he didn't need to consume too much energy.

In addition, when he was in Africa, he also spent a lot of energy to condense a small part of the second-level metal essence, so for this operation, he just had to pay a manual fee, and the materials or something had been prepared in advance.

But even so, after successfully condensing that small handful of third-level metal essence, Sun Feng still consumed a full thirteen units of intermediate-level energy, making Sun Feng's whole person haggard.

"I hope your performance scares the hell out of me, or else, hum ......"

Looking at the strange bone teeth wrapped in a third-level metal essence all over his body, Sun Feng suddenly looked at him with a foul face and threatened him angrily, as soon as he thought of the thirteen units of intermediate energy that he had lost, Sun Feng began to feel congested.

But then, he found out that he was very stupid, stupid and cute, and he actually threatened a broken bone, which is really hehe, hehe, hehehe......

He looked around as if he was a thief, and after finding that his embarrassment just now did not fall into the eyes of the second living creature, Sun Feng breathed a sigh of relief, and there was no need to kill people.

With a wave of his hand again, after repairing the metal shield that was not far in front of him and superimposing it to eight hundred layers, Sun Feng once again began to test the limit of the bone teeth.

Bang!

In the face of the crazy impact of this bone tooth, even if three hundred layers of protective shields were added at once, it was still easily pierced, and at the same time, it was castrated, and a small hole hundreds of meters deep was carved out in the rock wall behind it.

Recall the tooth and continue the superimposed experiment.

Bang!

The nine-hundred-layer shield still didn't stop his ferocity, but the small pit on the rock wall behind him was only more than thirty meters deep.

Bang!

Another extreme shot, the protection of the mille-feuille was also broken, and there was still not the slightest scratch on the bone tooth, just like the paper it had pierced before, just layer by layer of broken paper, not an indestructible metal shield.

But Sun Feng knew that even if it was wrapped in a third-level metal essence, the power of this bone tooth was between a thousand and one thousand layers.

Because of the rock wall behind him, this time there was only a small hole more than ten meters deep.
