Puff!

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

The thirteenth floor behind also has different degrees of damage.

Although the last layer was not penetrated, there were obvious cracks on it.

Obviously, the fierce impact force could still damage him even after passing through the layers of offset by the twelve layers of shields in front.

Seeing this situation, Sun Feng didn't know what to say, so he could only be there, touching his head, and keeping giggling as if he was Alzheimer's.

The late Xuan-level masters who took advantage of their strength to break through the protection, but were easily pierced by this small bone tooth.

If this thing is shot at someone once... Oh ho ho ho ho ho ho, then the situation must be very beautiful.

Thinking of that beautiful scene, Sun Feng was immediately intoxicated and decided to give this bone tooth a thumbs up!

Who said that this bone teeth are already named Sun? It must be the more cruel the better. If humans and animals are harmless, he would not care about it.

"The first-level metal essence is so cruel, what about the second-level one? Try it, you must try it!"

After a silly smile, a thought suddenly flashed through Sun Feng's mind. Thinking of this, a huge curiosity arose in his heart.

He thought of it and did it. As soon as this idea emerged, Sun Feng waved his hand to remove the first-level metal essence wrapped around his bone teeth and replaced it with the second-level metal essence.

You should know that compared with the first level, the second-level metal essence has not only significantly improved in terms of strength, but also greatly changed the energy infusion it has endured.

For example, the first-level metal essence will reach its tolerance limit after infusing a unit of primary energy, and will automatically melt and be refined.

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

As we all know, if the energy infuses is too much, the speed of the launch will be faster. It is also greater, just like a person throws a stone. A stone of the same size will be thrown by a child or thrown by an adult. The distance to throw out is absolutely different, and the power will be different.

Scientifically speaking, this is the difference between force and kinetic potential energy.

Basically, Sun Feng wore a holy garment condensed from level two metal essence. In terms of speed and strength, it was definitely ten times that condensed from level one metal essence into a holy garment. After getting on the stand, he could kill the former in minutes.

Attack, defense, and speed are dozens of times that of the former. How can I play this?

Bang!

With a harsh and sharp whistle, the shield that stood not far in front of Sun Feng, which was condensed with two hundred first-level metal essence, was immediately pierced, 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, there were still no scratches on the bone tooth.

Seeing this, Sun Feng just grinned and secretly praised the cruelty of the bone teeth, and then continued to experiment.

Bang!

The three hundred layers of shield were also penetrated!

Bang!

The four hundred layers of shield was also declared broken!

Bang!

The bone teeth are stuck!

Sun Feng experimented again and again, and the number of layers of the shield was increased by hundreds of layers. When he tried to reach the fifth hundredth layer of the shield, the might of the bone teeth was curbed.

"It seems that the bone teeth wrapped in secondary metal essence can tear apart the 462-layer shield under extreme energy infusion. The attached impact force can also shatter the twenty-four layers behind.

This power seems to be nearly five times stronger than the first-level metal essence. What if he was replaced with the third-level metal essence? What level can he be cruel?"

Seeing the experimental results in front of him, Sun Feng immediately 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 super brain. The intermediate energy that had climbed to fifty units. Sun Feng directly thought and drew out ten units of intermediate energy from it to refine the essence of the third-level metal.

Anyway, most of these energy is used to refine metal essences. The second level of condensed is the same as the third level of condensed is the same. Anyway, the meat is rotten in the pot and cannot be escaped or flew.

Because of these three-level metal essence, Sun Feng only needs a thin layer to wrap the bone teeth and increase the energy infusion it can withstand, so he doesn't need to consume too much energy.

In addition, when he was in Africa, he had consumed a lot of energy and condensed a small part of the second-level metal essence, so he only paid a manual fee for this operation, and the materials and other materials have been prepared in advance.

But even so, after successfully condensing the small handful of third-level metal essence, Sun Feng still consumed thirteen units of intermediate energy, making Sun Feng haggard.

"I hope your performance scares me, otherwise, hum..."

Looking at the strange bone teeth wrapped in third-level metal essence, Sun Feng suddenly looked stinky and threatened him angrily. When he thought of the lost intermediate energy of the thirteen units, Sun Feng began to feel disheartened.

But then, he found that his behavior was very stupid, as if he was naive and cute, and he actually threatened a broken bone. This is really hehe, hehe, hehehe...

After looking around like a thief, he found that his embarrassment just now did not fall into the eyes of the second living creature, Sun Feng then breathed a sigh of relief and no need to kill anyone to silence him.

After waved his hand again, repairing the metal shield that served as a test subject not far away in front of him, and superimposing it to 800 layers, Sun Feng began the limit test of the bone teeth again.

Bang!

Faced with the crazy impact of the bone teeth, even if the shield with three hundred layers of protective shield was added at once, it was easily pierced. At the same time, it was still unabated. A small hole hundreds of meters deep was chiseled on the rock wall behind it.

Recall the bone teeth and continue to superimpose the experiment.

Bang!

The nine hundred-layer shield still did not stop his ferocity, but the small pit on the rock wall behind him was only more than 30 meters deep.

Bang!

Another extreme shooting, the thousand-layer protection was also declared to be broken, and there was still no scratch on the bone tooth, just like the paper that had pierced through before, just like the ones that were broken by layers of poking, rather than the indestructible metal shield.

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

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