In the previous preparation stage, after Ye Feng got Zhao Zhenyuan's authorization, he went to the research institute of the Chinese Academy of Sciences and swept many good things inside, and the miniature ground-drilling bomb in his hand was one of the items.

Looking at the miniature earth-drilling bullet in his hand like a toy, Ye Feng still remembered that the staff member told him that the cost of this thing was more than ten times that of a real ground-drilling bullet.

This thing is rarely used, and is usually used by agents, and is only used when striking enemy underground bases.

And the power generated by its built-in helium triple reactor after it is actually activated is definitely not much weaker than that of a real ground-penetrating bomb.

Although it is only 100 meters deep, it is not as good as a real ground-penetrating bomb, but it can easily destroy a 100-square-meter reinforced concrete building.

Thinking of this, Ye Feng no longer hesitated, he immediately jumped off the big tree and jumped onto the ground that had been swept away by the blast wave.

Then it was taken out of the evolution box, a matching miniature launch pad.

This launch pad is more of a large iron drum than a launch pad.

The height of this "iron bucket" is only about half a meter, and the width is 30 centimeters, Ye Feng put the miniature ground-drilling bomb in his hand into the groove inside, and then locked it, and the ground-drilling bomb and the launch pad were all upside down on the ground.

Then his fingers flick across the trackpad on the side, setting the parameters.

Of course, the parameters set are also very simple, that is, the depth of the drill, and the inclination.

As long as these two parameters are set, the rest will be automatically debugged on the microcomputer.

If you're attacking a normal ground building, it's going to be a lot easier, because it's not hard to enter two parameters.

But at this time, what Ye Feng was attacking was a mutant zombie king who was constantly moving, and the difficulty of this was not half a star.

If it weren't for the fact that the mutant zombie king was seriously injured, and the consumption was huge, and he was moving slowly under the land, Ye Feng would probably have to give up directly and use the ground drilling bullet to strike.

But even so, you can imagine how difficult it is to do so.

Ye Feng's fourth-order spiritual power could be said to be unreserved at this moment, rushing directly towards the ground, carefully sensing the aura on the mutant zombie king's body.

At the same time, he also made subtle adjustments to the parameters, such as the angle and depth of the inclination of the ground-drilling bomb.

Although the explosion range of this ground-penetrating bomb can cover a full 100 square meters, the real damage can only be caused by 10 meters of the core range.

Therefore, Ye Feng had to control the ground-piercing bomb and explode within ten meters of the mutant zombie king's body, which was definitely not an easy task.

After the spiritual power gushed out without reservation, the breath of the mutant zombie king gradually became clear in Ye Feng's perception.

However, clarity alone is not enough, what Ye Feng needs is complete precision, so at this moment, after the spiritual power is running to the extreme, it directly enters an ethereal state.

This is a terrifying ability that is naturally born after the spiritual power reaches the limit of the human body.

After entering the ethereal state, the whole world slowed down, and after the spiritual power broke through the fourth order to complete the qualitative change, this was the first time that Ye Feng entered the ethereal state.

At this time, in Ye Feng's entire world, in addition to being extremely clear, it is also as if he can see through, and he can directly "see" the scenery behind an object.

And when his gaze moved downward, Ye Feng could also "see" the mutant zombie king underground, constantly going down.

At this time, Ye Feng's eyes were of course unable to see through, but the spiritual power in his mind was like a radio at this time, constantly radiating towards the surroundings at an ultra-high frequency.

And the things that are observed will be presented in Ye Feng's mind in a three-dimensional form, to use a more popular metaphor, Ye Feng at this time is like a humanoid radar.

Under this kind of exploration, everything within a hundred meters of Ye Feng's body could not be hidden.

Of course, if the spiritual power goes underground, it will still be weakened to a certain extent.

For example, Ye Feng can only detect things within 50 meters below the ground now.

But all this was enough for Ye Feng, at the same moment when he saw the mutant zombie king, Ye Feng's spiritual power had already locked on the other party, and his fingers quickly entered a series of parameters on the touch screen in front of him.

"8% inclination and 15 meters depth."

After entering, Ye Feng directly slapped the launch button in front of him.

Sou!

Originally fixed on the launch pad, the miniature earth-penetrating bomb like a toy exploded with terrifying energy at this moment, and the tail jet erupted with a blazing tail flame, pushing the ground-penetrating bomb forward.

The borehole at the top was spinning rapidly, the earth was broken in an instant, and the entire ground-penetrating bomb was drilling downwards at an extremely terrifying speed.

Ye Feng watched the micro ground-drilling bomb in front of him successfully launch, and sat down on the ground with a buttocks.

Now that he has suffered a lot of trauma on his body, and the true qi in his body has been exhausted, coupled with the ethereal state he has just exerted, his spiritual power has almost been drained, and at this time, his combat power can be said to be one in ten.

If that doesn't kill the Mutant Zombie King, then he's gone.

After sitting on the ground, Ye Feng was indifferent to the zombies that came up around him, and he was just secretly counting down in his heart.

When he counted to the fifth second in his heart, he suddenly felt that under the ground, there was a breath that made Ye Feng feel palpitations, and he suddenly rushed upward.

A bad premonition came to my mind.

The next moment, a scene that made Ye Feng's eyes widen appeared, and the dirt more than 50 meters in front of him was like a bubble, directly bulging, and then bursting open.

As this "soil bubble" with a diameter of more than 50 meters bursts, countless pieces of soil fly into the sky, and the surrounding land is like waves, squeezing in all directions layer by layer, forming a crater.

As for Ye Feng, who was in this crater, of course, he was thrown out again, and his legs were almost broken by the huge force coming from the ground.

Having never felt the power of a ground-penetrating bullet, he realized for the first time that this kind of thing was so terrifying.

Ahem, ahem!

Ye Feng, who was thrown out more than 20 meters again, coughed violently after stabilizing his body, and blood spilled from the corners of his mouth.

"These things made by the Chinese Academy of Sciences are really perverted, and I won't dare to use them casually next time." Ye Feng said with a wry smile as he straightened his misaligned left calf. At this time, he was absolutely miserable, and now it has become difficult to even walk.

However, Ye Feng's mood was very good, because the breath under the ground had disappeared into the senses.

Obviously, the mutant zombie king finally died under the miniature ground-drilling bomb, the crystallized technology of the human race.
