Fifty meters deep underground.

This is a desperate depth, and even professional drilling equipment may not be able to dig into such a deep ground in a short period of time.

Moreover, this underground is also a nest of mutant ants, if Ning Feng and the others dig the land too much, it is likely to alarm the queen ant to continue to escape, and I am afraid it will be even more difficult to kill this queen ant at that time.

Once the queen successfully escapes, then everyone's efforts on this trip will be completely in vain.

Because, as long as the queen is alive, it can give birth to a new colony.

Immediately, Ning Feng also looked at Cheng Yanjin and asked quite solemnly: "Old Cheng, can you split the ground fifty meters deep?" ”

Cheng Yanjin replied confidently: "No problem! ”

For Cheng Biting Jin's self-confidence, Ning Feng naturally trusted him very much, and immediately said: "Old Cheng, you can completely split the ground according to the position indicated by Zhang Yue!" ”

Cheng Yanjin nodded, immediately held his breath, contracted his muscles, and gathered the double axes in his hands above his head.

"The righteous impact of the axe of love!"

I heard Cheng Biting Jin let out a loud shout, and saw him swing the double axe in his hand downward, slashing towards the ground fiercely.

As the double axes slashed on the ground, the entire ground trembled instantly, so that Ning Feng and Zhang Yue were a little unsteady on their feet.

And the ground under the feet of the three of them also began to crumble and split, and a dark and deep ravine quickly formed, just like Cheng Biting Jin with an axe, opening a small wound to the earth.

"Look! That's the queen ant! ”

As the ground was split open by Cheng Biting Jin, Zhang Yue was extremely shocked at the same time, but she also saw the queen ant under the ravine, and immediately couldn't help but point at the queen ant and shouted.

I saw that the appearance of this ant colony queen was almost no different from other ordinary mutant ants, but its size was dozens of times larger, similar to the carriage of a train.

In addition, the queen's body surface also exudes a jade-like luster, which actually looks a little evil and abnormal.

Seeing that the ground was directly split, the queen ant hiding underground was also instantly startled, and actually trembled twice in a panic.

Then, the queen ant hurriedly waved the tentacles on her head to transmit the guard signal to the surrounding ant colony.

In an instant, the ant colonies above and below were all crazy, attacking Ning Feng and the three of them desperately, wanting to use their lives to defend the safety of the queen ant.

"Heat Boom!"

In the face of the desperate attack of the ant colony, Cheng Yanjin directly launched his skills, turned the double axe in his hand to rotate and attack, and actually created a blade cyclone in the entire industrial park.

Under the cutting of the axe blade cyclone, thousands of mutant ants were instantly wrenched into pieces, leaving only countless remnants scattered on the ground.

"Lao Cheng! Leave these ordinary ants alone, the most important thing is to kill the queen ant! Ning Feng said to Cheng Yanjin.

Cheng Yanjin also nodded, and immediately ignored the ants attacking around, but jumped directly into the ravine.

Although this queen ant is huge, her attack power and action are short, so after seeing Cheng Biting Jin approaching her, the queen ant was suddenly frightened and wanted to hide.

However, in front of Cheng Biting Jin's bursting double axe, where does this queen ant have a place to hide?

I saw Cheng Biting Jin ruthlessly wielding a double axe, slashing back and forth on the queen's huge body, instantly making the queen full of scars left by the axe blade.

If it weren't for the queen's body covered with an inky jade-colored shell, I'm afraid it would have been dismantled by Cheng Jin.

And under Cheng Biting Jin's chopping, the queen ant also felt severe pain, and couldn't help shaking her body in more pain.

Seeing that the queen ant was worried about her life, all the mutant ants panicked and gathered towards the queen one after another, using their bodies to block the axe chopping for the queen.

However, even if the mutant ants resisted desperately one after another, it was difficult to stop Cheng Biting Jin's fierce offensive.

At this time, Cheng Yanjin was also playful, and he was not in a hurry to kill the ant queen, but slowly cleaned up the ant colony.

Soon, all the mutant ants were killed, so that the entire ravine was filled with the corpses of the mutant ants.

"Lao Cheng, stop playing, let's end the battle quickly!" At this time, Ning Feng saw that the ant colony had been emptied, so he shouted at Cheng Yanjin under the ravine.

Hearing Ning Feng's slightly impatient voice, Cheng Yanjin didn't hesitate anymore, and immediately held the double axe again and slowly approached the queen ant.

Looking at Cheng Biting Jin, who was approaching, the queen ant also fell into complete despair, and it felt that it was getting closer and closer to death.

Just as the queen ant was about to die, the queen suddenly raised her tail and pointed the tip of her tail to the sky.

Immediately, a green, fishy liquid squirted out from the tip of the queen's tail.

In an instant, the entire industrial park was covered with green rain.

As the green liquid landed on his body, Ning Feng felt a tingling sensation coming.

Immediately, Ning Feng couldn't help but look down, but saw that the skin where the liquid was dripping was actually corroded into a small gap.

"Not good! This is the formic acid in the queen's body, and it is hugely corrosive! Ning Feng exclaimed in shock.

"Ahh

At this time, Zhang Yue, who was beside Ning Feng, also let out a miserable howl because of the pain caused by the corrosion of formic acid.

Seeing this situation, Ning Feng didn't say a word, and directly picked up Zhang Yue and took refuge in the buildings in the park.

On the way to the building, Ning Feng used his body as a cover to help Zhang Yue cover the splash of formic acid.

Soon, Ning Feng fled into the building with Zhang Yue, but Ning Feng's entire back had also become a blur of flesh and blood, and it was actually corroded by formic acid.

"Ning Feng, your back ......" Zhang Yue also noticed Ning Feng's back, but she couldn't help covering her mouth, and said with her eyes wide in shock.

However, Ning Feng didn't care about the injury on his back, and said as usual: "It's just a small injury, it's not a big deal." ”

After all, for Ning Feng himself, he had already experienced more serious injuries, and this injury was nothing at all.

Besides, he Ning Feng also has the skill "Holy Light Guardian", and these injuries will recover quickly.

However, Zhang Yue didn't know about Ning Feng's situation, but Ning Feng was worthy of being an iron-clad fierce man.

At this time, Ning Feng didn't care about Zhang Yue's opinion, but he focused all his attention on the ravine outside, because he was a little worried about Cheng Biting Jin's situation.

……

As Ning Feng expected, the corrosive formic acid sprayed by the queen ant put Cheng Yanjin in trouble.

Now, the entire ravine has been filled with formic acid.

Although these formic acids cannot hurt Cheng Biting Gold, they can corrode the ant carcasses in the ravines and dissolve the carcasses into soft flesh and mud.

Moreover, there is a lot of organic matter in the ground, all of which are food stored by the ant colony, and when these organic matter are contaminated with formic acid, they will also be dissolved into soft meat puree.

Therefore, the ravine that Cheng Yanjin split became a deep pool filled with meat and mud, which made him stuck in the quagmire and unable to extricate himself.
