Let's start by analyzing the sun

From the moment Cheng Han asked, "Interested in working with me?", the others really had no choice.

Du Shancheng, the vice centurion of the First Battle Group, was the first to shout, "Cheng Han, our battle group will work with you!"

If they refused, it would mean they wouldn't be able to enjoy Cheng Han's secret techniques, and as a result, the battle group's performance would inevitably be far behind.

The others naturally understood this reasoning and expressed their positions one after another.

"Cheng Han, the Third Battle Group is in too!"

"Count the Fifth Battle Group in!"

Tie Feng, the vice centurion of the Second Battle Group, sighed silently, acquiescing to the current situation.

There was nothing he could do.

After all, the Second Battle Group couldn't possibly have internal strife in front of so many people, right?

Besides, if they really won the fastest clearing honor, then the battle merits obtained by the Second Battle Group would be unimaginably rich, worth a try!

Thus,

the five battle groups reached an agreement.

Cheng Han transformed into the leader of this mission.

Du Shancheng approached, his tone faintly suggesting a request for instructions: "Cheng Han, shall we start exterminating the void insects now?"

Cheng Han thought for a moment and said, "Let me add another layer of protection for everyone."

He took out another black seed from the flower basket and threw it to his own vice centurion, Tie Feng: "Activate it with your mental power."

Tie Feng was a little dazed, but he did as he was told and began to input mental power into the seed.

The others turned on spectator mode.

Everyone was curious about the endless stream of methods of this genius teenager.

"Poof!"

A soft sound was heard.

The black seed exploded.

Thousands of thin black vines suddenly burst out and rushed towards Tie Feng from all directions.

Tie Feng's face twitched, and he instinctively had an urge to dodge, but he thought that Cheng Han would not harm him, and he forcibly suppressed the impulse.

In an instant,

the vines attached to Tie Feng's black armor, forming a layer of densely woven vine armor on its surface.

Tie Feng glanced down and said with a slightly surprised tone, "It's quite good-looking!"

Everyone nodded.

A mere seed could transform into a set of armor that looked quite protective. This method was indeed extraordinary.

The corner of Cheng Han's mouth twitched.

The methods I researched only earned a "quite good-looking" evaluation? Forget it, let you see it for real.

He looked at Du Shancheng and shouted, "Punch Tie Feng!"

Tie Feng's old face twitched again upon hearing this.

What the hell?

Du Shancheng's face lit up, and he decisively punched Tie Feng.

"Whoosh!"

The wind from the fist howled, showing how powerful this punch was.

If he was hit by this punch, he would definitely not have a good outcome.

Just then,

the vine armor on Tie Feng's body suddenly surged with a large number of vines, some forming a buffer layer to block in front of the fist, and others attacking Du Shancheng.

Du Shancheng was taken aback and quickly retracted his fist and took a few steps back.

The vines automatically retracted and returned to the vine armor.

Everyone was dumbfounded.

My God!

This armor can automatically counterattack? What kind of awesome gameplay is this?

Cheng Han then explained, "The vine armor can withstand several close-range attacks. In an emergency, it may save your lives."

Tie Feng touched the armor, convinced: "Several people in this team have mastered the Qingyuan Rune Seal, but only you have played the rune seal to the fullest."

No one objected to this.

Because it was indeed the case.

Cheng Han began to distribute the seeds: "Everyone, receive a seed each. If the vine armor is gone, come to me to receive it again."

Everyone was very active and activated the seeds after receiving them.

After all, the previous experiment proved that this was a good thing that could really save lives, and no one was foolish enough to refuse it.

Soon,

the warriors, in small teams, dispersed into the crisscrossing passages and began to carefully search for the traces of the void insects.

The mission officially began.

*

Five minutes later.

The first battle broke out.

"Woo~"

A sharp scream of a short spear suddenly broke the silence in the Lingye Handle.

Ten seconds later,

two warriors carried over a hideous insect corpse.

Cheng Han saw the void insect with his own eyes for the first time.

This thing was about the size of an adult, and its appearance was similar to a locust in another time and space, except that it had no wings on its back and no ability to fly.

What was impressive was that the head of the void insect was a bit like a human head, with yellow hair scattered on the top of the skull and a pair of emerald green pupils.

This strange feature of "blond hair and blue eyes" made Cheng Han mutter to himself, "Sartre people."

The other parts were more disgusting. The mouth, or rather the mouthparts, opened at an astonishing angle, and the sharp teeth were still covered with wood chips left by gnawing at the Shenrong.

Although the wood in the Lingye Handle was relatively soft, it was only relative, and its hardness was not much worse than that of rock.

And this sharp mouthpart was also the biggest threat of the void insect.

One of the warriors said excitedly, "We deliberately walked twenty meters away before throwing the short spear, and easily killed this void insect.

"It's ridiculous that the void insect thought that its protective color had successfully deceived us, but it didn't know that it was discovered from a long distance away."

Another warrior sincerely said, "The beauty of 'Mind Follows Color' can only be known after experiencing it personally."

The two babbled for a while and went back to work.

Cheng Han took out a magic tool called "Insect Devouring Hook", activated the spirit pattern with his mental power, and waved it lightly at the insect corpse.

"Poof! Poof!"

A large number of brown roots quickly drilled out of the ground, wrapping the insect corpse inside, forming a ball.

The effect of the Insect Devouring Hook was to activate the Shenrong's swallowing mechanism, so that it could recycle and utilize the energy in the insect corpse.

Shenrong could also use this to record how many void insects the Black Armor Army had killed, and Xuangong could extract relevant information to judge whether the subordinate small spirit realms were working hard.

By the way.

In this cleaning mission, Cheng Han didn't need to kill insects himself.

His job was two things, one was to constantly use secret techniques to help everyone find void insects, and the other was to dispose of corpses.

A dozen seconds later.

The roots retracted.

There was nothing left in place.

The insect corpse was gone.

Cheng Han put away the Insect Devouring Hook and muttered, "Really interesting."

The Shenrong's efficient absorption of energy taught him a lot.

*

As the battle groups advanced, they continued to discover void insects. The sound of short spears whistling rose and fell, and more and more insect corpses were sent over.

Cheng Han became slightly busier.

However, compared to others, he was still very idle, and he even had a lot of leisure to play tricks.

For example.

After a while.

Two other warriors each sent over an insect corpse.

They witnessed with their own eyes that Cheng Han did not use the Insect Devouring Hook at all, but just snapped his fingers, and a large number of roots rose from the ground and submerged the insect corpse.

Cheng Han glanced at the two people's surprised eyes and explained, "The method of the Insect Devouring Hook communicating with the Shenrong is very easy to simulate with the Qingyuan Rune Seal."

The two warriors looked at each other, and their hearts were full of admiration.

Is it really easy to simulate?

Not necessarily!

Otherwise, why has no one else done it for so many years?

For example:

Cheng Han found a succulent that glows at night, urged a few seeds, crushed one of them, and countless dust floated out.

Only half a breath later.

The passage changed to a new world - everything became fluorescent, every cave wall, every spiral column, was shining brightly.

Where had the warriors ever seen such a magical scene, and they all exclaimed in surprise.

Cheng Han smiled with satisfaction and muttered, "Compared to the other two rune seals I have learned, the Qingyuan Rune Seal is much more interesting."

Soon.

The warriors discovered that the genius teenager was not just playing.

All the void insects in the fluorescent area were in a strange state. They seemed to have become blind people who could not see, and after hearing the footsteps of the warriors, they would only run around like headless flies.

Du Shancheng, the vice centurion of the First Battle Group, took the opportunity to deliver the corpse and asked curiously, "Why did the insects become like this?"

Cheng Han casually replied, "The reason why void insects have night vision ability is because they eat some luminous plants every day. By using this point, their vision can be interfered with."

Du Shancheng was slightly surprised: "I see."

Cheng Han smiled: "Knowledge is also combat power."

Du Shancheng was thoughtful.

After this guy went back, he sighed: "I understand, Cheng Han can flexibly use the knowledge he has learned to play the Qingyuan Rune Seal in various ways."

Du Shancheng looked at a senior team leader: "Lao Niu, you have mastered the Qingyuan Rune Seal, I think you can also develop some novel abilities like Cheng Han."

Lao Niu had a wooden old face: "Knowing and doing are two different things."

Du Shancheng was puzzled: "Why? I think Cheng Han seemed to do it very easily."

Lao Niu was a little embarrassed and annoyed: "I saw Cheng Han sitting in the stele valley for a day and easily comprehending the Qingyuan Rune Seal, why can't you comprehend it?"

Du Shancheng was choked.

Lao Niu said angrily: "A sentence 'learn from luminous plants' is easy to say, do you know how many difficulties there are in it?"

This guy asked a series of questions aggressively: "How do void insects absorb luminous elements? How do they use it to transform their vision? How exactly should luminous light be used to interfere with the vision of void insects?

"I just listed a few casually, and I thought of a dozen questions. I'll give you a day, can you answer one of them?"

Du Shancheng opened his mouth, but in the end he didn't say the sentence "I saw Cheng Han researching it very easily."

*

An hour later.

Tie Feng personally carried two insect corpses over.

After this guy watched the insect corpses being disposed of, he couldn't help but ask: "So far, how many void insects have the five battle groups hunted in total?"

Cheng Han reported a data: "Fifty-eight."

Tie Feng was surprised: "So many have been killed in just two hours?"

Cheng Han blinked: "Is it a lot?"

He felt in his heart that the efficiency of these people was really not high. If he went all out himself, he could kill two hundred in two hours.

Tie Feng asked: "Do you know how many insects can be killed at most in a day when doing the task of clearing void insects in the past?"

Cheng Han shook his head.

Tie Feng cursed: "At most, it's only one hundred and fifty, today, according to your method, two hours is equivalent to half a day in the past."

Cheng Han endured and endured, and swallowed back the words "the previous teams were so weak".

Tie Feng was very excited: "According to your method, it seems that the Tai'an Small Spirit Realm has a great chance to win the first place."

Cheng Han nodded lightly, and muttered in his heart: If the other small spirit realms are also so useless, then there will definitely be no problem in taking the first place this time.

*

Another hour passed.

The number of insect corpses sent over by everyone has obviously decreased a lot.

Cheng Han carefully sensed the distant movements and issued a timely warning: "Everyone be careful, the insect swarm has sensed the danger and has gathered together. Warrior-level void insects will appear in front!"

Thank you to the big boss "Gu God" for the reward!
