Let's start by analyzing the sun

As Cheng Han was about to reach the door of the mystic vessel's cabin, he suddenly stopped.

The two vice envoys following behind were both taken aback.

Vice Envoy Meng Yi carefully asked, "Envoy, is there something you need…"

He didn't finish his sentence.

This mystic warrior suddenly saw that a spirit oak tree not far away was rapidly growing a new branch, extending directly towards the special envoy.

The new branch was as green as jade, and just looking at it gave one a feeling of vibrant spiritual energy.

In an instant.

This new branch grew to be two meters long.

Then.

Something miraculous happened.

Almost in an extremely short moment, countless emerald green buds sprouted on the surface of the new branch.

Then the buds rapidly swelled into flower buds, and then the flower buds bloomed into flowers.

The new branch instantly transformed into a beautiful flowering branch covered with blossoms, and an incomparably refreshing and peculiar fragrance spread out.

After a while.

The flowers withered rapidly, falling off the branches piece by piece.

The two vice envoys widened their eyes at once.

They saw that mysterious spirit patterns had appeared on the surface of the emerald green branch.

A little bit of strange light was constantly winding and flowing on the surface, adding an extra touch of mystery to it.

It was clear at a glance that this was no ordinary object.

And at this time.

This new branch completed its final transformation, and happened to grow to half a meter in front of Cheng Han, within reach with just a lift of his hand.

Everything was just right.

The other vice envoy, Xiang Wenze, stared blankly for a moment, and blurted out: "This is 'Spirit Swirl Wood'!"

Vice Envoy Meng Yi also looked surprised.

The so-called "Spirit Swirl Wood" is a transcendent material that can be used to make various wood spirit-type mystic devices.

Although this thing is not uncommon, the demand is still quite large relative to the huge group of mystic warriors.

These two mystic warriors could naturally see that this was a gift from each spirit oak tree, each contributing a little bit of tree spirit essence, jointly made to give to the special envoy.

But the problem is that transcendent plants like tree spirits have never been generous.

On the contrary.

These guys are more stingy than the next, it's easy to let them eat, but it's too difficult to get them to spit it out.

But Special Envoy Cheng actually made thousands of spirit oak trees all 'spit' out something, this is simply an unprecedented miracle!

Unbelievable!

Cheng Han smiled slightly and waved his hand towards the forest: "Thank you, everyone!"

He knew very well that the spirit tide time before, and the induction of the power of the Divine Banyan just now, had greatly benefited these tree spirits, which is why they acted like this.

"Whirr ~"

Thousands of spirit oak trees swayed together, setting off a wave.

Cheng Han stretched out his right hand and gently grasped the half-meter-long Spirit Swirl Wood.

Before he could exert any force, he heard a "snap" sound, and the object automatically fell off.

Cheng Han gently weighed the material, and leisurely walked into the cabin door of the mystic vessel.

The two vice envoys exchanged a glance, with a hint of awe, and followed into the mystic vessel.

Cheng Han sat comfortably in the seat, secretly pondering the use of this item.

To be honest.

He possessed the Spirit Mist Myriad Forest Mystic Seal, and the level of this mystic seal was far higher than that of Spirit Swirl Wood, so this thing was not of much use to him.

Cheng Han pondered for a while, and the face of Qian Qingqing flashed in his mind.

He glanced down at the material, and muttered to himself: "It's not bad for making a big spear."

Underground of Heaven Ring B.

Dozens of elite Scarlet Armor Army warriors received an urgent order from above and entered the internal space of the Heaven Ring.

In fact.

Spring is the least suitable season to enter the interior of the Divine Banyan.

Because there are countless luminous plants inside the Divine Banyan, and spring happens to be the breeding season for luminous plants, they will release a large number of spores.

Most spores, when inhaled into the trachea, will produce varying degrees of itching and numbness, and will also cause quite violent coughing.

A few spores are even toxic, and inhaling too much will cause death.

Therefore, neither the Mystic Palace nor the Mystic Pavilion will clean up the Void Insects in the spring for safety reasons.

But now.

In order to conduct an on-site investigation of the changes that have taken place inside the Heaven Ring, this group of warriors, wearing masks that filter spores, ventured deep underground.

All the way along this journey.

The warriors were all quite shocked.

This group of people had all performed the task of cleaning up Void Insects many times in the past, and were quite familiar with the situation inside the Heaven Ring.

But on this trip deep underground, everything the warriors saw completely subverted their understanding.

For example.

The outer layer structure of the cavity inside the Heaven Ring was originally loose and crumbling, almost like a sieve.

Now it has become a honeycomb structure, leaving only a narrow access channel.

Or rather, a wellhead.

And the area above the wellhead is quite open, making it very easy to set up defenses.

The captain leading the team looked excited: "This is a great thing! In the past, some Void Insects would always escape and sneak into the rock cracks above, it was too much effort to search for their whereabouts."

Other warriors echoed one after another.

"Now that the outer layer has become a sealed structure, it won't be so easy for Void Insects to come out!"

"As long as we send a group of people to guard the wellhead, even a group of more than a thousand Void Insects won't be able to rush out!"

At this time.

A warrior suddenly knocked on the honeycomb wall a few times.

"Dong! Dong!"

The sound was quite dull.

This warrior's tone was full of surprise: "This is the harder hardwood inside the Divine Banyan, Void Insects don't like to gnaw on it very much, I remember it used to be softwood."

The so-called "hardwood" and "softwood" are just a kind of oral distinction made by the warriors.

In fact, softwood is not soft at all, even if an ordinary person takes an axe and chops down with all their strength, only a little bit of a mark will be left on the surface.

Other warriors were even more excited.

"It's really much better than before!"

"If we had this thing before, Void Insects wouldn't have repeatedly drilled into the surface, and so many civilians wouldn't have died!"

The captain touched his chin and guessed: "I feel that these changes underground are mainly to prevent Void Insects."

This sentence was met with unanimous approval.

"I agree!"

"I think so too!"

Before long.

The warriors passed through the wellhead and arrived at the central cavity underground of the Heaven Ring.

Everyone was immediately dumbfounded.

As far as the eye could see.

Huge hexagonal spiral structures, like super behemoths, completely penetrated the entire underground space.

Compared with the scattered spiral columns and passages in the past, this scene can be described as art.

The warriors marveled for a while, and soon discovered more benefits.

"The structure here has become too regular, unlike the complex terrain in the past, it is much easier to search for Void Insects."

"The central space of the six spiral giant pillars is a passage, which is also the most convenient place for Void Insects to gnaw, so we can see it at a glance when we enter here in the future!"

"What a pity! If all five Heaven Rings become like this, it will save most of the effort to wipe out Void Insects in the future, the efficiency will be higher, and fewer people will die."

Just as the Scarlet Armor Army warriors were excitedly discussing.

Cheng Han, after half a month, arrived at Jinshan Palace again.

He only waited for less than five minutes before he was summoned by Yun Changtian, the master of the Mystic Palace.

If other mystic warriors were to request an audience with the Palace Master, they would have to wait at least half a day or a day.

Even mystic masters can't see him whenever they want.

And next to Palace Master Yun stood a beautiful woman in a mystic master's black robe.

The latter was none other than Lan Jiayao, the Palace Master of the Heavenly Enlightenment Hall.

Cheng Han respectfully saluted: "Greetings, Palace Master."

He glanced at Lan Jiayao out of the corner of his eye, and muttered to himself.

The purpose of the Palace Master calling me here, could it be related to this Palace Master?
