On this day, the lively Red Light City became different.

First of all, a beam of light about one meter was divided into a solid red star light column with a diameter of only ten meters. It passed through the frozen air prism in the air and scattered into the shape of a trumpet cover, completely covering the canopy layer of the small world tree that was pushed to the dome of the underground world.

Those dark green leaves tend to turn black and almost completely absorb the light. The faint reflectivity makes their color approach gray-green. Without careful observation, the veins of the leaves cannot be identified.

Secondly, there is the "giant whale corridor" in the air. New tree roots are growing, and a small vine passage with a diameter of more than 20 meters is woven to connect to the middle of the trunk of the small world tree. It is like a temporary small interface being opened on a huge pipeline, and the surging giant whale frozen gas energy passes through this "small world tree corridor" and continuously transmits towards the trunk.

Finally, it is near the roots of the small world tree. A huge tree root of the new world tree must break through the ground, and pierces into the main trunk like a sharp blade with light green fluorescence. The two do not merge with each other, and silver-white substances overflow in the place where they come into contact, condensed into a layer of current insulation, completely isolating the two.

It is an ultimate metal material with a thickness of half a meter. The surgeon who goes to observe can recognize the material at a glance.

The access point of this tree root is Cassia's body. The world core, which has about 70% of its efficacy, emits light blue light, has begun to convert and safely transmit resources such as the ultimate metal components and perfect evolutionary substances provided by Miss Rebirth World Tree.

The small world tree next to the drilling hole has also changed. In the past, it was just an ancient tree that looked extremely huge, and the breath of life it emitted makes people feel comfortable. Now, in addition to the stronger breath of life, which makes the air in the entire Red Light City much fresher, it has also become a tree-shaped lighthouse with light green lines crawling over the main trunk, but the light emitted can bring warm cold white.

Shortly after these changes occurred, the notification that "no need to care about changes, everything goes according to normal conditions" was known to all surgeons in the underground world.

But among the many members, a small number of members ushered in a carnival. They all have the same characteristics, all of whom are surgeons at more than five stages. And the stronger the strength, the closer they are to the late stage of the five stages, or transition to the extreme field, it means that the carnival will become stronger.

Who realized it first? It was no longer clear. In short, when the sentence "Casia came here, Millen and Lissuman went to the main trunk of the Little World Tree to perform another mission, which would not appear for at least two months" was spread, they realized that the changes in Red Light City were closely related to themselves-

"...Lisuman went to the trunk of the Little World Tree to perform another mission, and it would not appear for at least two months." The words spread out finally changed. But it has to be admitted that for high-level surgeons in the entire underground world, it is the focus.

However, after only half a day, when the machine was installed and one-third of the pollution purification factory completed commissioning began to operate, and the purification pollution gradually spread to the entire Red Light City, all surgeons had to pay attention to it.

This is a reward for them, and it is the reward for performing mining tasks. Although the amount of purifying pollution can only be regarded as rare, both low-level surgeons and high-level surgeons can indeed benefit from it.

However, apart from the changes that can be seen and felt by members of the Red Light City, in the canopy of the New World Tree unfolding in the starry sky, another "Casia" broke through the bark and stood on a branch that could fully bathe in the red starlight in the starry sky.

He was like a magnet, with attractiveness since he was "born". The red star light in the starry sky was pulled actively and gathered towards him. It was soon submerged in the brighter red light, until with a "bang", a large tent of flames rose and burned vigorously.

"Successfully ignited." Although the body is in the stars, the conversation between the two is in the trunk of the small world tree in the underground world.

"When I went to the vortex of Polar Sea with Mr. Manicoloa, I have tried many ignitions and maintaining combustion." Cassia replied confidently, "After that, please maintain the energy supply to the 'recruiting the red star's will. The consciousness body will not always be here, so I need other maintainers."

After pausing, he continued, "The increase in the intensity of the red star's light is indeed a huge problem. Although this moment has long been expected to come,..."

With a sigh, he sighed, "But, I handed this question over to myself in the future. Of course, that 'the self in the future' is my current me..."

"But now, I still haven't found a good solution. The restrictions on the Small World Tree Planting Plan are too huge."

"When the distance is closer, maybe with the inductive connection between you and Red Star, you will have an answer after obtaining more information."

Cassia used this sentence as a comfort to Miss New World Tree, "Thank you. Unfortunately, at this point in time, I can no longer throw the problem to myself in the future."

As he said that, he was silent for a while, then he spoke, "Murun and Lisuman are ready for the final preparations, let's start now."

At the same time, in the starry sky, in the main trunk of the small world tree, under the ground, and the extremely deep underground, all movements are completely synchronized with Cassia as the connection point.

A large amount of pollution was released from the rhizomes of the ancient historical world tree. It was conducted by the small world tree and came to the trunk, purified by the core of Cassia's world, and then supplied.

Millen and Lissuman absorbed the purified pollution, replenished the various material resources provided by Miss New World Tree at any time, and began to accelerate their progress on the evolutionary route.

Two days later, after the cycle stabilized and there was no problem with the purification of pollution, Cassia set up safety protection measures to prevent the spread of the rich pollution to the entire Red Light City due to the out-of-control purification. Then hello to Miss Xinsheng World Tree, and the consciousness disappeared immediately.

In a short while, perhaps just a few breaths to find the anchor. When the Cassia consciousness appeared again, it was already on the vast sea.

Below, a super-large island-like white iceberg is nailed in the sea, and the surging energy is always emitting towards the sky, and is transmitted to the three-phase continent through the snow clouds.

"This is the cluster grave." Cassia sighed. Without careful observation, he realized what the essence of the cluster grave was.
Chapter completed!
