Steel steam and flame

In the channel created by melting the rock formations with the breath, the air remains high and has not completely cooled down. The further forward and closer to the underground world, the fainter the light becomes, until it almost disappears completely.

The smell of pollution has been completely dissipated under the influence of Monikoloa's breath and Cassia's blood, but it still remains. The pollution will not disappear, and the passage is built on the underground world. Unless the entire underground world can be completely purified, a lot of pollution will still seep out slowly over time.

Li Suman is not worried. Dealing with pollution is part of the excavation plan. As the excavation depth gradually deepens, more and more professionals will arrive to provide professional opinions after on-site surveys. The quality of the environment in the underground world means whether professionals can arrive safely and stay in the underground world safely for a period of time.

The growing vines of the New World Tree are still accelerating to cover the passage, hoping that the environment will be improved as soon as possible, at least the rock walls of the passage and the air inside will no longer be in a high temperature state.

Li Suman and the dragon continued downward, and the surroundings were dark. The exit of the passage diagonally above their heads had become smaller, no longer as wide and huge as it had been not long ago. Mental perception begins to be disturbed and effects diminish. The bioelectric induction force field was mobilized, and a point of light emitting extremely penetrating white light rose from Li Suman's fingertips, went to the sky above the giant dragon, and moved with it.

The rock wall in the distance was illuminated, and the temperature of the high-temperature air suddenly dropped a lot under the penetration of white light.

"The power of the giant whale group has always made us feel uncomfortable." The dragon spoke, and the words swayed in the passage, "I never thought that we would have this moment of cooperation with the giant whale group. For a long time It is a hostile relationship. Although they occasionally meet in the endless sea, the power of a single-headed dragon is not enough to shake the giant whale, but it becomes prey. "

"The advantages and strength brought by body size." Li Suman looked forward with the help of white light. It seemed that there was a dim gray wall blocking the other end of the passage.

"It's fair. After all, even if the giant whale group has the Endless Sea, it can't match the number of dragons at all." The giant dragon said with a smile, and also noticed the strangeness in front of it. It continued, "The underground world is destroyed by the World Tree. Wrapped in a network of roots, they should be the ones in front.”

The increase in flight speed caused the pale gray walls to quickly solidify, revealing countless intertwined, twisted, and entangled shapes of gray tree roots in the white light. Thin pollution is continuously dissipating through the tree roots themselves and through the gaps between the tree roots, and blends into the air in the channel.

"The next step won't be to dig out this wall made of roots, right?" The dragon suddenly asked, his tone becoming uncomfortable. Living on the island in the sky of the newly born World Tree all year round, no living body can understand the tenacity of the World Tree better than them.

The breath that melts rocks cannot ablate it, and the sharp claws that can cut off the hard bones of prey cannot tear it apart. The methods that were powerful in other places were all passively reduced by one level in front of the World Tree.

Lisuman activated the light spot, which flickered like a leap. She stood close to the rhizome wall and burst out several times more light than before. Some of the thin pollution was frozen, and the rhizome wall in her field of vision became clearer. Just to the side of the two, a hole with a diameter of several hundred meters appeared, with strong pollution coming out.

Amid the sound of friction, a ferocious gray-white pollution-species head suddenly popped up and looked in the direction of the two.

"Ah..." Lisuman sighed feebly, and the light spot jumped to the top of the hole according to her mood, freezing the polluted creature with half of its body exposed.

There was a clear cracking sound, and the flesh and blood turned into ice cubes fell towards the underground world. Li Suman was helpless and sighed, "With the respected Miss New World Tree here, the rhizome wall will definitely be untied very smoothly. Someone will complete a very professional job, but it will definitely not be us."

The giant dragon breathed a sigh of relief. When it responded, a large area of ​​severe cold with freezing energy had already poured into the passage and spread here: "If the underground world directly opens a huge gap in front of it, in about four days, all polluted underground creatures will be destroyed." They will all gather here. Even if we have five giant whales to cooperate, we may not be able to clear them all quickly. "

"Absolutely not." Li Suman emphasized, "There is no specific statistics on how many extreme realm life forms there are in the huge underground world that is similar to the southern forest. What the cleanup team is currently doing is just to open up It’s just a matter of creating a safe path for professionals to get to the excavation site.”

"This tunnel, which allows giant whales to pass through and can refract and transmit the light of the red star, needs additional strength to be better completed." As he spoke, the dragon took Li Suman to the hole in the tree root wall. , the intense pollution has hindered sight and mental perception to varying degrees.

Li Suman wanted to throw a few bottles of blood in to purify this area. Due to the intertwined network of rhizomes, blood was ultimately not used. In addition, the breath of blood may attract powerful underground creatures, like the No. 9 underground creature Cassia encountered not long ago.

"Wait for the passage to be fully established before additional help arrives." Li Suman did not choose to enter the underground world in the end. The work of cleaning up contaminated organisms was too boring, and she wanted to find opportunities to rest as much as possible while working. Moreover, powerful help is already on the way, not far away from here.

At almost the same time, the Empire approached a large city in the Southern Forest.

In the special environment and period, this is already the largest city closest to the Southern Forest. As it approaches the Southern Forest, the cities along the way are taken over by the Empire, the military and the four forces, and are transformed into defensive fortifications. Most ordinary humans have evacuated in an orderly manner and gone to nearby areas.

After eating the not-so-delicious food in a restaurant, Mulun walked quietly on the sidewalk with an ink-colored umbrella. Compared with the Far Sea Common Country, the rain was light, but the air was colder. He raised his umbrella a little and looked to the south-

He thought he could feel the unique atmosphere of the Southern Forest, which was a feeling that he could never experience in the Natural Association Alliance, and a strange feeling that could not be found or explored with the fragments of the ancient historical world tree.

"The Southern Forest and the new world tree are the opportunity for my evolutionary route to move forward again." Mulun's confidence in this idea is increasing rapidly, and he believes that it will be like this. However, he did not think that when he arrived at the Southern Forest, there would be a lot of work waiting for him that Litcia did not mention...
