Steel steam and flame

It was a bright light with an exciting familiarity. Even buried deep under rocks and factory ruins, a bright light bursts out in perception. The fan-shaped tree roots were affected. Without waiting for Mulun's active control, the roots of the tree that were closer to each other accelerated their growth on their own. Like large insects that kept hitting the street lights in the dark, they actively spread towards the light and accelerated.

After noticing it, Mullen immediately intervened and took control. He did not stop the growth of the tree roots, but slowed down the speed, leaving enough distance and space to gain time to react.

The bright light was dazzling, and the heightened perception could not clearly see its true appearance. Things gathered in bright places affect the detection of perception, extremely high energy clusters, or things like pollution that can corrode the spirit itself.

"Pollution of extremely high purity." Then, he made a judgment.

A few memories were awakened, and Mullen immediately responded to what the light represented. Because he had indeed seen the same thing, and his little memory was the only one, and the strange feeling could not be forgotten at all. Moreover, he himself also understood what the memory of that time represented. It was an opportunity that all members of the successor list had been eager to get——

Through Miss Letitia's arrangement, Mullen went to the basement of the association headquarters. Take the elevator directly to the depths of the earth. The exact depth is unknown. According to the body's senses, it is several thousand meters below because the temperature changes from warm to cold, and then from cold to hot.

Finally, when the elevator stopped, a wide platform appeared with some stone tables and chairs. At the edge of the platform is an underground cavity filled with radioactive fluorescence. The air there smells of decay, and unexplained dust fills the entire space, like the air that has not been purified after a fire has been extinguished. Even though he wasn't breathing, he could still feel the uncomfortable feeling of being choked and suffocated in his senses.

The cavity seems to have no end, where perception loses its effectiveness. In other words, after the depth of descent reaches a certain level, the perception will be continuously interfered with, and the range will gradually shrink, until it completely loses its effectiveness after reaching the platform.

He could only see a huge burnt black object falling in front of the endless cavity under the green fluorescence of radiation. Although only a corner was visible, one could still see dozens of huge tree roots twisted together to form a large net, covering the charred black object.

Huge fragments of the ancient historical world tree, as well as the root network of the ancient historical world tree. Mullen knew what was in the cavity, and that was when he felt uncontrollably excited.

Afterwards, according to Miss Letitia's arrangement, he walked forward and soon saw a cave-like tunnel, just above the fragments of the ancient historical World Tree. He walked in without any hesitation, but after entering the cave, he had completely forgotten how far he had walked, how long he had walked, and what he had seen, without leaving any impression.

The only memory that remains is that I didn't know when I opened my eyes, and I was already lying in a bright light. The surroundings are extremely bright, my perception becomes sharper in the world of light, and my body becomes relaxed.

The light was like consciousness, and the body did not reject it. As he continued to absorb the light, Mullen could clearly feel an indescribable sense of comfort. His mind and body were nourished by endless energy, and the perfectly evolved matter almost became a liquid. Soaking himself in it - according to the few reminders before the arrangement, he knew that this was a training, a necessary training to move towards the six stages of life.

It was also because of that training that after Mu Lun woke up, not only was his life evolution path approaching the end, but he was also approaching the end of the five-stage ultimate realm. At the heart he discarded, there was also a fragment of the World Tree with a lot of tree texture.

For some time after cultivating, he still didn't understand what those lights represented. He only knew that the concentration of perfectly evolved substances could be introduced into the body for circulation like blood.

It wasn't until the red star came, the Nature Association opened the entrance to the dragon's nest and the underground world, and the plan to cultivate polluted dragons began to be implemented, that he suddenly understood that the light in his perception was extremely pure pollution, which came from the world tree in ancient history. It is extracted from the root network for absorption and utilization during cultivation.

Later he learned that Thor Vasili of the Theocracy had received the same training at a similar time. Moreover, although it was Miss Letitia and Mr. Nowisas who arranged this training, the actual arranger was the third general under the whirlpool of the extreme sea. Only it can extract extremely pure pollution and provide perfect evolutionary substances in liquid form for use during that period of time to promote the acceleration of the evolutionary path of life.

The original strength was already higher than that of other members of the successor list. After training, Mu Lun felt that the gap in strength could also be widened in the extreme field. Compared with the past, when facing a surgeon in an extreme field, the things that need to be considered are extremely complicated, and in the absence of specific information, caution and information analysis are applied throughout.

After that training, information analysis has not been abandoned, because it is a foundation; and caution is a consciousness that has been deeply ingrained in the spirit since the early stage of the operation. But facing the enemy in the extreme field, he finally felt relaxed, and the danger signals in his body began to gradually become silent after training.

As he got closer to the light, Mulun's mood fluctuated, and various emotions were intertwined in it. There is the excitement of seeing the familiar light again, and the joy of knowing that if I can use this light, I can get a certain improvement. There is also the caution and hesitation brought about by the long-lost perception of danger.

The light itself is extremely pure pollution. During the only cultivation process, the third general extracted it. He knew the meaning behind the light.

The spread of tree roots slowed down again, allowing Mulun more reaction distance and time to move towards the light.

When the light is no longer so dazzling, a "dong-dong" sound appears in the perception. That was a heartbeat. Even though Mullen had already given up on the structure of the heart, his numerous memories still helped him to judge it immediately.

As the distance shrinks, the light shrinks in his perception. For a short period of time, the strong heartbeat caused a vibration in his perception. He finally saw an outline, and more details were revealed in his perception.

",,,"

"The mechanical dragon with the uranium-gold furnace...or, we can call you the ultimate dragon. What the enemy is really creating here is actually you, a mechanical dragon that may be able to catch up with the sixth stage of life. "

While talking to himself, Mu Lun felt the gaze. In the light, the Ultimate Dragon opened his eyes and looked over. However, his vision was not sharp, but rather dull.
