At the bottom of the passage, there is a huge secret room of about 10,000 square meters, and in this secret room, the light is very sufficient, because in the middle of the secret room, a huge silver flame is burning.

No one knows why there is such a huge flame in this secret room, and there is no burning material under the flame, but it is a real existence, and the sheep do not need any fuel.

Underneath the silver flames, including the two puppet undead who had turned their heads and fled in earlier, there were a total of four standing underneath the flames.

This time, the puppet undead exuded a strong and surging aura of death, and the four puppet undead blocked Lin Chen in front of them in a fan-shaped shape.

However, at this time, Lin Chen and the others, looking at the silver flame, their eyes were wide-eyed, and their eyes were full of shock, because in the public of the flames, Lin Chen and the others could clearly see a figure, and a figure actually appeared in the flames, and there was no pain.

The silver sè flame was burning, but the temperature in the secret room was not too high, and the figure in the silver sè flame, because it was in the flames, could only barely see a figure, but could not see the detailed facial expression.

It's just that everyone knows that looking at the appearance of these four puppet undead, they are obviously guarding the posture of the figure in the flames, and they know that the figure is definitely not simple, besides, how can the strength of the person who can handle it calmly in the flames be inferior.

"Who the hell is that guy!?" Looking at the figure in the flames, Midalen and Joanke both said with a míhuò and a dignified look.

It's just that although they don't know who the figure in the flame is, Midalen and Joanke can know even with their toes that the figure in the flame is definitely not simple, at least much stronger than these puppet undead of the Nine Grades of the Holy Domain.

"What is this?" However, when Lin Chen carefully looked at the figure in the flames, his eyes suddenly widened.

Because of Lin Chen, he found a lot of things that ordinary people didn't notice, even the supreme-level foundry couldn't notice it, because Lin Chen glanced at Dries without a trace, and even Dries didn't notice it.

"This flame! The temperature in the air does not increase in the slightest! This flame is terrifying..."Looking at the flame with wide eyes, Lin Chen's heart was completely shocked.

Lin Chen has been in this world for so long, and all kinds of powerful flames, even the flames of dragon magic Lin Chen have also seen, but this silver flame, Lin Chen believes that except for the artifact flame in his Qiankun Ding, there is no flame that can compare to this silver flame.

Originally, the stronger the flame, the higher the temperature, and with it, the temperature in the air will naturally increase, just like an erupting active volcano, as long as the flame erupts, I believe that within the surrounding environment for several miles, it will feel unbearable, and even make it difficult for people to survive.

However, the flame of this silver sè was burning, and the temperature of the 10,000-square-meter secret room was as usual.

Why is that? Is it because of the flame of the silver sè, the temperature is not high? No! In fact, the opposite is true, and that is because of the flame of the silver sè, the temperature is too high.

If it weren't for the fact that Lin Chen himself had reached the level of a divine craftsman, and his understanding of flames had reached a very high level, Lin Chen would not have been able to see it.

When the flame burns, why does the surrounding temperature increase? That's because of the heat energy in the flame, that is, the phenomenon of energy flow, but the temperature around the silver flame does not rise, and that is because of the silver flame, the energy is completely controlled.

Even the heat energy does not pass in the slightest, which means that the energy of the flame is all inside, and it is not wasted out of thin air like other flames.

"What a terrible flame! The energy is completely under control! Looking at the silver flame, Lin Chen's heart murmured, of course, what made Lin Chen the most dignified was the figure in the flame.

As the saying goes, if it is a useless piece of scrap iron, as long as it is tempered for a long time, it can become a good piece of steel, and besides, the more powerful the silver flame is, the longer it stays in that flame, the stronger the physique becomes.

If that figure had stayed for a hundred and eighty years, it would have been terrifying, even without the means of a foundry, the power of the flames would be enough to temper the body into a very terrifying one.

"Four puppet undead! I'm holding three back! You can kill one of them in a hurry! Looking at the four puppet undead, Midalen gently stroked the sword of divine power in his hand and whispered to Joanke.

Obviously, the Dragon Scale Armor and the Sword of Divine Power are here, and Midalen is very confident that he will be able to fight the three puppet undead without falling behind.

As for Joanke's strength, in this Eternal City, Midalen can naturally see that the hammer of the holy weapon is in Joanke's hands, coupled with Joanke's own combat experience and strength, there should be no problem in solving a puppet undead one-on-one.

"Good!" Hearing Midalen's words, Joanke didn't say much, just nodded seriously, indicating that he knew.

Saying that, the two of them just picked up the weapons in their hands, and they had to make a move, regardless of whether the figure in the silver flame was very powerful or not, at least, it would never hurt to solve these four puppet undead first.

Even if the strength of the figure in the silver flame is very strong, everyone can concentrate their firepower on him without worrying about others disturbing him.

"Wait!" However, seeing that Qiao Anke and Midalen were about to rush forward, Lin Chen hurriedly opened his mouth and stopped Qiao Anke and Midalen.

Looking at the suspicious eyes of the two, Lin Chen's mouth explained seriously, especially to Qiao Anke, and said: "Wait a minute, no matter what, you have to push a puppet undead into the silver flame, I want to see how powerful the silver flame is."

"Yes! I understand! Although he didn't understand why Lin Chen had to emphasize that he was doing this, Joanke didn't hesitate anything, just nodded seriously.

Qiao Anke knew that since Lin Chen said this, then he must have his own deep meaning, and he didn't need to ask so much, he just needed to do what he said.

"Let's do it!" Hearing that Lin Chen had finished explaining the matter, Midalen said to Joanke, and as he spoke, two figures rushed towards the four puppet undead.
