The battle has left the ground, and these fire demons who can climb freely on the rock wall cannot fly, so they can only chase Lei Rui and Thor on the ground, rushing towards the side of the passage.

But behind the two of them, the flame giant Sutert saw that he couldn't catch up with the two, and the flame chain in his hand suddenly rolled back, accurately put on the head of the dragon-shaped monster flying from behind, and suddenly roared, his feet slammed, and the whole person was like a cannonball, soaring into the air, and landing steadily on the dragon-shaped monster's body.

Sure enough, he mounted his mount and pursued him closely.

The passage, the ground, the overhead, and the rock walls on both sides were crawling with dense fire demons, and the demons were towering, looking very terrifying.

Thor was a little numb in his scalp, and turned his head to look at Lei Rui, who stretched out his finger and pointed to the front Thor turned his head to look, just in front of the entrance of the passage, an orange-red ring suddenly appeared in the air.

This is the spatial portal that Lei Rui activated without moving.

Thor took the lead and went straight in.

Bang!

With a loud thud, Thor took Thor's hammer and fell to the ground. Just as he raised his head, he saw Lei Rui flying in. Then, the orange-red spatial portal still stood in the air, with no appearance of dissipation.

Thor sweated in his heart.

What if Sutert, the Flame Giant, rode his mount and followed him through the spatial portal?

He looked at Lei Rui, minus him in an arc in the air, suspended steadily in the air, staring at the orange-red spatial portal, that calm and relaxed look, waiting for the flame giant Sutert to drill in.

It's a trap! Thor suddenly understood.

Seeing this, Thor hoped that the flame giant Sutert would rush in. It's a pity that through the orange-red spatial portal, Thor can clearly see that the flame giant Sutert rode his dragon-shaped monster, tightened the flame chain in his hand, and stopped in front of the spatial portal, staying at that end.

Roar!

The flame giant Sutert and the dragon-like monster roared at the same time, and the sound shook the sky, low as rolling thunder, rolling through the spatial portal.

But they just kept this posture, and they just refused to cross the thunder pool by half a step!

The orange-red space portal in the air suddenly dissipated. Thor let out a long sigh of relief and said, "This damn flame giant is so cunning! And dug such a trap and waited for us to get into it. ”

It was dark all around, and here was the huge underground hall beneath the ground, and through the shaft-like passage in the middle, it was the kingdom of the flame giant Sutert.

Lei Rui landed and stood with Thor on the edge of the shaft passage more than 1,000 meters deep, looking down. A faint roar could be heard from underground, but it must have been the work of the Flame Giant Sutert and his group of fire demons.

"This is a very good opponent!" Lei Rui said, "Did your father tell you why he and Pol just sealed the Flame Giant Sutert back then, instead of killing him directly? ”

Keeping the flame giant Sutert will be a big hidden danger sooner or later. There must have been a reason why Odin and Pol gathered the power of the Asgard warriors to defeat the Flame Giants and seal the last Flame Giant Sutert underground.

Thor pondered for a moment, then replied, "He didn't tell me about it. Just told me that under the ground of Asgard, the flame giant Sutert is sealed, so that I can keep an eye on the movement underground. ”

"That's what he's always thought the flame giant Sutert wasn't enough to do." Lei Rui replied, "It seems that this guy, who has been quietly recovering and developing underground for so many years, has successfully escaped Asgard's attention. ”

"He's a big problem for me right now." Thor tilted his head, affirmatively.

That's really a problem for Thor now. It's just that when Lei Rui explained the situation clearly, Thor's face was very exciting, because he also immediately thought of this problem, in this place underground, fighting with the flame giant Sutert, no matter how he fought, he won!

But I couldn't lure him out. In such a situation, according to common sense, the flame giant Sutert would definitely chase after him, but as if he could sense the danger, he stopped in front of the orange-red spatial portal.

Looking down for a long moment, Thor let out a long sigh, retracted his head, and asked, "What now?" ”

Now, it seems that there is only one way to go deep into the ground and attack it. Otherwise, if the Flame Giant Sutert is allowed to continue to develop like this, his strength will only accumulate stronger and stronger, and it may even completely hollow out the entire Asgard interior!

At that time, Asgard was really going to be completely destroyed!

"It's troublesome!" Lei Rui muttered, "The Flame Giants originally emerged from underground, and now this Sutert is shrinking under the ground of Asgard, like a rat gnawing at the roots of a tree, if left alone, he will eat the roots of the tree sooner or later." Therefore, it must be managed, but it is necessary to see what kind of plan is adopted. ”

From the bottom of his heart, Lei Rui is not in favor of going deep into the ground to attack. Even if he could tangle up a team of powerful super soldiers, he still felt that it was still too dangerous to fight in that environment underground. If it causes the ground to collapse, then everyone will be served in a pot.

There are many super soldiers on Earth, and Lei Rui is not prepared to put them in a dangerous situation for the sake of this big trouble in Asgard.

Thor was silent, apparently thinking of a countermeasure. Lei Rui asked aloud, "Is there anything that has a strong attraction to this flame giant Sutert?" What was the eternal flame he was talking about? ”

"It's too risky!" Thor shook his head and replied, "The Eternal Flame, once it is taken by the Flame Giant Sutert, he will transform into a real Flame Giant!" At that time, it was really the twilight of the gods, the destruction of Asgard! ”

Lei Rui spread his hands and replied, "Going deep into the ground and fighting in the home field of the Flame Giant Sutert, this risk also exists, and his strength will continue to grow as he absorbs a large amount of flame energy released by the Flame Demon." The two options have their own advantages and dangers, but the latter can be controlled by us, of course, to control the risks. ”

This proposal made Thor's heart pound.
