After walking for about half an hour, I was already close to the entrance of the tunnel. The entrance to the cave is so hidden that you can't tell that it's a stone door unless you look closely.

Yiyun's eyes narrowed slightly, staring at the stone door, on which was a combination lock.

"Oh my God, why is this lock so hot!" Kagawa's slender fingers just covered the lock, and the temperature on the surface of the iron lock was so hot that he retracted it like an electric shock, and shook it in the air a few times.

Yiyun also felt the temperature around him slowly rise, and the surrounding earthen walls turned dark red and appeared white.

"Get out of here!" Yiyun yelled as he realized that something might have happened outside, and the surface of the earthen wall became hot.

Kagawa smiled and nodded solemnly, his fingers moving quickly on the combination lock keypad.

The iron combination lock made a crisp sound, and Kagawa pulled the handle on the door despite the hot temperature, but the stone door did not move.

"Damn! The door is broken. Kagawa yelled angrily, putting his finger to his mouth and holding it.

"Pry open!" Yoshiyun said in a commanding tone, staring at Kagawa as he looked rather calm.

Kagawa was taken aback by Yoshiun's cold tone, and saw Yoshiun with his arms clasped in front of his chest, looking at him with interest, looking like he was watching a good show.

"I wanted to see what I was capable of. Kagawa reappeared with that bright and innocent smile on his face, and pressed his fingers on the wallet around his waist.

The brown leather wallet, opened and there were several silver wires inside, Kagawa skillfully pulled out one of the alloy wires, he approached the iron lock of the stone door, focused on the side of his head, and his fingers twitched briskly against the keyhole.

"That's it!" Kagawa snapped his fingers, retracted the alloy thread and pinned it back to the wallet around his waist, and kicked the door open.

"Boom!" The mine outside had already turned into a sea of fire, and the temperature in the air was terrifyingly high, and in just an instant, the skin was burned red.

As far as the eye can see, the mine is red, and the crystal ore flashes with red light, as if it has been burned hot charcoal, as if it will explode and crack in the next second.

"Damn, what's going on?" Yiyun hurriedly covered his mouth and nose with the corner of his clothes. Fan a few wisps of sparks fluttering in front of him.

At this time, there was no one in sight in the cave, Yiyun glanced at several escape routes in the cave, and the last pair of eagle eyes locked on a place with a small fire and walked away.

"Don't go over there!" Kagawa covered his mouth and nose, grabbed Yoshiun, and said vaguely.

Yoshiun frowned and looked at Kagawa dissatisfied, thinking that he had been pulled towards a place where the fire was fierce.

"What does this guy want to do. Despite his doubts, Yoshiyun followed Kagawa towards the sea of fire, and for some reason he had an inexplicable trust in the young man in front of him.

Bright yellow flames jumped between the stones, and two figures ran quickly in the sea of fire. Flames burned in the corners of the clothes. Soon a large hole was burned, and the skin was scorched by the scorching firelight, and Yiyun clenched his teeth, and the corner of the clothes in his mouth had already been burned into a rag.

But you can't let go, and once you inhale the billowing smoke, you will definitely die.

Soon the two of them broke through the sea of fire and came to an open land, Kagawa hurriedly found a water pump, and he and Yoshiun extinguished the fire on his body.

"Nearly burned me. How the hell is this on fire!" Kagawa said scolding, his mouth dry. Smoke in his throat and a few mouthfuls of water he swallowed.

Yiyun stared at him, as if he had something to ask.

Kagawa handed over the water pipe, and his delicate face was black at this time, like a little flower cat. He pointed to the sea of fire and said, "I know the terrain best here, and there is no road behind the road you just chose. And there are some flammable products in the back, and you will die if you choose that way. ”

As he spoke, he suddenly thought of something, poured himself up and down with a water hose, drenched the strip of cloth on his hand and covered his mouth and said, "Get out of here quickly." ”

The two of them continued to walk towards the north of the mine. The fire here is smaller than just now, and if you look into the distance, you can see the light jumping in, so you must be not far from the exit.

Thinking of this, their pace quickened a little.

"Boom!" Suddenly there was a loud noise ahead, and then the road ahead broke open a large hole, and the mud and earth tiles on it fell straight into the abyss, and no response was heard.

Yiyun hurriedly paused to keep himself from falling, and he took a few steps back to avoid collapsing again. Drag Kagawa, whose center of gravity is unstable and shaky, to a safe place.

"It must have been the collapse caused by the loosening of this rock due to the high temperature!" Kagawa said with an earthy face, his mouth still whispering, this was exactly what he was worried about, he didn't expect it to happen, if he hadn't left here a long time ago, he would have been buried alive in this damn mine!

"What to do! What to do!" Kagawa said anxiously as he paced, his mouth shattered.

It is impossible to rush through the three-meter-deep abyss in front, and there is no way to retreat from the sea of fire spreading behind.

Smoke poured out more and more from behind him, and Kagawa's eyes were filled with fear, and his forehead was covered with a fine layer of sweat.

"Why? Are you so afraid of death?" Yoshiyun saw the panic in Kagawa's heart, and the corners of his mouth rose in disdain, revealing a mocking smile.

"Just... Not at all. Kagawa's face was flushed, and he shook his eyes at Yoshiyun, and said in a stumbling voice, looking a little lacking in confidence.

Thinking that he has been lurking in the underworld for more than ten years, every time he is in danger, he has not lost his life, and today he finally found a clue but he wants to be buried in this inexplicable sea of fire, thinking of this Kagawa is full of unwillingness.

"Follow me!" Yoshiyun pulled Kagawa up the walls of the mine.

"What are you going to do!" Kagawa's face was puzzled, seeing that the corners of Yiyun's mouth were still smiling, he was a little suspicious in his heart that he was really the spear god Yiyun?

Following Yoshiun's gaze, Kagawa saw a stone road above the mine to transport ore, so it was! Kagawa's eyes flashed with a bright light, and there was an iron car parked on the stone road, enough for two people.

The two of them quickly climbed the narrow stone road, and Yoshimo and Kagawa got into the car and pulled down the brakes. The car started slowly, the iron wheels rubbed against the track and made a dazzling sound, and the speed of the car slowly increased, rolling to the other side of the stone road.

When the car passed the stone path above the abyss, Kagawa secretly glanced down, and if this Nima fell, he would not be crushed. He closed his eyes at the thought of this, as long as the car passed through here, he could leave this damn place!(To be continued......)
