The three old men nodded to each other, changing from surprise to flattering expressions, Jiang Yan looked at the sudden change of the three old men and knew what was going on.

"Young man, if you can really go to the core of the earth, and all the treasures of the three of us will be given to you, what do you think?" said Hua Pozi.

"Well, yes, but I want this stone gate, what do you think?" Jiang Yan replied

The crazy old man didn't think about it, and said directly: "Okay, if you fail, how about we take the stone gate and bury you?"

Listening to the crazy old man's words, the corners of Jiang Yan's eyes twitched slightly, and he thought, is this old man really crazy or fake crazy?

"Then lead the way, and I'll show you. Jiang Yan said indifferently.

"You're really not going to ask for my collection?" said Old Man Li vigilantly.

"Hehe, I really don't want your collection, although there are some treasures, but they are of little use to me. Jiang Yan said with a smile.

"Alright, let's go. Hua Pozi said.

When the four of them came to the ember furnace, the three old men all took a few steps back.

"Okay, you wait for me. Jiang Yan said, pushing the door with both hands, and a cloud of heat instantly covered the entire cave.

Just as the three old men were resisting the heat wave, there was a "bang" and the door was closed.

"Goodong" Old man Li swallowed his saliva with difficulty.

"Who the hell is this kid, and why is he so powerful?" asked Old Man Li with difficulty.

"Didn't Wan Jia'er say that he was his son-in-law. The crazy old man said.

"Well, let's wait, hopefully he'll make it to the core. Hua Pozi said.

In the ember furnace, Jiang Yan came to the heart of the furnace again, gently pushed a boulder at the bottom of the hearth, and the monstrous flames directly attacked, burning wantonly around him.

"Xiaoquan, do you have a map?" Jiang Yan said, standing on the upper layer of the mantle.

"According to the location of the host, it belongs to the depth of 255,000 meters below the continent, which is close to the submantle, and there is no underground map, only the underground detection distance and depth report. The system replied.

Looking at the flowing magma, Jiang Yan took off his body's clothes, "plopped", and jumped directly in.

The hot magma flowing around him was already 700°, and he continued to swim as if nothing happened.

At this time, he noticed that the color of the magma had turned orange, and the temperature was already close to about 1,000 degrees.

"Xiao Quan, how far is it?" Jiang Yan asked.

"Depending on your current speed, the host will need to pass through two layers of magma to reach the submantle. The system analyzed.

Jiang Yan gritted his teeth and moved desperately downstream, after passing through the golden magma, the last white magma in front of him, feeling the high temperature of more than 1200 degrees, he found that his skin also began to reflect, which was the reflection of Tongyuan.

He thought that after passing through the white magma, it would be even hotter, but he was surprised that it was covered with mystical stones, and it felt cold.

"Xiaoquan, report on the depth and distance. Jiang Yan said.

"The host you have reached the submantle at a depth of 1,200 kilometers and 1,200,000 meters above the ground. The system replied.

"Then how long will it take to reach the liquid layer?" Jiang Yan asked again.

"Depending on the current state of the host, it takes about 25 minutes to reach the liquid layer. The system explains.

Listening to the data report given by the system, Jiang Yan did not hesitate and moved quickly towards the cold area.

Just as Jiang Yan entered this cold dark area, a "whining" sound came into his ears.

The right eye turned quickly, looking in the direction of the strange sound, it didn't matter if he didn't look at it, he almost didn't scare Jiang Yan half to death.

Swarms of dense large "cockroaches" approached him, and the head of the cockroach turned out to be pointed.

"Xiao Quan, what kind of monster is this, how is it so similar to a cockroach?" Jiang Yan asked as he ran.

"Host, this is the Worm Mantis, they live under the lava and survive on the creatures of the earth. The system explained.

Jiang Yan didn't plan to make a move here, because he was afraid of causing a magma riot and something bad would happen, so he could only rush towards the liquid layer.

And what he didn't expect was still to come, not only the worm mantis, but more underground creatures began to chase after him.

A bulging insect covered in spikes was quickly approaching him, and just as the insect was about to bite Jiang Yan, a black giant insect of more than 50 meters instantly bit the spiked insect.

"I'll go! Is this the insect mobilization?" Jiang Yan shouted as he ran.

Just as he was about to approach the support level, a golden earthworm measuring 50 meters in size blocked his way.

"I'll go, is this an earthworm? It's so huge?" Jiang Yan complained.

Bursts of strange screams came closer and closer to him, and when he turned his head, goosebumps were all raised, and there were all kinds of strange reptiles. And the black giant insect that was more than 50 meters long was still biting the insect that was close to Jiang Yan just now in its mouth.

"Xiao Quan, is that a flea? so big?" Jiang Yan asked, looking at a bug with a wide belly and well-developed hind legs.

"The host is a flea-like creature, and it's the earliest form of a flea. The system explained.

"I'll go, it's not very peaceful underground, there are so many insects, I don't dare to do it, for fear of causing an earthquake." Jiang Yan said.

"The system advises the host to run towards the liquid layer, where it can be done without affecting the changes in the crust. The system analyzed.

Just as Jiang Yan was talking to the system, the golden earthworm behind him swept towards him.

With a "sting", the entire passage was filled in an instant, and Jiang Yan could only rely on Tai Youbu to dodge, and the dense insects also began to attack him.

"I'm sucking, this is going to swallow my rhythm alive. Jiang Yan dodged desperately.

Suddenly, he found that there was a half-human-sized space on the left side of the earthworm, and without thinking about it, he quickly crawled there.

And just as he climbed in, there was an earth-shaking fighting sound behind him, and groups of insects were desperately biting. When he first looked back, the tongue of a strange insect was coming towards him.

"I'll go, what the hell is this worm with such a long tongue?"

In the small space, Jiang Yan desperately dragged the long tongue to move, the sticky saliva also made him sick and half dead, if he let go, the long tongue would entangle himself.

"Host, what you're tugging at is a fly's mouth, not a tongue. The system explained.

"I'll go, you don't need to explain, right? I'm running for my life. Jiang Yan complained.

When he thought he was about to escape from here, the golden earthworm suddenly twisted, looking at the terrifying picture, Jiang Yan took out the burning stick, and with a thought, a long black knife appeared in his hand and slashed towards the earthworm's body.

I don't know if I don't know it, this stroke, the corrosive mucus begins to flow out. The insects smelled this and went even more frantic and attacked the golden earthworms.

"Xiao Quan, how deep is the distance?" Jiang Yan asked.

"Your current location is 2,900 kilometers from the ground, and 1,000 kilometers from the liquid layer. The system explained.

Listening to the fact that there are still 1,000 kilometers, Jiang Yan didn't hesitate, no matter what happened to him later, he ran there first and said.
