Yaochen did not let Xiao Yan walk alone this time, but directly took him through the desert.

It only took half a day for the two to reach their destination.

It's a flat sandy area, and there's really nothing special about it above the desert.

Compared to this place, Xiao Yan even felt that the swamp full of stench and black water was more like a hiding place for strange fires.

It's just that the markings on the map make him understand that there must be something unusual here, just like the swamp, the monster that is comparable to a fighter is obviously not the most powerful creature.

Xiao Yan looked around, and after not finding anything too magical, he put his eyes on his feet.

"Teacher, if there is a fire here, then it should be underground, right?" Xiao Yan said.

Yaochen nodded lightly: "The strange fire is indeed underground. ”

Xiao Yan's face was happy: "Then let's go down?" ”

"How do you go down?" Yaochen looked at Xiao Yan with a smile.

Xiao Yan's little face became bitter, and he said, "You must have a way, you can't let me dig down, right?" ”

Yaochen smiled and shook his head.

Immediately, he said with a straight face: "I originally wanted to take advantage of this trip to the desert to hone your strength, but I don't have that much time to ......."

He took a deep breath and said, "This time, I will assist you in refining the Qinglian Earth Heart Fire, but after I leave, you must not slack off!" ”

Xiao Yan had reluctance and expectation on his face.

Facing the teacher's solemn look, his expression also became solemn: "I will definitely not relax." ”

The master and apprentice sat on the sand.

The scorching sun shone above the dome, making the ground scorching with grit.

Xiao Yan didn't feel uncomfortable at all, he listened carefully to Yaochen's words.

What Yaochen talks about is the method of absorbing foreign fire.

Normally, three things are needed to absorb the alien fire: the Blood Lotus Pill, the Ice Spirit Cold Spring, and the Na Ling.

However, with a Douzun-level powerhouse taking care of them, these three items seem dispensable.

Even so, absorbing alien fire is an extremely dangerous thing, and if you are not careful, you will be burned into nothingness, even if there is a strong protector!

Yaochen's tone was slow and he spoke extremely seriously, Xiao Yan listened carefully, not daring to be careless.

He knew the danger, and he was determined to get it!

It took more than three hours for Yaochen to tell the story in detail.

After confirming that Xiao Yan understood, he got up and asked Xiao Yan to get out of the way.

After getting up, Yao Chen's surrounding momentum changed suddenly, causing a trace of fear to flash in the eyes of the Amethyst Winged Lion King who was lying in the distance.

A white flame appeared in Yaochen's palm, and his right hand covered it, and the flame left his palm and fell to the ground.

When the flame touched the sand on the ground, it melted like boiling water falling into the snow.

The flames fell diagonally downward, and a diagonal passage appeared above the desert.

About two minutes later, Yaochen slowly exhaled and set his eyes on Xiao Yan.

Xiao Yan paused slightly, and then walked towards this passage.

Yaochen followed behind his students.

Before leaving, he couldn't help but look into the distance, and the corners of his mouth hooked up a smile.

Xiao Yan held the moonstone in his hand and walked in the dark passage.

It wasn't long before he reached the end of the passage, and his front opened up with a lake of magma.

The rolling magma made the underground extremely hot, and in the midst of the magma, Xiao Yan felt a terrifying energy fluctuation at the same time.

As he felt the scorching breath and tried to see the traces of strange fire above the churning lake, he suddenly heard and noticed something different on the surface of the lake.

It seemed as if something was swimming towards him beneath the magma.

Just when Xiao Yan had just come up with this idea, there was a sudden "bang" sound from the magma, and a huge red shadow rushed towards him.

Panic filled Xiao Yan's entire heart, so much so that his breathing became disordered.

At this time, he became surprisingly calm again, and almost without hesitation, he rolled on the spot, and fell from the mouth of the passage to a low platform beside the lava lake.

The huge figure suddenly froze in the air.

Xiao Yan turned around and saw the medicine dust with an indifferent face.

"Teacher." He said with palpitations.

Yaochen nodded, looking at the two-headed fire spirit snake in front of him.

This two-headed fire spirit snake is about four or five zhang long, and its whole body is fiery red, like a beautiful jade carved from the earth fire.

It's just that its four diamond-shaped snake pupils are full of bloodthirsty killing intent.

"This kind of mutated demonic beast is rare, and I think it was also affected by the strange fire, so it became so ignorant of life and death." Yaochen said indifferently.

He originally thought that if he revealed the cold fire aura of the bone spirit, he should scare away the demonic beasts that might exist underground, but this guy was not afraid at all.

Yaochen was about to kill it, but saw Xiao Yan and said, "Teacher, you can spare its life." ”

Yaochen frowned, looked at his disciple, and said strangely, "When did you become so kind?" ”

"I just think," Xiao Yan smiled and said, "Such a living demonic beast should be worth more than death." ”

Only then did Yaochen react.

He chuckled and shook his head, saying, "I'll leave it to you." ”

With a flick of his fingers, a cloud of white flames flew out, causing the two-headed fire spirit snake to fall into the magma lake.

"Only a strange fire can break the seal of a different fire," Yao Chen said, "so you can only succeed, otherwise it won't have much to do with you." ”

Xiao Yan nodded.

The atmosphere became eerily silent.

After a while, Xiao Yan couldn't help it, pointed to the magma lake, and said, "Teacher, the strange fire is down here?" ”

As he spoke, he kept wiping the sweat from his forehead, and his heart was a little depressed.

If it weren't for his recent surge in strength, I'm afraid he wouldn't have been able to stay in this hot place at all.

Even so, he knew he couldn't stay long.

While Xiao Yan threw out his questions, Yaochen nodded and said, "That's right." ”

"Then you ......" Xiao Yan wanted to speak and stopped.

"You can go down." Yaochen said.

His tone was flat, as if he were saying, "You're going to eat."

Xiao Yan's eyes widened, and at this moment he had the urge to "deceive the teacher and destroy the ancestors".

"I ...... Lack of strength. Xiao Yan bowed his head and said.

"And what do you ask?" Yaochen looked at him.

Xiao Yan: "......"

"What are you waiting for?" A few minutes later, Xiao Yan asked again.

"Wait for someone." Yaochen said.

Xiao Yan blinked, and then realized that the teacher was not deliberately teasing himself.

It's just that he wonders who needs Yaochen to wait.

"Could it be that the other party is very powerful?" Xiao Yan thought to himself.

Suddenly, a name popped into his mind, making him slightly abrupt, but then there was even more intense confusion.

"Even if it's her, it doesn't seem like the teacher needs to wait." Xiao Yan frowned.

The corners of Yaochen's mouth hooked up a smile, and said, "She's here." ”
