Mortal: I became invincible after becoming sworn brothers with Han Li.

The female demon smiled slightly, glanced at her daughter beside her, and said something meaningful.

"Don't worry, as long as you can retrieve my clan's treasure, I will not only let you go, but I will also give you a great benefit!"

"Senior, you flatter me. You saved my life, so I should do my best to help you. How could I dare to accept any more benefits from you?" Li Yunfan thought to himself, and directly refused with a cupped hand.

He wouldn't believe what the other party said. Usually, people who make promises of benefits like this don't end up well, and he didn't want to be one of them.

"Hopefully, she won't try to kill me, considering I just saved her daughter..."

Despite thinking this way, he was still prepared to fight desperately.

After all, this place was deep underground, surrounded by solid rock, so even if he wanted to escape, there was nowhere to go. Even if he escaped through the rock, given that his opponent's cultivation was a whole realm higher than his own, the chance of successfully escaping was almost zero.

Upon hearing Li Yunfan's words, the female Hanchi chuckled softly. Then, her snake tail slithered towards the cave entrance, as she spoke.

"Come with me!"

Li Yunfan took a light breath, turned around and followed.

The female demon led Li Yunfan through a long passage connecting to the large cave and into a stone hall several meters in size.

In the center of the stone hall, there is a three-foot-high cylindrical stone platform. At the top of the platform are carved three curved fingers, which sandwich a diamond-shaped red crystal that emits a faint glow.

"This is our clan's magical treasure, the 'Chixue Crystal.' To prevent the spiritual energy inside from dissipating, it is usually kept closed. It is only opened to enter when we need to get food or cultivate."

After the female demon finished speaking, she swam to the front of the stone pillar, reached out and touched a scale on her waist, and a red stone bottle appeared in her hand.

Seeing the other party take out the stone bottle, a look of surprise flashed in Li Yunfan's eyes. The other party did not have a storage bag on him, so where did he take out the stone bottle from?

If he were to unleash his divine sense, he would naturally be able to detect some clues. He could use his divine sense to probe a late-stage Core Formation cultivator. Unless he had a death wish, he would never do something so suicidal.

The female demon didn't care what Li Yunfan was thinking. She raised her hand, pulled out the bottle stopper, pointed at him, and a drop of red blood flew out of the bottle.

She then plugged the stone bottle with the cork again, and with a flick of her wrist, the stone bottle vanished instantly.

Then her expression turned serious, and she formed a strange gesture with her six fingers, speaking in the language of the Hanchi clan, which sounded like she was chanting some kind of incantation.

A moment later, the female demon stopped speaking and raised her hand to drop a drop of blood into the demon blood crystal.

The next moment, the blood crystal shone brightly with red light, covering the entire stone hall with a red curtain. Then, the red light slowly condensed and finally transformed into a hazy passage about six feet in size.

"The Blood Crystal has been opened, we can go in now." The female demon turned to Li Yunfan and said this, then slithered in first, her snake tail swaying as she went inside.

Standing next to Li Yunfan, the female demon known as "Bing'er" saw this and pulled him inside by grabbing his sleeve.

After passing through the red light passage, Li Yunfan's vision suddenly opened up, revealing a lush green landscape. He was currently in a valley surrounded by mountains.

He took a deep breath, and a breath of fresh, vibrant air, rich in energy and even carrying a hint of floral fragrance, entered his body, instantly invigorating him.

He spent half a year underground, and although he spent the whole time cultivating, the stuffy feeling of the space still made him very uncomfortable.

"Come with me, I'll take you to where the clan's treasures are kept!"

Upon hearing this, Li Yunfan immediately followed, while the female Han Chi Bing'er stayed close by his side.

The two, one man and two shivering creatures, crossed a narrow path through the valley and arrived at an unnamed gray forest.

These gray trees are straight and tall, with leaves that look like white five-pointed stars, hanging sparsely on the trunk, making them look like old trees that are about to die.

Li Yunfan had never seen this kind of tree before, and he looked at it with surprise.

"These trees are called 'Star Stone Trees'. Every fifty years, they produce a special-shaped 'Star Stone Fruit' that contains a trace of extremely pure water-attribute spiritual energy, which our clan uses for cultivation."

As if she could see the expression on his face, the female demon walking in front of him started to introduce him. After speaking, she took out a fruit from the scales on her waist and threw it to him.

Seeing this, Li Yunfan raised his hand and released a burst of spiritual energy to catch the Star Stone Fruit, summoning it into his hand. The fruit was about the size of his palm, oval-shaped, with a black hard shell on the outside and a blue line in the middle. It had a peculiar smell, neither fragrant nor foul.

"This...you need to open it...and eat the inside," said the female demon Bing'er, pointing to the fruit in Li Yunfan's hand.

Upon hearing this, Li Yunfan used both hands to peel off the outer shell, revealing the pale blue flesh inside.

Upon seeing the color inside, Li Yunfan frowned slightly; the shell didn't look very appetizing.

I took a sniff and found no other strange smell, so I boldly opened my mouth and took a bite.

The moment the fruit entered the mouth, the pure water essence contained within flowed down the throat into the body. And that essence was indeed extremely pure. As soon as it entered the body, it triggered the cultivation technique to start refining that essence.

Although he cultivates fire-attribute techniques, he can also refine other types of spiritual energy, just not as efficiently as fire-attribute spiritual energy.

A moment later, Li Yunfan's eyes lit up slightly. The purity of that water spiritual energy was so high that even he, a fire cultivator, had slightly increased his spiritual power.

Although the Star Stone Fruit doesn't look very appetizing, its flesh is indeed not very tasty. However, it has no strange smell, is quite juicy, and contains pure water essence.

So Li Yunfan treated it as a way to replenish his water intake, and finished it in four or five bites. He then put the remaining black shell into his storage bag, planning to study it when he had the chance in the future.

After passing through the Star Stone Tree Forest, a huge lake appeared before the three of them, with several large fish occasionally leaping out of the water.

"This lake is our tribe's food source. Every now and then, I bring my people here to fish, and then bring the fish back for our tribe to eat," the female Hanchi explained again as she swam along the lake.

Li Yunfan frowned slightly, not understanding why the other party was telling him all this. Why not just fly there directly?

Although he had some doubts, he figured he might as well listen since the other party was willing to explain. It would be good to broaden his horizons and think about how to save his life from the other party's clutches.
