――――――――

As soon as Ling Feng jumped into the underground cave, he heard a loud bang behind him, and the hole that was several feet square was instantly closed. He was slightly surprised, but Ling Feng didn't care, his feet didn't stop, he followed behind Li Yuan step by step, and advanced towards the bottom of the cave.

The ground cave stretched downward at an angle of sixty or seventy degrees, and the four walls seemed to be chiseled by an artificial axe, very smooth, and from top to bottom, they were of average thickness, and Ling Feng had to bend down to keep moving forward in it.

Li Yuan, who was in front, also noticed that Ling Feng was constantly chasing after him, not caring if there would be danger in front of him, so he crawled forward along the cave passage.

Ling Feng bowed down and followed, persevering, chasing after him. If it weren't for the narrowness of the tunnel, Ling Feng would have caught up with Li Yuan a long time ago.

The two of them fled and chased, always maintaining a short distance, climbing downward.

One kilometer, two kilometers...... Five-kilometer, six-kilometer......

Ling Feng couldn't remember how far he had chased, this hole seemed to have no end and went diagonally towards the ground, and the surroundings were even darker, without a trace of light, Ling Feng could only roughly judge the distance between the two by relying on the faint yellow light emitted by the dragon sword and the bursts of sound made by Li Yuanqian.

Li Yuan in front of him was chased by Ling Feng behind him, and the future in front of him was unknown, and he was even more miserable and miserable.

Suddenly, a faint point of light came from the front, although it was extremely weak, but its appearance was like a fluorescence in the night, which made Li Yuan's eyes in the darkness suddenly brighten, and his heart was even more ecstatic, crawling forward even harder.

As he continued to move forward, the point of light gradually became larger and brighter, and Li Yuan's eyes couldn't help but flash a trace of excitement: "Ahead is the exit of the underground cave!"

Finally, Li Yuan, who arrived at the exit, did not hesitate at all, jumped out of the passage. Soon, Ling Feng, who was chasing after him, flashed and jumped out of the exit.

The scene in front of the eye made the two stunned.

Different from the narrow and dark passage, an extremely spacious cave was presented in front of the two of them. The walls that are more than ten zhang long and several zhang wide are inlaid with dozens of night pearls the size of a dragon's eye, illuminating the entire cave as if it were day. At the end of the cave, a white marble table carved with delicate patterns, neatly arranged three brocade boxes several inches long, the brocade box is golden and brilliant, very exquisite, at a glance it is extraordinary, it is conceivable that the items in the brocade box are extremely precious.

For a while, the eyes of Li Yuan and Ling Feng were attracted by the exquisite brocade box, one forgot to escape, and the other forgot to pursue.

"It's a treasure, after several hardships, I finally found this legendary treasure!" Li Yuan's face flushed with excitement, shouted, and rushed frantically towards the three brocade boxes at the end of the cave.

Glancing at Li Yuan, who was frantic beside him, Ling Feng frowned slightly, although he was curious about the items in the brocade box, he did not rush over rashly.

From the moment he entered, Ling Feng found that everything here was so mysterious and quiet, and there was a strange aura everywhere.

Because when things go wrong, there must be demons!

The experience of his previous life taught Ling Feng that no matter where he went or what he encountered, he should be careful in everything!

If there are treasures in those three brocade boxes, there will definitely be a mechanism to kill the person who took the treasure, if there is no mechanism, there will definitely be no treasure in the three brocade boxes, or the treasure has been taken away by someone, and the mechanism has also been triggered.

Sure enough, Li Yuanzheng, who ran to the stone table, happily opened a brocade box in the middle, and before he could take out the contents of the box, two iron locks suddenly stretched out from the ground, locking his feet, and at the same time, countless bright and sharp arrows on the walls on both sides directly shot him into a "hedgehog"!

"I... Finally found the legendary ... Dragon...!" Li Yuan's throat shook, and he trembled with his right hand to get the items in the brocade box, but his hand was halfway but hung down weakly, and his head was even more drooping in front of his chest, and he had no breath.

In the Lingwu Continent, there are treasure hunters every day, and because of the mechanism in their bodies, or fighting with others to grab treasures, there are countless people who die before the treasures.

When Ling Feng found the Heaven Turning Seal back then, if he hadn't been so cautious, he would have died in the Endless Sea, how could he have lived to this day.

Since Li Yuan was his own pathfinder, Ling Feng did not delay any longer, walked to the stone table, and looked down at the items in the brocade box in the middle.

I saw a hexagonal, one-inch-long shiny crystal transparent crystal nucleus glowing with a faint white glow in the brocade box, which looked very sacred.

"It's Long Jing!" Even though Ling Feng's heart was calm, he couldn't hold back the excitement in his heart at this moment.

Dragon Crystal is the essence and blood element condensed in the body of the divine dragon, and after tens of thousands of years of nurturing, the essence condensed into the essence element, which is second only to the "dragon core" on the divine dragon. It is rumored that it can help users improve their physique, nourish their bones, and regenerate their blood, and this treasure is priceless, even if it costs hundreds of thousands of silver, it is difficult to buy a piece. After all, the Divine Dragon is also a legendary divine beast, not only is the number scarce, but the strength is also very strong, which of the warriors who can kill the Divine Dragon and take out the dragon crystal is not a legendary existence, how can he care about hundreds of thousands of silver.

Ling Feng had only heard of the existence of "Dragon Crystal" from rumors, and had never seen it with his own eyes before, and now, he was fortunate enough to get such a treasure, how could he not be excited.

"Hey, it's really Long Jing! It seems that this Longwei Mountain is really an unlucky dragon who was killed by someone, but Long Jing was put in this brocade box by that person. "Chi" saw the dragon crystal in the brocade box at a glance, pursed his lips, and said to Ling Feng, "Your kid is really lucky, not only was he unscathed when he was framed by the eldest prince, but he also followed this fugitive to obtain such a treasure, it is really jealous!

Hearing this, Ling Feng's eyes lit up.

Cultivation requires training from a young age, slowly nourishing the physique, and laying a good foundation, so that in the future, you will have greater potential and great progress in the cultivation journey. And Ling Feng had never cultivated before he was reborn at the age of eighteen because of the blockage of his dantian, and he missed the best time to cultivate, and his own body had already been finalized, which had always been his biggest regret since his rebirth. Now, with this fast dragon crystal, he can help him improve his physique, nourish his bones and muscles, and make up for his regrets before the age of eighteen, which is undoubtedly great news for Ling Feng!

Thinking of this, Ling Feng couldn't help but swallow a large mouthful of saliva, carefully picked up the dragon crystal in the brocade box, and wanted to swallow it in one bite.
