When Dongfang Xin was worried, Mei'er took out a packet of powdered medicine from her arms, she handed it to Dongfang Xin and said, "This is sulfur powder, the nemesis of the snake-shaped demonic beast!"

Dongfang Xin was overjoyed when he heard this, he took the sulfur powder and poured all the powder into his hands, staring at the movement of the black-bellied snake.

"Sneer......"

The black-bellied snake spit out the letter and let out a hiss, and rushed towards Dongfang Xin and Mei'er with a fierce look, Dongfang Xin calmly looked at the black-bellied snake that was getting closer and closer, and the sulfur powder in her hand was also clenched tighter and tighter, Mei'er was afraid out of nature, she felt her heart jump out and hurriedly shouted, "Scatter sulfur scatter!"

Dongfang Xin was not in a hurry and remained silent, but the source qi in his body had been running rapidly along the tendons, seeing that the black-bellied snake was getting closer and closer to the two, Mei'er was so frightened that she covered her eyes, just when the black-bellied snake was 2 meters away from the two, Dongfang Xin made a move, his clenched palm opened violently, and the fierce energy multiplied with the blessing of the source qi, and the strength mixed with sulfur was like a sharp sword hitting the body of the black-bellied snake.

Suddenly, more than a dozen black-bellied snakes exploded into a pile of powder, Dongfang Xin's arm swung out again, and a strong wind swept away the ashes of the black-bellied snake.

Mei'er looked at everything that was happening in front of her, she couldn't help but say, "I didn't expect you to be so powerful!", Dongfang Xin smiled faintly, and he took Mei'er to the cave again.

Walking in the quiet and dark cave, a chill lingered around, only the footsteps of the two could be heard in the quiet cave, the dark and cold environment, she looked up at Dongfang Xin who was walking slowly, in this environment, Mei'er felt that the closer she was to the teenager, the more secure she had.

In this environment, the two walked for about half an hour, and just when Mei'er couldn't stand the cold, Dongfang Xin suddenly stopped.

"Oops......" When Mei'er's body couldn't stop, it hit Dongfang Xin's back, and the softness on Mei'er's chest was suddenly flattened under the impact force.

"Intimate contact" made Mei'er's pretty face crimson, and she said angrily, "Stop and don't say hello."

The "intimate contact" just now made Dongfang Xin cough dryly, he pointed to a stone gate in front of him that emitted a faint fluorescence, and said helplessly, "There is no way!"

Hearing this, Mei'er Dai's eyebrows frowned slightly, she took two steps forward, looked at the stone gate in front of her and said, "What's behind the stone gate?, since someone is digging a cave here, I think there must be a mechanism!"

Dongfang Xin also came over, knocked on the stone door with his hand, made a "bang" sound, shook his head, and said helplessly: "The stone door is very thick!"

"You can't break down the door with brute force, and if you force it, it will collapse the cave. If you look at the fluorescence on the stone door, it is likely that someone has set up a trick here, as long as you are careful, you will definitely be able to open it!" Mei'er said softly as she touched the stone door.

"Do you know the trick?" Dongfang Xin asked curiously, Mei'er said with a faint smile, "I heard grandpa say something before, I have read books on this subject, I dare not say that I am proficient, but it is generally no problem to crack it." Mei'er said casually, but the movements of her hands did not stop, and she kept groping for something with her hands.

Just when Dongfang Xin was helpless and ready to give up, "Found it!" Mei'er shouted ecstatically, Dongfang Xin set his eyes on the stone gate again, next to the stone gate, Mei'er's slender hand touched a bulge on the stone door, her fingers pressed down, and there was a creaking sound.

Seeing the stone gate slowly moving upward, Dongfang Xin exhaled a breath like a heavy responsibility, he gave Mei'er a thumbs up, and as the stone gate moved up, a burst of light expelled the darkness in the cave cleanly.

Dongfang Xin smiled slightly, and then walked in with Mei'er, when the two stepped into the stone door, the sight in front of them widened, inside the stone door was a huge stone room, the fluorescent stone used for the former to shine on the wall of the stone room, there was a table and a chair in the center of the stone room, a skeleton sat on the chair, seeing the scene in front of them, the inner room was more weird.

On the table, there is a bluestone platform, and there are 3 locked jade boxes on the bluestone platform, and the jade boxes are neatly placed there, and there are a lot of gold coins and ores piled up in the corner of the stone room, and such a large number of gold coins are probably not less than hundreds of thousands.

Dongfang Xin was overjoyed, the ore and gold coins were exactly what he lacked, Dongfang Xin looked away from the gold coins with difficulty, and his eyes stayed in the last corner.

There are all kinds of medicinal herbs stacked in the most corner, how important these precious medicinal materials are to Mei'er.
