Netherworld Mountains and Seas: Ancient Ruins Dragon Coffin

Chen Yanqiu's ancestral book, the Broken Book of Mountains and Sea Ruins, records that there is an underground ancient ruins left by the ancient Shennong clan deep in the Qinling Mountains. The mountains are foggy all year round and difficult for strangers to enter. The three of them teamed up to go into the mountains, encountering primitive mountain forest miasma, lost illusions, strange beasts in the mountains, and cliff plank road mechanisms. They first explored the surrounding ancient tombs and discovered the murals and sarcophagi left by the ancient ancestors. They revealed the first secret: there are not only human dynasties in the world, but also ancient hermit clans guarding the underground dragon veins.
