Zhang Yue has been busy these days, setting up a large stall. Although there are quite a few stalls in the Ancient God City, none of them are very large, because Martial Artists don't have many items to sell.
The most popular thing here now is to get equipment and medicine needed for the second level.
The purpose of medicine is to prepare for the passage through the extreme point, but most Martial Artists do not want to go to the third level, because the Mutated Beasts on the second level are already strong enough. It's not easy to survive there, going to the third level is almost like seeking death.
To survive on the second level, the most important thing is equipment, either cold-resistant or heat-resistant, just these two kinds.
