Every level of the Well of the Sun was a vast and boundless palace, and every building was so magnificent that humans seemed just like ants when they were in there. Most importantly, the materials that the palaces were made of were not affected much during the disaster of the collapse of the Tree of Eternity. Thus, they had to be very sturdy and durable.
Lin Li landed in the palace, and while he was flying close to the ground, he downed a healing potion that he had already prepared. Fortunately, the arrow that had struck him had already turned into mana and dissipated. The medicinal effects of the potion kicked in quickly and healed his wounds.
