Episode 15 recap: Hu Ba Yi's life was hanging by a thread.

Fatty asked Da Li to do some work, and Da Li reluctantly took the rope and arrived at the work site. Unexpectedly, he saw a merman emerge from the water. Startled, he quickly hid behind a giant rock. After the merman came ashore, he circled around the rock. Da Li skillfully maneuvered around and managed to avoid being noticed by the merman. When the merman returned to the sea, Da Li remained hidden nearby, observing. Fatty approached and suddenly patted Da Li's shoulder, startling him almost to the point of jumping up.

Fatty had encountered the merman before, so when Da Li finished recounting the encounter, Fatty grabbed a submachine gun and nervously kept his eyes on the water's surface. Just as he was about to pull the trigger, he unexpectedly noticed that Hu Ba Yi and the others had returned. As soon as Hu Ba Yi resurfaced, a massive explosion came from the sea floor. After Hu Ba Yi entered a password, the Divine Land Disk started to activate. He suspected that the rocket was about to launch, so he quickly informed everyone to get to the big wooden stake.

Upon hearing Hu Ba Yi's words, everyone gathered their personal belongings and hurriedly ran towards the big wooden stake. At that moment, hundreds of merpeople suddenly jumped out from the sea floor and launched an attack on them. The merpeople fought against Hu Ba Yi and the others on land but were clearly at a disadvantage. Fatty sprayed the submachine gun, mowing down the merpeople in front. However, their numbers were numerous, and they kept coming in waves. Hu Ba Yi and the others ran out of bullets, while the merpeople showed no signs of diminishing. On the contrary, their numbers continued to increase.

The group fought while retreating. Da Li was the first to climb the spiral ladder on the big wooden stake. In the midst of the battle with the merpeople, he accidentally broke the ladder. When Fatty saw that Da Li had cut off their retreat, he cursed loudly. Da Li ignored Fatty and, without the merpeople chasing them anymore, he lay on the ground, closing his eyes to rest. Suddenly, he felt a wave of heat on his face. When he opened his eyes, he saw a large merperson leaning over him.

During the fight with the big merperson, Da Li and the merperson fell down together. Hu Ba Yi, Fatty, and the others fought while retreating toward the center of the big wooden stake. When Da Li fell, there were several more explosions from below, and smoke and flames immediately engulfed him. Ming Shu, Fatty, and the others were the first to climb to the top of the big wooden stake. The thought of Da Li being gone saddened Ming Shu.

Hu Ba Yi and Sherry Yang held their ground. When they saw the big wooden stake shaking violently, the others quickly threw down a rope for them. After Sherry Yang climbed up, Hu Ba Yi was about to climb up when suddenly, Da Li emerged from the sea of fire and desperately grabbed Hu Ba Yi's leg, begging for him to save him.

Hu Ba Yi pulled Da Li up and was about to climb up while carrying him when the iron chain of the big wooden stake suddenly broke. The two of them fell together.
