When you come to Cecilia's spaceship, you will see a red gem in the middle of the map. When you click on a gem, a Xuan Bing beast will fly around and take it away. At this time, you will see a machine in the upper right corner. Besides, his memory has disappeared. Click on it to know that he is Sita and accept the task of helping him find a souvenir of death.

Sail west tower introduction:

There is a premise to defeat the mushroom monster. Go to the lab first. There is a barrel-shaped fire-breathing thing over there. Adjust the proportion to 50% and you will get a flame cannon. Shoot the mushroom monster with it, the mushroom monster will be sprayed black, become quiet, and then start PK. The fire is 12, you can fight. It is best not to go to the water system, because it can kill a lot of blood at a time.

If you want to kill Kouga sharks, you need to get a diving suit first, and then go to the bottom of the sea to order sharks directly. He will take a shortcut, or the fish will blow him back to the last map (the round one with light on it). The fire department is 28, the water system is 25 (with some other strange things about 20 as meat shields), and the grass department is 20 if it is used well.
