The Sidu Dragon King branch in "Black Myth Wukong" requires players to defeat four hidden BOSSs, and finally obtain a powerful weapon - the Flying Dragon Staff. The following is a guide to the Sidu Dragon King branch line in "Black Myth Wukong". I hope it will be useful to you.
Chapter 2-Flying Dragon Scales, Sidu Dragon King
Starting from the Earth Temple of "Shamen Village-Buji Valley", take the road on the left side of Shimen for the shortest route and see Sha Dalang. When fighting Sha Dalang, attract him to hit the wall with many small Buddha statues, which can open a crack (it doesn't matter if you miss it, you can also use the big-headed ghost spirit to open the crack afterwards). After defeating Sha Dalang, enter the crack and open the treasure chest to obtain [Flying Dragon Scales], which is a prop that triggers the hidden BOSS dragon in each level.
Teleport to "Huohun Cliff-Zhenshiping", turn right and go up the stairs to hear someone chanting sutras, interact to enter the Quicksand Waterfall, and fight the Little Li Dragon.
Defeat Xiaolilong to get [Dragon Ball], go up the stairs and open the treasure box to get [Treasure] Tridacna Pendant.
Teleport to the Black Wind Mountain "Green Wolf Forest - Outside the Forest" in the first episode, enter the waterfall and fight the red-bearded dragon.
Refer to the simple diagram I drew, starting from the Tutu Temple, the waterfall is on the far left, and you can find it by walking straight to the left.
Defeat the Red Bearded Dragon to get [Dragon Ball], open the treasure box to get [Treasure] Boshan Furnace.
Chapter 3-Sidu Dragon King
After defeating Lord Kang Jinxing and rescuing Zhu Bajie in "Sea of Bitterness-Turtle Island", go back and encounter the Earth Temple.
On the cliff near the Earth Temple, you can see a dragon fishing. This is the hidden dragon in this level. You need to obtain the Flying Dragon Scales from the previous level before you can fight him.
Defeat the Green-backed Dragon to get [Dragon Ball], open the treasure box to get [Soaking Material] Twelve-layer Glue.
Chapter 4-Sidu Dragon King
Pansi Cave - Juexiang Cliff, after defeating the right-hand insect, go forward and jump down from the left at the fork in the road to cross the bridge.
After crossing the bridge, there is a treasure chest on the right side of the cave. Go forward and encounter a small bridge.
It is easy to fall off this small bridge and start over again. It is recommended not to fight with the cocoon here. Stay away from the cliff, use Gathering and Dispersing Chi to become invisible, and then cross the bridge. (Be careful, if you are too close to the cliff, you will fall if you use the Concentrated Qi Stealth to make yourself invisible, so stand farther away)
After crossing the small bridge, come to the woods and get [Luojiaxiangvine] from the tree on the cliff on the right side of the road.
Continue walking forward, passing through a mass grave with a bunch of coffins, and come to the "Falling Dragon Wall" Earth Temple.
Continue walking past the Earth Temple and fight the last "Sidu Dragon King" Xiao Huanglong. It turns out that they are all the sons of the Jinghe Dragon King. The Gourd Immortal turned out to be Yuan Shoucheng.
On the left side of the picture below, there is a scorpion spirit.
Defeat the little yellow dragon and get [Dragon Ball] and [Treasure] Golden Carp. Pick up his weapon and get [Spell] Jin Lan, which can transform into a little yellow dragon.
