Outside the Shattered Ice Valley, there is a snow forest planted with snow crystal bamboo. Often, buckets of snow crystal bamboo liquid are brought into the city by hand-made carts with wheels.

This wooden bucket is similar, except that the wheels are fixed directly to the bucket.

"Hehe, Haiyao asked me to come and help try it out. This wooden barrel is so much fun, but it's too tall. My tentacles can't quite reach the ground, so it's really inconvenient to move around."

Beya jumped back into the wooden tub, and the clothes she hadn't had time to change out of instantly got soaked, now looking exactly the same as before.

The tentacles extending from the wooden barrel were barely touching the ground, struggling to move the barrel slowly forward.

"...Stop it, don't wear the tentacles out."

Su Yuan sighed and rubbed his forehead in exasperation. Only Bei Ya could push herself along like this; with a barrel this tall, the mermaids would have to stick at least half their bodies out of the barrel.

Haiyao pushed another wooden bucket over, looking at Su Yuan with expectant eyes.

"Su Yuan, is there any way to let everyone go to Moon Pivot City to play? They haven't become awakened warriors, nor are they witches, so they can't transform their tails into legs."

These days, she has tried many methods, but either she needs help from others or she can only stay in the city for a short time before having to return to the water.

There is a river outside Moon Pivot City, but it flows into the city's underground pipes, and the water channels above are only the size of a palm.

So Haiyao, who usually likes to play around, went to the library to study for a while and finally figured out this wheel bucket that is useful but not particularly useful.

"There is a solution... let me think about it."

The solution Su Yuan could think of immediately was a wheelchair. He could attach large wheels to both sides of the wooden bucket, and then simply push the wheelchair forward.

Turning is also easy; you only need to turn one side to do it.

As for other solutions, he couldn't think of any for the time being.

At most, he could only add some magical patterns to his improved wheel hub, such as to keep it stable or to prevent water from leaking out.

"Alright, let's leave it at that for now. If all else fails, we can try to build a city on the seabed once Hailing arrives at the Dream Coral Sea."

After thinking it over, Su Yuan carried Bei Ya out. The wooden tub was too tall, making it particularly difficult for her to move around.

First, you need to lower the height a bit, and then put a layer of soft cloth around the wooden barrel, otherwise it will be very uncomfortable to lie on the wooden board all the time.

Finally, and most importantly, is the wheel. The wheel that allows the vehicle to move itself is made of two wheels: the inner wheel rotates, while the outer rim is responsible for pushing.

There are currently no rubber items in Moon Pivot City, but there are many items that are made of the same material as rubber.

The vine currently in use is called White Lotus Vine, which was found in the forests of the Wangxue Mountains. The sap from its roots is mixed with sandstone crystal powder.

After steaming, soaking, and drying, a tough, durable solid gel is formed, which is very effective in shock absorption and wear resistance.

Su Yuan found a busy little beast girl and asked her to go to the white rubber shop in Starsea Town to buy some of this white rubber.

This stuff is not only widely used in Moon Pivot City, but also in this Star Sea Town, where some ships need it for sealing, filling, anti-collision, and shock absorption.

Therefore, some animal girls have opened white glue shops in Starry Sea Town.
