I Let You Engage in Scientific Research, but I Didn't Drive You Crazy in the Kingdom of Light.

Traveling to the Kingdom of Light, he became Ultraman Stone, the younger brother of Ultra's mother, a scientific waste who likes to invent. Fortunately, the [Happy Inventor System] has been activated. As long as the invention makes the user "happy", he will be rewarded and become stronger! But there is a cheating setting in the system: all inventions come with a random "funny" side effect! When Captain Zoffi led the Space Guard, while dancing to "The Most Dazzling National Style", he pressed the monster army to the ground and rubbed it; When Ace releases the ultimate guillotine, he must shout out the second line of "Destroy you on behalf of the moon"; When his brother-in-law, the father of Ultra, watched the famous social scene of the Ultra brothers dancing together in a live broadcast across the universe... I, Stoney, have become the common nightmare of monsters and Ultraman across the universe! Monster: "I can't beat him, let alone fight him. It's such an insult to the beast!" Brother Ultra: "Stony, please, can the side effects this time be normal?!"
