Silver Lining

Zhao Yu came to the deserted planet to build a base, create an underground city and hide in it.
Worried about the threat from the unknown civilization, Zhao Yu dug out a small half of the planet and built star destroyer cannons capable of destroying the planet, as well as tens of thousands of fully intelligent mechanical dogs in various forms.
The defensive robotic dog, the Gate God, would disguise itself as a small mountain and fortify around the base.
Detection and gathering robot dog - Tsotan, would disguise as a rolling stone and wander around the planet to collect useful resources.
Combat robot dog - Nezha, would disguise as a crater, scattered around the base, ready to be able to attack the enemies that may come.
Around the base, they were ready to attack the enemies that might come.
On this day, his gathering robot dog - Tsotan, dragged back a spaceship. It captured three alien creatures, claiming to be from Earth.
Zhao Yu was confused. "Didn't I travel to the deep space of the universe? How come I'm on the back of the moon and being treated as an alien by humans?"

[Hint: The extreme rank Earth Level cultivation technique that you have fused and upgraded is extremely powerful, and the burden is huge. You can't use it before reaching the high-level of second tier. You might not explode and die at low level. That's still a risk on internal bleeding and damage]

Zhao Yu clearly had a higher-level marital art technique compare to the others, but as he could not use it yet.

As for the Extreme rank Mystery Level technique, it was between Mystery and Earth Level. It was invincible among first tier fighter, but it was not as useful as low rank Earth level cultivation techniques.

After all, the basic cultivation techniques of Ten Thousand Techniques Returning to the Origin were all yellow level techniques. Being able to upgrade them to the extreme rank of the mystery level was already the limit.
