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?"

[Level 2 Mission, Defend the Solar System, completed. Reward received, upgraded to the title of Mysterious Merchant.]

[Mysterious Merchant: Extra technology points can be obtained by trading with alien civilizations..]

"The reward for the mission is an upgrade of my previous title to title to Mysterious Merchant?"

Zhao Yu was kind of surprised with no options given after completing this task.

He double checked the benefit give by Mysterious Merchant title and realized it was similar as before.

Was the system playing some tricks on him was Zhaou Yu's first thought.

He opened the his diary and reviewed the previous records when he first obtained the Mysterious Merchant title.

Soon, he found an obvious difference.
