Then, on the "Microorganisms" option, Zhang Tie saw the microorganisms he "brought" into the Black Iron Castle. They were some bacteria and yeasts on his body. Bacteria are more or less present in everyone. What is the role of this thing?

There are good and bad ones, so it’s not surprising. As for the yeast, I probably brought it on my body when I was making rice wine at home. I remember that I just ate three bowls of rice wine downstairs, so I guess I got some of it on my body unknowingly.

.Then these things followed him into the Black Iron Castle.

Click on the enlarged yeast that looks like water droplets, and a new picture appears.

On the left side of the yeast icon, there is a red cross, and below this icon, the system provides three pull buttons similar to progress bars. The three pull buttons correspond to the three basic attributes.

Attribute items - aura value, merit value, and basic energy.

Because it didn't seem complicated, Zhang Tie took a quick glance and roughly understood its meaning. The three pullable buttons seemed to represent the system resources he was willing to invest in this creature. As long as he was willing to invest,

resources, then the creatures or biological species selected by you will have a certain chance of evolving and mutating.

Zhang Tie then clicked on the red cross next to the yeast icon!

——Has the handsome and majestic Lord of the Castle decided to use the laws of space to obliterate the existence of this kind of creature? Reminder, once obliterated, it cannot be resurrected.

——Yes... Cancel...

Zhang Tie was startled by the cold words and quickly clicked Cancel, deciding to use this function as little as possible in the future.

It seemed quite interesting. After closing this window, Zhang Tie tried it again. The later function of "Special Seed and Fruit Generation of the Manjushahua Karma Ten Thousand Fruit Treasure Tree" was currently inactive.

This black iron castle seemed to be filled with countless secrets. Just when Zhang Tie was about to study it more carefully, a system prompt dialog box appeared in Zhang Tie's eyes.

——The system detects that the spirit and physical strength of the handsome and majestic Lord of the Castle are close to being exhausted, and all body functions are beginning to be in a negative state. Since the system's spiritual energy value is zero, it cannot provide a good recovery environment. The system recommends that the handsome and majestic Lord of the Castle is approaching exhaustion.

Leave the Black Iron Castle first, and then enter again after your body's energy is restored.

At the same time, the special "door" in the sea of ​​​​consciousness also sent out a slight fluctuation at this time, letting Zhang Tie know that if he wanted to go out, he only needed to lock the "door" with his consciousness in the midst of the noise, and at the same time say "go back" in his heart.

That’s it…

After such a reminder, Zhang Tie suddenly found that he was already very sleepy. After such a day of tossing, his emotions were ups and downs, and it was very exhausting. He yawned loudly, Zhang Tie thought for a while, and suppressed himself.

The urge to continue exploring here. I locked the door in my mind and said "go back" in my heart. Then, there was the feeling of walking through the tunnel in an instant. Even Zhang Tie's eyes widened and he didn't realize it was

How did he come out? He only felt the arch in his mind shake. He stood on the bed in his cabin. The scene around him suddenly changed. Everything that just happened was as if it had never happened before.

It's the same, where it came from, and where it came back. This feeling is like taking a family photo in a photo studio when the photographer pulled a certain string on the background wall behind him and then changed the background.

So fucking amazing!
