The content of the post is incredibly detailed. It not only clearly analyzes the various problems in psychic circuit design, but also provides practical solutions.

Xiang Fan's eyes lit up, and he almost flattened the screen with excitement: "Isn't this what I've been looking for?"

He was holding a rare treasure, taking notes quickly while muttering to himself, "So the delay between psychic nodes can be optimized this way... This is so clever!"

At this moment, the device started to malfunction again, making a harsh "squeaking" sound and the screen went black.

Xiang Fan patted his forehead and sighed: "Okay, you did your best."

He shook his head helplessly, copied the remaining content to local storage, and then reluctantly turned off the device.

The sunlight grew brighter, and a breeze blew in through the broken window, carrying a hint of earthy fragrance.

He turned his head and saw his father Xiang Su walking in from the door carrying a heavy bag of game collection on his back. His forehead was covered with sweat and his face looked a little tired.

"These are this month's income." Xiang Su took out a few spirit stones from the bag and gently pushed them in front of Xiang Fan.

There was a faint glow on the surface of the spirit stone, and its texture was so ordinary that it made people feel a little sad.

Xiang Su sighed and whispered, "The missions have been dangerous lately, and several people in the team have been injured, so the share is a little less. I'll try harder next time, and I'm sure I can get more back."

Xiang Fan held the spirit stones in his hand, remained silent for a moment, then raised his head and forced a smile: "That's enough, Dad. This is already very good. I don't need many spirit stones."

His eyes were drawn to the new scar on his father's arm, and a dull pain arose in his heart.

"Are you injured again this time?" he couldn't help but ask.

Xiang Su waved his hand, his expression relaxed: "It's just a minor injury, nothing serious. But you, don't be too frugal in your cultivation, use more spirit stones, don't be afraid of spending them."

As soon as he finished speaking, he turned around to sort out the prey, obviously not wanting to talk any more.

Xiang Fan watched his father's busy back, his nose aching. He whispered to himself, "One day, I'll make sure my father doesn't have to work so hard anymore."

The afternoon sun filled the courtyard. Xiang Fan took out a thick book on psychic theory and sat in the yard, reading it quietly.

The shabby mecha leaned against the corner of the wall, like an old soldier covered with scars. Although it was rusty, it still exuded a faint sense of tenacity.

"Whether it's cultivation or mecha, I don't really have big ambitions."

As Xiang Fan flipped through the book, he muttered to himself, "I just want to open a mecha repair shop and live a stable life with enough money to eat."

Xiang Su came over with a bowl of steaming rice soup. When he heard this, he was stunned.

He put down the bowl and patted Xiang Fan's shoulder gently: "This is also good. Peace and safety are the most important thing."

Xiang Fan took the spiritual rice soup and felt a warm sensation in his palm. He looked down at the few spiritual rice grains floating in the soup and nodded gently, "Yes, everything is fine."

After dinner, Xiang Su suddenly pulled out a small knife from his backpack and handed it to Xiang Fan: "I picked up a spirit beast claw a few days ago and sharpened it into a small knife for you. What do you think?"

Xiang Fan took the knife and looked at the rough iron-like thing. The corner of his mouth twitched slightly. "Is this... really a spirit beast claw? Why does it look like the broken iron piece of Uncle Hammer from the next village?"

Xiang Su laughed heartily: "Spiritual beast claws are just so simple! Don't be picky, as long as they are useful."

The father and son smiled at each other, and their original fatigue and stress were slightly dispelled by these few words.
