Since coming to Beijing and no longer having to do farm work, the man's skin has become fairer.

In addition, there were occasional accidents where he would accidentally soak in his wife's hot spring water, causing his face to turn red and his skin tone to change noticeably.

To ease her husband's embarrassment, Wen Qinghe pulled her father over to show him Yan Xiao's latest creations.

"Dad, look at the puppy that Ayan made! It can even understand simple commands, it's practically a little robot!"

Then Wen Qinghe tossed a piece of candy a short distance away and placed the mechanical dog on the ground.

"Xiao Bao, go and pick it up."

The puppy wagged its tail and retrieved the candy.

"Dad, see, I wasn't wrong, was I? And it even has attack skills..."

Wen Qinghe excitedly demonstrated it to her father.

She first threw a crumpled piece of paper, which hit the office door.

"Xiao Bao, attack."

A miniature dart shot straight out of the mechanical dog's mouth and "whoosh" embedded itself in the wooden door of the office.

With perfect precision and penetrating insight, if this technique were applied to a battle between two opposing forces, locking onto the enemy's target before launching an attack would not only reduce casualties but also achieve a surprise attack...

Wen Yunhuai's pupils trembled slightly, his shock evident in his eyes.

Logically speaking, the first mechanical dog shouldn't have appeared until twenty years later; it shouldn't be here now.

But this kid has indeed quietly made one to amuse his daughter.

His eyes welled up with tears. This kid had created a miracle without saying a word.

He patted Yan Xiao on the shoulder, and his words were filled with excitement and pride that anyone could hear.

"Good...good! You're pretty good, kid!"

Like the Yangtze River, the new generation surpasses the old; there is hope for the rejuvenation of China.

This has shortened China's long road of scientific and technological progress by twenty years.

He had a premonition that the world would likely be different from now on...
