The old marquis was strong-willed throughout his entire life and was extremely strict in his own self-discipline. He was tough on himself, even tougher on his son.

He did not know what the word 'pamper' was. No matter if Gu Yun could see or not, or how he felt inside - his skills must continue to be honed, the iron puppets themselves wouldn't be lenient or hesitant because of Gu Yun's inconveniences either.

These puppets were not of the same kind that Chang Geng played with. Although the sword training puppet was terrifying, after being specially adjusted, it would stop at the right moment and would not hurt people when crossing moves.

When the actual iron puppets started to move, they became beasts made of metal - inhumane.

He had to rely on his weak sight and hearing, combined with the surrounding flow of air to deal with them. But no matter how hard the little Gu Yun worked, he would never be able to keep up with the requirements of the old marquis; each time as he started to adapt to a certain level of speed ​​and strength, the expectations were immediately pumped up to a higher notch.

The original words of the old marquis were: Either you will learn to stand up, or else find a place to hang yourself, Gu family would rather have no heir than raise a worthless child.

This sentence was like a cold steel nail, hammered into the bones of Gu Yun at a very young age. It could never be pulled out for the rest of his life. When Gu Yun entered the palace after the old marquis passed away, he still did not dare to relax for even a brief moment.

This kind of sense that had been honed for many years could always help him cover-up on a few occasions. This was also why he did not wear thick clothing if it was not cold to the point that his mortal flesh could not bear it.

Because thick fox fur and cotton coats would affect the sense of touch on his skin.

Gu Yun searched around for a moment in the air then wrote in Chang Geng's palm: "The one who just fought with you was a Dong Ying ninja. Those people excel at sneaking around. Beware of eavesdropping near the walls."

Chang Geng lowered his head; he couldn't help but grab Gu Yun's callused hand. Letting out a deep sigh that had been hanging in his chest, he shook his head with self-deprecation – Gu Yun would forever be calm and stable, and he would forever be frightened to death.

Gu Yun frowned. He did not know why Chang Geng was heaving such long sighs; he turned his head to 'look' at the boy, lifting his eyebrows.

As Gu Yun was blindfolded, Chang Geng looked at him to his heart's content.

Gu Yun's hand followed along his arm, moved to his head, and patted it.
