If he don’t want to his grandchild to suffer, he won’t be able to reap the benefits either

When Old Master Xi said this, not to mention Xi Rui, his eyes were wide open in disbelief.

Even Xi Xinheng was stunned. "Father, are you joking?"

His son was pampered and spoiled. 

If he went to the northern border, he would probably cry and want to come back within three days.

Old Master Xi nodded with a serious expression. "Of course I'm not joking.

"Rui'er is already a grown-up. It's not bad for him to train at the northern border.

"Let's arrange for him to follow Xiao Hanzheng."

Others saw the northern border as a den filled with tigers and wolves, but Old Master Xi felt that this was an opportunity.

When was the best time to make a contribution? 

Of course, it would be when the situation was chaotic.

When there was peace and prosperity, how could there be so many opportunities to contribute?

Although Xi Rui, his grandson, was a profligate, he was not incurable.
