Shen Bing was not angry. He looked around, picked up a discarded bamboo stick, placed it on the table, and explained:

"Two to five hundred masters, please take a look."

"This is the Great Wall. It is about four hundred miles long, and every part needs to be fortified."

"That is to say, 30,000 of our troops need to line up for defense in these more than 400 miles."

"In this way, the average number of people per mile is only seventy-five."

"There are only seventy-five people per mile!"

"However, Zhao's 30,000 troops can be concentrated in one place to attack."

"Even if our army has the natural barrier of the Great Wall and can block ten with one, how can 75 people stop the 30,000 Zhao army?"

Hearing this, Zhang Xuan and Yang Ting couldn't help but froze on the spot.

Shen Bing shook his head:

"So what if we can support each other?"

"If the Zhao army attacks Cixian today, it will attack Anyang tomorrow!"

“Isn’t the Great Wall full of loopholes and dangers?”

Zhang Xuan was immediately speechless.

It is a deep-rooted thought of the ancients that defense is greater than offense.

In fact, we can't blame them, because at least on the surface it seems that defense is better than offense.

Until the German army broke this myth with a highly mobile dynamic attack.

People around the world were shocked to discover that it turns out that more often than not, offense outweighs defense.

Therefore, if Zhang Xuan gives up Shen Bing's "showing weakness to the enemy" and adopts passive defense.
