"But their attack was sudden. How could you have planned it all in advance?" Xiao Zhangliang asked, still puzzled.

"Prevention is better than cure. When you know what might happen in the future, you should prepare in advance."

Xiao Zhangliang nodded thoughtfully and said, "Thank you for your guidance, Brother Lu."

"I have another question: how did Brother Lu know so much information in advance?"

Scouts and assassins existed in this era, but they did not form a relatively large system.

Lu Li thought he would be the first, but it seems that the Mohist school has already formed a system.

Their intelligence network seems to be no weaker than Lu Li's Black Ice Platform.

"As a strategist, one must learn to plan ahead, act only after careful consideration, and make decisions only after thorough thought!"

These twelve words left Zhang Liang silent for a long time, as if he had been enlightened.

"As I said before, even if we use unconventional or risky tactics, we must do so within a controllable range."

It has to be said that Sun Tzu's Art of War is absolutely amazing. Sometimes Lu Li even wonders if this guy is a time traveler.

"The most important thing in war is intelligence. Only with more and more accurate intelligence can you make the right judgments."

Xiao Zhangliang was absolutely certain of this, because the shock Lu Li had given him today was immense.

In this situation, the Qin state was actually defeated by Lu Li's subtle maneuvering, which is something that not just anyone could do.

At least all the experts thought it was impossible, but Lu Li did it, and that was because he relied on intelligence.

"Brother Lu! Thank you!"

The two chatted for a while longer, and just as Xiao Zhangliang was about to leave, Guiguzi secretly arrived.

"Ahem, Zhang Liang, would you be willing to join my Ghost Valley and become my personal disciple?"
