Chapter 486

"What the hell are these?"

Su Li couldn't help but flip through these messy books, wanting to criticize them properly.

It was simply dirtying people's eyes.

Then, Su Li criticized every page of every book properly.

One of the books particularly caught Su Li's attention.

The cover of this book was tattered and did not have any name.

It looked plain and unremarkable.

But the content inside was exceptionally stylish.

"The formation of the two instruments, producing armor and troops, disrupting the ranks of the soldiers, is called change; there are also formations of the four symbols and eight trigrams, which are called escape..."

This book was somewhat obscure and difficult to understand, 5.9 vaguely containing the way of marching and deploying troops, but unfortunately, it was very thin, and it looked like a remnant copy.

So Su Li quickly scanned through it.

However, at this moment.

A system prompt rang out.

"Ding! You have read the rare military book "Six Secret Teachings - Martial Teachings," comprehended the military book characteristic "Martial Teachings," and your command value +10!"
