Inside the grotto, it was dark and a bit eerie.
But everyone had good cultivation and could see in the dark without any hindrance, and they could see the murals around the cave at a glance.
The entire grotto is very large and deep, with murals everywhere, stretching for miles.
And those murals are full of characters, thousands of characters, all focused on fighting!
The places described in most of the murals are exactly battlefields!
Some battlefields are in plains, some battlefields are in valleys, some battlefields are on beaches, some battlefields are in swamps, and some battlefields are in rivers...
Most of the characters depicted in the murals are arranging troops and evolving formations during battle.
On the side of each mural, there are lines of small words annotating the content of the mural!
"Is this...the art of war?"
Lu Chen saw the clues of the mural and his eyes lit up.
Not far away, Yu Li was holding a stack of parchment paper and a pen, and was working hard to copy the murals.
"Boss, you're here!"
When Yu Li saw Lu Chen, he stopped writing and hurriedly greeted him.
"Yu Li, are these murals good things?"
Lu Chen asked.
"Yes, the murals here are actually a powerful art of war. In addition to marching and fighting, there are also many battle formations that can increase the overall combat effectiveness!"
Yu Li said, "These combat formations are very suitable for our legion. Once the legion learns these combat formations, the overall combat effectiveness will be greatly improved!"
"Is this art of war famous?"
Lu Chen asked again.
"Yes, it's called Six Paths of War!"
Yu Li replied.
"So how long have you been here and how much copy have you copied?"
"It's been ten hours, but I've only copied 1% of it."
"It's too slow. By the time you copy everything, the secret realm will have been closed long ago."
"Then there's nothing I can do. There are too many murals, too many characters, too many battle formations, too many colors, and it's very complicated. I can only copy them one by one, and I can't go any faster even if I want to."
Yu Li sighed and said, "I don't have enough time, so I can copy as much as I can. No matter what, it will be beneficial to the legion."
"This art of war is so powerful that it must be owned by my legion. I don't want part of it, I want all of it!"
Lu Chen said.
"I want to too, but I can't do it."
Yu Li said with a grimace.
"You don't need to copy, just write down all the murals. That would be much faster."
Lu Chen said.
"impossible!"
Yu Li shook his head decisively and said, "If it's memorizing words, I can do it. Even if I can't, there are many brothers with strong memories in the legion who can do it."
"However, these murals are too complicated, countless times more complicated than words!"
"It's not that difficult to memorize a mural completely. Even if someone can memorize it, it will take more time than copying."
"Moreover, this Art of War contains a lot of content. It takes up most of the cave and has thousands of murals. How can I remember it?"
"Wanting to memorize all the thousands of murals is more difficult than climbing to heaven. No one in the world can do it!"
Yu Li concluded so, Lu Chen's face also darkened,
Lu Chen's memory is considered very strong. After reading a book once, he can remember most of the content in the book. After reading it twice, he can remember everything.
But asking him to memorize these murals...
To be honest, if you read it carefully a hundred times, you can only remember 20%!
The murals are not only complex, but also very large. The smallest one is several feet high and one foot wide.
Not to mention the big one, the largest one is ten feet wide and one hundred feet high...
What's more, there are thousands of murals here, asking him to memorize them all?
That is simply abuse!
It's impossible to remember coming here.
He suddenly realized that his proposal was a joke.
Because he ignored one thing, that is, human memory has an upper limit!
To break through the upper limit of memory, one must reach a higher level.
Obviously, everyone has not reached that level.
"How about this, stop copying, learn the art of war in the murals now, and master it immediately."
Lu Chen could only say this.
In the entire legion, only Yu Li was interested in arranging troops, and only Yu Li had the talent in this area. Only Yu Li could do this job.
"Boss, I can't do it. All the murals add up to a military book, and each one is indispensable."
Yu Li shook his head again and said, "Moreover, this military book is so profound and difficult to understand that I have to study it slowly before I can remember it in my mind. This process is time-consuming, slower than copying, and it is unrealistic to study on the spot. I will wait until I finish studying it." , the secret realm has been closed long ago.”
"Then can you just learn some of these battle formations?"
Lu Chen asked.
"No, the book of war is coherent and must be learned from the beginning. You cannot learn part of it from the middle."
Yu Li said.
"Forget it, let's just follow what you said and copy as much as you can."
Seeing that neither this nor that would work, Lu Chen couldn't help but feel dejected and helpless.
"Young Master, Wan'er will help you write down the murals!"
Suddenly, Wan'er stood up voluntarily.
"There are thousands of murals, can you memorize them all?"
Lu Chen felt unbelievable.
"Wan'er can do it."
Wan'er nodded and explained, "The sacred tree technique that Wan'er has practiced not only enhances vitality, but also expands memory. Now the sacred tree technique that Wan'er has practiced has reached the seventh level. It has a strong memory and a large capacity. It can help Little Lord."
"Then try it. Remember as much as you can, don't force it."
Lu Chen said.
Afterwards, Wan'er secretly began to use the sacred wood technique, starting from the first mural, reading and memorizing it.
Wan'er took a few glances and finished the first picture, then it was the turn of the second and third pictures...
You only need to look at the small murals a few times, and you only need to look at the large murals a few times, very quickly.
An hour later, Wan'er had reached the end of the grotto and finished reading the last picture.
"Young Master, all the murals are in Wan'er's mind."
Wan'er jumped up to Lu Chen and pointed at her little head.
"So fast?"
Lu Chen was surprised, and the others also looked in disbelief.
"Wan'er is stupid, otherwise it could be faster and save at least half the time!"
Wan'er pouted and said this.
Can it be faster?
Wan'er's memory is really abnormal.
Therefore, everyone was shocked.
"How long will it take you to paint all the murals?"
Lu Chen calmed down and asked.
"About a month."
Wan'er thought for a while and said.
"too long!"
"Young Master, do you want to use these murals urgently?"
"Yes, I need some battle formations now to improve the overall combat power of the Fanatic Legion."
As soon as Lu Chen finished speaking, Yu Li quickly followed up and said: "Boss, even if you give me the entire Six Paths of War, I will still need a lot of time to study it before I can get it into my head."
