Guarding a reservoir? I am guarding the river of time!

The eldest and the third took Li Dong'er back to the Taishang Fairyland.

They let Li Dong'er live on the fairy island and arranged the best living conditions for her.

That day, the eldest and the third were discussing the plan for the battle of the domain a hundred years later.

"Brother, do we have to arrange a position for Dong'er?" The third asked the eldest.

"Of course."

After that, the eldest took out a token from his sleeve with the word "Shang" engraved on it.

"I plan to give this token to Dong'er."

After seeing that the eldest brother was going to give such an important thing to Dong'er, the third also waved his hand and said: "Brother, brother, this is not allowed!"

"Don't treat Dong'er specially because she is my sister, and give her such a valuable thing, no way!"

The third just asked the eldest brother's opinion to see if he could arrange a suitable position for Dong'er.

The eldest brother gave Dong'er the "Tiger Talisman" directly, which was equivalent to letting Dong'er directly serve as the Grand Marshal and the Supreme Commander!

Hearing this, the eldest brother glared at him: "What are you thinking? Do you really think I gave her the tiger talisman because Dong'er is your sister?"

"Instead, with her ability, she should be the Grand Marshal and the Supreme Commander."

"Dong'er is a wise god. If she doesn't serve as the commander, will you?"

"With Dong'er's wisdom and ability, she can control the overall situation as a commander, understand the entire battlefield in the future, and make the most perfect deployment."

After hearing the eldest brother's analysis, the third brother also nodded in sudden enlightenment.

Yes, Uncle Qingshan once praised Dong'er, saying that Dong'er is much smarter than him.

Once, when the third brother became the Heavenly Dao of a certain world, he went to see Uncle Qingshan once and played chess with him.

But even after becoming the Heavenly Dao, he never won a single chess game with Uncle Qingshan!

You know, during the years when he was the Heavenly Dao, his computing power, wisdom, and analytical ability were all invincible, but he never won once!

Later, the third brother found out why Uncle Qingshan wanted to play chess with him. It was because Uncle Qingshan had never won against Dong'er!

From this point, it can be seen that Dong'er's ability is far superior to Uncle Qingshan!

Therefore, it is indeed the most appropriate to let Dong'er serve as the supreme commander.

That day, the third brother came to a green-tiled fairy palace on the fairy island and saw Dong'er carving wood carvings seriously.

"Brother Daniu."

After feeling the breath of the third brother, Li Dong'er also put down the wood carving in his hand, stood up, and said with a smile.

Li Dong'er's voice was very nice, but her tone was very calm from beginning to end, just like a calm pond, never swept any ripples.

"Are you used to living here?" the third brother asked.

"Used to it."

Li Dong'er nodded.

"This is a gift from Brother Zhong."

The third brother took out the tiger talisman from his sleeve and handed it to Li Dong'er.

Li Dong'er took the tiger talisman with both hands, and then simply glanced at it, then looked up and said: "This is the tiger talisman, thank you Brother Zhong for your appreciation of me."

There was no need for the third brother to say a word. Li Dong'er only glanced at it and guessed the whole story. Her intelligence had reached a certain level.

At this time, the third brother waved his hand, and hundreds of thousands of scrolls appeared in front of him, piled up to five meters high and ten meters wide.

Then, the third brother pointed at these scrolls and explained: "On these scrolls are the leaders, arms, legions, generals, and the general situation of the distribution of forces of the major armies under our command. You should learn about them first."

As soon as the voice fell, Li Dong'er looked at the five-meter-high scroll, just a simple look for a few seconds, and didn't even open it.

"I've finished reading it." Li Dong'er raised her head and looked at the third brother, and said calmly.     Hearing this, the third brother, who was mentally prepared, was also shocked.

The information in these hundreds of thousands of scrolls is so huge that it seems pale and powerless to describe it as vast and vast, and the information in them is extremely complex.

To sort out these scrolls, the third brother specially found hundreds of great scholars and sorted them out for hundreds of years.

But. Dong'er just glanced at it and read it all? !

He knew Dong'er.

When Dong'er said he had read it all, he didn't just read it all, but remembered it all!

"Brother Daniu, please sort out the detailed information."

"It's best to be detailed to every soldier, their name, characteristics, strength, and advantages and disadvantages. The more detailed the better."

Li Dong'er thought of something and said to the third brother.

Hearing this, the third brother also took a deep breath and nodded, saying: "Okay, I have to wait for a while."

"What?"

"All read?"

After hearing this, the eldest brother was also shocked beyond words.

Hundreds of thousands of scrolls, even if one scroll is read per second, it will take hundreds of thousands of seconds, right?

The most important thing is that he didn't even open the scroll, but just glanced at it, and read all the massive and complex information, and remembered it all?

"Old Third, Old Third, you brought me an incredible person!"

After sighing, the eldest brother was also very surprised.

"Dong'er wants detailed information about each soldier?" The eldest brother continued to ask.

The third brother nodded, and he didn't quite understand this: "Yes, but the workload is too huge, isn't it?"

Let’s not look at other big worlds first. Just the ten middle-level fairy realms and fifty lower-level fairy realms under their command, the total number of cultivators is an astronomical number.

Because, in these fairy realms, almost all people are soldiers. The number of cultivators in one fairy realm alone is already an uncountable number.

The number of cultivators in a fairy realm is in trillions.

“Are you sure that every soldier and every cultivator is needed?”

The boss asked again.

There is a highest realm in commanding troops, that is, knowing the name of every soldier under your command, which is already incredible, and you can use troops like a god.

Dong’er not only needs to know the name, but also the characteristics, strength, and advantages and disadvantages.

Can you really remember so much?

Is your mind really not confused?

Even the boss himself, who has been commanding troops for so many years, can only remember the names of some major generals, because the information is too huge and too mentally exhausting.

"I'm sure that's what Dong'er told me."

"Brother, do you think we really need to collect this information?"

The third brother was also unsure about commanding the troops, so he asked.

Hearing this, the eldest brother stroked his chin and pondered.

After pondering for a long time, he finally made a major decision: "I've thought about it. Although this matter is difficult, we have to do it as much as possible."

"Notify Taishang Immortal Realm, ten middle-level immortal realms, fifty lower-level immortal realms, and all worlds participating in the future attack on the domain."

"Hand in the most detailed information of every soldier participating in the war, regardless of status or position."

As he spoke, the eldest brother paused and thought of a serious problem.
