The three major holy places, plus the two major dynasties, each sent an innate warrior to the front to explore the way.
The five people entered it and started searching.
About a quarter of an hour later, five people came out one after another, and one person said: "Your Majesty, we entered a secret passage. The secret passage continued to expand, and a hall appeared. In the center of the hall, there was a huge divine dragon.
He holds a round ball in his paws."
"There's no danger there!"
"Since there is no danger, let's go down!" Emperor Wu said.
With that said, he took the first step and entered the underground passage.
Warriors from other forces were not willing to lag behind and entered the underground passages one after another.
At the moment of entering, each other was wary and on guard, but they tried their best to avoid confrontation.
The fighting power of heavenly warriors and extraordinary warriors is too terrifying, and their destructive power is too powerful. They almost tear everything apart and destroy everything. The ruins have been opened several times because of the competition between heavenly beings and the powerful destructive power, which caused the ruins to be damaged and destroyed.
serious.
It was a pity afterwards.
Therefore, before opening the ruins, many forces swore with their Taoist hearts that in order to protect the ruins, they would not do anything lightly.
But there are exceptions to everything, and you can never be too careful.
The passage outside was relatively narrow, but you could follow the cracks in the ground. The further you walked underground, the wider you felt the ground became wider. After walking for five miles, a huge hall appeared, and everyone entered it.
This hall is huge, a hundred meters wide. In the center is a three-meter-high statue of a divine dragon. On the right claw of the divine dragon is a meter larger than a ball.
The ball is rolling up and down, and it seems to be extremely spiritual.
There is a complicated map on the sphere, with land, oceans, and countries on it, and the names of the countries are written on it.
Everyone came forward, observed carefully, and conducted archaeological research.
Soon, I saw a line of text at the base of the statue, "Use four colors to mark the different countries on the planet, so that the colors of the bordering countries are different!"
"This is the four-color law!"
Saint Xuefu said: "Among the civilizations born in the ancient ruins, there is a civilization called technological civilization. In this civilization, mathematics is the foundation, and complex technologies and complex weapons have evolved... Of course, most technologies have
We are useless, but we do have some interesting gadgets that can improve people’s livelihood!”
"In mathematics, there are many difficult problems, one of which is the four-color law, which is quite brain-burning!"
Saying that, Saint Xuefu explained some principles of the four-color law.
There are more than 200 countries on this sphere. Four colors are used to color these countries. The colors adjacent to each other are different.
"It's a bit head-scratching!"
Emperor Wu said and started to calculate.
Other warriors are also counted.
I started coloring the ball. It was inconspicuous at first glance, but it was still inconspicuous at a second glance. But after careful calculation, I was really in trouble. One hour, two hours, three hours, four hours... One day passed, and there was still no answer.
, still can’t color it perfectly.

"Congratulations to the fourth prince, he is expected to ascend the throne in the future!"
In the Imperial Capital, as the big bosses left one by one, the world became quiet.
Suddenly, Li Mu had the feeling that there was no general in Shu, so Liao Hua was the vanguard.
"I'm just lucky, I happen to be the fourth child!" The fourth prince was much more modest, "I'm just a supervisor of the country, not a prince. Even if I am a prince, I may be deposed!"
My father has a great desire for power and has great control over power. Faced with such a father, it is actually difficult to be a prince.
If you do too well, the emperor will be constantly jealous, and will wonder if the prince is trying to seize power, and if he is trying to evade the emperor; if you hide your clumsiness, hide yourself, and do things mediocre, the emperor will also wonder if the prince is incompetent or not.
It's not time to replace the prince.
Neither is excellence, nor is mediocrity. It is difficult to grasp the balance between them.
Nowadays, the supervising country has great power, but the fourth prince does not have much confidence that he can reach the position of crown prince or even emperor.
"Now that the emperor has decided, he will not change it easily. The court cannot withstand the twists and turns!" Li Mu said, "Stability is everything now."
"I hope so!" the fourth prince said, but lacked confidence, "Go to the mansion and have a few drinks!"
"good!"
Li Mu nodded.
When we arrived at the mansion, we drank wine with each other, changing glasses, and our friendship deepened.
The emperor has left, and many heavenly beings have left, making the originally unstable world even more unstable. All these heavy burdens need to be shouldered by them.
While drinking, suddenly the news came from the summons.
The fourth prince listened to the news and said with a smile: "At the gate of the ancient ruins, they encountered a sculpture. The sculpture was a dragon holding a ball. There were more than 200 countries on the ball, using four colors, adjacent to each other.
The colors of the countries should be different!”
"The question is simple! At first glance, it seems really simple, but if you think about it carefully, it's not simple at all!"
"Those heavenly beings and extraordinary warriors have been calculating for more than a day, but they still don't have a clear answer!"
Li Mu said: "This is a four-color problem!"
The fourth prince said: "It is said in the ancient ruins that these are three major mathematical problems. They seem simple but are difficult to prove!"
"Actually, the hardest thing to prove is that one plus one equals two!"
Li Mu smiled.
"Wait a moment!"
The fourth prince arrived in the courtyard and waved his hand. The soil was immediately absorbed and fell on the palm of his hand. The true energy was compressed and squeezed, gradually forming a ball. There were clear country divisions on the ball, and there were
The name of the country is very similar to the size of the ball in the ruins.
"This is the iron ball in the ruins!"
Li Mu looked at the iron fairway: "Actually, it's not hard for them. They have outstanding computing power. They can get the answer in ten days at most!"
In the past life, the four-color law could not be solved by the human brain. In the end, it relied on computers to brute force crack, permutation and combination one by one, and constantly eliminate from tens of billions of permutations and combinations, and finally found the correct answer.
In previous lives, relying on the human brain really could not solve this problem.
But in this world, when you reach the Grand Master, you condense the Yuan Shen. The Yuan Shen has huge computing power. In the early stage of the Grand Master, Li Mu’s computing power is 100,000 times per second. When the Grand Master completes it, his calculation power is 300,000 times per second, which is half a step.
Humans do it one million times per second, and in the realm of gods and humans, it does it ten million times per second.
As for the perfection of heaven and man, the extraordinary state, the calculation ability is even better.
Yuan Shen is equivalent to a computer and has terrifying computing power.
It is estimated that the four-color law will not be difficult for those strong people, and it will definitely be cracked in ten days at most.
Li Mu looked at the sphere casually, and suddenly felt familiar. The topographic map of the country and the terrain of the continent seemed extremely familiar, and his knowledge of geography from his previous life emerged.
