The answer is twenty years and countless slaves' lives.
A wonder built with lives.
"…Can a monkey without magic build such a scene?", half lying on the table, Think leaned on her head and muttered to herself. Her eyes swept over all the models that had filled the entire floor of the room, and suddenly she smiled and said, "But according to the height described by Mr. Monkey, this pyramid and the Sphinx are much more magnificent than the Great Wall just now~"
Bang!
"How can they be the same!!!" Su'er slapped his hand on the table with his eyes wide open, and retorted loudly, "The Great Wall, the Great Wall, the key is that it is long! It has been built for two thousand years in all dynasties, with primitive technology and manpower to cross mountains and ridges in various dangerous places. Even in modern times, if you take photos from satellites, you can clearly see the Great Wall. What about the pyramid? It's just a small tomb!"
He was not drunk, but Su'er current state of drifting did look no different from being drunk, but his thinking was still clear and his courage had increased a lot - at least he dared to slap the table, which was an obvious improvement, although he didn't seem to see the dangerous look of Think opposite him.
"Satellite...", when talking about this, Okein suddenly sighed with emotion, "Humans can conquer the sky with wisdom and collective strength alone, and even step into the universe... In this way, aren't all our races petty?"
When calling Su'er and everything in the previous world, this divine species no longer used the name monkey.
"...It's a pity that humans on this planet can't repeat such a miracle." Su'er mood suddenly changed, and he sat back in his chair with a dull mood.
The reason is also very simple, these outrageous races that randomly jump back and forth on the edge of common sense and physical laws.
It's hard to imagine, right? Even in such an endless war, humans still established a country - yes, even now, humans on this planet have established their own country, but perhaps it is more accurate to call it a group of people who risk everything for Survival (original setting, please don't argue).
"But it sounds like the world before Mr. Monkey came here was not very peaceful?" Sitting on the chair and swinging his legs, Think glanced at the models called fighters, tanks, missiles, etc.
"This is indeed undeniable... Looking at the entire history of mankind, it is better to say that the so-called peace is just a short break between dense wars rather than saying that wars occasionally occur during long periods of peace." Su'er shook his head with a wry smile, "Everything has two sides. Although I don't want to admit it, I have to say that before I traveled through time, the two wars that affected the entire world were exactly the time when human technology developed the fastest in thousands of years."
"Ah, although I said this, it doesn't mean that peace will not promote technological development," Su'er quickly added, "It's better to say that many theories emerged in peacetime, even from computers and mobile phones, it's the same every year."
"Then what are you still worried about?" Okein asked calmly.
"Anxiety... internal friction?" Su'er gulped down another glass of wine unhappily. "It's obvious that if all humans united together and didn't target each other, they could probably colonize other planets before I crossed over. But in the last century, they could launch things to Mars, but in the new century, they haven't even left the solar system. If this continues, what will we do when all the non-renewable resources on the entire planet are exhausted... Pour the wine!!" Su'er raised his voice suddenly and waved his hands randomly, as if he could get rid of his worries. Without paying attention to Su'er somewhat out-of-control performance, Okein was unexpectedly good-tempered and refilled Su'er cup with spiritual oil. Tons, ton, ton, without stopping, Su'er picked up the cup and drank the newly filled spiritual oil. "...By the way, did I tell you about that?", Su'er turned his head and looked at Okein beside him in a daze, "...the international communist movement has failed..."
"Ah, I've said this twice," Okein followed Su'er and drank the cup, saying, "It is indeed a great idea, even I can't deny it."
"Really? That's great... What a pity...", Su'er had buried his head on the table, "If it can be realized, maybe all mankind can work together to use all the resources on the planet to build a spaceship to travel in the universe... Maybe we can come to this world... and take me home..."
Go home.
Su'er voice became smaller and smaller, with a barely perceptible sob.
"...Hahahahahahaha", a heroic laugh suddenly sounded. When Su'er looked up at the Old Deus beside him in confusion, the old figure dressed as a gentleman was laughing up to the sky, "Relying on a spaceship to travel between the stars? Talking across the world, it's really epic and magnificent! I like it!!" "If this day really comes, then I will invite them to drink a glass of spiritual oil", Okein patted Su'er shoulder hard and laughed, "Let's see what kind of heroes they will be." This is the promise made by the Old Deus. Su'er should not see the arrival of that day, both Okein and Think clearly understand this. "...Ah, thank you." Su'er wiped his wet eyes without understanding what such a promise meant. He was inexplicably touched. To be honest, Okein slapped him a little too hard, which really made him sober up. "Speaking of which, when did you find out about me and Nirvalen?"
"As soon as we entered the city," Okein replied, restraining his heroic laughter, but this answer made Su'er and Think look at each other in Surprise.
It was a very shocking answer, but for some reason, Su'er was Surprised to find that he was not Surprised at all and accepted it easily.
"You actually want to ask why I didn't do it or tell the children?" Taking off the glasses he was wearing, as if playing with a new toy, Okein gently blew white mist on the glasses according to the method Su'er told him before, and then gently wiped it with a square towel.
Without speaking, Su'er listened quietly.
"Don't make a mistake," Okein said with a wide grin. Only at this moment did Su'er feel the majesty that only belonged to the Gods from Him. "This is a test for the children. They are capable of handling it."
