"When did this thing become like this?" Tang Li, who had been deserting before, never noticed what Xi Yue had done to Da Vinci when he handed the invitation to the self-portrait. Pen, fun, and www.biquge.info

"Do you see these two characters on this letter?" Xiyue said to Tang Li, pointing to the little boy and woman on the letterhead.

Tang Li's eyes widened again, carefully observing the letter in Xi Yue's hand, except for the newly emerging maps and red dots that could attract her attention, the little boy and woman looming in the corners of the letter did not get her attention at all.

The confused expression on Tang Li's face seemed to have become a norm on this island, and Xiyue, who was accustomed to all this, did not say anything to complain, but still explained to Tang Li very patiently: "When I first arrived on the island before, I told you that the 111 keys marked in the letter are actually 7. ”

"Oh, I know, it's supposed to be yin and yang and binary, right? Tang Li said with a slight hesitation.

Xi Yue glanced at Tang Li, although she looked obviously hesitant, she still nodded affirmatively, and continued: "It's true that the yin and yang arrangement and binary are true, but I actually had another basis for judgment at the beginning. ”

"Another basis for judgment?" Tang Li looked at the letter carefully, and finally noticed the little boy and woman on the edge of the letter, "Is this what you are talking about?"

In order to let Tang Li have a more intuitive understanding of this, Xiyue did not directly say the answer he guessed, but first talked to her about another topic: "Do you remember that Joshua once said that the so-called 7 keys on this island are actually for our 6 trials?"

Tang Li nodded a little ignorantly, indicating that she seemed to have heard of this topic, but Xi Yue didn't know how much she had listened to at the beginning.

"If I'm not mistaken, this trial should be of two levels of difficulty. Once the initial trial is completed, the evolutionary process that most scientists are pursuing on this island is basically complete, but if you want to ......"

"Wait, evolution, what evolution?" Tang Li was like a viewer who suddenly woke up from his sleep while watching a movie, asking his friends about the previous plot.

Seeing Tang Li's progress so backward, even if Xiyue was patient, she had to admit that it might take a long time to fully explain these things to Tang Li.

Xiyue looked up at the sky, let out a helpless sigh, and said to Tang Li: "Okay, after a while, it should be dark, it will be very unsafe and inefficient to conduct night operations on this island, today we will stay here for a while, take a break, take advantage of this rest time, I can explain to you well, what did we do after we arrived on the island?"

Regarding Xiyue's proposal at the moment, Tang Li naturally has no opinion.

"So, where do you start......

Just like Xi Yue said, the sky on the island gradually darkened after a while, and Xi Yue, who took out the reserve barbecue and settled the meal, began to patiently talk to Tang Li about Evolution Island.

After a long time of hard work and detailed explanations to make Tang Li understand something about evolution, Tang Li finally came to a thoughtful sentence, "Oh, I see, I seem to understand something." ”

Even if Tang Li finally understood the relevant explanation of evolution, Xiyue didn't get any sense of accomplishment in his heart, wasting a lot of time on this kind of thing, which was unbelievable for Xiyue in the past.

However, it seems good to think differently once in a while. Such a thought only stayed in Xi Yue's mind for a moment, and he was immediately driven away by the negative emotions generated by teaching Tang Li.

"Now that you understand the meaning of evolution, I will continue the previous topic, as I said before, this so-called natural selection competition, in fact, there are two kinds of difficulty, the first of which is the evolution we have now completed, after getting Joshua's approval, we who have obtained the two keys actually have the right to leave this island. ”

"But I don't want to leave the island yet. Tang Li looked at Xiyue very sincerely and said as a matter of course.

Looking at Tang Li, who didn't know whether it was naïve or innocent, Xi Yue showed an expression that she had known for a long time, and said to Tang Li: "I know you don't want to leave this island, so what we have to choose is actually the second difficulty, participate in the natural selection competition provided by the Science Society, get the remaining five keys, and get the chance to meet Darwin." ”

When she heard Darwin's name, Tang Li's big beautiful eyes clearly showed a hint of gloom, and the time spent with Xiyue always made her forget about her parents occasionally, but as long as she stayed on this island, this small island in the south would remind her of that cruel truth all the time.

"Can we find all the remaining five keys?" Tang Li asked with some concern, when he was getting the second key before, the good-looking man named Joshua had a big fight with Xiyue and had a hard fight there.

And listening to Xi Yue's meaning, Joshua, who inherited the wisdom of da Vinci, seems to have never done his best, but just this can suppress Xi Yue to a very dangerous point for a while, if those scientists are serious, will she and Xi Yue be able to overcome the difficulties they have encountered before?

The answer is unknown, because the world of scientists is also unknown to Tang Li.

"I don't know if it's going to work out, but I've got some clues now. As I said before, I judged that there were seven keys in this game, but there was another clue, and after getting Joshua's key, I was even more convinced of my previous judgment. ”

Speaking of this, Xi Yue paused, pointed to the little boy on the letterhead, and continued: "The number 7 occupies an important place in many myths and cultures, even from a purely mathematical point of view, the number 7 is also very special, in binary, 7 is also a special existence, the Greeks also believe that there are a total of seven elements that make up the whole world, father, mother, child and water, fire, and earth, which are the 7 keys we need to find." ”

"I still don't understand. Tang Li's question at this time was naturally expected by Xiyue.

Luckily, the night was still long...... (To be continued.) )
