Dinosaurs? How can dinosaurs exist in this place? Even on Earth, you can only find fossils of them, and they are lifeless. The brownish-black skin, short forelimbs, thick and powerful hind limbs, and large head and mouth all confirm that this is still a carnivorous tyrannosaurus. Lin Qian cautiously approached the valley, wanting to find out.

"Be careful!" An elf who hadn't gone far saw Lin Qian's dull gaze and shouted to stop him. The elf hurried over again and explained, "You can't enter this valley, and if you go in, you can't get out." ”

Lin Qian then remembered that Meryl had said that there was something similar to the Ancient Magic Array, and glanced at the female elf with some gratitude, who walked away with a slightly red face.

"It's quite charming," Isera laughed, "and the little girl is going to be gone and come back to remind you." ”

"Ahem, you'd better look at your kind. Lin Qian pointed to the tyrannosaurus and said.

"How is this the same kind...... They don't have wings, even wurms should have wings. And it has a bigger head, a thicker tail, thicker hind limbs than us, and no scales on its body, so it is by no means of the same kind. Ysera looked at it for a moment and came to a conclusion.

"But it looks a little bit like that. Lin Qian carefully recalled the size of the dragon, and it really looked like a dinosaur without its wings.

"You humans look like each other, and I don't see any similarities. "Ysera didn't want to be in the company of such wingless beasts, so she naturally looked for fault everywhere.

"Well, if it's not like it, it's not like it. ”

Lin Qian stared at it for a while, then picked up a stone and threw it towards the entrance of the valley, and finally the stone disappeared into the entrance.

"This magic array is much more clever than last time. Lin Qian muttered to himself.

"Lin Lang, you don't really plan to go in, do you?" Seeing Lin Qian's movements, Ysera asked with some concern.

"No, I don't want to die now, at least make sure it's completely safe inside. ”

Lin Qian thought for a moment, and then casually asked a magician for an inconspicuous magic staff, and lowered one end of the staff into the valley until only half of it was exposed, and the other half "broke" out of thin air and disappeared behind the invisible barrier.

"Long'er, do you guess this staff is broken?" Lin Qian stood still, turning his head to ask Ysera.

"It's broken, it should be directly dissolved. ”

"I guess it didn't break, but it went into another dimension. Lin Qian said and slowly took out the staff from it, and the part that had originally "disappeared" gradually "grew" back.

"What kind of magic is this?" said Ysera, who didn't believe her eyes.

Lin Qian smiled: "You can imagine this invisible barrier as a pool of water, but you can't see what is in the water, or you can only see an illusion in the water. ”

Lin Qian cautiously stretched out a finger and continued, "Anything that sticks in will disappear into your eyes, but it actually still exists, just in the invisible water. ”

"Lin Lang, your hand!" Exclaimed Ysera.

"Don't be afraid," Lin Qian smiled and reassured, "I'm feeling the air there, it's a little humid and hot, as if it's raining." ”

Retracting his fingers, he glanced at the raindrops on them, sniffed them, and licked them with his tongue again, which seemed to have no taste.

Ysera looked at him with good fingers, and with some curiosity, she put her whole hand inside, and also learned from Lin Qian to catch the rain there.

"How?"

"It's comfortable, it's getting heavier and heavier, and my whole hand is wet—oops!" Ysera suddenly exclaimed, and quickly withdrew her hand, clutching the hand she had reached in, crying out in pain.

"It's thunder!" Isera looked at Lin Qian's puzzled eyes, and squeezed out a few words from between her teeth while "sizzling" the cold air.

"It's a good thing you're a dragon, if I had just been hacked to death. Lin Qian was secretly glad while helping her rub her hands.

"Lin Lang, what kind of place is this, why is the weather completely different from outside?"

"I don't know, it's probably a paradise. Lin Qian looked at the giant beast and fell into thought.

"It's a pity that you can only enter from the outside, but you can't come out from the inside. Ysera remembered what the elf had said, and no one had ever been able to get out of it.

When Lin Qian heard her say this, he didn't believe it, picked up a small pebble, and chuckled: "What others say may not be credible, if you can come out, you will know if you try it." ”

"Wait for the rain to stop, don't be struck by lightning again. "Ysera is afraid of being electrocuted.

The two men sat down at the gate of the valley and ordered their men to keep watch around the valley, and from time to time Ysera put her hand in to check that the rain had stopped inside.

"Lin Lang, why are you so interested in this place?"

Lin Qian thought for a moment and asked rhetorically, "Do you remember the law of the beast riot?"

"Of course, I remember that once every four years, once in a hundred years, once in a hundred years, once in a hundred years, once a big one. "As a dragon, Ysera can certainly remember this.

"What about the specific date?" Lin Qian asked again.

"This one is different every time, it's going to be the last time-"

"—Is it right to add one day every four years?" Lin Qian interrupted with a smile.

"How do you know?" said Ysera.

"I also know that every hundred years you have to subtract one day, and every four hundred years you have to add another day, but you should not be aware of this. Lin Qian said again.

"Yes, we also found that it doesn't seem to be four years plus a full day, but less than a day, probably every hundred years does subtract one day. But these are the words of some of the wiser elders of the clan, and I have never told you before. How do you know?" Isela pulled Lin Qian to ask for clarification.

"It's very simple, because the calendar of your world is not accurate at all. Lin Qian smiled bitterly.

"Why is it not accurate?" Isera wondered.

"Because you don't have leap years, you have lost nearly half a day each year. And you've been about four years apart for the past six thousand years, and only this giant beast is sure to make a move at the same time every year. Lin Qian remembered the most basic things he had learned on Earth, but he wanted to show off here. (The actual time of the year is 365.2422 days, if there is no leap year, only 365 days...... Do the math yourself. ）

"I don't believe it unless you have proof of it. Ysera was visibly reluctant to believe it.

"Okay," Lin Qian thought for a moment and asked, "This is the 1500th rebellion of the beast, right?"

"Not bad. Ysera thought for a moment and replied.

"How many years have passed?" Lin Qian asked again.

"I don't know. "She's not a member of the clan who is in charge of timekeeping, so she doesn't know very well.

"Ask your people, you should know. ”

Isera looked for an old dragon with a suspicious face, asked it, and returned again with a puzzled face.

"6004, right? Exactly four years more. Lin Qian knew the result when he saw her expression.

"How do you know?" said Ysera, who at one point suspected him of eavesdropping.

"I didn't hear anything, I figured it out. Lin Qian said a little proudly.

"You're amazing," Ysera was finally convinced, "that's why you're interested in this place?"

"Not only that," Lin Qian suddenly sighed, and said with some emotion, "Actually, the calendar I am talking about is just the calendar of the world where I was originally located, and this giant beast is also a creature that has appeared there before, and I believe that their appearance here will never have nothing to do with me, or with my world." Even this world made me vaguely see the shadow of my original world. ”

Ysera was silent, she looked at Lin Qian with a confused face, and was inexplicably distressed. When he fell into this world that was strange to him alone, I am afraid that he would not be able to understand what kind of mood he felt.

"Well, it's time for the rain to stop, the thunderstorm won't last long. Lin Qian pondered for a while and took the lead in recovering.

Ysera carefully stretched out her hand again to experiment, and sure enough, she could not feel the rain, but on the contrary, she could feel the slightest rays of sunlight, and retracted her hand, and sure enough, there were no raindrops.

"Let me prove to you that space is actually reversible, and there is no place where you can enter but not get out. Lin Qian still took out the small stone, weighed it, and put the hand holding the stone inside.

"Look at it!" Lin Qian glanced at Ysera, snickered and stretched his entire little arm into it, then bent his elbow, shook his wrist, and a stone suddenly smashed out of thin air from the valley, hitting Isera's chest.

"Hey!" Ysera was directly hit before she could see clearly, and in a blink of an eye, she saw Lin Qian smiling at her, and then she realized that Lin Qian was deliberate. "Boring!" she said, picking up the stone on the ground, and also stretched it in, her wrist shook violently, and the stone flew towards Lin Qian's lower body. Lin Qian had already prepared, and hurriedly sacrificed his dark magic to block the flying secret weapon, so as to avoid the fate of being extinct.

Ysera didn't get a bargain and wanted to come again, Lin Qian hurriedly grabbed her, changed the subject, and said, "See, this barrier can obviously be passed through on both sides." ”

"But why did that elf say that there was no return?" Although Isera had drawn conclusions from Lin Qian's experiment, she still didn't dare to try it lightly.

"Just look at it. After Lin Qian finished speaking, he directly stretched out half of his head to take a look. Ysera hurriedly grabbed his body, for fear that he would be suddenly sucked in.

After the entire head was stretched out, Lin Qian slowly opened his eyes, and then with an "ah" sound, his feet were soft, and he was about to be planted inside. Luckily, Ysera was strong enough to pull him out like a chicken.

"What's wrong, what's wrong?" Isera was afraid for a while, in case Lin Qian couldn't get out......

"It's okay, I finally know why. Lin Qian gasped and said.

"Why?"

"Space is reversible, but gravity is one-way, and if you want to come back, you have to overcome gravity. ”

"What do you mean?" Isera didn't understand at all.

Lin Qian calmed down for a while, and then explained: "There is a bottomless cliff inside, and after entering, you can't fall down and come up." ”
