"I see! Isn't the direction of the Sun Gate, the position where the sun shines through this door? Yellow light can be understood as sunlight. Shi Long suddenly realized.

"But...... There's one thing I'm not ...... yet," Xiao Xi hesitated.

"Don't worry about it for now, let's go and see!" Shi Long didn't care what Xiao Xi was thinking, so he pulled her over.

'Not true! Qin Hua thought in his heart, "This is too simple! How can a mechanism be so simple...... There must be a question, what exactly is this Puerta del Sol? Qin Hua looked at this stone door with polished inside, and was puzzled, "There must be something wrong with this groove!" Qin Hua looked at the groove at the top, but he really couldn't figure out what it was for, so he could only follow Shilong and them to the stone door facing the sun.

"Do you want to use the Kong Ming lantern to go down and explore the way?" Yan Yue said a little uneasy.

"It's useless, the passage below is sealed by a door, and if you want to enter, you can only open this door, but hitting the door means that the choice is confirmed, and if it's fake, it's bad." Xiao Xi said.

"Hmm!" Just as Xiao Xi was explaining, Qin Hua noticed that there was a light shining in his eyes, 'What's the matter?' I should have my back to the light! Qin Huachao light source approached and saw it. 'It's a mirror! Qin Hua saw that there was actually a mirror on top of this stone door!

'Why?' Why is there a mirror here? Qin Hua pondered. He looked in the mirror, and then in the direction the mirror was facing, and said, 'It's diagonal!' He found that the mirror was not facing the stone door, but ......

'Could it be ......' Qin Hua suddenly remembered something. 'Round grooves, balls, small holes, ......'

"Nozomi! What is the angle at which the sun is oblique here? ”

"Huh?" Xiao Xi thought for a moment, "20 degrees!" She replied.

"20°......" Qin Hua gestured on the ground, "Sure enough!" It dawned on him.

"What's wrong?" Looking at Qin Hua gesturing on the ground, Yan Yue wondered.

"If I'm not mistaken, the Gate of the Sun should be ......" Qin Hua ignored Yan Yue's question and muttered to himself, "Xiaoxi Key is in your hand, right?" ”

"Hmm!" Xiao Xi replied.

"Lend me one!" Qin Hua stretched out his hand.

"Huh?" Nozomi doesn't know what he's going to do with the key?

"Hurry up! If you don't find the door, the sun will leave just above you! Qin Hua said anxiously.

"......" Heath gave him the key after considering the pros and cons, after all, she couldn't be sure which was the real door, and her intuition told her that it was facing the sun and not the real door.

Qin Hua ran to the Sun Gate with the key, looked at the groove above the inside of the door, looked at the key, and pressed the key on the groove.

"Pound!" The key in Qin Hua's hand, that is, the black ball, was suddenly sucked into the groove.

"Sure enough!" Qin Hua was overjoyed, it seemed that this was a magnet principle, seeing that Qin Hua put the key on the top of the inner side of the Sun Gate, and it was sucked up, he was stunned, but Xiao Xi seemed to understand what Nan Nan said: "I see......"

"Then just ......" Qin Hua turned the key, pointed the small hole at the sun, and then pointed the other small hole at the mirror at the top of the stone door directly opposite, "This operation is a bit troublesome...... Qin Hua kept moving the beads trying to find the best position, and finally ......

"It worked!" In the eyes of everyone, a white light passed through the black beads, and shot onto the mirror on top of the stone door opposite, and then ...... A light that was completely yellow was reflected! The yellow light shines towards the stone door at an angle of 45°. The stone door began to sink after being illuminated by the yellow light

"I see! That's what the yellow light means to guide the right door! Yan Yue understood.

"Is it possible to use the dispersion of light to stay away...... This mirror only reflects yellow light...... "Xiao Xi said.

"......" is different from the previous two, Shilong is completely sluggish, and his IQ can no longer keep up......

"Looks like this is the right door." Qin Hua took the key.

"Yes!" Xiao Xi said affirmatively.

"Let's go! We're going to hurry! "Shilong took the lead and drilled into the hole.

At this time, seeing that the door was found, some people were happy and some were worried.

"Sure enough, there is someone who can open the door!" This is the one who rejoices.

"Damn! I was the first to get on the board! "This is a man of sorrow.
