"Oh, don't talk about this, we really know, I'll tell you about it." Qiu Ling'er said, picked up the water bottle and took another sip, looked at the crystals in the sky that emitted strong light, and said: "These crystals are actually just ordinary crystal ores, although they are very valuable, but from the perspective of ores, they are very ordinary and nothing special." ”

"Then why do they all glow, and the intensity of the light is not the same?" Bai Ling asked suspiciously.

"Because on top of these crystals, there are several bronze plates." Qiu Ling'er replied.

"What!?" Bai Ling and Zi Lingfei said in surprise in unison.

And Qiu Ling'er immediately explained to the two: "On top of these crystals, there is a large structural belt, and in this structural belt, there are all bronze plates at different angles, and these bronze plates are all special and can reflect the light source well, just like a mirror." Then on the ground, there are many hidden gaps, and the light from the sky shines on the gaps, and then through several bronze plates at different angles, they are constantly reflected, and finally reflected on the crystal ore, forming a situation where the crystal ore shines. ”

After listening to this, the two were shocked, and after a few seconds, Ziling Fei asked in a daze: "Then why is there such a big difference in the brightness of the crystals here between the ancient tomb and the ruins?" ”

"Look at your watch, what time is it?" Qiu Ling'er asked rhetorically.

Bai Ling and Zi Lingfei immediately looked at their watches and found that the current time was already 7:11 in the morning. At this moment, Bai Ling and Zi Lingfei suddenly realized the reason.

"With the change of moonset and sunrise, the brightness of the light will naturally be different, and the day is always brighter than the night, so the light that shines in during the day is naturally stronger than at night, so the light reflected into the crystal through the bronze plate is naturally brighter during the day." Qiu Ling'er said.

"In other words, the crystal lamps in the fake ancient tombs are actually already emitting this kind of strong light." Bai Ling said, his tone was firm.

"That's right." Qiu Ling'er said with a smile, and then made a supplement to Bai Ling, saying: "The changes of the sun and the moon, and then through the irradiation of the bronze plate and the crystal ore, even if it is underground, it can still simulate the changes of light sources such as day and night, what do you say." ”

The two were silent, they had been shaken.

"Amazing ....." In the end, Bai Ling said this sentence in a daze.

Bai Ling couldn't imagine the fake ancient tomb used to destroy the invaders, the special and strange insects in the fake ancient tomb, as well as this huge underground ancient city, and the crystals in the sky that would adjust their light according to the changes of the sun and the moon.

The people of Loulan have already thought everything through when designing this dungeon......

Bai Ling felt an incomparably shocked. Never underestimate the wisdom of the ancients, a sentence that cousin Bai Kaifeng often puts on his lips, but within a few days, Bai Ling has deeply felt it many times.

However, there is one thing that Bai Ling is a little difficult to understand.

This underground city was built during the period of Loulan's destruction of the country, and it belonged to Loulan, Bai Ling would not deny this, however, Loulan was about to be destroyed at that time, with their situation at the time, how could they build such a huge ancient city, and how could they have such a detailed plan.

Bai Ling thought of this question, but he didn't ask it, because he subconsciously felt that even if he asked, Qiu Ling'er and Qiu Shuang would not answer him.

Rather than being rejected by them and then alerted, it is better to investigate secretly by yourself and others.

Although Bai Ling trusts these two people, after all, they have known each other for less than half a day, so what should be conservative should be conservative.

"Go talk to Uncle Chen." Bai Ling said to Zi Lingfei, what he was referring to, naturally referring to what Qiu Ling'er said just now, he thought it was necessary to let Uncle Chen and them know. After Zi Lingfei nodded, he also turned around and walked to Uncle Chen's side to make a report.

At this time, Chen Nuo and the others also completed the connecting rope for the descent.

Ziling Fei walked over and reported to Chen Nuo, and Chen Nuo showed a surprised look in the process of listening, but after listening, he sighed and said to Ziling Fei: "I know, record all this, and then, think about completing the task first." ”

"Okay." Zilingfei nodded.

Then, Chen Nuo shouted to everyone: "Everyone, get ready to go!" ”

The distance between the cliff and the ground of the ancient city is very long, and it takes several bundles of rope to be used together to reach the ground. The ropes of the members present can be put together, and there can be two long ropes for the members to descend, and then a few more bundles can be brought out to be prepared.

After confirming that the rope was secure, Chen Nuo and He Qing fixed one end of the rope to the ground, and then the other end was directly falling off the cliff. Then, everyone was ready to start descending in order, holding on to the rope.

First, two people grabbed the rope and descended, and the others waited on the cliff.

After waiting for about three minutes, because the communication was restored, the people below sent a communication to the cliff, and the communicator on Chen Nuo's ear made a prompt tone, Chen Nuo immediately connected the communication and asked, "How is it?" ”

"Master Chen, everything is normal below, and nothing else has been found." Said the member below. When Chen Nuo heard this, he immediately put down his hand, turned his head to look at the other members, and shouted, "No problem below, brothers, go!" ”

After speaking, everyone began to grab the rope and descend in order, and it took about twenty minutes before everyone finally finished descending.

Bai Ling came down holding the rope from behind, and when he came down, he immediately looked around. I saw that in front of me was the block of the ancient city, and there were streets on the left and right, and there were ancient houses and buildings everywhere, but these buildings were covered with a layer of gray and looked very old.

"It's really well preserved." Beside Bai Ling, Lin Xian said.

"Hmm." Bai Ling nodded in agreement.

When everyone, including Qiu Shuang and Qiu Ling'er, came down, Chen Nuo immediately looked at everyone and said, "Everyone, immediately start the investigation of this ancient city, find the exit from here, remember, we are now few people, we can't disperse." ”

"Understood." Everyone said in unison.

"Get to work!" Chen Nuo shouted, then turned around and moved forward, and the others followed.

Everyone walked in this underground ancient city of Loulan and began to investigate the surrounding situation, such as the terrain and buildings, as well as the surrounding environment, etc., the records are relatively detailed, some take pictures, and some write with pen and paper.

The mission of the Tomb Breaking Alliance is basically for them to find the ancient tomb and then enter the ancient tomb to investigate. After learning about the terrain and cracking mechanisms, they will return to the tomb with the archaeologists of the Tomb Breaking Alliance and the National Archaeological Administration, take out the artifacts, and then conduct an archaeological investigation.

So, they're going to record it now so they can come back a second time.
