It didn't take long to go in, and when I returned again, I had already changed the passage I entered, and everyone's feeling was completely uneventful.

What the hell is going on?

Li Bingtian squatted on the ground, his eyes staring at the gates, and he was silent for a long time, as if he was thinking seriously.

The members of the scientific expedition team were also silent and did not disturb him, Wu Qing and Tuoba Yanqiong sat cross-legged, seized the time to recover, Zheng Ya took out his compass, also squatted on the ground, kept judging the direction, and turned on the geophysical prospecting instrument.

Yi He squatted beside Zheng Ya curiously, watching Zheng Ya operate the compass very naturally.

The compass in Zheng Ya's hand, the full name of which is "multi-functional natural electric field geophysical prospector", is a kind of field source stability, high precision and high efficiency that integrates some of the essences of magnetotelluric sounding, MT, AMT, frequency sounding and transient electromagnetic method...... A magical device that can detect all kinds of special magnetic fields, discover special minerals, and find water sources.

Before today, in the process of Zheng Yake's expedition to the tomb, the compass was only used to determine the direction.

But today, Li Bingtian taught Zheng Ya a vivid lesson, many times, some scientific knowledge can be flexibly used in the ancient tomb, according to Li Bingtian, Mentor Xiaofei is enough to be a master with his name, so that is to say, these pieces of equipment passed on to him by Mentor Xiaofei may be real treasures.

These things, if you use them well, may be able to change everyone's situation.

After half a ring, Li Bingtian sighed leisurely, and said in his mouth: "The setting of this ancient tomb is quite high-end, in the corridor, there are auxiliary road mechanisms, from any door to enter, it is possible to enter different auxiliary roads, such a setting, it really makes people feel the wisdom of the ancients, it is really vast." ”

Zheng Ya squatted on the ground and said, "Professor, come and take a look, I seem to have made some discoveries." ”

Li Bingtian perked up, and said in his mouth: "By the way, Xiao Fei's technology and ability of me and I are very complementary, usually, as long as the two of us cooperate, there is no place in the world that we can't go, Zheng Ya, you have obtained Xiao Fei's true biography, maybe we can really find a way to crack the mechanism if we work together." ”

With a bright smile on his face, Li Bingtian came to Zheng Ya's side and looked at Zheng Ya's compass with both eyes.

Zheng Yashou gestured a few times on the compass, and said: "Professor, you see, there are some metal frames in the passages and gates in front, and their composition is completely different from the soil layer. ”

Li Bingtian looked at the diagram drawn by Zheng Ya on the compass, and said: "Yes, with the skeleton display of your geophysical detector, I finally understand that the corridor in front of me seems to be immovable, but in reality, it should be a mechanism similar to a chain flap. ”

found the problem, Li Bingtian immediately found a solution, patted Zheng Ya on the shoulder, Li Bingtian said in his mouth: "Xiaoya, it's good, let's go, go in again......"

This time, Li Bingtian made some requirements for the distance between everyone and the rules of walking: "Everyone must remember my previous entrance tips, only in this way can we walk into the normal road and not go back to the old road again......"

Everyone walked cautiously, and it has been relatively smooth, but it didn't take long for the ancient zombie to block the road in front of everyone again, that is to say, everyone is now on a road that everyone has not walked in the previous two times.

Seeing this result, Li Bingtian was stunned for a moment, and said in his mouth: "How is it possible? This time it should definitely not be wrong, why does it seem to be wrong again?"

Zheng Ya looked at the geophysical prospector in his hand, and said in his mouth: "Maybe it's really a mistake, I don't know what the reason is, our position is a little biased again, professor, should we go back and come back?"

Li Bingtian nodded heavily: "Naturally, we can only come again, otherwise, when we finish the corridor, we will still walk back obediently." ”

The group began to return, and it didn't take long for them to reappear in the hall again, and suddenly found that this time, the door where everyone appeared had changed again, that is, everyone had gone wrong for unknown reasons just now.

After coming out, compared with Zheng Ya's geophysical prospecting instrument, Li Bingtian carefully studied the method of passing the test, and confirmed that his judgment was not wrong.

Feeling that there was no mistake, Li Bingtian led everyone to go in again.

However, it didn't take long for Li Bingtian to come back with everyone with a strange face, and he made a mistake again!

This time, Li Bingtian didn't have any analysis or analysis, and he didn't have time to rest with the scientific expedition team, so he greeted and led everyone into the corridor again.

The start of this time was not bad, the scientific expedition team walked along the right path for a long time, killed several waves of monsters blocking the road, and was about to successfully get out of trouble, but who knows, and I don't know when, the compass shows that everyone is going wrong again!

Considering that it took longer to return the same way, Li Bingtian sighed and led everyone to continue to move forward!

After more than three hours, everyone walked through the corridor and suddenly found that after all their efforts, they returned to the old place again.

Although he knew that this would be the result, when he really saw the hall, Zheng Ya's heart also had a deep sense of helplessness, how could it be like this?

Is it true that you can't get past this hurdle?

Li Bingtian squatted on the ground, kept making comparisons, and after calculating for a long time, Li Bingtian sighed and said: "What a strange corridor, my calculation is absolutely not wrong! How can it be that every time we are about to succeed, an invisible hand will stretch out from inside the ancient tomb to redraw the direction of the corridor, so that we can return in vain!" ”

Hearing Li Bingtian's exclamation, several other companions surrounded him, and Tuoba Yanqiong said, "Professor, what you mean is that someone is deliberately making trouble for you." ”

Li Bingtian said with a wry smile: "It shouldn't be a troublemaker, I'm also a metaphor......

The two people who spoke spoke very casually, but Zheng Ya's heart suddenly moved, a golden light flashed in his eyes, he gently turned on the function of the geophysical detector, and after carefully probing it, he said to Li Bingtian without moving: "Professor, let's continue to go in and give it a try, it is estimated that we failed to fully implement your instructions, let's try a few more times, and if we don't succeed." ”

Li Bingtian was stunned for a moment, looked at Zheng Ya, and saw Zheng Ya with a calm face, as if Zheng Ya thought so.

Without asking too much about the situation, Li Bingtian led the expedition team to enter the corridor again.

Standing at the mouth of the corridor, Zheng Ya said in a low voice: "Professor, come here, let's wait a while before leaving, please pay attention to the changes in the geophysical prospector." ”

Everyone in the expedition team remained motionless and waited quietly at the door of the corridor.

After a while, Zheng Ya's face was strange, and his hand pointed to his compass, Li Bingtian looked at the geophysical pointer, and suddenly found that the direction had completely changed, even if everyone did not move, it seemed that the corridor was constantly changing.

didn't speak, and after Li Bingtian came over, Zheng Ya called Wu Qing again, and said in his mouth: "Brother Qing, let's discuss and discuss together." ”

After Wu Qing came over, Zheng Ya, Li Bingtian and Wu Qing squatted on the ground and said a few words in a low and cryptic voice, Li Bingtian and Wu Qing glanced at each other and saw the surprise in each other's eyes.

In the end, Li Bingtian said: "Okay, then let's wait a few minutes, go back and come again, and enter again." ”

Yi He and Tuoba Yanqiong didn't know what the three of them said, but they didn't ask much, and after a few minutes, everyone returned to the hall, and suddenly found that the passage they had entered had changed direction again.

After coming out, Li Bingtian began to observe again, and walked to a gate, and said loudly: "Zheng Ya, Wu Qing, you also come over to take a look, I may have made some discoveries......"

Zheng Ya and Wu Qing walked over from two different directions, a little far away from Li Bingtian, and stood up straight, Li Bingtian said with a smile: "I found ......"

The titanium-osmium alloy long stick in Zheng Ya's hand suddenly flashed with golden brilliance, and he slammed it down with a stick in front of him......
