Ding Qin glanced at the team preparing for the test flight again, "First of all, I want to thank everyone for their support and courage. However, I just tried it, and the glider is extremely affected by the air currents during flight. This big cliff, the specific air flow is unknown, the distance is unknown, we can't take such a risk. ”

Feng Lei thought for a moment and said, "However, we have to conduct such an experiment to determine whether we can pass through the Jinsha Great Cliff. ”

Ding Qin said, "You can't use people to test. If something goes wrong, we can't fix it. ”

He looked around, "Let's replace it with a heavy object." I also tried it just now, and above the glider, if there is no air flow, the control of the direction is not very demanding. If there is an air flow, you can't control it even if you want to. Therefore, it is much safer to use heavy objects instead than people. ”

Feng Lei heard Ding Qin say this, and the doubts in his heart suddenly disappeared. "Yes, yes. When someone comes, immediately prepare supplies equivalent to the weight of ordinary people. ”

Ding Qin actually raised his hand again and stopped Feng Lei's order, "You don't need to prepare supplies." I look over there, I have a lot of stones. Let's wrap some stones. We have limited supplies, and no matter what they are, it is difficult to replenish them if they are lost. ”

Feng Lei nodded after hearing this, and sighed in his heart that Ding Qin was meticulous. Soon, the soldiers brought some stones, wrapped them in cloth, and even made them into the general shape of a person. After checking the packaging and strapping several times, the dummy was loaded on the glider and everything was ready for the test flight.

Ding Qin and Feng Lei worked together to lift the dummy to the edge of the cliff, the two looked at each other, counted to three together, and then worked together, just like Ding Qin started from the ground, sending the dummy into the air.

Although it is said that the dummy cannot use spiritual power to control the formation above to extend the flight distance and control the smoothness, because Ding Qin and Feng Lei are faster than Ding Qin taking off by himself when they exert their strength, they can basically simulate the entire flight process.

If this dummy can successfully reach the other side of the cliff, then there will definitely be no obstacles to changing to a real person.

So, as soon as the dummy flew, everyone here held their breath almost at the same time, watching every slight change in the dummy's air.

During this time, the airflow is smooth and there is no wind. The dummy's flight route was basically the same as expected, and it seemed that it had already crossed two-thirds of the cliff and was about to land on the opposite bank.

"It seems that we have found a way to cross the cliff. Feng Lei breathed a sigh of relief, listening to the tone, his heart was already nine out of ten.

However, Ding Qin's expression has always remained serious and cautious.

As soon as Feng Lei's words fell, a slightly grayish-black air flow suddenly shot out from the cliff, directly hitting the glider. The rocks scattered in an instant, and the glider made a few irregular circles in the air before crashing into the cliff.

"What's the situation?" Feng Lei involuntarily uttered. Many others in the team also exclaimed, and some even scolded, "Damn!"

Ding Qin frowned. In such a situation, he was somewhat prepared, because the bone soul had reminded him that such a big cliff could not rule out that there were demonic beasts that specialized in attacking things that passed through the air.

For under this cliff is a river. Where there is a river, there is water, and where there is water, there is food. It stands to reason that this should be a place with a high concentration of birds. However, after being here for so long, no birds have been found, which means that the safety of the air has been destroyed by something.

"It seems that it is still more troublesome to think about it. Ding Qin muttered as if talking to himself, "Why didn't the people who passed last time leave any information?"

Feng Lei shook his head. "In fact, a hundred years ago, people paid more attention to the effect of the strange soldiers. As for how the strange soldiers came to be, there may have been legends in the early days, but as those people slowly passed away, there was no news. But I think we should try another hang glider. ”

Ding Qin did not object. Although he knew that it would be futile to try more gliders, there was still a glimmer of hope in his heart.

To save material, they made a smaller version this time. The volume of the entire glider is only a quarter of the size of the standard, and the weight of the load below is only about a quarter of the average person.

When you are ready, the sun is already setting in the west. At this time, there is not even a hint of wind, and it is obviously the best time to fly.

Ding Qin and Feng Lei sent the glider into the air together, rekindling the hope of the entire team.

One-third, half-third, two-third.

As the flight distance lengthened, everyone's hearts had slowly risen to their throats.

"Whoosh". Again, the sound was similar to before, and there was a gray-black mist-like air current.

The flying device was hit again, shook in the air a few times, and crashed directly into the cliff.

This time no one spoke up. Enthusiasm in people's eyes has been replaced by loss. After two tests, the results were the same, which is enough to prove that there is something beneath this cliff. Trying to fly over it will only get the same result as these gliders.

"What should I do?" After a long time, Feng Lei turned his head, looked at Ding Qin and asked.

In this team, Feng Lei was accustomed to obeying Ding Qin's arrangement. Although he is much older than Ding Qin, firstly, he only escorts Ding Qin, and secondly, Ding Qin's plans are indeed always very practical, even excellent.

"Set up camp. Ding Qin didn't have any expression on his face, and even his tone was a little cold. In his heart, the mood has been extremely low.

He wanted to see what was going on now. However, it was getting late, and he could not allow himself or anyone else to take such a risk.

The night seemed to be very difficult. Ding Qin barely rested, and had been discussing with the bone soul how to cross the cliff in the sea of knowledge. The bone soul didn't have much advice on this, and in his impression, there was no such big cliff.

Of course, that doesn't mean the cliff doesn't exist. It may also be that the bone soul cultivation was already high at that time, and he didn't care about this cliff.

It is said that after the spiritual power reaches the third order, it can fly through the sky, up to 100 zhang. In that case, whether it is a cliff or a hidden demonic beast, it is not an obstacle at all.

As soon as it was dawn, Ding Qin came out of his tent. The entire camp was safe and sound, and there were no monsters attacking the cliffs. When he walked to Feng Lei's residence, he saw that Feng Lei was arranging for someone to connect all the ropes together.

"What is this for?" Although Ding Qin also had the idea of exploring the cliff with a rope, he could probably guess Feng Lei's intentions, but he still asked.

Feng Lei said, "Connect all the ropes." Each of us brought ten meters of rope, which added up to six or seven hundred meters. Moreover, the team also has a long rope of two hundred meters, which is eight or nine hundred meters when added together. Excluding the knots, it is conservatively estimated to be as much as 800 meters. Maybe, to the bottom. ”

Ding Qin sighed lightly, "I've thought about it too, but it's too risky." Not to mention that we don't know what's underneath, the weight of the rope alone is already huge. Even if we could fall to the bottom, there was no way to throw the rope from the bottom to the top on the other side. ”

Feng Lei said, "Let's go down and have a look." I'll go down in a while, and you'll wait up there. Before, the advance team went down only a few dozen meters, and did not find any demonic beasts in the air. This time, I'm at least looking for what height the monster is and what it is. ”

Ding Qin said, "I'd better go down." The trip was too dangerous. ”

Feng Lei said, "No, I'll go down." My cultivation is high, I have a lot of experience in marching, and I can handle situations easily. You're waiting for me up there with the big army. ”

After speaking, he turned around and called, "Come on! Get ready to explore the cliff!"

Ding Qin knew that Feng Lei had already made a decision, and it might not be easy to change. He could only sigh lightly, organize the others, and do a good job of fixing and loosening the rope.

As Feng Lei's body was slowly put down, the cliff exploration work officially began.

The number of ropes on the cliff slowly decreased, and Feng Lei had long been covered by the smoke-like air. Until the rope is exhausted, the strength on the rope does not decrease by half a point.

"What's the situation?" Ding Qin drove his spiritual power into his voice, so that it could travel farther. But he wasn't sure if Feng Lei could hear it now.

After waiting for a long time, there was no movement below. Ding Qin shouted again, but there was still no response.

Is it that the sound can't be heard?

Looking at the cloud-like air, I thought that this was also possible. If the clouds are too dense there, it is entirely possible to reflect the sound back.

"Childe, I'll go down and have a look. The leader of the precursor stepped forward and looked at the rope on the edge of the cliff, "We were a little negligent just now. This time I brought a few flares down, and if there was danger, I would use one red flare, and if there was no danger, I would use two green flares. Our signal ejection can be two or three hundred meters high, and it may be able to transmit information. In addition, when the flare explodes, the sound is extremely sharp, and it can also be used for communication. ”

Ding Qin nodded, "Okay." Then you should be more careful. ”

The leader of the prefect team saluted Ding Qin, took the signal flare and other objects with him, and slowly climbed down. Every 100 meters or so, he went up to talk to Ding Qin. However, when he reached about 400 meters, he entered the fog, and his voice weakened significantly, and further down, the sound could not be heard at all.

It seems that it is indeed the cause of the cloud.

Ding Qin slowly calculated the distance of the descent according to the speed at which the leader of the prefect group descended at this time. After waiting for a while, it was estimated that the leader of the precursor group had reached the end, and he checked the tightness of the rope again.

Both should still be on the rope.

Soon, under the clouds, two faint shades of green appeared. It was a few more moments before two faint voices came from below.

Whatever they found, at least it's safe now.

Ding Qin breathed a sigh of relief. I was about to ask someone to pull the rope up, but I obviously saw that the pine nuts were slightly loose.

Later, the person pulling the rope suddenly shouted, "Oh no, the rope seems to have failed!"
