Not only that, but the limited space on the bridge deck and the bottomless darkness under the bridge combine to form a huge psychological pressure, and it is not an easy task to pass through this roadway.

After a little gasping for a while, everyone was hurrying to recover their rapid breathing, and Dai Mubai and Oscar, who were fisted, were not very good at this time, judging from their somewhat pale faces, the pain should be quite strong.

Tang San, who had recovered first, opened his mouth and said, "Through this temptation, we can determine three questions.

First of all, the speed of travel on the bridge should not be too slow, the time when you first step on the bridge deck should be a safe time, and we should move as fast as possible.

Secondly, there must be other mechanisms on the bridge deck, and our attention must not be focused on those metal fists, but we must always be on guard against our feet and forwards.

Finally, some changes have to be made to the connection of the tree and vine, and the current way is really a bit big for the interference before and after once someone has a problem.

Fortunately, the circumference of the metal bridge deck is not very long, and we can tie one end of the vine to our waist and the other end into a ring to cover the metal bridge deck, so that we can ensure that we will not fall completely. ”

After everyone nodded to show that they understood, Tang San was still very uneasy and demonstrated to everyone the specific operation process of the tree and vine knot.

At this time, Oscar, who had been lying on Oschin's body to borrow strength, suddenly hesitated and made his own voice: "When I fell down just now, with the help of the soul power light on the metal iron fist, I seemed to see the situation at the bottom of the bridge. ”

This sentence instantly drew everyone's attention to Oscar, and although Oscar is still not sure whether what he saw was really what he wanted, Oscar continued:

"The depth under the bridge should not be as deep as we see now, maybe only six or seven meters.

And judging by the reflection, there should be some flowing liquid underneath, not hard ground, and it feels like even if we do hit the ground, we shouldn't be hurt. ”

Oscar's words shocked everyone present, if the truth is really as Oscar said, their psychological pressure on walking on the narrow metal bridge can be reduced a lot.

For the sake of prudence, everyone is still ready to verify it, and it is not difficult to verify it if it is only six or seven meters away.

At the end of the line, Oschin quickly turned and ran out of the tunnel, and after about five minutes, Oschin returned with a stone the size of a human head, which had been tied to a sturdy vine long enough.

Reaching the edge of the platform, Oschin threw the stone in his hand into the seemingly bottomless space under the bridge.

It must have taken less than a second for everyone to hear the obvious sound of entering the water, followed by the sound of the stone colliding with a hard object.

Oschin tried to drag the vine in his hand again, but the stone did not continue to fall, and it was obvious that it was really finished, so Oschin retracted the vine in his hand upward.

"Huh" looked at the stones that had been tied together by the vines, and Oschin let out a soft sound in a little surprise.

The stone is wet, and that's fine, because I could hear the sound of the stone entering the water very clearly, and it would be strange if it wasn't wet.

It's just that the liquid that still hangs on the stone is strange, and Oschin can be sure that it is not water, because water does not have such a viscous feeling.

The unidentified liquid, which still hung on the stone, gave Oschin the feeling of a colorless, transparent paste.

There must be a reason why things go wrong, and Oschin doesn't trust Flender to do something meaningless, and he feels he needs to figure out the meaning of the existence of these unknown liquids.

After carefully observing the small section of the vine stained with the unknown liquid, he found that there was no sign of corrosion or destruction on the vine, and Oschin boldly reached out and touched it directly.

"Slippery" was Oschin's first feeling.

Oschin was sure that the surface of the stone he found was very rough, and normally this rough surface would give people a very easy feeling of clenching, but now when holding the stone stained with an unknown liquid, Oschin actually had a strange feeling that he could not hold it hard.

Letting go of the stone, Austin tried to shake his hand again, but the unidentified liquid showed no sign of being thrown off, and it was obvious that it would be difficult to completely get rid of its interference in a very short period of time once it was stained with the unidentified liquid.

"The friction reduction is similar to soapy water, but there is a slight difference in viscosity, so what exactly is the purpose of this viscous version of soapy water?"

Oschin handed the stone in his hand to the others around him and asked them to try it out to see if they could figure out what it was, as he looked around and mentally analyzed the effect of the thing.

Suddenly, Oschin's gaze swept to the narrow metal bridge not far away, "Metal, narrow area, reduce friction" A flash of lightning slashed through Oschin's brain, and he understood the purpose of the teachers' actions.

"Sinister" was the first adjective that crossed Oschin's mind.

In the somewhat surprised eyes of Oscar and the others, Oschin walked briskly to the narrow metal bridge, stretched out his right hand with a sticky version of soapy water that had not shown any signs of drying up so far, and touched the bridge deck.

Sure enough, the friction has been greatly reduced, and now just touching the palm of his hand, Oschin has a feeling that once he wants to exert force, he will inevitably slip.

To be sure, they would have had a hard time standing on the narrow metal bridge if their shoes were stained with this sticky version of soapy water.

The most important thing is that this sticky version of soapy water seems to dry very slowly, which means that once someone has this sticky version of soapy water under their feet or body on the metal narrow bridge, it will not affect him alone, and this effect may even linger for several days.

Imagine that when someone falls down, he will inevitably come to the bridge with this sticky version of soapy water, then other people will also become more likely to fall off the bridge because of the sticky version of soapy water on his body, and when he comes back after falling off the bridge, he will bring more sticky version of soapy water and stick to the bridge, and eventually a vicious circle will be formed.

Considering the slow drying of this sticky version of soapy water, even if the time comes to the next day, the sticky version of soapy water on the narrow metal bridge that has not been specially cleaned will still make the students who are clean from top to bottom continue to be affected by it.

Standing up and rubbing the sticky version of soapy water off the stone wall in his palm, Austin told the other students who were looking at him curiously about his discovery.

After listening to Oschin's analysis, the corners of Dai Mubai and the others' mouths were all twitching, these teachers were really afraid that their task would be completed too easily, and they were simply changing tricks to increase the difficulty for them.

Not to mention anything else, let's just talk about their current situation, if Tang San hadn't prepared for them to have the vines tied to their bodies, then at least one of the eight people present now would have been covered with this sticky version of soapy water, which would have opened the beginning of a vicious circle.

Although his face became a little ugly, the training task still had to be completed, and now that a lot of time had been delayed, everyone could only force themselves to tie up the vines and prepare to go.

This time, everyone learned the lesson of the previous time, and in the first few minutes, everyone showed the fastest speed to move forward, and it was necessary to move forward enough distance before the Soul Guide was fully activated.

Two minutes later, Tang San, who was in the lead, once again reminded everyone that the high-pressure water column was coming, and the other seven people who had prepared quickly hugged the metal narrow bridge under them, and passed the first hurdle at the beginning without any danger.

Next was the Soul Power Light Card Blinding Flashbang, which marked the full activation of the Soul Guide, and the students who closed their eyes when the water column hit were not affected at all.
