The air is getting stuffy.

On both sides of the fields and riverbanks, the croaking of frogs seems to have tripled.

Tens of thousands of dragonflies flew from the surface of the river to the banks.

Tan Jianguo realized that there was only one moon in the sky, and not a single star could be seen!

"Oops!" Tan Jianguo, who knew the nature of Tiangong urine in the countryside, stood up, "There is a torrential rain!" And it could be flooding! ”

Jiang Xinjie frowned, "No..... the flood season of Lianshui River is not at this time!" And it hasn't rained in a long time! ”

"It's going to be a flood!" Tan Jianguo said, "Let's call the students back quickly, if it rains, the pontoon bridge will be very dangerous." ”

"Oooh." Jiang Xinjie also knew that now was not the time to be sloppy, so she hurriedly led the way to the river.

And many members on the shore also saw that the weather had changed, and ran down to inform those students before Tan Jianguo.

——

The history of the pontoon bridge is super long.

The first Yellow River bridge and the first Yangtze River bridge were both pontoon bridges.

Because the pontoon bridge is simple to make, the cost is less, the time is less, and it is very tough!

The principle is to find a wooden boat or large box of the same volume to float on the water, connect the boat in series with two or four iron cables, and then lay iron plates or planks on the boat or large box.

Because the wooden boat and the large box are constantly changing in height with the water level, the bridge head is generally placed with transition beams or springboards, and the ship also needs to install cables that can be flexibly stretched.

And some rivers are too different from the water level in the flood season and the dry season, so there are lifting platforms on both banks.

That's the end of it.

The water level of the Lianshui River is so high all year round, even if it is a big water, it has not flooded both banks, so the anchor ingot of the pontoon bridge (that is, a very heavy piece of iron, buried in the soil in a fixed position) is on the shore, and four anchor ingots drill out of the ground four small iron pillars, where the gangplank is placed.

When Tan Jianguo dragged Jiang Xinjie to arrive, a member of the club who understood the weather omen had already explained it clearly to the students standing on the springboard.

The student also knew that the rain was not a trivial matter, so he passed on the news that the flood was about to be sent in the same way as the tiles and built the house, and walked to the shore one by one, in an orderly manner.

Tan Jianguo looked at the surface of the water, and then at the speed of the students, and felt that it must be in time, so he relaxed.

Now that there are students always passing by, Tan Jianguo must be cautious when speaking, so he just smiled and nodded with his classmates, smiled and greeted, and didn't say a word else.

After about ten minutes, there were no more students on the pontoon, and Tan Jianguo's face finally eased a little.

Tan Jianguo looked in the direction of Broken Dragon Beach, but thinking that with Zhou Kailu by Zhang Lu's side, there should be no accident.

And...... It's been so long, and Zhang Lu's side should be finished.

He pulled Jiang Xinjie and wanted to go downstream to meet Zhang Lu, and then go back to the guest house.

At this time, I saw that the students who had reached the embankment were shouting into the middle of the river.

Tan Jianguo raised his eyes to look, but he couldn't see anything in the dark, which surprised him very much.

When I was on the embankment, I had a good view and could see the entire bank, but now on the horizontal plane, it was pitch black, but I could only see a quarter of the distance.

"There's fog in the middle of the river." Jiang Xinjie frowned, "It seems that it is really a heavy rain."

It turned out to be foggy, Tan Jianguo frowned, no wonder he couldn't see far.

The two of them didn't suspect him, and they still came to the beach together, but it was the students who were shouting something in Xiangxiang dialect to the other side.

There are so many people that they shout and talk together, so you can't hear what they are saying at all.

Tan Jianguo stood in front of them and didn't know what they were saying, let alone the other side.

However, Jiang Xinjie's face suddenly changed, "Brother Tan, they said that the students of Dongshan School are still on the pontoon. ”

"What?" Tan Jianguo turned around suddenly, "Why are they still on the pontoon?" ”

Jiang Xinjie hurriedly pulled over a student to ask about the situation, and said with a complicated look: "They ......"

"I can understand Xiangxiang dialect." Tan Jianguo's face was bitter.

It turned out that those students said: The guy on the other side actually thought that these students who demolished the school tricked them into going down the bridge in the name of making a big flood, so they refused to get off the pontoon bridge.

With this IQ, how can you be a student? Tan Jianguo took off his clothes and handed them over to Jiang Xinjie's hands, "I'll go to the middle of the river to explain the situation to them, they don't believe these students, they should believe me, a middle-aged man, right?" ”

Jiang Xinjie dragged Tan Jianguo's arm and said, "Brother Tan, don't go, it's dangerous." ”

"Remember what the newspaper said I was from Xiangtan?" Tan Jianguo touched Jiang Xinjie's head with a smile, "I'm just a hero." ”

Jiang Xinjie was so little by Tan Jianguo, and suddenly felt that she had a special face under everyone's gaze...... Felt...... The current situation of the two people is also very similar to romance, just like that kind of tragic ...... Singing and crying stories...... It's said that it's sadness, and the fate of the actor is definitely not good.

Jiang Xinjie had just pulled out her reason from being moved and figured out this joint, and Tan Jianguo had already gone to the river.

——

It's like filling a lake of boiling water on the river, and the fog on the entire lake rises in an instant, and Tan Jianguo was caught off guard and was overwhelmed by the fog.

Of course, Tan Jianguo didn't feel it, in his eyes, there was already fog on the river, and it was already dark in front of him.

He groped his way through the darkness when he was suddenly startled by a loud "gurgling" sound.

As soon as Tan Jianguo got on the bridge, he suddenly heard the "gurgling" sound of the water boiling, and looked into the river, isn't the water like boiling?

Don't...... Where did this sudden fog come from? Water vapour?

Tan Jianguo suddenly remembered something, yelled badly, and hurriedly ran to the middle of the bridge, where there were still cheers from Dongshan students celebrating the victory.

But in Jiang Xinjie's eyes, as soon as Tan Jianguo stepped on the springboard, the entire pontoon bridge was immediately covered by the rising white mist, like a fairyland that suddenly appeared.

"Brother Tan!" Jiang Xinjie shouted anxiously, but did not hear any response, so she wanted to go down the embankment to pull Tan Jianguo back.

But some students were already staring at her, and they repeatedly pulled her to prevent her from going down.

"You let me go...... Put ......"
