When Feng Yan saw the young men's circle of friends, Fat Tiger had just completed the second real-time main quest.
5 minutes ago.
After Fat Hu received the second real-time mission of the main line, he felt that the system was looking for trouble with him, and after receiving the prompt message, his favorability towards Feng Yan dropped a lot again, although the copy was only less than 5 at the beginning. Minutes, but he seemed very unhappy that Feng Yan hadn't come to save him yet.
"What are you doing? Do you want me to challenge difficult tasks one after another just to cover up that guy named Yanfeng's lack of ability and delay in coming to save me? Is he the master or am I the master?"
The difficulty of the second real-time task is obviously much greater. First, the water rises faster, and secondly, the whole incident returns to the original point, that is, the valve at the bottom of the pool must be opened.
And if you want to open the valve, you have to go back to the problem of finding the key.
"I just guessed it might not be that simple."
The reason why Fat Tiger has such an idea is because the water is still in the pool, and the hard mode dungeon will not let something like this that can cause chaos for players continue to exist without doing anything. Facts have proved that Fat Tiger’s guess was completely correct.
"Okay, don't panic, don't panic."
Fat Tiger forced himself to calm down, ignored the rising water level, and thought again.
To successfully solve puzzles, the prompts given by the system and environment are very important, so the first thing to do is to interpret the latest prompts of the system.
Obviously, as mentioned in the prompt, what is being poured into the pool from the water outlet at this moment is no longer water, but an unknown liquid. This unknown liquid may be the key to solving the mystery.
Unable to figure out what this unknown liquid was for the time being, Fat Tiger decided to look for the valve first. In his opinion, solving the mystery of the unknown liquid was the key. Of course, the location of the valve must also be clarified.
"At present, it seems that the key and the unknown liquid are the key points. In other words, the location of the valve should not be too difficult to find. Let's search the center and four corners of the pool first."
It went very smoothly. Fat Tiger staggered in the water towards the center of the pool, where he kicked the valve and shivered in pain, losing a little of his health.
By now the water had reached his stomach, just shy of reaching his chest.
Taking a deep breath, Fat Tiger dived into the water. The water was very turbid. Of course, he didn't dive in to see, but to touch the size and outline of the valve with his hands.
After touching it twice, Fat Tiger probably knew the style of this valve.
This should be a large rotary valve, probably as big as a basin in diameter. There are many nuts and an iron device fixed under the valve ring. It seems that it should be an outlet for large amounts of drainage. There was a very delicate keyhole on the side. Fat Hu touched it with his hand. The hole was very small, similar to the keyhole of a bicycle chain lock. In other words, if there was only one key in the pool, he wanted to find it. , almost like finding a needle in a haystack.
He tried to turn the valve port hard, but the valve didn't move at all. It seemed that he really needed the key.
After returning to the surface, Fat Tiger had no clue for a while. He found the valve, but it was useless without the key.
The water level was rising rapidly. In just one exploration time, the water level had already reached his chest and reached his collarbone.
Dry waiting became more anxious, and Fat Tiger simply started to explore randomly. He used his hands and feet together, sometimes exploring with his feet, and sometimes he plunged into the water to explore with his hands.
But obviously he didn't understand the key point of the puzzle. It was impossible to find the key by groping randomly.
The water has reached his neck. As mentioned earlier, in this case, the water does not need to reach the player's head. As long as it reaches the neck, the player will start to panic and lose basic thinking ability. If it reaches the chin, It basically declares the game over.
The same goes for Fat Tiger. He started to panic. If he didn't think of a way, he would really die.
"There must be a way, there must be something, wait, what does this smell like?"
Just when Fat Tiger was about to give up, he smelled a smell. He was very good at chemistry. After a little identification, he knew what kind of smell it was.
"Hydrogen peroxide!"
Hydrogen peroxide, whose scientific name is hydrogen peroxide, is an oxidant. The concentration depends on the ratio. The concentration for medical use is generally low, while the concentration for industrial use is much stronger.
"Hydrogen peroxide...Hydrogen peroxide...In other words, the unknown liquid discharged into the pool is hydrogen peroxide. Judging from the smell, the concentration is quite high, even exceeding the industrial concentration. So why should it be discharged into the pool with such a high concentration? Where’s the hydrogen peroxide?”
The answer is definitely not to play with Fat Tiger, so there must be other uses.
"There must be a hint. Yes, there must be a hint in the front that can be linked to hydrogen peroxide to solve the puzzle successfully. What is it? Ah wu..."
While he was thinking, the water had already reached his mouth. Perhaps this was because of the system's deliberate decision. Fat Tiger's foot slipped and he fell. He immediately fell onto his back in the pool, and the water instantly enveloped his entire body. .
Fat Tiger suddenly started to flutter crazily, and finally jumped up to the surface of the water. He jumped hard and took a deep breath, and then sank to the bottom of the water again. At this moment, he realized that it was useless. The height of the water was already higher than his body.
The only time left for him to think now was his last breath.
And ordinary people can hold their breath for more than one minute, which is already very powerful.
After they were all immersed in the water, Fat Tiger was no longer so panicked. He closed his eyes tightly and began to recall things in his mind like lightning. The content he wanted to recall was related to hydrogen peroxide.
It was relatively quiet in the water. Fat Hu calmed down and quickly thought of something mentioned in the system explanation when he first entered the dungeon.
In the explanation of why he is here and how he and Feng Yan are masters and disciples of a charlatan and a liar, when the valve is mentioned, the modifier "iron valve" is given in front of it.
It was as if a starlight instantly ignited Fat Tiger's inspiration.
"I understand that hydrogen peroxide has the effect of accelerating the rust and corrosion of iron products. If the concentration is very high, it can cause iron to rust in just a few minutes. The valves are made of iron, and the nuts of the fixing devices are also made of iron. It's made of iron. If it rusts too quickly, the iron filings will fall off. If the falling off is serious, you can just pry it open. You also need to find a ball key."
Thinking that nearly half a minute had passed, Panghu felt a little tight in his chest, but after understanding the key points, his spirits perked up.
With this thought in his mind, he slightly identified the direction and swam towards the position of the valve just now. When he came to the valve mouth, Fat Tiger held the valve mouth with both hands without turning it. He used the buoyancy to pull it up directly. Unexpectedly, with one pull, the entire valve device became somewhat loose, and at this moment, he clearly felt that the valve port, which was relatively smooth just now, was already very rough, and it must be rusty.
Fat Tiger was overjoyed, knowing that his guess was correct. All he had to do next was to pull out the entire valve device and go find the key.
With a fierce heart, Fat Tiger used all his strength, and finally completely destroyed the valve when he was about to choke to death. The entire valve device was completely rusted and was completely opened by Fat Tiger.
Suddenly, a suction force came from the valve mouth, and water rushed towards the valve mouth. Fat Tiger's crisis was not resolved yet.
Since the size of the valve port is limited, the suction power is limited, and the drainage speed is limited. Although the speed is okay, it still requires the player to endure it for more than 20 seconds before the water level drops to a position where breathing can be resumed.
Fat Tiger didn't even have a breath, and the simple system settings were somewhat humane. When Fat Tiger couldn't stand it anymore and was about to start breathing, he lowered his health instead of breathing, and finally survived those twenty seconds. .
Because he was well aware of the dangers of high-concentration hydrogen peroxide, Fat Tiger kept his eyes and mouth tightly closed throughout the process, and did not start breathing or opening his eyes until he was out of the water source.
After all, all the water was drained out of the valve, and Fat Tiger was already slumped at the bottom of the pool. He was breathing heavily. Before he had time to rejoice, the system's real-time tasks were updated again.
