Xue Congliang was a little short-sighted, and it was even more difficult to see things between the mist, he originally thought that he was overworked, resulting in dizziness, but suddenly heard the voice of the white light, and only then did he believe that his eyes, what he saw, were real.

This white light only came out again after disappearing for so long, and Xue Congliang felt a little embarrassed when it came out in this place.

"White ...... Mr. Bai, why did you appear in this place? I feel a little embarrassed. Xue Congliang said a little nervously while rubbing the foam on his body.

"Hehe, what's so embarrassing about this, it's a man at the same time, you have it, and everyone else has it." Mr. Bai's voice sometimes sounds very strange, and men and women can't tell the difference, so sometimes, Xue Congliang listens to the voice of the white light, like a woman's voice, and also like a man's voice, and sometimes, men and women can't tell the difference.

"Oh, these few days, it can be described as tragic, so many people have died, I feel a little sad in my heart, there is no need to die so many people, in fact, many of them have agreed to join me." Xue Congliang said to himself, spraying back and forth on his body with a sprinkler, and the dust that was rubbed off was like a mud pill, rolling down with the flow of water.

"These people are innocent! Actually, you understand wrong, not only did these people not change their minds, but at the same time, with several other people, they are all the same dogs, they are just not defeated as subordinates, see the right time, and protect themselves, do you know? ”

"But......" Xue Congliang still wanted to say something, but. What's the use of talking about this now, it's completely unnecessary, all of this. It's all in the past.

"Okay, these things have passed, and now, the most important thing is to save Xue Tan, and in two days, Xue Tan's water source. It will pollute the groundwater, and the quality of your water here for centuries will be polluted like never before. If the groundwater is polluted, it will not be until 100 years from now. "Mr. Bai said very seriously.

"Huh? A hundred years later, so terrifying? The well here. Isn't it about to face the catastrophe of annihilation? Xue Congliang heard this. Frightened, he suddenly turned off the faucet, because the water in the faucet was drawn from the ground.

"Don't be in a hurry, there is still room for salvation." "But you need to hurry, we're waiting for you......"

After all that is said. This white light slowly disappeared between the mist. Xue Congliang also finished taking a bath, and the mist in the bathroom disappeared a lot.

After Xue Congliang wiped the water droplets on his body with a bath towel. The conversation just now is like a world away.

But Mr. Bai's words are still lingering in his heart, yes, the depth of Xue Tan will definitely connect to the groundwater, if the groundwater is polluted, the consequences will be unimaginable. The pollution of surface water can be solved by the circulation of water bodies, and once the groundwater is polluted, all this is irreversible.

Xue Congliang took a shower, breathed a sigh of relief, put on loose clothes, and took a nap in his office. It just so happens that no one is coming to him for work now. Actually, he didn't know that Li Meiyu had already instructed everyone not to disturb Xue Congliang during this time, he needed to rest sufficiently.

He was so tired that he was lying on the sofa, and before he knew it, he had fallen asleep.

When I woke up, it was pitch black outside, and there was the chirping of crickets all around, chirping, chirping, chirping, chirping, It turned out that the watch on the wall had already pointed the hour hand at eleven o'clock, which was nearly midnight.

This long-lost cricket cry made Xue Congliang suddenly feel a lot more energetic, back then, when he was young, he listened to such cricket chirping and fell asleep. Now, it's been a long time since I've heard such a familiar voice.

He got up gently, as if he was afraid of disturbing something, in fact, he slept alone in this room, where could he disturb others.

Looking into the distance through the window, I saw a room lit up in the distance. This is Mr. Du's room, this expert in cracking supernatural events, I don't know what he's doing, why haven't he slept yet?

With a "squeak", Xue Congliang opened the door softly and walked out.

Outside, the night is like water, and all kinds of insects on Fulong Mountain are holding a grand concert at night, with the cries of weavers, crickets, earthworms, and all kinds of insects that cannot be named, and occasionally fireflies light up their small lanterns, flying around in the night sky, drawing beautiful arcs.

Xue Congliang gently knocked on Mr. Du's door, only to see that Mr. Du was still fighting at night.

"Hey, the position of this sensor is a little wrong, forget it, it doesn't affect the use, and the image is still clear." Mr. Du didn't greet Xue Congliang either, and immersed himself in his invention.

Xue Congliang saw that Mr. Du's underwater photography robot had been assembled for the most part, and he was like a small dolphin, with two eyes being ultra-high-definition cameras and his mouth being an underwater terrain detection device. What is in the ground, you can see it clearly.

Moreover, the careful Mr. Du also installed a high-brightness lighting device on this thing, which looks really good. When Xue Congliang saw such a high-tech thing, his interest was immediately aroused.

"Wow, Mr. Du, you are really a genius, flying in the sky, swimming in the water, you can do it all, and now, you almost run on the ground and you can't do it." Xue Cong said with a sigh.

"Hmph, how can you run fast in the sky when you run on the ground, so I'd rather improve the performance of flying in the sky than develop the running on the ground, because running on the ground is too risky, the terrain on the mountain is complicated, and if you're not careful, this thing will be smashed to pieces." Mr. Du didn't feel sleepy at all, he said energetically.

"Oh, I see, in fact, running on the ground can be replaced by your rotorcraft, the aircraft is easy to move, and the speed is extremely fast."

"Of course, that's why I'm now concentrating on developing technologies that improve the performance of the aircraft. At that time, the stability of this aircraft will be greatly improved. Flying in the air, as if walking on the ground, you put your glass of water, and this glass of water will not be spilled. Mr. Du said proudly.

"Ah, really? That's pretty impressive, isn't it? Xue Congliang was really amazed by this old Mr. Du's skills.

"Well, I've been studying this thing all my life, but it's a pity that people are old, they can't do a lot of things, their heads are a lot stupid, and they can't remember a lot of ideas. The young people of your generation are bent on making money, and you are not interested in this kind of high-tech, so up to now, there have been no major technological breakthroughs, only me, an old bone, has gone into battle to engage in research and development. Mr. Du sighed.

He said that this is indeed the case, nowadays, the world is declining, especially young people, all of them are in the eyes of money, and who else is desperate to engage in technology, all of them are salesmen, and they are all selling products on the street. And those products are also shoddy and harmful to others, and it is difficult to find even a fine product.

Xue Congliang felt that he was still a qualified young man. Although he is also bent on digging in the eyes of money, hunting for treasures everywhere in the mountains, he has never left his medical career, earned so much money, and dug up so many treasures, in fact, it is completely for the purpose of curing diseases and saving people. Xue Congliang consciously did a good job.

"Okay, let's not talk about that, it's useless to say it. Let's talk about this thing. Mr. Du took off his reading glasses from the bridge of his nose and showed the underwater robot to Xue Congliang.

Although this thing is not large, it is the size of a normal bucket, and the length is more than half a meter. The shape is streamlined. The weight is estimated to be around twenty pounds.

"It's not light, it's ten times worse than your aircraft." Xue Congliang said.

"That's for sure, you can imagine that this thing is swimming in the water, and if the weight is too light, it may be lifted up by the buoyancy of the water, and it will be more difficult to dive."

Unexpectedly, after Mr. Du's careful design, this thing has the function of diving in addition to the shooting function.

"How deep he dived?" Xue Conghao asked curiously.

Mr. Du found the calculation table on his desk, and then, affirmatively, "This guy has no problem diving thirty meters underwater, if it is deeper, he will probably be flattened by the underwater pressure." ”

"It's okay, it's okay, the water in Xue Tan, no matter how deep it is, won't exceed twenty meters, I estimate that below twenty meters, it will be a black piece." Xue Congliang thought for a while and said.

"Of course, do you find it, the eyes of this robot, the left eye is a general high-definition camera, and the right eye is an infrared high-definition camera, if the underwater light is too dark, we can use the remote control, activate the infrared camera, which can see underwater objects clearly." Mr. Du said happily.

Xue Congliang looked at this high-tech thing, thinking about the 10,000 yuan he spent on it, it was actually worth it. This thing, ordinary people really can't make it, it seems that the price that Mr. Du gave himself is still a friendship price.

"Okay, once we've installed the high-energy battery, we're ready to go, and we can start experimenting." Mr. Du, looking at his work, said happily.

"Old Du, it's one o'clock in the morning...... Xue Congliang reminded.

"Ah, no, it's early in the morning? I hadn't looked up outside this afternoon, and the time was running out so fast, I thought it was evening! ”

Xue Congliang had to sigh that he was a workaholic, and this Mr. Du was also a workaholic...... (To be continued......)
