Back to 90s she made a fortune from scientific research

Chapter 497 can be counted.

Cun Tou's face was as cold as ice, he was angry, really angry!

It was a good game, and he was stuck at Sun Shu's side. If he didn't deal with him, even if he ran away, he would not rest in peace. He led people, attacked back and forth, and the offensive in his hands continued to intensify. He still needs to protect people from the flanking attack, and soon, he felt something passing in front of him, but he didn't bother to lower his head to look, and went to block the next attack.

Wang Youlin also no longer had the image of being playful before, with a cloudy face, and he shot at the vital point, not like a boy in his 20s should look like, "Damn you!"

He lurks everywhere, and managed to get the two most important people, Gu Yan and Jiang Yier, but in the end he was destroyed by Sun Shu.

Damn it, damn it.

Hei Hu, an idiot, should have dealt with this person a long time ago.

Dr. Niu shouted to them: "Go quickly! If you don't go, it's too late."

But Cun Tou and Wang Youlin didn't listen because they were red-eyed, and attacked wildly, back, shoulders, and front abdomen.

Sun Shu coughed up a mouthful of blood, and when Cun Tou attacked again, he suddenly took out a pen and poked Cun Tou's chest!Seeing that it was a pen, Cuntou sneered, and rushed forward regardless of the injury. When the sharp saber in his hand touched the flesh and blood of the person in front of him, he slashed hard with his backhand, and the next second, he screamed and covered his mouth. When he touched his chest, blood kept gushing out, and he only had time to roar, "Be careful with the pen in his hand!"

Surprised, Wang Youlin changed the action of kicking the person into kicking the pen, and kicked the pen away from Sun Shu's hand.

Damn it, beast!

What is this research institute!There are so many tricks.

Another disguise and a dagger disguised as a pen, a circus? !

Dr. Niu asked someone to pick up the weapon pen calmly, and lightly swiped his finger, and the cut was at least a few centimeters deep. He immediately hid the pen in his pocket, "Go and help them."

"Yes, Doctor."

The man in black approached quietly, and then attacked from behind, with a sharp blade piercing from back to front!

"Sun Shu!" Zhang Ze shouted.

"Old Sun." From the corner of his eyes, he saw Sun Shu being attacked from behind, and then being lifted up step by step towards the sea, his eyes turned red, "Bastard!"

There was a sound of "crash", and the sea surface was splashed.

"Boss!" Dongshi roared, and rushed forward like crazy, whoever blocked whoever was killed, quickly killed the rock and jumped down violently.

……

……

"Boss..." Xishi clenched his fists on the ground fiercely, the man did not flick his tears, but it was not time.

"This..." Su Wendong turned pale.

"..." He Mingyue covered her mouth, her icy face was also slightly pale at the moment: "This sea is so big, once people fall and wash away, it's hard to find them."

"Woo!" Xishi's body trembled slightly, and tears hit the ground.

"Don't cry." Qin Hongfei saw it and said.

"Boss Sun..." The other man who stayed behind for protection gritted his teeth, looking at Qin Hongfei's nonchalant expression, feeling inexplicably chilled.

"It can still be saved." Qin Hongfei manipulated the little bee and dived into the bottom of the sea. After a burst of bubbles, the picture of the bottom of the sea was displayed in an instant. It was not high-definition enough, but she could still see the exact location of Sun Shu and Dongshi. , and soon came out of the sea to track in the air.

With Dongshi alone, it is very difficult to rescue the injured Sun Shu.

Qin Hongfei put away the things, "Go, go over."

Xishi was startled, "Miss Qin, it's too dangerous."

Qin Hongfei said, "It's too late to be saved if it gets washed away."

Xishi suddenly fell into a struggle! "Walk."

……

……

The sea is connected, Qin Hongfei took a shortcut to avoid meeting Cuntou and the others head-on, and took another path, which was also on the side of Sun Shu's falling into the water. Qin Hongfei observed the terrain and made a little judgment in her heart. , grabbing Xishi who was about to board the plastic lifeboat, "Tie the rope."

Xishi said anxiously, "No, I'm good at swimming."

Qin Hongfei insisted, "Tie the rope!"

He Mingyue and Su Wendong were smarter. When they came over, they found a thick rope in the main hall, and now they helped Xishi tie it.

Behind him, the man looked around, feeling unreliable: "This is not the place where Sun's head fell into the water! Is it useful?"

Qin Hongfei said, "Go to the sinking point now, Heihu and the others haven't been dealt with yet, they won't let us save people, maybe they will make trouble."

"This is not the falling water point, but this is the closest to the falling water point." She looked at her watch, looked at Xishi who was about to fall into the water, and said, "Send two more people together, and you will search within a range of about 1000 meters. Search along the east, try to find as many places with rocks, their current position should be almost in this range."

"Okay." Xishi nodded, got on the lifeboat and went out, and said at the same time, "Zhang Shao, protect Miss Qin and the others."

"How are you sure?" Zhang Shao didn't trust her: "We'd better find the uncle..."

In case of a wrong calculation, the rescue opportunity is missed!

His heart was heavy.

He Mingyue said, "What she said is not wrong, it's almost in this range."

Su Wendong said, "It can be counted."

Zhang Shao: "Forget it? Can you calculate the speed of the sea surface current?"

Both Su Wendong and He Mingyue glanced at him, with expressions of why they couldn't.

Qin Hongfei squatted down and picked up a handful of dust, "It's May, and the sea is not very windy, probably less than level four..." Spreading her hands away, "Did you see it?"

Zhang Shao: "..."

Qin Hongfei: "Don't understand?"

Zhang Shao: "..."

Who can understand this!

Qin Hongfei explained, "The general wind power rating is captured based on satellite weather, but it can also be detected manually. The static state is most obvious when there is no wind. In a light wind, you can throw a leaf and judge it according to the speed at which it hits the ground. But now, the dust I sprinkled can be blown up, which means that there is wind, and the wind force is medium, at least three or four, because the small tree does not sway, and the speed of the water flow is about 1.0 to 1.5m based on the wind force of three or four. /s between."

"1.0 to 1.5Vm/s and then according to the density of the water, the speed in the direction of flow, plus the human factors of Dongshi going down to save people and swimming back in the water, etc. for reference..."

She quickly wrote out a formula.

The final answer is in the range of 800 meters to 1000 meters.

Zhang Shao: "..."

Looking at the complicated formula, he understands every symbol apart, and when combined together, there is something special.

Qin Hongfei didn't expect him to understand either!I wrote it for myself to judge. If it is correct, Sun Shu should be rescued soon. If he is not rescued within ten minutes, Sun Shu will fall into the sea with his injuries.

Suddenly, she felt as if she had forgotten something.
