The man with the short hair looked as cold as ice. He was angry, really angry!

A good game was lost to Sun Shu. If he didn't get rid of him, he would not be able to escape in peace. He brought people to attack from the front and back, and his attacks were getting more and more fierce. No matter how strong Sun Shu was, he couldn't resist the attack of six or seven people and protect others. Soon, he felt something passing in front of him, but he didn't bother to look down, so he went to block the next attack.

Wang Youlin was no longer the playful man he had been before. His face was full of gloom and every move he made was aimed at the vital points. He didn't look like a young man in his twenties at all. "You deserve to die!"

He lurked everywhere and finally got the two most important people, Gu Yan and Jiang Yier, but was destroyed by Sun Shu in one fell swoop.

Damn it, damn it.

Hei Hu, that idiot, should have been dealt with long ago.

Dr. Niu shouted at them, "Hurry up! It will be too late if you don't leave now."

But the crew cut and Wang Youlin were so angry that they didn't listen at all. They attacked madly, from the back, shoulders, and abdomen.

Sun Shu coughed up a mouthful of blood, and when the crew cut attacked again, he suddenly took out a pen and stabbed it into the crew cut's chest! Seeing that it was a pen, the man with a crew cut sneered and rushed forward regardless of the injury. When the sharp saber in his hand touched the flesh of the man in front of him, he slashed it back with his backhand. The next second, he screamed and covered his chest. Blood kept pouring out. He only had time to roar, "Be careful of the pen in his hand!"

Wang Youlin was frightened and changed his kicking action to kicking the pen, kicking the pen out of Sun Shu's hand.

Damn, beast!

What the hell is this research institute! So many tricks.

A disguise and a dagger disguised as a pen, is this a circus? !

Dr. Niu calmly asked someone to take back the weapon pen. He scratched it lightly with his fingers, and the cut was at least several centimeters deep. He immediately hid the pen in his pocket, "Go help them."

"Yes, Doctor."

The man in black approached quietly, and then attacked from behind, and the sharp blade pierced from back to front!

"Sun Shu!" Zhang Ze roared.

"Old Sun." In the remaining time, he saw Sun Shu being attacked from behind, and then being lifted up and walking towards the sea step by step. He was immediately furious, "Asshole!"

With a "bang", the sea surface was splashed.

"Boss!" Dong Shi roared, and rushed forward like crazy, killing whoever stood in his way, and soon killed him on the reef and jumped down violently.

"Boss..." Xishi clenched his fists on the ground. A man doesn't shed tears easily, but it's not the right time.

"This..." Su Wendong's face turned pale.

"..." He Mingyue covered her mouth, and her cold and beautiful face was also slightly pale at this moment: "The sea is so big, if someone falls in, they will be washed away and it will be difficult to find them."

"Ouch!" Xishi's body trembled slightly, and tears fell on the ground.

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

"Boss Sun..." Another man who stayed behind to protect him gritted his teeth, looking at Qin Hongfei's nonchalant look, he felt inexplicably chilled.

"It's still possible to save him." Qin Hongfei operated the little bee and dived into the seabed. After a burst of bubbles, the picture of the seabed was instantly displayed. It was not high-definition, but the specific location of Sun Shu and Dong Shi could be seen. They quickly came out of the sea and tracked in the air.

It was difficult for Dong Shi to save the injured Sun Shu alone.

Qin Hongfei collected the things and said, "Let's go."

Xi Shi was shocked, "Miss Qin, it's too dangerous."

Qin Hongfei said, "If it's too late, he will be washed away and can't be saved."

Xi Shi immediately fell into a struggle! "Let's go."

The sea is connected. Qin Hongfei chose a shortcut to avoid a head-on collision with the crew cut and took another path, which was also on the side where Sun Shu fell into the water. Qin Hongfei looked at the terrain, made a slight judgment in her mind, and grabbed Xishi who was about to get on the plastic lifeboat, "Tie a rope."

Xishi said hurriedly, "No need, I'm a good swimmer."

Qin Hongfei insisted, "Tie a rope!"

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

Behind her, the man looked around and felt it was unreliable: "This is not the place where Sun Tou fell into the water! Will it work?"

Qin Hongfei said, "Let's go to the place where he fell into the water now. Hei Hu and the others have not been dealt with yet. They won't let us rescue people and may even cause trouble."

"This is not the place where he fell into the water, but this is the closest to the place where he fell into the water." She looked at her watch, looked at Xi Shi who was about to fall into the water, and said, "Send two more people together. You have to search within a range of about one thousand meters, search along the east, and try to look for more places with rocks. Their current location should be roughly within this range." "

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

"How can you be sure?" Zhang Shao didn't trust her: "Let's go find the master..."

What if the calculation is wrong and we miss the chance to rescue!

His heart is heavy.

He Mingyue said, "She is right, it is roughly within this range."

Su Wendong said, "It can be calculated."

Zhang Shao: "Calculate? Can you calculate the speed of the water flow on the sea surface?"

Su Wendong and He Mingyue both looked at him, with an expression of why not.

Qin Hongfei squatted down and grabbed a handful of dust, "It's May now, there is no wind on the sea, probably less than level four..." He let go of his hands, "Did you see it?"

Zhang Shao: "..."

Qin Hongfei: "Don't understand?"

Zhang Shao: "..."

Who the hell can understand this!

Qin Hongfei explained, "Generally, wind force ratings are captured based on satellite meteorology, but they can also be detected manually. The static state is most obvious when there is no wind. For a light breeze, you can throw a leaf and judge by how fast it falls to the ground. Now, the dust I sprinkled can be blown up, which means there is wind. The wind force is medium, at least level three or four, because the small tree is not swaying. If the speed of the water flow is calculated based on the level three or four wind force, it is probably between 1.0 and 1.5 m/s."

"1.0 to 1.5 Vm/s is based on the flow direction and speed of the water density, plus the human factor of Dong Shi going down to rescue people and swimming back in the water, and so on..."

She quickly wrote out a formula.

The final answer is between 800 meters and 1,000 meters.

Zhang Shao: "..."

Looking at the complicated formula, he understood every symbol when it was separated, and when they were combined, they meant something.

Qin Hongfei didn't expect him to understand! It was written for her to judge. If it was correct, Sun Shu should be able to be rescued soon. If he couldn't be rescued within ten minutes, Sun Shu would fall into the sea with his injuries, and his life would be in danger.
