Chapter 18 New Clues

"Is this '1' or 'I'?" Yue Yinshi came to Cao Bo and then looked at the coin in his hand. Sure enough, a blue oil trace ran through the coin and was evenly divided into two parts by the crease.

"Can it be another situation?" Cao Bo simply bandaged his wound, and then looked over and over at the coin folded 60° and the trace written on the inside of the coin, but he didn't find anything special for a long time.

"Why don't we find out if there is anything similar? I just counted it roughly, and that guy launched at least six or seven attacks!" You Zhenghui looked around and proposed to find out if there were any other clues.

And it's hard to say whether the things on this coin are left by SD-019 for them, because as a colonist, there is no reason to leave anything for Cao Bo, because the two sides are natural enemies that can't coexist.

However, with a glimmer of hope, Cao Bo and the three of them still carefully searched the nearby ground. He still remembered the two times when they attacked Cao Bo at the beginning, and Cao Bo immediately found the place of the accident, because the Korean student with an injured thigh was still lying on the ground in pain.

"Action should be quick, otherwise it will be difficult to find these things when the police and ambulances come!" Cao Bo took the lead in running to the boy, and then untied his belt and tied it to the other party's thighs. Because there was a lot of blood flowing on the ground under the student's buttocks, Cao Bo was worried that this person would lose too much blood and die after a while.

"Don't worry, I'll treat the wound for you first!" Cao Bo did not hesitate and directly pulled open the other party's trousers. When he saw the wound inside, Cao Bo couldn't help but be surprised, because he saw that more than half of a one-yuan coin was falling into the student's leg muscles. Cao Bo estimated that the coin touched the bone inside, otherwise he would not have to go in at all with the strength at that time.

However, although the coin was still exposed outside, the coin was already slippery, and it was stained with blood. Cao Bo wanted to try it, but finally gave up. Because Cao Bo knew that he was working without disinfection equipment, the student's wound was very likely to be infected, and looking at the person's thighs were very thin. Compared with the extent to which the coin fell, Cao Bo inferred that the coin should be stuck in the thigh bone.

"Help, it hurts, my leg..." The Korean student was sweating profusely. At this time, there were several classmates around him. Although these people were all medical students, they seemed helpless when they encountered this kind of emergency.

Cao Bo had no scissors or tweezers around him. He turned over his pocket and took out a key from it.

Huh? When did you have this thing? Cao Bo looked at the silvery and strange-looking key in his hand and meditated for two seconds. At this time, he suddenly remembered that this was one of the gadgets that Deng Qi brought to himself!

At that time, Deng Qi brought some semi-finished products from the laboratory. Cao Bo didn't want to use them, because these things were really not safe to use, but Deng Qi finally insisted on putting the key in Cao Bo's pocket, saying that he would definitely use it sooner or later.

What is this thing for? As Cao Bo recalled, he pressed the button under the key. Sure enough, with a slight vibration, several small silver hooks of different shapes popped up from inside, and there was the longest '7' metal wire in the middle. At that time, Deng Qi's words also sounded in Cao Bo's ear at the same time.

"This is the most advanced master key. As long as you insert it into the lock hole and press the button below, the mechanism inside will automatically match the hook spring in the door lock..."

"If the lock is really rusty, don't be afraid. The metal wire in the middle is actually a micro welding and cutting machine. Although there is not much energy, it is more than enough to open one or two locks!"

Cao Bo was glad that he had such an ear at that time, otherwise he would be in a hurry now.

Cao Bo pressed the bottom of the key, and he found that the top of the '7' metal wire turned red in an instant, obviously with a very high temperature.

Originally, Cao Bo wanted to test it directly on the Korean student, but later he stopped and put the bent coin on the ground from his body, and then put the metal wire over.

'Ss~' Cao Bo didn't even react. He saw that the coin was drilled out of a small hole the size of an oil pen core. And Cao Bo stretched out his hand and carefully touched the coin. He felt that the residual temperature on it was not hot, and he couldn't figure out what the thing worked through.

Cao Bo did these things and was naturally seen by several Korean students next to him. They knew less than Cao Bo, and they just showed a surprised expression.

"Cao, what is this?" When Cao Bo heard this tone, he was so familiar with it? Looking up at the man, he had really seen it a few days ago, and Jin Hongen's whereabouts were dug out of his mouth.

"It's great to see you!" Cao Bo did not answer the other party's questions, but asked them to hold down the injured.

"Maybe it will be a little hot, but if it is delayed for too long, I'm afraid you will hang up." Cao Bo didn't care whether these people understood what 'hang up' meant, but Cao Bo was still very gratified to see these people's help. After all, this group of people can still help themselves.

Cao Bo has had an experience just now, so this time it is easy to open the coin that fell into his thigh. Although Cao Bo had just tried the coin with his hand and it was not hot, the Korean student's muscle tissue was more **, which made him twitch all over. But to Cao Bo's surprise, the man did not make a sound, but his lips were bitten by himself.

"Good job, I didn't expect you to be quite strong!" Cao Bo sincerely praised, and then he looked at the guy closest to him, who had always called himself 'Cao'.

"What's your name?" Cao Bo didn't look at the other party's face, but just stared at his hair. Although this guy's face was full of freckles, he had black hair, and these hairs were not only black but also thick, not only thick but also short...

"Zong Tianqiao." The man answered happily, "You need me, you say."

"Okay, since you said so, I won't be polite!" Cao Bo suddenly reached out and grabbed the other party's hair, and then pulled it down with a little force.

Song Tianqiao didn't expect Cao Bo to pull out his hair. He covered his head and shouted. Originally, he wanted to question the other party, but he saw Cao Bo twisting those long hair together.

"I don't have any tools in my hand now, but I have to take out this coin immediately." Cao Bo finally passed his hair through the small hole on the coin. At this time, he wiped his forehead and continued to say, "I don't think the ordinary thread can withstand such a large weight, but dozens of human hairs can withstand dozens of kilograms of tension."

"And your hair looks stronger..." Cao Bo pulled both sides of his hair with both hands, and then squeezed his mouth and lifted it up hard.

The boy had just endured for a long time, and finally shouted this time. It seemed that the coin did hurt the bone, so when Cao Bo pulled the coin up like this, the stingling pain of the bone made him unable to hold it any longer.

Cao Bo also has a headache, because he can imagine how painful it is. Now this person has shed too much blood. Although Cao Bo has the intention to knock him unconscious, he is afraid that this person will never wake up after this punch.

And Cao Bo felt that the coin was stuck. Even if it was done by a professional, the student might faint because of the severe pain, not to mention the most primitive method Cao Bo used.

"Hold on, look at Jin Haoyue coming to see you!" Cao Bo suddenly straightened up slightly, and when the boy below him heard Jin Haoyue's name, he immediately closed his mouth and tried to turn his head to look back.

At this moment, Cao Bo, taking advantage of the student's distraction, suddenly exerted his hands and shouted, "Go!" Unexpectedly, this coin was pulled out abruptly!

Despite the reaction of the people next to him, Cao Bo pulled Song Tianqiao over and tore his snow-white shirt one by one.

"Don't be stunned, come and help!" Cao Bo shouted, and several other South Korean students took these rags, and then simply tied up the student's injured leg, which could relieve his pain and better achieve the effect of hemostasis.

"Next, you should know how to deal with it. Loosen the cloth in half a minute and don't let his leg waste!" Cao Bo held the coin in the palm of his hand. He stood up and looked at Song Tianqiao, who blushed and white, and said, "Go back to the dormitory to change your clothes quickly, then call Jin Haoyue and tell her that someone needs to be taken care of!"

Cao Bo looked at the student with a cold sweat on the ground, and then nodded: "You're good. You're really strong!"

"Jin Haoyue is coming soon. If it's a man, just hold on!" Cao Bo's words were translated into Korean. It seems that the Chinese of the injured person is just average.

"Thank you!" However, the pronunciation of these two words thank you is still very pure. Cao Bo smiled and comforted the other party that it was not a big deal.

After Cao Bo left these Korean students, he opened his palms and glanced at the coins clenched inside. However, to Cao Bo's surprise, although the coin was full of blood, there were no other traces, let alone the letters written with blue paint.

Is it wrong to infer it? Is the horizontal bar on the coin just now just an accident? Cao Bo looked at it over and over again, but still found nothing in the end.

However, Cao Bo did not give up easily. After all, the colonist just now was very strange from appearance to disappearance. It definitely makes some sense for him to do so.

Sure enough, when Cao Bo dug up another coin on the asphalt not far away, he found that he had nothing.

I don't know why the coin has been rolled into a twist. The coin in Cao Bo's palm looks a little like the Arabic numeral '8' from the side.

And this coin was painted with blue paint. Cao Bo scratched his head after confirming it, because does it mean '0' or 'O'?

ps: The skills that everyone wants can directly reflect the characteristics of this person, the skills of Yue Yinshi... The fire does not want to repeat with others. Besides, his skill will be very powerful in the future, and now it is just a lack of actual combat and exercise.

Also, about the puzzles left by SD-019, you can guess whatever you want. With the development of the story, the mystery will be slowly solved.
