Lin Yuan asked, "Tell me, what are we missing?" ”

Qin Peng said: "Battery, we lack high-performance batteries, lasers can't emit lasers by themselves for no reason, there must be an electric current to stimulate it, if you want to use it in engineering construction, then high-energy batteries are fine." ”

Lin Yuan thought for a while and said, "If you need a battery, what kind of battery is better to use?" Our lasers definitely need to be used for a long time, in that case, the battery that can not be used again after using it once cannot be considered, such as zinc-manganese batteries, silver-zinc batteries or something, only rechargeable batteries can be selected. ”

"There are many types of batteries that can be charged, such as lead-acid batteries, which are very commonly used in cars, and they are relatively simple to manufacture, but its capacity is somewhat small, and it is very troublesome to charge in a deserted place when building railways, and there are nickel-cadmium batteries, nickel-hydrogen batteries, both of which are large-capacity rechargeable batteries, but nickel-hydrogen batteries require special hydrogen storage alloys, which cannot be manufactured yet, so we use nickel-cadmium as raw materials."

Qin Peng said: "I don't know much about these, you don't have to discuss with me, so let's do it, you prepare all the raw materials you need for me, and then process them into parts according to my requirements, and I will assemble and debug them, I don't know when you need it?" ”

Lin Yuan thought for a while and said: "We are now in the process of building a railway from Beijing to Zhangjiakou, it turns out that there is a section of railway here, but the track spacing is relatively narrow, and the rails are too light. ”

Qin Peng nodded, Lin Yuan came out of him, what he didn't expect was that the laser wouldn't be useful for a long time.

As soon as Lin Yuan walked out of the R&D center, he received a message from Hou Zhengfeng: There is something wrong with the railway, you have to come back quickly to deal with it, as for what it is, we will talk about it when you return to Beijing.

Lin Yuan hurriedly returned to Beijing, Hou Zhengfeng was at the construction site of the railway, Lin Yuan came here to take a look, only a dozen Chinese migrant workers were dismantling the original railway on the huge site, and the American workers could not see a single shadow, and the 75 kilograms per meter of heavy steel rails transported from the northeast were lying alone on the track-laying car.

Lin Yuan hurriedly found Hou Zhengfeng and asked, "What's going on?" What about American workers? All on strike? ”

Hou Zhengfeng said: "They are all sick. ”

Lin Yuan was shocked when he heard the word "sick", he couldn't help but be afraid, in case of a large-scale epidemic of disease, maybe a lot of people would die, and there would be international disputes involved, so Lin Yuan asked, "What disease do they have?" ”

Hou Zhengfeng said: "It is said that it is a cold, and it will infect people. ”

Lin Yuan thought to himself: "Although the cold is a minor illness caused by a virus, but in this era when there are no antibacterial drugs, let alone antiviral drugs, if it really becomes a large-scale epidemic, there will be countless deaths and injuries, not to mention anything else, the Spanish flu during the First World War, the number of infected people exceeded 200 million, and the death toll exceeded 50 million." ”

"What's even more terrifying is that if these cold viruses come from the American continent, the Chinese do not have antibodies to deal with it, and the number of deaths will be higher, so we must quickly find a way." Lin Yuan thought of what he had told Chen Xin about the development of the pharmaceutical industry, but he didn't expect it to come in handy so soon.

Lin Yuan thought for a while and said, "I'll go to their shed first to see their situation, you are old and your immunity is weak, so don't go in." ”

Lin Yuan came to the construction site where the Americans lived, only to see that the Americans had built more than a dozen rooms in the open space, surrounded by dense wooden fences, and could not see the inside from the outside, and the door was guarded. ”

Although the worker's scolding voice was very small, Lin Yuan still heard it, and he didn't care, but said: "Don't get me wrong, I heard that there was influenza inside, I want to go in and take a look, and I will ask a doctor for you after seeing the situation." ”

The worker said in stiff Chinese, "It's none of your business!" ”

Lin Yuan listened to the worker's impatient tone and thought to himself, "Why are you still unhappy if I want to treat you?" It must be that he is not good at Chinese and does not understand what I mean. Lin Yuan then repeated his sentence in English again, but he didn't expect the worker to burst into flames when he heard it, and roared angrily: "It's none of your business, get out of here!" ”

Lin Yuan thought to himself: "No, there must be something wrong with this group of people, if it is really a cold and epidemic among them, how can they not let outsiders in for diagnosis and treatment?" I don't know what they are secretly planning inside? Lin Yuan smiled coldly when he thought of this, and said, "Do you know who I am?" You dare not let me in! ”

The worker smiled disdainfully: "I don't care who you are, even if the emperor comes, you can't go in, this is our American place." ”

Lin Yuan said sharply: "I am Lin Yuan, the governor of the three eastern provinces, if you don't get out of the way, don't blame me for being rude!" ”

The worker Ha Lu Ha Da Lu smiled and said in Chinese: "The chief pig of the three eastern provinces, run in with hooves." ”

Lin Yuan didn't bother to take care of him, he stepped inside, the worker saw Lin Yuan breaking hard, scolded angrily, stretched out his hand and pushed Lin Yuan, but before his hand touched Lin Yuan, he saw Lin Yuan's arm move, and then he felt that his hand was twisted by a huge force, and his arm involuntarily followed the strange force in a circle.

The arm turned to the limit and couldn't turn anymore, so he had to let the body follow the turn, so the big man turned around and fell to the ground with a "plop" driven by the strange force, but the strange force still didn't mean to stop, but at this time there was no place for the whole body to move anymore, so it became the arm to bear the strange force.

Dahan suddenly felt a sharp pain coming from his arm, and he hurriedly wailed, it turned out that the trick Lin Yuan used was the "twisting hand" in Tai Chi, Lin Yuan's reaction speed was much faster than ordinary people, so when he saw Dahan's hand stretched out to him, he shot out like lightning, grabbed Dahan's palm with both hands, and twisted it in one direction, Dahan couldn't resist it, so he could only kneel on the ground and howl miserably.

Lin Yuan saw the tragic situation of the big man, kicked him to the ground, kicked open the fence door and walked in, as soon as he entered the courtyard, the scene inside suddenly stunned him, it turned out that there were several large fires in the yard, meat was roasted on the fire, everyone played cards around the fire, and there were a bunch of beer bottles scattered on the side.

Lin Yuan suddenly understood that this group of people was completely pretending to be sick! Lin Yuan was just about to speak, when he saw everyone drop the cards, picked up the wine bottle next to him and stood up, at this moment, I don't know who Lu Dao was, scolded viciously, rounded his arm, and threw a wine bottle towards Lin Yuan.

The wine bottle was full of wine, one weighed five or six pounds, such a weight smashed on the body, people must not be able to bear it, everyone was waiting to see Lin Yuan's joke, but they were surprised to find that Lin Yuan looked at the flying wine bottle, did not dodge or dodge, his hand moved to his waist, and then there was a crisp sound of "pop", and the wine bottle had been shattered in the air!

Then I saw Lin Yuan holding a black and blue pistol in his hand, and the muzzle of the gun was coldly pointed at everyone.
