After John and Lina came back, Liu Nan would chat with them every day, and Liu Nan also directly rented a medical machine with the exchange point to check the body of John and Lina, and completely treated and recovered the hidden diseases and some physical wear and tear on John and Lina's body, John and Lina suddenly felt that their bodies were rejuvenated, although they were not as young as those young people, but they were also in the prime of life, and all the backache and leg pain disappeared, which made John and Lina very happy, they could age healthily, and then die peacefully, This is something that many people dream of.

Of course, Liu Nan will not be missing Tony and Pepper, although they use the spring of immortality, it does not mean that they will not get sick, use a medical machine to treat hidden diseases, and avoid the troubles of illness.

Like last time, Tony couldn't walk away when he saw the medical machine, and he pulled Banner and knocked on the medical machine, and wanted to dismantle the medical machine, if it wasn't for Liu Nan staring at him, Tony would have gone overboard, Liu Nan would have imprisoned him with his mental power, I'm afraid Tony would really dismantle the medical machine.

Banner was very curious about the rays used by the medical machine, which was even more magical than the rays on the Nova Legion spaceship, and could integrate multiple functions of examination, treatment, and object transfer, which was more advanced than the cradle of life invented by him and Dr. Helen, which could only print epidermal tissue, but the medical machine could actually treat tissues under the skin.

"See, Banner, Liu Nan is so stingy that he won't even let him study it."

Tony, who was restrained by Liu Nan with telekinesis and brought out of the basement, was full of resentment, and then said to Banner.

Banner just smiled awkwardly, though he also wanted to study the machine. But he didn't have the thick skin of Tony, but he wasn't able to study it. Still makes Banner a little sorry.

"Tony, don't be greedy enough to swallow elephants. You've got so much to study, what do you have to do with this medical machine? ”

Liu Nan said helplessly, if this thing is his own, Tony dismantles it, Liu Nan will not say anything, but it is really rented from the plane exchange system, if it is broken, I am afraid it will not be rented, but exchanged.

"Liu Nan. Your friend won't be so stingy, since he can make one, he can make a second one, what if he gives it to you, and besides, he has a spaceship, and he can still look at this little machine? ”

Tony said that what Liu Nan told him was that the medical machine was borrowed from a friend, which made Tony very unhappy with Liu Nan's friend. How can you be so stingy, and how can you be called a friend if you are so stingy?

"Actually, it's not a friend, it's just a partner with an interest relationship, and I pay the price. Get something from him, and if you tear it down, the price you pay is not the price you pay for renting it. It's the price of the purchase, you get the idea? The spark of the Battle of Los Angeles in the first place. It was snatched away by me, and the fire is a kind of price. There are many, many more, or where can I get such a high-level machine, where can I get a spaceship, I know why I don't let you study it, because it's not my thing at all. ”

Liu Nan said helplessly, revealing a little bit to Tony.

"No wonder, your strength is also obtained at a price, right?"

After listening to Liu Nan's explanation, Tony also understood more or less that everything about Liu Nan did not come out of thin air, but could only be obtained at a price.

"That's right, so sometimes don't think that I'm very easy to become stronger, there is a price to pay, this price is definitely not simple money, money on the earth is simply worthless waste paper."

Liu Nan didn't hide anything, and answered Tony honestly.

"Okay, I won't study it, I said you're not so stingy, it seems that after giving us treatment, this machine will be returned."

After Tony knew the reason, he no longer worried about the medical machine, so as not to embarrass Liu Nan, the fire that can give birth to the Transformers is a kind of price, and Liu Nan has really paid a lot.

"That's right, our demand for this kind of machine is basically equal to nothing, so it's not worth spending too much money to get a machine to put here, unless you are sick, I will rent it again, but I don't think you can have two disasters in three days, so it may be used once every long time in the future, so the price paid is much smaller."

Liu Nan's body is all strong, there will be no disease at all, even if there is an injury, you can use the fairy bean to recover instantly, if you rely on the medical machine, it will be very slow for them, in case you are still fighting, the enemy will not give you time for you to treat, so the immortal bean that recovers the injury instantly will be Liu Nan's best choice.

"You are really realistic, if this kind of machine is successfully developed, do you know how much pain in the world can be alleviated."

Tony said to Liu Nan that if the medical machine can be mass-produced, all human beings will be able to get rid of the plague of disease, which is a great merit.

"Do you know how many people in the world are going to lose their jobs?"

Liu Nan also asked rhetorically, although it can keep diseases away from human beings, but all the pharmaceutical factories and scientific research centers in the world, including those who study medicine and pharmacy, will face unemployment, and when they are displaced into the world, I am afraid that there will be more troubles, and nothing can be just looked at.

Tony was speechless in an instant, indeed, he didn't think of this question just now, Tony himself is a businessman, and he also knows that if one thing replaces another, the person who makes another thing will be unemployed, just like his own energy building, but let several power generation companies go bankrupt, fortunately, Tony has not yet promoted new energy in the United States, otherwise a large number of unemployed people will pour into society, and the instability will cause greater trouble, so everything must have a process.

"Indeed, it is better to let the society develop slowly, and slowly eliminate those outdated things, so that the society can absorb those who are unemployed, if the one-time destruction is too great, I am afraid that the society will fall into turmoil."

Banner also agrees with Liu Nan's approach, if one enterprise closes down, it can still allow the society to slowly absorb the unemployed, but if all of them suddenly go bankrupt, then the society will not be able to accommodate so many idle people at once, and at that time, these people will have to do something bad in order to live, and the society will be in turmoil all of a sudden, and the crime will increase and the trouble will be greater.
