Because when he handed over the Superman Soldier Serum to Liu Nan, Tony told Liu Nan about the side effects of the Superman Soldier Serum, although the Superman Soldier Serum can strengthen the human body, but it will make the human body dependent, that is to say, if you want to improve your strength, you must inject the Superman Soldier Serum again, although Liu Nan is very confident in kung fu, but the human body is too mysterious, Liu Nan still does not plan to take this risk.

The second is that the superhuman soldier serum will change some functions of the human body, such as fertility, which will reduce human fertility, which is why Frank gave his son a bodyguard, all-weather protection, and finally gave birth to a son, whether he can give birth in the future is not necessarily, what to do if he does not protect it, in contrast, Jin and Ke are much unlucky, there was a son before the injection of superhuman soldier serum, but he died, and he was injected with serum for revenge, but he has no children, and a foundation may collapse after his death.

Liu Nan will not ruin the future of Peter, David and Mindy for the sake of rapid improvement in a short period of time, in Liu Nan's opinion, Peter and they are all higher than their own qualifications, if there is no plane exchange system, it will not take two years, Peter They will be able to surpass themselves, Peter will not even use two years, with the Spider-Man bloodline, he will definitely be able to surpass himself in a short period of time without exchanging the small universe, this is the difference between genius and mediocrity.

For the Superman Soldier Serum, Liu Nan also has an arrangement, first of all, he must recover a few, otherwise how can he enhance it, and then the rest will be slowly injected into Damon and Frank to strengthen the two minimum combat power.

The way home is not so many twists and turns, all the way to the east, take the most famous Route 66, which is called the "Mother Road" by Americans, which traverses the east and west of the United States, and most Americans who want to go on a road trip will choose this road, and some people even consider it a tradition to travel on Route 66.

Because Highway 66 is very prosperous, there are many towns on both sides of the road, David widens his eyes every time he goes to a place, or eavesdrops on other people's speeches, to see if there is anything abnormal, can he find another murderer, the result is that David is very disappointed, on both sides of this kind of highway with a huge flow of people, how can there be a murderous maniac, to ensure that there are people missing on the first day, the next day there will be police to investigate, dare to have a dozen or twenty people disappear, there will be an army to search for the carpet.

In David's disappointment, everyone returned to New York, returned to the familiar city, breathed familiar air, the trip took more than a month, most of them were on the way to Los Angeles, and then stayed in Los Angeles for a few days, and it only took four or five days when they came back, it was really a bit of a tiger and a snake's tail, but Liu Nan was very satisfied, the two purposes of going to Los Angeles this time were achieved, befriending Tony Stark, getting the Superman Soldier Serum, and doing it quite perfectly, as for the issue of the shares of the new company, Liu Nan has never paid attention to it, it's a big deal to exchange for a prescription and exchange for some shares.

When I returned to Los Angeles, the first thing I did was to go back to my house to find my mother, Peter and David were half-grown children after all, and they missed their families very much when they went out alone for the first time, and Liu Nan was also very dependent on John and Lina since he let go of his heart, and he missed them very much after traveling for so long this time.

When he got home, he saw that Lina had prepared a large table of food to welcome him back, and John also put off the after-work entertainment and returned home early.

When Liu Nan called back and asked Lina to help him sign the contract, John's jaw was about to fall off, he didn't expect his son to start a company in partnership with someone silently, the partner was still the famous Stark Group President Tony Stark, and later heard his wife come back and talk about Liu Nan's shares and company funds, John couldn't help but smack his tongue, this kid has become the richest man in the family with just one company's shares, and he really underestimated Liu Nan before, so this time Liu Nan came back, he deliberately waited for Liu Nan at home, I want to "interrogate and interrogate" this son well.

For John's "interrogation", Liu Nan has already made an excuse, anyway, John and Lina knew that they had been practicing martial arts since they were children, so they said that they had found a prescription in the ancient books they bought from Chinatown, and then tried to buy some important tests and found that it was very effective, so they took the opportunity to go to Los Angeles to find Tony Stark to cooperate, but they didn't expect it to be really successful.

Liu Nan's rhetoric, John and Lina both believe unconditionally, they believe in their son, plus Liu Nan has shown extraordinary since childhood, this kind of thing may be suspicious in others, but in Liu Nan, it is normal, Lina can loudly announce that her son is a genius.

Anyway, Liu Nan has already taken the first step in society, John excitedly poured Liu Nan a glass of wine, which caused Lina's white eyes, but it was limited to white eyes, today is so happy, don't care about the rest, Lina is a lawyer, and she is still very sensitive to those things that violate the law, but today is to welcome Liu Nan back, so let's put the law aside.

John and Liu Nan were both drunk that night, and then they both went back to the room early to sleep, leaving a Lina to clean up the mess, and they used to work together as a family after dinner, so Lina made up her mind that after John woke up tomorrow, she must teach John a lesson, as for her baby son Liu Nan, it was all John's fault, Liu Nan was right.

The next day, Liu Nan got up energetically, there was no way to be in good health, that bit of alcohol, it was easy to decompose it all, and there was no sequelae.

John and Lina both went to work, and Liu Nan was left alone at home, Liu Nan also took out the refrigerator, first exchanged a few bottles of serum into the system, and replenished the exchange point that was close to drying up, after exchanging a few, there was no way to squeeze the exchange point from the serum, looking at the remaining more than ten serums, Liu Nan closed the refrigerator again, and then took out the phone and called Damon, asking them to meet in the abandoned factory.

I really don't know how the basement decoration is, during this time, Liu Nan handed over the basement decoration work to two people in order to let Damon and Frank have something to do, so as not to get bored and make trouble outside.

Coming to the abandoned factory, Liu Nan found the entrance to the basement and found that it had been hidden by Damon and Frank, and there were all kinds of miscellaneous items around it, if he didn't know that there was a basement entrance here, no one would be interested in coming here.
