Although they encountered many problems in the process of building controllable nuclear fusion, such as the power of the laser is not large enough, with the participation of Wang Bin, he purchased a lot of technologies from the science and technology mall. Finally, they overcame these difficulties one by one.


    At this time, the construction of the nuclear fusion reactor of Tiangong technology has finally entered the final stage. However, at this time, they have encountered difficulties, that is, the binding force of the magnetic restraint device is still not enough. If the temperature reaches hundreds of millions of degrees, it will cause great pressure on the shell of the magnetic restraint device and greatly reduce its service life.


    For example, according to the design data, the operation life of this nuclear fusion reactor is 30 years, but because the magnetic confinement technology is not in place, the operation life of the experimental reactor finally built is only five years.


    Therefore, this is absolutely unacceptable for the high-energy physics laboratory of Tiangong technology and Wang Bin and others. Therefore, Wang Bin came to the science and technology mall again, purchased the corresponding magnetic confinement technology, and carried out a series of upgrades for the magnetic confinement technology of similar nuclear fusion reactors that have been built. Make it meet the requirements of design data.


    Fortunately, their high-temperature superconducting material technology of Tiangong technology still meets the requirements of purchasing technology. Otherwise, Wang Bin must buy new high-temperature superconducting material technology in the mall, so he will have to pay a high price.


    After all, the high-temperature superconducting material technology mastered by Tiangong technology has actually reached the limit of this civilization, that is, the limit of class zero civilization.


    Therefore, we also want a higher level of superconducting material technology, that is, the superconducting material technology of almost first-class civilization. Even if there is such technology in the mall, its price is very expensive, which can almost ruin Wang Bin''s family.


    In fact, just for this period of time, in order to reduce the experimental nuclear fusion reactor, Wang Bin has spent a huge amount of energy money, which has almost drained all the energy money he has managed to save.


    Wang Bin and the technicians of the high energy physics laboratory carefully assembled the equipment of the nuclear fusion reactor without any carelessness. After completing the assembly of each part, Wang Bin and others had to go through more than ten or even dozens of inspections and confirm that there were no problems before the assembly of the next part.


    When Wang Bin and his colleagues accurately installed the last component on the reactor, Wang Bin and the researchers and technicians in the high energy physics laboratory were greatly relieved.


    However, at this time, Wang Bin and others were not excited with the completion of the assembly of the reaction device of the controllable nuclear fusion reactor.


    Because Wang Bin and the technicians and researchers in the laboratory are very clear that although the reactor has been assembled, no one can confirm whether the reactor can operate normally.


    After all, this is the first nuclear fusion reactor designed by Tiangong technology. No one can confirm whether the reactor can operate, how long it can operate, whether it meets the design standards, and so on.


    "Mr. Wang! We have finally assembled the reactor. Let''s eat first! After all, we spent a whole day for the last part of the reactor, and everyone hasn''t eaten yet." when the assembly and inspection were completed, the head of the laboratory, Mr. Jin, handed over some water and some food, He said to Wang Bin.


    After listening, Wang Bin nodded and got water and food from old Jin. After all, he was also very tired at this time. After all, the last module of the reaction device of the controllable nuclear fusion reactor was still very heavy, and in order to install accurately, they had to adjust it manually after the module was installed, which was not easy.


    So Wang Bin took the food and water from old Jin and ate it. At the same time, other people in the laboratory, like Wang Bin and old Jin, were struggling.


    However, during the meal, Wang Bin, Jin Lao and others quietly looked at the reaction device, with some hesitation and expectation. At the same time, they were also praying that the reaction device could operate normally.


    "Jin Lao! I don''t know when we plan to ignite?" Wang Bin asked Jin Lao.


    Although Wang Bin is the boss of Tiangong technology, Wang Bin generally does not intervene in various projects in various laboratories. It is basically decided by the person in charge of each laboratory. For example, when the reactor ignites this time is decided by Jin Lao, the person in charge of the high energy physics laboratory.


    After listening to Wang Bin''s words, Mr. Jin thought for a moment and said, "I think we will start the ignition in three days! In these three days, we will make a final inspection of the reaction device to see if there are any problems. If not, we will conduct the first ignition test in three days!"


    And Wang Bin also nodded and agreed with Jin Lao''s idea.


    In fact, like many people in the laboratory, Wang Bin wants to ignite it tomorrow and want to see the operation of the nuclear fusion reactor as soon as possible. However, for the sake of safety, he still thoroughly inspected it and confirmed that there is no problem. After ignition, he tries his best to ensure the smooth ignition. After all, everyone has paid too much effort for it.


    After eating, Wang Bin and Jin Lao returned to their residence in the industrial zone, took a good bath, and then had a good rest all night.


    In the following three days, Wang Bin, Jin Lao and others conducted a series of inspections on the reactor and made some modifications to some of the details found. Finally, after there were no problems, they decided to ignite.


    Early in the morning of the fourth day, Wang Bin woke up in the dazzling sun. After a hasty breakfast, he couldn''t wait to come to the controllable nuclear fusion experimental reactor in the high energy physics laboratory.


    However, when Wang Bin arrived at the scene, many people had already been here by the controllable nuclear fusion reactor.


    This includes the R & D and technical personnel of laboratories such as Jin Lao. In addition, there are Qin Lao and Qiu Zong, who represent the official. After all, as official personnel, Qin Lao and Qiu Zong naturally know the significance of controllable nuclear fusion technology more than anyone.


    It is precisely because of this that before, they approved it for the first time and invested a lot of manpower and material resources after Wang Bin and Tiangong technology submitted to establish a controllable nuclear fusion anti experimental reactor.


    Therefore, the reactor can be built in such a short time, which is inseparable from the official investment. Therefore, Wang Bin called old Qin and others as soon as the reactor construction was completed, and informed them of the ignition time.


    This is also the reason why old Qin and others will come so early today.
