With the External Core orb returned to its place, the spell in his hand was also coming to an end, and the magic array created by the Thick Earth City Fortification Technique gradually dissipated.
After the magic circle disappeared, a large nuclear power plant was thus completed.
It's quite different from existing nuclear power plants, and it seems to be missing a lot of things. But that's true, since Li Xingkong doesn't need it to generate electricity, and without water cooling and turbine motors, the entire nuclear power plant is much smaller.
Fallout protection measures were not implemented around the nuclear power plant, since this is the moon, which has no atmosphere.
There's plenty of Fallout in space, so a tiny bit from a nuclear power plant won't make a difference.
Besides, no one unrelated to this nuclear power plant can reach this location. After all, Li Xingkong specifically chose this place, and there are no gaps in the surrounding craters to enter or exit. The only way to get here is to send a spaceship from space.
But a normal person wouldn't come into such a crater.
Moreover, the Earthly Capital will implement corresponding management measures to ensure the safety of the nuclear power plant.
Everything is settled, just one last step remains.
Li Xingkong took out the remaining radioactive material from his Space Bag, then used his Divine Sense to control it and threw it into the corresponding location in the reactor.
Then Li Xingkong snapped his fingers, and the entire nuclear power plant began operation.
Even on the moon, in a vacuum, Li Xingkong could sense that a destructive energy was slowly gathering within the building before him.
As the reactor began to operate, Li Xingkong felt a warmth in his arms.
He picked up the External Core from his body, and sure enough, the immense heat was emanating from External Core.
Like a burst of energy, the heat radiated outwards for three or four feet before ceasing to expand.
Li Xingkong reached out and pinched the External Core. Then he felt a powerful heat energy begin to flow through his body, and the source of this heat energy was the small External Core in his hand.
He placed the External Core inside his clothing. The entire External Core continuously emitted energy, and Li Xingkong couldn't help but speed up the circulation of his Qi Refining Technique, absorbing all of this heat into his body.
With the addition of this external force, Li Xingkong's Magic Power circulated faster and faster. In just a few breaths, Li Xingkong felt that his Divine Sense had increased slightly.
Although the previous growth rate was not slow, it was only during periods of secluded cultivation. Now, Li Xingkong felt that his Divine Sense was constantly growing even when he wasn't cultivating.
It seemed that his External Core had worked, and Li Xingkong was delighted.
With this thing, Li Xingkong felt his cultivation speed had increased again.
Besides cultivation, this External Core also has many other effects.
The simplest way is to use it as a weapon. The large amount of heat it carries can be concentrated and exploded, and the damage it can cause is much greater than the self-destruction of the Zhang Family cultivators before.
You could say this thing is a small nuclear bomb; it's ready to use right away.
In addition, using External Core to construct external avatars or as ignition material for alchemy furnaces is also quite suitable.
After all, the heat and fire generated by nuclear power are based on the same principle as the sun, so it's not unreasonable to consider this a low-end version of the sun's real fire.
Using the true fire of the sun to refine pills would be quite remarkable in an ordinary cultivation civilization, but for Li Xingkong, it didn't have much of a special characteristic.
It's worth noting that Divine Land People have been using the sun to heat water for many years.
Even though it's far away, let's not worry about that, just ask if this is an application of the sun.
After putting away the External Core, Li Xingkong looked completely relaxed.
With this thing, his next seclusion could begin. However, before that, Li Xingkong still had some matters to attend to with Divine Land.
One reason is that there are more and more people who have reached the Late Qi Refining, and as time goes on, it is only a matter of time before they advance to Foundation Establishment. Li Xingkong needs to make a few Foundation Establishment Method for Divine Land. On the other hand, his seclusion this time may last longer, which makes it even more necessary to say goodbye to his family and friends.
After this period of seclusion, besides attempting to break through to the Golden Core, another crucial juncture is approaching.
That is the first of the many tribulations in cultivation: the Physical Body Tribulation.
As mentioned before, the sign that one has overcome the Physical Body Tribulation is that one can achieve immortality in terms of physical health.
Even though Li Xingkong can now abstain from food, as long as he is alive, he still needs to exchange some necessary substances with the world. Although he can maintain his bodily functions through metabolism, there will still be some loss in the body during the metabolic process.
While it's possible to replace one's entire body like on the Ship of Theseus, such immortality still relies on existing material resources.
Only after reaching the Golden Core can one truly overcome this first tribulation.
Upon reaching the Foundation Establishment stage, although one gains a certain ability to observe and manipulate the microscopic world, this ability is still limited. However, upon reaching the Golden Core Stage, as this ability deepens, cultivators can do something that was previously impossible: forcibly breaking chemical bonds.
This also means that cultivators who have reached the Golden Core stage can completely isolate themselves from the outside world and do not need to interact with it in any way.
Breathing oxygen turns into carbon dioxide, which doesn't need to be expelled. The carbon dioxide simply needs to be forcibly broken down and reassembled to form oxygen. From this point on, all the chemical reactions within the body can be forcibly reversed under the cultivator's powerful control.
At this point, with a pure and immaculate physical body, a cultivator can truly overcome the first tribulation on the path to immortality.
Even if one dies and one's spiritual path is extinguished, the physical body can remain in the world forever, and can even be used to make treasure ships to cross the void.
The saying goes, "Once you swallow a Golden Core pill, your fate is in your own hands, not in the hands of heaven." This is exactly the case.
Therefore, the Golden Core Stage is a very important watershed for cultivators. Before the Golden Core, one can live forever, but there is still a lifespan limit. After the Golden Core, one has a chance to live forever.
Therefore, this seclusion is very important for Li Xingkong, and the system's analogy of the Foundation Establishment Stage to middle school in the cultivation process is also very apt.
For ordinary people, the middle school entrance exam is their first chance to face their destiny, and the breakthrough to the Golden Core stage is the same for cultivators.
After considering his recent plans, Li Xingkong first took several Foundation Establishment Method from the system, recorded them into a Divine Sense structure, and imprinted them onto several pieces of material.
Not everyone can cultivate the " Heavenly Evolution Foundation Establishment Method." Li Xingkong before. Without a strong foundation and comprehension, it might be a problem to pass on this foundation Foundation Establishment Method.
Therefore, some low-level Foundation Establishment Method are also necessary, since these methods are intended for the general public, and the goal is to make them accessible to as many people as possible.
Li Xingkong placed several Foundation Establishment Method into his Space Bag. His current Space Bag beacon was still in a warehouse in the Earthly Capital, and using it to transport items was quite convenient.
Then Li Xingkong contacted Zhang Yumeng and told her about the cultivation method, asking her to go to the warehouse to receive the items.
After settling matters concerning this method, Li Xingkong informed his parents and then used magic to construct a small house next to the nuclear power plant, which he used as his secluded cultivation place.
Having set up the necessary protective formations to prevent disturbances, Li Xingkong didn't look back and slipped into his secluded cultivation room.
This time, he will not leave seclusion until he has reached the Foundation Establishment Perfection.
