Yuanye is naturally familiar with the setting of the secret realm. It is called "copy" when pronounced as "secret realm". With the experience of reading online literature, Japanese comics, American TV series and other entertainment and cultural works, he feels very calm when encountering anything.

In addition to the secret realm, there are also forbidden places, immortal caves, palaces, caves, blessed lands, small worlds, etc. In this world, people are very clear about these types.

In this world, the secret realm is undoubtedly the most dangerous. Most people will subconsciously frown when they hear these two words, instead of saying that when they hear a certain secret realm open, they will rush in, which is to seek death.

Perhaps only hired warriors like Wu Maqiu who licked blood from the knife can dare to enter the secret realm with a mortality rate of 60% or 70%. However, her characteristic of survival first in her bones can indeed greatly improve her survival rate.

Why is the secret realm so dangerous?

Because the laws are not perfect, the environment inside it is very harsh, and it is almost impossible for humans to live in it. There are only fierce and dull monsters, and the violent vitality inside is impossible to use even the human-shaped beasts like warriors.

It’s okay to be dangerous, but the most important thing is that exploring the secret realm is completely inconsistent with the gains you gain!

Who knows how much time has passed before the secret realm is opened? Some precious martial arts, elixirs, spiritual herbs, etc. have been destroyed. Who cares about the remaining residue?

Many people believe that the miniature worlds like the secret realm are basically those caves that powerful people actively abandon, or are places specifically used to cultivate specific monsters. Their value is that of the strange monsters inside.

The last time Wu Maqiu followed a certain innate warrior into the secret realm, in order to hunt an eighth-level monster called "Fei Lian". The other party's purpose was to hunt the horns on its head as a material for forging a sharp weapon. However, the group was lucky enough to encounter a ruin. The "Observation of Things" of the "Huangji Jingshi Shu" which is now part of the wilderness was obtained from it.

The secret realm is not popular, but those immortal caves, palaces, and caves are popular. Their owners may have fallen due to accidents, so there are still a large number of precious items in it. Even some restrictions are very dangerous, but this danger is truly proportional to the harvest!

Unfortunately, at least you have to become a master of martial arts to get a small share of the pie. Because of these opportunities, even the Taoists in the God Refining Realm who are transcendent and beyond the world are pursuing...

Not to mention the small world, it is almost completely controlled by the big families. After all, humans can survive in the small world, and they can also allow their descendants to enter the small world to experience. Often, ten years have passed in the small world, and this world has only been a year. If it weren't for the small world that had the limitation of cultivation, I'm afraid that those martial arts masters would not be able to help stay in there to practice!

However, the cultivation level improved in the small world will be a little further after returning to this world, because the laws of the small world are not perfect compared to this world.

Therefore, the greatest value of the small world is to make people more mature in their minds, and it is said that it will be of great help to break through to the realm of God Refining in the future.

Although Yuanye became interested in the place called "Hanhai Secret Realm" because of the "Huangji Jingshi Shu", he has no intention of exploring it at all, especially when he knows that the secret realm is very dangerous, even if he wants to go, he has to be prepared safely.

At this time, all the warriors were about to say goodbye to Yuanye, but Yuanye smiled and said to these people that he wanted to hire everyone present and ask them to cooperate.

If Yuanye hadn't just shown his very "Holy Mother" side, these warriors would have thought he was going to kill someone to silence him. After all, Yuanye was wearing a human skin mask and clearly didn't want others to know his true identity, but now his identity has been exposed...

Many powerful warriors who are cruel and ruthless will deal with such things - only dead people will not leak secrets.

Of course, Yuanye could not be so crazy. In his opinion, this was meaningless. He just asked these warriors to cooperate with him to do some research.

At this time, the group finally arrived at Sunset County City safely. Yuanye was about to practice one of the "Onlines of Observing Things" in the "Huangji Jingshi Book". With a super brain, he was always very relaxed and quick when practicing this exercise!

"Huh... it's finally completed. Let me see how effective this technique is." Yuan Ye thought, while taking out the photo stone he had obtained before and using it for a small experiment.

He inputs energy until he goes deeper, wrapping up the entire photo stone. After a while, he is surprised to find that this technique can indeed analyze the composition of the photo stone!

Although he failed to fully analyze it, he did understand something initially. The wonderful material in the photo stone itself has the functions of storing images, sounds and playback, which opened his eyes and gave him a lot of strange ideas.

"It's a pity that the 'Online of the Viewing Things' in the "Huangji Jingshi Book" I practiced is not complete. If it is complete, then we can analyze it more deeply and understand its essence. Even if it is artificially synthesized photo stone, it will not be impossible! Industrial production is the king!" Yuanye thought secretly.

The greatest benefit of this "On the Insider of Things" to the wilderness is that it no longer needs to explore things through slices and dissections. Just input vital energy to roughly analyze what the composition of the matter is, which is enough for the time being.

The composition of matter in this world is indeed not a molecule or an atom!

This discovery made Yuanye both distressed and excited, but with a super brain, he summed up the most basic theorems very quickly. Then other theorems and laws need to be deduced based on these most basic theorems...

Now he has the field of "On the Inside of Things". At the level of insight into matter, it is probably like in the previous world where he could observe changes in molecular-level things, which means that he can deduce chemical equations, which are chemical equations that conform to the laws of this world.

In this way, he can finally start to study what kind of operation mechanism this spiritual marrow assists warriors...

It took him a whole month, with the help of sufficient experimental materials and the "On the Inside of Things" technique, he finally completely studied the operation mechanism of the spiritual marrow from the fourth level of the body-building realm to the sixth level!

Next he will make an item named "Acquired Spiritual Liquid" to help him advance directly to the sixth level of the Body Forging Realm!

In this way, he would not have to use only a small amount of vital energy stored in his body in his flesh and blood, because at the sixth level of the body-building realm, he could absorb a large amount of vital energy from the tendons and veins in his body, and he could also have a "vital energy yarn coat" on his skin, and he could "release vital energy"!

This will naturally give his strength a qualitative leap!

Others are upgrading from level to level, but they are directly upgrade from level to level to level. If other warriors know about this, they will definitely be shocked!

However, this is the power of science!
