Standing in the Qiankun world, Yu Sanjin's forehead was covered with beads of sweat, and the feeling of being targeted by mysterious creatures was really terrifying, and it still made him palpitate.

Just now, as long as he escapes into the Qiankun world a little later, he will definitely be devoured by that mysterious creature and his bones will be gone.

What the hell is it? Like a dark ghost, invisible and silent, it makes his spirit tremble.

Hearing the movement, Hou Ye and Ram King Kong ran out of the cave, and behind them, there were several infant souls flying, which were the infant heavenly souls that came out of the Spirit Rhino Pill when they used the source refining technique.

"Boss, are you here?" Hou Ye shouted with a big grin, but there was some grief in his tone.

Ramming King Kong, then hummed and shouted, which means that Yu Sanjin has not come in for too long, and the meat stored in the Qiankun world has almost been eaten.

Those infant heavenly souls flew up and down around Yu Sanjin's side, looking extremely close.

Since participating in the Tianjiao War in Da Luo Zong, due to the shocking changes in Beiling City, the appearance of Yi Nu, the stationing of Shenluo City, and the integration of the Shenluo Realm, later, because of Ning Zijin's matter, it is necessary to go to the Floating Cloud Domain through Yudu, and too many things have happened in Yudu, until today, falling into the mysterious abyss, tossing and turning, nearly a year has passed.

During this period, due to no leisure, Yu Sanjin rarely entered the Qiankun world, and the last time he came in was when he was in the Shenluo realm, he sent food to Hou Ye and Tam King Kong, two foodies, and he still came and went in a hurry.

Now that I think about it, it is true that I haven't met Hou Ye and Ram King Kong for too long, so it's no wonder that these two foodies have some complaints.

He looked at Master Hou and found that this guy had grown a lot taller, and the most striking thing was that a handful of golden hair had grown in the middle of his forehead, which looked extremely extraordinary.

And the ramming of King Kong, which has already advanced to the early stage of the high-level demon beast, has shrunk its burly physique, and it seems to be more spiritual.

"Not bad! Not bad!" Yu Sanjin nodded and said, "In just a few months, both of you have made great progress!

"Boss, when will you let us out?" Hou Ye scratched the back of his head and shouted.

"I can't get out for the time being, your boss and I are trapped!" Yu Sanjin said.

"So, the boss won't be able to get out in a short time?" Hou Ye exclaimed excitedly.

Yu Sanjin nodded, the current situation is indeed like this, those mysterious creatures outside, if they keep guarding that door, they really can't get out.

"Then the boss will make us something to eat!" Hou Ye said with a greedy face, obviously, after being locked up in the Qiankun world for too long, its beak was about to fade out.

"How much food is there here?" asked Yu Sanjin.

"It's enough for the two of us to eat for a few months!" replied the Hou Ye.

Yu Sanjin relaxed a little, since he entered the Lingchi Realm, he has already opened the valley, as long as there is a place where there is the aura of heaven and earth, he can absorb it by himself to supplement the needs of the body, and there is no longer a need to replenish the body's energy by ingesting food like the Lingyun Realm.

But the current situation is very bad, because the dark abyss outside has no aura, even if you can go out, you can't replenish your vitality by absorbing the aura of heaven and earth, so you must replenish the energy of your body in time.

If you stay in the Qiankun world, it doesn't hurt in the short term, because there are some auras here, but the auras here are all retained from the original, and the total amount is also fixed.

If you don't open up a new activity area, the aura will be consumed sooner or later, and at that time, you will have to maintain your life by taking Bigu Dan or eating.

Therefore, the food storage in the Qiankun world is extremely important.

Of course, Yu Sanjin can also convert the true qi in his body into energy to sustain his life, but in doing so, he must take other pills or absorb the spiritual power in the spirit beads to replenish the true qi.

He was reluctant to do so until he had to.

The aura of heaven and earth is naturally generated, and it is the essence derived from the sun, moon and stars, the spiritual veins of heaven and earth, and the five elements of yin and yang, and it is difficult to replace it with other things.

Therefore, there is a difference between spiritual power and spiritual energy, spiritual power is more used to transform true qi or true element, so as to improve cultivation, and spiritual energy can not only be used to transform true qi or true element, but most importantly, it can also be used to maintain vitality.

For example, absorbing spiritual energy is like drinking water, absorbing spiritual energy is like breathing, drinking water cannot replace breathing, but breathing can take in a small amount of water, although it is not as direct as drinking water.

The key is that after the cultivation is improved, the potential of the body is infinitely developed, the speed of absorbing the spiritual energy of heaven and earth is accelerated, and the amount of vitality stored will also increase.

The energy transformed by true qi is a kind of virtual energy, which has no materiality, just like strength, it is not that if you have strength, you don't need to eat, on the contrary, you will definitely have no strength if you don't eat.

Therefore, true qi cannot replace the intake of food, let alone derive new vitality, that is to say, if you want to convert the true qi in the body into energy to maintain life, in fact, it is just drinking doves to quench thirst.

Because, the vitality in the human body is fixed, and the conversion of true qi into energy can only delay the speed of vitality consumption, and in doing so, sooner or later the balance of the body's storage of vitality will be broken, thereby harming the root and depleting longevity.

At the beginning, when Yu Sanjin broke into the Lingyun Zhen Realm, he experienced this kind of process, but at that time, he was in an unconscious state, which was actually very thrilling, and if he was not careful, he might run out of oil.

The reason why Bigu Dan can replace food is that it actually gathers a large amount of energy in it, so as to achieve the purpose of not eating in a short period of time, this energy is material, therefore, the most important refining material of Bigu Dan is the flesh and blood essence of demon beasts and nourishing spirit grass.

Other pills are not, more effective is to replenish spiritual power, refine spiritual power, dredge the meridians, remove hair and marrow, break through the barrier, break the bottleneck, improve perception, heal the wound and strengthen the body, etc., they also cannot replace the intake of food, even if it contains some material energy, it is also a negligible existence.

Of course, many pills have the effect of replenishing vitality, because the refined heavenly and earthly treasures are nourished by the spiritual energy of heaven and earth, but the amount is not much.

For example, some healing elixirs are effective for low-level monks, but not for high-level monks, because if high-level monks are injured, they need a large amount of vitality to make up for it, and the trace amount of vitality in the elixir will not work at all.

Therefore, whenever a high-level monk heals his wounds, he will often have to retreat for a hundred years, and the reason is to slowly absorb the spiritual energy of heaven and earth for a long time to make up for his vitality.

The elixirs or heavenly treasures that can replenish the vitality of high-level monks are all rare except for the list, which is why those pills and heavenly treasures that can replenish longevity are so precious.

Some people may ask, why don't you just refine the aura of heaven and earth into an elixir?

The idea is good, but in reality it is very difficult.

Because, the aura of heaven and earth is not air, which can be absorbed by monks, but it is difficult to collect and store, such as the essence of the leylines, the essence of the sun and the moon, the essence of the stars, the essence of the five elements, etc., these are all one of the spiritual qi of heaven and earth, which only exists in the underworld, how can it be refined into the elixir?

Therefore, the spiritual power condensed in the elixir and spirit beads cannot replace the spiritual energy of heaven and earth to maintain the vitality of the human body.

Where there is abundant aura, the reason why it can promote the speed of cultivation is because aura can be transformed into true qi or true yuan, and secondly, because aura can replenish vitality.

It is also for this reason that the major forces will compete for some blessed places with abundant spiritual energy to establish mountain gates.
