Hao Zhi has always used 300 meters above the land as a critical indicator of the concentration of aura.

At this critical height, the aura is aggregated by tens of thousands of aura particles into a filamentous aura.

Therefore, this critical value, like the zero degree of ice turning into water, is of great significance.

At that time, he absorbed spiritual energy at a height of 500 meters at the top of the magic capital, and he could absorb a trace of spiritual energy in 40 minutes and 13 hours, increasing at a rate of half a thread per day.

Converted, at the height of 500 meters of spiritual energy concentration in the magic capital, he was able to absorb 36 threads of spiritual energy in 24 hours, and the concentration of spiritual energy at that time was increasing at the rate at which he could absorb a little more in 24 hours.

In other words, as long as it takes 36 days, the aura he can absorb in 24 hours can be doubled, becoming 72 threads.

This means that every 36 days, the concentration of aura in the air doubles.

Based on this calculation, now that 5 months have passed, and the number of days in the five months is removed to 36 days, it can easily be concluded that the concentration of Reiki has increased by more than 4.2 times.

As the concentration of aura increases, the height of the threshold will naturally decrease.

Originally, Hao Zhi didn't pay much attention to the drop in the height of the critical value, but when he visited the mountain today, he was interested in scanning the entire Bixia Mountain, and immediately found that most of the entire Bixia Mountain was above the critical value.

With the familiar Bixia Mountain as a reference, the drop in the critical height becomes particularly obvious.

Hao Zhi roughly measured that the critical height used to be 300 meters, but now it has dropped directly to about 100 meters.

Descending 200 meters in 5 months, at this rate, isn't it only 2 and a half months before the critical height of the aura can be lowered to the surface?

And now the critical height is only 100 meters, doesn't that mean that almost all the mountains on the surface have a filamentous aura?

No matter how short the mountain is, there will always be one hundred meters.

Even some buildings with forty or fifty floors can reach a critical height.

Realizing this problem, Hao Zhi couldn't care about chatting with Yu Yongjun anymore, and after he hurriedly said goodbye to Yu Yongjun, he immediately took out his mobile phone and dialed Su Tiancheng's phone.

"Have you ever measured the aura layer?" As soon as the phone called, Hao Zhi immediately asked Su Tiancheng.

"Measuring the aura layer?" Su Tiancheng replied with a lack of certainty: "As far as I know, there should be no one doing research in this area, and there are very few people who can sense the aura now, let alone measure the aura layer." ”

"Let me tell you a piece of news, the critical height of spiritual energy of 300 meters in the past has now been reduced to 100 meters, that is to say, as long as it exceeds a hundred meters of the mountain, it is possible to form spirit plants and spirit beasts. You should know what that means!"

"What? I'll report it right away. As soon as Su Tiancheng heard Hao Zhi's words, he immediately understood what he meant, and he was about to hang up the phone and report immediately.

"Wait a minute, I'll send you a document in a while, which contains a description of the realm I summarized, and you can submit it together. ”

"That's what kind of soul refining body you are talking about?"

"Yes, that's it, I only have one request, I hope that the upper echelons will release the content of this document to the whole society, and do not keep it secret. ”

"Okay, I'll tell you that. ”

The reason why Hao Zhi wanted to release the realm description he had summarized was entirely because the growth rate of the aura was too fast.

It can be expected that after 2 months, the critical height will reach the surface, and the animals and plants on land will enter a period of rapid evolution.

If human evolution slows down and loses to the animals in the evolutionary race, then the entire human race will fall to the bottom of the food chain, and the fate of human beings will definitely be very miserable.

Hao Zhi decided to release this document at this time, naturally to show everyone the way forward and give people a sense of urgency.

Whether it's inducement or intimidation,

Once people recognize the future situation, they will definitely not be satisfied with a thousand strands of aura and superpowers like now.

Hao Zhi thought very clearly, no matter how high his cultivation was, it could not compare to the evolution of the human race as a whole.

Civilization does not depend on one or two people for its survival.

When he returned home, Hao Zhi gave a detailed introduction to the first three realms of body refining and soul refining, and wrote down the amount of spiritual energy required for each stage, the ability that each realm could obtain, and the effect of spiritual energy liquid.

He compressed these together into a single file and sent it to Su Tiancheng.

The document is full of descriptive text introductions, and Hao Zhi is not stupid enough to make all the exercises public.

The exercises in his hands, except for the "Zhaowu Lei Benjing", which is Shirui's family tradition, other such as "Japanese-style Taijiquan" and the atlas of 9 spells are obtained elsewhere.

Hao Zhi believes that there are definitely more than these exercises and cheats left by the ancestors, and he is definitely not the only lucky person in the new world.

The last time I met Ruiguang real people on the Sanya yacht, isn't it the best example?

"Hey, apprentice, where are you?"

There was still a coconut for the koi in the ring, and Hao Zhi finished the paperwork, so he called the phone number left by the koi.

He wanted to find out where she was, so that he could give her the coconuts somewhere.

"Hello, I'm Koi's agent Xiao Xia, who are you?"

Belch~

"My name is Hao Zhi, I am her master, I have something to give her, you help me tell her, see when it is convenient for her, call me back." ”

"Okay, I'll tell you when the koi are free. ”

"You ......"

Toot ~ Toot ~ Toot ~

No way~

Before Hao Zhi finished speaking, the agent named Xiao Xia hung up the phone, and Hao Zhi wanted to ask about their location.

Since the koi was busy, Hao Zhi didn't think about it anymore, and waited patiently for her to call back.

After Hao Zhi went to his parents' house for dinner, he began his second patrol to kill ghosts.

After his sweep last night, the number of ghosts decreased sharply tonight, and in the first half of the night he flew down several times before he found dozens of ghosts,

Moreover, most of these dozens were transformed by people who had just died today, and the most one of them was less than a thousand spirits.

Hao Zhi decided to expand the scope of the search,

The two ghost kings who are expected to hide are probably not in the urban area.

Hao Zhi first searched the western part of Ninggang City, which is full of mountainous areas, and there are several small cemeteries in the mountains.

When he entered the mountain, he immediately found that there were a large number of spiritual plants in the mountain.

I'm really sluggish~

In fact, this can't blame Hao Zhi for being sluggish, he has just returned to China, and when he comes back, he is busy buying houses and houses, and he is busy collecting coconuts, all of which are ground activities.

It wasn't until today that I ran to Bixia Mountain in a hurry that I suddenly discovered the problem of the critical value.

The critical value has dropped, and the western mountainous area has become like Bixia Mountain, and it is normal for spiritual plants to grow.

Hao Zhi couldn't care about looking for the ghost king, so he immediately fell back to the ground and scanned these spirit plants in the mountain.
