The book "Derivation of Heavenly Gong" contains many basic spiritual techniques, including the method of observing qi. It's a pity that Chen Feng didn't even practice the "Spirit Control Decision" well, and now he can't cultivate the method of observing qi.

Chen Feng stood in the back row of the formation of the 12th reserve team, strictly guarding, although he didn't know the basic spiritual skill of the method of observing qi, but he didn't have the heart to explain anything to his teammates in the 12th reserve team, anyway, he couldn't explain it clearly now, and there was no need to say too much in wartime.

Dark clouds obscured the moon, the vision was very dark, and people standing on the high wall of the defensive line could not see the situation at the root of the wall with the naked eye, but if the cultivator activated the method of observing qi, he could observe the breath fluctuations in the beast herd, and ordinary cultivators in the foundation building realm could see the breath fluctuations within 150 meters.

The method of contemplating qi is to condense one's own aura on the eyes, so that one can see the aura that cannot be seen with the naked eye, such as the demonic aura emitted by demon beasts, the aura condensed by the cultivator on the surface of the body, and the blood qi emitted by various living beings through the body,......

Like a beginner-level demon beast, the demonic aura on their bodies is strong, even if they hide in the beast group, they are as conspicuous as the fire in the night, after all, ordinary beasts have no demonic energy.

Although a practitioner can see all kinds of breaths in nature after activating the method of contemplating qi, the method of contemplating qi is not omnipotent, because when activating the method of contemplating qi, he can only see the breath that exists in the air, and the breath inside the object cannot be seen.

Just like human cultivators, they usually restrain their own breath, and even if they activate the method of contemplating qi, they can't see any difference between cultivators and ordinary people from their appearance.

The same is true for demon beasts that have evolved to the middle level, it is difficult to find them with the method of observing qi, they have opened their spiritual intelligence, and most of them know how to restrain their own demon qi, because in this state, the energy consumption of the body is relatively small, which will be more conducive to their own growth and evolution.

Like tonight, the dark clouds covered the moon and the vision was dark, and the rest of the 12th Reserve Team actually had no way to observe those mid-level demon beasts, however, none of them told Chen Feng about this situation, because they were all experienced in combat, so it was naturally impossible for Chen Feng, a fledgling, to move forward.

Except for Chen Feng, the rest of the 12th Reserve Team were all old men who were mixed in the realm of Baiyun City, so naturally they couldn't let a fledgling like Chen Feng look small!

......

Finally, a heavy rainstorm fell on the line of Luoyue Pass, and the pouring rain fell down, and the people on the high wall of the defense line were all drenched, but it did not bring them too much negative impact.

The people on the high walls of the defense line were all cultivators, and the cultivators' blood and qi were strong and their physical fitness was excellent, even if the rain slipped through their eyes, it couldn't make them blink their eyelids more.

On the other hand, the tide of beasts that covered the earth outside the high walls of the defense line had a bad effect, and in the crowded and chaotic beast herd, it was already difficult to breathe, and now the pouring rain was falling, and even a breath of air had water vapor mixed in, making the chaotic beast herd even more frightened.

The torrential rain continued to rain incessantly, and the ground became wet, and outside the high walls of the defensive line, the land that had been trampled by the beast tide became slippery, making it difficult for the giant beasts to walk.

The heavy rain made the soil under the feet of the beast tide muddy and slippery, which greatly hindered the progress of the beast tide, but in contrast, the side of the Daluo Kingdom was able to buy a little more precious time.

It takes a lot of time for the beast tide to migrate, especially the beast tide that is rare in a century. With so many different beasts gathered together, regardless of the tail, the beasts behind don't know how much distance they still have to walk to reach the first line of the Falling Moon Pass, if you look at the current situation, it is impossible to do it without a month or two.

There was nothing to do all night, and the cultivators who stuck to the high wall of the defense line were all poured by the heavy rain for a night, and none of the clothes on their bodies were dry, as if they had soaked in the pool all night.

The sky was lit up, but the sun did not come out, the dark clouds still covered the sky, the heavy rain did not weaken for half a minute, and the people on the high walls of the defense line were waiting for them, and they did not relax for more than half of the time.

At this time, the beasts crowded under the high wall raised their heads high, trying to breathe every breath of air, just to survive.

Chen Feng looked at the beasts struggling in front of the door of death under the high wall, and couldn't help but feel a little touched, at this moment, these beasts living at the bottom of the food chain in front of him were so difficult to even breathe a breath of air.

Maybe it's the heavy rain that weakened the beast's beast nature, and after a day, no demon beast climbed the high wall, and the 12th reserve team didn't harvest the spoils, and the atmosphere was a little gloomy, I don't know if it was because of the lack of harvest, or because it was affected by the heavy rain.

Chen Feng and the others were replaced again, returned to the garrison camp to repair, and the 12th reserve team changed into clean clothes, sat around the brazier in the house to roast the fire, and then ate food and drank strong wine to expel the cold in the body.

After everyone had eaten and drunk enough, they dispersed to rest, but Chen Feng did not leave the brazier, he took out the "Derivation Heavenly Gong", and then began to look at it seriously.

Wang Mang saw that Chen Feng was reading, so he was a little curious why Chen Feng didn't go to rest, Wang Mang knew that his team members had just gotten off the high wall, and now they should go to rest and rest well, and relax the tense nerves in their bodies in time, so as not to be affected by the pressure brought by the beast tide.

"Chen Feng, why don't you go to rest? The beast tide can't pass in a day or two, everyone has to take care of their spirits in order to win this battle!" Wang Mang sat down next to Chen Feng and asked out loud.

"Team Wang, I'm not sleepy yet, I'll read the book for a while, don't worry!" Chen Feng didn't squint, and replied while looking at the book.

"The light at night is not good, don't look bad at your eyes, won't you have time to see it in the future?" Wang Mang kindly reminded, and also encouraged Chen Feng to survive this beast tide.

"It's okay, I'll just watch it for a while!" Chen Feng said while looking at the book, like a student who studies hard in the school.

"What kind of book are you reading, so dedicated? This is "Derivation Heavenly Gong", I'll go, no wonder you don't know basic spiritual skills, it turns out that you haven't even memorized the enlightenment exercises of cultivators, you can really do it!" Wang Mang said with some disbelief.

Wang Mang only needed to take a glance and know that Chen Feng was holding the "Derivation Heavenly Gong" in his hand, because he was so familiar with this cultivator's enlightenment exercise that he couldn't be more familiar with it.

Wang Mang asked and answered himself, but Chen Feng did not speak, nor did he make any expressions, still looking at the book without squinting, not affected by the outside world.

"I'm a little sleepy, go to bed first, and you can rest yourself. Wang Mang saw that Chen Feng was reading intently, so he didn't bother anymore and left.
