As night fell, the scattered crowd followed the marker to a clearing to converge.

Someone has already picked up a pile of firewood, but it is very humid and difficult to ignite without treatment. It takes a few days to dry naturally, but fortunately, there are a few people in the team who practice Yang True Qi and use their own True Qi to dry the firewood.

After a few rubs of the flint, the spark falls into the pyre, and the faint flame ignites and expands rapidly. The warm glow of the fire dispels the darkness and the chill of the night, and the burning pine gives off its own unique aroma.

On the fire were a few prey that had been hunted, mostly small animals such as rabbits and pheasants. It's not that they can't hit bigger ones, it's just that there's no need for this, just enough to eat. Larger prey can only be thrown away if it can't be eaten, and the bloody breath may attract other predators in the mountains and forests.

There was also a small pot in front of Cheng Kun, which was stewed with the poisonous snake he had caught during the day, and the snake gallbladder had been dug out and eaten by him.

The chicken and rabbit are grilled and sprinkled with a few grains of coarse salt, and they taste great. Cheng Kun's snake soup was also distributed to a few people around him, and he only drank a small bowl himself. The hot soup entered his stomach, and his somewhat tired body was revived.

After eating, everyone talked about the results of the day's exploration.

Because they were not familiar with the surrounding terrain, they didn't run too far. One of Peng Rou's scouts named Han Meng noticed something suspicious, but he wasn't sure if it was left by Dai Yue'er and her maid.

Aside from him, no one else made any notable discoveries.

In the end, Peng Rou decided to follow the path that Han Meng had walked today early tomorrow morning. She is the president's leader, and no one objected to it.

For the rest of the time, everyone briefly sketched the terrain they had walked on the ground, and after summarizing, it was a map of Broken Dragon Mountain.

Usually, everyone will not run to this ancient mountain, but this time I will take the opportunity to chase and kill Dai Yue'er to draw the map, if there is something to enter Broken Dragon Mountain in the future, it will be much more convenient.

Ancient maps were rather imrigorous, without a strict scale, and the hills and rivers were outlined in the form of stick figures. The topography alone makes it impossible to tell how long the river is or how high the hills are.

These people are basically old wars, and they all understand the importance of maps. It's not that they want to draw the map like this, it's just that no one tells them what the real map looks like.

Modern cartography was developed on the basis of mathematics, geology, geophysics and many other disciplines, and with the level of science and technology at that time, the Chu Dynasty might have reached such a height in a few hundred years.

Cheng Kun, who was accustomed to looking at modern maps, couldn't bear it anymore, so he stepped forward and briefly described the concept of scale and contour lines to General Peng.

After understanding the meaning of scale and contour lines, many people were amazed.

Someone praised it: "This is good, if the map has the scale mentioned by this Cheng Tun commander, it will be much easier to design the marching route and logistics supplies, and there is no need to set aside a lot of redundancy every time like now, not to mention wasting time, it is easy to delay the fighters." ”

Someone next to him chimed in: "That's true, this contour line is also very interesting, and the height of the terrain such as peaks and valleys can be displayed in this way, it's really a wonderful idea." It's just that I'm a little confused, how can I accurately get the difference in height between the various terrain and the sea level?"

The man stumbled a little when it came to "strange words" such as "sea level" and "altitude difference", but even though he had heard these words for the first time, the characteristics of the Chinese language allowed him to understand the meaning behind the words by words.

Cheng Kun was also a little dumbfounded when he faced this question, he accidentally said a little too much, of course, it is not so simple to measure altitude. In later generations, there was a special altitude measuring instrument, but in ancient times, he was not very clear about what to do.

After all, he was just a soldier who knew some kung fu in his previous life, and he was not a university professor, as long as he could read the map, who would care how it was made.

Cheng Kun looked up to the sky and said: "The altitude is just an idea of mine, based on the sea level, no matter how big the map is, there is no need to worry about the altitude error, but I haven't thought about what to do." ”

Everyone else expressed their understanding, and it was already very good for Cheng Kun to be able to put forward so many good suggestions. If he did come up with a method that worked, they would be more frightened than happy.

Peng Rou watched with a smile from the side, she was becoming more and more satisfied with her new subordinate. In martial arts, talent is not to say, and he also has his own set of affairs to deal with, so that the achievements of talents in the future will not be small.

After redrawing a map, the surrounding terrain was visible at a glance, which provided a lot of convenience for the next action.

Early the next morning, after eating, Peng Rou and Chu Liuyun walked towards the suspicious traces that Han Meng had said. Since it is suspected that Dai Yue'er may appear nearby, it is best not to divide the troops for the time being.

If you are alone, many people in the team are likely to be killed by her slap before they can give a warning after encountering Dai Yue'er.

The suspicious trace mentioned by Han Meng was nothing else, it was a pile of burned firewood. At this time, there are also people who cut wood and hunt in Broken Dragon Mountain, but it is really difficult to determine whether it was left by Dai Yue'er from this point.

It's just that this is the most likely direction found so far, and everyone is reluctant to let go, so everyone continues to move forward in this direction.

Cheng Kun walked at the back of the team and was always vigilant, but as he gradually deepened, his intuition also lost its effect.

It's not that he can't perceive anything, on the contrary, his intuition perceives too many possible dangers, and he doesn't know if there is an element of Dai Yue'er in this.

In the records of Taoism, the beginning of heaven and earth is a chaotic vitality, the so-called weather Hongmeng, the beginning of germination, then divide heaven and earth, establish the universe, enlighten yin and yang, distribute vitality, is pregnant and neutralized, is also a human being. *(Quoted from "The Chronicles of the Five Fortunes")

All things in heaven and earth, including human beings, are essentially a mass of vitality, which is the Taoist worldview. The people of this era believe in this, and the warrior can indeed feel the heaven and the earth after stepping through the entrance, and absorb the vitality to nourish himself, which proves this doctrine from the side.

Therefore, many martial artists who practice Taoist exercises will stay away from the world and return to the mountains and wilderness after breaking through the grandmaster, believing that the vitality here is richer and purer, which is more conducive to their next cultivation.

If this view is correct, then Broken Dragon Mountain is definitely a blessed land, and the deeper the mountain, the stronger the vitality. Such an environment is blessed with unique and inaccessible people, so many exotic beasts have been bred.

These beasts are different from ordinary beasts, they are more psychic, and their longevity is far beyond the imagination of ordinary people. Many alien beasts that have survived enough years can not even fall behind in the face of grandmaster-level masters.

But strangely enough, although these beasts are of different types, there is one thing that is surprisingly consistent, and that is the disgust for humans.

If they see a human in front of them, the mildest beasts will not hesitate to drive them away, and more will attack and kill them. No one knew the reason behind this, and as time went by, there were fewer and fewer people who dared to go deep into Broken Dragon Mountain.

Although Cheng Kun's current position is still a long way from the depths of the Broken Dragon Mountain where the alien beasts live, his intuition is very sharp, and he feels the malice of the alien beasts from a long distance.

This kind of sensitivity is a burden for him at the moment, it's bad to know nothing, and it's just as bad to know too much useless information, Cheng Kun is like this now.

His instincts, though sharp, were not as strong as they are now. It seems that this enhancement only started after he began to try to cultivate the "Heaven and Earth Method", but he didn't notice it.

Cultivating the eyes and ears through the heavens and the earth can greatly enhance people's eyes and hearing after cultivation, but if it is only so, it is not worthy of its name.

Cheng Kun once laughed at the predecessors who created this exercise when he jumped out of the hands of the Iron Bull instructor, but now, although the other party still hasn't gotten rid of the suspicion of bragging, this exercise is much more mysterious than he imagined before.

While cultivating the eyes and ears, this technique is also trying to cultivate the ethereal spirit through the tempering of illusions in the cultivation process, although Cheng Kun has already benefited from it before he has started.

He already had amazing intuition, and coupled with the fact that he was a human being in two lives, his spirit was much stronger than that of a normal person, so he discovered that the Heavenly and Earth Law had just a little insignificant effect.

Normally, it is impossible for a grandmaster to come into contact with the spirit before, they will only gradually accumulate true qi in the practice of meditation day after day, and then indirectly nourish the spirit.

After the grandmaster, only some people who are lucky enough and have high enough qualifications can touch the shadow of the spirit, which is also the only way to the great grandmaster.

But now the Tongtian and Earth Law is actually trying to make the martial artist start cultivating his spirit at the Tongmai stage, and it seems that it can really be done, but the cultivation is a little more difficult.

If this news is spread, it will definitely set off an uproar in the martial arts, which simply breaks the common sense of martial arts.

Cheng Kun dared to bet that the people in the Dingshan army must not have discovered the hidden mystery in the law of penetrating the heavens and the earth, otherwise, how could such a miraculous feat be regarded as a group of recruits to compete with the reward.

After realizing this, Cheng Kun decided to hide the news for the time being, he didn't know if the people who had practiced this exercise in the past had discovered this, but he had a hunch that if he said it, it would probably bring him a lot of trouble.

His wings are not plump now, and the most important thing at the moment is "obscene development", and it is better to have fewer unnecessary troubles.

Cheng Kun doesn't care about his intuition, since there is no way to know the source of the danger, it is useless to think more, it will only increase the burden on himself.
