Katu

During these thirty days, they killed hundreds of wild animals. Among them, there were more than twenty Shadow Fronts, and the fifteenth-ranked Black Nether Python and the fourteenth-ranked Bone-spurred Rhinoceros were both killed by their hands. As for other unknown creatures, there are more.

Thirty days is not a long time, but for the two people who have experienced bloody killings, it seems like a world away. Their strength is much stronger than before, especially Chen Mu, who has improved more rapidly in all aspects. In the Federation, there were not many battles that required his personal participation. In Baiyuan, every day is a high-intensity battle, with only the most naked killing and life and death.

After thirty days of training, he seemed to be a completely different person, reborn.

"I don't have much energy left." Chen Mu frowned. The constant fighting these days consumes a lot of energy cards. Fortunately, he is used to having a lot of energy cards, otherwise, he wouldn't be able to survive now. If the energy cards are exhausted, his combat effectiveness will drop sharply. His accomplishments in card-free flow are just average when dealing with ordinary card cultivators, but they are far behind when dealing with these ferocious beasts.

The movement of the devil woman's hand stagnated, then returned to normal: "What should we do?"

Chen Mu, who had a headache, took out all the things in his pocket. [Weak Water] Pens, various cards, money cards, etc., and a few small pieces of mud scattered among them. Money cards are worthless here. As for other cards, if there are no energy cards, they are just a pile of waste paper.

His eyes fell on those small black lumps of mud, and he was immediately overjoyed. How could he forget these little things?

Picking up a small lump of mud, he carefully pinched open the outer layer of black mud. A strong wave of energy impacted Chen Mu's world of perception.

Strong energy fluctuations are coming!

Chen Mu looked at these sapphire-like crystals with surprise and joy. His knowledge now is much better than before. Although he still doesn't know what these sapphire-like crystals are, he can roughly judge their properties. This is a crystal with a very high energy content. The energy density it contains far exceeds other energy-rich ores that Chen Mu has seen. For example, the more common moon stone used to make energy cards contains less than a fraction of its energy.

But despite this, he still faced the dilemma of insufficient materials. First, he needs blank cards. The key is that tanning blank cards is also a technology and requires many processes, which is obviously something he cannot complete now. Secondly, he needs a lot of auxiliary materials to process this unknown energy crystal.

Fortunately, Chen Mu is not a rigid person and knows how to adapt to local conditions. He had never thrown away the energy cards he had used up before. Now he only needed to clean and process them. And there were many cards in his card bag that he didn't need. These cards were discarded and reused by him, and they were all freshly processed.

As for the problem of other materials, he had no choice but to bite the bullet and solve it. For this reason, he had to re-search the area where he had been active for thirty days. He would check every living thing and every ore here. Without any testing equipment, no other processing tools, and no valid cards, he could only rely on the most primitive means - his perception!

He used his senses to scan any material he had not seen before, hoping to judge their performance from their microstructure.

What Chen Mu didn't know was that no one had ever used perception in this way. And if Caesar knew that he was doing this in Zero State, he would probably be stunned.

In order to be able to distinguish the microstructure of materials, he had to push his perception to the extreme, especially in terms of fineness. The scope of their activities in the past thirty days was not large, but the amount of materials Chen Mu felt unfamiliar with within this scope was not a small amount.

Plants, minerals, biological tissues...

These are all within the scope of his investigation. If it were anyone else, I would definitely not start from such a basic job, because this is really a huge project. But Chen Mu did not hesitate to choose this seemingly most laborious method.

Who knows how long they will stay in this ghost place. These tasks may seem tedious, but every time they do a little more, their chances of surviving in Baiyuan will be greater.

In the past thirty days, he could no longer remember how many battles he had experienced. There were many battles in which he was very likely to become a corpse, and his survival was largely due to luck. However, people cannot place their hopes on luck. He felt deeply how difficult it was to survive in this place.

He believed that it was necessary to prepare for a long battle. And these preparations are also the basis for their long-term battle.

For this reason, they had to slow down their progress. Chen Mu desperately used his perception to check these materials every day. I don't know if he used it too much, but the fineness of his perception improved very quickly. He became more and more proficient in this material identification method that was not recorded in any textbooks.

After several brushes with death, his Zero-Type state has also undergone qualitative changes. He can now be in Zero-Type state at any time without any discomfort. Those white lines also changed, becoming so pale that they were almost invisible. Hidden in the colored field of vision, he could easily and clearly feel these hard-to-see lines. Whenever there is danger, he can always detect it one step ahead, which allows him to avoid many dangers.

Under the pressure of death, the combination of [One Breath Perception Exercise Method] and deep tranquility exerted amazing power. His perception changed almost every day.

Life is boring. Every day is about fighting and checking materials. The devil woman seems to be used to this kind of life, and she is usually taciturn. However, the two have become more familiar with each other in battle, and their combined power has greatly increased.

Chen Mu was carefully collecting the poisonous powder from the fallen poisonous moth. The pink poison moth is quite large, with its wings spread out over 25 centimeters in length. Its body is brightly colored, especially its wings, which look like two rainbows. It doesn't fly very fast, but it creates a colorful poisonous area around its body. Any creature that breaks into this area will be poisoned immediately.

This is an extremely dangerous animal, but for Chen Mu, it is not a trouble. Using the [Bipolar Card], he easily killed the Pink Poison Moth. According to the devil woman, the colored poisonous powder on the poisonous moth is a very useful material, and many tribes buy it at a high price, mainly for making weapons.

This made Chen Mu very curious about it and deliberately collected the poisonous powder on it. All kinds of creatures in this area were almost wiped out by the two of them. Even the bone-spiked rhinoceros, which was so powerful that the devil woman didn't even dare to think about it, was killed by the two of them. But now the group of shadow bees would turn around and run away as soon as they saw the two of them, making Chen Mu marvel at the wisdom of these little creatures.

"Ha, this poisonous powder is indeed a good thing!" Chen Mu couldn't help shouting in surprise.

The materials he collected were only missing a catalyst. Unexpectedly, this poisonous powder turned out to be a natural catalyst.

The devil girl looked at Chen Mu who was overjoyed, and her mind was a little wandering. The speed and magnitude of his progress are truly astonishing! When he first arrived here, Chen Mu's strength was not as good as hers, but with almost every battle he experienced, his strength improved by one point. After more than ten battles, the gap between the two became even. But his momentum of improvement shows no signs of fading, and now he has become the main attacker among the two.

She has never seen such a powerful person! Is the talent powerful? Or does he have potential far beyond ordinary people?

Her strength was also increasing rapidly, but compared to him, it was a bit discouraging. This was after she possessed the Sky Star Vine.

After consecutively killing the fifteenth-ranked Black Serpent and the fourteenth-ranked Bone-spiked Rhinoceros, she suddenly felt that maybe they could really get out of the Abyss.

After collecting the poison powder, Chen Mu had already greeted her and returned to the camp. He couldn't wait.

The camp of the two was very simple, just a sheltered depression with the urine and hair of some powerful beasts sprinkled around it to prevent other beasts from breaking into the camp. The campground is very warm because of the firepit. However, what was burned in this simple fire pit was not wood, but a kind of light red stone. Chen Mu had never seen this light red stone before, but knew that it was an incomplete energy stone. I regretted for a long time that this light red stone did not contain much energy and could not be used to make energy cards. But then he had an idea and simply tried using it for warmth.

Unexpectedly, it is an excellent burning material. It is not only smokeless, stable in heat generation, but also extremely resistant to burning. The devil girl's eyes were rounded when she saw it, but she found out later after asking her. This is a very common stone, called red kite stone in Baiyuan Mansion, but no one would think of using it as fuel.

The red kite in the fire pit exuded warm heat, flickering in and out, reflecting Chen Mu's face, which was extremely focused.

In front of him, there were many strange things. There are various stones, plant tubers, unknown wild fruits, animal blood...

He began to process the materials. He had already drawn up a plan, so he moved very quickly without any hesitation. The devil woman looked at Chen Mu curiously. She had never seen a card maker make cards before. She has been in the Federation for a long time and has a certain understanding of many things in the Federation. She also knew very well what the energy cards meant to them.

Without Chen Mu as the main attacker, she alone would never be able to get out of Baiyuan!

This made her a little nervous.

Chen Mu's expression was calm and focused, and his movements were neat and orderly. It is hard to imagine that he is making cards from unfamiliar materials. If an uninformed person saw him at first glance, they would think that he has done this many times before.

The materials were changing in his hands, and various phenomena appeared one after another that stunned the devil woman.

The whole process took about four hours.

For four hours, Chen Mu's eyes did not shift at all, always staring at the simple and original container in front of him.

And the final product was the three cards he had just finished in front of him!
