After eliminating the parasites raised in the body by extraterrestrial demons, the vascular cave became silent, and there should be no more monsters in it. As for those parasites like black worms, they were either ground into meat pulp and pus sprinkled on the ground, or refined in the Tao environment by Ye Zan and others.


    In fact, just refining the power of these parasites is already a great harvest for several yuanshenjing who have the Tao realm. By refining the power gained by parasites, their Tao environment will become more stable, greatly reducing the risk of being swallowed by the fusion of heaven and earth.


    However, this is the corpse of a real immortal demon outside the sky. "Covered with treasure" is by no means an empty statement.


    "Brother ye, look at this..." after refining the last batch of parasites, Lin Lin grabbed something from the Taoist realm and asked Ye Zan to see it.


    Ye Zan''s eyes turned and fell on the things in the hands of the trees. It turned out that it was the wings of a long black insect. Although the size of the black long insects is not small, the wings that can support them to fly are very small, just like ordinary fly wings. Therefore, the small wings of trees must at least have hundreds of pieces.


    "You left this thing on purpose. Don''t you think those insects are disgusting?" Ye Zan asked jokingly.


    To be honest, the images of those long black worms are really not very good. They all look like enlarged black maggots, and they have the stench of a cesspit over the years. If you meet someone who is obsessed with cleanliness, I''m afraid you''ll feel dirty at a glance, and you''ll feel uncomfortable when you get closer, let alone splash them with slurry.


    However, the wings of those black insects, without the disgusting main body, are crystal clear, like ice flakes and snowflakes. Holding a small wing with his hand is like holding a handful of ice chips. I can''t see that they used to be so disgusting.


    "Those insects are disgusting, but these wings... As long as you don''t think about how they came from, it''s OK!" Lin Mu said, but he couldn''t help recalling the scene just now. His body trembled slightly, so he immediately said: "the key is that there are some hiding power in these wings. I think they should be useful."


    Those small wings can fly with such large insects and fly as fast as lightning. Naturally, they can''t rely on physical properties alone. As Lin Shumu said, those small wings themselves actually contain the so-called power of escaping from the air, which is used to support the flight of insects.


    This "power of escaping from the sky" is also a special power, which can be used in many places. For example, when refining the flying sword, if you increase the "power of escaping from the air", the speed of the flying sword will become faster. Also, for example, when it is difficult to lift heavy things even with spells, using this power to escape is to reduce the weight of items.


    However, at yezan''s current level, this power is actually useless. With the strength of their Yuanshen realm, adding this "hiding power" to the flying sword can not improve the speed of the flying sword. If they use mana to carry heavy objects, the things they can''t lift can''t be much lighter with the addition of "hiding power". Because of this, ye Zan didn''t care about the wings of those insects, but directly ground them together with the insects.


    Unlike Ye Zan, Lin Mu often looks at some things not from the point of usefulness, but from the point of interest. He thought the little wings were interesting, and he wouldn''t waste too much energy anyway, so he simply left them on purpose.


    "There are some uses, but it depends on who it is. At least for people like you and me, it''s really not very useful." Ye Zan doesn''t mean to pour cold water on it, but doesn''t want trees to waste their mind here. After all, there are too many really valuable things here.


    "Oh, brother ye, I know it''s useless for us, but if it''s used to refine some gadgets, it''s still good to give them to some future generations as a gift." Lin Mu said his plan with a smile.


    Speaking of it, linlimu has the lowest seniority in dazizong. The only peer is his sister. However, after arriving at yuqingzong, he became an "old master" in front of the disciples of yuqingzong because of his peer discussion with Ye Zan.


    Ye Zan lives in the war fortress for some reason to avoid embarrassment. After all, his generation in yuqingzong is too high, and everyone is always uncomfortable when they meet. However, Lin Limu has no "house attribute". He is a person who likes to play. In addition, he practices the Taoism of dazizong. Therefore, when linlimu was in yuqingzong, he often went to the main peak to play with his peers.


    Although you don''t have to give some gifts when you meet your younger generation, it''s necessary to reward a few gadgets occasionally to maintain your elder''s style. Unfortunately, although Lin Limu is a senior expert in Yuanshen realm, he doesn''t have many fragmentary things. Of course, ye Zan didn''t treat him badly, but all the things he gave him were useful to him. Such as Tiangang refining pill and Longmu, it''s impossible to give them to the younger generation.


    Therefore, this has become a "heart knot" of Linmu, which is to show off in front of those younger generations.


    "You! Be happy. It''s not a big deal anyway." Ye Zan shook his head and smiled helplessly after understanding the meaning of linlimu. He really can''t talk to the trees about this. After all, the Taoism that people practice is in their state of mind, so they can''t be confused.


    "Hey hey, brother ye, don''t worry. I''ll just get some gadgets. I won''t waste too much time on it." Lin Mu replied with a smile and received those wings into the heaven and earth ring.


    When things outside are over, ye Zan and his party come to the hole of the blood vessel cave, stand at the hole and look into the cave. Different from the bone cavity cave, there is no light in the blood vessel cave. It looks like a very deep and dark cave. The only thing is that when people stand at the entrance of the cave, they can smell a faint fragrance floating out of the cave.


    "It''s strange that those insects are so smelly. Why is there a smell in this cave..." Lin Mu slightly sniffed twice and said with a complicated face. Recalling that the insects came out of the hole, he was even embarrassed to mention the word "Xiang", so that he doubted whether there was something wrong with his nose.


    "Hehe, it''s actually nothing strange. When the aroma is strong enough to a certain extent, it will smell bad. This kind of thing is not uncommon. Do you know what the secular ambergris is? It''s said that it''s the vomit of whales, and it smells bad when vomited. It becomes a precious spice only after the taste fades." Ye Zan gave Lin Limu some funny examples to explain.


    "Is it smelly when it''s fragrant to the extreme? Then, according to your meaning, those insects smelled so much before, but they actually smelled too much?" Lin Shumu said obviously with an incomprehensible appearance.


    In this world, the study of things has not reached the molecular level, because there is no deep understanding of the components of smell. In the eyes of many people, fragrance is fragrance and smell is smell. This is a very natural thing and there is no need to study it deeply. Who cares what is in common between fragrance and odor? It is clearly the existence of two opposites.


    Of course, some saints also mentioned the theories of "things will turn against each other when they reach the extreme" and "water will overflow when it is full", but those theories belong to the philosophy of life, not the scientific research involving specific things. No one has applied such a theory to the phenomenon of human instinctive response, such as fragrance and odor. Naturally, there is no saying that "fragrance is extremely smelly".


    "Incense is still smelly. In fact, there''s nothing to tangle with. Anyway, smell the incense and bear the smell. Let''s go in and see what''s good in the blood vessel." Ye Zan can''t explain to Lin Lin specifically. He can only vaguely take the topic and turn back to business.


    "Oh, yes, I''d better see what''s inside." the tree nodded quickly.


    Although this blood vessel cave is narrower than that bone cavity cave, ye Zan and his party still don''t need to bow down. So, a group of people followed each other with "swaggering" and walked into the cave. As they walked, they looked around at the scene in the cave.


    The wall of the cave, of course, is the blood vessel wall. It is much smoother than the bone wall of the bone cavity, and it looks like a glittering and translucent luster. Of course, the luster was not emitted by the blood vessels themselves, nor was it inlaid with crystals, but reflected by the lighting spells used by Ye Zan and his party.


    Ye Zan reached out and touched the blood vessel wall, and then tapped it twice with his fingers. He felt that the blood vessel wall had a tough cortical feeling. It''s not surprising that this heavenly demon doesn''t have any diseases such as arteriosclerosis. Naturally, the blood vessel wall is smooth and tough.


    "The tenacity of this blood vessel looks no less than the skin of Tongtian wild beast. If it is used as a robe and armor for body protection, it is an excellent material." the Supreme Master Daoyuan touched the blood vessel wall and said. Speaking of it, he is a flesh and blood mechanism puppet, and his skin is the skin of a wild beast of Tongtian class. Naturally, he has a great say in this regard.


    "Well, what the elder said is right. Just such a blood vessel is enough to make hundreds of thousands of clothes and armor." Ye Zan nodded.


    In the end, ye Zan can only get 40% of the harvest, but that''s enough to "dress up" the disciples of yuqingzong. In addition, if ye Zan wants to do it, he will not simply make some leather robes. Instead, he will combine the technology of the world of science and technology and use nano war clothes as a template to make better clothes and armor.


    As for that, why use blood vessels to make armor, not to mention the skin of demons outside this day. You know, with such a huge body, the skin must be as thick as the city wall, or even better. Although such thick skin can be cut into thin slices and then used to make clothes and armor, it is still not as convenient as this blood vessel.


    Moreover, ye Zan has another plan for the skin of extraterrestrial demons, which is to enhance the defense of war fortresses. It may be extravagant to hide the skin of a real immortal extraterrestrial evil outside the war fortress, but it is absolutely valuable.


    Since ye Zan got the war fortress, he really regarded the war fortress as his home in the world, or a fundamental place where he can stand. Therefore, for him, no matter how much he spent on the war fortress, it was like decorating and protecting his home. Naturally, he would not be reluctant to give up.


    The party continued to walk into the cave, and gradually a fork began to appear in the cave. Blood vessels are responsible for transporting nutrients to all parts of the body. Naturally, they will not pass through to the end like bone cavities. However, compared with the aorta, the caves of those branches are naturally not so spacious, and some can''t get in at all.


    "Wait a minute, there should be something here." yezan suddenly stopped the crowd and came to a small hole next to the cave wall. This small cave is only about the size of a washbasin. Although it is not small, people can''t get into it.


    "Taoist friends have found something?" the supreme Taoist yuan turned back, came to Ye Zan, explored the small cave with his mind, nodded and said, "there is something in it!"


    "Brother ye, what is it?" the forest wood heard the speech and came together.


    "Don''t worry, I''ll know what it is when I scatter it and take it out." Ye Zan replied, then put his hand into the cave and gently patted the wall of the cave.


    For the things inside, although everyone has divine knowledge to scan and explore, they can''t find out what it is. Therefore, seeing ye Zan''s actions, everyone stopped asking more questions and waited quietly for him to take out the things inside.


    However, after a moment, ye Zan turned his face back, smiled awkwardly at the crowd, and said, "sorry, I almost forgot that this blood vessel can turn away my strength. I''ll get it another way."


    This is the corpse of the real immortal level extraterrestrial evil. The blood vessel is the blood vessel of the real immortal level extraterrestrial evil. Naturally, it can''t be as simple as tenacity. This blood vessel is also characterized by absorbing power to a certain extent, or absorbing and dissolving attacks. It is precisely because of this that ye Zan and the Supreme Master of Daoyuan said before that this blood vessel is a good material for making clothes and armor.


    For practitioners, what they need to defend is not only ordinary sharp weapon stabbing and cutting, but also their resistance to spells. Your armor, even if it''s really invulnerable, can''t hold others. A spell will blow you into slag.


    Ye Zan also didn''t remember for a moment. He habitually wanted to pass in the shock force and take out the things inside. As a result, when he clapped this palm, the concussion was like a clay ox into the sea. He didn''t even stir up some waves. Only then did he think of such a situation.
