Wang Yilan used the strength of milk to split the hard skull, searched for it in the bloody brain, and soon became covered in blood. Pen, fun, and www.biquge.info

Everyone basically has no disgust and discomfort with this picture, only Mu Yin, she has always been not very bold, she doesn't even dare to watch horror movies, and she has never seen such a bloody scene. She couldn't help but take two steps back, a little dizzy and nauseous, her chest and abdomen couldn't breathe, and her stomach juices were surging, and she almost vomited her lunch. With Shang Rou's support, she barely stood firm.

Shang Rou persuaded: "Miss, you don't dare to look at it, let's go back." ”

"No!" Mu Yin's curiosity suppressed fear, and his voice was a little timid, but extremely resolute: "Let's take a look and see what he has to do." ”

"Is this important?" Duan Xue leaned into Su Jiangchen's ear and asked softly, "You should go back to your room now to rest and recuperate, and you can talk about other things later." ”

Su Jiangchen kept staring at the corpse of the mutant deer: "It's very important, look at it carefully." ”

Wang Yilan turned the mutant deer's mind upside down, but he didn't find what Su Jiangchen said.

"Cut open its ribcage and look near its heart."

Wang Yilan searched for a long time, but still didn't find it, and almost became a bloody person.

Mu Yin kept covering his mouth, feeling that the lunch he ate was in his throat, and he couldn't go up or down. Shang Rou kept patting, rubbing, and touching her back, so that she didn't spit it out.

It's not here, so where should it be?

Su Jiangchen thought quietly for a moment, and finally his gaze stayed on the bulge on the top of the mutant deer's head and between the two antlers: "Look there!" ”

It was an unusually hard area on the deer's head, Wang Yilan's physical strength had been consumed, and this time, with the help of Yafei, the two worked together to cut the skin and bones there with difficulty.

"Found it, there's really one of the kind you said!" Yafei pinched a bloody sac and handed it to Su Jiangchen.

Finally found it, Su Jiangchen held it, and felt a little excited.

There are three treasures in the evolution of the last days, and the New Year is good to the Beast Sac.

The marrow is the bone marrow in the second cervical vertebrae of zombies, which contains the element X, which can upgrade the abilities of the Adept after consumption.

Happy New Year refers to the mysterious appearance of the Y element in the air every New Year, which is a dangerous double-edged sword capable of infecting humans into zombies and creating a new group of supernatural beings.

And now the thing Su Jiangchen is holding in his hand is the beast sac in the "Happy New Year of the Lost Marrow Beast Sac", which looks small in size, but the weight is not light, and it can almost catch up with a lead ball.

The sac is the organ that stores the element X in the body of the mutated organism, and is another energy organ in addition to the heart. It is a liquid on the inside, and the capsule on the outside has very good toughness and elasticity, which can protect the liquid inside from breaking and flowing out.

Unlike the marrow, the sac does not have a fixed growth location in mutated organisms, and is mostly produced in the heart and brain, but it may also grow in other places depending on the species of organism, and the regularity is not obvious.

For this reason, in previous lives, if you were not a zombie hunter or a professional researcher in mutant organisms, when people hunted a mutant organism, they would often search for its entire corpse to find the animal sac, and the mutant creatures often had rough skin and thick flesh and huge size, which made the search difficult and time-consuming.

Each mutant creature has a sac in its body. Corresponding to the level of mutated creatures, the sacs in their bodies are also divided into different levels, and the element X contained in them increases with the level of the sac.

Because they all contain element X, in this regard, they have the same effect as the marrow, which can make the ability of the ability to upgrade, and although its taste is not good, it is undoubtedly like the gap between Kung Pao chicken and poop compared to the marrow, which is 10,000 times better, and there are almost no side effects.

Unlike the zombies on the Rotten Street, the number of mutated creatures is scarce, so the price of the beast bag is much more expensive than the death marrow.

But this is not the greatest value of the existence of the beast sac.

Its greatest value lies in the fact that a very small part of the animal sac contains a certain amount of Y and Z elements in addition to X elements.

When the beast sac was discovered, after a period of research by Dr. Ye, it was found that those special beast sacs containing the Y and Z elements were taken by people, and the person would produce abnormal abilities and become supernatural.

This was a discovery that made countless people rejoice and go crazy, and it also made it possible for an ordinary person to awaken into an alien.

Think about it, when countless people see that other people have become supernatural beings, not only do they have no pressure to survive in the last days, but they also have a thriving relationship, they will have crazy, irrational jealousy and hatred, resentment, blame the world for being unfair, and life is very different: why is it that everyone has the same conditions, but the person who becomes the supernatural is not himself!

Before the end of the world, others were born with a golden key, and they grew up to be the second generation of rich, while they were born in a poor family and struggled for decades and were still at the bottom of society.

After the end of the world, others have become supernatural again, calling for wind and rain, omnipotent, and struggling on the line of life and death, still the lowest level of society.

Princes and generals, would you rather have a kind?

Dr. Ye's discovery ignited a long-suppressed desire in their hearts, and during that time, people began to use various means to hunt mutated creatures frantically, hoping to find a special beast sac to make themselves an alien, and also to get ahead and soar into the sky.

It was a wild, dark, gloomy history in the X era.

The strength of mutant creatures is not something that ordinary people can easily defeat, even a well-equipped squad, so humans have lost a lot of valuable people in vain.

When a group of people killed a mutant creature by luck, in order to snatch the beast bag that might turn themselves into an alien, they began to kill each other in spite of the feelings of fighting side by side and the friendship of comrades-in-arms, and more people died at the hands of their own people.

Unfortunately, there is another key problem, humans do not know which beast sacs are special beast sacs that can produce abilities after taking them, and the vast majority of people eat the beast sacs, but they do not become supernatural beings, and they have paid a huge amount of effort and crazy killing in vain but there is no return.

After ordinary people take too much marrow or animal sacs, the content of X element in their body will seriously exceed the standard, and the energy carried by X element will accumulate in the body, get out of control, flow around, tyranny, destroy body functions, and in the most serious case, it will explode and die.

This makes it a very dangerous, high-input, low-output thing for those lucky or powerful people to obtain the beast sac through various means and then blindly take it, and at this time, the crazy plundering of the beast sac is over, and more than 1 year has passed since it started.

Dr. Yip called the tragedy caused by the discovery a "global bloodbath caused by animal sacs" and publicly apologized to all mankind for this. It was also after that that most of the inventions and discoveries in Dr. Yip's laboratory were kept secret from the public, which delayed the overall scientific and technological progress of mankind and the utilization of scientific achievements, but also prevented such things from happening again.

In the 9th year of the X era, some big forces obtained the instruments used to distinguish between ordinary beast sacs and special beast sacs from Dr. Ye, so that humans could make batches of supernatural beings, but in fact, in the 10th year of the X era, the road to evolve into high-level supernatural beings was blocked, and many of the supernatural beings produced in this 1 year did not play much role in the desperate battle between humans and high-level zombies in the last few years of the X era.
