Jiang Wu swallowed hard and asked, "Qingyu, is this thing difficult to manufacture?"
Ye Qingyu said seriously, "The difficulty is not too bad, the key is to be careful. However, this thing has a drawback: it will destroy the crystal cores in the brains of zombies within the blast radius, unlike ordinary bombs, which can hardly destroy energy crystal cores."
Jiang Wu understood Ye Qingyu's meaning: this thing was too powerful and could only be used to simply eliminate zombies.
As before, even if tens of tons of TNT were buried under the feet of zombies, after the explosion, many undamaged energy cores could always be found.
The energy crystal core will only be destroyed if it is at the epicenter of the explosion.
However, with this type of crystal core bomb, the crystal core will be destroyed as long as it is within the blast radius.
If you don't care about the crystal nucleus, then so be it.
But Jiang Wu is now dreaming about crystal cores, and he is desperately short of them.
Using crystal core bombs to kill zombies not only wastes crystal cores, but also fails to yield the crystal cores from the killed zombies.
This back-and-forth resulted in a huge loss.
Ye Qingyu continued, "This kind of level one energy crystal core bomb can kill a T2, but it cannot damage the leather of a level two evolved beast, so it is almost ineffective against level two evolved beasts. If you want to use this kind of crystal core bomb to kill a level two evolved beast, you need to use a bomb made from a level two crystal core."
After saying that, Ye Qingyu took out a large, egg-shaped grenade painted gray and introduced it: "Honey, this is a crystal core grenade made from a level 2 energy crystal core. Its power is comparable to that of 100 kilograms of TNT. Moreover, due to its special properties, it is much more lethal to level 2 evolved beasts than TNT of the same amount."
Then, Ye Qingyu took out an even larger, grayish-blue, egg-shaped grenade and introduced it with a solemn expression: "Honey, this is a level three crystal core grenade. Its power is comparable to the explosion of 2,000 kilograms of TNT. It is very dangerous, and I do not recommend its production."
"If things get out of control, even with our Level 3 bio-armor protection, we could still lose our lives, unless we can become Level 4 evolved beings."
Jiang Wu was initially quite surprised, never expecting that such a small crystal core bomb could be equivalent to 2 tons of TNT.
But upon hearing the rest, he asked in surprise, "Why can becoming a Level 4 Evolver withstand such a crystal core bomb?"
Ye Qingyu shook her head and said, "It's not about completely enduring it, but relying on various protections and physical constitution to have a chance of survival. However, I can't be sure, because I don't know how strong a level four evolver is."
She carefully placed the grayish-blue oval grenade aside and continued to explain, "Recently, I discovered the secret behind the incredibly tough structure of the skin of high-level zombies and evolved beasts. It's a mysterious molecule that I've named Source Matter."
"With current methods, the existence of source molecules cannot be detected. It is like dark matter, which cannot be explored. However, through electron microscopy, I found that as the level of biological evolution increases, the proportion of biological cells decreases, while the gaps between biological cells increase. This is unscientific."
"I suspected that there were other undetectable substances inside, so I began to study that mysterious substance."
“The average weight of a normal cell is 2-3 nanograms. After calculating the weight, I confirmed the existence of that mysterious substance. Its weight for the same volume is more than half that of a normal cell.”
"The more of this substance there is, the tougher it becomes. It especially likes to accumulate in keratinocytes, which is why the skin is much harder than the flesh!"
"The amount of this source substance in the teeth and claws of giant beasts is outrageously large, making the teeth and claws of giant beasts indestructible."
"The reason why bullets and ordinary bombs are less effective at damaging the behemoth's skin is because that source material has a natural suppressive force on the molecular structure of existing matter on Earth."
"That source energy is like a kind of magic that doesn't belong to our planet, and the best way to defeat this magic is to destroy it with something that also possesses source energy!"
"The higher the biological level, the higher the density of this source matter. If we could possess a claw or tooth of a level 5 evolved organism, the source matter content inside would be enough to crush the source matter contained in the skin of level 3 or 4 organisms, and we could easily cut through their skin."
"On the contrary, the amount of source matter contained in the claws of level two organisms is not enough, so it is difficult to use their claws to harm level four or five organisms."
"From the current perspective, it's less about biological evolution and more about all living things striving to obtain this source substance. The more source substance a person has, the stronger they are! Therefore, I call this mysterious thing source substance!"
At this point, Ye Qingyu sighed, gave a bitter smile, and said, "Husband, there's something I don't quite understand. We humans are also biological organisms, but after we evolved, the amount of source matter contained in our bodies is far lower than that of other organisms..."
"I don't quite understand why, after humans turn into zombies, as the zombies evolve, they develop energy crystal cores in their brains, and from then on, the source matter in their evolved bodies is far superior to that of humans of the same level."
"It's as if this source substance is deliberately targeting us humans. On the contrary, the dumber the creature, the easier it is to obtain and accumulate source substance."
"The dumbest of the evolved zombies are the T-type zombies, so the amount of source matter in their bodies is much higher than that of the S-type zombies."
"Type N zombies are more intelligent, and they also have the lowest amount of source matter in their bodies..."
"The only explanation now is that the human brain is too amazing. The source matter in the body is absorbed and utilized by the brain, while the zombie's brain, unable to withstand the source matter, was completely destroyed and turned into an energy core..."
"But these are just my guesses; I can't verify them..."
"I don't know how the zombie virus came about..."
Jiang Wu and Mi Qingying were already stunned.
They had no idea that there were so many things they didn't know.
Taking a deep breath, Jiang Wu hugged Ye Qingyu and exclaimed, "Qingyu, you're amazing! No wonder people say that scientists are a valuable asset to all mankind. Now I finally understand what that means."
Ye Qingyu kissed Jiang Wu and continued, "Husband, the Radiant Immortal Tea has been successfully processed. It retains the biological activity and can be preserved for a long time. The Blood Vine Tree has also been successfully cultivated, but unfortunately it can only grow on the side where we found it. There should be a substance in the mountains and forests over there that we haven't found yet."
"The antidote you gave me, I extracted a similar molecule from a plant. It has some effect on the zombie virus, but it cannot be used as an antidote. It's a pity I don't know what other substances that scientist used back then."
"I want to study more biology; there's so much to do, I always feel like there's not enough time..."
