In fact, as early as when he studied the information sent by "Liu Yizhen" before, Li Heng understood that he had encountered a resource crisis.

In other words, the resources at his disposal were no longer enough to support some of his subsequent experiments and practices.

It's not so much about money, it's about being an independent private "researcher", and what he can get so far is his personal limit.

"Liu Yizhi" mentioned in the information that several special experimental reagents and special drugs were needed in the follow-up experimental methods, and Li Heng had no means to get them.

However, "Liu Yizhen" still thinks that he is a doctoral student in a biological laboratory of Northwest University, and naturally thinks that it is still possible to get these things by applying to the project leader or supervisor.

So looking at many plans, Li Heng could only sigh with admiration, and even once rose, should he take some risks and go to a special channel to get it?

But he didn't do it in the end, the risk is small, the exposure is big.

Later, he decided to choose to take another path, that is, to find a similar substance as a substitute, as much as possible within his normal reach.

Among them, the secretions of natural organisms are a good choice.

There are thousands of strange creatures in nature, and their bodies are completely different natural chemical plants, and all kinds of strange chemicals are synthesized in their organs and glands, and many of them are even impossible to replicate in the human chemical industry.

Finding substances with similar chemical properties and then using them to replace the pharmaceutical drugs mentioned in "Liu Yizhen" is something that Li Heng has been considering.

And there are also certain eyebrows before, for example, the nerve receptor agent similar to methamidochlorone mentioned in the data can be replaced by the product of filtration and hydrolysis of isolated snake venom protein, the two have similar properties, and the aspiramin for the regulation of cell permeability of epithelial tissue cells can be replaced by acidic secretions of some insects and arthropods, and the sodium potassium triacylphosphate solution for the respiratory tract uses the flora of some reptiles to decompose specific plant fibers to obtain an approximate solution......

Li Heng also did a lot of such investigations, but he soon found that most of the creatures could not meet his ideal needs.

Several very important chemicals cannot be sufficiently effective by ordinary organisms alone, and the concentration of biomass they secrete cannot reach the level that Li Heng wants, even if they are purified, they are very sufficient.

So he's always looking for big, strong, and powerful "big guys" to make the chemicals he needs!

Fortunately, providence favors them, and now, these "benevolent brothers" are obediently lying in the mansion that Li Heng bought for them, and they are entertained with delicious food and drink.

But this is not for nothing, and after eating, all that is left is to work for yourself.

The first to bear the brunt was the black-veined pit viper with the thickness of the child's arm, and the moment it opened the lid of the glass box, it suddenly jumped out, obviously waiting for the opportunity for a long time to give Li Heng a ruthless time!

But Li Heng didn't even lift his eyelids, he pinched it with his backhand, and the nearly two-meter-long snake body was wrapped around his arm twice, like a lifeless hemp rope, and then his fingers pinched it slightly, and the snake's mouth was opened, and the two bright fangs were buckled on the wall of the beaker, and wisps of translucent snake venom protein liquid overflowed and were collected in the beaker.

And the fierce and terrifying black-veined pit viper, which was also a top predator, was held in Li Heng's hands at the moment, like a large earthworm, without any temper.

After milking a cow for several minutes, and after making sure that it couldn't be squeezed again, Li Heng casually put the long snake back into the glass container.

The originally murderous black snake was stunned at the moment, as if it had been squeezed dry, and it was staggering inside.

Immediately followed by the next "benevolent brother", Li Heng made a closed container in the shape of a small mouse out of plastic, and threw it into the glass container of the hundred-legged centipede.

With each sting, its venom penetrates the holes inside the plastic and remains in the storage balls inside.

When he arrived at the toad brother, Li Heng gave it a back rubbing service to collect the venom secreted by the pimples on its back.

As for the gecko itself, it is not poisonous, but there is a special class of bacteria in its urine, and those bacteria will produce toxic substances, but this kind of bacteria has other uses for Li Heng.

He took the gecko's urine, and then used his own medium to grow the bacteria, and when the colony had multiplied to a certain size, he added other substances and various plant fibers.

And the black scorpion, which was bigger than a palm, was directly chopped off by him with the poisonous needle of the scorpion tail, after all, this is the only one that is a disposable product, and there is no need to take poison repeatedly.

Snake venom, its main components are a variety of poisonous proteins and polypeptidases, subdivided into various components are very complex, there may be dozens or hundreds, but according to the classification of the effect can be roughly divided into two categories: blood circulation toxins and neurotoxins.

The venom of the pit viper is a neurotoxin, which affects the binding of neurotransmitters, and the venom collected by Li Heng has a toxic concentration far exceeding that of ordinary snake venom of the same species, and the trans-polymeric chain polypeptides generated after hydrolysis reaction can be separated by centrifuge.

The toxin of centipede is a complex acidic fusion substance liquid, including hemolytic protein, histamine and lipids, etc., among which hemolytic protein and histamine have the effect of significantly changing the cell permeability.

As for the toad, this ugly appearance is greater than the terrible guy, many people think that this thing is not very poisonous, at most it is the feeling of making the skin itchy and allergic to grow a big bag, and the deterrent power is far less than that of poisonous snakes, centipedes, scorpions and other creatures that make people feel terrible on the outside.

But this is definitely an underestimate, the toad is no less toxic than any other poison, and some people even believe that the toad is the first of the five poisons!

The dienol compounds in toad toxin have a biochemical mechanism that directly acts on the cardiovascular and cerebrovascular vessels, and can affect human structures such as nerves, myocardium, respiratory tract and even the digestive system at the same time.

The last scorpion tail was kept by him in a dehumidifier and dehydrated and air-dried.

Five poisons have been used in medicine since ancient times.

The five poisons are killed and the remaining corpses are used as medicinal materials, either grinding, soaking, or boiling, but the ancient method is too crude.

Li Heng's use method is to combine the methods of modern biochemical medicine, starting from the microscopic ingredients, and maximizing the use of their respective products in the most delicate way, rather than smelting and swallowing dates, so that those complex and diverse compounds can undergo various uncontrollable metabiotic reactions in the body.

"If it succeeds this time, I can get out of my current 'drug' career and use the power of the five poisons to reshape the mechanism cycle of the inner heaven and earth, and no longer have to rely on energy-efficient substances."

In the hum of the centrifuge, Li Heng looked at the increasingly full test tubes and the five part-time "brothers" with hope.

"However, before I try this "Five Poisons Elixir", I have to solve some mundane things first."

His eyes were on the village, on an old, dilapidated bungalow, the only person he could still consider a relative.
