Before a new drug is put on the market, it must be tested on multiple healthy people. New drugs must go through basic research, animal testing, and human clinical trials before they can be put on the market. In clinical trials, researchers conduct tests on new drugs and treatments on subjects through active or no intervention, and obtain relevant information through data analysis and symptom observation.
Before the revival of spiritual energy, China had more than 800 new drugs undergoing human trials every year, involving about 500,000 people.
For the development of CPH4, basic research has been completed, so the next step is animal testing, and then human clinical trials.
Ordinary animals are naturally not qualified to use CPH4. The big white goose of the second teacher in the academy does have some qualifications, but it is not easy to use it. The awakened animals on the earth are also not easy to use. Therefore, Yi Xiaochuan can only go to the world of cultivation again.
In the world of cultivation, there are monsters and beasts, and being guinea pigs is the best thing to do.
Yi Xiaochuan had never taken the seven major sects of cultivation in Yue Kingdom seriously before, and he didn't want to destroy them and steal their treasures. He just wanted to find a place and do experiments behind closed doors.
For such testing grounds, some forbidden areas are naturally the best places.
First of all, there are many spiritual beasts.
Secondly, you won’t be disturbed by others.
The forbidden area is not off-limits to people forever, but it is impossible to get close to it under normal circumstances. Only at a specific time and place can one enter with the help of the leaders of the seven major cultivation sects of Yue State.
Some spiritual medicines have become scarce in the world of cultivation long ago, and have completely disappeared from ordinary places. Now the only place where they can still be found are those so-called forbidden areas.
Since they are called forbidden areas by cultivators, these places must be extremely dangerous. They are generally located in remote places with harsh environments. Some are the lairs of demons, and one must kill all the way before passing through. Others even have some ancient prohibitions, and one must work hard to break the prohibitions before having a chance to enter.
The main ingredients for the foundation-building elixir of the Huangfeng Valley and other Yue Kingdom's cultivation sects over the years all come from the latter kind of forbidden area, a place that has been sealed off by an ancient wind-attributed ban.
The prohibition there is very powerful. Originally, their sect was unable to open it with their strength. But later, somehow, it was discovered that the prohibition would have a five-day weakening period every five years. During this period, if several Jindan stage cultivators cast spells together to break the prohibition, they could temporarily open a passage to allow a certain number of people to enter.
But when the passage was opened and all the cultivators tried to go in, another accident occurred.
All the cultivators who had reached the foundation building stage were blocked outside by another strange restriction in the inner layer, while those who were at the Qi Refining stage entered without any hindrance, collected a large number of rare elixirs, and brought them out.
This discovery immediately caused a sensation in the Yue Kingdom's cultivation world, and so the seven major sects sent a group of disciples below the foundation-building stage into the forbidden area every five years to collect a large number of spiritual medicines. Of course, the main medicine for the foundation-building pill was the most important of them.
Due to the existence of two ancient forbidden spells, this small world called the "Blood Forbidden Trial" is not guarded by the seven major sects of Yue State.
Why is this so? Because if any faction dares to send people here, the other six factions will never give up.
Do you want to keep it for yourself
How can this be!
What may eventually be triggered is a war, where people will attack together.
Therefore, it was agreed that each faction would only come here once every five years, and the rest of the time, everyone ignored this desolate mountain and wilderness area.
Besides, except for those few days, no one can get in at normal times.
Unfortunately, Otoshi Ogawa went in.
Banning this thing is a headache for many people.
But, Xiao Yi said that he is a walking bug...
Code deciphering and energy absorption are the nemesis of prohibition!
…
Inside the forbidden area, in the central area, is a huge circular mountain range, which is tightly blocked by pitch-black fog all year round.
In this mountain, there are natural sacred places such as caves, valleys, and cliffs, as well as artificial buildings such as stone houses and stone halls. All kinds of magical medicines from heaven and earth grow in these places.
In Otogawa's opinion, this should be the ruins of an ancient civilization.
Unfortunately, there is nothing left now, only some magical herbs and medicines, and countless monsters.
A unique testing ground.
In the forbidden area, from the lower-level Fire Rat and Wind-Chasing Rabbit to the top-level Golden Python and Ice and Fire Wolf, it includes almost all the first-level monster species that the seven major sects have heard of or not heard of.
Several simulated robots walked out of the thick fog, with traces of burns on their bodies. However, on the cart behind them, lay a huge wolf-like creature. It was not dead, but was knocked unconscious by a highly effective anesthetic.
Right in front of the robots, a huge arena building was built inside a huge stone temple.
A red shadow kept shuttling back and forth in the thick fog.
"Failed again? It's become a zombie, but its speed has more than doubled..."
Yi Xiaochuan muttered, looking coldly at the blood-red shadow that pounced on him, and with a point of his finger, lines of spiritual energy turned into chains that bound the shadow.
When it was completely captured, it turned out to be a zombie-like beast. Most of its skull had been corroded and broken by its surging brain. The muscles on its body were also bulging out, and even its tough skin was torn, revealing the bright red muscles inside!
"fail!"
Xiao Yi sighed and waved his hand slightly. The binding spiritual energy lock suddenly tightened and turned into a sharp blade. In an instant, the horrible zombie beast was cut into thumb-sized pieces of meat.
A magical power created by simulating the well character.
Then the cleaning robot cleaned up and burned the minced meat to ashes.
The wolf-shaped creature was transported to the laboratory, but Otokogawa was not in a hurry to start the experiment.
The physical body of the first-level monster is still too weak and must be cultivated first, otherwise it will not be able to withstand the power of cph4's secondary evolution.
Moreover, Otoshi Ogawa is also preparing to summarize the experimental data.
The energy contained in CPH4 alone is really like an atomic bomb. If it is forcibly injected and absorbed, there is only one outcome, and that is to be shattered into pieces.
It is necessary to find a substance that can suppress its powerful energy, allowing it to slowly release its power, transforming it from an uncontrollable state to a controllable state, and transforming it from an atomic bomb into a nuclear power plant.
And this substance is found in Tongtian Pills.
But experiments have shown that it is not a simple digestion and absorption, but a complex chemical reaction occurs after entering the human body.
No one knew how much time had passed. Han Li refined a lot of pills and took a lot of medicine. Yi Xiaochuan finally came out of his research state, stretched his body, and glanced at the attribute panel.
"Well, math has finally reached level 5!"
