Leaving the affairs of Muxi Town to others, Todd buried himself in the small building of the laboratory again.
Before officially starting to form the "Successor" army, there is one thing that needs to be confirmed first.
This is the human body's carrying capacity for "Sutherland bacteria". In other words, if a large amount of "Sutherland bacteria" is injected into a normal human body, will it cause adverse reactions?
The rationale for this question is that excessive use of anything may cause negative effects, let alone the human body, a carrier with extremely high requirements for precision and balance. To give some examples, such as ergotamine, triprol
For example, overuse of antibiotics will cause a decline in immune function in the body and promote bacterial growth.
Increased resistance to antibiotics leads to the emergence of superbugs.
As far as Todd knows, there are only three people who have been artificially injected with Sutherland bacteria by himself. One is himself, one is Huggins, and the other is Edgar. As of today, none of the three people have.
What adverse reactions occurred? However, the amount of "Sutherland bacteria" injected by the three of them was not large. Todd injected approximately 20 ml of bacterial solution, while Huggins and Edgar injected less than 15 ml.
So, the first thing to calculate is the number of bacteria contained in the bacterial solution.
To confirm the number of bacterial colonies, you need to use the plate counting method (CFU counting method, colony forming
units) to detect "Sutherland bacteria". The specific method is to serially dilute one milliliter of bacterial samples obtained from volcanic environment culture bottles with sterile physiological saline, and take appropriate dilutions (usually 3 dilutions
), inoculate the plate by coating method, and after a certain period of culture, count the colonies on the plate directly. This method can determine the number of viable microorganisms that can be cultured in the "Sutherland Bacteria" sample, so
This method is also called the "viable bacteria counting method" by microbiology.
Todd finally detected that the unit density of the "Sutherland bacteria" obtained in the volcanic environment culture bottle was approximately 170 cfu/ml (note that this refers to the number of colonies, not the number of bacteria). After conversion, Todd injected 3400
For each unit (170×20) colony of "Sutherland bacteria", Huggins and Edgar injected 2550 (170×15) unit colony.
Then here comes the problem.
Dig...approximately what is the maximum number of Sutherland colonies that the human body can carry?
Todd designed a drug tolerance experiment. The general idea is as follows. Inject "Sutherland bacteria" into mice and observe the maximum drug tolerance of the experimental subjects. Then based on the tolerance ratio of humans and animals, the calculation
Expand the body's bacterial tolerance.
What is the tolerance ratio?
The tolerance of humans and animals to the same drug is very different. Generally speaking, the tolerance of animals is greater than that of humans, that is, the dosage of medication per unit body weight in animals is often several times or even dozens of times that of humans. Therefore,
, to convert human dosage into animal dosage, the following ratios are generally used: human dosage is assumed to be 1 unit, 25-50 times for mice and rats, 15-20 times for rabbits and guinea pigs, 15-20 times for dogs and cats.
5-10 times.
The experiment officially began. Todd selected 5 white mice, all of similar age and roughly weighing 20 grams. Dilute 170cfu/ml Sutherland bacterial liquid ten times to 17cfu/ml, and inject the bacterial liquid once a day.
1 ml dose.
On the 9th day, after 9 injections of bacterial solution (a total of 9 ml, 153 Sutherland colonies), the mice developed anorexia, vomiting, and low energy.
On the 11th day, after 11 injections of bacterial solution (a total of 11 ml, 187 Sutherland colonies), the mice developed epilepsy and convulsions.
On the 15th day, after 15 injections of bacterial solution (a total of 15 ml, 255 Sutherland colonies), the first mouse died after 7 hours, and the second mouse died after 11 hours.
After autopsy and pathological examination of the mice, it was found that the experimental subjects mainly died of nerve infection caused by bacteria.
It seems that the "Sutherland bacteria" are not used casually. Indiscriminate abuse of large doses will cause unpredictable serious consequences for the host.
Next, we began to calculate the upper limit of human tolerance. The mice developed symptoms on the 9th day and were injected with 153 Sutherland colonies. Calculated based on the ratio of human and mouse tolerance, 153 was divided by 37.5 (
Take the median value of the interval), which is approximately equal to 4.
The weight of a mouse is 20 grams (0.02 kilograms), and the weight of an average human man is 75 kilograms. The weight ratio of the two is 1:3750, and the tolerance of Sutherland colonies of an average man is 15,000 (4×3750).
That is, once there are more than 15,000 Sutherland colonies in the human body, pathological symptoms will appear.
According to Todd's body condition, 3,400 Sutherland colonies can suppress 3 kinds of superpowers. So after conversion, 15,000 Sutherland colonies can suppress 13 kinds of superpowers. If we make a conservative adjustment, we can get a 75 kilograms.
An adult man can have about 10 kinds of powers at the same time.
Through this Sutherland bacteria tolerance experiment, Todd finally reached the following conclusions:
A 75 kg man was used as the control.
1. The upper limit of Sutherland bacteria that humans can tolerate is 15,000 colonies (this level may already cause pathological symptoms). If the density of Sutherland bacterial liquid is 170cfu/ml, the maximum injection volume is 88.25ml.
Second, once humans are injected with more than 15,000 Sutherland colonies, nerve infections caused by the bacteria will occur. The initial symptoms are anorexia and dullness, the mid-term symptoms are epilepsy, and the late-stage symptoms are neuronal degeneration and death.
Third, the upper limit for human beings to accommodate superpowers is 13. To be on the safe side, it is conservatively estimated to be 10.
In a word, if a human being is transformed into a "successor", he can have up to 10 kinds of powers. If he exceeds this number, he may become ill.
After determining the upper limit of abilities that "Successor" can carry, the next step is to determine what abilities it should carry.
Todd made a statistics. After repeated testing and screening, there are currently a total of 18 types of valid and available abilities in the "Ability Library", which are divided into three major categories according to the type of ability.
What Todd needs to consider now is, from these 18 kinds of powers, which powers will be extracted and injected into the 13 "successors" headed by Huggins?
The selection criteria are as follows:
First, try to choose abilities whose manifestations are not obvious. After all, abilities that are too flamboyant will reveal the identity of the alien and attract attacks from the church and the secular world. Therefore, elemental attack abilities cannot be selected.
Second, it should adapt to the knights' combat method. Considering that the terrain around Muxi Town is mostly plains, the group charge of the heavily armored knights will be the main means of combat, so when it comes to power selection, charge should be chosen more often.
class and protection class powers.
Third, pay attention to the number of abilities and leave vacancies for the later stage. The upper limit of the abilities of a "successor" is 10, but if all 10 abilities are loaded now, once more excellent abilities appear in the future,
Erasure and replacement will not be possible, after all, Todd does not yet have any method at hand to remove the alien ability from the body.
After much thought, Todd finally selected three alien abilities for the 13 "successors", namely "regeneration", "resistance to pain", and "metal skin".
In addition to this team, Todd also plans to equip them with a scout - Edgar. In addition to the opponent's existing "Speed", he plans to inject "Night Vision" and "Eagle Eye" into the scout.
able.
After making the above decision, Todd found these 14 people and held a meeting in the side hall of the church. He stated his plan to them and explained some of the processes and risks involved.
He is not worried about Huggins and Edgar. What makes him a little embarrassed is the 12 Huggins' former subordinates. Because these people are not aliens, they are all normal people, so let them accept the bacteria.
Transformation, both emotional and rational, is an order that goes beyond the normal scope.
To Todd's surprise, after listening to his words, 12 sergeants expressed their willingness to receive the injection immediately.
After repeated confirmation by the priest, the sergeants still insisted on their opinions.
Finally, these 14 people were transformed by the bacteria of the "Successor" in three days. Except for one sergeant who had a strong rejection reaction when receiving the "Sutherland bacteria", but with timely treatment, he was fortunately able to survive.
No big deal.
At this point, including 1 (former) knight, 12 (former) sergeants, and 1 (new) scout, the first combat team of the Muxi Knights was officially established.
After handling this matter, Todd instructed Huggins to start recruiting peasant soldiers and believers in Muxi Town. Peasants and soldiers were mainly responsible for the management and operation of the Knights' religious property in peacetime; during war, they were mainly responsible for supplies.
Transportation, and sometimes responsible for cleaning up the remaining soldiers and cleaning the battlefield. The believers are generally responsible for
They are the basic military force of the church organization. They are composed of devout catechumens. They usually conduct combat skills training and formation arrangement under the leadership of church knights; in war, they will follow the knights and sergeants as knights.
The military force of the third echelon of the regiment is engaged in combat.
After these matters were dealt with, the time came to the end of September and beginning of October in the 1170th year of the Christian calendar. It was less than two weeks before the ecumenical council of the Papal States and the official oracle announcement of the Knights of the West.
On the morning of this day, Todd walked on the streets of Muxi Town, watching Joe and the monks measuring the land red lines and the distance between houses, while discussing the street planning and building design with the craftsmen headed by old Aiden.
Layout; Huggins and the sergeants led a group of 68 catechumens to conduct basic formation training in an open space not far away; Alfonso was on the hills in the distance, holding a big sword and struggling
are doing physical training.
Todd himself, as agreed, came to the dining table on the first floor of the hotel on the first day of the opening of Rachel and Karin's "Sister Hotel", looked at the dazzling array of dishes on the menu, touched his withered belly,
When I was thinking about what to eat, a figure stumbled in at the door.
Todd raised his head and took a closer look, and it turned out to be the new scout with a panicked look on his face - Edgar.
"Cavalry! Many cavalry are coming towards the town!"
Hearing his words, Todd quickly put down the menu in his hand, walked out of the store, walked to the square, and looked into the distance along the street. Using the power of "Eagle Eye", Todd clearly saw twenty-something people on the plain.
A heavily armed knight with a silver ring flew towards Muxi Town.
When Todd saw this scene, the first thought in his mind was - are these people crazy?
The armies of the secular kingdom have invaded the territory of the church without permission. Is there anyone so arrogant that he is an enemy of the entire church?
When the team got closer, Todd saw something strange. The old knight leading it had white hair and beard, was covered in blood, and had a few arrows stuck in his armor. He looked like he was Baron Cumberland.
, there was another person sitting behind him. Todd tried his best to distinguish, that person seemed to be a young woman, wearing a luxurious palace dress.
When Todd saw clearly who the woman was, he couldn't help but take a deep breath.
