Handing over the affairs of Muxi Town to others, Todd buried himself in the small building of the laboratory.

　　 There is one thing that needs to be confirmed before the official start of the formation of the "successor" army.

　　 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 principle of this question is that the excessive use of anything can cause negative effects, let alone the human body-a carrier with extremely high requirements for precision and balance. To cite some examples, such as ergotamine, triptan, and opioids, excessive use of them will lead to headaches, muscle spasms, neurological psychedelic vision, addiction and other reactions; another example is antibiotics, excessive use will It triggers a decline in the body's immune function and increases the resistance of bacteria to drugs, resulting in the emergence of super bacteria.

　　As far as Todd understands, there are only three people who have been artificially injected with Sutherland bacteria. One is himself, one is Huggins, and the other is Edgar. As of today, none of the three have had any adverse reactions. However, the amount of "Sutherland bacteria" injected by the three was not large. Todd probably injected 20 ml of bacterial liquid, while Huggins and Edgar injected less than 15 ml.

　　The first thing to calculate is the number of bacteria contained in the bacterial liquid.

　　If you want to confirm the number of bacterial colonies, you need to use the plate counting method (CFU counting method, colonyformingunits) to detect "Sutherland bacteria". The specific method is to serially dilute one milliliter of bacterial samples obtained from a volcanic environment culture flask with sterile physiological saline, take the appropriate dilution (generally 3 dilutions), and inoculate the plate with a coating method. After a period of incubation, count the colonies on the plate directly. This method can determine the number of live microorganisms that can be cultured in a sample of "Sutherland Bacteria", so this method is also called "Live Bacteria Counting Method" by microbiology.

Todd finally detected that the unit density of the "Sutherland bacteria" obtained in the volcanic environment culture flask was about 170cfu/ml (note that this refers to the number of colonies, not the number of bacteria). After conversion, Todd injected 3400 With a unit (170×20) colony of "Sutherland Bacteria", Hudgens and Edgar injected 2550 (170×15) colonies.

　　 Then the question is coming.

　　 dig... What is the maximum number of Sutherland colonies on the human body?

　　 Todd designed a drug tolerance experiment. The general idea is as follows, inject "Sutherland bacteria" into the mice to observe the maximum drug tolerance of the experimental subjects. Based on the tolerance ratio of humans and animals, the bacterial tolerance of the human body is calculated.

　　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 amount of medicine used per unit body weight is often several times or even dozens of times that of humans. Therefore, to convert the amount of medicine used by humans into the amount used for animals, the ratio is generally as follows: The amount of medicine used for humans is assumed to be 1 unit, 25-50 times for mice and rats, 15-20 times for rabbits and guinea pigs, and 15-20 times for dogs and cats. 5-10 times.

　　The experiment officially began. Todd selected 5 mice, all of the same age, weighing roughly 20 grams. Dilute 170cfu/ml of Sutherland bacterial solution ten times to 17cfu/ml, and inject the bacterial solution once a day with a dose of 1 ml each time.

　　 On the 9th day, after 9 injections of bacterial solution (total 9 ml, 153 Sutherland colonies), the mice developed anorexia, vomiting and low vitality.

　　 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 (total 15 ml, 255 Sutherland colonies), the first mouse died 7 hours later, and the second one died 11 hours later.

　　 After anatomy and pathological examination of the dead body of the mouse, the experimental body died mainly from the nerve infection caused by the bacteria.

　　 It seems that "Sutherland Bacteria" is not used arbitrarily. The arbitrary abuse of super large doses will cause unpredictable and 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 according to the tolerance ratio between humans and mice, 153 divided by 37.5 (the median value of the interval) was approximately equal to 4.

　　 mice weighing 20 grams (0.02 kg), ordinary human men weighing 75 kilograms, the weight ratio of the two is 1:3750, and the tolerance of Sutherland colonies for ordinary men 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 situation, 3400 Sutherland colonies can suppress 3 kinds of abilities. Then, 15000 Sutherland colonies can suppress 13 kinds of abilities. If you do a conservative reduction, you can get a 75 kg. Adult men can have about 10 abilities at the same time.

　　Through this Sutherland bacteria tolerance experiment, Todd finally got the following conclusions:

　　 A 75 kg man was used as a control.

　　1. The upper limit of the Sutherland bacteria that can be tolerated by humans is 15,000 colonies (this quantity level may cause pathological symptoms). If the density of Sutherland bacteria liquid is 170cfu/ml, the maximum injection volume is 88.25ml.

　　 2. Once humans have been injected with more than 15,000 Sutherland colonies, they will develop nerve infections caused by bacteria. The initial symptoms are anorexia and dullness, the mid-term symptoms are epilepsy, and the late symptoms are neuronal degeneration until death.

　　 Three, the upper limit of human ability to accommodate is 13 kinds, if it is safe, it is conservatively estimated to be 10 kinds.

　　 In a word, if a human is transformed into an "heir", he can carry up to 10 kinds of abilities. If this number is exceeded, there is a possibility of disease.

　　 After determining the upper limit of the abilities that the "Heir" can carry, the next step is to determine which abilities should be carried.

　　 Todd made a statistics. After repeated testing and screening, there are currently 18 kinds of effective and available abilities in the "Ability Library", which are divided into three categories according to the types of abilities.

　　 Elemental Attack System:

　　 "flaming breath", "frozen", "strong acid blood", "sonic shock", "weakness"

　　 Physical Strengthening Department:

　　 "Perspective", "Night Vision", "Eagle Eye", "Resistance to Pain", "Regeneration", "Rapid", "Skin Breathing", "Webbed Hands and Feet"

　　 deformed mimicry system:

　　 "Metal Skin", "Body Transformation", "Chameleon Disguise", "Stone Fist", "Blood Mark"

　　 What Todd needs to consider now is, from these 18 abilities, which abilities are extracted to inject into the 13 "heirs" headed by Huggins?

　　 The selected criteria are as follows:

　　 1. Try to choose abilities whose manifestations are not obvious. After all, the ability to be too public will expose the identity of the alien and attract attacks from the church and the world. Therefore, the abilities of the elemental attack system cannot be selected.

　　Second, it should adapt to the fighting style of the Knights. Considering that the surrounding terrain of Muxi Town is mostly plain, the group charge of heavy armored knights will be the main means of combat. Therefore, in the selection of abilities, more charge and protection abilities should be selected.

　　 Three, pay attention to the number of abilities, and leave room for the later stage. The upper limit of an "Heir" is 10 abilities, but if you load all 10 abilities now, once more outstanding abilities appear in the future, you will not be able to erase and replace them. After all, Todd still has There is no way to remove foreign abilities in the body.

　　After thinking about it again and again, Todd finally selected three alien abilities for the 13 "heirs". They were "regeneration", "resistance to pain", and "metal skin".

In addition to this team, Todd also intends to equip them with a scout-Edgar, in addition to the opponent's existing "fast", he intends to inject the "Night Vision" and "Eagle Eye" into the scouts. can.

　　 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.

　　 Hudgens and Edgar are not worried about him. What makes him a little embarrassed is the 12 former subordinates of Hudgens. Because these people are not heterogeneous, they are all normal people like fake replacements. Letting them undergo bacterial transformation is an order that is beyond the normal scope.

　　 What surprised Todd was that after 12 sergeants listened to him, they all said they could receive the injection immediately.

　　 After repeated confirmation by the priest, the sergeants still insisted on their opinions.

　　 Finally, these 14 people received the "heir"'s bacterial transformation within three days. Except for a sergeant who had a strong rejection reaction when he received the "Sutherland Bacteria", but with timely treatment, it was fortunately not a serious problem.

　　 At this point, including 1 (former) knight, 12 (former) sergeants, and 1 (Mengxin) scout, the first combat team of the Twilight Knights was formally established.

　　 After handling this matter, Todd instructed Huggins to start recruiting peasants and believers in Muxi Town. In peacetime, the peasants are mainly responsible for the management and operation of the teaching properties of the Knights; during the war, they are mainly responsible for the transportation of materials, and sometimes they are also responsible for cleaning the remnants and cleaning the battlefield. Believers are generally the basic military force of church institutions. They are composed of devout catechumens. Under the leadership of church knights, they carry out combat skills training and formation; in wars, they will follow the knights and sergeants. Behind them, as the military force of the third echelon of the Knights, they fought.

　　 After finishing these matters, the time has come to the end of September and the beginning of October in 1170. It has been less than two weeks since the Papal Council of the Grand Ecumenical Council and the official encyclical announcement of the Knights of the West.

In the morning of this day~lightnovelpub.net~ Todd was walking on the street in Muxi Town, watching Joe and the monks measuring the red line of the land and the distance between the houses, and discussing with the craftsmen headed by the old Aiden Street planning and architectural layout; Huggins and the sergeants led a group of believers composed of 68 catechumens to conduct basic formation training in the open space not far away; Alfonso was on the hills in the distance , Carrying out physical training hard with a big sword.

And Todd himself, according to the agreement, came to the table on the first floor of the hotel on the first day of the opening of the "Sisters Hotel" between Rachel and Karin. When thinking about what to eat, a figure stumbled in at the door.

　　 Todd raised his head and looked intently. It turned out to be a cute new scout with a panic-Edgar.

　　 "Cavalry! A lot of cavalry came up to the town!"

　　 Hearing what he said, Todd quickly put down the menu in his hand, stepped out of the store, walked to the square, and looked far away along the street. Using the power of "Eagle Eye", Todd clearly saw a dozen heavily armed silver ring knights rushing towards Muxi Town on the plain.

　　 When Todd saw this scene, the first thought in his mind was—Are these people crazy?

　　The army of the secular kingdom broke into the territory of the church without permission. Is it possible that someone is so arrogant that they are enemies of the entire church?

　　 When the team got closer, Todd saw something strange. The headed old knight with all white hair and beard, bloodstained, and a few arrows stuck in his armor, looked like Baron Cumberland, with a person sitting behind him. Todd tried his best to distinguish, that the man seemed to be a young woman in a luxurious court gown.

　　 When Todd could see who the woman was, he involuntarily took a breath.

　　 Queen Mary...
