Three days later, Rachel walked into Todd's expository hall with a thick note.

"There are currently 79 xenomorph refugees in Dusk Town, and I've compiled everyone's introductions and listed them here......"

took the record book from the woman's hand, and flipped through the records of each heterogene, including name, age, place of birth, heterogeneous ability, experience profile, neighborhood reputation, etc., everything. With a little surprise and admiration, Todd glanced up at the organizer, then turned his attention to the paper.

After some screening, Todd finally singled out a male xenomorph.

"Randall Quincy, male, from Lone Rock, 19 years old, unmarried. Once a hunter in the mountains, he fought in the war against the infidels in the south to defend his homeland, and was diagnosed as a xenomorph when he was treated, and then escaped from the army and the church, and his only relative, his mother, died on the way. According to the testimonies of neighbors with whom he spends his day-to-day lives, he is low-key and unremarkable, but helpful.

Xenomorph ability: Regeneration. With the exception of fatal wounds to the head and heart, any wound can grow new flesh and heal in varying lengths depending on the size and depth of the wound. 』

"Are you sure it's this one?" said Richel, picking up the introduction and reading it carefully.

Todd thought for a while: "You can't be in such a hurry to decide, just by relying on these introductions, you can't judge a person's good or bad, good or evil. ”

Suddenly remembering something, he said to Reichel in a mocking tone: "I now kind of understand why you tested me so many times in the first place. ”

The woman smiled, not intending to continue the topic at all, and tapped her finger on the paper and asked, "If you are sure that it is this person, what are you going to do?"

"I've heard lately that the town of Twilight is becoming more and more populated by merchants and travelers, and that robbers and bandits are eyeing it. I intend to sponsor this xenomorph by providing him with food, lodging, equipment, and payment, so that he can protect passers-by for free. In this way, to improve the ......"

"To raise the profile of the xenos in the minds of the populace?" Rachel helped him finish his last sentence without waiting for Todd to finish.

Todd nodded.

The woman fell silent, staring into the priest's eyes, which made the latter a little uncomfortable, and asked, "What's the matter?"

"No, no problems. Rachel propped her arms on the edge of the table and brushed her hair around her ear: "Master Chief, I heard that you are only fifteen years old this year......

"Huh?"

"Why don't I look like anything like that?"

Toddeton, stiffened.

Rachel covered her mouth and chuckled, shaking the paper in her hand, and she added, "Leave it to me about testing Mr. Randall." Up to a week, I'll tell you if he's the guy we're looking for. ”

Looking at the xenomorph introductions scattered on the table, Todd suddenly called out to the nuns who were about to leave: "Rachel, I want you to send these xenomorph refugees here in batches, I want to do a 'medical examination' for them." ”

The woman was stunned and repeated the strange word: "Physical examination?"

Todd touched the introduction of the "Xenomorph Ability" column on the paper with his finger, and said again: "That's right, physical examination." ”

————————————

Pulling the needle of the syringe from the arm of the young woman in front of him, Todd pressed a sterile cotton ball against the wound and said to her, "It's okay, after holding the wound for three minutes, you can remove the cotton ball." Also, take this ......"

He handed a small bag of copper coins into the woman's hand.

The woman was dressed in rags, looking at the priest in front of her, timid and afraid, and finally mustered up the courage to ask, "Holy Son, have we alien species been forgotten by the Heavenly Father?"

Todd carefully pushed the blood from the syringe into a glass tube and stored it in a preservation box. Hearing this, he turned his head to look at this alien refugee who had gone through vicissitudes of life, and said gently: "Heavenly Father never abandons any believer, remember that the key is whether your faith is strong or not. These afflictions are the trials of the Holy Spirit to the xenognes, do not shake your faith. ”

The woman gave a grateful look, nodded, and stood up and saluted Todd.

Looking at the other party's distant figure, Todd picked up the silver cross on his chest, looked at the holy book engraved on it, and sighed deeply.

Returning to his lab building with the latest batch of blood samples, Todd looked at the dozens of petri dishes on the table, each marked with various abilities in Latin.

"Regeneration", "Pain Resistance", "Metal Armor", "Flame Breath", "Night Vision", "Strong Acid Blood", "Sonic Shock", ......

There are about twenty of them, and Todd has given them an interesting name.

"Ability Library".

For him, the biggest problem now is how to preserve these abnormal bacteria. On the one hand, it is necessary to maintain the activity of bacteria so that they do not die, and on the other hand, it is necessary to ensure that there is no "bacterial contamination" to avoid the mutation of genetic traits.

In the past and modern society, the best way is "freeze-dried and preserved". That is, the microorganisms are first frozen, and then the water is removed by sublimation under reduced pressure. When the bacteria lose most of their water, the physiological activities of the cells cease and they are able to sustain their lives for a long time.

Taking a step back, you can also use the "liquid paraffin overlay preservation method", which is to cover the medium with sterilized liquid paraffin for low-temperature refrigeration. This method is simple and does not require special equipment, has a wide range of applications, and has a long storage time (several years or even more than ten years), but the liquid paraffin used is of high quality and needs to be autoclaved several times.

But the problem is that under the conditions of the Middle Ages, there were no high-purification separation instruments, no autoclaves, no microbial freezers, no liquid nitrogen bottles, and not even electricity. Naturally, these two methods simply cannot be carried out.

In this way, Todd plans to use the "subculture preservation method" and the "suspension preservation method".

The former is the oldest and most basic method of microbial preservation, and the general method is to set the culture temperature slightly lower than the optimal temperature for growth, and then adjust the concentration of the culture medium moderately, and transplant all bacteria every two days. This method has the advantage of being ready for bacteria, but it has the disadvantage of being cumbersome and prone to contamination.

The "suspension preservation method" is mainly aimed at non-aerobic bacteria, which are suspended in distilled water, sugar solution or phosphoric acid according to the characteristics of the bacteria to maintain their properties, and can be stored at room temperature for several years if stored properly.

It took almost ten days, and Todd was able to get all the bacteria to work. Looking at the full petri dishes and suspensions on the shelf, he could finally breathe a sigh of relief, and there was only one thought in his heart.

The prototype of the "Ability Library" is finally completed, although there are only more than 20 kinds of abilities now, but just like the library, with the research and discovery of abilities, this microbial warehouse will eventually become bigger and better, and maybe one day, after discovering the hidden secrets of the ability microorganisms, it can even be improved or even artificially synthesized into more powerful abilities.

A knock at the door interrupted his train of thought.

Closing the door to the back room, Todd walked to the door of the laboratory, opened it, and Reicher shook a stack of papers in his hand, and said with a smile: "Master Chief, the test results for Mr. Randall have come out, do you want to hear about it?"

Todd, who was standing at the door, turned his body sideways, got out of the way, and said, "Come in and talk about it." ”

Surprised, Rachel raised her eyebrows, lifted the hem of the wide nun's robe with one hand, and walked into the laboratory. Looking at the complex equipment and colorful solvents in the room, the woman sighed a little: "This is the first time I have been allowed to enter here. ”

Todd brought a chair, dusted it with a dry cloth, and placed it in the middle of the lab.

Rachel watched his every move, and for some reason suddenly remembered the relief party. The half-grown boy in front of him, in the same attire, preferred to curl up in the recliner in order not to rudely stretch his feet towards himself.

Seeing that the woman was in place, her eyes out of focus, Todd had no choice but to signal her to sit down.

"Tell me, did our Mr. Randall pass the test, and is he suitable for the role of xenohero?"

Rachel handed the paper in his hand to Todd's hand, held his chin in one hand, and said with some uncertainty: "It can be said that he passed, or it can be said that he did not pass......"

Todd withdrew his gaze from the paper and looked up at the woman, his face full of puzzlement: "Why do you say that?"

"There is no doubt that he has a strong sense of justice, and in the face of evil and injustice, he has never considered personal gains and losses and the safety of his life, and he will stand up every time......"

Listening to Reichel's words, Todd became more and more strange: "Isn't this very much in line with our requirements?"

The woman rolled up the cross on her chest with her fingers and looked to the side: "But his fighting style and fighting consciousness are unacceptable." It was a way of fighting with your life, never caring about the enemy's sword or wounds. During one test, my man was forced to nearly pierce Mr. Randall's heart by this deadly play. As far as I am concerned, it is more like a pursuit of self-destruction than a fight......"

Todd flipped through the "test report" compiled by the woman, and the more he looked at it, the more frightened he became. In order to save an "old couple" who happened to encounter a "robber", this guy is like a madman in battle, facing six enemies, he actually lifts his sword. He was stabbed and cut out of countless wounds on his body, but he still did not flinch until he fell to the ground without strength.

"I want to meet him. ”

Hearing this, Rachel glanced meaningfully at Todd and asked, "In what capacity do you plan to meet Mr. Randall?"

Todd put down the paper, looked at the woman and smiled, "Miss Richel, there is a priest who wants to show the way to the lost lamb. ”
