Let the alien assistants who work together on "Discoverer" take their place, and Todd himself assumes the role of "Search Heir".

After the sample of the spring water was stained, it was put into the observation chamber. After the "wind pressure" vacuum treatment, Reicher fine-tuned the position of "Tesla" under Todd's instructions and slowly increased the voltage intensity. The "concentrated" alien species collected and amplified the photons that hit the electron beam and burned them onto the white paper.

Todd looked at the blank paper that was last imaged and could barely see the general situation in the sample, but it was still too vague.

After trying it for more than a dozen times, Todd picked one that looked the clearest.

The paper shows that a strange thing is attached to the huge bacterial surface. It looks a bit like a pothole-burning surface of the moon, and a "space lunar module" is placed.

Looking at this thing with four legs and a sphere body, Todd became more and more familiar with it the more he looked at it. This thing seemed to be the most common virus in his previous life - "bacterial phage".

Speaking of bacteriophage, it is the most common and most diverse virus in the microscopic world in the previous life. In no exaggeration, a liter of water may contain trillions of bacteriophages, with more than all the stars in the universe combined. No wonder some biologists would say that compared to the world of viruses, the universe is just a speck of dust.

The principle of phage lysing bacteria is summarized in a few simple sentences. The first step is "Login in the bacteria", and the tail of the phage is attached to the cell wall of the bacteria; the second step is "spawning", and the phage pierces the tail axis into the cell wall, like a syringe, injecting DNA into the bacteria; the third step is "incubation", the phage will use the "nutrients" in the bacterial cells to replicate the DNA and proteins of the progeny phage, and finally, like a heteromorphic eruption from the host body, the daughter eats all the bacteria and drills out in large quantities to find the next victim.

But generally speaking, as a virus phage, it is different from broad-spectrum antibiotics such as penicillin. It can only cleave one bacteria in a single phage, which sounds a bit useless, but compared with antibiotics, they have many benefits.

for example:

1. Low hazard. Most phages will only attack specific bacteria and will not harm normal cells and beneficial bacteria in the human body.

2. Less antibodies. Bacteria are difficult to produce antibodies to phages, but they have a considerable chance of developing immunity against antibiotics and may be converted into super bacteria.

3. No residue. Phages are host-dependent and will die as the bacterial host disappears, and will not remain in the human body to trigger a series of toxic reactions.

4. Easy to use. The development and development of phages is short and the cost is low. Bacterial fragments can be purified and isolated by simple centrifugation. They can be stored for a long time at room temperature, and are convenient for transportation and application.

Of course, besides this, phages have many other uses, so I will not introduce them one by one here.

After figuring out the truth that spring water can "heal" xenotypes, Todd began to further study these phages, but found two interesting things: most of the phages in spring water only target xenotype bacteria and have no effect on other bacteria; almost every xenotype bacteria in the Muxi Town superpower library can find specific natural enemies of phages in spring water.

There is one most important thing.

The bacteriophage in the spring water is ineffective against "Sustherland Archae".

Todd was incredible at first, but after repeated experiments, he verified the result. When the phage landed on the "Sustherland Archae", after a period of time, it would lose its vitality and eventually fail. The specific reason was that it could not be found with this original electron microscope.

In short, bacteriophages can "cure" xenotypes, but are ineffective against "successors".

Todd finally breathed a sigh of relief after getting this result.

Next, toxicity tests are performed on spring water.

Todd took five experimental mice into a group and fed spring water according to the tolerance ratio. After a week of observation, he found that the five mice had different degrees of high fever, erythema and dehydration, which were exactly the same symptoms as those dead children in Valkyrie villages.

After dissection and tests, Todd finally found the crux of the problem.

Although most of this spring water containing high-density phage viruses is harmless, a small part of it is toxic. The latter destroys the immune system of the experiment and causes concurrent infections caused by low immune function. Especially for those babies, their bodies have not yet developed and their immune function is not complete. In addition, villages lacking food and water sources, feeding them with this spring water is like pouring chronic poisons on the babies every day.

As for those Valkyrie, why did they not show any symptoms of infection?

According to Todd's speculation, they should have obtained a large amount of "Sustherland Archae" from some channel and stored it in their bodies. When the phage invades, the Archae became a barrier to their bodies and saved their lives.

Upon learning of this result, Todd immediately found Huggins and asked him to send his subordinates immediately to rush to Lizard Island to find Valkyrie as quickly as possible, telling them to stop using the village's spring water immediately and use other fresh water sources instead.

As soon as Huggins left, Cumberland came to find him.

The old knight was wearing military uniform. The first thing he said when he saw Todd was: "General Commander, do you have time?"

The latter thought that the experiment on spring water had come to an end, so he planned to hear what Cumberland wanted to say.

The two came to the head of the Knights headquarters. Cumberland had no intention of taking the seat at all, and said straight to the point: "General Commander, this time the army of the Beishi Mine is planned to set off in three days. I hope you will be the commander."

Todd said in surprise: "What? Do you have anything else? Can't participate in this battle?"

The old knight shook his head: "I will participate in this expedition..."

"Then why do I need to take the position of commander?"

Cumberland looked a little angry between his eyebrows: "General Commander, please forgive me for being too talkative, you have too much time in the laboratory!"

Todd was completely confused when he heard Cumberland's sudden stupid words.

Cumberland looked at the "umbrella" flag in the chief's office and said in a gentle tone: "In the past, you were the chief commander of the Knights of Musi and the spiritual leader of the entire Knights. You can indeed hand over the war to the priests and the commanders of the legion. But in the future, everything will be different. If we successfully occupy the North Stone Mine this time, it means that the "Knights of Musi" will be officially established, and you will bear the dual responsibilities of the leader of the Knights of Musi and the secular king on your shoulders."

Cumberland paused and turned his eyes to Todd: "A lamb who bows his head and eats grass in the sheep pen will never be able to lead a group of hungry wolves! Lord Todd, believe me, as a king, you need to walk out of that damn "Tower of Heaven" and let your people and your soldiers see your victorious posture on the battlefield!"
