"The current Jianghu sect still has this rule...... Excuse me. ”

Xiang Shan's plain words set off waves in Cui Yu's heart.

He remembered that the elders of the sect once said that the rules of the rivers and lakes are not immutable.

In the distant past, when the rivers and lakes were just born, there was no "sect".

It's just that some people from specific regions spontaneously gather and set up organizations in order to hold together.

Then this organization expands in the form of a "magnetic chain".

In the end, it is possible that thirty percent of the core members of a sect will gather in a specific area, and then seventy percent of the members will be all over the world.

It is even possible that the head is on Mars and Venus, and the disciples are on Earth and Jupiter.

After that, those grassroots chivalrous men gradually summed up their own rules.

However, these rules are meaningless to a few celebrities.

They have lived from the time when the rivers and lakes were born to the present, and they may not fully agree with the current rules of the rivers and lakes. And the long years have allowed these knights to have unimaginable accumulation.

Although in accordance with the spirit of sharing, they have made everything they have learned as public as possible and stored it in the form of blockchain, but even the new geniuses cannot catch up with their century-old accumulation.

For these heroes, the "rules of the rivers and lakes" are not so important.

He had no choice but to smile and said, "If the seniors want to ask, I should have known everything, but ...... Actually, I don't know. ”

"Oh? Why? ”

"The culture tank that preserves the strains is kept by the elders of the gate......"

Xiang Shan thought for a moment: "You really don't know, do you?" ”

Cui Ji nodded.

Xiang Shan said: "So in your opinion, 'Huandanase' and 'Preservation Virus' are both very valuable resources?" ”

Cui Ji nodded.

Xiang Shan pondered for a moment: "To be honest, I don't understand very much, you have the conditions for production, right?" ”

"What?"

"In fact, Dan enzyme should be a cabbage price thing......"

"What is cabbage? It sounds like a plant. ”

"I mean, it's supposed to be a very cheap thing." Xiang Shan changed his words: "In terms of cost, if the cost of a chip is exchanged for Dan enzyme, the enzyme obtained is enough for a person to cultivate Turing from the beginning." ”

An organic matter that can be made by living organisms should actually be very cheap.

It is a very mature technical product. It can spontaneously synthesize the enzyme. As long as it is alive, it will excrete the enzyme in a steady stream.

The only raw materials needed are sugars.

In other words, as long as there are bacteria and starch, there is a steady stream of antidanase.

Yeast has a tenacious vitality and can be seen everywhere in nature. Its tenacious vitality and low cultivation cost also make it the most common eukaryotic recipient cell in genetic engineering laboratories.

The biggest cost of this technology lies in the R&D stage.

In other words, as long as you develop it, you only need to consume some starch, and you can easily scale up.

If you want to maintain high production efficiency, you need industrial equipment.

"In a sense, that's true." Cui Ji smiled bitterly: "In fact, in some areas, knights can still easily get things like Huandan. But...... It is difficult to ensure the simultaneous transportation of activity. ”

Xiang Shan nodded. Enzymes are very fragile things that deteriorate quickly after leaving the organism.

In this era, there is a lack of stable and effective transportation channels - at least there will be no chivalry.

Even if a certain sect can really be produced, it is extremely difficult to send it to the disciples.

"What's more, this kind of thing seems to be set to degenerate." Cui Ji said: "There are many knights who will try to steal the fungus from the government. However, bacteria are also things that degenerate. After one year of propagation, the efficiency of the bacteria in producing the enzyme will drop to one-tenth. ”

"The problem of the 'Divine Virus' is similar. It's too unstable. If you rob the furnace fungus and isolate the virus after three months of reproduction, then there is a considerable probability of adverse reactions. ”

"I see." Xiang Shan nodded.

Species degradation. This is a common tool used by biotech capital.

Crops of good seed can effectively help people get out of famine. Theoretically speaking, after the birth of a good seed, it can rely on the cycle of "seeds grow plants, plants produce seeds" to expand and spread all over the world within a few generations.

But the problem is that developers don't make money this way.

So, a lot of agricultural giants, they sell seeds, they don't produce seeds, or they don't produce seeds that germinate/can't grow high-yielding crops.

But there's a catch.

Xiang Shan remembers this technique.

In other words, it's a technology that existed in the old generation – most likely developed as part of Xiangshan's "big plan."

When this technology was born, it may not have yet appeared in the official system of "civilized patrons".

There should be a small number of strains in the world that do not degrade easily.

And a mature virus tool should also allow the knight to make a small number of strains by himself.

- No, wait......

If in nature, the vast majority of pathogens die out because of the overall changes in the biosphere......

In addition to the virus reservoir, there should be very few active viruses.

For example, simian vacuolar virus 40 (SV40 for short), a simple virus with only seven gene segments, was used by human scientists to insert foreign gene fragments into cells. SV40 can infect apes and humans, and has a certain chance of inducing tumors. But with the advent of baseline human modification surgery, humans are no longer infected by the virus. At this time, if the apes become extinct, then SV40 can only exist in the virus reservoir.

The same goes for all other viruses that can be used in GM technology.

As far as Xiang Shan knows, as long as you have collected a full set of viruses, enzymes and target gene fragments, transgenic genes are as easy as stir-frying.

After humans cracked the logic of the enzyme system, biochemical technology became something like this.

As the saying goes, it is difficult for a good woman to cook without rice. But the situation faced by the knights now may not be as simple as "cooking without rice".

They don't even have a pot or anything.

"The combination of resource monopoly, knowledge monopoly and lack of transportation channels can produce this effect."

Xiang Shan nodded and said, "In other words, in your opinion, these resources are not easy to obtain in a sense, so you feel pessimistic?" ”

Cui Yu nodded: "Half and half." Even if I have enough Dan enzymes...... But do I really dare to degenerate my existing neural circuits and practice again? ”

"I see. I didn't really understand this layer at first, which is why I thought it was strange. Why are you so depressed? This kind of brain damage, which has little to no mental impact, was easy to treat hundreds of years ago. ”

Cui Yu lowered his head: "It's really ...... Let the seniors laugh. Actually, I understand the truth...... It's just that...... Just ......"

"Crying for what?" Xiang Shan said: "I'm not your master, and I haven't blamed you for anything." ”

"My predecessors gave me precious medicine, and in the morning I was asked to observe the little girl's surgery to wake me up, and they also came here to enlighten me that there is still a lot of hope, but I ...... I...... I'm still so unhelpful. Cui Ji said sadly: "I am really ashamed of my predecessors." ”

"I'll you, what's the matter with you?" Xiang Shan sighed: "I'm just here to ask a question, don't make up too much for yourself." ”

"The most important thing about your illness is heart disease. Most of the martial arts that have been cultivated since the beginning have been lost at once, and within the known range, it seems that it is not very easy to treat. Isn't it normal for a person to lose control of their emotions in such a situation? It's just a moment of emotional out-of-control. I don't think you even have to avoid the crowd, you can cry whenever you want. But after crying, we still have to get down to business. ”

"The lessons of the predecessors are ......," Cui said, "It's just that I've been working hard for this since I was a child." All of a sudden...... Alas. ”

"Ready, ready. Rest for a few more hours and I'll be able to hook you up your spine. ”

Xiang Shan left this sentence and turned away.

The next day, Cui Ji connected his spine.

For days, he had to shield the nerve signals in his spine and manipulate the prosthesis in remote mode.

But as long as the wound heals and the nerves reconnect, he can better control the prosthesis.

And Yuki received a new makeover.

Xiang Shan removed almost all of the remaining internal organs of his disciple, and then replaced the muscles attached to his spine with the part of the prosthetic body.

At the same time, most of the "Dragon's Breath" was unloaded.

Yuki is already less and less in need of oxygen.

These surgeries, along with subsequent recuperation, took another four days.

After the fourth day, Xiang Shan and his party set out on the road again.

This time there were three cars on the road. In addition to the "donkey" and "mule", Xiangshan also has a fully automatic vehicle called "camel". The vehicle was completely unaware of the passengers' ride and was crammed with supplies.

They galloped all night across the land.

At the dawn of the day, a dazzling spot of light appeared on the horizon.

Songying City is already in sight.

At this distance, the guards are already quite tight, and there may even be a martial artist optical observation around the perimeter to be on guard.

So Xiang Shan stopped the car and took some weapons.

At this time, the "mule", a vehicle assembled at the base of the forklift regiment, played its role. With a quick swing of its shovel, it shoveled out two shallow pits half a kilometer apart and buried the "donkey" and "camel" shallowly.

Then the group of people held weapons and carried a small amount of supplies with them, and touched in the direction of Songying City.

After walking more than ten kilometers, Xiang Shan saw the city of this era for the first time.
