"Black and white! I'm sorry! I just wanted to 'pump' some of your blood for research! ”

Liu Ye also smiled unusually kindly, but the hand he hid behind him quickly 'inserted' into the black and white body. Slowly pull the needle and 'draw' a tube of bright red blood into the needle.

The black and white whole body 'hair' exploded, looking at Liu Ye's tiger eyes 'revealed' a sad and angry gaze, he was bullied by Liu Ye so much, I want to tell the 'female' master to go!

"Don't be angry! It's just a little tiger blood, I'll give you more food tonight, and I'll make it up right away! Liu Ye smiled, feeling the anger of black and white, and slowly stepped back.

"Roar ......" The angry tiger roar came out of the black and white mouth, and the four creatures were immediately frightened to the ground on all fours and did not dare to move, the voice seemed to say that there is no need to add food, you are the most suitable.

As a result, the people of the capital city today are surprised to find that black and white, who have always been harmless to humans and animals, are frantically chasing their city lords.

"The city is really hard, not only to pay attention to the development of the metropolis, but also to accompany black and white to make games!" A few of the townspeople thought they were underground.

"I'm not making a game, who's going to save me!" Liu Ye only held the tiger blood in his hand in one hand, and shouted sadly in his heart.

Hei Bai chased three streets, and blocked Liu Ye at the 'door' of Huaxia Building for a morning, and finally under Feng Ruiyan's comfort, he barely lost his anger and left in a huff.

It seems that Liu Ye is not in any danger for the time being, but it will not be easy to drive black and white to do something for it in the future.

However, the tiger blood was obtained, and the study of the main brain began. With the experience of developing wolf 'sex' and 'stimulone' last time, this reagent was prepared within three days.

"There will be no side effects of this 'stimulone', but it is full of wolf 'sex' and 'stimulone' from the last time, and everyone only has one chance to 'shoot' this 'stimulone'! So you have to choose carefully! "The mastermind said this when he 'handed over' the 'stimulant' element to Liu Ye.

"That is to say, each of them can only choose one kind of 'excited' injection 'shot'!" Liu Ye caught the 'excited' element thrown by the main brain and asked.

"It's okay if you understand it that way!"

"Got it!"

The meaning of the mastermind is very clear, everyone only has one chance, once the wolf "sex" and "stimulant" hormone are chosen, they cannot choose the tiger "sex" and "stimulant" hormone.

"That's fine, but there is one more profession, now it's time to see if this 'stimulone' has the kind of effect that the main brain said!"

The experiment was successful, Liu Ye selected a citizen to 'shoot', and it quickly had an effect, unlike the last time the wolf 'excited' had such a reaction.

In front of the citizens who were injected with tiger "sex" creatures, the four mutated creatures all disappeared from their previous aggressive "sex" and were docile like lambs. Even when Liu Ye ordered the person to go over and 'touch' them, the other party did not have any resistance.

However, due to his nervousness, the black and white aura released by the citizen was so powerful that the four mutated creatures were too frightened to move, and they couldn't do it anymore.

Liu Ye, who discovered this phenomenon, ordered the person to release a trace of breath slightly. The townsfolk tried in disbelief, and sure enough, the four creatures were no longer too frightened to move, and could move around.

"The experiment was successful, and the amount of this pheromone can be controlled!" Seeing the scene in front of him, Liu Ye became excited.

The success of the experiment marked the formal establishment of the aquaculture industry in the metropolis, and all that remained was to gather manpower and increase the number of organisms.

According to the measurements, the amount of mutated biomass that citizens can influence is related to the level of their energy and energy, and the first layer of energy can control about ten mutated creatures, while the second layer of energy and energy have tripled, and the number of people in the third layer of energy has risen to hundreds.

But the problem is that even if the citizens who have reached the third level of energy are willing to come to breed, Liu Ye does not agree. People who can cultivate to the third level of Xuan Qi are all considered 'Jing' Ying, how can they be allowed to do this kind of work.

Anyway, there are a lot of idlers in the capital now, and Liu Yesuo's 'sex' locates the creatures of breeding cattle, sheep, chickens, and horses on the citizens on the first and second floors.

There are a lot of citizens on the first floor, and most of them are in a state of having nothing to do, and they are too energetic every day, and they don't do anything except 'make' their mother-in-law to scream.

Now is the right time to guide the 'essence' of these citizens who have nowhere to vent.

Although all four creatures have a certain amount of aggression, they are not difficult creatures to deal with in the wasteland. Liu Ye gave an order, and the four creatures around him were immediately looted.

The sweet potato hypnotic bomb developed by Liu Ye also came in handy, and hundreds of various creatures were placed in front of Liu Ye.

Forty five-metre-high iron fences were built and distributed to forty citizens who were 'sexual' in line with the aquaculture industry. Liu Ye ordered a certain share for them, Liu Ye gave them a subsidy if there was less, and they could digest Liu Ye by themselves.

Today's requirement is to survive as many creatures as possible, and to have as many babies as possible, and to produce as much 'milk' as possible.

Such a measure can be said to be very generous, but it is not without cost.

The price is that they have completely lost their lives with the Black Wind Bear and the Phantom Wolf, and their only mount may be the Benlei Horse they raised.

However, they may not regret it, becoming a Black Bear Guard and Phantom Wolf Guard is too demanding. These people know that with their qualifications, the chances are too slim. Rather than go on there, it's better to find another way out.

The choices of these people also inspire other citizens who are waiting. Slowly, the other professions provided by Liu Ye were gradually chosen, and they no longer stuck to the two professions of Phantom Wolf Guard and Black Bear Guard.

So far, the following professions have emerged in the metropolis:

The 'female' worker of garment and textile is a good profession that brings out the 'female' and 'sexual' to a bit, and at the same time solves the relationship between some men and 'women'.

Farmers, this profession is not demanding, as long as they are trained, they can be competent. It's just that the farmland that the capital can control is limited now, so the number of people it can accommodate is not much.

Hunters, almost every citizen of the city is a qualified hunter, but now there are people who specialize in hunting designated prey for a living.

Salt workers, most of the original citizens of Haiwei City are engaged in this work.

Kelp farmers have done a good job of gathering idle people in Haiwei City, and the danger has been minimized, but it still requires a certain amount of strength to be competent.

Biogas digester maintenance workers, with the development of the city, this type of work is expanding, in addition to maintaining the digester, they also have to collect human and animal manure in order to be able to maximize the use. In particular, these fermented manure is the best natural 'fertilizer'.

There are very few steelworkers in this part because of the high demand for skills, but Liu Ye is trying his best to increase the proportion of this type of work.

Medical staff, except for textile 'female' workers, the remaining 'female' and 'sexual' in the capital are all doing this profession, which is an indispensable occupation in the metropolis.

Guard: The basic defense force of the capital, the average strength is at the second level of the energy Xuanqi, the 'servant' guard rank.

Wind Troupe: Adapted from the Wind Thieves Regiment, Liu Ye also added some personnel from the original capital city and Haiwei City, with an average strength between the 'squire' guard rank and the knight rank.

Huisuke: The second in command of the army, mainly to help correct the thinking and style problems of soldiers.

Metropolitan Member: Associate profession, strict screening, but there must be a good future after entering, although there is no remuneration, but it ranks second in the metropolis.

Livestock farmers, the latest emerging profession, can provide a stable supply of 'meat' and eggs and 'milk' for the metropolis, and the future is bright.

At present, there are so many occupations in the capital and Haiwei combined, which can accommodate more than 4,500 people, which means that there is a limit of nearly 1,000 people, and the unemployment rate is as high as 10%.

According to the budgets of experts in the past, the stability of a society must be maintained at least 4% of the unemployment rate, but at present, the capital city is far exceeding this figure.

Now the capital city can remain stable, mainly because of the effect of Liu Ye's personal charm. But the charm is very unstable, it may remain for a lifetime, or it may disappear in an instant.

The human heart is very strange, so people must be allowed to do something and gain something, and this is the king of stability.

It's just that the potential of the capital city has been almost developed in Liu Ye's opinion, even if the capital city develops in the future, the current career structure will still not undergo major changes. It is only from the development of the capital city from the current agricultural civilization to the industrial civilization that a series of new occupations will emerge, but this development will take a long time.

For the time being, Liu Ye can only use the work of building roads and houses to temporarily fill the 1,000 idle population, and when the wind power plant in Cyclone Valley is rebuilt, it can accommodate several hundred people at that time.

The walls of Haiwei City were only temporarily repaired, and they just needed to be reinforced. Moreover, the scale of Haiwei City is quite different from that of the capital, and it is also possible to temporarily relocate a thousand people there for repair and reconstruction.

Especially the 'female' people in Haiwei City have an extra situation, and it just so happens that a bunch of bachelors also have a goal, and it's not bad to match each other or something in their spare time.

Of course, all pursuits must be carried out under the rules set by Liu Ye, and anyone who violates them will be punished mercilessly by Liu Ye.

One windmill after another was built, in fact, what Liu Ye hoped most was that the steel plant could increase manpower, and the production efficiency was too low. Unfortunately, the learning and training time for this type of work is very long, and it will take at least a month and a half for the next batch of new workers to be able to use it.

Liu Ye could only make up for it first, but fortunately, ten big windmills had already been built and could be used for preliminary tests.
