The five-year preparation plan was officially implemented, and Liu Ye's instructions to increase the quality training of the people were also put on the agenda.

In the entire metropolitan country, except for the regular army that maintains law and order on a daily basis, and the power positions that must be produced in some parts of the construction and scientific research, the rest of the people are scattered in the adjacent areas of their cities. Began to run 'waves' for food reserves.

At the same time, in order to meet Liu Ye's request, the city's citizens were required not to use any external force, but to rely on their own strength to obtain food.

In the past, the townspeople had no trouble getting food thanks to domesticated sulfuric acid dogs, and this way of obtaining food also made the self-confidence of the citizens unprecedentedly high.

Now an order has completely stripped them of their powerful cloak and re-revealed their true colors.

At this time, the citizens who had been hunted a little later or had never been proud of hunting pets slowly gained the upper hand in the new round of competition. With little or no help from their pets, they have been relying on their own efforts to get food.

This way has trained their strength very well, although the increase in energy and Xuan Qi is very small, but their survival skills in the wild are much higher.

"The way human beings evolved in the past relied too much on external forces and ignored their own evolution, so that while the human brain has made great progress in 5,000 years, the human body has not only not evolved, but has undergone a certain degeneration! I think that's why humanity fell so quickly into this field when the trouble came! ”

"The mistakes of humanity must not be repeated on us! From today until the end of the experiment, everyone should devote themselves to improving themselves, and this is the right way to evolve! ”

This is what Liu Ye said when the city lords were present, and after the heads of each city went back, they repeated it as it was, and the hunting methods of the people of the capital country also began to change.

In the past, the hunting method was to use the hunting pets in their hands as the main attacking force, and then they assisted from the side. But now it's the complete opposite, hunting pets has become an aid, and it's the humans themselves who really decide the success of the hunt.

From the former assistant to the current main force, although the change in hunting methods has led to a significant reduction in the efficiency of hunting, people feel a sense of excitement that they have never felt before.

Assisting in pet hunting and pet hunting to assist oneself, defeat mutant creatures to get food, and the feeling after success is completely different.

Whenever there is a success, the excitement in people's hearts is always much higher than the former, and most importantly, the more they go on such a hunt, the more they feel as if something is reviving and awakening.

This kind of thing makes them braver, more powerful, and more efficient in hunting.

This kind of thing was actually studied by humans before the war, and it has many names, but the most famous one is this one, and people call him:

Instinct!

In addition to the name instinct, people have other names, such as the subconscious, such as animal 'sex'......

However, according to the cultivation method of the Essence Qi, it is also called: Heart of the Beast!

No matter what the name is, in short, this kind of thing that has begun to awaken and revive has greatly improved people's strength. It didn't make any significant improvements in the energy Xuanqi, but people's combat skills, on-the-spot reactions, and willpower all improved significantly.

This kind of improvement is what Liu Ye wants most, in his opinion, the strength of the body is just a thin piece of paper relative to the strength of the heart. This kind of strength is only relative, only the inner strength is absolute, and it will be invincible at all times.

The current city's citizens are far from reaching the level that Liu Ye requires, but fortunately, they have finally started, and the direction is also correct, which has made Liu Ye very satisfied.

He believed that with the current state of the people's spirits, once the group attacked, the assembled spirit and morale of the people would be able to repel any enemy who was not strong-willed.

Of course, after the prey is hunted, it must be preserved, which requires large cold storage.

With the current level of science and technology in the metropolis, it is not very difficult to establish such a cold storage. Following Liu Ye's orders, cities began to build cold storages to preserve more and more food.

At the same time, the demand for electricity is becoming more and more tight. What was once considered to be an abundance of electricity is a joke in the face of a series of new facilities.

In desperation, Liu Ye had to implement the measures taken when there was a shortage of electricity in the capital city, and cut power every day to ensure the normal progress of daily production.

As the saying goes, it is easy to go from thrift to luxury, and it is difficult to go from luxury to thrift. When the people of Dadu have adapted to the life of electricity, they are suddenly faced with a life of lack of electricity, and they are really a little uncomfortable.

The darkness of the night without the light adds a lot of fear of the unknown.

Electricity has not existed for a very long time in the metropolitan country, and compared to the safety and comfort of electricity, the people are more likely to fight in the harsh environment of the wasteland.

After a period of discomfort, the people gradually returned to the past, and they no longer complained, and devoted themselves to production and construction activities.

The reserve of food does not depend solely on hunting, to be honest, the proportion of food that can be brought by hunting is not very high, and the citizens of most metropolitan countries are currently able to fill their stomachs, and the most important thing is to rely on planting and breeding.

The yield of various crops improved by the ancient ocean is surprisingly high, and the annual harvest alone is enough to feed every citizen, and there are still remnants.

After Liu Ye put forward higher requirements, Gu Yang began a new round of research. This guy didn't know where to get a copy of the agricultural planting manual, and he really 'made' a good crop by going back and forth in the above way.

Perhaps the variation of the wasteland, and the abundance of water in the nearby dredging canal, combined with the abundance of water in the nearby dredging channels, led to an astonishing increase in the food crop the following year.

This time, Gu Yang decided to build on the previous foundation and completely break the popular technology in the book - hybrid 'crossing' rice.

If this technology can be broken, then the grain reserves required by Liu Ye can be completed in advance.

This is true for farming, and it is similar for aquaculture.

Gu Yang does have a great talent in agriculture, he used to be a salt worker, but he was indeed buried. The mutated cattle, sheep, chickens, and horses in the breeding industry have been tamed by him, and he also selects the high-quality varieties that produce more 'meat' and have good 'meat' quality, so as to increase the proportion of 'meat'.

In the last days, 'meat' is the most important food. Without 'meat', there is simply not enough calories to provide people to fight mutated creatures.

However, if these foods are simply preserved in their original form, they will greatly 'waste' energy, so people have come up with more efficient ways to preserve them.

These methods were obtained from the books left in the various cities, and they were all reprocessed.

Through drying and refining, the grain is 'made' into various flours on a mill. This food processing production line designed by Jiaozi is supposed to be the largest known factory, and the considerable equipment in it is still directly using the 'medicine' equipment of Kek Lok Tang.

Crushing grain to refine flour is very similar to the physical process of making 'medicine' in Jile Tang, and after two days and two nights of research, Jiaozi and Gu Yang studied it for two days and two nights, and then finalized the plan and began to modify it.

The completion of this production line has greatly improved the efficiency of food use and storage, and people have known for the first time that there is still this way to eat food.

Flour grains can be stored in a dry environment for a longer period of time, take up less space, and the taste of these foods adds a unique flavor compared to the original.

At this time, the rails and trains once again played an important role. Every day, the train whines and whizzes past the tracks, loaded with all kinds of crops for use in the food processing factories of Jodo City, where they are processed and transported to the grain storage sites in various places.

Of course, although this kind of transportation is very efficient, it is very costly. Liu Ye has ordered Dadu City, Haiwei City and other places with a relatively high industrialization base to start building their own food processing plants, directly processing them according to the principle of proximity, and then storing them on the spot, so that the freshness of food can also be preserved well.

Due to the shortage of electricity, Liu Ye had to allocate funds again to distribute materials for the re-construction of the power plant. Drawing on previous experience, Liu Ye found that many small power plants could not provide as much electricity as one large power plant, and the cost seemed small, but in fact it was still more than building a large power plant.

Therefore, Liu Ye has given up the construction of the biogas battery, and completely 'handed over' it to the private sector, the biogas battery is simple in situ, the cost is not large, and the private sector can quickly start construction after training.

He is now focusing mainly on thermal power, hydro and wind power, which are the three energy sources that best address the current electricity demand. Inspired by Jin Yi, he also began to set his sights on geothermal energy, which, if developed well, could also become the fourth largest energy source in the metropolis.
