Today's results are not very good, and even with the help of black soil to absorb energy, it does not allow the big-headed ants to achieve the winter activity ability of paver ants. However, the protagonist is not discouraged, and he has expected it for a long time.

The next day, the protagonist changes his experimental methods again. This was not an impromptu idea, but was planned on the first day. Since the first day was not as good as it could be, this alternative is ready to go.

Today, the protagonist still chooses ten new worker ants and soldier ants to participate in the experiment, and the big-headed ants who participated in the experiment two days ago have a chance to rest. This avoids the physical exhaustion caused by continuous participation in the experiment.

The ants who participated in the experiment, as they did yesterday, did not crawl out of the hole directly.

After sunrise, the protagonist first carries a large clay pot down to the ground and digs up an entire pot of black clay clay grains.

The protagonist then carries the black soil back to the nest, where a worker ant hands the protagonist a "broom" made of large clusters of twine, and another worker comes with a clay pot of sealed ant glue.

The protagonist opens the mud-sealed ant glue, and since the ants do not reproduce in winter, there are no larvae to provide ant glue. These ant glue are sealed in the autumn for temporary needs, and the ant glue has not yet solidified.

The protagonist uses a twine broom as a brush, dipped in ant glue and quickly brushes it onto the subject's exoskeleton carapace, avoiding sensitive locations such as stomata and eyes.

Then the worker ants who assisted next to them immediately raised the black soil particles onto the test subject, and soon, the soldier ant, which was still yellow, became as black as if it had just been drilled out of a small coal kiln.

After all ten test subjects have done the same, the protagonist takes them outdoors to continue the experiment.

Every half hour, the subject will move a little. Today, the subjects are doing well, and after an hour in the sun, they are able to move more freely. Although it can't be said to be the same as in summer, it doesn't have much effect, just like the feeling of walking in a thick cotton jacket in winter.

Moreover, from 10 a.m. to 4 p.m., they can move freely as long as they are under the sun, and their activity time is much longer than before. It was only after four o'clock that they had to return to the nest due to the dimming of the sun.

Because there is no "antifreeze protein" in the body, the performance of the big-headed ants coated with black soil is still not as good as that of the paving ants, but it is enough to meet the needs of some basic field activities and work, and it can be regarded as meeting the requirements of the protagonist.

Although the protagonist does not fully understand the reason for the gap with the paving ant barbarians, he has also gained a lot. Such a small group of ants that can be active in the wild in winter can already do a lot of work.

Over the next few days, the protagonist selects a group of strong ants and asks them to brush up on the black soil and join the army of winter wilderness survival training.

These ants who have been trained are all members of the "Waterfront City" garrison legion, that is, the garrison of the original "Waterfront City". Because these test subjects are to be used as force workers in the future, there is no need to use elite troops. In addition, the Legion of the Divine Envoy King is carefully cultivated by the protagonist, and the protagonist can't bear to let them engage in such a slightly dangerous experiment.

The number of big-headed ants involved in the training soon reached 200, and due to the lack of ant glue, the scale could no longer be expanded. Fortunately, as long as the ants who have been coated with black soil pay attention, the black soil will not peel off in a short time. The remaining cans of ant glue are used as the last backup.

The training was relatively successful, and the vast majority of strong and healthy worker ants and soldier ants were led by the protagonist, barely adapted to the winter wild, as long as the sun was sufficient, and the ants participating in the training did not come into contact with deadly substances, then there was no danger to life.

Due to their unfamiliarity with the wild environment, a small number of big-headed ants accidentally got contaminated with snow particles, and the melted snow particles quickly took away a lot of heat from their bodies, causing freezing.

If these unfortunate eggs happen to be in the shadows, and there is no sunlight to save them in time, they will soon freeze to death. This attrition soon took place several times, and the protagonist had to ask all the participating ants to act collectively in groups of at least three ants, and always pay attention to whether their companions were contaminated with substances that caused their body temperature to drop.

After a few days of training, the weather began to deteriorate and the protagonist had to interrupt his training.

Next, a blizzard quickly took over the sun's dominance, this time with much more rapid snowfall than the previous one, with a thick layer of snow quickly covering the entire land.

Even the entrance to "Waterfront City" has snowflakes drifting in, and the protagonist has to go into battle himself and temporarily block the entrance and exit with some filler. Only the vent of the combustion chamber is left as the only outlet for the external exchange of gases.

On days when the wind and snow are raging, although the temperature in the nest is maintained well, the air is very stuffy. This is due to the fact that there is only one vent and the air cannot be convection, resulting in a decrease in oxygen content.

Some of the frail ants are unwell, and the protagonist has to ask everyone to try not to move in order to save oxygen. The protagonist also opens the seal of the entrance and exit hole from time to time, allowing the air to circulate occasionally.

This blizzard wasn't entirely bad, at least not because the Paving Ant Barbarian Army couldn't go out in this weather. If they were going to attack the other nests, they would have to stop their attacks now, giving the defenders a chance to breathe if they hadn't been breached yet.

Even though it was snowy outside, the rope weaving work in the "Waterfront City" was not interrupted. The work is no longer required for the guidance of the protagonist, and every moment this thick hemp rope is being extended.

By the time the blizzard subsided three days later, the hemp rope was halfway finished.

The protagonist leaves the lair today and steps outdoors for the first time since the snowstorm fell.

Even all the branches outside the cave were covered with snow, and the cracks in the bark of the trees were also covered with snow. The whole world is already a snow-white world, and only a few trees and boulders can survive being completely covered by thick snow.

The protagonist shook his head, such a big snow, such a thick layer of snow, it seems that it will not melt in the short term. With this thickness of snow, even paving ants do not dare to act on the snow layer wantonly, and if they are not careful, they will be killed by the melting snow.

But the protagonist can't do nothing, just wait for the snow to melt, then maybe wait until the beginning of spring. The winter field training of the big-headed ants has not yet been completed, and after the hemp rope is completed, it is necessary to tie the hemp rope to both banks while the ice is strong to form a suspended rope bridge.

The protagonist looks at the snow and decides to organize the ants to go out, combine training and work, and make preparations for the construction of the suspended rope bridge as soon as possible.
