Douluo see you soon

The Furnace of Eternal Fire and the ice race living in it soon became famous, but the noise they made this time was actually a bit big. A huge ball of solidified magma with a diameter of ten kilometers. Such a big thing, you can't even observe it.

All difficult.

The Kingdom of Mor was immediately frightened. They were not the ones being attacked. Obviously, these people were rational and only retaliated against the kingdom that launched the attack. If they didn’t have the guts to go up and cause trouble for others at this time, then they would be unlucky.

It must be them.

This was a crushing battle, so the infected won a decisive victory without showing much high-end power.

And they also know very well that the underground people's war potential is actually extremely huge. If it puts huge pressure on them and makes them feel too threatened, then it is likely that they will unite and attack in groups.

At that time, it will not be settled by one or two super weapons.

The deterrence displayed now is just right. While calming down the neighboring countries, it is not asking for help out of excessive fear. After all, this group of people is abnormally low in temperature and is a strange race that is good at using low temperature attacks.

It has not shown any clear intention to expand.

In fact, their activities create a lot of energy for the underground people.

Under the deterrence of the previous terrifying frozen realm, the two sides reached a brief peace. This delicate balance could be broken at any time, but it gave the infection such time. It was an important time to accumulate energy and develop technology.

At the moment, their power is far from enough to declare war on the entire underground world. After all, what they are facing is not one or two kingdoms, but an entire group of creatures all over the underground. But with the development and advancement of technology, the result will not be certain.

After the underground friction briefly subsided, the infected once again entered a stage of rapid development, while the imperial army besieging the infected fell into anxiety.

The huge military expenditures to maintain the city walls and troops have given the imperial military a headache. In addition, the infected seem to be quite peaceful at present. In addition to sticking to the underground city they call Sylva, they just climb on the ground and plant grass everywhere.

.

It is literally planting grass. It is a strange purple plant that grows very fast and can be harvested in a day or two.

The Empire also obtained some samples of this grass, but the analysis results showed that the ingredients were almost the same as those of ordinary weeds. The only difference was that it did not perform photosynthesis. To be precise, it did not use chlorophyll for photosynthesis.

The biological development process of Douluo Continent has been subject to too much interference. However, the earliest organisms on the earth that used light energy were actually purple in color.

This is also a relatively normal phenomenon. Because in the spectrum of natural light, blue and purple actually contain the least energy, so purple creatures only reflect purple light and convert all other colors of light into energy.

In contrast, plants are green, which is actually quite unreasonable. Because green contains a lot of energy in natural light, plants reflect all green light, and their efficiency in using light is actually not high. In fact,

, even now, some businesses use purple pigments to harness light energy. But they are already quite rare, so most people think that plants are green.

In fact, today's plants were originally just poor creatures covered by purple microorganisms. The organisms in the upper layers filtered the sunlight, leaving only purple light. These poor creatures who were covered below and couldn't get the sunlight had no choice but to evolve.

There are pigments that absorb purple light energy, and it is precisely because of this that the color of plants is greenish.

It was this pigment that allowed the ancestors of these plants to start photosynthesis, so they created a substance that was more terrifying than the plague at that time, which is now oxygen!

As one of the most common oxidants, oxygen was highly toxic in that era. It even almost wiped out the ancestors of plants. But it was oxygen that destroyed the creatures covering their heads in waves, sending away the first wave.

Those organisms that used purple pigments, and the ancestors of plants relied on their own resistance to oxygen to survive tenaciously, gradually making plants the color we see now.

As for why the plants on Douluo Continent are also green? This is a complex topic that even tulips have not yet understood. After all, it is an accidental plot that a wave of oxygen annihilates them. It does not necessarily mean that purple pigments cannot carry out photosynthesis.

It produces oxygen. So many plants on the planet are green. It is really difficult to explain it by natural selection.

But people who understand this theory should at least know that through genetic modification technology, it is possible to change the pigments used to synthesize organic matter in plants. Green is obviously not the most efficient color. Originally, the infected people wanted to use black directly, but it was a pity that pure black was used.

The plants were often sunk to death for no apparent reason, and the yield was much lower than the current purple variety. Therefore, it was not put into production until the variety improvement was completed.

Due to various factors, the soldiers and assistants of the empire could only watch the infected people on the city wall every day like ants, driving a strange creature with a carapace to harvest quickly in the waves of purple grass.

Experts from the empire analyzed that this is the infected people storing food. They should ferment the grass and then use it to grow mushrooms. This idea was proposed by the domestic doomsday disease forum. These people think about the end of the world all day long.

What to do next, the guy once thought about growing grass on the ground and then growing mushrooms underground, a weird way of survival.

After conducting a feasibility analysis on this, experts believe that this is indeed reliable. Although planting grass may also be used to raise livestock, it is well known that the energy utilization efficiency in nature is actually very low. Each layer of energy

10% is already burning high incense. If you plant grass to raise cattle, it may be difficult to feed so many people underground. What's more, cattle also need time to reproduce. If the livestock are really allowed to grow and develop normally, then the gang underground

The infected would have long since starved to death.

On the other hand, mushrooms may only need a rain to grow. They grow quickly and can effectively convert the protein in plant fibers that humans cannot absorb into absorbable proteins.

In fact, this was also one of the important food sources for infected people in the early days. So much so that many infected people now feel like vomiting when they see mushrooms. It was really the difficult period back then when they ate too much and smelled of mushrooms every time.

I started to feel nauseous at the smell of mushrooms, but of course, I feel much better now.

After the Imperial Army developed a relatively stable source of food for the infected, they no longer wanted to besiege them, and for a while they felt war-weary.
