With the double return gift from Yan Hua, country M soon became lively.

Yan Hua stayed peacefully in the air base for three months.

These three months are enough for the air base to recuperate and recover.

Not only to recover his vitality, but with the good things that Yan Hua had looted before, the air base was in full swing, developing batches of new medicines, new weapons, as well as new food crops, and food substitute preparations-primary nutrient solution.

In fact, the nutrient solution has been used in hospitals for postoperative clinical practice before the end of the world.

Generally, just after surgery, the patient is in the stage of fasting and water fasting before exhausting.

Some people pass gas very quickly and may be able to eat some liquid food on the same day, but patients who have undergone major surgery or have a weak constitution may not pass gas for three to five days.

If you can't replenish water for such a long time, normal people can't support it, let alone a patient who has just undergone surgery and is weak?

Before the nutrient solution was developed, patients were supported by saline and glucose.

But it is difficult to heal the wound and recover quickly.

In the fast-paced life of today, no one can afford to spend a year and a half to recuperate.

This is where the nutrient solution comes in.

Generally, minor surgeries use a yellow transparent water-like nutrient solution, which is enough for the patient's daily nutrition to be about 3500ml.

For patients who undergo major surgery or are too weak, they use a milky nutrient solution, which is a concentrated 3500ml of nutrients except for 50% glucose.

Such a large amount is still a traditional intravenous injection, and it takes at least ten hours to inject a drip to supplement a nutrient solution.

At that time, it was a feat and a self-breakthrough in the medical world.

Because of the birth of the nutrient solution, the speed of healing of the incision and internal wound after surgery has increased exponentially, and the speed of recovery has also accelerated.

It used to take half a month to remove the stitches, and it has become a thing of the past to go back to recuperate for three months to half a year.

Hospitals have finally kept up with the fast pace of society and have greatly reduced the time for removing stitches.

One week after the operation, the stitches can be removed and returned home for recuperation.

In addition, the amount of nutrient solution used after surgery directly affects the speed of subsequent recovery.

But this thing, in the last days when it can be fatal anytime and anywhere, has become a chicken rib.

No one has the time to wait for ten hours.

No one has the leisure time to spend that long "eating".

The pace of the last days is faster than that of the peaceful and prosperous times.

Especially for the new supernatural beings who have appeared after the end of the world, the 3500ml bag of nutrient solution is not enough for them at all.

To supply their bodies with the nutrients they need, they need at least five to ten 3,500ml bags of milk-like nutrient solution.

Such a huge amount of time, Yong for a long time, has long been unsuitable for use in this chaotic era.

However, it is difficult to re-concentrate the past nutrient solution to make a new nutrient solution.

Because that's the ratio that is best for the body to absorb.

If you continue to concentrate, it is difficult for the human body to absorb quickly, which will cause a huge burden to the human body, and even damage, which is the most difficult difficulty to break through.

The formula of the nutrient solution reagent given by Yan Hua made the eyes of the scientific researchers shine.

And in the process of in-depth understanding and development, it suddenly became clear.

The formula of this nutrient solution truly concentrates the nutrients needed by the human body and extracts the essence.

Because several of these important substances can protect the gastrointestinal, liver, and kidney blood vessels, and at the same time, they can promote their rapid decomposition in the stomach and intestines.

A large amount of nutrients are stored in the blood and muscles, like a granary, and then gradually absorbed by the body.

This process of absorption varies from person to person.

The average person can last seven to ten days, always feel full, and will not be hungry.

The Adept can use his own hedron to absorb these nutrients, which will be consumed faster.

Generally, low-level abilities can last for three to five days of satiety.

The number of abilities above level 5 is gradually decreasing.

A Level 9 Ability may only be able to sustain a full meal.

Yan Hua is an outlier, and he needs to drink about three to five bottles at a time.

That's right, it's a bottle, not the kind of test-tube cocktail she owns.

A bottle of this primary nutrient solution is about 300ml, and the taste is indescribable, and it is absolutely not related to the taste.

Even if the researchers adjusted the taste as much as possible, the final product was similar to drinking saccharin glue with bitter gourd and garlic.

emmmm, the taste is so hard to describe.

Even though the taste of this thing is so weird, after it was successfully developed, it was still sought after by the supernatural and coaxed for a while.

The nutrient solution can not only fill the stomach, but also quickly restore the energy consumed by the abilities, and can also promote the rapid healing of wounds.

Such a life-saving artifact, even if it tastes a little worse, using it as a life-saving medicine can make countless supernatural people ignore its taste.

The new weapons are all supplied to the military, and no news has been leaked.

Many of the auxiliary potions are open to the Abilities.

But it's not so easy to get, you don't have enough contributions to the air base, you don't have a certain number of tasks, and the difficulty of the mission is not enough, so you can't get those precious potions.

......

The air base is thriving, and the more it goes, the better.

Country M, on the other hand, is living in dire straits, with heavy casualties.

Top zombies gathered, a large number of marine creatures landed, and the Tianyan system was also paralyzed for some reason.

In such a situation, country M relied on alien technology to forcibly fight for two months, and finally collapsed and began to flee in all directions.

There were constant disputes between those in power, and opinions could not be unified, which led to the dispersion of the last power of country M.

A part of the "Chongwai" rulers, with their armed forces, followed the remnants of the aliens and fled by land from ELS to the direction of Huaguo.

The destination pointed directly to the air base where Yan Hua was located.

Although this part of the armed forces is still strong, how Yan Hua captured their same troops, the top brass all knows it.

So this time they fled to Huaguo, and their goal was not to occupy a random piece of territory, but to come to ask for help.

Of course, on the surface, it is under the lofty guise of cooperating with China, sharing resources, co-existing, and defending against foreign enemies.

By the time country M used alien technology to quickly escape to China, ignoring the large and small bases all the way, went straight to the air base, and came to the foot of the magnificent floating island in the air, it was already a month later.

Today's air bases are no longer what they used to be.

The area with the most severe paralysis of the Heavenly Eye is here.

Therefore, the change of the air base, the impression of the top management of country M, is still stuck in the impression of nearly a year ago.

Looking at the increasingly solid air fortress, all the people who fled here in country M were in a very complicated mood.

The shock and yearning are indescribable, and facing such a magnificent and miraculous Dream Sky Island makes them feel so small.

Just when everyone in country M couldn't come back to their senses, a loud shout exploded in their ears.

"Who?"
