Wizard: I brought the wrong system.

Chapter 546 Eight Extremes - Devouring

Vitality itself has the function of nourishing the body, but passive nourishment is definitely not enough, and the coverage of the eight systems is too broad, so it is impossible to cover them all at once.

Therefore, it's best to prioritize them and then reinforce them purposefully according to your own needs.

Of the eight bodily systems, which one should be strengthened first?

I personally think it should be 'digestive system'.

Because the 'digestive system' is related to nutrient intake and is the cornerstone of all bodily systems.

Just like a car's fuel tank, only with sufficient nutrition can a strong body be supported.

Moreover, with a stronger digestive system, it can better extract nutrients from food, reducing the need for food, lowering the barrier to entry, reaching a wider audience, and enabling better dissemination.

So, what are the directions for strengthening the digestive system?
Yaro thought that the vulture could be used as a reference.

They can eat rotten flesh every day without any problems, eat bones as snacks, and even digest metals.

If someone had such an iron stomach, then any disease that comes from the mouth would be a joke!
How do vultures manage to do that?
Previous studies have shown that vultures have a very low stomach acid pH value. The normal human pH value is between 1.5 and 3.5, while the vulture's stomach acid pH value is between 0 and 1!

It's important to know that pH changes are calculated in powers of 10; for every degree the pH decreases, the acidity increases tenfold!
Therefore, the stomach acid of vultures is actually tens to thousands of times stronger than that of normal people!
Raising stomach acid pH is simple; it can be done in a way that's like a "life-threatening situation," using a three-pronged approach to stimulate the stomach wall cells to secrete more hydrogen chloride, thus increasing acidity.

The problem is that the human body cannot tolerate such a high concentration of strong acid.

Raising the stomach pH level abruptly is no less effective than drinking sulfuric acid directly.

Moreover, the digestive bacteria in human gastric juice, as well as the enzymes that promote nutrient absorption, cannot remain active at such a low pH, and may even be directly decomposed by strong acids.

Yaro quickly came up with a solution to the problem of bacterial colonies.

“A stomach acid pH of 1.5 is within the human body’s tolerance, but a normal person will not always maintain such an extreme pH. So you can gradually raise the stomach acid to this level, and with the nourishment of life force, maintain it for a period of time. Those colonies that cannot tolerate it will naturally be eliminated, and the rest can continue to be cultured.”

The colonies reproduce very quickly, potentially doubling every 20 minutes under ideal conditions.

Moreover, bacteria are very small. A colony the size of a fingertip can contain thousands to millions of bacterial cells. If just one of these millions of bacteria can withstand higher stomach acid, it can return to its original level within 4 to 6 hours.

"Just like how children in the previous life supplemented their diet with probiotics, we can also actively seek out symbiotic colonies that can survive in this level of strong acidity."

For example—actively ingesting 'Swallowing Heaven Sand'?
Um, this is a new "medicinal herb" named by Yaluo, referencing names such as "silkworm excrement", "night-shining sand", and "moon-gazing sand".

A name should naturally be imposing, otherwise how can it fool people?

But in reality, it belongs to vultures...

"It's disgusting to even think about. I might as well consider eating bird stomachs raw. Although it's still a bit... it's better than 'Swallowing Heaven Sand'. Ordinary people might consider 'Swallowing Heaven Sand' since it's easy to obtain."

Because fungi reproduce very quickly, you don't need to eat a lot; just a little bit is enough to act as a 'guide drug'.

Besides the acid problem, the second problem is the enzyme.

For example, pepsin, which helps digest the protein components in food in the stomach, exists because of human needs. Therefore, it can only exert its best effect in a pH range of 1.5-3.5. Higher or lower pH ranges will affect its normal effect.

This information is etched into the human genome and is very difficult to modify. Therefore, there is only one way: to add vitality and use this extraordinary power of 'vitality' to support its activity.

Besides symbiotic bacteria and digestive enzymes, an even bigger problem with overly acidic gastric juice is that the stomach wall cannot contain it.

Yaro would naturally not choose to have a vulture's stomach transplanted.

The human body is an invincible path, why would it need to borrow the stomach of a vulture!

Uh… Yaro patted his head.

It's a channel mismatch!
Back to topic.

Human stomach acid is acidic, just not to the extreme degree of vultures.

So how does an average person's stomach overcome acidic gastric juices?
In normal individuals, the stomach wall secretes a viscous fluid called mucus, which is mainly composed of mucin and carbohydrates. This mucus has a buffering effect and can protect the mucous membrane from erosion by stomach acid.

In addition, the stomach wall will continuously repair and regenerate, using continuous recovery to counteract continuous erosion.

Simply put, the key lies in the stomach wall.

The way to break through the limits is the same: nourish the entire stomach wall with vitality—which requires a high level of 'vitality'.

Then, behind the stomach is the small intestine, which mainly absorbs nutrients. Between the stomach and the small intestine is the pylorus, a muscular flap. If stomach acid is increased, this pylorus also needs 'vitality' to support it.

There are also the small intestine walls, bile salts that neutralize stomach acid and digest fats, and pancreatic juice secreted by the pancreas to neutralize the acidity of gastric juices... a whole series of processes need to be strengthened!
"This is too troublesome! And too difficult!"

Therefore, achieving all of the above abilities is only a state of perfection; the entry requirements should not be so high.

So how do you define "beginner"?
After a moment's thought, Yaro decided to further subdivide the levels.

"At the beginning, you can actively send information to the brain, which will make the food you eat more digested."

This is the same as the previous "Death by the Gates" Plan 3 operation mode, which amplifies the information transmitted to the brain and causes the body to actively secrete various hormones related to digestion.

They look no different from ordinary people, but in reality, they are quite different.

For an ordinary person to achieve this, they would need to have very regular eating habits and always be able to eat foods that best suit their taste at the time, thereby maximizing the efficiency of their digestive function... which is naturally unrealistic.

"Proficiency in using weak stimuli to target key parts of the digestive system, and the ability to activate them only for short periods of time, thereby gaining the capacity for rapid digestion."

Although the pH value of human stomach acid is 1.5-3.5, it can reach as low as 1.2 under special circumstances. Don't underestimate this small difference of 0.3, as it is three times the extreme value.

This is still the normal situation for ordinary people.

In special circumstances, the pH value can even be lower, but this can harm the stomach.

If the time it's open is short, the impact won't be too serious... It might get damaged, but it can still repair itself.

It can be used in emergency situations.

For example, brief breaks during prolonged battles.

Or, in special circumstances where food is scarce and every drop of nutrition in the food must be absorbed.

"Perfection means that vitality can cover every detail of the digestive system. This step requires the key ingredient—Tuntiansha."

As for the name, Yaro is tentatively named 'Baji-Tun'.

Eight, the eight systems of the human body.

Extreme, to the extreme.

To swallow, to eat.
