In fact, there are many types of power food in the main world, but basically all of them are innate, such as some plants, farming, and fruits that contain huge vitality in themselves.

For example, fierce beasts, sea beasts, flesh and blood, etc., which have a huge vitality and reach a certain quality, can be regarded as natural power food by the aborigines of the main world.

Therefore, the power grain, in fact, is a broad general term, in fact, all substances that contain huge vitality can be regarded as force food.

Because it itself contains rich and high concentration of nutrients and energy, but all of the above are actually natural power foods.

And the power grain that has been refined in large quantities the day after tomorrow, there are only a few kinds of power grains in the main world.

Croton is a kind of acquired power food refined by the aboriginal humans of the main world after countless years, and it is one of the few power foods that is the most popular and cost-effective.

According to Li Yunmu's understanding in Cangyue Island in the past few days, 90% of the world's martial artists, croton is their indispensable food.

A martial artist with the strength of less than 50 oxen must eat at least five to ten crotons every day for the most basic needs of the body, in order to barely maintain the needs of the body's functions without causing weakness.

If you want to be stronger and more progressive, then you need to eat more crotons every day.

A string warrior class, if you want to ** the maximum maximum enhancement per day, you probably need to eat extra food every day, thirty to one hundred crotons, to reach the limit.

In other words, if you want to practice faster and improve your physical strength, then the number of crotons that a martial artist needs to consume every day is far more than five or ten.

Rather, it is the lowest standard, which will reach thirty to one hundred, depending on the degree of absorption of the power grain by each martial artist.

If the absorption potential is small, 30 pills per day is enough, and if the absorption potential is large, more than 100 pills are needed every day.

If an individual has practiced an extremely high and supreme body quenching technique, then a hundred pills are far from enough, and more is needed, so it is no exaggeration to say that the Croton power grain in this world is actually a necessary food resource for cultivating the physical body.

In the mouths of the commoners of the main world, there used to be a crroton for a ton of rice, which means that the price of a croton is enough for them to buy a ton of rice.

Before the Dark Age of the Earth, it was said that the poor were rich and martial.

It can be seen that this sentence, even if it is placed in the Overworld, is also appropriate.

The Overworld is so vast that almost no one can measure its end, and the life it has is naturally endless.

It is said that the human race alone has a population of more than 3 trillion people according to the one-sided statistics known in the Overworld.

This is still the population of some cities and towns that are known to be surveyable, and as for the wilderness, God knows how many still exist, and it is impossible to find out how many are certified.

But even then, more than three trillion people are known.

It was enough to shock Li Yunmu, but only now did he understand a little, why are the aborigines of the main world inherently strong, and in such a large base of population, the number of martial artists is so small?

It's not that the natives of this world don't have the qualifications and talents to cultivate martial arts, but that they are too poor, and most of them can't keep up with the supplementary consumption of power food.

Similarly, Li Yunmu also woke up to the fact that when he was on the earth plane, he obviously practiced the supreme body quenching technique of the Great Sun Overlord Body Duel, and also cultivated the Dragon Demon Bone Refining Duel.

A **, both inside and out, but in the end, the power he can explode can barely reach the strength of more than a dozen cows?

It turns out that the rules of heaven and earth seem to have silently imposed a shackle on all human lives in the world.

That is, when the strength of human physical fitness breaks through the power of fifteen oxen, then there is no corresponding food supply to increase energy, and it will reach the limit.

This is the fundamental reason why Li Yunmu only has the power of eighteen oxen until now.

Obviously, the power of the three bulls that surpassed it was all unintentionally increased by him when he came to the main world and fed on the meat of fierce beasts every day.

Therefore, if you can toss how to refine croton, this has become a major matter of Li Yunmu's short-term goal, it is said that the refining method of croton, this kind of power grain, is mainly in the hands of an ancient clan that has been bred for tens of thousands of years.

Li Yunmu would naturally not be stupid enough to go against such a terrifying ancient power clan in the main world, but if he could use the system's huge actuarial power to assist, plus the True Refining Tower that had flickered from the hands of Chaotian Sect.

Perhaps, he can really imitate a kind of power grain similar to Croton, and he doesn't need to promote this power grain to make a lot of money.

He only needs to control the scope within all the affiliated islands of Cangyue Island, then it is enough to take this opportunity and earn enough wealth.

This wealth was enough for him to purchase various secret methods, as well as a string acupuncture point that should be missing.

That's right, this is the way Li Yunmu wants to go, as for tossing the top ten stone house masters, and receiving those ten contribution points every day? This is really nonsense.

God knows how long it will take to accumulate enough contribution points for what he needs to buy.

After receiving the relevant refining materials about croton delivered by the system, Li Yunmu studied it carefully, and his brows were sometimes tight, sometimes relaxed.

The fierce beast essence blood with a certain vitality strength quality, this main material, he already has.

The large number of sea beasts that the ten shadows killed every day was enough to use the Refining Tower to refine them into a large amount of essence blood, which was why Li Yunmu had the confidence to fight the imitation Croton.

Not because of anything, just because he happened to have a Supreme Sacred Weapon related to refining.

The Refining Tower, which flickered from Chaotian Sect, had a total of nine floors.

The first layer is refining essence, the second layer is refining qi, the third layer is refining gods, and as for the sixth layer after the third layer, because Li Yunmu's strength is not enough, he simply does not have the strength to step on the fourth layer.

However, even so, the first three floors of this Refining Tower were worthy of the prestige of the Supreme Sacred Weapon, and it was worthy of its status, which was even higher than the Void Wheel.

In the Tower of Glory, Xianzu left a total of three Supreme Holy Weapons, the Wheel of Void, on the twenty-fifth floor.

The Well of the Moon, placed on the fiftieth floor.

The Refining Tower, placed on the seventieth floor, is regarded as the supreme of the supreme holy artifact, and now, this supreme treasure has finally embodied its due value.

The raw materials that are in the greatest demand, a large amount of fierce beast flesh and blood have been solved, so in fact, what Li Yunmu needs to face next is this kind of mild concoction liquid with unknown medicinal properties that has been systematically analyzed.

Li Yunmu could be sure that the secret technique of croton's refining was largely in this mild blending liquid.

"System, can you accurately analyze what kind of liquid it is, or what can be used to replace this blended fluid?"
