Just collecting the high-quality primary crystal source body used for promotion took Lin Zeng two full years.

Plants that have been refined by breeders are able to absorb substances from other dimensions, so many plants can still thrive even if they do not have abundant water, fertilizer and sunlight.

Plants with large mutations can absorb some special energy from different spaces.

In the process of absorbing the energy of the other space, the roots of special plants will condense crystal source bodies, which are the hard currency of breeders.

Because it is a consumable, the crystal source has a higher value than the earth's gold and silver.

The quality of the crystalline body produced by different plants is different.

As a breeding apprentice, Lin Zeng refined most of the plants that could only produce primary crystal source bodies. Of course, it is not excluded that there are very few plant varieties that can obtain intermediate crystal source bodies through special methods.

Lin Zeng has been refining plants for many years, and the only plant that can really produce an intermediate crystal source body is the Ghost Hunt Orchid.

The same is to produce primary crystal source bodies, and the quality of primary crystal source bodies of different plants is not the same.

The vine red jade tomato, a fast-growing plant such as a one-season tomato, produces the worst quality of crystal source bodies.

Almost every crystallized crystal source contains less than 1.5 units of energy.

In fact, the only way to grow one-star tomatoes and red jade tomatoes is to obtain more crystalline units by increasing the planting area.

Plants with a long growth life usually obtain better crystal source quality.

Indoor vine vegetables with a growth period of about a year usually contain 3-5 units of energy in the crystalline source body when the soil is turned over at the end.

In the case of a longer-lived crystal, after the end of the twenty-year growth period, its root system can often harvest a primary high-grade crystal source body containing 30-50 units of energy per grain.

Fortunately, Lin Zeng was promoted to breeder, and he did not need such a high-quality crystal source.

He only needs more than ten units of energy in each crystal source body, which can meet the needs of the promotion.

This quality of the crystal source body is quite easy to find in the alien world. The cultivation history of the Xenoworld is very long, and such a crystal source body is completely the quality used by ordinary apprentices, and it is not rare.

On the contrary, the crystal source body with the largest number of crystals in China today only contains one or two units of energy, which is very rare in the Xenodimensional world.

The grade of this plant is too low, the taste of the product is average, and the quality of the condensed crystal source body is extremely poor.

There will be no growers who will waste land with such failing seeds.

Unfortunately, in the time and space of the earth, there is only one breeder like Lin Zeng, so the plants that Lin Zeng refined when he was not yet beginner are also promoted and planted to a high degree.

In particular, those who have just obtained the qualification of a secret realm entrant can achieve the purpose of accumulating the wealth of the crystal source body by planting this fast-growing plant.

In the field of currency, this quality crystal source body is like a dime for a dime, and most of the customers trade with Lin Zeng through this kind of scattered coins.

When Lin Zeng was promoted to breeder, he only needed a one-yuan banknote.

For Lin Zeng, the hardest thing is time.

Some plants that are easy to condense high-quality crystals have not yet reached the growth limit, and the root crystals have not yet developed to the standards they need.

Only by being patient can you get it

At present, the crystal source body containing more than ten units of energy per grain can be harvested, although there are some, but it cannot meet the amount that Lin Zeng needs.

All Lin Zeng could do was wait.

Therefore, in the past two years, the secret realm entrants of the major secret realms have found many special and high-value plants, products, and materials, which can only be exchanged for high-quality crystal source bodies.

Life Extension Fruit: The exchange requirement is that each grain contains ten units of energy source body, and the exchange quantity: 800 unit crystal source body.

Shujing Lotus: Each grain needs to contain 10 units of energy source body, and the exchange quantity: 400 units of crystal source body.

Microspace Strawberry Farm Ring: Each grain needs to contain ten units of energy source body, and the exchange quantity: 600 units of crystal source body.

……

With the revision of the exchange requirements for plants in the secret realm, various organizations and individuals who exchange plant seeds from the secret realm no longer blindly expand the number of tomato fields, and only exchange them for ordinary plants by planting one-star tomatoes to maintain the base number of crystal source bodies.

At the same time, the planting area of other plants that can produce high-quality crystal source bodies will be increased.

Anyone who sees the attributes of the longevity fruit and the lifespan it can increase will feel hot in his heart, and he can't wait to exchange three longevity fruits at once to increase the lifespan of his friends and relatives.

Eight hundred units of crystal source bodies are very easy to put together, and basically any secret realm entrant who has undergone a year of development has this family background. But with the previous restrictions, there are not many people who can have this accumulation.

The requirement of the crystal source body is only a necessary condition for the promotion of breeders, but it is not the only condition.

In the past two years, the musculoskeletal of Lin Zeng's body, through the refining of the essence of the leyline fruit, has been slowly improving, but it has not reached the limit of the body.

He is still in the stage of a five-star breeding apprentice, accumulating the power to break this class.

His body was improving, and his brain was not stagnant.

Unlike promotion during an apprenticeship, promotion to breeder has strict restrictions on how much you can learn about the inheritance.

A hard condition for the promotion of breeders is that Lin Zeng's chosen breeder branch must have two specializations that reach the excellent level of apprenticeship and the other specialization that reaches the good level of apprenticeship.

Lin Zeng chose three breeder branches during his breeding apprenticeship.

Urban breeders, marine breeders, and giant breeders.

In other words, Lin Zeng must master all the knowledge systems under this classification.

From runic patterns, to refining techniques, from basic theory to practical application.

This condition requires a lot of time and a frightening number of crystal source bodies. Because if he doesn't have money, he can't afford to buy study materials.

Therefore, in the past two years, when many secret realm entrants had developed rapidly, Lin Zeng had become even poorer.

Except for the ten units of one crystal source body that were stored, the other crystal source bodies were almost exchanged for Lin Zeng's use.

The process of continuous enrichment of learning is not only about memorizing and inheriting materials.

In the breeder system, the knowledge learned must eventually return to the event.

The cultivated seeds, the value of the plants they represent, are the real achievements of a good breeder.

In this process, Lin Zeng studied and studied, and then applied refining, and the plant varieties in his seed world also increased day by day.

Due to the constraints of the conditions, Lin Zeng focused on the research of urban breeders and giant breeders, while the research time on marine breeders was slightly reduced.
