In short, the first batch of autistic patients who studied with Lin Zeng have become the seeds of the painters, from low to high, teaching the learning skills and ways of painting to other autistic patients.

For Lin Zeng, the number of painters is not too much.

The price at which he buys paper runes has never changed, and even a one-star painter can earn a well-off life by drawing the simplest runes every day.

And that's just how much they earn, not counting the income they earn from teaching other students.

As for two-star painters, their earnings are even higher.

And at present, among the painters, the most capable Madoka, the rune patterns he paints, have always been the best among all the painters at present.

It is also the only one among all the painters who can draw three-star quality runes.

Learning to draw patterns has been a lifesaver for many parents of children with autism.

The paper runes were not only acquired by the Mind Dancer Rehabilitation Center, but after Lin Zeng released a channel in the secret realm that could exchange paper runes for special seeds, other secret realm entrants also bought them from the painters at a high price.

Lin Zeng and Jiang Hua invested part of the funds invested in charity, which was put into support for people with autism. Therefore, the training funds for autistic patients to work as painters come from the arrangement of Lin Zeng's foundation.

The increase in the number of people learning to draw patterns means that there are more and more paper runes in Lin Zeng's hands.

Now, with the one-star and two-star plant refining, Lin Zeng doesn't need to paint the pattern himself. There are enough paper runes to help him refine all kinds of plants.

Promoted to a five-star breeding apprentice, the speed of refining seeds in the refining furnace has been greatly improved, the refining time has been shortened, and the number of refining results has been increased.

A one-star and two-star ordinary seed can be completed in almost fifteen minutes. The refining time of plant seeds above three stars is only half of when Lin Zeng first started.

The number of seeds that can be refined in one furnace of each plant is not the same, and some seeds are extremely small, and each furnace can refine thousands of grains, and the particles are like dust.

There are also some seeds that are larger, ranging from hundreds to thousands of seeds per furnace.

There are also some seeds that are more difficult to refine, and only a few dozen seeds can be harvested at a time. For example, the Ghost Hunt Orchid, each time it is refined, it can only produce about fifty seeds.

A large part of the price of plant seeds in the secret space is also determined by the average number of seeds produced per furnace.

The other part is secretly controlled by Lin Zeng.

The refining furnace of the breeding apprentice could not be refined in batches for a long time in a row, so Lin Zeng had to spend some time every day putting the plant raw materials into the refining furnace and changing the paper patterns of refining at the same time.

He was able to determine that this cumbersome operation would improve after he was promoted to breeder.

In the breeder inheritance of the Xenoworld, there is probably no breeding apprentice who has the resources and conditions to supply such a large customer base.

Only after the promotion of breeders will a large number of exclusive growers be assigned or owned.

In the past two years, Lin Zeng has not continued to increase the number of foundation trees in the secret space. This is also because the number of secret realm entrants today can be said to have reached the limit of what breeding apprentices can supply.

The Phantom Fruit Vine itself is growing.

The number of entrants to the original secret space is increasing. Therefore, it is meaningless to build a new secret space.

Even so, except for some plants that can be refined by themselves, the number of seeds in the secret realm is still not enough to meet half of the needs of today's exchangers.

Anyway, for the entrants of the secret realm, as long as there are enough crystal source bodies that can be exchanged for plant seeds from the secret realm, they can make a move.

At the beginning, because of the invasion of thieves, Lin Zeng added plant locks to all plants in a fit of anger, which really brought benefits to the residents of China.

Because of the restrictions of the plant lock, the entrants of the secret realm can only sell the plants to domestic growers, and even if foreign merchants buy them at a high price, they can only be planted on the land of China.

Otherwise, without the restrictions of the plant lock, it is not known how many of these special seeds will remain in the country under the monetary offensive of some rich capital.

Even with the protection of regional plant locks, foreign capital can still be found by infiltrating China through various ways to conduct research on the cultivation of plants in secret places, or employing Chinese people to grow special plants with high salaries.

Without this layer of protection, like many export commodities, there will be very few people who will be able to enjoy it.

Senhua Forest Farm is a forest plantation farm operated by Huaguo for several generations.

Artificial afforestation, fighting against the desert, storing water and fixing sand, is a jade gem on the Loess Plateau.

Today, not far from this gem, there is a black forest.

This black forest is a treasure in the eyes of the employees of Senhua Forest Farm. They are the gold and silver of this impoverished land. They contain this great wealth.

They are the glazing trees next to the Senhua Forest Farm.

More than 100 acres of varnish trees are planted here, with a total number of tens of thousands.

This is half of the varnish tree plants that the Northern Military Department has exchanged from the secret space in the past two years. The other half is planted in a planting base on another plateau.

The land next to Senhua Forest Farm is too suitable for the growth of varnish trees.

The varnish trees here have extremely high yields of vegetable fuel.

This kind of vegetable fuel has not appeared in the field of people's livelihood for the time being.

The vegetable fuel produced by these two varnishes is directly supplied to the exclusive field of Huaguo.

Refined varnish has a higher combustion energy than flight fuel. In particular, after many tests, the military department gradually replaced the fuel of large combat machines in combat with varnish.

The same amount of varnish can support the use of these machines for a longer period of time.

Moreover, compared to petroleum fuels, varnishes grown in inland areas have a more stable yield.

In the aviation plan, the emergence of varnish and the renewal of fuel have brought new influences to the Huaguo Flying Program and the Space Station Program.

It is not surprising that in the high-end and military sectors, varnish is the first to make an impact.

With the increasing number of varnish trees planted and the increasing reserves of varnish produced, it is an inevitable trend for varnish to move from the field of military aviation to the field of people's livelihood in China.

Eventually, it will replace petroleum resources and make plant-based fuel resources the main source of energy for China.

Of course, this was before other plant energy was not yet widespread.

Xia Baocheng was originally a forest ranger at Senhua Forest Farm, but with the continuous expansion of the varnish forest, he and his colleagues were transferred to the varnish tree plantation by their superiors to be responsible for the daily maintenance of the varnish tree.
