The first fuel grass brick is formulated with green carpet grass leaves, warm blue silver fescue that grows for two months, and low-grade crystalline powder, which can last for three hours.

Warm blue silver fescue is a kind of warm grass plant that Lin Zeng refined when he was not yet a one-star breeding apprentice.

It looks like a fluffy ball of blue fur on the outside, and the leaf color is very beautiful, like a clear blue sky.

Its greatest effect is that it can provide a slightly warmer temperature, especially in the southern winter, and it is very comfortable to put your feet in the warm blue silver fescue.

However, it is not very popular with growers.

There are many inexpensive ways to do this, such as a foot warmer, a hot water bottle and a cotton cover. Therefore, compared with the super sought-after "plant air conditioner" condensed multi-colored ice fairy grass, the market of warm blue silver fescue is really cold.

Back then, when Lin Zeng was the only one refining the seeds, he simply forgot about it and didn't have time to pay attention to it.

However, as this group of learners came out one after another, these low-level botanical forests were screened at the beginning, but they were unexpectedly found that the warm blue silver fescue was very suitable for use as fuel to drive the furnace.

With dried warm blue silver fescue as the main material, mixed with other plant grass leaves, and the indispensable low-grade crystal source powder, it became the fuel used by the first plant refining workers.

The first recipe is mainly suitable for refiners who are at a middle and lower level of learning and can only refine one-star plants.

Its raw materials are all derived from one-star plants, as well as the more popular low-level crystal source body.

The second formula is composed of Peiyuan grass deciduous leaves, flame gate triangular plum fallen flowers, electric lotus seed petals, warm blue silver fescue with a growth period of half a year, and low-grade crystal source powder, which can continue to burn for 12 hours. That is, the burning grass bricks that Lin Zeng gave them in the graduation gift package.

Among them, the flame gate triangular plum and the electric lotus seed petals are two-star plants. To obtain these plant materials, refiners can either grow them themselves or buy them from the market.

The last formula can continue to burn for forty-eight hours without stopping. It increases the amount of low-grade crystal source powder, and at the same time, the main raw material is the leaves and twigs of the lignified Rubus hook, and is also supplemented by the falling flowers of the Flame Gate Triangular Plum.

The botanical sources of these three formulations are not difficult, as long as these novice refiners are willing to buy from the market and find a stable supplier, there will be no shortage of fuel.

Of course, a safer way is to get the seeds of these plants and build your own planting base.

In the short term, it is the unanimous idea of these refiners to use the acquisition model to make fuel grass bricks, and in the long run, to establish their own planting base.

Qi Lin is probably the one who is the most worried about the source of raw materials.

As the largest supply company of secret realm plant seeds at present, it was very easy for him to find these plant raw materials and plant seeds.

Following the operation in the learning space, Qi Lin skillfully drew the smelting pattern on the flame furnace.

On the surface of the flame furnace, the temperature is slightly hot, a few degrees higher than the body temperature, on the contrary, the silver frost furnace is cool to the touch.

The use of the Silver Frost Furnace has a sense of smoothness like a finger, and it is possible to judge the situation in the furnace more accurately.

With the use of a flame furnace, it is difficult to clearly know the smelting of the materials in the furnace, which makes Qi Lin very unaccustomed to using it.

……

While Qi Lin was refining, he was constantly comparing the differences between the two Ding furnaces.

There is a big difference between the two, and the pros and cons are immediate.

About an hour later, the plant seeds in the flame furnace were formed, Qi Lin wiped the hot sweat from his head, extinguished the fuel grass bricks, and lifted the lid above the flame furnace to check the refining situation.

Refining seeds in the inheritance space, each time it is completed, there is a hint to inform the refiner of the results.

And with the Flame Furnace, Qi Lin could only make statistics by himself.

Qi Lin took out all the seeds in the furnace and counted them in detail.

Two hundred and three high-yielding vine watermelon seeds.

Less than half the amount refined in the Silver Frost Furnace.

And it took an extra twenty-three minutes.

Regarding this result, Qi Lin guessed a few points during the refining process.

Compared to the smooth refining feeling in the study space, the use of the flame furnace obviously felt bumpy, as if he had just started studying two years ago.

Qi Lin was not discouraged, he put this batch of seeds in units of 100 seeds, put them in empty packaging bags, and then marked the varieties and dates with labels.

All the plant seeds refined by Qi Lin were supplied to Xeno-Tim.

Although the efficiency of the Flame Furnace is not comparable to that of the Silver Frost Furnace in the learning space, it has an important advantage.

It has no usage limits.

In the past, if Qi Lin wanted to refine seeds, he could only do so in the learning space.

For two hours a day, you have to learn new rune patterns, refine seeds, and exchange materials, and often you can refine two furnaces of plant seeds at a time, which is already very good.

And now, according to his weekday schedule, an average of more than five furnaces of seeds per day is more than enough.

And that's on the premise that he allocates a lot of time to the research that has just been obtained.

Qi Lin is determined.

Although he did not pass the assessment, he had a black stone pattern in his hand and was able to re-enter the learning space for five days within a year.

What he has to do now is to work hard to refine the seeds and save money to continue to exchange for more study materials.

This group of plant seed refiners left the inheritance space and entered the source of seed supply, marking the beginning of the real development of the plant civilization in the alien world in the earth world.

It is difficult to support a single tree, it is difficult to travel alone, and the seeds of the secret realm are very famous, but the supply is too small.

Qinghe City is slightly more popular, but looking at the whole of China, it can only be said that tens of millions of people are looking forward to it, and the number is not enough to stuff their teeth.

Long Hongwei, a lazy ghost, originally wanted to live a lifetime by refining condensing multicolored ice fairy grass, but it was really not nonsense.

Every learner who walks out of the inheritance space is filling a huge demand void.

It may not be obvious at first, but as their number increases and the refining time accumulates, these plants born from the Ding Furnace have real influence.

The emergence of the seed refiner has made a great change in the research direction of scientific research institutions that are trying their best to conquer the plants of the secret realm.

Originally, the appearance of the secret realm entrant misled the research direction, if the seed refiner did not appear, the direction of their exploration, towards the mysterious space, the multi-dimensional world, all the way to the ground, there is a reason.

The secret realm is a mysterious space that suddenly appeared in Huaguo due to some unknown factor.

And when the refiners and the runes they learned appeared in the research topic, all of them came out of the dead end of their original ideas.
