Guiyuan Survival

Chapter 218 Teacher Lan's efforts at the beginning were really "painful"
Teacher Lan grinned at everyone in a wicked way, and made a fake gesture of opening the gift box in his hands. After firmly seizing the students' attention, he quickly put away the gift box and put it in the storage utensil inside.

Immediately, all the students complained, and they cursed a few words in their hearts in disappointment, they are really too stingy!
Teacher Lan didn't care how strong their disappointment was, he just lay down on the desk, chose a comfortable position, and went to wander in the world of "Miracle".

Today, the grades of energy minerals that have been discovered in Zihan World vary, and the cultivation world divides them into seven grades according to the energy content of the raw ore.

Referring to the cultivation level of Yuan Wushi in the early stage, the order from low to high is red, orange, yellow, green, blue, blue, purple, and 100 is used as the conversion unit between adjacent grades.

In the same way, after special treatment, the primordial energy stone is also judged to be of different grades according to the grade of the raw energy stone before processing.

In short, it is what grade the raw energy stone is, and what grade the processed primordial energy stone is, regardless of the energy utilization rate.

It would be too troublesome to subdivide the energy utilization rate.

Therefore, under the same rank, Yuan Energy Stone can be roughly divided into three ranges according to the energy utilization rate.

The energy utilization rate is lower than 50%, excluding 50% is low.

The energy utilization rate is between 50% and 70%, including 50%, and excluding 70% is intermediate.

The remaining energy utilization rate is above 70%, including 70%, which is advanced.

Under normal circumstances, a piece of red-grade low-grade energy stone can provide an ordinary family with a month's energy consumption, including cooking, housework, lighting and so on.

From this, it can be imagined that the raw energy stones consumed by Yuan Duoduo's epiphany at that time caused Teacher Lan's heartache so much that it directly broke his usual gentle and indifferent expression, which is completely understandable.

After all, in the world of Zihan, energy stones and raw energy stones are generally sold as commodities, rather than directly as currency.

As for the common currency of Zihan World, it is the Rainbow Star Coin that the Fifth Sister Yu Longxuan, who had helped Yuan Duoduo in Huanyue World, once gave out.

For the convenience of use, the Rainbow Star Coin still uses the division of Yuan Wushi's level. There are seven denominations, purple is the most, and 10000 is used as the conversion unit between two adjacent denominations.

On the front of the physical Rainbow Star Coin, there is a relief of Eternal Xishen printed on it, and on the back is a lotus flower of twelve colors and twelve petals representing twelve elements, one petal of one color.

The utensils for making these physical rainbow star coins come from the improved version of the star coin making machine of the energy converter in the original fantasy world.

The raw material is mainly the residue of the original energy stone for making the energy stone, of course, all other things that contain energy can also be used.

These raw materials are filled into the star coin making machine, and a small amount of harmless dye is added. The final product is a circular coin with a diameter of 1.5 cm and a thickness of 0.2 cm, with rainbow colors.

Each rainbow star coin produced in this way naturally contains pure energy, or processed non-attribute energy, which can be directly absorbed, or put into various energy devices to replace energy stones.

As for the star coin circulating on the star network, it is just a virtual form of the rainbow star coin.

Yuan Duoduo didn't know about the "eyebrow lawsuit" in the classroom after he practiced.

When a class was over, Yuan Duoduo also ended his practice as the bell rang.

Still the same as usual, Yuan Duoduo "routinely" started to sort out the inherited knowledge he had received after everyone finished his meal.

Through those inherited knowledge, Yuan Duoduo had a deeper understanding of Wanxiang Sect.

What surprised Yuan Duoduo was that the tenet of Wanxiang Sect was very similar to the current Zihan World's attitude towards the utilization and protection of energy.
