In the past, Chang Le rarely used low-grade spirit stones to practice, because low-grade spirit stones are not more cost-effective than using elixirs to practice.

But the medium-grade spirit stone is different. The spiritual energy of heaven and earth in the medium-grade spirit stone is several times that of the low-grade spirit stone, and it is very rich. If you practice with medium-grade spirit stones, the cultivation effect will definitely be twice the result with half the effort!

After estimating, there are about 500 medium-grade spirit stones inside. The medium-grade spirit stones are converted into low-grade spirit stones, which is a ratio of one to one hundred, with a total of 50,000 low-grade spirit stones.

Fifty thousand low-grade spirit stones are enough to maintain the expenses of a small family for more than half a year, and they are definitely a huge fortune!

What's more, medium-grade spirit stones are rarer than low-grade spirit stones. In fact, they are worth 50,000 low-grade spirit stones, and 70,000 to 80,000 low-grade spirit stones are extremely likely. Even 100,000 low-grade spirit stones, there is no wonder.

Chang Le knows the truth that wealth is not exposed, and cannot be exposed until he has enough strength. Therefore, Chang Le secretly warns himself to put the spirit stone in his hand back into the storage ring.

Afterwards, his eyes fell on the two secret books in the center of the space. With a thought, these two secret books appeared in his hand. When he opened it, he found that it was a body refining technique.

"The bronze body refining technique belongs to the low-level spiritual level exercises, and is divided into five levels. The first level is the copper body quenching; the second level is the bronze body protection; the third level is the broken copper rebirth; the fourth level is the bronze gold body; the fifth level is the blue and white body." Chang Le's face turned ecstatic and murmured to himself.

If the secrets of low-level spiritual level are placed in the sect library, the outer disciples are not qualified to read and practice. Even in the inner disciples, there are very few disciples who can learn low-level spiritual level skills.

Because it takes a considerable contribution point to exchange for a low-level spiritual body refining technique, ordinary disciples have no way to make enough money, so they can only sigh.

At this moment, what was placed in front of Chang Le was a low-level body refining technique. You could read and practice without contributing points. How could he not be ecstatic?

After suppressing the excitement in his heart, Lin Chen pondered and said, "The bronze body refining technique combined with the bronze essence cultivation can achieve twice the result with half the effort. However, this bronze essence is extremely rare, and the price is not a small amount. I have to plan it carefully."

If this secret book hadn't introduced the bronze essence in detail, I'm afraid Chang Le had never heard of this thing. However, it would be good to have bronze essence, but it would be fine if it didn't.
