Chapter 4494 (1/2)

At the top of the Dan furnace, there are 36 transparent beads, which are colorless and transparent under normal circumstances. Once the alchemy starts, a bead will light up when the temperature in the furnace rises to a certain height. The higher the temperature in the furnace, the more beads will light up!

This is equivalent to having a thermometer with only 36 scales in the Dan furnace.

Although there are only 36 scales, it is basically enough for most alchemists!

Because... In the process of lighting a bead from the beginning to the extreme, and then lighting the next bead, you can also divide it into 10% to 10% by the brightness of the bead. If it is subdivided in this way, the ”thermometer” on the Dan furnace has 360 scales, which is quite fine.

Of course, it is quite difficult to distinguish whether a bead is 30% bright or 40% bright. This still requires some experience.

If the subtle temperature is not clearly identified, it may not lead to the failure of alchemy, but... Most of the refined pills will not be of high quality!

Lu Shan had no experience before, and naturally he could not accurately distinguish what a bead looked like when it was almost bright.

Therefore... He didn't rush to put in the medicine, but when the fifth bead on the Dan stove lit up, he began to carefully adjust the temperature of the Dan stove.

He repeatedly let the fifth bead light up and slowly heat up until it reaches the extreme, and even when the sixth bead began to shine slightly, he began to reduce the temperature of the flame and make the fifth bead dim slowly again!

After doing this repeatedly for six times, he could finally accurately judge the brightness difference of a bead, and then steadily fix the temperature of the Dan furnace at the level of four beads and seven.

The so-called four beads and seven, that is, the first four beads should be lit up, while the fifth bead can only be lit up to 70%!

For the new alchemist... Controlling the temperature is the most difficult. Even if you can find the temperature right at the beginning, it is not so easy to control the ground fire to stabilize at the same temperature without changing the temperature of the Dan furnace!

After all... When the temperature of the Dan furnace reaches a certain level, it doesn't mean that you can keep the flame at this level... If you continue to maintain the existing flame temperature, it will only make the temperature in the Dan furnace continue to rise! Therefore, after the temperature reaches the standard, it is necessary to slowly reduce the temperature of the flame!

However, the temperature of the flame cannot drop too fast. Once the flame temperature drops too fast, the temperature in the Dan furnace may also be reduced too much, which will also affect the purification effect of medicinal materials. How else to say... Alchemists above alchemy master can't completely purify the effective components in the medicinal materials. They must add 30% more to the materials of a furnace of pills!

However, Lushan's control of the flame can be said to have really reached the level of arm and finger. Although he doesn't use his own true yuan fire, he can perfectly control the fire generated by the void only by virtue of his affinity and understanding of fire attribute elements!

And let the void flame burn completely according to his will, which is much more obedient than the true yuan fire, and he doesn't need to consume his own true yuan. Let alone the low-level pill that doesn't take too long to refine. Even if it's the pill that needs to be refined for several days and nights to succeed, he can completely avoid the ground fire, Just use the move of generating fire in the void!
