With a thermometer to measure the atmospheric pressure value, the latitude and longitude are also easy to do, Ye Zhi once brought back a mineral map of the wind and thunder world, remove the mineral markers made on it, just look at the whole This is a delicate map of the wind and sound world, copy the map as it is, and mark the latitude and longitude lines on it, Ye Zhi took Lu Xiaoman to write a piece of paper full of atmospheric pressure measurement requirements and set off to the north sea, and came back three days later, bringing the standard atmospheric pressure value of the wind and the sound world obtained after repeated measurement and calculation.

At that time, Lu Xiaoman had already obtained a ring from his master Mu Yan Zhenjun, which was full of waste spirit stones, and what she had to do next was a tedious experiment of extracting spiritual energy from waste spirit stones, after putting it into actual production, she could not use Tianhuo as a heat source, she had to find a substitute, and the waste spirit stones themselves contained various impurities, and the gas composition that overflowed after the stone was burned was complex, and she had to find a way to remove impurities step by step, until she finally got pure spiritual energy.

In order to store the pure aura that is not easy to obtain, the design and trial production of gas cylinders should be put on the agenda, and the necessary barometers of gas cylinders should also be designed simultaneously, and suitable materials should be found to make samples.

Thousands of threads are all pressed on Lu Xiaoman alone, the full set of production lines for the artificial preparation of aura have to be drawn by her to draw the process flow chart and production line design drawing, and then to know what mechanical equipment is needed for the entire production line, Lu Xiaoman then drew drawings one by one, from the general drawing to the assembly to the parts drawing, the drawings of the three major steps are drawn by herself, fortunately, she ate this bowl of rice in her previous life, this is her strength, hand-drawn drawings and calculations are her basic skills, there is no computer, calculator or even hand-cranked calculator, only calculation chips and pens, Lu Xiaoman buried herself in hard calculations, and the used scratch paper was piled up on the ground, and all the white paper that could not be used up in the rune factory was emptied by her.

Busy like this in private, during the day, Lu Xiaoman still has to do everything as usual, he can't slack off in the morning and evening, the senior brother of the Innocent Sword Monarch hasn't left yet, he dares to be lazy and want to be taken out and spanked, and the days of class have to go as usual, and the assigned homework must be completed on time, but the news of her emptying the existing white paper in the rune material workshop has been spread, which provoked Zhu Qi to ask, but Lu Xiaoman vaguely passed, although Zhu Qi felt strange but did not ask again, white paper is the inevitable product of learning to make rune paper, something that anyone can take for free, It's a bit surprising that Lu Xiaoman has all been emptied, but if you ask a lot of questions for a blank sheet of paper, it seems stingy.

After Mu Yan Zhenjun and Feiyang Zhenjun heard about this from other people's mouths, they had a little association in their hearts, the whole waste spirit stone of the ring must be related, although those white paper are not very good, it is still okay to write and draw on calculus paper.

Busy and busy, Lu Xiaoman also participated in the two small exams of the Fu Gong class on time, and lived up to expectations and got two excellent armors, every time she finished the exam, her paper would be applied for public by others, posted on the outer wall of the Fu Feng Lecture Hall, and every question was answered perfectly, especially the Fu Dao theory in the primary class was even more solid and profound, and even inspired the four foundation building disciples to have an epiphany on the spot, and the two of them were promoted to the next level, and the master of Fu Feng Peak, Ming Yi Zhenjun, gave Lu Xiaoman a heavy reward on the same day.

Such a spectacle spread throughout the sect in one day, and the next day it spread to the fang market outside.

Do you still remember Lu Xiaoman, a disciple of the Heaven Seeking Sect who wrote out the time rewind talisman array during the Chinese New Year? The volume she writes can help people with epiphany and small promotions, and she is the best genius of Fu Dao, and she is eleven years old this year.
