The entrance to the mountainous area of Shangliang City was still the same as last time, but Su Mi found that there was a strong fragrance of green grass around her.
After asking Lu Wenli, and Lu Wenli found several mutated orchids at the entrance to the mountainous area, he determined the source of the fragrance.
These mutant orchids are very strange. The fragrance does not come from the flowers, but from the roots.
Their roots penetrate deep into the ground and spread far away, coupled with heavy rain hitting the ground. So the fragrance spread, and even Jiu, who had a very sensitive sense of smell, couldn't determine the source of the fragrance.
"This orchid should be a type of orchid, but that's not necessarily true. Plants after the apocalypse have mutated and become all kinds of strange. I can't be particularly sure since Mr. Wang is not around."
While Su Mi dug the roots of the orchids, she secretly sent some of the orchids with roots into the space.
"Lao Lu, Lao Chen, Lao Ma, when you dig, just put a ball of soil at the root, and then put it on the head of the octopus monster."
"I understand, boss, why are you obsessed with plants like Mr. Wang?"
Su Mi glared at Ma Dexiang, "What do you know? Plants in the apocalypse are so precious! Do you always skip the classes that Mr. Zeng and Mr. Wang have at the base?"
Ma Dexiang blushed, rubbed the back of his head and explained, "Oh, boss, I'm a bad student. I get sleepy while reading and listening to lectures. Isn't it difficult for me to go to lectures?"
"Still quibbling! Learning this knowledge will help you improve your ability to survive in the apocalypse. Can it be the same?"
"That's right, don't you know the reason why the water in the Goose base is so clean is because there are many plants. The roots of the plants absorb those dirty things underground and filter the water. Otherwise, the people in the Goose base I have long suffered from skin diseases that cannot be cured."
"There are just a few types. We finally made a trip to the mountains, and there is this big octopus. Let's dig out more plants and plant them."
"Yes, there are a lot of medicinal herbs in this mountain. I was in a hurry last time, so I can pick some more medicinal herbs back this time."
Su Mi thought about it for a while and felt that what everyone said was good, "Let's do this. I will take Shanshan to find the mineral veins, and leave the octopus monster to everyone. Just let him put the plants you collected on his head."
"I'll go with you." Jiu quickly approached Su Mi and said.
"No, you have great strength. Help me find some rare trees and flowers." Although her space was opened, Su Mi felt that every time a new species entered the space, the aura would continue to grow.
Unlike before, the spiritual energy became constant after it reached a certain value. The current space is like a black hole where spiritual energy can grow infinitely. Su Mi even feels that if this continues, there will be more changes in the space, but at least she can't see it yet.
Qin Hao originally wanted to go with Su Mi, but Su Mi seemed to have already decided. Moreover, she has space at hand, so even if there is any danger, nothing will happen.
On the contrary, they can take advantage of the convenience of being in the mountains to add more plants to the base.
"Then be careful and let Big Mac and Xiaobai go with you."
Su Mi nodded and touched Xiao Bai's head, "Well, then you should be careful in everything." Su Mi patted Qian Shu's tentacles, "Qian Shu, you have to listen to Brother Jiu and Brother Qin Hao, do you understand?"
Qianshou sensibly rubbed Qin Hao and Jiu with two of its tentacles, and then made a "squeak" sound like a mouse.
"I know, Master."
Su Mi took Ge Shanshan towards the place with the weird magnetic field that she pointed out.
Xiaobai followed Su Mi, and Big Mac swooped into the bushes ahead to explore the way for Su Mi.
What Ge Shanshan was holding was a magnetic field detector that relied on natural gravity measurement. Su Mi was also very curious when she saw that she was holding something that looked like a compass.
"Shanshan, can this thing really detect different magnetic field positions? It seems very simple, and" Su Mi always felt that after the end of the world, the magnetic field of the entire Blue Star would be affected.
If Li Changtian hadn't transformed and expanded the communication signal in Linjiang City to have a certain degree of anti-interference, the magnetic field would have been chaotic no matter where they went.
"This detector was developed by the teacher and Dr. Li. It contains a satellite guidance chip with a super strong signal. It can also amplify the signal within a certain area, so I think it should not be interfered by too strong a magnetic field. .
Well, that's right there. "
Ge Shanshan stretched the detector in her hand forward.
"Mimi, the terrain here is the same as the surrounding environment, but the magnetic field is very strange. Look." As she spoke, Ge Shanshan took Su Mi one step forward, and then moved the detector in her hand in front of her.
"Moved?"
Su Mi looked at the compass-like detector. Three metal beads of different sizes, one black, one white, and one silver, were rotating and rising from the bottom of the detector, floating at the top of the detector.
"what is this?"
"These are three different metal gravity balls. They and the metal on the outer ring and inside of the detector have been handled by the teacher personally. The largest one represents the gravity detection on the blue star, and the inside of the smallest ball is It is hollow. If we are standing above a thousand meters above sea level, this hollow ball will react with the surrounding metal and roll to the position where the scale is 1."
Su Mi nodded in wonder, "So if the altitude is two thousand meters, it will stay at position 2?"
"Yes. Coupled with the largest gravity ball, if it is at an altitude of one thousand meters, the gravity ball will roll to the position of -1."
"In other words, the largest ball and the smallest ball represent gravity and altitude, so where is the other one?"
Ge Shanshan frowned, "That ball is used to test the force of magnetic fields. The ball is doped with some metals with special magnetism. If the surrounding magnetic field changes, the micro-battery in the ball will release current to make it rotate. stand up.
Look at the scale on the outer ring. "
"x, y? Spool?"
"It's a bit complicated to say, but it's just like solving an equation in mathematics using a line axis. When it falls at a certain intersecting position on the xy line axis, it represents the value of the magnetic field at that time.
But now"
Su Mi also fell silent.
"But now, the three balls have deviated from their original orbits and are floating and rotating at high speed, so neither altitude, gravity, nor magnetic field can be detected?"
Ge Shanshan nodded deeply, "You can say that."
So she pulled Su Mi back to their original position and handed her the detector again.
"Look, just one step away, the detector data returned to normal."
Su Mi suddenly felt that this detector was magical. Obviously, as long as they take a step, the magnetic field in front of them will change. The changes in the magnetic field may be related to the jade veins.
"Shanshan, can you give me your detector temporarily?"
Ge Shanshan handed the detector to Su Mi without hesitation.
