Lin Yuan only listened to Master Hong Shen, who was gesticulating at this moment, speaking with great interest.
"Lao Hu's underground space is 30 meters too shallow. We need to dig it to at least 300 meters."
"And the area of the underground space must be large enough and strong! It is best for diamond-level spiritual objects to roll underground and have no impact on the underground space at all."
Master Hong Shen is already sloppy, and he didn’t know what he was busy with during this period without taking a shower.
This caused the beard on Master Hong Shen's chin to stick together.
When Master Hong Shen spoke, the spittle that came out of his mouth stuck to his messy beard.
Both hands were so excited that they grabbed the pen from Hu Quan's hand and helped Hu Quan draw the design drawing of the underground space.
After listening to Master Hong Shen's words, Hu Quan felt as if firecrackers were set off in his head.
Somehow, a fire surged up in Hu Quan's heart. He slapped the pen in his hand on the table and said angrily.
"Old man Hong, the underground space is thirty meters deep enough. You have to dig three hundred meters, young master, do you know?"
"Thirty meters of underground soil already contains a lot of water vapor. If you dig another meter further, the water in the soil will seep out."
"Do you want to build an underground space for the cultivation of spiritual objects or do you want to build an underground reservoir to store groundwater!"
"It is not impossible to dig the underground space to three hundred meters, but the surrounding underground space must be paved and reinforced with platinum-grade metal spiritual material permeable steel."
"Even if you are not a spiritual craftsman, as a four-star builder you should know the price of the platinum-level metal spiritual material Permeable Rock Steel."
"Without the permeable steel to block the underground water, the entire underground space will be damp, let alone diamond-level spiritual beings wallowing in it."
"Even if a gold-level earth-type spiritual creature releases elemental skills, the underground space cannot hold it."
"The deep oxygen dug in the underground space is easy to solve. Most spiritual creatures that can release oxygen can replenish the oxygen needed in the underground space, but what about light?"
"Even if you open a few windows on the land above the underground space, when direct sunlight comes down, the light can reach a depth of 100 meters at most, but the underground space below 200 meters will still be invisible."
As a five-star spiritual craftsman, Master Hu Quan draws design drawings as his own job, and it is also something Hu Quan is proud of.
Hu Quan always hated having outsiders gesticulating while he was drawing design drawings.
Hu Quan and Lin Yuan discussed the construction of Qianjiao Lake before, and Lin Yuan's opinions and requirements made Hu Quan feel refreshed.
It even gave rise to different inspirations in design.
Moreover, when communicating with Lin Yuan about the construction of Qianjiao Lake, Lin Yuan's proposals are often accompanied by a large investment of resources.
This allows Hu Quan to not have to overly calculate the cost of materials, thereby affecting the exquisiteness of the design itself.
Therefore, Hu Quan is very willing to discuss the construction of the manor with Lin Yuan.
However, every word Master Hong Shen said at this time can be said to be unrealistic and unreasonable demands in Hu Quan's opinion.
If Master Hong Shen hadn't said that the construction of the underground space was approved by Lin Yuan, Hu Quan would not be here listening to Master Hong Shen's command to draw the design drawings.
When Master Hong Shen heard Hu Quan's rhetorical question, it seemed as if he didn't hear the anger in Hu Quan's words at all, and said it without caring.
"I told the young master before about the problem of sunlight in the underground space. The young master said that the young master can solve the problem of sunlight.
After hearing Master Hong Shen's words, Hu Quan felt that talking to Master Hong Shen about the construction of underground space could not achieve anything, so he simply stood up and said.
"When Lin Yuan comes back, I will ask him directly how to build the underground space."
Hu Quan stood up and immediately saw Lin Yuan who had just stepped through the door.
Hu Quan hurriedly said to Lin Yuan.
"Lin Yuan, you are back! Do you have any suggestions or plans for the underground space?"
Master Hong Shen turned around and saw Lin Yuan. His eyes suddenly lit up and he said to Lin Yuan.
"Master, I have already bought that piece of woods."
"I found that the soil under the forest was extremely fertile, and I also found a nest of earthworms in that land."
"These soil-boring earthworms can evolve into saprophytic earthworms after special cultivation."
When Lin Yuan heard Master Hong Shen's words, he immediately knew why Master Hong Shen wanted to dig the underground space below three hundred meters.
Because the gravity and gravity attached to the environment below 300 meters in the underground space are important conditions for inducing the evolution of soil-boring earthworms into saprophytic earthworms.
With saprophyte earthworms, you can have a large amount of soil with high humus content.
Golden Lotus Brocade Linyuan also asked Master Hong Shen to study it carefully, and Master Hong Shen and Clever came to the same conclusion.
That is to say, if you want the sub-plants from the Golden Lotus plant to grow quickly, you need a lot of soil with high humus content.
Otherwise, before the new plant has grown up, the new plant will be sucked out of the nutrients of the original plant by the mother plant.
This causes the sub-plants to wither.
Lin Yuan nodded to Master Hong Shen and said.
"This is a good thing. I will leave it to you to cultivate and evolve the soil-boring earthworms into saprophytic earthworms."
Then Lin Yuan looked at Hu Quan and said.
"Uncle Hu, the underground space really needs to be dug to 300 meters, because I want to open a space corridor from the manor to the Shenmu Federation in the underground space."
Hu Quan still didn't understand the first half of Lin Yuan's words. Lin Yuan wouldn't dig the underground space below three hundred meters just to cultivate saprophytic earthworms, would he?
How much does the humus soil produced by humus soil worms cost?
Even if it requires a lot of consumption, it will never be more than the resources consumed by digging three hundred meters of underground space.
And when Hu Quan heard Lin Yuan talk about opening a space corridor from the manor to some kind of federation, Hu Quan immediately understood the strategic significance of the underground space.
In such a strategic sense, it is still necessary to dig an underground space three hundred meters deep.
When Master Hong Shen on the side heard Lin Yuan's words, surprise flashed in his eyes.
Master Hong Shen has not been in the manor for a long time, and he does not live in the manor on weekdays.
Although Master Hong Shen usually gets along well with everyone, Master Hong Shen, who has just arrived at the manor, is not sure how deep the relationship between Hu Quan and Lin Yuan is.
Therefore, when Master Hong Shen said that he was digging a space three hundred meters underground, he did not tell Hu Quan about Lin Yuan's plan to cultivate a large number of golden lotus brocade plants.
The Golden Lotus Brocade, a spiritual object that can drive any creator crazy, is extremely precious in the eyes of Master Hong Shen.
Coupled with the reason for the slough earthworms, Master Hong Shen felt that digging 300 meters underground would not only increase the confidentiality of the Golden Lotus Pearl.
At the same time, you no longer need to buy humus soil in the process of cultivating golden lotus beads.
It's just that Master Hong Shen didn't expect that Lin Yuan would open a space tunnel in the manor that connected to the Shenmu Federation.
