Lin Yuan only heard Master Hong Shen, who was demonstrating at this time, speaking with great interest.

"Old Hu's underground space is too shallow at 30 meters. We need to dig at least 300 meters."

"And the underground space must be large enough and solid! It would be best if a diamond-level spiritual creature rolling around underground would not have any impact on the underground space."

Master Hong Shen was already sloppy, and no one knew what he was busy with during this period of time and why he hadn't taken a shower.

This made the beard on Master Hong Shen's chin clump together.

As Master Hong Shen spoke, all the saliva that came out of his mouth stuck to his messy beard.

His two hands were almost so excited that he wanted to snatch the pen from Hu Quan's hand to help him draw the design of the underground space.

After listening to Master Hong Shen's words, Hu Quan felt as if firecrackers were going off in his head.

Somehow, Hu Quan felt a surge of anger in his heart, and he slammed the pen in his hand on the table and said angrily.

"Old Man Hong, the underground space is thirty meters deep enough. Do you know that you want to dig three hundred meters?"

"The soil layer of the 30-meter underground space already contains a lot of water vapor. If we dig one more meter down, all the water in the soil layer will seep out."

"Are you planning to build an underground space for cultivating spiritual creatures or to build an underground reservoir to store groundwater?"

"It is not impossible to dig the underground space to 300 meters, but the underground space must be reinforced with platinum-grade metal spiritual material rock-penetrating steel on all sides."

"Even if you are not a spiritual craftsman, as a four-star creator you should know the price of the platinum-grade metal spiritual material rock-penetrating steel."

"Without the rock-penetrating steel to block underground moisture, the entire underground space will be extremely damp, not to mention a diamond-level spiritual creature rolling around in it."

"Even if a gold-level earth-type spirit creature releases elemental skills, the underground space cannot hold up."

"The problem of oxygen in the deep underground space is easy to solve. Most spiritual objects that can release oxygen can replenish the oxygen needed in the underground space, but what about light?"

"Even if you open a few windows above the underground space, the sunlight can only illuminate a depth of 100 meters at most, but the underground space below 200 meters is still pitch dark."

As a five-star craftsman, Master Hu Quan’s job is to draw design drawings, which is also what he is proud of.

Hu Quan has always hated outsiders pointing fingers at him when he is drawing designs.

Like when Hu Quan and Lin Yuan discussed the construction of Qianjiao Lake before, Lin Yuan's opinions and requirements made Hu Quan feel refreshed.

Even the design has given rise to different inspirations.

Moreover, when discussing the construction of Qianjiao Lake with Lin Yuan, Lin Yuan's proposals were often accompanied by the outpouring of a large amount of resources.

This allows Hu Quan to avoid having to over-calculate material costs, which would affect the exquisiteness of the design itself.

Therefore, Hu Quan was very willing to discuss the construction of the manor with Lin Yuan.

However, at this time, every word Master Hong Shen said could be regarded as an unrealistic and unreasonable demand in Hu Quan's view.

If Master Hong Shen had not said that Lin Yuan had approved the construction of the underground space, Hu Quan would never have been here to draw the design under Master Hong Shen's command.

When Master Hong Shen heard Hu Quan's question, he seemed not to hear the anger in Hu Quan's words at all, and spoke directly without any concern.

“I have talked to the young master before about the sunlight problem in the underground space, and the young master said that he can solve the sunlight problem.

After hearing what Master Hong Shen said, Hu Quan felt that it would be impossible to get any results from talking to Master Hong Shen about the construction of underground space, so he simply stood up and spoke.

"When Lin Yuan comes back, I will ask him directly how the underground space should be built."

Hu Quan stood up and immediately saw Lin Yuan who had just stepped into the door.

"Lin Yuan, you're 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 spoke to Lin Yuan.

"Master, I have already bought that forest."

"I found that the soil under the forest is very fertile, and I also found a nest of earthworms in the land."

"These earthworms can evolve into earthworms after special breeding."

When Lin Yuan heard what Master Hong Shen said, he immediately understood why Master Hong Shen wanted to dig the underground space to below three hundred meters.

Because the gravitational force and gravity attached to the environment below 300 meters underground are important conditions for inducing burrowing earthworms to evolve into soil-humping earthworms.

With earthworms, you can have a large amount of high-humus soil.

Lin Yuan also asked Master Hong Shen to conduct a detailed study on the Golden Lotus Plant, and Master Hong Shen and Congming came to the same conclusion.

There is no wrong version in the 1619 book forum!

That is, if you want the sub-plants of the Golden Lotus plant to grow quickly, you need a large amount of soil high in humus.

Otherwise, before the new plant has a chance to grow up, the nutrients originally in the daughter plant will be absorbed by the mother plant of the Golden Lotus.

This causes the seedlings to wither.

Lin Yuan nodded and said to Master Hong Shen.

"That's a good idea. I'll leave it to you to cultivate and evolve the earthworms into 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 tunnel from the manor to the Shenmu Federation in the underground space."

Hu Quan didn't quite understand the first half of Lin Yuan's words. Lin Yuan wouldn't dig the underground space to 300 meters below the ground just to cultivate earthworms, right? How much does the humus soil produced by earthworms cost? Even if a lot of resources were consumed, it wouldn't be more than the resources consumed by digging 300 meters underground.

When Hu Quan heard Lin Yuan say that he wanted to open a space corridor from the manor to some federation, Hu Quan immediately realized the strategic significance of the underground space.

Under such strategic significance, it is still necessary to dig a three-hundred-meter-deep underground space.

When Master Hong Shen, who was standing by, heard Lin Yuan's words, a look of surprise flashed in his eyes.

Master Hong Shen had not been at the manor for long and did not live there on weekdays.

Although Master Hong Shen gets along well with everyone on weekdays, 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 talked about digging 300 meters of underground space, he did not tell Hu Quan about Lin Yuan's plan to cultivate a large number of Golden Lotus plants.

The Golden Lotus Plant, a spiritual object that can drive any creator crazy, is extremely precious in the eyes of Master Hong Shen.

In addition to the reason of the earthworms, Master Hong Shen felt that digging three hundred meters underground would not only increase the confidentiality of the Golden Lotus Beads.

At the same time, you don't need to buy humus soil in the future when cultivating golden lotus beads.

However, Master Hong Shen did not expect that Lin Yuan would actually open a space corridor in the manor to connect to the Shenmu Federation.

First update.
