[A/N: I could directly just show you the numbers but I thought it would be better if I used this chance to give you guys an idea about a few other things at the same time. Like how much mana a trainee knight has, how much his people changed, etc.]

[Calculating the raw mana pool per run]

1,000 F rank knights × 10 mana = 10,000 mana

4,000 Soldiers in training × 6 mana = 24,000 mana

5,000 New soldiers × 2.5 mana = 12,500 mana

8,000 Regular citizens × 2.1 mana = 16,800 mana

Total raw mana per run: 63,300 mana

[Calculate the daily mana generation]

63,300 mana × 2 = 126,600 raw mana generated per day.

Adrian looked at it and nodded. This was because the people did go to the dungeon twice a day.

’Well, I don’t get all the mana. 1 out of 10 mana is used to make ingots so take that into consideration too.’

[Factoring in the 10% cost for the ingots]

126,600 × 0.10 = 12,660 mana

126,600 - 12,660 = 113,940 mana saved by the dungeon per day.

[Calculating the 30 day total]

113,940 net mana × 30 days = 3,418,200 mana.

Adrian stared at the screen before realising that he was being dumb again. It was almost like he had gotten the idiot disease. Why was he calculating all this when he could just check his dungeon status?

Feeling annoyed with himself, Adrian opened up his dungeon status and asked for the total mana he had in the form of mana crystals.

[Current Mana: 1,601,742]

’Okay... time to put all this mana to use now.’ he thought, ’I will use two hundred and fifty thousand mana to make a new room.’

He mentally commanded the dungeon to spend the mana.

A new room formed beside the one he was currently in, and Adrian walked towards it. The wall split up for him and he looked at the room in front.

It was just an empty room, but Adrian looked at his system screen and used Unique Biomes skill. A list of multiple biomes came up and he picked the one that cost him no mana. It was basically just a farmland with short grass, which would be perfect for grazing.

The 250,000 mana investment gave him 25,000 acres of land.

Next, he used his Temporal Overdrive perk.

He applied a time doubling effect to the entire twenty five thousand acre biome.

Because the basic level of time acceleration simply doubled the speed of time, the mana cost directly matched the territorial expansion cost. He paid another two hundred and fifty thousand mana points for this.

Time inside this specific dungeon room now flowed twice as fast as the real world outside.

In total, he had just spent half a million mana points in two minutes.

Now he needed to feed his future cows.

He opened his spatial storage and dumped out a massive pile of different grasses, plant seeds, and a lot of random plants. He had spent the last month secretly collecting all of these diverse plant breeds from Duke Silas and Marquis Draven while he was waiting for the animals to arrive.

’System.’ Adrian thought. ’Analyze these plants. I need you to engineer a completely new breed of grass.’

He then started listing his requirements.

’It need to be incredibly nutrient dense. It needs to be easily digestible for my new cows and it must contain a massive amount of caloric energy and provide a completely full, balanced diet for the livestock. The more perfectly balanced the nutritional profile is, the better.’

He continued, giving more requirements.

’It also needs to be extremely fast growing and it must be a perennial crop that does not require replanting. As long as the main stalk and the root system remain buried in the dirt, the grass needs to infinitely regrow itself after being cut. As long as the bottom inch or two of the stalk survives above the soil, it must regenerate.’

The system processed the data. Because plants were infinitely less complex than making chimeras, the simulation did not take three hours.

It took exactly ten seconds.

The blueprint for the perfect super grass was ready and Adrian looked at the screen.

It was a towering, thick plant. The system recommended a perfect harvest length of exactly three meters tall. The base stalk was incredibly thick, roughly the thickness of a tennis ball and it had multiple long, broad leaves that sprouted outward from the central shoot.

The growth cycle was perfectly optimized. The very first initial growth cycle from a planted seed took exactly one month to reach the three meter height. But once the grass was established and cut back to the stalk, the regrowth phase was incredibly fast. It only took seven days for the grass to completely regenerate back to its three meter height.

The system included a warning note too.

The grass could technically grow taller than three meters. But after the seven day mark, the plant began developing complex, hardened proteins that made it significantly harder for cows to digest. So the perfect time to harvest the grass was exactly at the seven day limit.

Adrian grinned. ’That is perfectly fine. I have a massive amount of land to work with so I can easily cycle the grazing schedules.’

He did not manually divide the twenty five thousand acres himself. He asked the system to calculate the perfect spatial ratio.

He needed to balance the amount of land required to grow the super grass against the amount of land the cows needed to live comfortably. He did not want his premium livestock crammed into tiny, miserable boxes like a lot of places did back on Earth.

Adrian used the system to pick the most optimal layout where everything worked flawlessly to ensure the cows got enough feed and plenty of roaming space.

The system finalized the blueprints and the twenty five thousand acres were split into two distinct zones. Exactly five thousand acres were dedicated entirely to growing the super grass. The remaining twenty thousand acres were designated as the open grazing fields for the cows.
