The greenhouse cave in Beifeng City grows not only the staple foods for the residents of the Great Graveyard but also a proportion of economic crops.

Under Dave's guidance, Luo Yan, riding Alakdo, proceeded slowly along the main path of the planting area, his dark cloak gently rising and falling with the legs of Luo Teng's spider mount.

After passing through a stalactite cave, the group quickly arrived at a region distinct from the previous one.

Here grew a mass of quartz stone, emitting a faint, dark green ethereal light from within the murky crystals.

"... This is an unfinished magic crystal mine. Since we discovered it after the area had been designated as a planting zone, and the surrounding areas have been transformed into greenhouse caves, mining became quite difficult. Therefore, after discussion, your servants decided to abandon mining and instead directly connect the magic conductor to this magic crystal mine."

Stopping before the entrance of a cave, Dave, draped in a robe, reported respectfully to Lord Demon King.

Upon hearing his report, Luo Yan showed an approving expression and nodded with a smile.

"Excellent, that's a brilliant idea."

Oke's Magic Workshop has already figured out the knack of concentrating and transmitting magic power through the magic conductor, and unlike coal mines, magic crystals do not require ignition to release energy. Thus, directly inscribing the Netherworld Language that releases magic power on the magic crystal mine is also an efficient utilization method, which mainly requires some effort in the design of the magic array.

Given that the greenhouse cave is next to this magic crystal mine, the work should not be very difficult, and the magic power loss is completely within an acceptable range.

Seeing the approving expression on Lord Demon King's face, Dave respectfully continued.

"Because your servants adopted the method of directly activating the natural magic power reserves in the magic crystal mine through a magic array, the magic power concentration in this cave is much higher than in other planting areas. According to Mr. Miranda's suggestion, we have isolated this magic-rich area and turned it into a special crop planting area."

"Unlike the regions where food is planted, this area mainly grows some rare species transplanted from the south coast of the Vortex Sea or the New Continent, which demand extremely stringent environmental conditions. However, the value of the finished products is correspondingly high... They are all precious magic potion materials and alchemy substances."

Luo Yan asked with keen interest.

"And the seeds? Where did you get them from?"

Dave replied respectfully.

"Thanks to your alliance with Catastrophe Castle, they had a number of these items on hand, and since they are not skilled at farming, we bought them from them."

Upon hearing Dave's response, Luo Yan immediately guessed the situation.

Given the nature of the Hell Dwarves, they likely seized the seeds from human trade caravans during their raids down the mountains.

From the northeast coast of the Vortex Sea to the northern wilderness of the Aus Continent lies an important trade route. Merchants from Ryan Kingdom would buy magic materials and seeds from the southern Vortex Sea and the New Continent at the Thunder City port, transporting them through Ryan Kingdom and Rhode Kingdom to the Imperial Academic State inland.

On this journey, they pass through the corridor in the southwestern offshoot of the Ten Thousand Ridges Mountain Range about the River Valley, where Shattered Rock Peak, home to Catastrophe Castle, is located southwest, connecting the River Valley and the Twilight Forest.

"In the hands of these Hell Dwarves, there are likely not only rare magic materials and seeds but also plenty of alchemical tools and magic guidebooks from the Academic State."

Luo Yan couldn't help but ponder this in his mind, contemplating how to lure the Hell Dwarves to his domain to fence their goods through trade means.

While he doesn't particularly need those trinkets, Players would probably still be interested in those flashy items.

The timing is perfect as both sides have close cooperation in food and mineral trade, so this matter should be feasible.

Thinking along these lines, Luo Yan dismounted from Alakdo and walked over to a nearby cave.

The plants grown here are a herb called Blazing Flame Flower, which primarily grows on volcano craters or deserts outside Brass Pass, and only blooms in magic-rich regions. Oil extracted from its petals, combined with Purgatory Scorpion venom sac powder and three drops of Dragon Turtle bile, can be synthesized into a potion that enhances fire resistance.

Due to Hell's unique geographical environment, this vividly colored and long-lasting flower is very popular in Hell, and it's said that some demons carry it as a "Lucky Flower" to pray for good fortune.

Luo Yan bent down, carefully examining these delicate flowers, feeling the slight fire element fluctuations from beneath the fluorescent leaves.

The magic conductor buried in the soil provided a fire element environment for the plant roots.

Not only that, but he also smelled a faint sulfur aroma, seemingly emanating from the fertilizer spread on the soil.

Luo Yan extended his hand to gently touch a leaf, quickly triggering a magic-like ripple spreading around.

At this moment, a skeleton soldier lurking in the flower bushes slowly rose, apparently sensing some movement, its skull flickering with nether fires as it approached Luo Yan.

Its skeleton made faint cracking sounds like a puppet pulled by strings, holding a bone knife in its hand.

Sarah wordlessly grasped the hilt of her sword at her waist. Although she knew this thing couldn't harm Lord Demon King, she wouldn't give any impudent fool a chance to offend him.
