It was undoubtedly a wise choice to accept Ophelia as a slave girl.

"Do you have any ideas for the next phase of the product?"

Chen Xuan clasped his hands in front of his chest and took the initiative to ask her opinion.

Seeing that the half-elf eldest lady had already had a draft, she lowered her head and thought for a moment before she said seriously.

"It takes a while to sell bicycles."

"I've tried it many times, and there's no doubt about its practicality, and there's still potential for the future..."

Hearing this, Chen Xuan couldn't help but raise his hand and asked a new question.

"You say, the West End Blacksmiths Guild bought the first bike."

"Is it possible that the other party will launch a replica?"

Ophelia shook her head decisively.

"It's hard!"

"It's not that the Blacksmiths Guild can't make similar vehicles."

"Those ingenious iron furnace dwarves can smash ingots into anything."

"But the problem is the cost!"

"The frame of the bike you brought is very strong, the steel wires inside the hub are tough, the outer leather is extremely hard-wearing, and even the technique of inflating and sealing is quite clever."

"The blacksmiths' guild wanted to imitate it, and if it used black iron, it would definitely cost more than 450 crowns, and if it was made of wood, the durability would be greatly reduced."

"As for the soft leather outside the wheel, it can only be replaced by animal skin or monster skin, and the cost is not low."

"In other words, even if it is a real imitation, there is no competitiveness at all."

Ophelia is well-organized and has a keen instinct for the product.

Chen Xuan bowed his head slightly, indicating that he understood.

"And what about the news I asked you to inquire about?"

After talking about business, it's time to talk about the secret door.

I saw that the smile on Ophelia's face retracted, revealing a solemn expression.

"Master, I have consulted many books and guild records related to monsters, and finally found a record about the secret passage!"

"The so-called secret passage is a kind of joint ceremony!"

"It can make several monster caves within a certain area resonate continuously."

"Every resonance point is a secret doorway!"

"For the duration of the passage, the restriction on the outpouring of monsters from the cave will be lifted."

"This method can make the monster cave gather a large number of monsters in a short period of time."

"In addition, multiple secret passages can also jointly open up high-level passages to summon those terrifying monsters to descend."

This explanation made Chen Xuan immediately understand the motive of the monster!

The so-called secret passage is nothing more than a ritual that can "explode" a large number of troops in a short period of time.

You must know that the number of cave monsters that gush out of each Naroa day is limited, which can be understood as "refreshing".

But even if monsters pour out, they will soon be hunted by adventurers.

After all, monsters are full of treasures, and killing monsters is tantamount to making money.

This is a state of equilibrium that has developed over the centuries in most of Naroa.

In such a situation, it would be a fool's dream for the monsters to gather enough numbers to counterattack the town.

It's just that there will always be times when the balance is broken, just like powerful adventurers and mercenary groups can destroy the caves.

The monsters also have the means to set off a counteroffensive.

And the secret door passage is one of them.

It involves a ritual system unique to monsters, and it also requires tedious preparations.

Seeing her master's contemplative expression, Ophelia added softly.

"According to the information of the Adventurer's Guild, in the past two months of Naroya, the number of farms/farms/ranches/forest farms destroyed in Magtan City has reached 107, the number of registered adventurers has reached 2,797, the number of foreign mercenaries is unknown, the total number of town residents has died is about 6,000 or more, and there are a large number of livestock..."

"A team of veteran adventurers found that the monsters outside were more irritable than before, and the aggregation was more obvious."

"Combined with the clues you provided, it is indeed possible that those monster caves around are preparing unknown rituals!"

"By the way, this is a map of all the proven cave locations within a two-hundred-mile radius of Magtan City..."

It has to be said that Ophelia's ability in business and administration is far better than that of Kitten.

At her level, she will be brought to Lanxing, and as long as she receives education, she can be employed as a secretary.

Reaching out to take the parchment map, Chen Xuan frowned and nodded.

"I see, I'll take care of this."

"Do you want to inform the guild?"

"After all, the safety of Magdam is at stake, and as long as the information is true, you will be rewarded with thousands of crowns."

Ophelia asked cautiously.

In this regard, Chen Xuan has his own ideas.

"Not yet..."

"At least not these Naroa days."

So saying, he took out a few Mithril coins, about a kilogram of Lang, and handed them into Ophelia's hands.

"With this money, several commissions were issued, appointing a ritual survey of some of the caves."

"Don't mention the Eya Forest, I'll go around that neighborhood!"

"There are so many demon caves around, and you can always come across a few that are building secret passages!"

"I'll probably be away for a few days, and I'll let you know by walkie-talkie the next time we meet."

Chen Xuan's orders were carried out in her soul contract.

Ophelia couldn't argue at all.

She grew up in Magdam City and felt a strong sense of belonging.

So instinctively I wanted to protect the town.

However, Chen Xuan obviously had her own considerations, and she could only choose to obey.

"I understand the master..."

……

After the two sides separated, Chen Xuan rode non-stop to the largest magic trading house in the Western District.

After some haggling, he bought a magic scroll that he had been interested in for a lot of 2,580 crowns—

- Third-Order Holy Light Magic Scroll [Caress of the Holy Spirit]!

Its effect is simple, it is to heal and restore limb trauma.

It can achieve the amazing effect of rebirth of a severed limb without leaving a noticeable scar!

Unfortunately, this magic has little effect on diseases and injuries to the organs.

Because in Naroa, the organs are involved in finer realms and require a higher level of healing magic.

In addition, he spent 2,700 kroner to buy a magic necklace called [Azure Guardian].

This necklace needs to be charged, and it can be used to enter magic essence, and it can also use magic seeds.

It unleashes the magic of the same name [Azure Guardian], which has a good defense against ranged attacks, as it cannot weaken the impact, so its defense in melee combat is limited.

In addition, Chen Xuan also bought more than a dozen of various spell scrolls, first and second order.

After such a trip, it actually cost six or seven kilograms.

When everything was ready, he and the kitten lady returned to Stink Mouse Alley.

When the two entered the shack, Rebecca's mother was vomiting with a wooden barrel.

Her condition has deteriorated so badly that she is in danger of dying soon.

Little Nick was sensibly erecting his bloated belly with hot water.

Chen Xuan glanced at it silently, and turned his head to look at Rebecca, who was full of sadness.

"I'm leaving two or three Naroa days this time."

"Wait until I get back."

"Yes, master..."

The kitten girl bowed her head and should go down.

After he finished speaking, he didn't stop, and directly launched the [cross-border].

With the singularity flashing, several dark coins fell to the ground.

"Dingding, ding, bell..."

A crisp sound echoed through the sour shacks.

Rebecca shuddered and picked up eight dark gold coins.

When he raised his head again, his red eyes were already full of tears.
