"Of course I remember," Luo Qing nodded repeatedly.

“There’s something up there called a Net-Style Spirit Gathering Array, or Spirit Net for short. Try using it in the blacksmith’s workshop. If you succeed, it will be a groundbreaking innovation!” Ye Feng said with a smile.

Luo Qing's eyes immediately sparkled.

Luo Qing remembered the net-like spirit-gathering array very clearly. It was a kind of array that cleverly connected several spirit-gathering arrays in parallel, which could spontaneously gather the spiritual energy between heaven and earth.

Moreover, compared to traditional spirit-gathering arrays, the net-type spirit-gathering array consumes far fewer spirit stones, almost to the point of being negligible.

Because the net-type spirit-gathering array can use spiritual artifacts to maintain its operation after gathering the spiritual energy of heaven and earth, which is an effect that traditional spirit-gathering arrays cannot achieve.

However, this does not mean that once the net-like spirit-gathering array is successfully set up, it can continue to operate indefinitely.

There is no such thing as a perpetual motion machine in this world, not even in the Lingluo Great World.

Because the materials used in the Spirit Gathering Array have a limited lifespan, Luo Qing did not test them and did not know how long the materials that make up the array could operate.

But this time is certainly not eternal.

Regardless, the net-type spirit-gathering array is indeed superior to the traditional spirit-gathering array.

So if this idea really succeeds, it will indeed be a great feat, even epoch-making!

"Ancestor, I will do my best!" Luo Qing said earnestly.

"come on."

Ye Feng said with a smile, and patted Luo Qing's head.

Rowling said from the side, "Grandpa, don't spoil her too much. It wouldn't be good if you spoiled her too much."

The blacksmith's workshop has resumed operations, and the cement firing is also being carried out by working overtime.

Cement was produced in a steady stream and transported to the camp in truckloads, so the camp began to build concrete houses.

The commoners and serfs who were building the project were very curious about cement.

At first, they didn't know how to use this thing.

However, after the construction team members sent by Luo Qing gave an on-site explanation and demonstration, these people immediately mastered the skills of using cement for construction.

After all, this thing is not difficult to do and is very easy to operate.

So, in just four or five days, three-story concrete buildings had already appeared in the camp.

Rowling was quite amazed by these small buildings.

Before this, houses were at most two stories high, three stories were rare, and four stories were even less common.

Commoners and serfs simply could not afford to live in houses with more than one floor.

Two- or even three-story houses have always been a symbol of status and wealth.

This is, of course, due to the extremely outdated technology used in building houses in the Lingluo Great World.

Now that cement has been available, the technology for building houses has been greatly improved, and the efficiency has also been greatly increased. As a result, the commoners and serfs of Silla City are now able to live in three-story houses.

"Surprised? This is only because steel production is currently insufficient, making it impossible to manufacture steel bars on a large scale. If steel bars were added to concrete, let alone three-story buildings, even more than ten-story buildings would be no problem at all," Ye Feng said with a smile.

"Rebar?" Rowling asked curiously.

"It's a kind of steel that's forged into a rod about the thickness of a finger," Night Wind explained.

"Oh, I see." Rowling looked enlightened.

Then, Rowling looked at Ye Feng with admiration and said, "I never expected that you, Ancestor, would know so much strange and wonderful knowledge."

"I haven't wasted these seven hundred years. When I'm bored, I think, and over time I naturally come up with a lot of ideas," Ye Feng said with a chuckle.

Night Wind was obviously lying through his teeth, but Rowling didn't doubt it.

"How's the situation at the blacksmith's workshop?" Ye Feng asked.

"It's still under construction. It seems that your idea of ​​adding the net-like spirit-gathering array to the blacksmith's furnace has stumped Qing'er," Luo Lin said with a smile.

“It’s certainly not an easy task to succeed,” Night Wind said.

Rowling then added, "Why hasn't that brat Zijing come back yet? Could she have really absconded with the money?"

"Perhaps we've run into some trouble?" Night Wind said.

Just as Rowling was about to say something, the maid Luo Xiaotong ran in.

"Grandfather, Madam, Miss Zijing has returned, and she brought back another... another..."

Rowling asked, "What did you bring back?"

“A beggar!” Luo Xiaotong said.

Rowling was stunned.

Didn't Zijing go to invite a spiritual medicine master? How come she brought back a beggar?

Night Breeze also showed a puzzled expression.

As they spoke, Zijing had already appeared in the distance.

Behind Zijing was a disheveled old man. The old man looked to be in his sixties or seventies, with white hair and beard. His robe was dirty and tattered, and there was even some mud on his trousers.

It has to be said that this old man does look rather unsavory, like a beggar begging on the street.

But Ye Feng's eyes lit up.

Because this old man's attire and appearance had a certain air of a wise and unassuming person!

Could it be that Zijing really knows a reclusive herbalist, and a master at that?

"Let's go take a look."

Night Breeze and Rowling emerged from the tent together and strode towards the Bauhinia.

Upon seeing Ye Feng, Zi Jing immediately broke into a bright smile and ran over excitedly.

"Old Deng, did you see that? I brought the man to you!"

Upon hearing the words "Old Deng," Rowling immediately glared at Zijing.

Ye Feng, disregarding Zi Jing's offense, immediately asked, "Is this the apothecary you invited? What is his name?"

“His name is Xu Ping’an, you can just call him Old Xu,” Zijing said with a smile.

“That won’t do, that’s too impolite,” Ye Feng said, shaking his head.

As soon as Ye Feng finished speaking, Xu Ping'an walked over and stood in front of Ye Feng and Luo Lin.

"Which one of you is the lord of Silla City?" Xu Ping'an asked with a smile.

“That’s me,” Night Wind said.

Xu Ping'an looked surprised and sized up Ye Feng a few times before saying, "That's not right, is it? This little girl Zijing clearly told me that the city lord of Xinluo City is an old guy who has lived for over seven hundred years..."

"A martial artist's age cannot be judged by his appearance, can't it?" Ye Feng said with a smile.

Then Ye Feng straightened his expression and said politely, "Welcome, Boss Xu. I hope your alchemy skills can bring prosperity to our Xinluo City."

Almost simultaneously, Xu Pingan said, "Lord City Lord, rest assured, I will do my utmost to help you appraise the antiques..."

Appraising antiques?

What the hell is this?

Ye Feng was slightly taken aback and asked, "Did I hear that right? Did you just say you were appraising antiques?"
