Rowling looked at the concrete with curiosity, as did Chen He.

"Now let's test the strength of this concrete," Ye Feng said to Luo Qing.

Luo Qing immediately called over several civilians to tap and hammer the concrete, comparing it with the rock next to it.

Half an hour passed before we knew it, and the test results were finally in.

Although Luo Qing's testing method was very crude and unrigorous, it was still possible to draw a general conclusion.

Ye Feng was very satisfied with the test results.

This concrete is stronger than ordinary rock, and its toughness and other properties are also superior to those of rock.

"That's fine, no problem. From now on, we'll produce cement according to this ratio. From now on, cement will be the main building material for our Xinluo City," Ye Feng said.

"Yes, Ancestor!"

Luo Qing said with her chest out and head held high, her expression full of pride.

Ye Feng took out a handkerchief and wiped the cement dust off Luo Qing's face, saying, "You are a very competent director of the Construction Department. I am proud of you."

Upon hearing Ye Feng's words, Luo Qing was slightly taken aback.

Then she burst into tears of joy and said emotionally, "Don't worry, Ancestor, I will work even harder and will never disgrace the honor of our Luo family!"

But just then, a loud bang came from afar.

Ye Feng's expression changed slightly, and Luo Lin and Luo Qing were clearly startled by the sudden loud noise.

"What happened?" Night Wind asked.

"It seems to be coming from the blacksmith's workshop... Could it be that the furnace exploded?" Luo Qing said.

"Go and take a look quickly."

After saying that, Ye Feng strode towards the blacksmith's workshop.

Luo Lin, Luo Qing, and Chen He immediately followed.

Rowling then turned to the civilians and said, "Don't slack off, all of you, produce cement with all your might!"

"Yes, Miss!"

The common people all agreed in unison.

Before long, Ye Feng, Luo Lin, and Luo Qing arrived at the blacksmith's workshop together.

Many commoners were peeking into the blacksmith's workshop, where a terrible scene unfolded.

The blacksmith's only furnace exploded.

Broken pieces of iron were scattered all over the ground.

Several blacksmiths lay on the ground, groaning in pain, unable to move, with blood flowing everywhere.

Fortunately, they were all only injured and did not die.

But the blacksmiths all looked desperate; in their eyes, their lives were over.

After all, they were just commoners and serfs at the very bottom of society, and the city lord could not possibly spend a lot of money to hire pharmacists and alchemists to treat them.

But this is just their own wishful thinking.

After Ye Feng arrived, he inspected the scene and then took out several pills and handed them to Luo Lin.

"Give them these pills," Ye Feng said.

"Ancestor, should we really give them the elixir?" Rowling asked.

"Nonsense," Ye Feng said irritably.

Rowling originally wanted to remind Nightwind that the value of these few elixirs far exceeded that of these blacksmiths.

With these few elixirs, you can exchange them for a large number of blacksmiths in the capital.

But upon hearing Ye Feng's words, Rowling shut her mouth and said nothing more, lest she displease Ye Feng, an ancestor from seven hundred years ago.

After Rowling gave the seriously injured blacksmiths the pills, their wounds immediately began to close and stopped bleeding.

This scene amazed and shocked the common people who had gathered at the entrance of the blacksmith's workshop.

"What...what kind of miraculous elixir is that? It's amazing!"

"This elixir must be extraordinary!"

"Nonsense, those are elixirs! Elixirs are incomparable to ordinary medicines!"

"I can't believe my eyes! The city lord actually gave us commoners such a precious elixir!"

"We've met a wonderful city lord!"

The onlookers all looked at Ye Feng with reverence and even fanaticism.

Although it was the blacksmiths who were lying on the ground and seriously injured who took the pills, not the people who were watching at the door.

But they are all commoners. If Ye Feng can give elixirs to blacksmiths who are commoners, then Ye Feng will naturally not stand idly by if something happens to them in the future.

Of course they understand this principle!

At this moment, the blacksmiths had recovered to about 70-80%.

Although they still have wounds, these wounds are fading at a visible rate and are expected to disappear completely in a few days, leaving no trace.

Knowing that the city lord had saved their lives, the blacksmiths immediately knelt down and verbally thanked Ye Feng as soon as they got up.

"Everyone, stand up and speak," Ye Feng said.

"Yes, Lord City Lord."

The blacksmiths got up from the ground, and the leader bowed and scraped as he approached Ye Feng.

"Are you the manager of the blacksmith's workshop?" Night Wind asked.

"Yes, I am the manager here, and I am in charge of everything here," the manager said, his voice filled with trepidation.

"Why did the stove explode?" Night Wind asked again.

The manager hurriedly said, "It's my fault, I deserve to die! Miss Luo Qing told me to build the blacksmith's workshop as quickly as possible and put it into production immediately, so I was too anxious and didn't pay attention... and this happened."

“Ancestor, there’s a problem with the design of this furnace,” Luo Qing suddenly said while inspecting the iron smelting furnace.

Night Breeze walked over and asked, "What's the problem?"

Luo Qing explained it once, and Ye Feng asked, "I didn't expect you to know about this. You surprise me."

Luo Qing immediately revealed a smug expression.

Luo Lin sighed, "Qing'er is just too lazy to study. If she could focus on cultivation, she might already be a True Essence Realm martial artist."

"This is not a matter of being ignorant and incompetent."

Night Breeze shook his head and said very seriously, "What Luo Qing has researched will be of great help to the management and construction of the territory. I dare say that if Luo Yun City had not been attacked by the Crimson Tail Beast, then in a dozen or even a few years, Qing'er, the city lord, would have been able to make Luo Yun City prosperous."

"As the city lord, martial arts strength is essential, but it's not everything. Making the city prosperous isn't something that can be achieved simply by being strong."

Rowling wore a thoughtful expression, as if pondering the meaning behind Nightwind's words.

Night Breeze smiled and said to Rowling, "Now that the cement has been successfully fired, the next task is to rebuild the blacksmith's workshop. This is your new task, and I hope you can bring me another surprise."

"Yes, Ancestor." Luo Qing nodded emphatically.

Suddenly, the night wind revealed a mysterious smile and said, "I suddenly have an idea."

"What idea?" Luo Qing asked curiously.

"Do you still remember those Qi cultivation research notes?" Ye Feng asked.
