His Highness the Madman gave in again today.

He was practically saying, "Are you sick in the head?"

"Are you kidding me?"

"Do you think I'm bored?"

Mo Sangyu also had a bad temper: "If you're being threatened with Yue'er, then just say whether you'll accept it or not."

Chu Canglan: "..."

He finally got rid of his burdens, but after only a few days of carefree living, he was asked to go back?

"Don't worry, I'm only letting you manage it temporarily. After Yue'er is reborn, I will let you leave. When you find Yue'er, it's up to you whether you want to come back or not. I will then train a suitable new city lord."

Chu Canglan's eyes flickered slightly, but he remained silent.

Mo Sangyu continued, "Didn't you say before that you wanted to come back after finding Yue'er? Now I'm giving you this chance, so don't take it for granted."

"Then do I, as the city lord, have any real power?"

certainly."

Feng Xingyu continued, "You have full authority over all affairs in Youdu City. We will not interfere, but will only listen to your reports periodically."

"You may keep half of the tax revenue from Youdu City for city construction and military expenses, and hand over the other half, but all expense details must be clearly traceable."

Chu Canglan fell silent.

The tent was quiet, with only the faint sound of tea boiling.

After a long while, he slowly spoke: "Alright, I'll temporarily take care of it for you, but in the future, you still have to listen to Yue'er's opinions."

"no problem."

Mo Sangyu said, "You can pack up and go back to Youdu City today."

Now that only Yan Qing and his group are in the city, and it has been too long, Mo Sangyu can't help but feel a little worried.

"…OK!"

Chu Canglan got up and angrily left the tent.

Yan Xu bowed to Feng Xingyu and Mo Sangyu, and then followed them out.

Just as he left, Chu Canglan walked back in, took out half a parchment from his pocket, and tossed it to Mo Sangyu: "Here's what you wanted."

Mo Sangyu picked it up and saw that it was the remaining half of the parchment.

Very good!

With this complete sheet, she could continue her research on the restriction.

For the next two days, Mo Sangyu did nothing but study this thing.

Feng Xingyu knew she cared a lot about this thing, so he didn't dare to disturb her.

On the third night, she summoned Feng Xingyu: "Tonight, you'll come with me somewhere."

Feng Xingyu was secretly pleased to see that she came to him first, instead of Ya Zi.

Without asking her where she was going, he dropped everything he was doing and followed her.

Under the cover of night, the two arrived at the highest hill on the grassland.

From here, you can almost overlook the entire grassland tribe.

The total area is roughly the size of five Youdu cities.

If the same restrictions as those in Youdu City were set up, it would probably exhaust her spiritual power.

However, now that I've finally figured it out, I have to give it a try.

The night wind howled, causing their clothes to flutter.

Mo Sangyu spread the parchment on his lap and said to Feng Xingyu, "I want to set up a protective barrier similar to that of Youdu City, covering the entire grassland. The process cannot be interrupted. You will protect me."

"…good."

Even though Feng Xingyu had many worries and doubts in his heart, he didn't say a word and simply agreed.

He walked a few steps behind her and stopped.

Mo Sangyu sat cross-legged, his hands forming a mudra, and spiritual energy flowed from his fingertips.

At first, it was just a faint point of light, but it gradually gathered into a stream, like invisible mercury, seeping into the land beneath her feet.

Soon, following some mysterious trajectory, it spread in all directions.

Feng Xingyu quietly stood behind her, able to clearly sense the drastic changes in the spiritual energy emanating from her.

It was an extremely subtle and immense power operation, which even he felt a slight sense of unease.

His worry deepened.

Time passed little by little.

Mo Sangyu's face grew paler and paler, and fine beads of sweat appeared on his forehead.

But her hands did not stop moving in the slightest, and her spiritual energy output remained stable and continuous.

Finally, as the last spiritual energy pattern closed, a faint, almost imperceptible glimmer of light flashed across the entire grassland before disappearing into the night.

The ban was in effect.

Mo Sangyu swayed and almost fell over.

Feng Xingyu kept his eyes fixed on her, and he immediately stepped forward and caught her.

She leaned against him, too exhausted to even speak.

"Yu'er?"

Feng Xingyu's heart tightened. He picked her up and carried her down the mountain quickly back to the tent.

He carefully placed her on the couch and covered her with a blanket.

Mo Sangyu had already fallen into a deep sleep, her breathing very shallow.

Feng Xingyu knew that Mo Sangyu had overexerted her spiritual energy and could recover with just a good night's sleep.

But he was still very worried that night and stayed by her side the whole time, without closing his eyes.

The next day, when Mo Sangyu woke up, it was already broad daylight.

As soon as she opened her eyes, she felt her spiritual power had been restored.

Feng Xingyu was sitting by the bed. Seeing that she had woken up, he quickly leaned down and asked anxiously, "How are you feeling? Is anything bothering you?"

"fine."

Mo Sangyu sat up: "I'm just a little hungry."

Feng Xingyu breathed a sigh of relief and got up to bring over the porridge and side dishes that had been kept warm.

Mo Sangyu had just finished eating when Gu Jinzhi arrived in a hurry.

"Master, Madam, something strange has happened!"

Mo Sangyu put down her bowl: "Is it that outside the normal entrances and exits on the outer edge of the grassland, are there other places where we can enter but not exit?"

Gu Jinzhi was taken aback: "I haven't said anything yet, how did Madam know?"

"I set it up."

Mo Sangyu wiped her mouth and looked at Feng Xingyu: "Let's go, let's go take a look together."

"what?"

Gu Jinzhi was stunned upon hearing this.

Seeing that they had already gone far away, he hurriedly followed them.

The group arrived at the edge of the tribe.

A large crowd had already gathered there, discussing the empty grassland in front of them.

"What's going on? This morning I wanted to go home through my usual route, but even though there was nothing in front of me, I just couldn't walk in. It was like I bumped into an invisible wall."

"Yes, this is so strange. Could it be that we've angered the spirit of the grasslands?"

"There's no need for anyone to panic."

Mo Sangyu stepped forward and reached out. At a height of three feet above the ground, he indeed encountered an invisible, flexible barrier.

She withdrew her hand, turned to the crowd and said, "This is nothing strange, nor has it offended any deity. It's just a protective barrier I set up last night."

The group looked at each other, their expressions puzzled.

"This wall can protect the grassland from foreign enemies."

Mo Sangyu explained, "Apart from a few designated entrances and exits, outsiders cannot trespass at will. This will make it safer for everyone to graze their livestock and live their lives, and they will no longer have to worry about being attacked by bandits, horse bandits, or other bad guys."

The crowd was quiet for a moment, then erupted into a buzz of discussion.

At first, there was surprise and doubt, but soon it turned into delight and admiration.

"Really? Then I can sleep soundly at night!"

"Madam is truly amazing! She possesses such abilities!"

"Great! I don't have to worry about my sheep being stolen anymore!"

Mo Sangyu listened to these discussions without much expression on his face. He simply said to Gu Jinzhi, "Go and summon a few chieftains. From now on, they will be responsible for the defense and security of the tribe."

"I'll go right away."

Gu Jinzhi turned around and gave an order. Within half an hour, several tribal leaders, as well as Yuan Zhao and Han Chong, arrived.

Han Chong had lived in Youdu City for several years and was no stranger to this kind of transparent defensive wall.

But how could Madam know how to make something like this?

I heard Lord Chu mention before that this was some kind of ancient, mysterious power, and yet the lady managed to create it so casually?

This method is terrifying.

Yuan Zhao was very excited.

He kept probing the invisible wall.

He discovered that the force with which he touched it would determine the force of the rebound.

In other words, if he moves gently, nothing will happen; but if he makes a direct impact, he will be thrown away by the force.

Great!

That's absolutely amazing!

"alright."

Mo Sangyu waited until they had probed enough before calling everyone over.

"Starting today, except for a few designated entrances and exits, no one may enter or exit from any other place, whether inside or outside."

She looked at the leaders and said, "You should immediately arrange for people to guard those entrances and exits. In addition, issue identity cards to all the people in the grassland tribes. After that, they can enter and exit freely with their identity cards. Outsiders will need to register before they can enter or exit."

After saying that, she looked at Han Chong and said, "You are more familiar with these procedures, so you can lead them to make arrangements."

Han Chong's expression turned serious, and he quickly replied, "Yes, Madam."

This was the first task his wife had personally assigned him, and he had to complete it well.

"I'm going to be busy again."

Feng Xingyu went over and took her hand: "Let's go back and rest for a while."

"Um."

Mo Sangyu knew he was worried about her health, so she gently squeezed his hand to reassure him.

The two returned to their tent.

At Feng Xingyu's insistence, she took another nap.

I made up for the sleep I missed from staying up all night researching the restrictions.

……

Two more days have passed.

"Sir, Madam, the preliminary survey is complete."

Gu Jinzhi spread a detailed map on the table.

"The route has been basically determined, and the geology, water sources, and possible obstacles along the way have all been clearly marked. The next step is to develop a specific construction plan and budget."

Mo Sangyu's gaze fell on the map, and he nodded: "Thank you for your hard work. Please come up with the plan and budget as soon as possible."

"Yes."

Gu Jinzhi put the map away: "In addition, things are progressing smoothly on Han Chong's side. The production of the identity tags and the arrangement of guards at the entrances and exits are being implemented."

"Um."

Feng Xingyu responded, "Please take care of things on the grasslands. My wife and I plan to return to Youdu City in the next few days."

Upon hearing this, a look of understanding flashed in Gu Jinzhi's eyes: "Are you and your wife preparing... to deal with the matter of the Iron River Kingdom?"

"That batch of weapons is almost finished being forged, and I need to go back to inspect them personally. As for the Iron River Kingdom, we have nearly two months to prepare, so there's no rush."

"Alright, I'll come up with a detailed attack plan after I've finished dealing with the road construction and the subsequent matters on the grassland."

Mo Sangyu, who was listening nearby, suddenly realized...

We really should find a helper for Gu Jinzhi.

What if we work him to death?

"Feng Xingyu, that helper is hard to find, why don't we find one for Mr. Gu first..."
