Seeing that Gongsun Yunyan still wanted to say something more, Mo Han cut in, “Besides, I’m used to being lazy. If you expect me to tutor you every day, I might as well just die, hehe.”

Gongsun Yunyan said no more upon hearing Mo Han’s words. She performed a junior’s bow toward him and said, “Then Yunyan thanks Big Brother for agreeing to accept me as your little sister.”

Mo Han smiled and replied, “In that case, if your Big Brother runs out of money in the future, I can come to you for a loan, right?”

Hearing Mo Han’s words, everyone felt an urge to hit him. To have hundreds of thousands of gold coins from gambling and still claim to be broke? It even earned a few eye-rolls from the beautiful women nearby.

Mo Han could only say awkwardly, “Uh, forget I said anything. I thought the atmosphere was a bit dull, just trying to cheer everyone up. Don’t misunderstand, you all. I should be heading off now.”

After bidding farewell to Shui Ling’er, Raal, and Gongsun Yunyan, he left with Daili and the others to return to the city.

On the way back, Daili, smiling beside him, said, “You just love talking nonsense. So, you’ve picked up another beautiful little sister—feeling quite pleased with yourself, are you?”

Mo Han immediately waved his hands in protest. “I’m wronged, my dear wife! You heard her; it was Gongsun Yunyan who insisted on recognizing me as her Big Brother. I accepted it with complete purity! Don't get the wrong idea, I am a true gentleman!”

Hearing Mo Han call her 'wife,' Daili’s face flushed crimson. She shyly lowered her head, feeling as if she had drunk sweet honey, yet her mouth stubbornly protested, “Who’s your wife? There are so many people here; don’t shout nonsense. And you dare call yourself a true gentleman? Then there are no good people left in this world.”

Mo Han certainly knew Daili’s words were contrary to her feelings. He slapped his forehead, feigning sudden realization, “Oh, I get it now. You mean when we’re alone, it’s fine to call you my wife. Why didn’t you say so earlier? I’ll definitely remember next time.”

This made Daili’s face even redder. She reached out and pinched Mo Han a few times, eliciting a look of agony on his face. Everyone watching burst into happy laughter.

Mo Han pretended to be indignant, crying out, “You people have no humanity! You build your happiness upon my suffering! How pitiful I am!”

As soon as he finished speaking, even Daili started laughing. Anna looked at Mo Han and Daili with envy, whatever she was thinking, only she knew.

Not long after Mo Han returned to the inn to rest, Gongsun Yunyan and Shui Ling’er requested an audience. Mo Han smiled at Gongsun Yunyan and said, “Surely you haven’t come so quickly to hand over money to me, have you?”

Gongsun Yunyan replied, blushing, “Big Brother, you know it won't be that fast; please don’t tease me. I came today because there is something I need to consult Big Brother about.”

Mo Han put on a long face and declared, “I knew being a Big Brother wouldn’t be easy. You’re not going to ask me for a loan, are you? I’m dirt poor.” This comment made both beauties laugh again.

In truth, Mo Han already knew the purpose of Gongsun Yunyan’s visit, but given his nature, it felt wrong not to tease a beautiful woman a little.

Gongsun Yunyan began, “I believe Big Brother already knows why Yunyan is here?” Mo Han answered, “Are you here to say that since the defense of Feiji City has such a huge flaw, you want me to fix it?” Gongsun Yunyan quickly flattered him, “I knew Big Brother would understand my intentions! With your wisdom, how could you not know? Ling’er even said you were as dumb as a pig and couldn't possibly know anything.”

As soon as she finished, Shui Ling’er, her face red, interjected, “You wretched Yunyan! Who told you to say such things?” She then huffed at Mo Han and turned away, refusing to speak further.

Mo Han acted wounded, “What kind of world is this? The person you called a pig didn't even get angry, yet you are upset? Ah, I am just too honest.” This made both women laugh. Shui Ling’er laughed and chided, “If you’re honest, then there are no good people in the world.”

Hearing this, Mo Han scratched his head awkwardly. “Ugh, why can’t girls be a little more tactful when they speak? I call that being clever, understand? Forget it, I won’t argue with you.”

Shui Ling’er offered no rebuttal, only smiling, “Yes, very cunning.” This left Mo Han speechless for a moment.

At this point, Gongsun Yunyan spoke with earnestness, “Big Brother, since you know the major weakness in Feiji City’s defense, is there a way to remedy it?” Mo Han laughed, “Naturally, there is. Have you forgotten who I am?” Gongsun Yunyan was overjoyed. “Please, Big Brother, teach me how to fix it! I thank you on behalf of the people and soldiers of Feiji City. I will certainly report this to the Emperor and ask him to reward you.”

Mo Han chuckled, “No need for thanks, but don’t make the reward too extravagant, hehe. It’d be better to get something tangible, like a few hundred thousand gold coins, or a few thousand acres of land. I’m not a man of high demands; I’m easily satisfied.” This drew straight eye-rolls from Shui Ling’er and Gongsun Yunyan.

Mo Han continued, “Actually, the defense is quite simple. The key lies with that small island.” Hearing this, Gongsun Yunyan and Shui Ling’er pondered deeply, unable to figure out how the island crucial for breaking the siege could also be crucial for defense.

Mo Han went on, “It’s similar to what I said earlier. If you want to firmly hold Feiji City, you just need to station a unit of Rocket Troopers, Infantry, and Catapults there.” Gongsun Yunyan and Shui Ling’er seemed to grasp something after hearing his words.

Mo Han dipped his finger in some tea and drew on the table. “For example, Feiji City is in the center, the small island is to the left, and the forest borders the island. If the enemy attacks via water, the result will be as I stated before—impossible. That leaves them only one option: bypassing through the forest to attack from the front. But if they go around to the front of the forest, they enter the siege range of our city’s catapults. Moreover, attacking the island from the forest side is extremely difficult. Therefore, a frontal assault is unlikely. The only option left is for the enemy to push through the forest. The closest point to the island is at this end of the forest; our crossbowmen’s heavy quarrels can barely reach the island. If you preemptively douse the forest with oil and ignite it once the enemy’s main force is inside, their offensive will naturally collapse. Furthermore, if catapults are mounted on the island, due to the terrain, their maximum range of four thousand meters can perfectly strike the enemy advancing along the narrow road on the right side of the forest, while the enemy can only defend. Think about it—a battle where one side only defends and never attacks—what do you think the outcome will be?”

After listening to Mo Han’s explanation, Gongsun Yunyan’s eyes shone brightly. She exclaimed excitedly, “I understand, Big Brother, you are truly amazing! You’ve enlightened me in just a few words! I must go arrange this right now. Ling’er, I’m truly sorry; you’ll have to return to the cathedral by yourself later.” With that, she rushed out like a gust of wind.

Mo Han watched her go and laughed, “What a fiery girl; she is truly swift as the wind and decisive as rain.” He then noticed Shui Ling’er simply staring at him without speaking, prompting an awkward laugh. “Hehe, does Her Holiness the Saintess also wish to depart?”
