After hearing James's words, Lex exclaimed in surprise, his body trembling.

"What?" he stammered. This was something he had never dared to imagine. "Is this real, James?"

The people gathered at the door, unaware of what had transpired, glanced at Lex, puzzled by his reaction. "Grandpa, let's talk over there," James said, pulling Lex away. He reassured him, "Grandpa, I swear what I've said is true. I've already made arrangements. You can hold your birthday party at the House of Royals, if you'd like. Holding your eightieth birthday there will be the first step in the Callahans becoming an influential family, once the news spreads throughout Cansington."

After a moment of excitement, Lex calmed down. He glanced at James.

"Do you know what kind of place the House of Royals is, James? It's been under construction for years, and countless wealthy families have tried to purchase it. Some even offered billions of dollars, but there was no way to buy it. Now you're telling me I can hold my birthday celebration there?"

"Yes," James replied, his expression sincere.

"Who do you think you are?" Lex asked.

"Grandpa, I'll be honest with you. I was a general in the Southern Plains. However, I made a mistake and was court-martialed. The House of Royals is owned by the Commander of the Southern Plains, the Black Dragon. The place was awarded to him, and since the Black Dragon is far away in the Southern Plains" James repeated the story he'd told Thea. "Although I was expelled from the military and can never return, the commander has been looking out for me. I've already called him and received his permission."

"Y-you're a general?" Lex's expression changed subtly. He never imagined the Callahans' live-in son-in-law was a general. He coughed. "I I violated military law and was court-martialed, expelled from the army. However I can assure you, Grandpa, that everything I said is genuine. You really can hold your birthday party at the House of Royals."

Initially, James had planned to hold his wedding with Thea at the House of Royals. However, a misunderstanding arose between them. To prevent a divorce, he had to approach the proud Lex.

"You're a good grandson-in-law," Lex said, his frown relaxing as he patted James on the shoulder. "It doesn't matter that you were expelled from the army; you're a Callahan now. We'll take care of you."

"Thank you, Grandpa. However, Thea has been clamoring for a divorce for the past two days. I've exhausted all means to beg the commander for this opportunity. He finally agreed, seeing that I saved him eight years ago. Grandpa, could you convince Thea not to divorce me?"

"That won't be a problem," Lex smiled broadly.

The House of Royals—the most prosperous and mysterious villa in Cansington. The entire city would be shocked to hear he was holding his birthday party there. "Thank you, Grandpa," James smiled. The rest would be easy after convincing Lex. The misunderstanding could be explained slowly, as long as they didn't get divorced.

"However, Grandpa, you can't tell others how you secured this opportunity. I have a record and will get in trouble if I attract the attention of the authorities. The opportunity to hold your birthday celebration there will be wasted," James cautioned, knowing Lex's egotistical nature.
