Tao Hongtu returned to the Ministry of Revenue, feeling as anxious as an ant on a hot oil pan.

He summoned Zheng Yongning.

"Go and put up a sign at the entrance."

The banquet was in the evening, and Nanzhi took advantage of her free time in the afternoon to visit the Ministry of Revenue.

Standing in front of the household registration office, Nanzhi stared at the sign on the door.

"No dogs or officials allowed inside?!"

She looked to her side: "Lord Zheng, what's going on?"

Zheng Yongning looked up and gestured with his eyes.

"It was done by the Minister!"

"Your Excellency may not know this, but the Ministry of Works often poachs talent from the Ministry of Revenue. Our Minister has no choice but to do so."

Nanzhi understood.

Talent protection is needed, as people are afraid of job-hopping.

This is an interesting idea, though. I'll try to put one in her bedroom sometime.

It reads: "Song Hanyan and dogs are not allowed inside."

To prevent the Ministry of Works from discovering Nanzhi's talent, the Minister of Revenue issued a stern warning to his subordinates.

This method must not be leaked, and you must not mention Lord Nan in front of outsiders.

Those who disobey will be sent to the Ministry of War to work as blacksmiths.

But he forgot that the person in charge hadn't given him a warning yet.

The Ministry of Revenue was on high alert, not even a fly could get past it.

Ministry of Works.

The people sent to gather information couldn't even get through the door.

Gong Qijun, the Minister of Works, found it increasingly strange.

Old Tao's grandson, could he be hiding some great treasure?

No, I need to investigate this thoroughly tonight.

A person rushed in.

He was very indignant: "Sir, there is a sign in front of the Ministry of Revenue that says, 'Ministry of Works and dogs are not allowed to enter.'"

"What!" Gong Qijun exclaimed in surprise.

To be so highly regarded by Tao Hongtu, one must be no ordinary person.

"There's something fishy going on, there's definitely something fishy going on."

Gong Qijun slammed his fist on the table, "If I can't find out who that person is tonight, I'm not Gong!"

"Go, let's put up a sign that says, 'Ministry of Revenue and dogs (Tao Hongtu) are not allowed inside!'"

The officials below looked embarrassed.

"Sir, is this appropriate?"

Gong Qijun: "Why is it inappropriate? Apart from him, everyone in the Ministry of Revenue is a person."
