The Cao family can only ask Huang Donghai to make a move once, so naturally they cannot use this favor lightly.

Moreover, the Venerable Black Witch has always been cautious, working in secret, and never really showing his face.

Even Huang Donghai found it difficult to catch the opponent.

When a cat catches a mouse, the mouse has to come out of the hole.

"Dad, the Venerable Black Witch is about to kill him, so why not use it?" Concubine Cao Xuan asked tentatively.

My father, can you bear it too much?

"Don't worry, I have my own arrangements."

Cao Guan said indifferently: "It's really about to be a crisis moment, just a signal, and Huang Donghai will be there soon."

"Okay, you are the head of the family, you decide." Concubine Cao Xuan did not say much.

Huang Donghai's hole card really cannot be used easily.

The best result is that the Cao family relies on its own strength to resolve this crisis and destroy the Black Witch.

Not only does this leave a trump card, but it also inspires people.

"Uncle Cao, I'm a little curious. What kind of enmity is there between the Venerable Black Witch and the Cao family?"

At this moment, Lu Chen asked suddenly.

"this......"

Cao Guan was about to speak but stopped.

"Uncle Cao, I'm just asking casually, you don't have to take it to heart." Lu Chen smiled.

If it involves family secrets, it's really hard to speak up.

"Dad, just say what you want, Lu Chen is not an outsider." Concubine Cao Xuan persuaded.

She only had a partial understanding of the grievances between the two parties.

"Okay, since you want to know, I'll just tell you."

Cao Guan hesitated for two seconds, and finally chose to speak: "Speaking of the grudges between the Cao family and the Black Witch, it is actually not complicated. It is mainly because of wealth.

Tracing back to the source, the ancestors of the Cao family used to be the royal family. During the glorious period, they accumulated a lot of treasures, which can be said to be incomparably rich!

Later, when the dynasty changed, the ancestor of the Cao family buried the treasure in a safe place and drew a treasure map.

In the past, the treasure map was eventually divided into three parts and collected separately by the three sons of the ancestor of the Cao family.

Originally, the ancestor of the Cao family was planning to use the treasure to make a comeback.

Unexpectedly, the three sons turned against each other in the end, and each took a part of the treasure map and disappeared.

Since then, the Cao family has been divided into three lines, each developing independently.

After hundreds of years of tempering, the three lines of the Cao family have been strong and weak, rising and falling.

The treasure map has been passed down from generation to generation. JrNovels.com
