The Grand Chancellor held a high position of power and influence, and although he was not the emperor in name only, he was the emperor in reality.

But he was just a powerful official after all, and could never justify his actions.

Moreover, the Northern Dynasties had not only one great chancellor who commanded a large army, but also eight great pillars of the state.

The Eight Pillars of the State were also generals with military power.

If they were asked to kill the king, they would definitely not dare.

However, several generals would definitely be willing to kill the Grand Chancellor and replace him.

Yuwen Heng's biological father was one of the Eight Pillars of the State.

He is also a general whose strength is second only to that of the Grand Chancellor.

Yuwen Heng had exposed his ambition and strength too early, which caused discord between him and his father.

But, father and son are father and son after all, blood ties, how can they be easily severed?

All I want is my son's submission and loyalty.

As a son, all you need to do is kneel down, admit your mistakes to your father, and work hard to perform well and make achievements.

The father and son can be reconciled.

Not to mention, the father and son have a common enemy - Otsukizai!

"So, Yuwen Heng found the Grand Chancellor's 'weakness' and secretly returned to Pingcheng to join forces with his biological father?"

Gu Qingcheng knew Yuwen Heng too well and was too smart, so she guessed the truth after just a little thought.

At most, she still didn't know what Otsukasa's "weakness" was.

But, this is not important.

The important thing is——

"It seems that the Northern Dynasty is going to be in chaos!"

There will definitely not be peaceful means to kill the Grand Chancellor.

As long as action is taken, it will cause a shock in the court and even the entire capital.

When Chen Duan killed Chen Jing and triggered the Tangquan Palace Incident, Yuwen Heng tried to "take advantage of the situation".

Now, it was the Northern Dynasty's turn to stage a coup, and Gu Qingcheng felt that she should "retaliate"...
