I only reached the Foundation Establishment stage at eighty years old, and then the system appeared.

Along the way, they proceeded cautiously, avoiding the eyes and ears of the Prince of Zhenbei, and finally arrived at the outside of that secluded manor.

The manor was heavily guarded, but Yang Hongbo and his group were all skilled martial artists, so they naturally had a way to sneak in.

Under the cover of night, they stealthily infiltrated the manor, evading wave after wave of guards, and finally arrived at the core area of ​​the manor.

In a secret room, they overheard a conversation between the Prince of Zhenbei and a young man.

"Sixth Prince, are you really determined to do this?" The Prince of Zhenbei's voice carried a hint of hesitation.

"Prince Zhenbei, what are you hesitating for?" The young man's voice was cold and firm. "The position of Crown Prince should belong to someone with talent. I am the most suitable candidate."

"However, the Crown Prince has many supporters, so it won't be easy for us to take him down," the Prince of Zhenbei said worriedly.

"Hmph, supporters?" The Sixth Prince sneered. "As long as our plan is meticulous, what do those supporters matter? I'll shut them all up one by one."

After a moment of silence, the Prince of Zhenbei finally made up his mind: "Alright, since the Sixth Prince is so confident, I'll take the gamble with you. However, we need to deal with that troublesome Yang Hongbo first."

"Yang Hongbo?" The Sixth Prince frowned. "Isn't he your son? I heard he's only five or six years old, just a nobody. Why bother with him?"

"Sixth Prince, you may not know this," the Prince of Zhenbei explained, "Although Yang Hongbo comes from a humble background, he is quite capable. He has gathered a group of martial artists and has harassed my Prince's residence many times. I suspect that he has a larger force supporting him."

"Oh?" A hint of curiosity flashed in the Sixth Prince's eyes. "Is that so? Then we should investigate this Yang Hongbo thoroughly. However, our primary task right now is to deal with the Crown Prince. We can put Yang Hongbo's matter aside for now."

Hearing this from outside the secret chamber, Yang Hongbo sneered inwardly. He had originally thought the Prince of Zhenbei was a remarkable figure, but he never expected him to collude with the Sixth Prince in an attempt to usurp the throne.

However, that was not his main concern. He had come here solely to uncover the secrets of the Prince of Zhenbei and throw the Prince's residence into chaos.

Therefore, Yang Hongbo signaled Ying Sha and the others not to act rashly. They quietly withdrew from the manor and returned to the mountain stronghold.

Upon returning to the mountain stronghold, Yang Hongbo did not tell anyone about the collusion between the Prince of Zhenbei and the Sixth Prince. He simply intensified his harassment of the Prince of Zhenbei's residence and began plotting how to deal with the Prince of Zhenbei's wives and children.

Over the next few months, Yang Hongbo used his points to acquire more martial artists and hidden weapons. He sent Shadow Fiend and others to infiltrate the Prince's mansion and kill all the servants who had bullied him. Then, he turned his attention to the Prince of Zhenbei's wives and children.

He didn't kill them directly, but instead used various methods to plunge them into panic and despair. Some wives were so frightened they went insane, and some children were kidnapped and their whereabouts remain unknown.

Upon learning this news, the Prince of Zhenbei flew into a rage. He ordered a city-wide search for Yang Hongbo and his accomplices, but they could not be found.

In truth, the Prince of Zhenbei knew that Yang Hongbo was behind all of this. However, for the sake of his reputation, he was too embarrassed to openly confront Yang Hongbo.

After all, the two were father and son. If the world knew that they had become enemies, he would lose all face.

The Prince of Zhenbei simply couldn't understand how Yang Hongbo had managed to take away the gold and silver treasures from the Prince's mansion, since these things weighed over 100,000 jin in total, and no one in the mansion had noticed them the night they went missing.

That day, the Prince of Zhenbei sat alone in his study, his brow furrowed. His personal guard cautiously entered and whispered, "Your Highness, Yang Hongbo is becoming increasingly arrogant. Rumors are circulating that the decline of the Prince's residence is related to him. If this continues, I'm afraid..."

The Prince of Zhenbei slammed his fist on the table and roared, "How could I not know! But that rebellious son acts in secret, and the men I sent out couldn't find a trace of him, let alone capture him."

The guard hesitated for a moment, then said, "Your Highness, why don't we post notices and offer a reward for Yang Hongbo's capture? That way, we might be able to find him with the help of people in the martial arts world."

The Prince of Zhenbei sneered, "A bounty? Wouldn't that be announcing to the world that I am irreconcilably opposed to my own son? Where would that leave my face?"

The guard lowered his head, not daring to say another word.

Just then, the study door was suddenly pushed open, and a figure strode in. The Prince of Zhenbei looked closely and saw that it was the Sixth Prince.

"Sixth Prince, what brings you here?" The Prince of Zhenbei quickly stood up to greet him.

The Sixth Prince's face was grim as he said, "Prince Zhenbei, I've come today to ask you about the progress in dealing with Yang Hongbo."

The Prince of Zhenbei sighed helplessly: "Sixth Prince, that rebellious son is extremely cunning. I have sent men to capture him many times, but all have failed."

The Sixth Prince frowned: "Prince Zhenbei, are you perhaps too soft-hearted to harm your own son?"

The Prince of Zhenbei quickly waved his hand: "Sixth Prince, what are you saying? That rebellious son treated me and the Prince's mansion so badly that I wish I could tear him to pieces. But his whereabouts are unpredictable, and he is truly difficult to catch."

The Sixth Prince sneered, "Prince Zhenbei, you are a regional overlord, yet you can't even handle your own son. How can you expect to achieve great things with me?"

The Prince of Zhenbei was furious, but remembering that he still needed the Sixth Prince's help, he had no choice but to suppress his anger and said, "Sixth Prince, rest assured, I will find a way to deal with Yang Hongbo as soon as possible."

The Sixth Prince glanced at the Prince of Zhenbei and said, "I hope the Prince of Zhenbei will not disappoint me. The assassination plot against the Crown Prince has repeatedly failed, and I suspect it is related to Yang Hongbo."

The Prince of Zhenbei was startled: "Sixth Prince, do you mean Yang Hongbo is sabotaging our plans?"

The Sixth Prince nodded: "That's right. Every assassination attempt is thwarted by a mysterious person at the crucial moment. I suspect that this mysterious person is Yang Hongbo."

After a moment of contemplation, the Prince of Zhenbei said, "Sixth Prince, if it was truly that rebellious son's doing, I will make him pay the price. However, our most urgent task now is to find a countermeasure; we cannot allow the assassination plan to fail again."

The Sixth Prince nodded slightly: "What the Prince of Zhenbei said is absolutely right. I have already rearranged the assassination plan, and this time we must ensure that it goes perfectly. At the same time, you must also deal with Yang Hongbo as soon as possible."

The Prince of Zhenbei quickly replied, "Sixth Prince, rest assured, I will make the arrangements immediately."

After the Sixth Prince left, the Prince of Zhenbei sat in his chair, lost in thought. He knew he had to resolve Yang Hongbo's problem as soon as possible, otherwise he would not only lose the Sixth Prince's trust, but also plunge his palace into an even more dangerous situation.

Meanwhile, Yang Hongbo was in the mountain stronghold discussing the next course of action with Ying Sha and others.

"Shadow Sha, have the Prince of Zhenbei and the Sixth Prince made any moves lately?" Yang Hongbo asked.

Ying Sha replied, "Young Master, according to our scouts, the Sixth Prince seems to be plotting a new assassination of the Crown Prince, while the Prince of Zhenbei is searching for our whereabouts."

Yang Hongbo sneered, "Hmph, they still want to assassinate the Crown Prince? They're delusional. Ying Sha, continue to send people to monitor their every move. Report to me immediately if you discover any action they take."

"Yes, young master," Shadow Fiend replied.

At this moment, another subordinate walked in and said, "Young master, there is a man outside who claims to be an envoy from the Prince of Zhenbei's mansion requesting an audience."

Yang Hongbo frowned: "An envoy from the Prince of Zhenbei's mansion? What's he doing here?"

The subordinate shook his head: "I don't know. He said he has something important to discuss with the young master in person."

Yang Hongbo pondered for a moment and said, "Bring him in."

A short while later, the envoy was brought before Yang Hongbo. Upon seeing Yang Hongbo, the envoy immediately bowed and said, "Young Master Yang, I have been sent by the Prince of Zhenbei to negotiate with you."

Yang Hongbo sneered, "Negotiation? The Prince of Zhenbei still has the nerve to negotiate with me? Has he forgotten how he treated me and my mother?"

The envoy's expression changed, and he quickly said, "Young Master Yang, those are all things of the past. The Prince of Zhenbei is now filled with regret, and he hopes that you can let go of your hatred and reconcile with him."

Yang Hongbo laughed loudly: "Reconcile? Does he think he can erase the past with a simple regret? Envoy, go back and tell the Prince of Zhenbei that I will not let him go unless he pays the price he deserves."

Seeing Yang Hongbo's resolute attitude, the envoy knew he couldn't persuade him, so he said, "Young Master Yang, the Prince of Zhenbei said that as long as you are willing to give up, he can give you generous compensation, including gold, silver, jewelry, land, and real estate."

Yang Hongbo shook his head: "Gold, silver, jewelry, land, and real estate? I don't care about those. What I want is the complete collapse of the Zhenbei Prince's mansion and the disgrace of the Zhenbei Prince."

The envoy sighed helplessly, "Young Master Yang, why are you so persistent? Between father and son, what enmity cannot be resolved?"

Yang Hongbo's eyes turned cold: "Envoy, you don't need to pretend to advise me here. Go back and tell the Prince of Zhenbei that his good days are numbered."

Seeing that his persuasion was ineffective, the messenger had no choice but to leave the mountain stronghold in disgrace.

Watching the envoy's departing figure, Yang Hongbo's eyes gleamed with unwavering determination. He knew his path to revenge was long, but he had already taken a firm first step. He believed that one day, he would make the Prince of Zhenbei pay the price he deserved.

In the days that followed, Yang Hongbo continued to sabotage everything the Prince of Zhenbei and the Sixth Prince did. The Sixth Prince's assassination plot against the Crown Prince failed time and time again, infuriating him. Meanwhile, the Prince of Zhenbei was plunged into endless trouble due to Yang Hongbo's constant harassment.

Finally, one day, the Prince of Zhenbei could no longer bear the pressure. He decided to personally lead his troops to the mountain stronghold to fight Yang Hongbo to the death.

When the army of the Prince of Zhenbei arrived at the mountain stronghold, Yang Hongbo had already led his men to prepare for battle.

The Prince of Zhenbei looked at Yang Hongbo, his eyes filled with complex emotions: "You unfilial son, if you are willing to stop today, I may spare your life."

Yang Hongbo sneered: "Prince Zhenbei, do you think I'd believe your nonsense? Today, it's either you or me who dies."

After saying this, the two sides engaged in a fierce battle. Yang Hongbo took the lead, leading his men in a valiant fight. Although the Prince of Zhenbei had a superior number of troops, they gradually found themselves in a difficult situation under the tenacious resistance of Yang Hongbo and his men.

At a crucial moment in the battle, the Sixth Prince suddenly arrived with a troop of men. It turned out that the Sixth Prince had learned that the Prince of Zhenbei had personally led troops to attack the mountain stronghold, and fearing that things might change, he had come to provide support.

The arrival of the Sixth Prince further heightened tensions. Yang Hongbo looked at the Sixth Prince and knew in his heart that today's battle would determine his fate.

He took a deep breath and shouted, "Brothers, for our dignity and justice, charge!"

With a shout of encouragement, the crowd charged towards the enemy. A thrilling battle unfolded before the mountain stronghold…
