Among the seven Jedi sword techniques, Surishu emphasizes defense but lacks offensive capabilities. Makassi emphasizes offense but lacks defensive capabilities. Therefore, the fifth sword technique, Xi'an and Qiangshuo, is a "balanced" sword technique that offers both offensive and defensive capabilities. It's suitable for both single-handed and dual-wielding swordsmanship.

Darth Vader is a powerful example of this swordsmanship, as evidenced by his ability to swing his sword with only one hand. In other words, Darth Vader in the movies is actually always holding back, and his peak combat power is probably his dual-wielding style. In the movie "Revenge of the Sith," Count Dooku, the ultimate warrior of the Confederacy of Independent Systems, dies at the hands of Anakin's dual-wielding style.

At this moment, the two engaged in a fierce battle. Their lightsabers clashed in the air, dazzling sparks erupting from their blades. Their swordplay was exquisite, their movements emitting powerful Force fluctuations.

Soon, the battle reached its climax, and the two lightsabers danced dazzlingly. Their speed and strength reached their limits, and every clash could cause the air to distort and the Force to vibrate.

Though old, Obi-Wan's wisdom and experience allowed him to hold his own against Darth Vader, but Darth Vader's strength and determination always gave him the upper hand.

In the end, Obi-Wan was defeated by Darth Vader. He fell to the ground, and the lightsaber slipped from his hand and fell to the ground not far away with a heavy thud.

Darth Vader stood in victory, looking down at his opponent. His eyes revealed pain and confusion. He recalled the past with Obi-Wan, the loyalty and friendship they once had now become very distant.

He slowly took off his helmet, revealing the ferocious face inside, and spoke to Obi-Wan.

"Obi-Wan, you've never thought that one day you'd be defeated by me, have you?"

"You are...Anakin?" Obi-Wan's eyes suddenly widened, his face filled with disbelief. He had originally thought that Anakin was dead, having been killed by him on Mustafar ten years ago.

"You seem surprised I'm still alive? That's right! I was almost dead, but in the end, I endured the burning of the magma and climbed out of hell step by step, all for revenge! And my current appearance is all thanks to you!"

Obi-Wan looked at Anakin with a complex expression, filled with guilt for his apprentice. He tried to persuade him with words and reason, hoping that he would return to the light side. But Darth Vader was already deeply trapped in darkness and would not listen to any advice.

"Anakin, you were once my beloved disciple, and we have had countless experiences and memories. Please turn back and don't continue to follow the power of the dark side! That will only make you continue to slide into the endless abyss!" Obi-Wan's voice was full of sadness and expectation.

However, Darth Vader sneered, his eyes revealing great pain and anger.

"Obi-Wan, your time is over. The Jedi Order has been destroyed for ten years. Now, only the powerful dark side can bring me true power and freedom!" Darth Vader's voice was full of determination and confidence.

Obi-Wan stood up with difficulty. He looked at Darth Vader with disappointment and sadness in his eyes.

"Anakin, you were once my pride, but now you have become twisted and corrupted. But I will not give up on you. I will keep trying and looking for opportunities to bring you back to the light side!"

"Enough! Anakin is dead! Now, my name is Darth Vader! And you don't stand a chance. It's over..."

Darth Vader slowly raised the lightsaber in his hand, ready to make the final judgment on Obi-Wan.

Just as the red lightsaber was about to cut Obi-Wan's neck, a blue lightsaber blocked it.

"Owen? How is this possible?"

Without any nonsense, while the Sir was still in a daze, Jed Lee, who possessed Owen, directly picked up Obi-Wan and retreated quickly.

Darth Vader wanted to use the Force to grab them and suck them back in. But Jed Lee was prepared and directly used the "5 Seconds of Real Man" that he had just won from the system lottery to knock the Force back.

With a loud bang, both sides were shaken apart at the same time, leaving a considerable distance between them.

After Darth Vader stabilized his body, he wanted to continue forward, but a large number of Astra Militarum soldiers appeared in the corridor behind him and fired at him crazily.

"Damn rubbish! You're looking for death!"

Just as Darth Vader was distracted by defense, a spaceship quickly flew into the hangar under the cover of the Quantum 00 Gundam.

The pilot, who was clearly a skilled pilot, opened the hatch before the plane even touched down. At the same time, a cry reached everyone's ears.

"No time to waste! Get on the spaceship!"

Darth Vader saw that everyone was trying to run away and roared, wanting to use the same trick again to pull them down.

But at the same time, Zhong Kai, who was driving the Quantum 00 Gundam, activated the quantum burst mode and directly pushed Darth Vader back with all his strength with a beam saber.

Faced with such a powerful laser, Darth Vader had no choice but to defend himself with all his might. His constant roars and howls proved his rage at the moment.

However, as the ship lifted off, Obi-Wan once again took the "high ground." Using the Force, he hurled a large amount of metal and debris from the hangar at Darth Vader like a meteorite, burying and enveloping him completely.

After finishing all this, they didn't dare to stay any longer. The "Moon-class Cruiser" was already destroyed, and the space battle outside was still going on to provide cover, so they had to retreat quickly!

Not long after they flew out of the hangar, Darth Vader, who was buried in the rubble, suddenly jumped out with a bang.

He silently looked at the direction Obi-Wan left, his heart full of contradictions and entanglements. He knew that Obi-Wan's words left a glimmer of hope in his heart, but the power of the dark side was still raging deep in his heart.

This battle of grudges between master and apprentice is far from over, their destinies will continue to intertwine, and their duels and contests will begin again.

Looking back at the group of Astra Militarum soldiers who were still charging forward one after another, Darth Vader's eyes flashed with coldness and chill.

In this battle, no one is a true winner. There is only pain and hatred!

The "Moon-class cruiser"—fallen! Its body, transformed into a blaze among the stars. Aside from a small number of crew members who retreated, the entire fleet of Astra Militarum soldiers, some Battle Sisters, and a small number of Mechanicus were killed!
