Duan Li'er gave Luo Changqing a look, handed the black ball to Luo Changqing, and let Luo Changqing go first, because the techniques he used required the assistance of mental power, and he was afraid that the spiritual power would touch the ball.

Luo Changqing took the black ball and quickly ran towards the entrance of the tunnel, and at the same time, the barbarian also opened his huge mouth and roared!

Luo Changqing had also entered the tunnel, and the knife held in Duan Li'er's right hand also overflowed with a hint of red hazy brilliance!

His sharp eyes stared closely at the barbarian who was more than ten feet tall, watched the barbarian roar, and took a deep breath!

The long sword he was holding tightly had already overflowed with a trace of turbid soul qi at this time, and his right hand was also trembling slightly, although he cooperated with the Silent Spirit Sword Technique not to overflow the attribute fluctuation pressure, but now it overflowed some because the fluctuation was too violent.

Slowly, the red glow on the long sword had disappeared, and it was replaced by a trace of terrifying evil aura, which exuded a terrifying aura! Even the barbarian was shocked by this and stopped roaring!

"Extremely resolute strike!" Duan Li'er let out a low snort, and his body shot towards the barbarian like light, and the knife that exuded a terrifying aura slashed towards the barbarian like lightning!

Two black lights flashed! The barbarian's chest had been split twice by Duan Li'er, and it was engraved on the barbarian's chest like a cross!

With a bang, the barbarian's huge body fell heavily to the ground, blood gushed out of the cut chest frantically, and Duan Li'er also quickly ran towards the entrance of the tunnel at this time!

Two hits can kill a barbarian! This is the power of the "Nine Strikes of Extreme Perseverance"!

At this moment, the roar of the dead barbarian had reached all parts of the barbarian lair, and the barbarians knew that an enemy had infiltrated.

The barbarian patriarch roared wildly, and then rushed over, and on the way many boulder houses collapsed, he was extremely fast, and in a blink of an eye he came to the grass hut, looking at the dead clansmen, he roared again, he also found the tunnel, and roared wildly towards the entrance of the tunnel.

This made Duan Li'er and Luo Changqing inside be shaken by the huge whistling sound!

Duan Li'er entered the tunnel, and quickly caught up with Luo Changqing, and they were running through the tunnel!

They were very uncomfortable with the angry roar all the way, but fortunately, both of them had good concentration and could bear it, if it were someone else, they might have collapsed long ago!

"Hehe, it's time to go out!" Duan Li'er said with a smile.

"You killed that barbarian just now?" Luo Changqing asked.

"Well, what's wrong?"

"Not much!" Luo Changqing had already entered the tunnel, although Duan Li'er came in later, but the interval was not long, which meant that Duan Li'er could kill that barbarian in a short time!

This also made Luo Changqing very surprised, originally he thought that he had advanced to the Golden Immortal Stage, and he would definitely be on par with Duan Li'er, but now he felt that he was still inferior to Duan Li'er, because Duan Li'er was only in the foundation building period now, and he also knew that Duan Li'er would soon be able to break through to the Dan Formation Period, and when the time came, his strength would definitely rise again!

"Changqing, if you fuse that piece of Thunder Spirit Snow Lotus, maybe your strength will increase a lot!" Duan Li'er saw through Luo Changqing's thoughts!

"Maybe!" Luo Changqing sighed lightly.

……

"Haha, finally got the black ball!" they had returned to the hall in the Sky Tree.

"The two young heroes are really not simple!" Mu Zhenwen sighed.

"If it weren't for the help of Patriarch Mu, we wouldn't be so smooth!" Duan Li'er said modestly, if it weren't for Mu Zhenwen to improve their strength, their speed would not be so fast, if the speed was slower, they wouldn't dare to break into the barbarian nest like this.
