"Okay, my old Xiao Tou is waiting for you inside" Old Xiao Tou also knew at this time that the purpose of the Nangong family's construction of the nirvana special training room was to train the killer's personal strength, how could it leave loopholes and make it easy for people to succeed in the confusion.

Old Xiao bent down and walked into the passage, which was almost the same as the outside, and he could see everything in the stone room through the window.

As soon as he walked out of the stone room, there was a sound of gears snapping behind him, the door had been closed, and on the contrary, in front of the Yan brothers and the others, the entrance reappeared.

Everything in the stone chamber has also returned to normal, as if no one has broken through at all.

With such a sophisticated design, Lao Xiao Tou had to be a little surprised by the Nangong family's good intentions at this time.

"I'm coming" The sword slave stepped into the stone room, his body suddenly changed, and a great sword swept across the entire stone room with an incomparably sharp sword aura.

Sou!

A sword!

Seventeen live targets fell to the ground, and the incomparably calm figure of the sword slave fell to the ground, as if the sword shadow in the sky just now was not launched by him.

"It's the sword bone, which makes his whole person, and even his momentum change dramatically" Lao Xiaotou stared at the sword slave's eyes getting brighter and brighter, he didn't expect the sword slave's strength to improve to such a point, and he was like two people when he fought with him before.

Sou! The sword slave's figure easily fell to Lao Xiaotou's side, and he smiled slightly: "Master, I feel that my strength is about to break through the ground field."

"The earth field, which is equivalent to the super energy trick of how many realms of heaven?" Old Xiao Tou had already judged Nangong Jun's strength before, but he still didn't have an accurate comparison.

"The strength of the Earth Field Killer is generally between the strengthening of the Super Energy Vein to the Three Realm Heavens to the Four Realm Heavens, and it is also related to the cultivation advancement of the Super Energy Technique, and it is not completely divided by the Super Energy Vein Enhancement Realm."

"Lao Tzu doesn't believe in evil" At this moment, Yan Lao'er's angry roar came from the stone room, he was trying to break through, but he didn't even shoot down half of the live target.

"Second Boss Yan, I'll help you" Boss Yan also fell into the stone room, and with a wave of his hand, a large wind whirlwind appeared in mid-air, rolling the remaining hanging targets into it.

"Not good!" The sword slave exclaimed: "Breaking through the level with two people will shorten the time to break through the level, and the difficulty of the challenge will also be doubled."

Really! At the moment when Boss Yan threw out the wind whirlwind, seventeen live targets appeared in the sky, and at the same time, the ground and the roof were relatively close, and even the walls were moving, and a large area of hidden weapons roared in.

"Boss Yan, take Elder Yan out" Old Xiao Tou was also shocked into a cold sweat at this time, and shouted loudly.

Whoosh!

The Yan brothers were in the rain of hidden weapons, rolling in embarrassment, dodging, and finally escaping from the entrance and exit in danger.

At this time, the two of them barely had a complete piece of clothing on their bodies, and dozens of wounds were cut through their flesh and skin, and blood was pouring out.

"Boss Yan, don't come in, wait for us outside" Old Xiao couldn't bear to let them continue to take risks.

"Boss, this injury is not a problem, our Yan brothers will definitely not hold you back" Yan Lao Er stepped up, his body shook and turned into a giant and prepared to break through.

Boss Yan also re-activated the Wind Whirlwind Technique, this time, they calmed down a lot with each other, and walked into the stone room in harmony with each other, their movements also became agile and crisp, and they began to bombard and kill thirty-four live targets in the sky.

One, ten, thirty..... This time, they actually knocked out thirty live targets in a row before triggering the mechanism, and the Yan brothers exited the stone chamber in embarrassment.

Seeing this, Lao Xiao Tou and Jian Nu both admired the tenacity of the Yan brothers from the bottom of their hearts, as well as the harmony of their brothers.

"Speaking of conscience, if they hadn't just comprehended the supernatural technique, with their matching, they would definitely be perfect" The sword slave rarely praises people, not to mention that it is still Yan Lao'er, it can be seen that the matching and tactics of the Yan brothers have indeed brought her a lot of shock.

"But they still can't break through..."Old Xiao Tou knew very well what the distance between thirty and thirty-four was, it was like a running champion going to challenge the world record, and every 0.01 second of advance was a miracle.

"Master, maybe this is a rare opportunity for them" The sword slave thought for a while and said, "The Yan brothers have never really practiced the clan combination sniper technique, but they do have the potential to become a combination sniper."

Old Xiao Tou also glanced up, and the Yan brothers, who were in a peak state at this time, also inexplicably agreed with the idea of the sword slave.

Whew! The Yan brothers began to break through for the third time. This time, they seemed to have comprehended it again, and the match was much smoother than the previous two, and the whole movement was like water, and finally knocked out thirty-two live targets.

Seeing this, Lao Xiaotou's eyes lit up, and he secretly thought: "These two guys usually look useless, but I didn't expect that two people together could burst out with such amazing potential."

Time passed bit by bit, the Yan brothers had challenged, frustrated more than a dozen times, and finally knocked down the live target to thirty-three, only one step away, they could successfully clear the level, this last step is as difficult as ascending to the sky.

The Yan brothers have been stuck here eight times, and this is the ninth attempt....

"Sword slave, do you think they will succeed?" Old Xiao's gaze swept over the Yan brothers, who had already overdrawn their potential, and then turned back to ask the sword slave.

"The hosts! Don't worry, the potential of the Yan brothers is definitely more than that, you see that the super energy momentum on their bodies is merging" The sword slave used his hand to a Yan brother, and Lao Xiao looked at it intently, only to see that next to the Yan brother's body, within a small range, the wind element and the earth element were merging.

"This is the beginning of the combined sniper technique, master, congratulations on having two more potential helpers," the sword slave said with a confident smile.

"Momentum melts!" Old Xiao Tou frowned, as if he had thought of a speculation of the rules of superpower, but he couldn't get a glimpse of the mystery for a while.

Rumble! Yan Laoer's body jumped up in the air, and his body rushed straight towards the live target, Yan Lao'er actually rode on Yan Laoer's body, and as soon as he shook his hand, a large piece of wind whirlwind enveloped the live target.

Whoosh! The hidden weapons around him were like rain, Yan Lao Er waved his arm, like a meat shield blocking Yan Boss's side, Yan Boss continued to perform the wind whirlwind technique, grabbed it hard, and his body fell to the ground, and at the same time, one leg swept out, and the powerful wind whirlwind dissolved the remaining hidden weapon rain.

"They succeeded!" The sword slave smiled with a fluttering eyebrow.

"Boss!" Yan Lao Er smashed into his face like a meat egg, knocking Lao Xiao Tou out of dozens of steps in one go.

"Damn, you stuffed the entire passage by yourself, and let no one else live" Lao Xiao slapped Yan Laoer's head on the head, and everyone laughed.

"Boss, I forgot to transform in a hurry, I'm sorry! I'm sorry" Yan Lao Er also had an embarrassed expression, touched his head, and smiled innocently.
