Just like a diver under the surface of the sea entering and exiting a submarine, there is a special step to go through. Only by maintaining a balance between the pressure inside the launch tube and the outside of the submarine can seawater not backing up into the submarine.

And now the other party took away the Tianwen Sword, using the same method.

The two layers of spatial barriers alternated with each other, ensuring that when taking away the Tianwen Sword, it was impossible for Qin Xuan to find a gap to break through into the research room.

This also made Qin Xuan deeply understand the awesomeness of scientific researchers, which is simply leaky!

However, after Tianwen Jian was brought into the research room, Qin Xuan's heart relaxed.

These people from the National Security Bureau were not unaware of the terrifying aspects of the Tianwen Sword, even if it was the impregnable spatial barrier in front of them, it could not block the connection between Qin Xuan and the Tianwen Sword.

You must know that the current Qin Xuan is connected to the Tianwen Sword, Qin Xuan is the Tianwen Sword, and the Tianwen Sword is Qin Xuan!

It can be said that the Tianwen Sword is one of Qin Xuan's arms, and Qin Xuan's mind can make the Tianwen Sword burst into murder and be unstoppable.

Now all he has to do is wait.

As long as you thoroughly understand the situation in the underground research room, such as the location of the console that controls the space barrier, you can directly manipulate the Tianwen Sword to destroy it at that time.

"The spatial barrier can block the general magic weapon induction, but it can't block my connection with the Natal Flying Sword......"

Qin Xuan pretended to step back while thinking about it, looking a little desperate.

Obviously, those two middle-aged men didn't know anything like the Natal Flying Sword, their strength was imposed by scientific and technological means, and they didn't know that much about the things in the cultivation world.

After obtaining the Tianwen Sword, the two middle-aged men didn't pay much attention to Qin Xuan at all, and ran inside with the sword.

Qin Xuan was connected to the Tianwen Sword Heart, and he clearly felt the situation in the underground research room, which was divided into several rooms. Xuanyuan Sword Spirit also continued to poke out his divine thoughts, gradually figuring out the situation in these rooms.

Since the laboratory is located underground, and it is estimated that there are very solid walls and floor tiles to block it, the police on the ground cannot get down at all.

Outside the entire research room, only Qin Xuan was left......

"The central room should be a control room, and there are two people in it, a man and a woman, wearing white robes, who should be scientific researchers. ”

The scene that Tianwen Jian felt gradually appeared in Qin Xuan's mind.

"The control location of the space barrier should be in the central control room. There is also a key room, which is where Qin Yu'er is. As long as the spatial barrier is eliminated, go and rescue Qin Yu'er. As for these researchers......"

Qin Xuan thought about it in his heart, and finally decided to spare their lives.

After all, these are all top scientific and technological talents in China, and the one who kidnapped Qin Yuer should only be the chief scientific researcher, and it has nothing to do with other scientific researchers.

It's just that Qin Xuan has patiently observed for so long, but he hasn't found any person in it who looks like the chief researcher.

If it weren't for the other party's first-class camouflage ability, it wouldn't be here.

The two middle-aged men held the Tianwen Sword and ran directly into a scientific research room, handing over the Tianwen Sword to several other white-robed scientific researchers.

The walls of the entire underground research chamber are constructed of unknown silver metal, which appears to be delicate and coordinated.

"There are a total of twelve scientific researchers, and only two combatants. The other six people should all be victims like Yu'er. ”

Soon, Qin Xuan figured out the specific situation.

When Tianwen Jian was sent into an instrument and seemed to be about to conduct a preliminary test, Qin Xuan finally took action!

Swish!

The white light shone brightly, and a sword broke through the air.

Tianwen Sword flew directly to the central control room!

This scene frightened all the researchers in the research room and the control room.

How did this thing suddenly erupt?

It's like being alive!

This was followed by an explosion that rang out from the central control room.

Zizizizi!

As a series of electric sounds came out, Qin Xuan saw that the two circles of spatial barriers in front of him had indeed begun to dissipate. This spatial barrier originally surrounded the entire research room, so Qin Xuan couldn't find a gap to break through it.

But now, the other party can no longer stop him!

The precision instruments in the central control room have been smashed into a piece of scrap copper and rotten iron by the Tianwen Sword, and no matter what means the other party uses to create a space barrier, it will not appear again now.

Qin Xuan made a move at that time, dodged, and directly teleported to the medical room where Qin Yu'er was.

The structure of the research room is still very sophisticated, although the central control room was destroyed and the power supply could not be supplied, but the backup power was quickly activated in this medical room, and the white light illuminated the entire medical room.

On the precision stretcher instrument that appeared in front of Qin Xuan, there were six lying people, one of whom was Qin Yu'er.

"Who are you to break into the research office of the National Security Bureau!"

A middle-aged man in a white coat immediately shouted out in the medical room, and three scientific researchers in the medical room surrounded him at the same time.

"Oh? Don't you know me. ”

Qin Xuan smiled slightly, and with a wave of one hand, the three of them were immediately unable to move!

Then he glanced at Qin Yu'er, only to see her lying on a precision stretcher instrument, combing two lovely long braids, and closing her eyes.

It seems that the reason why he was just sent in was that he was not attached to the instrument catheter like the other five people, but was just placed on a stretcher at random.

Seeing that she was fine, Qin Xuan breathed a sigh of relief.

The three researchers couldn't even speak, and their eyes were full of horror. Now in this situation, seeing Qin Xuan's outfit and dress, how could they not know that they had met a real awesome cultivator this time?

There is no doubt that this is the Qin Xuan that the top wants to attract!

"Look for death!"

An angry roar came from the side, and the middle-aged uncle from before finally rushed over from the other room, and with a wave of one hand, a spatial crack formed a blade and flew towards Qin Xuan!

"It's too weak. ”

Qin Xuan shook his head, and one dodged to the middle-aged uncle's side, grabbed it with one hand, and the Tianwen Sword appeared in his hand out of thin air, and then swung it.

Swish!

Bang!

This middle-aged uncle was directly turned into pieces by the power of the Heavenly Dao!

Although such an ability fighter has a great advantage compared to cultivators below the realm master, once he encounters the real realm master, he will only be ravaged.

"There is no need for this research room to exist. ”

Qin Xuan turned his head to look at the stretcher instruments in the medical room, his expression was cold, and he asked the three medical personnel, "Are the people here all right?"

Watching the middle-aged uncle be instantly turned into pieces and disappear into this world, where did the three medical personnel dare not tell the truth?

Immediately, the middle-aged white coat led by him hurriedly said: "It's okay, it's okay, this batch is only conducting physical testing, and there is no injection of special potions......"

"Since I'm here, I'll save you by the way......"

With a wave of one hand, Qin Xuan directly let Qin Yu'er and the other five people float up from the stretcher instrument, including Ning Xiaoxue.

Just as he was about to leave with them, another middle-aged man finally appeared at the door of the medical room, with spatial power!

"Death to those who stand in the way!"

Qin Xuan coldly raised the Tianwen Sword.
