Hua Feifei noticed that the underground structure under the tower was constantly expanding like a spiral, and the further down, the more many passages appeared, extending in all directions, twisting and turning.

Moreover, the labyrinthine building construction corridor is tall and wide, and it is not known who excavated it.

Just as Hua Fei turned into an avenue, boom.

There was a sound of explosions and vibrations ahead, and in the thick of smoke, there was an explosion in front of them.

Hua Feifei quietly went around to the front and found more than a dozen people in front of the passage, these people should be with those outside the tower.

"Commander, this stone gate has exploded three times, and it seems that it can't be blown open!" In the thick fog, someone said.

"Hmph, double it for me, I don't believe it can't be exploded." The head of the mercenary group gave the order.

"Okay." Those subordinates didn't refute more, but quickly arranged double the amount of energy bombs, and they took out pieces of energy explosives from their bags one by one and put them in front of a wide stone door, which was four or five meters tall and looked stone, but Hua Feifei clearly felt a faint chaotic pulse energy surging on the door.

Hua Feifei couldn't help but sneer, this door was obviously not something that energy explosives could blow up.

Rumble.

There was another deafening, earth-shaking explosion.

The cave swayed, looking like it was about to collapse, but it soon stopped, and in front of the tall stone gate there was only a dirt pit, and the gate was still closed.

Seeing that the gate did not move, the head of the regiment seemed to be a little annoyed, grabbed the collar of the person in charge of the blasting and roared.

"Didn't I make you double!"

The man looked extremely aggrieved and said, "I...... I've really doubled, almost tripled. ”

"Add me more." He pushed the subordinate away, looking very angry, and felt humiliated by a door, "Give me all the explosives and grenades thrown in, I don't believe in this evil." ”

"Yes." How dare the subordinate refute, so he had to do it as usual.

After a while, the grenades in the hands of more than a dozen mercenaries and the explosives in their bags were all piled up at the gate, which could indeed overturn a strong fortress.

Everyone dodged the road gate around the road, and followed closely, there was a loud noise.

Rumble!

Gravel continued to fall from the violent cave, and the shaking and shaking were felt for a longer time, and some people were even choked by the violent gunpowder smoke in the thick fog.

The head of the regiment couldn't bear it, and came to the gate in three steps and two steps, and was immediately dumbfounded, and the same was true for the subordinates behind him.

"Regiment, regimental commander...... There's definitely something quirky about this one! The subordinate in charge of the blasting looked at the undamaged gate and felt incredulous.

"The more you can't open it, the more it means that there are great treasures in it." The regimental leader touched his chin, but he was not as angry as he had just now, and he was going to check if there were switches around.

Click.

There was a sound.

Suddenly, all the mercenaries drew their weapons and looked at the back passage, and behind their gate, there were seven or eight holes leading in.

Hua Feifei was also at the entrance of one of the holes, but he didn't make a noise from stepping on anything, obviously, there were other people, so he planned to continue lurking.

Sure enough, at the entrance of one of the holes, a black figure slowly walked out, carrying a black spear.

"Luo Jing?" The head of the regiment naturally recognized the people.

Luo Jing stopped more than ten meters away from these people before leaving, looked around at these mercenaries who were vigilant against them, and said coldly: "If you are interested, get out." ”

Those mercenaries didn't expect the other party to let them roll as soon as they came out, and suddenly they were a little annoyed, and the sound of loading bullets echoed in the hole, obviously using these sounds to fight back against Luo Jing's arrogance.

The mercenary group leader was not afraid of Luo Jing, and said, "Do you think our Huwei mercenary group will be afraid of you?" ”

"Afraid?" Luo Jing seemed to sneer, and the black spear in his hand suddenly surged and flew away like a black poisonous dragon.

The mercenary leader saw the tip of the spear coming through the air, extremely sharp and fast, if he was stabbed, he didn't dare to think that this shot would be able to penetrate his armor vest-

He didn't care about everything, and suddenly drew his war knife, bursting out with all his pulse energy, and the bell bell.

Slashed three times in a row, repelling the opponent's three fierce and tricky gun shadows, and the vigorous black flames exploded on the tip and blade of the gun, but what I never expected was that the opponent's gun shadows appeared endlessly, endlessly, and continued to bombard like a tide.

The mercenary group was trembling in cold sweat at this time, the reason why the other party was called the Yama spear was for a reason, he simply found a flaw in the continuous and fierce gun shadows, and he could only draw his knife and keep defending, but Luo Jing's gun was too fast, dazzling, so that the mercenaries around him looked like Luo Jing was controlling dozens of Yama spears with both hands.

What's more, his figure moved ghostly, and he didn't mean to keep his hands at all.

"Wait...... Wait a minute. The mercenary group hurriedly blocked the momentum and called out.

Luo Jingke didn't mean to stop, the Yama spear in his hand bloomed with a large area of pulse energy flames, bang, bang, the long knife of the mercenary group leader slashed at the Yama spear, bell!

The whole person retreated and flew away, but the tip of the spear was like a sharp sweeping dragon tongue, and it did not give the other party a chance to breathe.

The mercenary group leader popped and exploded three clouds of blood mist, and suddenly his breath weakened, and he retreated suddenly, being held by two subordinates.

"Not yet...... Above! The mercenary leader looked at these waste subordinates and immediately scolded.

Those mercenaries opened fire one after another, and the bullets shot away intensively, smashing around the opponent's gun, Luo Jing calmly retracted the gun, swept the circle to block, and blew up.

Between the shadows of the guns, the energy bullets were constantly being opened.

But the mercenary group glanced up, only to see Luo Jingdian's figure dodging left and right, and suddenly stabbed a subordinate with a spear, the subordinate snorted, and was directly pierced on the huge stone door, and the ones behind him opened fire, he drew his gun to dodge, surrounded like the wind, and the spear in his hand swept past those mercenaries like a spear.

When people flipped on their backs, some people still began to run away.

The mercenary leader looked at the wound on his body, bubbling blood, he gritted his teeth and pulled out the energy stimulant from his backpack and pricked it into his body, and a stream of energy was injected into his body.

But before he could stand up, a spear swept over, hitting him directly in the forehead, and he suddenly fainted, lying on his stomach, the blood under his body was still spreading and expanding, and it would not be long before he would bleed to death.

Luo Jing proudly glanced around with a gun, and found that there was no one standing, so he looked at the location where Hua Feifei was, and the tip of the gun was pointing.

"Come out."

Hua Feifei obviously felt that Luo Jing was talking about herself.

Hua Fei walked out slowly and spread her hands.

"It's you."

Luo Jing saw that it was Hua Feifei, and naturally put down the Yama spear, after all, the two of them were in the woods, and Hua Feifei had roasted meat for this killing god to eat.

"Don't get me wrong, I'm not here to steal any treasures from you." Hua Extraordinary explained.

Luo Jing didn't answer him, but looked at the gate intently, the mercenary who was stabbed to death just now, the blood donation that flowed into slowly activated the formation of this gate, and bursts of strange light were constantly flickering, and those rays of light continued to rotate and twist along the dusty veins of the gate, converging into a magnificent and shining formation, booming, and began to roar and start.

The gate slowly rose, and the dusty gate continued to fall into dust, revealing the environment inside, which was a huge interior space, and behind the gate, a straight hanging avenue was revealed!

Hua Feifei and Luo Jing were a little stunned, Luo Jing took the lead in picking up a gun, Hua Feifei also cautiously followed behind, Hua Feifei noticed that the hanging avenue under his feet was a metal deck made of some kind of metal, they were solid and thick, and the width was several meters thick, even if it was explosives, it could not be easily blown up.

Hundreds of meters of passage, the passage is connected to a circular platform, which is surrounded by four connecting metal deck passages that lead to the rest of the interior.

Hua Feifei noticed that the internal structure here was like a well-equipped laboratory, with a heavy bunker metal deck, as well as various instruments and tubes, and what surprised Hua Feifei and Luo Jing even more was that there were also suspended prototype glass troughs connected by pipes under the metal deck.

In the glass trough, there are colorful culture fluids, which are soaked with strange-shaped plants, and there are some creatures that the two have never heard of and never seen, they are large and small, the small ones are nearly one meter, and the large ones are close to more than ten meters in size, and the glass troughs hanging here are all static, although I don't know how long it has been, but here still reveals the scientific and technological achievements of the brilliant biological civilization.

If these test subjects are obtained by the Free Federation or the Confederate Empire, it is estimated that it will be another technological explosion.

The two of them walked over to the circular table and noticed a desk on the circular table with a spherical instrument on it.

Luo Jing hesitated, and touched the ball with the tip of the gun, and the ball lit up like a sense, and an electronic synthesis sound sounded.

"Hum. Miles, miles, miles. "It makes strange electronic sounds.

"It seems to be talking?" Hua Feifei noticed the other party's audio rules, which were obviously the rules of language.

The instrument seemed to froze, adjusting its voice to emit the human language of the two men.

"I'm the console five operator of Lab 13 in the Tower of Babel. How can I help you? The orb suddenly rose into the air, emitting light and words.

"How do you know our language?" Luo Jing asked with the tip of the gun at the strange metal ball.

"I intercepted the audio of your conversation just now, and I can make out that your language is in the language library." Controller Five said.

Luo Jing glanced at Hua Feifei and didn't speak again.

Babel? Hua Feifei had heard this name in the biblical creation of the previous life, which was the construction of the Tower of Babel by human beings to the heavenly realm, but in the end, human beings failed.

"Who created the Tower of Babel?" Hua Feifei couldn't help but ask with some curiosity.

"It was created by the Creator." Control Number Five said a word of nonsense.

"Who is the creator?" Hua Feifei asked, could the other party be those giant civilization races that have crossed over and sent them here?

If so, perhaps Hua Fei can find a way back to Earth here, after all, the civilization technology of the giant race alone is much more advanced than that of the Free Federation and the Alliance Empire.

The instrument ball spun for a while, and after searching for the answer for a while, there was finally an answer.

Hua Feifei waited for it to answer with hope, and there was a hint of nervousness and excitement.
