The end of the world: Build a top-level shelter at the beginning

"In the underground flow channel, how can there be such a strong energy reaction?" Li

Xiao couldn't help but be a little surprised.

When he chose the location of Mithril City, he had conducted a comprehensive exploration here.

After making sure that there was no risk, Mithril City was established in this position.

Moreover, Xiaobai's aura defense system did not even find the slightest clue.

It wasn't until they dug the tunnel and saw the underground river that it came to light.

Li Xiao immediately jumped down and fell into the tunnel.

In this case, use the straight sword alone, once you encounter the C rank.

If it's just one, it's okay, the level of the straight sword is also C-level, and the energy limit that can be carried is C-level, plus Li Xiao personally manipulated it, it is not difficult to win.

But once you encounter more than one C-level, not to mention the straight sword hitting the grass and scaring the snake, the straight sword itself may be destroyed.

Therefore, it is more reliable to come down on your own.

After falling straight into the pit.

The Mithril Guards weren't idle.

Yu Hong first asked the drone group that had been prepared before to follow behind Li Xiao.

"When I used the drone to explore before, I just entered the tunnel, and the signal would be lost, and now I don't know what the result will be..."

After the drone fell into the tunnel, they were shocked to find that the signal was lost again!

Yu Hong immediately became nervous

, "Contact the city lord quickly!" "Sir, the signal of the city lord has also been lost!"

"How come? Can Director Bai contact the city lord?".

Under normal circumstances, even if the crystal nucleus communication is disconnected, as long as Xiaobai is locked, it can still provide certain information services.

But Xiao Bai's prompt words were immediately displayed on their terminals

: "The signal is lost!" Yu Hong was stunned, "What is the situation? Why has even Director Bai lost the signal?"

He immediately called up the rest of the tools: "Move those things over and try them, if you still can't get in touch..."

As a leader, he knew he had to make a statement.

Once he had lost his confidence, the Mithril Guard could soon be in a mess!At the

same time, he hurriedly contacted the two captains.

On weekdays, Captain Liu and Captain Zhang are each in charge of different areas of Mithril City.

They don't get together unless they have a major problem.

But today's problem is already serious!

He was still contacting the other two captains, and the Mithril Guard on the side had already retrieved the previous equipment.

Start trying them one by one.

And the result also appeared quickly: without exception, all ended in failure!

Yu Hong's eyes suddenly widened a little, and he secretly sweated, if something happened to the city lord in the dark river.

That's a big problem!!

Li Xiao's side.

He fell straight into the tunnel, unaware that his connection to the Mithril Guard had been lost.

Of course, with his strength, even if he knew, he wouldn't care.

For the exploration of similar areas, Li Xiao is still relatively experienced.

The results of Xiaobai's previous exploration showed that the energy fluctuations coming from inside were only C-level.

And Xiaobai's level of exploration, Li Xiao still believes in it.

He himself had tried to disguise himself as a B-class, but under the aura defense system, he was still detected.

Since the energy fluctuation in this is only C-level, the possibility of camouflage can basically be ruled out.

As a real B-level awakener, Li Xiao certainly has nothing to fear.

Continuing for some distance, the pattern of the underground area does not seem to change.

At the bottom is still a rushing river, and on both sides of Li Xiao, there are still smooth rock walls.

He took out an E-class crystal nucleus and drove the energy contained within it, and the bright light suddenly illuminated the underground area.

"This seems to be a passage?" Li Xiao judged based on his surroundings.

And the results of the advance also verified his guess.

The surrounding cliff walls began to shrink and became a passage that could only accommodate one person.

The clear and cold water had already overflowed Li Xiao's shoulders at this time.

There is a straight sword to explore the way not far ahead, and Li Xiao is also more cautious in moving forward.

After a short time, he followed the passage and came to a door,

which was about three meters high and two meters wide.

At this point, a slit was exposed.

And the surging dark river comes from this!

"Interesting..."Li

Xiao looked at the gate, controlled the straight sword, and was about to break open the gate.

On the smooth gate, special lines lit up in an instant

! It was a complex pattern outlined by mysterious symbols, and a snake biting its own tail was clustered in the middle!

"Damn..."

Li Xiao burst a sentence, the snake bit his tail, it was a cycle, and the gate like the source gave him an ominous premonition.

Immediately withdrawing and retreating, the straight sword slammed forward!

Boom!

The electric current that exploded in an instant evaporated a large area of water.

Li Xiao separated the waters on the side in advance, and there was no electricity to him.

However, the tremendous impact force formed by the instantaneous vaporization of the majestic water flow could not have any effect on the surroundings!

In the stone gate that leaked a crack, a light suddenly cast out.

It just shone on the straight sword.

Immediately, the scene in front of Li Xiao's eyes actually began to "regress"!

The thunder escaping from the straight sword was returning to the straight sword in a countercurrent attitude, and the water curtain that exploded around it was also closed at the same time

! The scene in front of him seemed to have returned to a few seconds ago

! And the water area separated by Li Xiao was not affected in any way!

"Obviously it is only C-level, but it can do such a mysterious thing..."

Li Xiao muttered, and his sharp eyes soon found that after this light came out of the door, the crack in the door seemed to converge a little.

It's useful... Li Xiao's eyes lit up.

Since it has an effect, it may be possible to directly close this door again!

He once again spread out his spiritual power.

I want to reconnect with Straight Sword.

However, at the moment when his mental power was about to establish a connection with the straight sword.

An electric shock-like feeling came

! It was as if he had touched a weapon that had been locked, and was counterattacked by the opponent's spiritual power, thus stabbing him!

Li Xiao's eyes froze, and his gaze was firmly fixed on the straight sword in front of him.

Above the straight sword, countless pitch-black silk threads poured out from the inside of the crack in the door.

They converge quickly.

At a speed visible to the naked eye, it converged into an arm at the hilt of the sword.

Immediately after, a complete human figure appeared!

He went from pitch black to dyed.

Holding a straight sword in his hand, he looked at Li Xiao with emotionless eyes! The figure that suddenly appeared in front of him was exactly the same as Li Xiao himself

! The clone said indifferently: "Disturb the sleep of the door, damn it!" Immediately

, without waiting for Li Xiao to say anything, the clone rushed over with a straight sword

! Rao is separated by a layer of water curtain, and the speed of the clone

is not slow at all! It seems

that he is not affected by the water flow at all!

Li Xiao clasped his hands weakly, and the water curtain in front of him was instantly squeezed together.

A deep blue wall of water is formed.

The clone swung his sword and stabbed at the wall of water.

But the wall of water was unmoved.

See this scene.

Li Xiao smiled!

, "Sure enough, it's just C-grade...", he relaxed a lot.

At first, when he saw the way the clones appeared, he thought how strong they would be.

It can be tested and confirmed to be only C-level strength.

Then he won't be afraid

! Immediately, Li Xiao's eyes froze, and he manipulated the water flow in all directions of the clone, and condensed it into a "wall of water"

! Under the huge pressure, it instantly retracted

! Boom

! A piercing roar came instantly, and the water curtain around the shock retreated several meters!

And the clone also dissipated directly under this blow.

The straight sword was still quietly suspended in place, but before Li Xiao could make any moves.

The door with intricate patterns in front of it opened faintly.

A pitch-black figure quickly took shape, and then dyed in front of Li Xiao.

It's an identical replica again

! In Li Xiao's perception, the strength of this replica is a little stronger than before!

No...

If

the attack continues, then it will be worth paying off? If the attack becomes stronger and stronger, and the cycle continues, then it will be worth paying back?

Thirty-six plans are the best ones

Li Xiao thought for a moment and felt that he could explore it later, of course, provided that he could go...

Without waiting for the clone to rush up, Li Xiao turned around smoothly and left quickly

! Whoosh!

The surrounding water was swept away by Li Xiao, and the passage in front of him became the same as when he came.

The surrounding stone walls began to roughen and widen.

The water that had overflowed over the shoulders had now regained its distance and turned into a dark river surging underground.

flew for a while, but Li Xiao did not encounter the exit.

On the contrary, the surrounding cliff wall became narrow again, and the surrounding area gradually turned into a passage again...

Li Xiao: "???"

forcibly creates a cycle, which is afraid that it has already exceeded the range that C-level can do!

This gate is getting stronger and stronger, and the actual strength exceeds that of C-level?

When Li Xiao was thinking, he was in the tunnel ahead.

The clone rushed out

, clutching Li Xiao's straight sword, and stabbed straight towards Li Xiao.

Li Xiao raised his hand and slapped it, dodging the blade, and then quickly took two steps forward.

After he took a step, the clone drew a straight sword and stabbed twice in a row, but Li Xiao avoided it.

After pulling away again, Li Xiao stared at the clone and didn't move.

The clone held the straight sword in his hand and pounced towards Li Xiao again.

"There is no long-range attack means

...""It seems that it is just a copy of the appearance, and he doesn't have my ability..."Li

Xiao calmly analyzed while dodging the attack.

The strength of this replica is still at the C level.

Even if his strength has improved a little, in front of Li Xiao, he still has no deterrent power.

Looking at his attacks, he was dodged by Li Xiao one after another.

There was a hint of annoyance on the expressionless face of the clone: "The sleep of the intrusion door is not yet dead!" "

Heh..." Li Xiao laughed disdainfully, and his spiritual power instantly manipulated the water flow and locked the clone firmly.

I was trying to trap the clone directly.

Li Xiao found that the clones had turned into pitch-black fluids again, avoiding the cage of his spiritual power condensation.

This guy gave up his straight sword, clenched his fists, and rushed towards Li Xiao again.

"It's only hand-to-hand combat, it's too flawed, and although it can avoid control, it's not very useful.

Muttering, Li Xiao manipulated the water flow and rolled the clone aside.

He himself grabbed the straight sword and slashed it vertically at the surrounding cliff wall!

The moment the gap was formed, in Li Xiao's perception, the clones on the side were also a little weaker.

Inexplicably, a scene appeared in front of Li Xiao's eyes:

the gate with a strange symbol suddenly closed a little

! "I see..."The

clone condensed by the gate attacked itself as soon as it appeared, but in fact it was luring itself to make a move!

The clone whose strength was a big realm worse than himself was certainly not Li Xiao's opponent.

And once Li Xiao exterminated the clone once, the door would be able to open a little.

At the same time, the strength of the clones will also increase a bit.

If Li Xiao hadn't stopped in time at that time, he would have looked for a new way.

Then it is likely that the door will open wider and wider, and the strength of the clones will also increase.

In the end, maybe it will reach a situation where Li Xiao will go all out and can only draw...

When the time comes, it will be difficult to say what accidents will occur....

Li Xiao figured out the key, and raised his hand to launch a continuous attack.

At this time, the clone on the side suddenly began to taunt: "You only have this bit of strength? The water flow can't trap me!" He

took advantage of this time to touch Li Xiao's side, but he didn't attack, as if giving Li Xiao time to react, and slowly walked over!

Li Xiao was about to control the clone casually, but suddenly stopped his movements.

The clone did not attack, but opened his mouth to taunt to attract attention, and its purpose was probably to let Li Xiao attack.

Immediately, Li Xiao retreated a few meters, and before the clone could catch up, he struck a sword at the wall again

! Boom!

A violent roar suddenly sounded, and the water flowing in the dark river began to dissipate.

The clone looked at the scene in front of him in amazement, and then looked at his palm, but it could only follow the flow of water, slowly dissipating.

And in Li Xiao's perception, the door was finally completely closed.

The strange lines that glowed from above were gone.

It was turned into a glittering gate again.

And the scene in front of Li Xiao's eyes also changed again, and the dark river and the tunnel disappeared.

The cliff in front of him turned into a closed door.

There are also two sword marks on it!

Li Xiao raised his head and saw the night sky along a passage.

At the same time, he also sensed the members of the blue sky who were busy above the passage.

"It's solved!" Li

Xiao breathed a sigh of relief, if this gate was discovered, Mithril Guard didn't inform Li Xiao as soon as possible.

By the time he knew, the door would have been wide open, and

it would be too late.

Thankfully, that won't happen again.

At this time, the Mithril Guard above also discovered the passage anomaly.

"City Lord, City Lord is out!"

exclaimed, and the eyes of the surroundings suddenly fell on him.

Li Xiao immediately walked out of the cave and landed smoothly on the ground.

Yu Hong, who had been waiting for a long time, asked, "City Lord, how is the situation?"

Li Xiao responded.
