Oh My God! Earthlings are Insane!

Meng Chao smelled a damp and rancid smell.

It's like the swamp gas gushing out of the swamp in the depths of the primeval jungle.

Methane gas is not only highly poisonous, but also easily-

"call!"

Zhou Tianshui seemed like a balloon had been poked with a hole, and with the gushing of "methane gas", his figure instantly shrunk by nearly one-third.

In the next second, the "marsh gas" he gushed out violently deflagrated, and green flames soared into the air, almost covering half of the street.

All the glass windows on both sides of the street were shattered.

Meng Chao was also blown away more than ten meters by the shock wave.

The retina was in contact with the burning methane, and it was indescribably hot and swollen, and the vision became blurred again.

After rubbing my eyes for a long time, I found that the detonated "methane gas" had turned into dots of will-o'-the-wisps, and the will-o'-the-wisps were flying around. How could there be Zhou Tianshui's shadow?

Lu Siya finally caught up.

"Lost it?" she asked.

"I lost it." Meng Chao said.

"He's not suspicious, is he?" Lu Siya asked again.

"Believe in my acting skills, he must think that he escaped by his own ability." Meng Chao smiled slightly.

Lu Siya nodded, took a deep breath, narrowed her eyes and said, "I've seen' his escape route."

"Fortunately, I prepared a special tracking potion. It was originally prepared for the super sandworm 'Gao Ye', but I didn't expect it to be used on this kid." Meng Chao was grateful.

He analyzed with Lu Siya just now that an insider like Zhou Tianshui couldn't possibly be the mastermind behind mobilizing so many monster troops to plan the whole "Shock East West, Precise Raid" operation.

Even if it is won on the spot, it may not be possible to get any key information from him.

Now that Dr. Lu Tianxing's life and death are uncertain, and the "mastermind" of the alien beast has not surfaced, it is better to go for a long line to catch a big fish and deliberately let Zhou Tianshui go to see if he will meet with the mastermind of the alien beast.

Therefore, when the two of them crossed their arms, Meng Chao smeared the tracking potion on Zhou Tianshui's body without anyone noticing.

This special tracking potion contains ruby ​​jade and blue mother stone powder, and is mixed with some "swamp monster lizard" slime.

Since he was severely bombarded by the Honghuiyu frenzy at the bottom of the Raging Wave Mountains, he was lucky enough to escape by hiding in the blue original mother stone mine.

Meng Chao and Lu Siya became particularly sensitive to these two crystals.

They can sense even a little bit of red jade powder in any material.

And the "swamp lizard" is a very interesting monster.

The actual strength is not strong, not even a nightmare beast, but it has special skills to confuse and deter the enemy.

It can secrete dozens of different mucus, exuding the smell of nightmare beasts and even hell beasts.

Applying this slime on leaves and bushes can disguise one's habitat as a beast's lair, preventing ordinary monsters from approaching.

And its own breath has an indescribable fragrance. After special training, humans can smell it even if it is diluted ten thousand times.

Meng Chao is a reaper, Lu Siya is a sensitive person, and they are no strangers to the smell of swamp lizards. After receiving a period of intensive training at the Alien Beast Investigation Bureau, as long as they infuse spiritual energy on the nasal mucosa, they can have With an extremely developed sense of smell, it can accurately lock the taste of the swamp monster lizard.

Coupled with their sensitivity to the red jadeite vein and the blue original mother stone, this kind of Meng Chao prepared it himself, only the two of them, plus at most one tracking potion that Qin Hu can perceive, which is better than the ordinary tracking potion produced by the Alien Beast Investigation Bureau. Potions are far more subtle and effective.

Originally, Meng Chao prepared this tracking potion to catch super sandworms.

Unexpectedly, it was used here by mistake.

Zhou Tianshui thought he had already escaped.

Little did they know, his escape route was like a set of shining road signs in the eyes of Meng Chao and Lu Siya.

"Let's go and notify our superiors to find more powerful people to help," Lu Siya said.

"No, inform the superiors, one person is enough, I will catch up first."

Meng Chao explained, "The tracking potion I just applied to him is not much, if he escapes into the ground and the tracking potion is exhausted, it will be a waste of money.

"And I have already sprayed a large amount of tracking potion on myself, enough to consume it for an hour or two.

"So, I'm going to bite his tail all the way, so that it's easier for you to catch the mastermind behind the scenes!"

Lu Siya originally wanted to stop her, but after thinking about it, she closed her mouth again.

Having known each other for so long, she knew that Meng Chao was not someone who could be easily stopped.

"Then be careful, don't play dead. Judging from this posture, the "mastermind" of the alien beast might reach the "doomsday level". , can be resolved."

Lu Siya said, "I'm going to find the team leader right now, and call more experts, including the team leader's brother, the god-level powerhouse 'Canjian' Ye Xiaoyue, to come to you."

"Don't worry, I won't die that easily." Meng Chao smiled confidently.

I secretly added a sentence in my heart-I will never die until I smash the doomsday!

He followed Zhou Tianshui's traces and quickly chased after him.

Around the corner of the street, the trace turned ninety degrees, appeared on the facade of the building, and then disappeared into a window.

Obviously, Zhou Tianshui climbed up the building and jumped into the window.

If it weren't for the tracking potion, if you chased straight along the street, you would probably lose it in all likelihood.

Meng Chao followed Zhou Tianshui's route, passed through the building from the inside, and jumped out of the window on the other side.

Just below is the entrance and exit of a subway station.

There are monsters attacking tonight.

All the subways in the city, except for some military lines used to quickly mobilize troops, all civilian lines are out of service.

This subway station is no exception.

When Meng Chao went up to look, he found that the iron fence at the entrance had been pulled down and the ground lock had been twisted.

Someone broke the ground lock, pulled up the iron fence, got in, pulled down the iron fence, and re-disguised the closed subway.

"right here."

Meng Chao pulled up the iron fence without hesitation and got in.

He jumped down the stairs in two steps, jumped over the turnstile, came to the platform, found traces of the other party, and extended all the way to the depths of the tunnel.

Raising his vigilance and following the traces, Meng Chao walked a dozen meters into the tunnel along the rails, and the traces turned into the maintenance passage next to the tunnel.

Holding his breath, Meng Chao gently pushed open the door of the maintenance passage.

It was so dark inside that he couldn't see his fingers. Meng Chao simply closed his eyes and scanned with psionic energy, outlining a large number of pipes, cables and maintenance tools.

In the darkness, the spiritual flames emitted by the red jadeite and the blue mother stone powder seemed to be flickering beacons, guiding him in the direction to go.

Meng Chao came to the end of the maintenance passage, removed two tool boxes, and found a hole had been cut in the wall.

Behind the hole is a ventilation shaft that descends vertically.

Heiququ seems to lead directly to the underworld.

Meng Chao turned his head and glanced behind him.

He found that he had left traces ten times "brighter" than Zhou Tianshui.

Lu Siya should be able to bring dozens of god-level experts, hundreds of heaven-level masters and millions of red dragon troops to find here in time, right?

Thinking of this, he shook his head, got into the ventilation shaft, and climbed down using both hands and feet.

This ventilation shaft is extremely long, extremely deep, and seems to never end.

Judging from the repair of the wall, it doesn't look like a hole made by sandworms, but carefully built by humans.

Finally climbed to the bottom of the ventilation shaft, drilled through a horizontal ventilation pipe, and outside was another collapsed tunnel, with twisted rails still laid in the tunnel.

This "tunnel under the tunnel" is darker than the maintenance channel above, like being on the seabed thousands of meters deep.

Meng Chao scanned his surroundings with his psychic energy, and found that not far away, under the collapsed rocks, was a fragmented subway buried.

Going forward to check, I found that the subway was half a century ago, the style of the earth age.

It appears that this tunnel is a subway line that already exists on Earth.

When Dragon City crossed, this tunnel also passed through.

But because it was at the edge of the traversal range, the space was distorted, the tunnel collapsed, and it was abandoned and gradually forgotten by people.

For snakes, rats, and rats who are good at moving underground, this is the best secret passage.

Meng Chao got into the crevice of the collapsed rock and jumped from the front of the car into the abandoned subway.

He walked through the subway car and scanned many skeletons on the seats.

Accidentally, there was a slight "click" sound under his feet, but a few bones were crushed.

The moment the crossing happened, the subway line was still in operation. Many passengers took the subway and traveled to another world in a daze. Before they could react, they encountered space distortion and tunnel collapse accidents, and died in the depths of the ground.

Traveling is really not a fun thing.

Meng Chao sighed inwardly, and became more careful, avoiding the bones of his compatriots from half a century ago.

Suddenly, he stood in the middle of the penultimate carriage.

No trace of Zhou Tianshui disappeared.

From the front of the car to here, there have been faint traces on the ground.

Although the breath is getting thinner and thinner, it won't dissipate in an instant.

Meng Chao narrowed his eyes and scanned his surroundings vigilantly.

Suddenly there was a soft bone shattering sound behind him, "click".

Without any hesitation, he hit a "scorpion wagging its tail" and hit something that looked like leather.

The thing fell out, but without even a snort, it charged back up ten times more ferociously.

Is it... Zhou Tianshui?

In the narrow subway car, the long guns and short cannons cannot be used. When the two sides fight each other, it is a hand-to-hand combat.

Meng Chao fell over his shoulder and knocked the opponent hard to the ground.

He had clearly controlled his hands and legs, but there was still a gust of wind blowing from behind.

With a "pop", Meng Chao's spine was hit hard, and he staggered forward and flew out.

Looking back, he saw a humanoid monster.

The face of the monster still looked like Zhou Tianshui.

On the cheeks, chin, limbs and torso, there is a layer of bronze-colored scales.

On the sides of both arms, sharp bone spurs protruded.

Both hands turned into sharp claws.

There is also a scale-covered, meteor hammer-like tail trailing behind it.
