Chapter 406: Tunnel under the tunnel

Meng Chao smelled a damp and rancid smell.
It's like the methane pouring out of the swamp deep in the primitive jungle.
Biogas is not only highly toxic, but also easy to
"call!"
Zhou Tianshui was poked into a hole like a balloon, and his body shrank by nearly a third in an instant with the gushing of "methane".
In the next second, the "marsh gas" that he spewed violently exploded, and a green flame rose into the air, almost covering half of the street.
All the glass windows on both sides of the street shattered.
Meng Chao was also blown away more than ten meters by the shock wave.
The retina was in contact with the burning biogas, unspeakably hot and swollen, and his vision became blurred again.
After rubbing my eyes for a long time, I found that the explosive "marsh gas" had turned into specks of ghost fires, and the ghost fires were flying around. How could there be the shadow of Zhou Tianshui?
Lu Siya finally caught up.
"Lost chased?" she asked.
"Lost." Meng Chao said.
"He is not suspicious, right?" Lusiya asked again.
"Believe in my acting skills, he must feel that he escaped by his own ability." Meng Chao smiled slightly.
Lu Siya nodded, took a deep breath, and squinted her eyes and said: "I've seen his escape route."
"Fortunately, I configured a special tracking potion, which 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.
Just now, he analyzed with Lu Siya that Zhou Tianshui's inner ghost could not have mobilized so many monster forces to plan the entire "acoustic attack, precise raid" operation behind the scenes.
Even if it was taken on the spot, he might not be able to ask any key information from him.
Now that Dr. Lu Tianxing's life or death is uncertain, and the "master brain" of the alien beast has not surfaced, it is better to put a long line to catch the big fish and deliberately let Zhou Tianshui go to see if he will find the master brain of the alien beast to converge.
Therefore, when the two of them crossed their arms, without knowing it, Meng Chao smeared the tracking potion on Zhou Tianshui.
This special tracking potion contains red radiance jade and blue protolith powder, and is mixed with some "swamp demon lizard" slime.
Since being severely bombarded by the Red Jade Frenzy at the bottom of the Fury Mountain Range, he has escaped by hiding in the blue original mother stone mine.
Meng Chao and Lu Siya became particularly sensitive to these two spars.
They can perceive any material, even if there is a little bit of red jade powder in it.
The "Swamp Demon" is a very interesting monster.
The body strength is not strong, even the Nightmare Fierce Beast is not even considered, but it has special skills to confuse and deter enemies.
It can secrete dozens of different mucus, exuding the smell of nightmare beasts and even beasts.
Applying this kind of slime to leaves and shrubs, you can disguise your habitat as a nest of fierce beasts, so that ordinary monsters dare not approach.
And its own breath has an indescribable smell that humans can smell after special training even if it is diluted ten thousand times.
Meng Chao is a reaper, and Lu Siya is a sensitive person. She is no stranger to the smell of the swamp demon lizard. After receiving a period of intensive training at the Bureau of Foreign Animals Investigation, she can infuse her psionic energy on the nasal mucosa. The extremely developed sense of smell accurately locks the smell of the swamp demon lizard.
Coupled with their induction of the red sapphire veins and the blue original mother stone, this kind of Meng Chao personally modulated, only the two of them, plus at most one tracking potion that Qin Hu can perceive, which is better than the ordinary tracking produced by the Alien Beast Investigation Bureau. The agent is much more secretive and much more effective.
Originally, the purpose of Meng Chao's preparation of this tracking agent was to catch the super sandworm.
Unexpectedly, accidental hits and collisions are used here.
Zhou Tianshui thought he had escaped.
As everyone knows, his escape route is like a set of shiny road signs in the eyes of Meng Chao and Lu Siya.
"Let's go to inform the top and find more powerful people to help." Lu Siya said.
"No, let me know, one person is enough, I will catch up first."
Meng Chao explained, "The tracking potions I just applied to him just now are not many. If he escapes into the ground and the tracking potions are exhausted, then he won't be able to steal the rice.
"And I have sprayed a lot of tracking potions on myself, enough to consume an hour or two.
"Therefore, I have to bite his tail all the way, so that it will be easier for you to catch the mastermind behind the scenes!"
Lu Siya originally wanted to stop, 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 die. From this posture, the'mastermind' of the alien beast might reach the'doomsday level', and even the strongest of the heavens can't deal with it. It's definitely not your small pinnacle. , It can be resolved."
Lu Siya said, "I'm going to find the team leader now and mobilize more masters, including the team leader's brother, Ye Xiaoyue, the powerhouse of the gods, the "Remnant Sword" to come to you.
"Don't worry, I don't die that easily." Meng Chao smiled confidently.
I secretly added a sentence in my heart-before the end is crushed, I will never die!
He followed the traces left by Zhou Tianshui and hurried to catch up.
Going around the corner, the trace turned ninety degrees, appeared on the facade of the building, and then disappeared into a window.
Obviously, Zhou Tianshui climbed up this building and jumped into the window.
If you don't track down the potion, if you chase straight down the street, you will lose it in all likelihood.
Meng Chao followed Zhou Tianshui's route, walked through the building from inside, and jumped down from the window on the other side.
Just below is the entrance and exit of a subway station.
A monster attacked tonight.
The entire city's subways, except for some military lines used to quickly mobilize troops, all civilian lines are suspended.
This subway station is no exception.
When Meng Chao stepped forward to look, he found that the iron fence was pulled down at the entrance, and the ground lock had been broken.
Someone broke the ground lock, pulled up the iron fence, got in, then pulled down the iron fence, and re-disguised as if the subway was closed.
"right here."
Without hesitation, Meng Chao pulled the iron fence and got in.
He jumped down the stairs in two steps, jumped over the turnstile, and came to the platform, where he found traces of the opponent, extending all the way to the depths of the tunnel.
Raising his vigilance and following the traces, Meng Chao went more than ten meters deep into the tunnel along the railroad tracks, and the traces turned into the maintenance corridor beside the tunnel.
Meng Chao held his breath and gently pushed open the door of the maintenance passage.
Inside, there was a piece of black and black, and he could not see his fingers. Meng Chao simply closed his eyes and scanned with psychic energy to outline a large number of pipes, cables and maintenance tools.
In the darkness, the spiritual flames emitted by the powder of the red radiant jade and the blue original mother stone seemed to be a beacon that flickered and directed his direction.
Meng Chao came to the end of the maintenance tunnel, removed two toolboxes, and found a hole had been cut in the wall.
Behind the hole is a vertical downward ventilation shaft.
The black black seems to lead directly to the Yincao netherworld.
Meng Chao turned his head and glanced behind him.
I found that I had left traces ten times brighter than Zhou Tianshui.
Lu Siya should be able to bring dozens of realm powerhouses, hundreds of sky realm masters and a million red dragon army in time, right?
Thinking of this, he bent his mind, drilled into the ventilation shaft, used both hands and feet, and climbed down.
This ventilation shaft is extremely long and deep, as if it never ends.
Judging from the repair of the wall, it does not look like a hole made by sandworms, but rather carefully constructed by humans.
Finally climbed to the bottom of the ventilation shaft, drilled through a horizontal ventilation duct, and there was another collapsed tunnel outside with twisted railroad tracks.
This "tunnel under the tunnel" is darker than the maintenance access above, like being on the seabed several kilometers deep.
Meng Chao used psychic energy to scan the surroundings and found that not far away, under the collapsed rock, was buried a fragmented subway.
Looking forward, I found that the subway was the style of the earth age half a century ago.
It seems that this tunnel is a subway line that exists on earth.
When Dragon City passed through, this tunnel also passed through.
However, because of being at the edge of the crossing range, the space was distorted, the tunnel collapsed, and it was abandoned and gradually forgotten.
For snakes, insects, rats and ants who are good at working underground, this is the best secret passage.
Meng Chao got into the gap between the collapsed rocks and jumped into the abandoned subway from the front of the car.
He was walking through the subway car and scanned many skeletons on his seat.
Accidentally, there was a slight "click" under my feet, but a few bones were broken.
At the moment the crossing occurred, this subway line was still in operation. Many passengers were sitting on the subway and crossed to another world in a daze. Before they could react, they encountered space distortion and tunnel collapse accidents, and died deep underground.
Crossing is really not fun.
Meng Chao sighed and became more careful, avoiding the bones of his compatriots half a century ago.
Suddenly, he stood still in the middle of the penultimate carriage.
Zhou Tianshui's trace 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 squinted his eyes and scanned the surrounding area vigilantly.
Behind him, there was a soft bone cracking sound, "click".
He didn't hesitate, a "scorpion wagging its tail", in the middle of a tuft of something like leather.
The thing fell out, but didn't even hum, and rushed up again with ten times more ferocious aura.
Is it... Zhou Tianshui?
In the small subway car, neither long gun nor short cannon can be used. When the two sides meet, it is a hand-to-hand battle.
Meng Chao slammed over his shoulder and slammed the opponent to the ground.
Obviously, he has controlled his hands and legs, and a strong wind is still blowing behind him.
With a "pop", Meng Chao's spine was hit hard, and he staggered forward and flew out.
When he looked back, he saw a humanoid monster.
The monster's face still looks like Zhou Tianshui.
The cheeks, chin, limbs and torso were covered with a layer of bronze scales.
On the sides of both arms, sharp bone spurs protruded violently.
Both hands became sharp claws.
A scaly tail was dragged behind.
