The smell of rats.

The first time Zhang Qingyang had an entanglement with the Rat God Society was in a similar underground cave.

Every time he thinks about that experience, he can't help but feel a throbbing in his heart.

It's not just a test of life and death crisis, but the most exciting thing is the tens of thousands of rats, squeaking and screaming, overwhelming the world endlessly.

His unique breath of life and countless faint rat consciousness converged into a greedy and brutal powerful biological will field, which invaded his rational thinking and corroded his heart and mind all the time.

People always remember the first time vividly, at that time Zhang Qingyang had not experienced a real sense of adventure, in a sense, the power gathered by those little mice was more shocking than the sandworms brought to him later.

It is a powerful divine power from the Rat God, representing its unique rule will, and if it is affected too deeply, it will become the last appearance of the Liao Hu brothers - the two-faced rat man.

Unless you become a member of the Rat God Society and become the slave and spokesperson of the Rat God, you can avoid that kind of evil result, but the price is to lose your independent existence as a human being, the upper limit is completely stuck, and you lose the infinite possibilities of the future.

This was unacceptable to Zhang Qingyang, so he fought uncompromisingly.

Now, he smelled the smell of rats again.

The smell of the air blowing from the doorway means that the place leading to it is a place similar to the Ten Thousand Rats' Cave, and it also indicates what is about to happen.

Zhang Qingyang sighed in his heart, but he didn't hesitate, just after the turbid airflow eased down, he took a deep breath, completed the integration with the Titan Cat, and bent his hook claws popped out with both hands, and passed through the gap on one side and broke in.

His vision automatically switches to adapt to the changes in the light around him, allowing him to see the inside of the house at a glance without hindrance.

The soil layer on the walls of the old houses that has been uninhabited for many years has been cracked and peeled off, there are traces of water stains seeping into the erosion in the broken corners of the walls, and broken furniture is piled up in the corners, and the surface is covered with thick dust.

Perhaps because of the impact of the air flow just now, a large amount of dust was still floating one after another, Zhang Qingyang shook his fur slightly, and the slight disturbance generated swept away the falling dust, ensuring that there would not be a trace of contamination on his body.

After doing this, he immediately noticed an anomaly in the room.

One is that there are no insects or creatures in the house, snakes, insects, rats, ants, spiders, cockroaches, etc.

The second is the dust on the floor, which is noticeably thinner than the furniture.

In the former vision, he guessed the answer with a twist of his mind.

To explain with common sense, for example, a house that is inhabited by people can last for a long time, and an uninhabited house will soon decay or even collapse, in addition to the reason for human repair, it is more because people, as a powerful dominant life, will naturally change the overall energy field of the living environment, so that low-level creatures feel threatened, uncomfortable, and avoid it from afar, and avoid the damage caused by their occupancy.

Similarly, in this house, there is a unique energy field of the Rat God Society, which makes other small creatures dare not approach, including alien beasts.

This further confirmed Zhang Qingyang's conjecture that the forces of the Rat God Society would definitely still be active in the near future.

As for the second discovery......

He crouched down, took advantage of the light through the crack in the door, walked to an open space in the room, and pursed his lips to blow a strong wind to the ground, sweeping away the dust on the ground, revealing a few shallow footprints.

The person who left the footprints had tried his best to reduce the force and cleaned it up, but he still did not escape Zhang Qingyang's observation.

"Sure enough......"

The corners of Zhang Qingyang's mouth curled slightly, his heart was determined, he got up immediately, put the iron door back in place with his backhand, and at the same time that the light in the room dimmed, a faint green light flashed in his eyes, maintaining a clear visual effect, and following the footprints to the inner layer.

At the same time, at the mouth of the alley outside, the stalker who noticed the anomaly flashed and appeared, and when he saw that the alley was empty, he was about to turn away.

Rattle......

Suddenly a hoarse cry made him stop and look back, frowning as he stared at the crow hovering in the air, a cold smile suddenly appeared on his face, and he hurried back.

A few minutes later, seven or eight more people came to the vicinity, scattered into the perimeter of the house, and went into hiding.

Zhang Qingyang didn't know this, and he followed the footprints through the two-story portal in a row to the main hall in the back row.

The structure of the houses built during the war years is relatively special, with a fully enclosed building with hard stone as the main body, and between the front and rear multiple portals, there are well-designed blocking positions, and once it encounters a sandworm attack, it can be defended by layers of terrain.

The real active zone is the innermost large cavity, which is either a semi-buried subsidence structure, or simply penetrates deep into the thick mountain, and there are portals and tunnels to other places.

The main hall that Zhang Qingyang entered had four portals in different directions, all of which looked the same on the surface, but he judged from the very inconspicuous traces that the portal in front of him on the right was the direction he was looking for.

He pointed the fingertip of his right claw on the surface of the iron door, manipulated the qi and blood to penetrate inside, and soon sketched the overall structure by perception, and then took out the rat bone sword to adjust the size, stabbed it into the keyhole and twisted it hard, attaching the "master key" that automatically filled the qi and blood, successfully opened the lock, and pushed it in with all his strength, and the door opened.

Another disgusting and strange air flow rushed out, and there was a faint shrill strange sound in it, which sounded impulsive and impetuous, and all kinds of illusions appeared in my mind.

In Zhang Qingyang's inner universe, the frog Zen master pinched the fearless seal, sang Zen in his mouth, and the clear sound naturally cleansed away all abnormalities, making his mind extremely clear, and he was not affected by the treacherous spiritual attack.

Then, he entered sideways, revealing a downward-sloping staircase.

Flicked his fingers and sent out a strong qi, and the air flow poured into all directions along the channel, and it didn't take long for Zhang Qingyang to quickly know the situation ahead with the echo of the air flow.

After six turns of the staircase, it enters a wide parallel road, judging from the direction, leading to the distant mountain, but the middle is not unobstructed, and there are some obstacles.

After knowing the specific terrain, Zhang Qingyang ran the footwork of the dragon swimming in the four seas, and quietly fell to the end, and in the dark silence, there was a faint sound of water dripping.

Zhang Qingyang raised his eyes to look at the end of his line of sight, there were different degrees of collapse at both ends of the corridor, against the air flow and the smell of rats, and the staggered tree roots could be faintly seen penetrating the top.

It's deep enough.

Zhang Qingyang didn't think it was strange, the rat god would be able to be active in the imperial capital for so many years, and its lair must be hidden enough, otherwise it would be difficult to detect.

Hundreds of years ago, in order to fight sandworms, humans built extremely complex three-dimensional fortifications between the mountains.

Especially underground, multiple corridors extend in all directions to connect the surface buildings, and a larger cave base is communicated to the depths.

As the human counteroffensive reversed, in the imperial capital, which was the rear of the country, such fortifications gradually fell into disuse, some were destroyed in battle, some became sewer drains, and some were deliberately opened up and used to become excellent channels for illegal hookups.

Therefore, it is useless to rely only on the original official drawings, and the Arrest Bureau has no interest in entangling with criminals in the labyrinth of underground fortifications.

Zhang Qingyang unfolded the bridge of the heart, and after perceiving it from afar, he walked towards the place where the roots of the tree were rooted, and when he got closer, he found that the shape of the tree roots was very strange, and the dense roots of hundreds and ten wrists were twisted, forming a curved round table in the middle.

The smell of air and rats came from the hollow.

There is a relatively fresh human breath among them, which means that someone has passed here not long ago.

Zhang Qingyang judged that this tree root was definitely not an ordinary plant, but some kind of powerful alien creature.

Do you want to go in?
