After hearing this, Lin Yu instantly became energetic, and quickly rushed to the window where Kui Mulang was. He listened out the window and immediately heard several very weak sounds, like metal hitting the wall.
The sound should be from a climbing device such as an anchor hook.
However, this sound sounded very far away and very small, as if it was at the lowest levels.
If it weren't for Kuimu Lang sleeping with his head leaning against the wall, sound transmission from solid objects would be obvious, and I'm afraid it would be difficult to detect.
"Listening to the sound, they are probably climbing up from outside the building!"
Kuimulang said in a deep voice.
It seems that this group of people could not find a way to go upstairs, so they chose to use climbing devices such as anchor hooks to climb from the outside of the stairs.
"Wake up Yanzi and Yunzhou and prepare to fight!"
Lin Yu whispered, still listening carefully to the movements downstairs, but through these weak sounds, he could not tell how many people there were on the other side.
Kui Mulang immediately rushed to Yanzi and Yunzhou and slapped them awake.
Yanzi and Yunzhou woke up immediately, jumped up, exchanged a few words with Kuimulang in a low voice, and immediately entered a fighting state, rushing to both sides of the stairway and elevator respectively, ready to fight the enemy.
Although the entire floor was pitch dark at this time, and they could barely see each other's figures, during the day they had memorized the layout of the entire floor by heart, so their actions at this time were not affected at all.
Lin Yu and Kui Mulang, one of them stood in front of the window, and the other moved behind a pillar in the center of the hall. They both tensed their muscles and were ready for battle.
Not long after, they heard a very faint sound of footsteps coming from downstairs. It was obvious that the other person was trying his best to control the noise he made when walking, but he could not achieve 100% silence.
Lin Yu and others closed their eyes tightly and listened carefully to the faint footsteps. He and Kui Mulang and others stopped communicating with each other to prevent their positions from being exposed.
However, with the tacit understanding and combat experience between them, there is no need for any communication. They all know what to do and how to cooperate.
Bang!
At this moment, there was a loud explosion downstairs.
This sudden sound startled Lin Yu, Yanzi and Yunzhou to tremble.
But Kui Mulang was overjoyed and full of sense of accomplishment. He wanted to tell Lin Yu and the others loudly that the grenade trap he installed worked.
However, after the loud noise, there was no movement downstairs, and the previous footsteps did not sound again. The group of people seemed to have disappeared in an instant.
Or, they might be wiped out by Kui Mulang's grenade!
Although this possibility is slim.
Lin Yu and the others waited patiently for more than ten minutes. Suddenly there was another slight noise at the top of the stairs, but it quickly disappeared.
Lin Yu and others looked stern, and instantly became alert. A cold murderous intent suddenly emerged from their eyes. They knew that the enemy had reached the floor below them.
However, in order not to be discovered, this group of people deliberately slowed down their footsteps and advancing speed, and controlled not to make any noise.
But they ignored one thing. They could control their footsteps, but they couldn't control their breathing.
When the first few people reached the stairway, Yanzi, who was guarding the stairway, immediately noticed his subtle breathing. At the same time, Yanzi flicked his wrist, and the black silk in his sleeves shot out like lightning, with a "squeak" sound.
Accurately curling up the neck of the unlucky guy at the front.
Immediately afterwards, Yanzi tugged and retracted the black silk in his hand, and the unlucky guy was immediately thrown into the floor by the black silk, and fell heavily onto a cement pillar nearby, making a muffled "bang" sound.
There was an instant commotion at the entrance of the stairs, and at the same time a loud voice was heard shouting something, as if some tactics were being planned.
"Sect Master, what did they say?!"
Kui Mulang asked Lin Yu anxiously. None of them could understand English, so they wanted Lin Yu to help translate in order to deal with the next attack.
However, Lin Yu couldn't help but feel his heart skip a beat, and said anxiously, "Their language... I can't understand it!"
What these people spoke was not English or Japanese at all, but an extremely niche language that even Lin Yu had never heard of, so there was no way to know who these people were and what kind of attack they were going to launch!
