Just as Lin Tian and others were worried about how to get in, Dr. Long's voice rang in the corridor, telling them directly that the key to opening the door was hidden in a room in the corridor!

After Dr. Long said a simple sentence and gave a prompt, he stopped making a sound. Li Li and others glanced around. Although they could not see any abnormalities, they also knew that everything was under the surveillance of the enemy since they entered the Emgrand Building.

"Brother Lin, do you think this guy's words are trustworthy? Is it a trap?" Li Li asked Lin Tian.

Lin Tian shook his head and said directly what Dr. Long said must be true!

The most critical key to opening the door must be here!

Lin Tian did not explain why Lin Tian was so sure, but only said that it was his intuition.

However, in the face of such a dangerous enemy, how could Lin Tian make a judgment based on his intuition? He believed that it was naturally carefully considered.

Since Lin Tian said it was credible, everyone naturally had no objection. They completely regarded Lin Tian as the backbone, so they directly began to think about the question of going deeper - where is the key?

Looking at the long corridor and the rooms on both sides, Li Li and others felt their heads hurt.

Since they are in the room, the doors of these rooms must touch the corresponding mechanism to open, which means they can only keep trying to open the doors one by one and check them one by one.

Needless to say, the key is to do this, and I think that taming the two-headed leopard in order to come early was simply unnecessary.

If I had known this, I might as well come here according to the old method. At least there are fewer rooms that need to be viewed now.

Everyone looked depressed. Unknown dangers always make people feel uncomfortable. But now that things have come to this point, it is impossible not to look for them. Not only do they have to find a way out, but they also have to find ways to meet with the large army. Although they are in the current situation, everyone knows nothing.

Li Li clapped his hands and cheered up everyone. They were about to send someone to ride a two-headed leopard to collect small stones, and then follow the old methods, start walking opposite from this end, open all the doors one after another, and try their luck.

At this moment, Lin Tian, ​​who had not made any noise after speaking, stopped everyone and said, "Don't worry, maybe we are lucky. Maybe the room with the keys hidden has been opened by us."

Lin Tian's words immediately made Li Li and others cheer up a little, so they were about to ask someone to ride the two-headed leopard to check the open doors first, but Lin Tian stopped them again.

"I think there is no need to be so troublesome. Maybe that room is near us. Why not go there first and take a look."

After Lin Tian finished speaking, he took the lead and walked to a nearby room regardless of everyone's confusion.

Everyone hurriedly followed, Lin Tian checked the floor nearby as soon as he arrived, and the nearby area near the exit gate was safe.

Lin Tianzhi walked into a room by himself. When everyone saw that this was the door that was opened unexpectedly just now. The cunning mouse monster died in the Venom Pool.

"Bang!"

Just after everyone entered the room, the door suddenly closed. Everyone was startled. The person walking at the back rushed up and pulled the door hard, but now it was locked.

"I'm right, this time, our luck is not bad."

"This place must be a room with keys hidden!"

Lin Tian was not panicked at all, and he was extremely calm and glanced at the small room.

Based on the previous situation after opening each room, he analyzed and judged that except for a few stairs with unknown locations inside, the rest of the rooms with hidden weapons or monsters were empty.

When those rooms were touched, the buried murderous intent was immediately revealed. Only this room, although it seemed to have a hidden mechanism, namely the Venom Pool, it was fine if people didn't walk in. This empty room with nothing in the house, even if it was opened, Lin Tian and others would not run in without any trouble, nor would they fall into the trap.

Unless its function is not that simple at all, it must have other uses. Now it seems that Lin Tian has guessed it right.

"Look, the venom in the venom pool is rising! Hum? There seems to be a box inside, which looks like it is being fixedly closed."

"Yes, it looks very solid. Hey, what does the hole that is so deep in this pool do?"

After everyone walked in, the venom pool appeared to be unusual. As soon as they spoke for a few words, they suddenly heard some sound and immediately glanced around, but nothing appeared.

"It's the sound of pumping air. There are hidden pipes there, and there are even a few places over there, that are pumping out oxygen at a uniformity."

Lin Tian just listened and gave the answer directly.

Everyone's faces suddenly became very ugly. The sealed room, which was not big, was locked, and the oxygen was still being pulled away.

Moreover, the venom in the strange venom pool was also slowly rising. Everyone was not only worried that the venom would continue to increase, but they knew that they would spread across the pool and kept rising until they melted them all!

The strange situation one after another, and everyone seemed panicked. Even the two-headed leopard was whistling uneasy, but Lin Tian stared at the thing fixed on the bottom cylinder in the Venom Pool, like a box, which seemed extremely calm.

"Brother Lin? Could it be that inside?"

Li Li noticed Lin Tian's calmness and gaze, felt something, and immediately asked.

"Yes, that's a sealed box. What lies there is the key." Lin Tian said lightly.

"What? It seems that it is really here, and the hidden key has been found! That's great!" someone said happily.

"What's the good thing? Look, the venom has spread across the stone box. Not to mention that it looks quite solid, it can't even be opened on the base of the pool. Even if a box is placed there, it's impossible to get it up!" someone said worriedly.

The man said it was right. The increase of the venom made the stone box that was originally just a small half soaked in the venom, and it was still rising.

Everyone was already a little excited, but suddenly they were lost again, and they all seemed even more panicked than before.

"Haha, it's very simple to open that box and get the key inside. As long as we have someone who can jump into that hole, the mechanism inside will be activated, the stone box will rise and open, and the key will naturally be obtained."

Lin Tian chuckled and everyone immediately looked at the hole in the pool carefully. If it was as Lin Tian said, then the person who jumped down to touch the mechanism would definitely die, because there was naturally a lot of venom in the hole.

Everyone's faces became even more ugly. How vicious the enemy was. This was forcing them to watch and even actively sacrifice their companions' lives in order to get life!

Everyone looked at each other, and their expressions looked so complicated. Obviously, no one wanted to sacrifice himself, but if no one sacrificed, they would die here!

"Brother Lin! I... let me do it. I'm very happy to know everyone. Although it's a short time, I really have regarded everyone as my brother."

"I am also very grateful to Brother Lin for your life-saving grace. I... let's see you again in the next life."

"Everyone remember to tell my sect and tell them all how I died, and I want them to know that I am not like they always laugh at!"

"I'm not a coward!"

The coward before actually stood up and took the initiative to make sacrifices. After saying that, he closed his eyes and jumped into the hole, but he was stopped by someone.

Several more people volunteered to sacrifice themselves, but the reason was that they were alone, everyone was good brothers, and all had family members to take care of them.

Of course, there are also people who suggest that no one should be sacrificed at all. Just throwing the two-headed leopard down should also touch the mechanism. The two-headed leopard did not roar and object, but seemed to be thinking and hesitating. Of course, it did not care about other people's lives, but Lin Tian...

"Ao!"

The two-headed leopard roared and pounced towards the hole. It wanted to use its life to win a way out and vitality for Lin Tian!

The two-headed leopard was so sudden that no one expected that it had just recognized Lin Tian as the main person and was so loyal that no one stopped it. Obviously, it was better to sacrifice it than to sacrifice the brothers around him.

But Lin Tian, ​​who was standing by the pool, quickly hugged the double-headed leopard with his waist and stopped it from castrating.

Putting the two-headed leopard on the ground, touched its head with relief, and facing everyone and a leopard's puzzled eyes, Lin Tian said:

"Look at you guys who are anxious. I just said there was a key inside, but I didn't say that it was the key to open the corridor door!"

Lin Tian's words made everyone confused, but then Lin Tian didn't explain, and directly held the Killing God Sword, and a sword energy headed towards the ceiling above the Venom Pool.

With a bang, a hole was broken and a box fell down, which seemed to be explained like the doors around the walls.

Lin Tian waved his hand and took the box in his hand with his true energy. Once he opened it, there was a key with an exquisite shape. Judging from the size, it was opposite the corridor gate.

At this time, the door of the room that was originally closed opened with a click, and everyone was surprised and happy, feeling extremely glad.

Afterwards, Lin Tiannat taught them that the enemy used the means of locking the door to raise the venom and extracting oxygen to create an urgent situation, in order to create panic and make people unable to make a calm judgment.

And this mechanism is obviously specifically targeting people like Lin Tian who have the ability to see through. Fortunately, he was unmoved at all and calmly found the real key.

Everyone immediately went out one after another and arrived at the corridor gate.

When he took the key alone, Lin Tian's ears suddenly moved, and he felt something was wrong.

He immediately raised his perspective eyes and swept to the door in front of him. He had already checked it, and it was a place that was empty, but now it was filled with things that scared him.

"Don't open the door!"
Chapter completed!
