The huge blue stone door finally opened after Lin Feng inserted the fourth 'key'. A passage that had not seen the light of day for a long time also welcomed the first ray of sunshine in many years.
Lin Feng and others stood in the air and hid far away, fearing that there would be some mechanism in the passage and they would be accidentally injured.
But after waiting for the giant bluestone door to open for a long time, there was no movement. Everyone was a little moved, but they didn't dare to be the first to go in.
Seeing this, Lin Feng asked You Jiu to investigate first.
As a result, You Jiu exclaimed in surprise soon after. Lin Feng couldn't help but frown after understanding.
Immediately, he entered the passage in a flash. Seeing this, the other four people followed him and fell into the passage.
But I saw that the entire passage was made of stone slabs and was quite wide, so it was easy for more than ten people to walk side by side.
Lin Feng stood at the entrance of the passage in a daze, unwilling to enter for a long time.
Behind him, the four people who came in looked at the brightly lit corridor and couldn't help but sigh.
"This slate is so smooth, it can even shine on people."
"Not only are there stone slabs under your feet, but there are also stone slabs above your head and on both sides of the aisle, all in uniform order."
"What material is the handrail made of? Why haven't I seen this kind of gold and stone?"
"The pearls at night are so bright, almost as bright as the sun in the sky, and there are so many of them!"
Xia Chichi looked at the "night pearls" arranged in a row above her head and sighed. The next moment, she was ready to dig one out and put it in her storage bag.
Seeing this, Lin Feng quickly called a halt and suggested: "Let's go deeper into the cave to see if there are any other treasures? If we accidentally trigger the mechanism, we will lose more than we gain."
As soon as these words came out, Xia Chichi quickly stopped and no longer thought about digging for the night pearl.
Lin Feng took a deep breath, what the hell is this ‘night pearl’? This is obviously a ‘spotlight’!
Yes, spotlights from technological civilization.
You Jiu exclaimed just now. It was also because of this that after Lin Feng landed in the passage for the first time, all the lights turned on. Is there a sensor switch?
Moreover, what really surprised him was how could this aisle, tiles, spotlights... feel like the earth in a previous life?
It feels like the subway station passage where he commutes to and from get off work...
"There is a puddle of water below this staircase!"
Fu Bingzhi had already walked into the passage and came to a downward step.
Lin Feng walked over and looked at the staircase, and he immediately became confused. It was exactly the same as the staircase before he traveled through time!
‘You Jiu, You Jiu!’ He couldn’t help shouting in his mind.
But for some reason, You Jiu suddenly became silent.
Lin Feng frowned, then patted his storage bag and took out a 'loach' that was as thick as a thumb and 20 centimeters long.
This is the loach robot in a safety suit, which is perfect for performing water detection tasks.
"Coach Lin, is he also proficient in the art of puppetry?" Yu Chengan asked curiously from the side.
Lin Feng ignored him and threw the robotic loach into the water to let it detect it.
He is not in any mood right now, he just wants to know what kind of existence is this 'cave'?
He couldn't contact You Jiu for a while, so he had to find a way through the safety suit.
Gulu...
The robotic loach slowly dived downwards and finally disappeared from sight.
Lin Feng took out a tactical watch from his storage bag, linked it with the robot, and projected the field of view for everyone to watch.
All I could see in the detection screen was the clear pool water, with no living creatures visible!
Lin Feng frowned and let the robot continue to detect downwards.
Suddenly, six "creatures" appeared on the screen, and everyone was shocked almost at the same time: "Dragon!"
The dragon is a mysterious creature that has existed since ancient times. According to legend, it exists in the nine heavens and the deep sea... But the dragon has never seen its tail!
Many people have only heard about it and have not seen it in person. They only make judgments based on the pictures they usually see.
Obviously, the 'creature' in the current picture is very similar to the image of a dragon.
Boom... six 'creatures' also discovered the 'loach' robot and immediately swam towards it.
When Lin Feng saw this, he quickly controlled the 'Loach' to retreat.
The six 'creatures' followed for a while, then suddenly stopped following.
There seems to be some barrier that cannot be broken through?
"It looks more like a robot!" Lin Feng frowned slightly.
"Well, it's probably a robot." Lin Feng nodded, understanding in his heart.
Lin Feng controlled the 'Loach' and continued to stay where he was, carefully observing the six 'dragons'.
All they could see were silvery-white torsos, fist-sized scales with distinct layers, crimson eyes protruding outwards, and even long beards around their mouths...
Lin Feng couldn't help but laugh. The guy who can design such a machine shape is also a talent!
The six 'dragons' had already discovered the 'loach', but they had been wandering around in a specific area and did not attack him.
It seems that there is indeed a sensor control or barrier that prevents it from acting casually.
'Look, where is the switch?'
Lin Feng's mind moved, and his mental power was immediately wrapped in a robotic dragon.
thump!
The robot dragon also felt something touching itself and couldn't help but react strongly.
Lin Feng hurriedly weakened his mental power a little more, and then the robot dragon slowly calmed down.
'Where exactly?'
Lin Feng frowned. He checked back and forth twice and found no mechanical switch - it stands to reason that all robots have mechanical switches.
Check again!
He increased his mental power and tried his best to explore.
The robot dragon suddenly began to flip wildly again, swinging around, making a lot of noise!
Lin Feng ignored it, and his mental power continued to travel rapidly throughout the body of the robot dragon...
'Well, here?'
He was overjoyed and found a clue.
It was a dragon scale, no different from other dragon scales, but there was a line connected to it inside that was one percent as thick as a human hair.
'It's really hidden, you really can't tell it unless you look carefully!'
Lin Feng sighed in admiration and used his mental power to gently turn the dragon scales.
Silk……
The robot dragon finally stopped swinging wildly and gradually became quiet, until finally the red light in its eyes completely dimmed and it floated motionless in the water.
'Fortunately, it is an old model and has a manual opening and closing device.'
Lin Feng was secretly happy and continued to mess with the second robot dragon.
This time he still chose to be simple and rude... Soon, he found extremely hidden switches on the dragon's horns, inside the dragon's whiskers, the dragon's tail fork, the bottom of the dragon's claws, etc., and then used his telekinesis to close them one by one.
Four more robot dragons floated motionless in the water.
Seeing this, the last robot dragon made a hurried splash and quickly ran towards the depths of the water!
The corner of Lin Feng's mouth raised, and he controlled the 'Loach' to follow...
I saw that the water was getting deeper and deeper, and the surrounding areas were obviously marked by human excavations, and it was getting narrower and narrower. In the end, it could barely accommodate a robot dragon hovering inside.
However, the body of the robot dragon is relatively large, and its diameter when hovering is more than three meters.
Lin Feng wrapped it with mental power and quickly disarmed it.
Then, the robot dragon slowly floated upwards. It seemed that the water pressure they were originally designed for appeared at the place where it first appeared.
The place where the robot dragon originally hovered was already at the bottom of the pool.
There are thousands of pebbles of different sizes inside, the largest is no more than the size of an egg, and the smallest is about the size of a peanut...
