Half an hour later, Lin Fang stepped into the core area of the secret realm.

Lin Fang carefully hid his figure, and then slowly approached a clearing in the jungle, the clearing was very large, and there was a huge Bodhi tree in the middle, under the Bodhi tree, a flaming lion covered in scars was lying on the ground, carefully licking the wounds on his body.

Although the Bodhi Fruit was stolen and the Flame Lion was very angry, it did not give up here, because the Bodhi Tree is still there, as long as the Bodhi Tree is there, it will continue to grow the Bodhi Fruit, so the Flame Lion is still quietly guarding the Bodhi Tree, and then quietly waiting for the next batch of Bodhi Fruit to ripen.

Lying in the grass, Lin Fang glanced at it from a distance, and then quietly bypassed this large clearing and continued to move forward.

Along the way, Lin Fang passed through many areas occupied by various mutated beasts, and also found all kinds of very precious treasures, including cultivation resources, healing elixirs, treasures to increase innate qi, and even treasures to increase the power of innate bloodlines.

However, each treasure is guarded by a variety of mutated beasts, such as a mutated two-headed giant wolf, a land chocobo turtle like a hill, a fiery red giant snake, and a mutated cheetah that is as fast as lightning.

Among them, there are innate fifth-order mutant beasts, and there are also innate sixth-order mutant beasts, most of which are no longer much of a threat to the current Lin Fang, but a few innate sixth-order mutant beasts can still make Lin Fang faintly feel deadly danger.

For example, the fiery red giant snake that was as thick as a man, and the cheetah that was as fast as lightning, Lin Fang felt a faintly terrifying sense of threat from them, which was stronger than the sense of threat that the Flame Lion brought to Lin Fang, I am afraid that these two should also be the very powerful ones among the innate sixth-order mutant beasts.

And the treasures guarded by the fiery red giant snake and the lightning leopard were also the most valuable treasures Lin Fang had ever seen, and even exceeded the value of the four Bodhi fruits.

In normal times, although he faintly felt that the fiery red giant snake and the lightning leopard would be very tricky, Lin Fang would still try it to see if there was any way to obtain those treasures, after all, even if he didn't use it himself, it would be a lot of income to take it out and sell it.

But at this moment, all Lin Fang's expectations were placed on the possible existence of the master's laboratory, a person who could evaluate the middle-level five-grade secret realm as "not of high grade", the value of his laboratory was far from being comparable to these treasures, and even, whether the entire secret realm could be compared with the possible laboratory was unknown.

Moreover, the appearance of the man in the black trench coat made Lin Xin faintly feel a sense of vigilance, since the first man in the black trench coat can appear, then there may be a second, third, or even countless ones.

This time, he was able to get away with killing the top innate sixth-order powerhouse who was seriously injured, but next time he might not have this good luck.

Therefore, now Lin Fang has to seize all the time to find the biggest treasure that may exist in this secret realm, a certain laboratory. In order to gain time, the other treasures, even if Lin Fang looked at it, he was very hot, but he still forcibly gave up.

If you still have time after finding the lab, it's not too late to search for it.

Lin Fang, who was so intended, reluctantly gave up all the treasures he found, hid his body as much as possible, and explored little by little in the core area.

After such a slow exploration, after a day and a night, the next day, Lin Fang had explored more than half of the core area, but still did not find anything suspicious.

There are no traces of human existence, no necessary buildings, nothing.

Sitting in the hidden treetops, Lin Fang pondered carefully while eating.

Is everything written on that piece of paper false?

But it's not right, the paper that can be so carefully preserved by the man in the black trench coat must have its value, there is no reason to be fake, at least the man in the black trench coat should have a certain degree of certainty to ensure its authenticity.

Lin Fang's gaze looked into the distance, and there was still nearly a third of the core area that had not been walked, maybe the laboratory was over there.

Lin Fang thought so, then swallowed the food in his hand in one gulp, and continued to move forward, hiding his figure, and kept clicking on the treetops.

An hour later, when he was jumping from one treetop to another, Lin Fang in mid-air suddenly moved the tips of his ears, and then the whole person's body stopped on the treetops in an instant, and the whole body was motionless, just listening quietly with his ears, and when he got to the back, he even closed his eyes and only sensed the surroundings with his ears.

"The sound of metal colliding." After more than a minute, Lin Fang opened his eyes fiercely.

Metal is a trace of human civilization, and it will definitely not be emitted by mutated beasts. And as far as Lin Fang knows, for the time being, there should be no second person in this secret realm except him.

Lin Fang's eyes lit up suddenly, and then he instantly ran in the direction where the sound of metal collision came.

...... five minutes later.

Lin Fang was hiding in the treetops, and a pair of eyes stared through the leaves, staring deadly ahead.

A wooden house, a fence, a stone platform, a small pool, in a small pool, a metal resembling a bamboo dust, constantly scooping up the water from the pool, and then pouring it into a metal plate.

The sound of metal clashing is coming from these two objects.

Lin Fang lay dead in the treetops, motionless, just staring with a pair of eyes.

It wasn't until five or six minutes later that Lin Fang jumped off the treetops, and then a pair of eyes kept shooting left and right, slowly approaching the small courtyard with a vigilant face.

When he walked to the door of the courtyard, Lin Fang's hand gently swept over the fence outside the courtyard, and the ash was thick.

Sure enough, it looks like no one has lived in it for a long time.

However, Lin Fang was still very cautious, and slowly pushed open the gate of the courtyard and walked in, he carefully inspected every corner of the courtyard, every subtle place, it seemed that the dust in each place was a finger thick.

Lin Fang looked at the footprints under his feet, the places he had stepped on, and the footprints left one by one.

In the entire courtyard, there is a strong smell of time decay.

It seems that no one has been here for at least ten years, otherwise it wouldn't be like this.

Lin Fang secretly estimated for a while, and then finally walked to the wooden house.

The wooden house was closed, and the scene inside could not be seen from the outside, but Lin Fang's eyes were full of doubt.

Is this what a laboratory is called?

Not to mention how tall the laboratory is, but it's too simple.

Lin Fang's eyes flickered, and then he walked carefully to the front of the wooden house, and gently pushed his right hand against the wooden door, and clicked lightly twice, and then a piece of dust was raised, and the wooden door was slowly pushed open.

Lin Fang stood at the door with a vigilant face, his muscles were tense, as long as there was an abnormality, he could immediately retreat.

However, when the wooden doors were all opened, it was still quiet, and Lin Fang's heart was relieved, and then his eyes swept over all the scenes in the house.

A wooden table, benches, cupboards, stoves, wooden rattan beds, small bookshelves, and then ......, and then there was no more.

The whole wooden house does not seem to have anything to do with the word laboratory at all, but it is more like the hermit wooden houses that Lin encountered on the earth.

Isn't the lab here?

Lin Fang's eyes flashed, and then he carefully stepped into the wooden house, just like the outside, the entire wooden house was still full of dust, and the ground, table, and bed, all places were covered by dust.

After confirming that there was no danger, Lin Fang carefully checked all the places, hoping to find some useful things or information, especially on the bookshelves, which was the top priority of Lin Fang's inspection.

However, after more than ten minutes, Lin Fang frowned slightly and returned to the door of the wooden house, there was no clue, except for some daily necessities, there was nothing else in the entire wooden house, and the books on the shelves were just some very ordinary books that could be bought outside.

The whole wooden house can not find any other important point except to prove that people have lived here.

Lin Fang frowned, and then strode out of the wooden house, his figure jumped up to the treetops in an instant, and the whole person took the wooden house as the center, and searched the surrounding area within a kilometer again, but still did not find any clues.

In the end, Lin Fang returned to the location of the wooden house, and in the wooden house, Lin Fang's eyes looked at every corner of the room.

There must be something else I didn't notice.

Lin Fang frowned and pondered while walking back and forth, and suddenly, Lin Fang's whole body was stunned, and his body instantly stopped motionless next to the wooden table. Lin Fang lowered his head slightly, his eyes stared at his feet, and then Lin Fang raised his right foot and stomped lightly on the ground, his voice was deep.

Then Lin Fang took a step back and stomped again, his voice dull.

Lin Fang's eyes lit up, and then he squatted down gently, carefully swept away the thick dust on the ground with both hands, revealing the thick stone bricks under the dust, Lin Fang gently knocked on the stone bricks with his right hand, and the dull voice became clearer.

Hollow.

Lin Fang raised the corners of his mouth, then grabbed the stone bricks on the ground with both hands, and gently used his innate qi to pull out the stone bricks.

However, just as the stone bricks were pulled up, suddenly there was a clicking sound from Lin Fang's feet.

Lin Fang's face changed, and then his figure jumped back in an instant, and in the blink of an eye, he retreated to the door of the wooden house, where he could attack and retreat, no matter what happened, Lin Fang could adapt to the situation.

I saw that after Lin Fang retreated to the door of the wooden house, a pair of eyes stared at the stone bricks that he gently pulled out, only to hear the sound of clicking, and then a sudden "ding", and then the wooden table in the middle of the wooden house suddenly began to move slowly.

I saw that the wooden table was slightly convex a few centimeters from the stone bricks under the wooden table, and then began to move horizontally, and half a minute later, a huge black hole appeared under the original wooden table.

The hole was pitch black, and nothing could be seen clearly, and the weird clicking sound still didn't stop, and then half a minute later, Lin Fang watched in amazement as a metal elevator slowly emerged from the black hole, and then the metal door slowly opened.

Lift?
