Looking at the elevator that suddenly emerged from the dark hole, Lin Fang cautiously walked to the elevator after confirming that there was no danger for the time being, and then looked carefully.

The space in the elevator is not large, and it can accommodate up to three to four people at the same time, and there is only one button in the elevator, which should be the down button.

Lin Fang stood at the door of the open elevator, his eyes flashing.

Do you want to go in? Will there be any danger? Pitfall?

Lin Fang thought about it for a minute or two, then his eyes froze, he walked into the elevator quickly, pressed the down button, and then rushed out of the elevator in an instant when the door began to close.

I saw that the elevator was in Lin Fang's gaze, the gate closed, and then slowly sank into the black hole, and after that, the wooden table that had been moved horizontally also slowly began to move back to its original position.

Lin Fang stood in front of the wooden table, his ears carefully listening to the clicking sound coming from the ground, and it took nearly a minute to move before slowly disappearing.

After another three or four minutes, and there was still nothing abnormal, Lin Fang squatted down again, and then carefully pulled out the stone brick.

I saw the clicking sound start again, and then the wooden table shifted again, and a minute later, the elevator appeared in front of Lin Fang again.

Looking at the metal gate, Lin Fang pondered for a while, and then finally strode in.

There was actually a lift in a wooden house, this is definitely not normal, there must be something underneath.

It was recorded in that diary that there was very likely to be a laboratory built by a master in this secret realm, but he searched almost all the places in the core area of the secret realm, but only found the location of this one wooden house.

Then a lift suddenly appeared in the cabin, and the laboratory was likely underneath it.

A laboratory built by a senior master who can evaluate the intermediate five-grade secret realm as "not of high level" may have certain dangers, and even traps, but it is all here, and as a result, he can't enter, isn't it the same as entering Baoshan and not daring to enter, do you want to return empty-handed?

Wealth and danger are sought.

Anyway, go down and have a look.

Lin Fang walked into the elevator and pressed the down button again. I saw that the door of the elevator was slowly related, and then the sound of clicking continued, Lin Fang felt that the elevator began to sink, and at the same time, there was a strange sound from above, it should be that the wooden table returned to its original position again.

The elevator went down for nearly a minute, and then with a "ding" sound, the elevator stopped abruptly, and then, the metal gate slowly opened, and the innate Gang Qi in Lin Fang's body operated slightly.

However, when Lin Fang saw the scene outside the metal gate, Lin Fang was stunned, looking at everything outside in disbelief, and even involuntarily walked out slowly.

A huge cave thirty or forty meters high and with a radius of one or two square kilometers appeared in front of Lin Fang's eyes.

The cave is like a semi-circular cover, Lin Fang looked up at the top of the cave, there are obvious traces of artificial excavation, and every other distance is inlaid with wonderful luminous crystals, which should be similar to the existence of the night pearl, it is these luminous crystals that illuminate the entire cave range. The bottom of the cave is paved with square bricks.

The huge cave in front of me was not naturally formed, but was dug entirely by manpower.

And in the middle of the cave, a castle-like building, the palace building stands, about ten meters high, about two hundred meters wide, as for how long, in the forest from this angle is not very clear.

The palace is made of gray stone bricks, and even has wonderful patterns carved on them, and the exterior is decorated with various colors.

The main entrance of the palace is two metal gates, but to Lin Fang's surprise, the gate is open, through the gate, you can see, the front is a hall, the decoration is very simple but not lose the atmosphere. Behind the hall, there are several corridors that don't know where they connect.

Could it be that this is where the lab is? No wonder I searched the entire core area of the secret realm and disappeared, it turned out to be underground.

However, Lin Fang turned his head and looked at this huge cave with an area of one or two square kilometers, which was completely dug by hand, and such a large stroke was worthy of being able to evaluate the existence of the intermediate five-grade secret realm as "not of high grade".

Then Lin Fang's gaze gradually focused on the huge palace, a laboratory built by a powerful being that could surpass the existence of the Lord of the Underworld, and he didn't know what was inside.

Lin Fang slowly walked towards the palace, the metal door was open, Lin Fang's gaze swept over the hall, although it was in a cave, but the hall was the same as the wooden house courtyard on the ground, it was all dusty, and it looked like no one had been active for a long time.

After Lin Fang confirmed that there should be no danger, he slowly walked through the metal gate and entered the huge palace.

However, just as Lin Fang had just stepped into the palace a few steps, suddenly, there was a slight sound in the sky above Lin Fang, and then a voice that seemed to be synthesized by a computer came from above Lin Fang: "Welcome to Zhu Junneng Laboratory, please show your identification." ”

Hearing the inexplicable voice, Lin Fang first tensed up, and then after listening to all the words, Lin Fang's face obviously showed a look of joy.

Zhu Junneng? Sure enough, it was the laboratory of the man mentioned in the diary.

But when he heard that he showed his identity certificate later, Lin Fang was stunned for a moment, and he still wanted an identity certificate? What happens if I don't show it? And, isn't it closed?

But soon Lin Fang knew what would happen if he didn't show his identity.

I saw that the computer synthesized voice prompted two sentences in succession, and then suddenly, the entire palace suddenly flashed with a burst of red flashes and a strange alarm sound: "No identification, find an unknown intruder, activate the defense program." ”

Lin Fang's face changed suddenly, and then as the computer synthesized voice finished speaking, he saw several places on the ceiling of the hall suddenly open, and then several weapons similar to the True Yuan Gun were instantly aimed at Lin Fang's location. The weapon fired, and countless bullets radiated towards the forest with a strong impact.

Lin Fang's figure exploded and retreated, flashing countless bullets one after another, and then exited the palace hall in an instant.

However, what Lin Fang didn't expect was that even after he withdrew from the palace hall, on the periphery of the palace, several stone bricks were turned up, and then several identical weapons appeared instantly, the muzzles were aimed at Lin Fang, and countless bullets sprayed out.

Lin Fang's face changed slightly, and he continued to retreat, until he was thirty meters away from the palace, and the seemingly auto-sensing weapon stopped firing.

Lin Fang stared at the originally intact ground, and at this time, from the palace gate to the middle of where he was standing now, countless huge pits with a diameter of more than one meter were densely packed.

Lin Fang observed carefully for a while, and found that the weapon fired was not a true yuan bullet similar to a true yuan gun, but a physical weapon, more similar to the earth's firearms, but the power was far from being comparable to the earth's firearms, in terms of the intensity of the explosion, each of the bullets fired by these weapons was almost equivalent to the power of the earth's grenade, and even stronger only in terms of penetration.

If it is compared with the True Yuan Gun, it can even compare the power of the sixth-level True Yuan Gun, and it is enough to cause fatal danger to Lin Fang.

Lin Fang's gaze swept over the walls of the palace, and he had stopped shooting, but the muzzle of the gun was still aimed at the weapon here, and his brows were slightly furrowed.

There is also a defense system. And it looks like no one has been active for a long time, but the defenses are still running.

It's not going to be easy.

Lin Fang took a look, the six weapons outside the city wall can be rotated almost one hundred and eighty degrees, it can be said that they cover all the paths that want to enter the palace, there are no dead ends, and it seems impossible to rush in from the edge.

However, if he broke through hard, even if Lin Fang was very confident in his perception and reaction speed, with the shooting density just now, it would be very difficult to pass through this area safely.

The most important thing is that the power of this weapon is almost level 6 True Yuan Spear, and as long as it takes one shot, it is almost over.

It seems that this is the only way to go.

Birds suddenly appeared in Lin Fang's hand, and then pointed his gun at the weapons that were sticking out of the wall. Since you can't get through, it's good to destroy all those weapons.

Just listening to the sound of "chirp", a sniper rifle real yuan bullet blasted towards the weapon on the far left.

The speed of the flying bird was naturally extraordinary, and he saw that the True Yuan bullet was about to hit the leftmost weapon in an instant, but suddenly Lin Fang's face froze, and he saw that the True Yuan bullet shot by the flying bird hit a very thick metal plate.

The metal plate suddenly appeared in front of the weapon, completely blocking the bird's attack.

After successfully blocking the attack, the metal plate slowly sank, revealing the automatic weapon intact behind it.

There is also a weapon protection system, and most importantly, the reaction speed can actually keep up with the shooting of the birds.

Lin Fang frowned, with the thickness of the steel plate just now, and after being hit by a bird, although it left a trace of a hole on it, but if it wants to be completely shattered, I'm afraid it is not a matter of a few shots or a dozen shots, and there are six automatic weapons, and it is not sure whether there are other automatic weapons, it takes too long, and now what Lin Fang needs most is to hurry.

If the first man in a black trench coat will appear in this secret realm, there is a high chance that a second and a third will appear, so Lin Fang must enter this laboratory before the others appear.

I don't know what will happen with thunderous words.

The power of Thunder is far greater than that of Flying Birds, known as the king of the fourth-level sniper rifles, and if it is Thunder, it should be able to knock off the protective metal plate with one shot.

Moreover, now that Lin Fang has advanced to the fifth order of the innate rank, he does not know how many times thicker his innate qi is stronger than when he was in the fourth order, and he is no longer limited to only three shots.

Lin Fang's eyes flickered, and he quickly thought about the possibility of opening the way with thunder, but suddenly Lin Fang's face was stunned, and then he instantly raised the flying bird and shot at the automatic weapon on the far right.

With a "chirp", Asuka attacked, but a thick metal plate once again blocked the attack of the True Yuan bullet, and the automatic weapon behind it was unharmed, and then the metal plate slowly sank.

Once again, the attack had no effect, but Lin Fang's eyes flashed, and a slight smile rose at the corner of his mouth, there was a way.
