While countless players died under the claws and fangs of mutated creatures and the bullets of fellow human players, Qi Lin, who was running wildly along the secret passage, was already approaching the exit of this secret passage.

This secret passage is estimated to have been built before the battle fort, and the length is more than ten kilometers, which can not only keep retreating players away from the battlefield, but also extend the location of the exit to the wilderness area outside the abandoned city.

Qi Lin was not the first player to leave the secret passage, but at the entrance of the secret passage, there was obviously a skirmish, but there were only a few bullet casings left on the ground, but there were no corpses or bloodstains.

Qi Lin looked around, this should be on the edge of the ruins of Xuzhou City in the old era, if his feeling was correct, the secret passage happened to go all the way to the south, which also coincided with the approximate location of the underground arsenal that Isaac said.

"It's a bit of a coincidence......"

It was a vast wilderness, and to the north was an undulating hill, behind which was a deserted old city, and according to Isaac's clues, the arsenal was about ten kilometers south of Xuzhou City, and the entrance was an inconspicuous hole.

"When you say the entrance of the cave, do you mean a cave? A lot of the arsenal is a cave renovation, right? …… It must be on the other side of the hills, right? The other three directions are all flat, and even if there is a cave, it is estimated that the distance will be more than ten kilometers. Qi Lin thought for a moment, cleaned up the footprints he had left at the exit, and then walked towards the hills to the north.

However, before he walked out a hundred meters, Qi Lin suddenly turned back stiffly, looking at the secret passage exit he had drilled out, the corners of his mouth twitched unnaturally.

"Cave Entrance...... Hole...... Could it be this secret passage? ”

It is about 50 kilometers away from the city, the entrance of the cave, and it is inconspicuous...... This secret passage is almost all in line with Isaac's description, and, most importantly, this secret passage that is more than ten kilometers long is obviously not dug by the players, otherwise the amount of work is too large, almost as big as the two giant battle castles on the ground.

In other words, this secret passage is something left over from the old era......

Then, the fork in the road where the insect master was before is likely to be the passage to that underground arsenal!

"it!" Qi Lin couldn't help but burst out with a foul language, he was already very unhappy that he hadn't been able to kill that insect master, who knew that he was put on the other party again!

It's just that without the gray card, what's the use of that guy staying there? Does he still have accomplices?

Looking at the secret passage he had just come out of, Qi Lin hesitated a little, should he go back the way he came? If you go back, if someone else really responds to the insect master, will you run headlong into the other party's ambush?

"No, that's not right!"

The injuries on the insect master's body were not faked at all, and his participation in the "Dragon Slaying Operation" was only a temporary decision, from the time he joined the King Blood Dragon Lizard to attack the battle fort and seal, the time before and after was less than two hours, the insect master should not know that he was also in the battle fort.

Moreover, if the insect master knew where the arsenal was, there was no need for him to block the intersection with a bunch of ammunition boxes - if it was not Qi Lin who encountered him, but other players, in case the two sides really fought, in the same state as the insect master, there was a chance that he would die with the other party.

So what's the point of him guarding that intersection?

Qi Lin once again carefully examined the previous memories, and if there were no other uncertainties, there would be only one conclusion.

The insect master didn't know about the existence of the underground arsenal at all, and he would only make this decision when he was desperate - delaying the time should be waiting for the rescue of his teammates or the ability of some recovery class in the gene to take effect, and Qi Lin, because of the reason for holding the gray card, the authorities were confused, so they would think that the secret of the arsenal had been exposed for the first time.

“…… I seem to be a little nervous......" Drawing on this conclusion, Qi Lin breathed a sigh of relief, then slapped his cheek, picked up the assault rifle, and walked into the secret passage again.

……

After walking back for about five or six kilometers, scattered player corpses began to appear in the secret passages, and more often more were the remains of mutant creatures...... When Qi Lin advanced all the way to the fork in the road, he found that this section of the secret passage had been completely blown up, and the rubble and bricks had completely sealed the place, but it was precisely because of this that the mutant creatures chasing behind him were also blocked at the other end of the collapsed secret passage.

Was this the insect master detonated?

Qi Lin was a little puzzled in his heart, but he still put down the gun, took out a folding sapper shovel from his backpack, and began to dig up the blocked secret passage.

The quality of the construction of the secret passage is very good, so the collapse caused by this explosion is not large, and the aftermath of the explosion is not affected by the further afield.

In the process of excavation, it was not that the corpses of human players and mutant creatures were dug up by Qi Lin, but until Qi Lin completely dug up the secret passage to the fork in the road, he did not see the corpses of the insect master, Bryce, Feiyan or even Eight Fingers and others.

Feiyan, Bryce and the others probably didn't have time to retreat into the secret passage, but they didn't see the corpse of the insect master...... Qi Lin has every reason to believe that this guy is definitely not dead yet.

The road leading to the battle castle was still blocked, but there was no need for Qi Lin to keep digging - who knew if there were any mutated creatures guarding that end.

Bypassing the fork in the road that had been stopped by the insect master before, Qi Lin lightened his breathing and footsteps at the same time, raised his perception to the highest, and stepped in step by step.

If there are no other hidden branches in the secret passage, then the underground arsenal should be in front of it!

Under Qi Lin's deliberate control, the length of each step he took was a standard one meter, and after advancing a total of two thousand six hundred and forty-four steps towards this fork in the road, Qi Lin finally came to the end of the secret passage.

"That's what it is...... The entrance to the arsenal! ”

At the end of the secret passage, there is a round metal airtight door, which is also covered with a thick layer of loess, which is almost mixed with the walls around the secret passage, and under this layer of loess, a national emblem of the old era of the Chinese Republic is still faintly visible.

However, Qi Lin did not rush forward, but took a hundred steps back, and after making a small trap with tripwire and grenades one hundred and fifty meters away from the airtight door, he picked up a pebble the size of a soybean from the ground and walked to a place about twenty meters in front of the airtight door - many hidden arsenals are equipped with automatic defense firepower, and in just three years, the energy responsible for driving those devices should not be exhausted, and Qi Lin didn't want to be swept into a sieve by the machine gun hidden in the secret passage when he opened the door.

The stone was flicked out by Qi Lin's fingers, hitting the airtight door with a crisp sound, and then rebounding to the ground...... After this sound echoed far away in the secret passage for more than ten seconds, there was no change at the gate of the arsenal.

"Huh? Is there no defensive fire or is the system failing? ”

Qi Lin sighed lightly, and this time, he took out an oval-shaped can from his backpack that was much larger than a stone in weight and volume, and smashed it hard towards the airtight door-
