was ridiculed by Lin Cheng, Fang Jun could only pout helplessly, after all, his actions just now were indeed a bit embarrassing, so he could only scratch his head while following Lin Cheng through the hole and continuing to walk deeper.

Although he had been to this underground headquarters before, Lin Cheng had not been to many places, especially after passing through the iron gate just now, the area in front of him was completely unfamiliar to him, he could only follow the guidance of the map and slowly approach the research room, even so, because of the light, he still walked wrong several times, and finally came to the door of the headquarters research room.

"Torah—"

Tearing off the seal on the door, Lin Cheng stretched out his right hand and tried to push the iron door in front of him, and found that he couldn't push it open, so he could only pull out the Soul Breaking Sword again, and stabbed lightly at the position of the door lock, just listen to the "click", and the door lock was pierced by him in an instant!

"You just stay at the door and don't come in, and we'll leave if I find something."

Whispered a few words to Fang Jun, and without waiting for him to reply, Lin Cheng walked directly into the research room, swept up and down a few times with a flashlight, and after making sure that there was no danger, he walked to the cabinet full of medicine bottles by the wall and quickly rummaged through.

Twenty minutes later, Lin Cheng, who had turned the entire room upside down, sat on the broken chair in the middle of the research room with a frown, carefully thinking about what he had missed just now.

After carefully rummaging through the information he had just done, he had placed all the potions he could find in the research room on the table, but the problem was that the labels on the bottles clearly told him that none of them were what he wanted!

"That's right—"

Looking at the table full of colorful bottles and cans, Lin Cheng suddenly realized that C301 had been listed as a banned drug by the headquarters a long time ago, and except for Xie Xinbai himself, the only people who could know about the existence of C301 medicine should be the senior researchers who originally worked here and those who poisoned him!

"What a stupidity!"

Finding that he was completely wrong, Lin Cheng couldn't help but curse secretly, stood up and prepared to go upstairs to find Fang Hong's dignitaries!

"Jingle Bell ......"

But just when Lin Cheng just stood up and was about to call Fang Jun to leave, a sound of bottles and cans suddenly came from behind him, and when he heard this sound, Lin Cheng's heart moved, and his footsteps stopped.

Standing in place and waiting for a few seconds, finding that there was no sound coming from behind him, Lin Cheng frowned slightly, his body quickly turned back, and the Soul Breaking Sword in his hand was also drawn out at the same time!

"This ......"

Looking at the experimental bench that still had no changes, Lin Cheng couldn't help but feel a little puzzled, although his voice just now was extremely low, he definitely didn't think that he was hallucinating!

"What's wrong, Brother Ring?"

At this time, Fang Jun, who was standing at the door and watching the wind, also noticed that Lin Cheng's behavior was a little strange, and couldn't help but ask him out loud.

"A little thing, you just watch the door, don't worry about the rest!"

Waving his hand without looking back, Lin Cheng pricked up his ears and listened carefully to the movements around him, while his eyes were firmly fixed on the experimental table not far ahead, deciding that if there was any more trouble, he would take the other party down immediately!

But a few minutes passed, and the potion bottles and cans on the laboratory table were still there, and the previous sound never sounded again.

But even so, Lin Cheng still did not relax his vigilance, more than half a year of fighting in the last days made him already understand a truth, in this troubled world, if anything goes wrong, even if it is inconspicuous, the hidden danger is enough to kill people!

"Zizi ......"

At this moment, the flashlight in Lin Cheng's hand unfortunately ran out of power, and seeing this, Lin Cheng directly threw away the flashlight that he didn't look very at, and took out a brand-new military flashlight from the storage capsule again!

Under the strong light of the military flashlight, all the items on the experimental table in front of him were clearly displayed under Lin Cheng's eyes, and he didn't hear any sound anymore, Lin Cheng could only slowly approach the experimental table with the flashlight, and after walking to the front, he pricked up his ears and listened again, but he still didn't hear any movement.

"Pretending to be a ghost!"

With a cold snort, Lin Cheng finally became a little impatient, stretched out his free left hand and groped for these bottles and cans on the table, and after finding that these bottles and cans were not abnormal, he opened the cabinet door under the experimental table and searched.

After a search, Lin Cheng, who still found nothing, was really stunned this time, he could be 200% sure that the strange noise just now came from here, but after a search, he did not find any suspicious people or objects.

"Tsk......"

Squatting next to the dark cabinet, Lin Cheng couldn't help but smack his mouth while holding a flashlight and shining it in.

After a search he had just made, he had searched inside and outside this experimental bench, but he didn't find anything suspicious, which made him feel a little puzzled.

"Huh?!"

Just when he became more and more suspicious that he was having auditory hallucinations and wanted to leave the research room and go upstairs to find Fang Hong's dignitaries, a very inconspicuous bulge above the inner wall of the laboratory cabinet caught his attention!

Squatted down again and picked up the flashlight to take a picture of the bulge, and Lin Cheng realized that the bulge was actually a hidden button!

"Good fellow, you're really making it easy for me to find!"

The moment he saw this button, Lin Cheng immediately understood that the abnormal sound he heard just now was not from this experimental table at all, but from the wall behind the experimental table!

"Click-"

After figuring out the ins and outs, Lin Cheng no longer hesitated, and directly stretched out his finger and pressed it the button, only to find that the wall behind the laboratory table did not move at all after waiting for a few seconds.

"Forgot there's a power outage here......"

After finding that the button was invalid, Lin Cheng reacted, since this mechanism was so hidden, it must need to be powered to open the secret door, so he could only shake his head helplessly, stood up and pulled out the Soul Breaking Sword.

"Whoa——!

Casually moving away the heavy experimental table blocking the wall, Lin Cheng raised the Soul Breaking Sword, aimed at the center of the wall and stabbed hard, and heard a soft sound of "poof", and the pitch-black Soul Breaking Sword blade instantly disappeared into the wall!

"Sure enough, it's a vacuum!"

Seeing that the Soul Breaking Sword easily pierced the iron wall, Lin Cheng suddenly knew in his heart, and after twisting his neck, he raised the Soul Breaking Sword and slashed at the iron wall in front of him, but after a moment's effort, this iron wall that looked quite hard was opened by Lin Cheng Shengsheng!

At the moment when the gap was opened, Lin Cheng suddenly felt a chill rushing to his face, gently waved his hand to fan the white mist in front of him, and squinted his eyes to look inward carefully through the light of the flashlight!
