"Big brother, what did you find?"
Xiao Xiao rubbed her cheeks, which were a little red, and ran to Ye Feng's side, asking.
"Under normal circumstances, if there's a secret room behind the wall, we can hear the echo of the space behind it by tapping!"
"But if the wall is too thick and the material is special, you won't hear any echo!"
"That explosion-proof door just now, its thickness must exceed 2 meters, and its material contains lead blocks. If you knock on the outside, you'll only hear a dull thud, not an echo!"
Ye Feng explained rapidly to Xiao Xiao as he observed the wall.
"Then how can we find places where there might be secret rooms? We can't dig open all the surrounding walls!"
Immediately, Xiao Xiao asked a crucial question.
"Look at the patterns!"
"Xiao Xiao, from the structure of this underground building we've observed all the way here, if there's a secret room, it must be connected to the wall!"
"This way, the wall connected to the secret room will sink slightly due to the immense weight. These walls are carved with patterns, and if we find places where the patterns are inconsistent, we can probably locate the secret room!"
Ye Feng said as he carefully examined the patterns on the wall.
After Ye Feng's explanation, Xiao Xiao quickly ran to another wall and observed it carefully.
Silence fell in the room, broken only by their footsteps and breathing.
"Big brother, over here!"
Suddenly, Xiao Xiao's excited voice rang out.
"Hmm?"
Upon hearing this, Ye Feng quickly ran to Xiao Xiao's side.
"Big brother, look at this wall. The patterns on it should have been continuous and integrated, but here, they are slightly twisted and sunken!"
"And here... here... here... all of them..."
Finishing quickly, Xiao Xiao shone her flashlight on several spots on the wall.
"Indeed, affected by the immense weight of the structure behind it, this wall has slightly sunk!"
Seeing this, Ye Feng was also quite pleased.
Then, with a flash of light in his hand, his Tang saber instantly appeared, and he began to chop with great force.
"Clang~ clang~ clang~..."
"Bang~ bang bang~ bang..."
As a sound of metal cutting echoed, pieces of metal were thrown to the ground by Ye Feng.
The hole Ye Feng and Xiao Xiao had made in the wall grew larger and larger, and eventually, Ye Feng even entered the hole to cut.
"Bang!~"
As a large piece of metal was thrown to the ground, a gust of wind blew towards Ye Feng.
"There really is a space behind this!"
Although Ye Feng's vision was still dark and without light, he was sure there was a relatively large space ahead.
"Clang clang~!"
After more cutting, Ye Feng shone his flashlight forward and immediately discovered a secret room behind. Although not large, it had many cabinets for storing documents, and some papers were scattered on the floor.
Ye Feng entered first, observed for a while, found a switch, and pressed it.
"Click~"
The previously dark room was instantly illuminated.
"This room... even the lighting circuit is independent..."
Looking at a large battery pack in the corner, Ye Feng muttered to himself, then called out to the hole he had dug, "Xiao Xiao, you can come in, there's no danger here!"
"Okay~!"
Hearing this, Xiao Xiao immediately picked up her Voltorb and quickly walked towards Ye Feng.
Ye Feng then quickly began to examine the documents in the room.
Given his previous experiences, he was very curious. This military base called Red Shore Ruins was too strange. The "gym" with the small giants... the nuclear power plant where the core exploded but there was no radiation... the chlorine pool with many strange black insects...
...
Half an hour later,
"Specimen No. 192 died after irradiation with the divine stone, experiment failed..."
"Specimens No. 212 and 213, twins, died after irradiation with the divine stone, experiment failed..."
"Specimen No. 456, a Silver-tier arcane energy cultivator, died after irradiation with the divine stone, experiment failed..."
...
"...Chlorine pool experiment failed, Specimen No. 8, the energy-devouring black worm king, died after irradiation with the divine stone, experiment failed..."
...
"What are all these things..."
Flipping through the thick stack of failed experiment records in his hand, Ye Feng was puzzled.
When he reached the end, Ye Feng's eyes suddenly lit up.
"Specimen No. 17, a fifth-tier zombie, survived after irradiation with the divine stone, experiment successful... Specimen No. 17 evolved from a high-tier fifth-tier zombie to a sixth-tier zombie and became extremely brutal... Alpha squad and Sigma squad were annihilated..."
"The extremely powerful abilities of Specimen No. 17 almost destroyed half of the base. Commander Joseph discovered Specimen No. 17's weakness and trapped it near the base's energy center, close to the nuclear reactor's nuclear waste... using nuclear radiation to suppress Specimen No. 17's power..."
"...Specimen No. 17 underwent unknown mutations... it showed dependence on nuclear radiation, even consuming nuclear waste... Specimen No. 17 became frenzied and began to attack the nuclear reactor..."
Seeing this, Ye Feng, who was full of doubts, had to stop, as the latter half of the document had been torn off.
"Someone tore off a part of this document in a hurry when leaving here?!"
Looking at the research documents scattered on the ground, and several cabinets that had been almost violently pulled open and not closed, Ye Feng began to understand.
He then continued to examine the documents in the room.
...
Time ticked by,
As Ye Feng felt his body growing tired and his eyes dry, he finally had a good grasp of what the Red Shore Ruins was all about.
Just as he had heard before, the Red Shore Ruins was indeed a military research base, but its content was more than just the 강화 혈청 (enhancement serum) that was rumored outside.
From the documents Ye Feng had obtained, the true research subject of this military base was likely the divine stone.
All experimental subjects, regardless of what enhancement serums they had injected or what abilities they had gained, would eventually be captured for what was called divine stone irradiation...
"Divine stone!"
With a flash of light in his hand, Ye Feng produced a square, black box with mysterious patterns on its surface. It was the divine stone he had obtained in Desperate City.
"Divine stone irradiation... this strange divine stone isn't glowing either..."
Muttering, Ye Feng put the divine stone back into his spatial storage.
He had studied this divine stone multiple times along the way, but besides its peculiar material and the mysterious runes on its surface, he couldn't find anything special about it.
"Divine stone... again the divine stone..."
Ye Feng frowned slightly. The documents he obtained from Desperate City indicated that the Desperate Potion was also successfully produced after irradiation with the divine stone.
Furthermore, the document mentioned, "All biological entities directly irradiated by the divine stone died..."
"Big brother, look, what did I find?"
At this moment, Xiao Xiao ran to Ye Feng's side, looking very cheerful and happy.
