Hearing Sun Muchen say this, Wang Lan looked at the rhombus more carefully and found that the lines at the top of the rhombus were straight, but the lines at the bottom were curved and the bottom was not connected, making it look just like an arrowhead.

Wang Lan said, "It seems the owner of this basement has a particular fondness for weapons like bows and arrows!"

Wang Lan nodded and said, "I seem to have read about this in a book. Before the anomaly, many cities had so-called 'guardians' who protected the city's safety. These people were very powerful, and it was because of them that the city was able to be safe and develop steadily."

"Guardians?" Wang Lan scoffed at the name, turned and left, saying as he walked, "If those so-called 'Guardians' were really powerful, so many cities wouldn't have been wiped out in the anomaly. The Guardians could have united, but what happened? Tsk tsk tsk, the grass on their graves has grown into big trees. What kind of strength could they possibly have?"

“You can’t say that,” Sun Muchen also turned and walked away, replying, “After all, the change came very suddenly, and it may have caught them off guard.”

Wang Lan shook his head. "I don't think so. Don't forget, every danger we've encountered along the way has appeared suddenly. If we don't even have this basic ability to react, what are we talking about in terms of guarding?"

Sun Muchen listened and thought about it again and again. Suddenly, he felt that Wang Lan's words were not without reason. Especially when the mutation first appeared, the evolution of creatures must not have been as stable as it is now, so their strength must not have been as it is now.

If the so-called "Guardians" are truly powerful, then why didn't they eliminate the effects of the initial mutation in time?

Wang Lan walked back to the cylindrical glass container, looked at the constantly vibrating light spot inside, and said, "Every era has its advantages, but also its disadvantages. Although the technology of the world before the mutation was advanced, weapons relied heavily on external objects such as guns and cannons. This would cause people to neglect their own physical fitness. It is natural to be prepared at a certain safe distance, but once that safe distance is breached, one can only wait to die."

Sun Muchen nodded.

He felt that Wang Lan's analysis was very accurate.

But seeing that Wang Lan kept staring at the glass container, and wondering what was so mysterious about it, she went over to take a look.

Then suddenly exclaimed in surprise, "Ah! The energy of this light is so powerful!"

Wang Lan asked, "How powerful?"

Sun Muchen said, "This energy instantly reminded me of the reactor in the final fortress, but it seems that this energy is gradually dissipating. I can feel its energy decreasing, but this energy is just too huge. Even if it keeps decreasing, it will take a very long time."

Sun Muchen stared at the container for a long time, and finally sighed, "Speaking of technology, the predecessors are indeed more powerful. The energy of this light spot is comparable to the reactor of the Final Fortress, but it is much more stable than that reactor, and it does not require a large number of units to control it. Just based on this point alone, it is much more advanced than the technology of the Final Fortress!"

Wang Lan shrugged and said, "It's a pity that these technologies can help people live better lives, but they can't help them survive."

After Wang Lan finished speaking, she seemed to lose interest in the light spot and turned to leave.

Only then did he take a closer look at the basement.

As far as the eye could see, apart from the glittering light inside the glass container, the rest of the place was a gray, dilapidated mess, with all sorts of skeletons lying haphazardly on the ground, some recognizable as human, and others as animal remains.

But the animal ones are obviously much larger.

It seems a major battle once took place here.

Wang Lan paced back and forth in the basement and discovered that its overall structure was actually quite similar to that of the laboratory in the final fortress.

On a long table, a rotten and broken computer lay on it. After the mutation occurred, the bacteria also evolved significantly. Wang Lan flicked it lightly with his hand, and the computer immediately shattered into a pile of fragments.

On the other side was a test bench, on which various glass bottles and jars were placed in a disorderly manner, but it seemed that precisely because they were glass products, there was no sign of them rotting.

Wang Lan picked up a glass bottle and looked at it. There were several letters and symbols marked on it, which looked mysterious. Wang Lan couldn't figure it out, but the bottle was empty and there was nothing worth studying, so Wang Lan put it back on the table.

However, the moment the glass bottle hit the table, the table shattered with a crash, and all the bottles and jars fell to the ground and smashed to pieces.

The already thick layer of dust was agitated by this, and dust immediately flew up.

Wang Lan coughed repeatedly, waving her hands and patting the dust as she walked, but this only made the dust stir up even more.

Upon seeing this, Sun Muchen quickly flicked out several beams of blue light to suppress the dust.

She walked over and said, "Brother, what's wrong?"

Wang Lan quickly explained to him.

As Sun Muchen listened, she glanced at the pile of shards on the ground. Suddenly, she noticed a notebook. With a wave of her hand, a blue light enveloped the notebook, and it flew into her hand.

Upon opening it, he found that the contents were heavily stained with blood, and the paper was extremely fragile, easily crushed with the slightest force. Sun Muchen flipped through the notebook, but could only make out a few fragments of words.

"An unexpected change..."

"Bin... completely fallen... Heshe... wiped out..."

"Morinoshita City... even more serious... species outbreak... reinforcements... exterminate..."

"Regarding the strange mutation... I've created a video... which you can scan to show future generations..."

“It won’t do!” Sun Muchen closed the notebook and said, “This notebook is too contaminated. It’s a thick book, but there are very few words that can be read.”

Wang Lan recalled Sun Muchen's translation and slowly said, "It seems that this notebook is similar to the log in the fortress, both containing records of the anomalies."

Sun Muchen tossed the notebook aside, rubbed his temples, and said, "It seems that these guardians did resist when the anomaly occurred, but... it's not hard to tell from these few words that they failed, and Senzhou City, where we are, seems to be more severely affected by the anomaly."

Wang Lan thought for a moment and said, "Senzhou City is named for its abundant forests, which means there are more insects and animals. However, based on our experience, if it's only this much, it shouldn't be enough to make us unable to resist them."

Sun Muchen shook his head, indicating he didn't know, and then said, "But what intrigues me is the last sentence..."

"Scan the QR code for future generations to see?" Sun Muchen looked bewildered... "What does 'scan the QR code' mean?"
