Upon hearing that the sample was missing, Dr. Han became restless and frantically tried to open the door, but the more he tried, the less he could open it.

On the contrary, Qi Zhen was the first to get out of the car and open the trunk to check.

The sample box is empty.

After returning from the collection point, Dr. Han divided the sample into two parts, carrying one with him and placing the other in the trunk of his car.

It turns out that what Xu Ding meant by "taking something" before he left was actually the samples.

He had long considered the possibility of the two of them being in danger and the others standing idly by, so he made preparations in advance.

For the research institute, although one sample is barely enough, two samples are obviously safer.

Xu Ding is not worth saving, but he is a sample.

Without saying a word, Dr. Han hugged the last remaining sample tightly: "I must go find him, but I must protect the only sample."

Finally, apart from Dr. Han waiting in the car, everyone else followed Xu Nuo to find the person.

Dr. Zhao, an unrelated party, was simply there to watch the spectacle with the intention of finishing off the culprit.

The second supply station was unguarded, but it was larger and had more warehouses.

The trap that ensnared Xu Ding was at the entrance of one of the warehouses.

The trap is linked to the door; as soon as Xu Dinggang inserted the key and turned the lock, the trap was triggered.

The trap contained hidden mechanisms; Xu Ding fell in and disappeared without giving Xu Nuo a chance to rescue him.

With no one above to catch them, Xu Nuo didn't dare jump down directly, fearing that both of them would be trapped and die.

Only when everyone came over together, and someone was guarding upstairs, did Xu Nuo dare to risk his life.

Xu Nuo, with a rope tied around his waist, emphasized repeatedly, "My brother carries the sample box with him. If we both die down there, no one will be able to retrieve the sample box."

He'd said it so many times that everyone was tired of hearing it.

Only Qi Zhen repeatedly assured him that she would do her best to ensure his safety, so that he could rescue Xu Ding without any worries.

Xu Nuo jumped into the trap, and as soon as his feet touched the bottom, he felt a lightness under his feet, and the ground inexplicably flipped over.

Xu Nuo yanked the rope hard, and Xia Chuhe above immediately tightened it to prevent him from falling further.

Suspended in mid-air, Xu Nuo lightly touched the bottom of the trap with her toes. The ground spun around like a pancake on a skewer, revealing that the bottom of the trap, which was visible to the naked eye, was actually an illusion.

There's a shaft in the middle of the bottom, like a poorly installed manhole cover. If someone steps on it and falls into the well, the cover spins around and stays on the ground.

Xu Nuo informed Xia Chuhe of this discovery and continued the exploration.

This time, having made preparations, he successfully passed through the "manhole cover" and descended to the bottom of the second trap.

The second layer of the trap can be firmly stepped on, about three meters away from the "manhole cover".

This is the final layer of the trap, yet Xu Ding is still not inside.

Xu Nuo groped and knocked randomly everywhere, and after a while, he knocked on a place that produced a hollow sound.

He smashed open the hole with force, and inside was a tunnel, from which a faint, foul stench emanated.

An ominous premonition rose in Xu Nuo's heart. He walked further into the tunnel, occasionally tugging at the rope around his body to make sure the people above hadn't let go.

As they walked, a fresh corpse appeared in the tunnel, with a toolbox hanging on its body.

Xu Nuo felt a pang of pain in his heart and rushed forward to check on him.

The corpse's limbs were devoured, leaving sharp teeth marks at the severed limbs, and the face was not spared either.

But Xu Nuo could still recognize that this was Xu Ding.

He opened the toolbox, and the samples inside were intact.

Deeper into the tunnel, several bodies lay scattered about, in varying degrees of decomposition.

The bodies were dressed similarly, suggesting they were people who worked in the same place.

Further ahead, the tunnel was blocked by a large rock, which Xu Nuo could not push open by himself.

Xu Nuo did not insist and went back to take the toolbox off Xu Ding's body.

He picked up his toolbox, stood still, then dropped it, picked up Xu Ding, and walked out.

After taking two steps, he put the person down again.

There was no point in leaving with Xu Ding's body on your back.

He is dead.

Dying in dungeons or rule-based areas is the fate of every evolver in the wasteland.

Xu Nuo was prepared for this outcome.

He never expected that the first to reach the finish line would be his usually cautious and wise older brother.

Xu Nuo wiped away her tears and said, "I came in the same way I came out."

Once they reached the bottom of the well, Xu Nuo pulled the rope three times in succession, signaling that he would be pulled up.

The four people above worked together to pull him up.

No need to ask any more questions.

Xu Nuo's expression and the bloodstains on his body confirmed the established fact that Xu Ding had been murdered.

Dr. Zhao couldn't help but smile slightly, and took two quick steps back.

Although Qi Zhen felt a pang of pity, she still asked, "Please accept my condolences. Where are the samples?"

Xu Nuo said coldly, "I didn't see it, just throw it away."

Qi Zhen's lips trembled uncontrollably. She tore off the rope from Xu Nuo's waist, tied it around herself, and jumped into the trap without hesitation.

Following the path Xu Nuo had taken, Qi Zhen easily brought out the samples without much effort.

She didn't complain that Xu Nuo had lied, but simply said, "Going back, it's not safe for Xiao Han to be alone in the car."

"Wait a minute." Xia Chuhe looked at the warehouse on the other side of the trap. "We haven't searched this warehouse yet, have we?"

Xu Nuo remained silent.

Xia Chuhe's question was enough for Lu Dangui to understand her meaning. She took a few steps back, ran and jumped, leaped over the trap, and jumped into the warehouse to search carefully.

"Here you go!" Lu Dangui threw something out.

Xia Chuhe reached out and caught it; it was a bucket of fuel.

Xu Nuo sneered.

Qi Zhen and Dr. Zhao both breathed a sigh of relief.

Although they couldn't save Xu Ding, the fact that the group returned intact, retrieved the samples, and even brought a barrel of fuel was undoubtedly great news.

Dr. Han was alone in the car and did not encounter any danger.
