The whole railcar moved slowly, then faster and faster...... Only a loud "bang" was heard, and the rail car directly smashed through the barricade used to seal the road at the tunnel entrance, and plunged into the dark tunnel.

The railcar's console comes with a smart operating system, so as long as Qi Lin starts it, the railcar will always take him and Song Xiaodie straight to Vault 188, unless it encounters some sudden failure or Qi Lin manually operates the brakes.

Watching the rail car gallop in the darkness, Qi Lin knew that they were safe for the time being.

Completely handing over the driving operation to the intelligent system, Qi Lin walked out of the cab and walked gently to Song Xiaodie's side.

"Huh?"

Qi Lin was a little surprised to find that the wound on Song Xiaodie's abdomen was no longer oozing blood, and the originally pale little face had also regained a trace of blood, and he immediately squatted down and put his finger on the girl's pulse.

The pulse was still weak, but it was steady, not at all like a seriously injured person who was dying.

"Could it be...... Bloodline constitution? ”

Qi Lin was stunned for a moment, he suddenly remembered the potential of his body that was stimulated by the game cabin - now in the real world, some small abrasions and cuts and other wounds Qi Lin didn't have to care about it at all, it would heal on its own in ten minutes, and even scars would not be left.

And Qi Lin clearly remembered that among the blood constitutions that Song Xiaodie inherited from Isaac, it seemed that he also had the ability to speed up the recovery of injuries.

It seems that that ability should have been stimulated by Song Xiaodie, otherwise, her injuries would not have healed so quickly.

"If you have a blood constitution...... I don't know if it's useful to drink blood......" Qi Lin suddenly had a strange thought in his heart, and immediately sat down cross-legged, hugged Song Xiaodie's upper body to his lap, and then took out the dagger and slashed his wrist hard.

Yin Hong's blood immediately flowed out, and Qi Lin hurriedly put his arm to Song Xiaodie's mouth-

The blood kept flowing, but Song Xiaodie kept pursing her lips tightly, and there was no reaction.

"Sure enough, vampires or something, it's a legend after all...... Maybe it's just some kind of special ability that likes to suck blood......" Qi Lin shook his head in disappointment, until now, he was still suspicious of Isaac's identity.

After all, the phrase "perfectly in line with the real wasteland" is just one side of the mastermind, and maybe the vampire is just an easter egg.

Just as Qi Lin was about to remove his wrist, Song Xiaodie, who was in a coma, suddenly grabbed Qi Lin's wrist, opened her mouth, and gulped down the blood flowing from Qi Lin's wound.

“——！！” Qi Lin looked at the girl with her eyes closed and sucking her blood vigorously with some consternation, although this scene was really a little terrifying, but seeing that the blood on the girl's face was rapidly recovering, Qi Lin did not push her away, and let her continue to absorb blood.

After a few minutes, Qi Lin's own recovery ability gradually began to take effect, the wound on his wrist began to scab, and the blood no longer spilled, but the moment Qi Lin pulled his arm back, Song Xiaodie's eyes suddenly opened, and a pair of blood-red demonic eyes stared at Qi Lin deadly!

Then, an unimaginable force erupted from the girl's body, instantly pushing Qi Lin down on the floor of the rail car, and the whole person turned over and rode on Qi Lin's body, biting Qi Lin's neck-

"Wait——!"

Qi Lin wanted to stop Song Xiaodie, but when Song Xiaodie bit his neck, a strange feeling suddenly surged into Qi Lin's brain - pleasure, yes, a special pleasure, although there was some slight pain in the wound on the neck, but it was nothing compared to this pleasure, for a moment Qi Lin even felt that the feeling of this blood being withdrawn from him was too comfortable, if he could, he was willing to indulge in this pleasure all the time......

……

……

When Qi Lin woke up again, the rail car was still speeding through the dark tunnel, the wheels and rails were constantly making small friction sounds, and the cold wind was pouring in through the broken glass window of the cab, and in his arms, a petite and warm body was curled up, slightly undulating with the rhythm of breathing.

"Just now...... What's going on......"

Qi Lin stretched out his hand and subconsciously touched his neck, and when he touched the scabbed wound, he remembered that he had just been sucked by Song Xiaodie.

"Damn it...... What the hell is going on......"

Qi Lin glanced at Song Xiaodie, who was sleeping in his arms, the blood constitution could recover his injuries by sucking blood, Qi Lin naturally knew, but the strange power just now, as well as the pair of red and blood-colored eyes, made him a little jealous.

"This guy...... You can't really become a vampire, right? ”

There was still a trace of blood on the corner of Song Xiaodie's mouth, and Qi Lin used his fingers to open the girl's soft lips, but in the girl's mouth, there was still only a mouthful of neat and thin teeth, and there was no sharp fangs unique to vampires.

"It's really ...... to see the hell" Qi Lin would rather believe that everything just now was an illusion, but the wound on his neck was real.

"Looks like we'll have to wait until this guy wakes up and ask again." Qi Lin hugged Song Xiaodie aside and stood up from the ground, but before he could stand firmly, he felt a wave of dizziness hit him, and he couldn't lift any strength up and down his body.

"I'll ...... You guy, how much blood did you suck me......" Qi Lin knew that this was a symptom of severe anemia, and immediately pulled over the backpack that was thrown on the ground, at this time, he had to find something that could replenish qi and blood, otherwise, he would probably fall into a coma again because of anemia.

On the battlefield, it is generally used to deal with the wounded who have lost too much blood, and an emergency blood replenishment injection is generally used, and after the wounded's condition is stabilized, they are sent to the rear for blood transfusion treatment, but Qi Lin does not have that kind of emergency blood replenishment injection now, and can only rely on food to stabilize his state.

Qi Lin opened a can of beef offal, took out the liver and tripe in the can, and stuffed it into his mouth indiscriminately, then took out a bottle of sugar water and poured most of the bottle down.

After the two foods were eaten, Qi Lin felt that his dizziness was slightly relieved - fortunately, he also had a physique that recovered quickly, otherwise, if he was an ordinary person, he would have to be sucked to death by Song Xiaodie.

After sitting on the ground and resting for a while, Qi Lin stood up and returned to the cab, now Song Xiaodie's condition is even better than him, so there is no need to worry about it at all.

"You save my life, I'll give you two mouthfuls of blood, and in the end, I earned it." Qi Lin muttered quietly, and his gaze moved to the upper right corner of the console, where there was a palm-sized screen that read: 14 kilometers from Vault 188.
