The alien species soon caught up.

Fear swept through the hearts of the three people.

The girl in the middle pushed her two companions away first, and collapsed on the ground, her face pale with fear. "You guys run! I... I will hold it." Her voice trembled violently.

"What the hell can you drag? It's not even enough to fill my teeth! Hurry up and stand up!" The short-haired girl grabbed her arm and pulled her up desperately.

The girl in sportswear picked up a branch from the ground, protected the two of them behind her, and glared fiercely at the alien that was chasing them.

Tu Ran has already confirmed that these people are from the first world.

The alien didn't take the branch seriously and roared at them, and the airflow blew the three of them back half a step.

Then, the alien opened its huge mouth like the abyss and bit towards the three people.

"Ah——" The girl with short hair hugged the girl in white dress on the ground tightly and screamed because of extreme fear.

Perhaps the scream was too harsh, the alien was stunned for a moment.

In the moment it was stunned, Tu Ran appeared in front of it.

The laser gun turned on, and the blue beam shot directly into its mouth. Tu Ran moved his arm upwards, and its head was quickly cut in half by the laser beam, leaving it with no ability to fight back.

The alien's corpse fell to the ground with a thud, and thick green blood continued to flow out from the cut.

The forest suddenly became quiet, with only the sound of flowing blood remaining.

Tu Ran took a step back, looked at the three people standing there in a daze, and said, "Leave here, this blood is corrosive."

Hearing her reminder, the girl in sportswear reacted first. She pulled up her two companions on the ground and took more than ten steps back.

As soon as they left, green blood flowed to where they had been, making a sizzling sound.

The three of them watched this scene and then looked at Tu Ran.

There was vigilance, gratitude, inquiry, and surprise in his eyes.

Tu Ran ignored all this. She glanced at the wound on the leg of the girl in the white dress, took out a recovery potion from the space, and walked towards them.

The three of them took a step back at the same time and looked at her nervously.

Tu Ran stopped and spread her hand, revealing the injection in her palm. "Her wound needs to be treated in time. Give her this injection and she will be healed soon."

Hearing that her voice belonged to a girl, the three of them relaxed their guard against her a little.

The girl in sportswear came over and took the recovery potion from her. She was a little unconvinced and asked cautiously, "Is this really okay?"

"Okay." Tu Ran nodded.

Although the girl in sportswear still had some doubts, she could not think of any other solution now. Besides, this man saved them. If he wanted to harm them, there was no need to save them.

"Thank you." She returned to her companion, pulled out the needle of the recovery agent, and gestured on her companion's body for a few times. For a moment, she didn't know where to start.

"You can get it anywhere." Tu Ran said.

"Okay." Her hands were shaking badly, but she still easily pierced into her companion's arm and pushed the liquid in.

Both of them watched their companion's reaction nervously.

"We can't stay here for long. The corpse of the alien species will attract more alien species. You carry her on your backs and we will go to another place." Tu Ran said. When the two heard that it would attract more monsters, they didn't dare to delay. They cooperated to put the girl in the white skirt on the back of the girl in the sportswear and followed Tu Ran to leave.

Tu Ran took them to a place with fewer trees. The sunlight could penetrate and it was not so gloomy. There was also a three-meter-wide river with large and small stones on the river beach. It was a perfect place to rest.

After walking all this way, the wound on the girl in the white dress's leg healed visibly. The bleeding stopped, and new pink flesh grew out. The pain also dissipated, leaving only itching.

The three of them were stunned by such a magical scene.

"Where are you from?" Tu Ran asked, although she already knew the answer.

The three of them looked at each other, and the girl in sportswear said, "We seem to be from another world. This world is completely different from our original world."

"Can you tell me how you got here?"

"The three of us went on a picnic, and there happened to be a small stream there. It was very shallow and the water was very clear. There were tadpoles in it, so she went into the water to play," the girl in sportswear pointed at the girl with short hair, "and she fell down. The two of us rushed to pull her up, and then the three of us fell down together. When we stood up again, we were in this forest and encountered the monster."

Tu Ran guessed that the place where they fell might be a threshold.

A connection has also appeared between the first world and the third world! Tu Ran felt heavy-hearted.

"You three have not been separated from each other since you fell down and came to this place?"

"No." The girl in sportswear shook her head and looked at Tu Ran, not understanding what she meant.

When people from the second world arrive in the third world, they will be separated and sent to different places.

However, this situation does not occur when people from the first world go to the third world.

Why is this happening?

How many threshold gates are there in the First World? Have the relevant departments discovered them? If not, what if someone accidentally breaks into the Third World and comes to the Third World unarmed? Wouldn't they just wait to be eaten by the aliens?

Tu Ran’s frown deepened.

There is a more important issue.

Is there a door that connects the Federation and the First World? Compared to the connection between the Intra-Threshold World and the First World, Tu Ran is more afraid of seeing the Federation and the First World connected.

The greed of the federal tycoons and the advanced federal technology are far more difficult to deal with than the alien species.

"Who are you? Is Tu Ran your name?" The girl in sportswear did not notice Tu Ran's anxiety and asked cautiously.

In their eyes, Tu Ran was dressed in a high-tech combat uniform, holding a highly destructive laser gun that they had only seen in science fiction movies. He was also wearing a fully enclosed helmet, so his facial features could not be seen, and everything about him was unfamiliar to them.

The five words "Pioneer Tu Ran" on the front of her clothes were the only information they could get.

But they had never heard of what pioneers were.

"Where are you from? Are there humans in this world?" she asked tentatively.

Tu Ran looked at her in surprise. She had thought of this so quickly.

"My name is Tu Ran. There are no humans in this world. It is a world of alien species. You can also say it is the world of Shan Hai Jing."

Shan Hai Jing? The three of them looked at her in unison.

Although Tu Ran did not say it directly, but as soon as the words "Classic of Mountains and Seas" came out of her mouth, the three of them knew that the person in front of them came from the same world as them.

The last bit of vigilance of the three men disappeared.
