Grassroots Travel: The Star Lord of Another World

"Roar--!"

A deafening roar echoed in the small stone chamber. The huge black monster opened its bloody mouth and a foul smell came towards him. Gao Xingchen's mind raced, and he grabbed Nan Li and protected her behind him.

"Little black!"

As Gao Xingchen shouted, a black shadow flashed by, and Xiao Hei stood in front of Gao Xingchen and Nan Li like a black lightning. It bared its teeth and issued a low warning to the black monster.

The two monsters were facing each other, and the atmosphere was tense. Gao Xingchen took the opportunity to observe the surroundings and found a narrow passage in the corner of the stone chamber, which seemed to be able to accommodate one person.

"Nanli, let's go!"

Gao Xingchen whispered, pulling Nan Li towards the passage. Xiao Hei also understood, fighting and retreating, covering their retreat.

The three of them ran all the way and finally escaped from the underground stone chamber.

"Phew... Fortunately, there was no danger." Gao Xingchen breathed a sigh of relief. He looked back with lingering fear and found that the black monster did not catch up with him. Only then did he feel relieved.

"It seems that there is someone behind Sun Hao." Nan Li analyzed calmly, "Moreover, what they are looking for is definitely extraordinary."

Gao Xingchen nodded, his eyes firm: "We must investigate this matter thoroughly and not let them succeed!"

"But what should we do now? Should we go find Sun Hao directly?"

Gao Xingchen pondered for a moment and shook his head: "No, it's not the right time yet. We know nothing about their background, and any rash action will only alert them."

"Then you mean..."

"Follow them!" Gao Xingchen's eyes flashed with a gleam of light, "Since they are looking for something, we just follow them and we will find something."

Nan Li smiled slightly and appreciated Gao Xingchen's wit: "Good idea, let's do as you say."

Therefore, Gao Xingchen and Nan Li decided to continue to follow Sun Hao and others. They used Xiao Hei's sensitive sense of smell to track Sun Hao's scent all the way and finally found them in a desolate wilderness.

Sun Haozheng and the three strangers sneaked into an abandoned castle. The castle had long been dilapidated, with mottled walls and vines entangled, like a sleeping beast, exuding a gloomy and terrifying atmosphere.

"Why would they come to such a place?" Gao Xingchen frowned, his heart full of doubts.

Nan Li observed the surrounding environment and whispered, "This castle seems a little strange. Let's be careful."

Gao Xingchen nodded, signaling Xiao Hei to stay where he was and keep watch, and then he and Nan Li quietly sneaked into the castle...

The interior of the castle was even more dilapidated than the outside. The air was filled with a damp and corrupt smell, mixed with some indescribable weirdness that made people's backs cold. Gao Xingchen and Nan Li walked lightly and moved forward cautiously in the faint moonlight.

"Be careful!" Nan Li warned in a low voice, pointing her finger at the ground. Gao Xingchen followed her gaze and found some animal bones scattered on the ground, which were already rotten. It was obvious that no one had been here for a long time.

The two walked cautiously along the way, passing through the gloomy corridor, and came to a huge iron door. The iron door was rusty and carved with some strange patterns, like some kind of ancient runes, exuding an evil aura.

Gao Xingchen tried to push the iron door, but it didn't move at all. "It seems that this door is locked." He whispered.

Nan Li took out a dagger from her waist and cut the iron lock with a light stroke. She pushed the iron door open a crack and motioned Gao Xingchen to go in first.

Gao Xingchen nodded and walked sideways into the door. As soon as he entered, a cold breath hit him in the face, making him shiver. He looked around and found that this was actually a huge underground space.

In the center of the space, a huge circular platform occupied most of the area. There were many strange instruments around the platform, flashing a faint blue light. Various test tubes, beakers, and utensils were placed on the platform in a mess, and some unknown liquids were bubbling in them, emitting a pungent smell.

At the other end of the platform, there is a huge stone table with a complex star map drawn on it. The star map is marked with densely packed symbols and lines, which is dazzling.

"What is this place?" Gao Xingchen looked at the strange scene in front of him, his heart full of doubts.

"It looks like a laboratory." Nan Li walked to the platform and carefully observed the instruments. "Moreover, it is a very high-tech laboratory."

At this moment, a low voice came from below the platform. Gao Xingchen and Nan Li looked at each other, then immediately walked towards the direction of the voice with light steps.

After going around the platform, they found that there was a secret room below. There were two people wearing black cloaks guarding the entrance of the secret room. Judging from the powerful aura emanating from them, they were obviously not ordinary people.

Gao Xingchen and Nan Li looked at each other and decided to wait and see what happened and figure out what was going on.

"Can the Star Gate really be opened?" In the secret room, Sun Hao's voice was full of doubt.

"Of course you can." Another old voice sounded, with a hint of coldness, "As long as you collect all the keys to the star realm, you can open the gate to the star realm and gain supreme power!"

"But, we have found three Star Keys, and we are still missing the last one. Where should we find it?"

"The last key to the star world is in..."

The old voice stopped abruptly, as if it had realized something.

Gao Xingchen and Nan Li were shocked, knowing that they might have been discovered...

Gao Xingchen and Nan Li held their breath, not daring to make a sound. They knew that they had accidentally heard a shocking secret, and if they were not careful, they would be killed.

"Someone's here!" The old voice sounded again, this time full of vigilance and murderous intent.

The stone door of the secret room opened with a bang, and two black shadows rushed out like lightning, heading straight for Gao Xingchen and Nan Li. Gao Xingchen and Nan Li didn't have time to think about it, and turned around and ran away.

"Where to run!"

Two men in black were chasing after them, their sharp blades flashing coldly. Gao Xingchen and Nan Li were running in the intricate passages, and the roars of the men in black could be heard from behind them.

"Hurry up! I'll stop them!" Nan Li suddenly stopped and turned to face the man in black who was chasing them.

"No! It's too dangerous!" Gao Xingchen wanted to stop him, but Nan Li had already rushed forward.

"Don't worry about me! Go! Tell Immortal Wu what happened here!" Nan Li shouted, and the long sword in her hand stabbed at one of the men in black like a poisonous snake.

Gao Xingchen knew that if he stayed he would only become a burden to Nanli, so he had to grit his teeth and continue running forward.

He ran all the way and finally escaped from the castle. As soon as he left the castle, he felt the ground shaking violently. Looking back, he saw dark clouds over the castle, lightning and thunder, as if the end of the world had come.

Gao Xingchen was worried about Nan Li's safety, but he also knew that going back now would only lead to his death. He had to tell Wu Xianren about what was happening here as soon as possible and ask for help.

He summoned Xiao Hei, and the man and the wolf ran wildly under the moonlight, galloping towards the direction of the training ground.

Can Gao Xingchen and Nanli return to the animal training grounds safely and tell Wu Xianren the secrets they discovered?
