The data chain on Dongxiang's bracelet was successfully connected to the screen, and as she kept tapping, a green text appeared from the screen.

From the speaker on the left side of the screen, a mechanical welcome from a man is heard.

"Welcome to the Far North and to the Yangtze River Research Station! We uphold the great ideal of maintaining the world's ecological system and jointly creating a community with a shared future for mankind, and strive to add a strong ...... to the history of the earth's development."

Dong Xiang looked at the four of Hao Liangfeng standing behind her, blinked slightly, and then turned his head and tapped the button mechanically.

The male voice continued to echo through the loudspeaker, and Dong Xiang scanned the information above and looked up at the tightly closed mechanical iron door in the distance.

"According to the data that can be consulted above, Battle.net Kaitian is not in the research center, but all the information does not mention that there is a huge underground world below, and this trick to cover up seems to have been done a bit too much!"

Dong Xiang muttered, as if he had found something through the computer, and after taking out another miniature shaped energy battery from the bracelet, he threw it at the controller of the mechanical iron door.

Seeing that it was clinging to the controller's panel, Dong Xiang smiled and pressed the flashing green button on the screen with his index finger.

Bang dang!

With a loud sound, the iron door slowly opened to both sides.

"Whew, it looks like it's done!"

Dong Xiang breathed a sigh of relief and straightened up to look at the scene behind the iron gate.

When the door was fully opened, she walked to the door, stared at the bottomless staircase, and turned to the four of Hao Liangfeng: "So... It's time for us to get to work! ”

Just as Dong Xiang was about to get up and enter the passage, Hao Liangfeng, who had been beside her, stopped in front of her.

Dong Xiang asked with a surprised face, "What's the matter?" ”

"Sister Dong, let's go, you have to guard here, none of us know the specific situation here, and if there is an emergency, we need someone to open the door..."

Dong Xiang understood what Hao Liangfeng meant, nodded and said, "Okay, I'll wait here for you to come back!" ”

Looking at the two sides of Karimu and the Zerg who were in full swing outside, Hao Liangfeng squatted down and said to Hao Lin'er: "Wait for me here, there is something to call me!" ”

"Well, I know, brother, you must be careful......" Hao Lin'er looked at Hao Liangfeng in front of her, her eyes were full of worry, and she grabbed the latter's arm and said.

Hao Liangfeng touched her hair, got up and glanced at Dong Xiang deeply, and saw a smile on the corner of the latter's mouth and nodded slightly.

"Let's go!" The three of them ran quickly towards the open door.

After Dong Xiang saw the figures of the three of them disappear from her eyes, she looked down at Hao Lin'er beside her and smiled: "Let's go, let's go there and see if we can find something useful!" ”

……

In the stairwell, the three of them kept spinning and running around the stairs.

Ouyang Yue passed by a platform, sideways to avoid the water left from the top, looked at the still bottomless passage and asked Hao Liangfeng in front of him, "Honey, how many meters have we come down here?" ”

"It's not very clear, about twenty meters...... Orange cat, can you see ......" Hao Liangfeng shook his head, looked at Tang Tang behind him and asked.

"Eh, you say, is Kaitian really down here?! …… Oh my God, I feel like I'm going to suffocate! ”

At this moment, Tang Tang suddenly spoke, with a trace of unusual excitement in his tone, but the words he said did not answer Hao Liangfeng in the slightest, and then Tang Tang seemed to think of something, and covered his chest with his hands and said to himself.

Hao Liangfeng and Ouyang Yue looked at each other, and they saw helplessness from the bottom of each other's eyes, and they didn't say anything anymore and went down mechanically.

When Hao Liangfeng and the others passed through the stairs that were tens of meters long and came to the bottom floor, a blue light wave was slowly writhing.

The three of them walked out of the open door, and the huge underground world was revealed to them.

On the walls on both sides, a faint white halo reflected off the blue ice on the top surface, causing the entire underground hall to ripple with blue waves, as if in an underwater world.

In the distance, a diamond-shaped pattern was hanging silently on the huge pillar in front of it, and around the pillar, there was a huge pyramid lying on it, and on the four corners, a blue halo like a breath pulsating was flickering over time.

Following the large stairs down the two sides of the pyramid, everyone came to a warehouse door, smelling the faint fishy smell coming from inside, Hao Liangfeng grabbed the retreating counterattack on his side in his hand.

"There's Zerg here!"

Hao Liangfeng and the others looked at the extremely dark passage, with a hint of solemnity in their tones.

"Orange cat, don't get excited here, if there are really Zerg inside, it's not safe here!" Hao Liangfeng looked at Tang Tang, who was stunned behind him, and said softly.

The latter took out the automatic rifle from the bracelet and said to Hao Liangfeng: "I know, I hope these Zerg soldiers don't destroy important information, otherwise I will definitely fight them to the death!" …”

Hao Liangfeng looked at Ouyang Yue again, and saw that she nodded with a bow and arrow in both hands, and then turned around and entered it.

Through the night vision device on the mask, the scattered shelves around are stained with dark green slime from time to time.

Just when Hao Liangfeng just walked around the corner, a vent on the top suddenly fell down.

provoked everyone to aim their guns one after another, and Hao Liangtian looked up at the exposed customs clearance pipe mouth above.

His ears moved slightly, and after repeatedly confirming that he didn't hear anything, he withdrew his gaze and continued to walk forward with Ouyang Yue and the others.

The gradually humid environment displayed on the mask, Hao Liangfeng's ears gradually heard the sound of water 'rattling'.

When Hao Liangfeng and the others passed through the door of a room, they suddenly felt a strange feeling under their feet.

Looking down, the stagnant water that had submerged to the ankles of the three people was constantly rippling with the advance of the Hao scale wind.

In the darkness, Hao Liangfeng watched several finger-sized jets of water seep down from the top.

"This water should be the melted snow water, which has been soaked for many years, and has been unrepaired for a long time, so that it has only been infiltrated!" Tang Tang picked up some water, looked at the analysis on the mask, and said to Hao Liangfeng.

Hao Liangfeng nodded and continued to explore.

Ouyang Yue, who was following behind Hao Liangfeng, looked at the rooms and couldn't help but say, "This institution is also too big... If only there was a map! ”

DiDi ......

As Ouyang Yue's voice fell, there was a sudden sound in their earphones, followed by Dong Xiang's voice: "I heard your voice that you need me, I found something when I was investigating with Hao Lin'er, I hope it will be useful to you!" I've already sent it to you! ”

Hao Liangfeng looked at the blue underground structure map that popped up in the lower left corner of the mask, and the corners of his mouth couldn't help but hook up a smile.

"What the hell is this!"

After Tang Tang finished speaking, he hurriedly called up the map, editing something on it, and then the coordinates of the three of them on the map appeared in the upper left corner of the mask.

Looking at the little red dot on it, Ouyang Yue couldn't help but say, "Oh my God, orange cat, you're awesome!" ”

"It's okay, by the way, Xiaofeng can call me an orange cat, you haven't graduated from the Guardian Academy yet, according to reason, I am still a substitute teacher at the Guardian Academy, remember to call me Teacher Tang!"

"Phew, even my dear can't win, and I'm still a teacher~" Ouyang Yue flipped through the white smoke and said with disdain in his eyes.

Tang Tang's fists clenched, and he held back a sentence after half a sound: "Count you ruthless!" ”

"Don't make a fuss just yet, I hear a lot of other voices!" Hao Liangfeng raised his hand to make a silent movement, and said with a serious face.

When Hao Liangfeng was listening intently, Dong Xiang's voice came from the earphones: "I found the power supply switch on the second floor, I just checked it, the power system of the entire research center is normal, I am turning on the power supply switch through the computer, and it will be ...... right away." All right! ”

Syllable!

As soon as Dong Xiang finished speaking, the lights in the place where the three of them were suddenly turned on, and the bright environment caused the night vision mode on the mask to turn off automatically.

"It's amazing, and it really made the right decision to let you stay there!" Tang Tang couldn't help but admire.

Looking at the surroundings of the goods scattered everywhere, Hao Liangfeng squatted down and lightly touched the green slime on the ground, and couldn't help but say, "This thing just dripped here......"

"Won't it?" Tang Tang and Ouyang Yue heard this, and a look of vigilance flashed in their eyes.

"Wait, I saw the real-time surveillance footage from the underground in the computer, oh my God, I hope it helps you understand the road ahead!"

Dong Xiang's voice fell, and a picture appeared on the masks of the three people, only to see countless Zerg soldiers swarming towards a certain place, and the huge number made the three of them hairy.

"Where are they going?"

"I called up all the monitoring points here, according to the map, the place they are going to now is the core area of the entire underground, although there is no specific role marked on the map, but the space is unusually large, I suspect that the Kaitian we are looking for is there!" Dong Xiang's tone was a little uneasy.

Hearing this, Tang Tang hurriedly raised the automatic rifle in his hand, looked at the two of them beside him, and said with a hint of excitement in his tone: "Then what are we waiting for, let's go!" We can't afford to watch the open sky be destroyed by the Zerg! ”

After speaking, Tang Tang was the first to run along the map towards the core area, Hao Liangfeng and Ouyang Yue had to look at each other, Ouyang Yue muttered, "Dear? ”

"Let's catch up, he's too dangerous alone!" Hao Liangfeng took Ouyang Yue and hurriedly chased after Tang Tang.

……

"Can you imagine that this research center is like a heavily armed fortress! It's too bad! ”

Just as Hao Liangfeng and the others were approaching the underground core area, Dong Xiang's voice with excitement and excitement came from the earphones.

"There are several hidden electronic laser cannons around the entire research center, and the exterior wall of the research center is made of ultra-high molecular weight polyethylene fiber, which can withstand almost several missile attacks!"

Tang Tang, who was running, couldn't help but complain when he heard this: "So this is the legendary turtle shell house!" ”

"What's more, dozens of concealed machine gun muzzles can be set up in the research center room to carry out automatic attacks on the enemy, and not only that, the entire research center also has a self-detonation device, and the power of the explosion can almost cover the area of the scientific research station......" Dong Xiang, who was sitting at the desk, couldn't help but have a faint smile on his face when he saw this.

"Sister Xiang, what are you laughing at?" Dong Xiang turned his head to look at Hao Lin'er, who was puzzled beside him, and said, "I laugh because the higher the protection level here, the more it proves that there is something worth spending a lot of money to protect!" ”

A fine light flashed in Dong Xiang's eyes, and his tone became more affirmative: "So Kaitian is under the ground of this research institute, and it is in the core area!" ”

After being stunned for a while, Dong Xiang, who was sitting in the seat, suddenly thought of something, kept tapping on the computer keyboard with both hands, and said to the headphones: "I'm trying to connect to the security system of this research center now and see if I can help you!" ”

"Then please......" Hao Liangfeng hung up the communication device, looking at the core area on the mask map that was getting closer and closer, and a solemn look gradually welled up in his eyes.
