Time passed minute by minute, and everyone studied around the stone gate for a long time, but did not find any abnormalities. Detected by the sensors on the wrist, the external air indicators were completely normal, and they removed the mask, saving some oxygen, after all, they did not know the situation below. It's always safe to plan for one more point.

The stone gate was seven or eight meters thick, and they couldn't open it with them.

Zhang Xiaohu and the others felt that they couldn't play a big role, so they simply sat around, ate some food, and rested for a while!

Xiji had no idea of giving up, and was busy nervously with his warriors, holding various instruments in his hands.

Looking at the busy Xiji and others in the distance, Zhao Zixuan couldn't help but say to Zhang Xiaohu: "Alas! Lao Zhang, you said that Xiji really believed Y87564-1, and she didn't know whether the serum bank existed or not, so she dared to lead people to act, is this stupid?"

"I can't stop you if I have food!" Zhang Xiaohu looked left and right, and found that there were no people from the Sacrifice Legion nearby, so he was relieved, and immediately blamed Zhao Zixuan: "Don't say these words again, that person is not a good-tempered person!" ”

"She still needs us now, she won't do anything to us!"

"Don't think so! Don't forget, Yichen and Ma Xiao are still in her hands! We came this time, first, the West Pole has a way to go back, which can send us back to Earth; Second, we need to help her find that serum bank and rescue our partner! ”

"I don't have a partner like Ma Xiao!" Zhao Zixuan refused: "I'm not angry with him, I don't care about the previous things with him, I already give you face, and let me treat him as a partner, I can't do it directly!" ”

"Don't be so stingy! Ma Xiao is also very pitiful! Zhang Xiaohu said: "You don't see him, he is very thin, his arms are dry like branches, and Y87564-4 that pervert also regularly draws his blood to use, think about the ordeal he has suffered over the years, no matter what he has done before, it is very pitiful!" We all came to this place together, although we also suffered a lot of dangers, but compared to what he endured, we are still very lucky, don't care about his previous unreasonableness, it's all over! We should help him! ”

"Your Virgin's heart is flooding again! I don't understand one thing, you said that this Ma Xiao is so critical, how can that Y87564-4 rest assured to bring him out! And I lost it, isn't it ridiculous? These engineers seem to be smart, how can they just do such unreliable things! ”

"You can still be unreliable!" Zhang Xiaohu said with a smile.

"Go, I'm rare to be serious, quick, can you analyze what I said right?" Zhao Zixuan said.

"If you analyze it, it's really like that!" Zhang Xiaohu pondered carefully, and found that Zhao Zixuan immediately grasped the entry point of the problem, he looked at Chenyi in the distance, and continued: "Chenyi said before that they went to Tianzhu Mountain for this serum bank, only to find out that the serum bank was not there, and the serum bank must have a perfect test subject to open it. Maybe it's for this that Y87564-4 will take the risk of bringing Ma Xiao out! ”

"After all these things, you still believe in that goddess?" Zhao Zixuan was surprised.

"Hmmm! I don't believe her entirely, but I can't find any flaws in her words so far! Zhang Xiaohu explained.

"According to me, none of these engineers are good people, and their minds are very bad!" Zhao Zixuan said hatefully: "You! Let's watch out for them! ”

Zhang Xiaohu was still pondering Zhao Zixuan's words, and under the stone gate over there, there was finally a major discovery. One after another screams rang out. "Ahh ”

Zhang Xiaohu and the others immediately ran over and found everyone gathered in front of a stone wall at the stone gate. I don't know who touched the mechanism, but a strange mural appeared on the stone wall, on which a half-length figure was carved out of various strange and messy lines, and from the outside, this person was unusually handsome. The facial features are carved vividly. It was the "Y87564-1!" that had left on his own initiative. ”

Xiji and Chenyi stood at the forefront, staring at Y87564-1 on the stone wall, wondering how the statue of this person could appear here.

"Looks like we're going in the right direction, otherwise there wouldn't be his avatar!" Xiji sarcastically.

"But what's the use of him putting his image here?" Chenyi still doesn't understand the meaning.

"This should be left by the dragon man, you look at the eyes of this portrait, it seems to have been deliberately hollowed out, and the whole portrait gives people a sad feeling!" Zhang Xiaohu stepped forward and expressed his opinion.

"If you say it, I feel a little bit like that! You keep talking! Xiji boasted.

"Let me try!" After Zhang Xiaohu observed, he found that the eyes of Y87564-1 on the mural seemed to be similar in size to the previous gem, so it was better to try it directly. He took the stone out of his backpack and put it on one of the eyes of the portrait, and sure enough, it fit perfectly, but the other eye was still blank. He thought about it for a moment, and simply put his finger up.

"Boom! Rumble! The sound of the huge stone gate moving was resounding. The closed stone door moved slowly, and the two stone doors closed together actually opened, revealing a hidden entrance below.

As the entrance appears, the lights hanging on the walls automatically light up, and a neat passage does not know where it leads.

"Commander-in-chief, this... This is? Zhang Xiaohu pointed to the passage that appeared and asked

"Don't think about it, since there is a road, we have to go on!" Xiji was about to wave his hand and signal his soldiers to go down first, but when he saw the people around Zhang Xiaohu, he hesitated a little.

Yan Cannon glanced at it and said with a smile: "Since you don't want to go down, then let me be a big soldier on the road!" With that, he held the G98 to his chest and walked into the passage first.

Seeing this, Zhang Xiaohu was about to follow closely, but Xiji pointed to him, Zhao Zixuan and King Peter, and said, "The three of you stay next to me, and the others go down!" ”

Everyone entered the passage one by one according to the instructions of the West Pole, and as the last person entered, the stone gate above closed again as if it had been induced.

In the empty passage, there is a dark green luster all around, there are two yellow lights set up every five meters, and the floor is paved with smooth ceramic floors, and many triangular words are densely written on each floor.

The air in the tunnel is still fine, the oxygen level is higher than the outside, and the calcium content in the air is slightly abnormal.

There are also some beautiful murals on the surrounding walls, all painted with glaze and painted with transparent glue paint.

"It's so weird here! Stay safe, everyone! Xiji held the photon gun, and the light on his shoulder kept glancing.

As the crowd moves forward, more strange things keep appearing. They found that at each distance of the passage, there was a separate room, the floor of which was painted a blinding red, and there were a variety of dry corpses crouching in the center of the house, which were recognizable from the size and height of the dragons. On the main wall of the room, strange black objects of various sizes hang on the walls, surrounded by various triangular characters.

Puzzled and confused by these things, they finally passed another room and looked at a small irregular black object on the wall. Xiji had an angry expression.

"Commander-in-chief, do you know what these things are?" Zhang Xiaohu asked.

"If I'm not mistaken, these things nailed to the wall are actually the remains of our engineers, but they are too small, and they are dried up like this, I didn't even see it just now!" Xiji said angrily.

"Ahh Zhang Xiaohu was surprised.

"Team leader, is this what it is?" When Chen Yi heard Xiji's words, he immediately recognized the things on the wall.

"Yes, it's an engineer's skull!" Xiji said coldly: "I just don't know whose it is, we people have not been in touch with each other for too long, and I don't know which unlucky ghost died in the hands of these dragon people!" ”
