This underground passage is about 1.5 meters high and 60 centimeters wide, and it is obviously newly excavated, because there are still traces of just excavation on the wall of the tunnel.

The bald young man led a few people through the tunnel quickly, and from time to time there would be a huge vibration on the ground, so that the roof of the cave would fall from time to time, making everyone a head of dirt.

"Little bald head, where are we going, and how far do we have to go?"

Shen Min followed behind the bald young man and asked as he walked.

"Don't call me a little bald head, my name is Li Qiang!" The bald young man said dissatisfiedly.

"Okay, Li Qiang, where are we going?"

"You'll know when you go."

"How far is that?"

"It's almost there."

"How far is it coming?"

······

Shen Min kept asking the bald young man some questions, and the bald young man didn't say anything detailed but simply answered, until after walking for more than half an hour, several of them finally came to the end of the tunnel, but this end was not back to the ground, but came to a huge underground space.

This underground space is quite huge, like a large underground arsenal, and the exit of this tunnel is just in the middle of this underground space, and there is a distance of nearly 10 meters down, and the overall height of this space is definitely more than 20 meters.

Cheng Ming and the others walked out of the passage, standing on the plank road around the underground space and looking at the middle, there were all kinds of weapons, vehicles and some experimental supplies in the center, and many scientists in white coats and soldiers in military uniforms kept walking through it, very busy.

On the walls of the space, five layers of plank roads are arranged, and each floor has many rooms and entrances that lead to nowhere.

"Li Qiang, you're back, how is the task completed?" As soon as Li Qiang wanted to introduce the situation here to a few people, he saw a middle-aged man wearing a white coat and a pair of black-rimmed glasses walking over.

"Who are these?" The middle-aged man looked at the few people behind Li Qiang and asked curiously, but when he saw the old man of Yuanyang with white hair, he was stunned, and then called out with surprise on his face.

"Yuanyang Zhenren, you're back!"

Being called by the middle-aged man like this, Lao Dao also turned his head to look at the middle-aged man, and then said with great surprise: "Academician Wu, why are you here?" ”

The middle-aged man known as Academician Wu walked quickly to Lao Dao, grabbed Lao Dao's hand, and said excitedly: "I was transferred here to do weapons research a year ago, and your old man has been gone for more than two years, and there is no news, but we are in a hurry." ”

"I'm sorry to worry everyone, but I'm not back, and I'm also bringing back a few guests with the same status as me." Lao Dao said and let go of his body and showed Academician Wu a few people behind him.

"You mean, these guys too?" Academician Wu looked curiously at Cheng Ming and the four behind Lao Dao, and asked Lao Dao as if he had pointed out.

"Well, this is Cheng Ming, this is Shen Min, these two little guys are Cheng Ming's children, Ke'er and Lin Fan." Lao Dao introduced the four people to Academician Wu respectively.

"They're all?" Academician Wu listened to Lao Dao's introduction and looked at the four of them in surprise.

"No, no, there are only Cheng Ming and Shen Min." Lao Dao explained.

"Then what do they have~" Dr. Wu is a scientist, and the common problem of scientists is that as soon as they meet someone or something they are interested in, they like to ask questions regardless of the occasion.

"Academician Wu, we have been traveling all the way, you can arrange a place for us to live first, and then talk about it in detail."

Seeing that Lao Dao interrupted him, Academician Wu immediately realized that what he asked was a bit too inappropriate, and hurriedly said.

"Real person, you see that as soon as my curious old problem strikes, it's a little bit of that, hehe. Let's go, I'll take you to where you live first. ”

After Academician Wu finished speaking, he turned to Li Qiang and said, "Li Qiang, you go and summon all the personnel above the director level to the conference room, and the meeting will start in an hour." ”

"Okay~ Okay, I'll go." When Li Qiang heard that Academician Wu asked him to convene a meeting, he knew that he might bring back a few big people this time, and he didn't delay, so he hurriedly ran to inform the personnel to hold a meeting.

Academician Wu took a few people to the second floor of the space and arranged two rooms with two beds for them. Naturally, Lao Dao and Cheng Ming are in the room, and Shen Min and the two children are in the room.

After arranging rooms for a few people, Dr. Wu took a few more people to the cafeteria and asked the cafeteria to prepare meals for a few people.

Due to the sudden arrival of the spider mecha and the sudden appearance of Li Qiang, a few people didn't actually eat much, plus they walked in the tunnel for more than half an hour, and a few people were already hungry.

After a few people finished eating, Li Qiang also came to the cafeteria and told Dr. Wu that the personnel had arrived.

"Let's go, Academician Wu, let's go to the conference room and see if there are any other old friends who are also here."

Lao Dao got up and said to Li Qiang: "Li Qiang, please take these two children back to the room and let them rest first." The two children were also exhausted from running all the way. ”

"Okay, real person, little brother and little sister, brother will take you to bed." Li Qiang beckoned the two little guys to leave, but Ke'er had never seen so many people since he was a child, and looked at Cheng Ming a little timidly at this time, Cheng Ming looked at Ke'er with a smile and said to her.

"Go, go rest with your brother Li Qiang, dad and grandpa they still have some business, and dad will be back in a while."

Ke'er has been very well-behaved since she was a child, and when she saw Cheng Ming say this, she also knew that Cheng Ming and they had something important, so she nodded obediently and followed Li Qiang.

"What a well-behaved and lovely little girl, Mr. Cheng is so blessed." Academician Wu's eyes were full of affection, and he looked at Ke'er who was far away, and turned back to Cheng Ming and said.

Cheng Ming also said proudly: "Giving birth to Ke'er is also the proudest thing in my life. ”

"Okay, don't be sour, let's go, let's rest early after meeting with everyone, I'm tired too."

Dr. Wu led several people to the conference room, where five people were seated, four of whom were wearing white coats and one of whom was wearing military uniforms.

As soon as Lao Dao walked into the conference room, several people immediately stood up and looked at Lao Dao excitedly.

Lao Dao looked at a few people and was full of joy: "Academician Chen, Academician Wang, Academician Liu, Academician Li, your brother is here." ”

After speaking, the four of them shook hands one by one.

Lao Dao looked at the soldier again, and when the soldier saw Lao Dao looking at him, he immediately saluted and said; "Yuanyang is really good."

"Yo, Xiao Chang, I've been promoted, it's time to call you Major Chang."

The soldier said embarrassedly, "Don't laugh at the kid if you're a real person." ”

Lao Dao patted the soldier's shoulder and said with a smile: "I have long said that your kid has good official luck, and I said it, hahaha." ”

Lao Dao took Cheng Ming and Shen Min to the opposite position of the conference table with a smile and said, "Okay, everyone sit down, they are all old acquaintances, and they are so polite." After speaking, he sat down with a big smile, and several people sat down when they saw Lao Dao sit down.
