Hao Zhi stepped forward alertly and blocked everyone behind him. He looked up at the tall guy. Hao Zhi, who was more than one meter eight, had just passed his waist and looked like a child in front of him.

"Who are you?"

The tall giant did not answer, glanced at the people with indifferent eyes, and then shook his head: "you are not the mission!"

"What mission person?" Hao Zhi feels strange. It seems that no one has ever set foot in the underground world. What does this person do?

"Did those people come with you?" he didn't answer. He seemed to disdain to communicate with Hao Zhi. He simply raised his chin and pointed behind Hao Zhi.

Hao Zhi looked back and saw a ball with colorful light falling slightly in the air. It was the four-dimensional force field under the waterfall that day!

It's the one who just followed the team!

At the moment, it agitated its round body and suddenly contracted. It even "vomited" Lynch and Ma Junjie. They had already lost consciousness, fell silently from the air more than two meters high, and lay on the ground.

Then the colorful ball of light floated towards the giant and hovered not far from his right shoulder.

"Can you manipulate this four-dimensional space?" Professor nado asked in surprise.

"Space?" the man asked, "it's my pet..."

"Biology?" Professor nado was surprised again, a four-dimensional creature?

"Professor, I don't think this guy is human. It is estimated that he is human in the underground world. It may be very dangerous," Hao Zhi whispered to Professor Naduo.

"Maybe... However, this is the first communication between human beings and unknown civilization, and we can't give up easily!" the professor seemed a little too excited. Ignoring the danger, he took a few steps forward, walked across from the guy and looked up at the giant.

"Are you a civilized creature in the underground world?" Professor nado asked as friendly as he could.

"There is no civilization here!" the giant's eyes showed a boundless desolation. "I am the guardian of the world. For thousands of years, there are only me and my pet waiting for the emergence of my successor. Unfortunately, you are not!"

"Why do you know our language?"

"Your language?" the giant asked puzzled. "I use the ancient continental language inherited from generation to generation. If we can communicate, it shows that you are a branch of ancient continental civilization and you inherited the language left by my masters!"

"In other words, we follow the same department! We are the descendants of the same civilization!" Professor nado added excitedly.

"Why did you come?" the giant slowly squatted down his huge body, like a hill. His head was deeply buried in the middle of his knees, not looking at the many professors.

"We... We found the skeleton sculpture at the entrance by chance, so we were curious and found it here..."

"You stole the integrated information body?"

Professor Naduo was stunned, but he quickly realized that it should refer to the crystal skull. He guessed right. The thing itself is an information integration device, which is used to store data, similar to a computer floppy disk.

"We don't know it has a master... Anyway, we got it, but we don't know how to use and read it. Can you teach us?"

"You don't have the qualification to inherit. Leave the crystal. Go back!" the giant shook his head and replied stubbornly.

"If, if you need any inheritance conditions, tell us that we can work hard!" Professor Naduo asked anxiously, unwilling to give up.

Suddenly, the giant raised his finger and a strong wind swept across his face. Hao Zhi reacted very quickly. He grabbed the professor, hugged him and dragged him aside. With a hula, a shallow trace appeared on the ground, like being cut by a scalpel.

"What a strong momentum!" Jiajia was interested as soon as she came down.

"Leave the crystal, or you will all be buried here..." the giant raised his towering brow slightly, and his words showed his intention of killing.

"Stay? We didn't bring it! We keep it at the base!" Hao Zhi explained to him.

"Leave the crystal, or you will all..." the giant ignored it and repeated it again.

"The giant is a little silly and can't understand people!" He Gang sighed.

"No... no, no..." Hao Zhi suddenly had a flash in his mind and tentatively asked the giant, "summer is coming?"

Everyone was stunned. They didn't understand why Hao Zhi suddenly started a family relationship with the giant.

Hearing this, the giant slowly raised his huge face and showed infinite sadness: "it's another year... For thousands of years, I've been guarding the dead world alone, waiting for the arrival of the mission. Unfortunately, you're not..."

"This guy is quite emotional!" Du Danhua chuckled.

"With a bang, all the children in the hall?" unexpectedly, Hao Zhi suddenly said.

"Information analysis error!" after waiting for a long time, the giant replied stupidly.

"What are you talking about?" Song Xiaojia was confused.

"The boys in our class asked slang when they met in the Internet cafe, which means to ask whether there were many people going during the evening self-study, and whether they called the roll..." Hao Zhi smiled, "Professor, this guy may be just a robot!"

"Ah? How do you know?" many professors were surprised.

"At the beginning, we talked to him as if he was very fluent, but in fact, he just responded to our words according to the things stored in his knowledge system. He is a complex program, but he does not have the ability to think. I guess he guarded the door in this place, or, like an examiner, verified the people who came here to see who With the qualification of the so-called mission person, perhaps those who have obtained the qualification can unlock the secret of the dungeon! "

Hao Zhi even talked a lot, which surprised Jiajia.

"I just asked him something he didn't understand. If someone jumped out of the scene at the moment and didn't have logic, or even deduction, he couldn't react!" Hao Zhi raised his eyebrows and asked Jiajia, "Do you remember that when Xu zhe introduced Xiaobing to us, he once told us about artificial intelligence. The biggest feature of rigid artificial intelligence is that it will make quite rigid responses to almost the same environment and dialogue. I don't believe you see."

"Summer is coming?" Hao Zhi turned and talked to the giant.

"Another year... For thousands of years, I have been guarding the dead world alone, waiting for the arrival of the mission. Unfortunately, you are not..." the giant answered the same sentence.

Jiajia suddenly realized that this was not the question Xu zhe asked when he tested Xiaobing! Hao Zhi used flowers to offer Buddha here.

"But it's troublesome..." Hao Zhi reluctantly said, "if this guy really has a little brain, it's better to discuss. He's most afraid of this dead procedure. You don't meet the conditions. He won't accommodate you and can't hand in the crystal. It seems that we're all going to plant here!"

Behind him, the giant's eyes lit up and slowly stood up
