Seeing that Doug opened his mouth to agree, Chu Han secretly sighed in his heart, it seems that this small water ball-like object in his hand does look extraordinary.

It's just that he is holding this thing in his hand now, and for him, it is just a chicken-like existence, tasteless to eat, and it is a pity to abandon it.

Chu Han had already probed it with his spiritual power, but what made him helpless was that he couldn't find out what this thing was at all.

Chu Han also knew that this thing was the core of the intelligent combat assistance system, but for that system, Chu Han didn't know anything, so it was better to exchange him for it.

For Chu Han, the first task now is to get the information of the scientific research institute, and only in this way can he get more information.

"I wonder when Mr. Lu Daochu wants to go?" Doug looked at Chu Han and asked solemnly at this time.

"Hurry up or not late, speaking of which, I'm already yearning for the Rockefeller family laboratory, so let's go now!" Chu Han looked at Doug at this time and said lightly.

Doug nodded, then got up and said, "Okay, in that case, Mr. Chu come with me!" ”

After that, he walked forward by himself, Chu Han also got up and followed at this time, and then, several more vampires followed behind Chu Han, looking at the situation, it seemed that they were going to go together.

Soon, Doug took Chu Han through the villas, came to the very ordinary villa that Mu Yuhan prompted, and then walked in with Chu Han in stride.

Then, Doug opened the hidden elevator inside and motioned for Chu Han to walk in, and at the same time, the vampire old men who followed Chu Han also slowly walked in, and then, the elevator began to move rapidly.

Chu Han silently calculated the distance of the elevator in his heart, and finally. The elevator stopped falling, and in Chu Han's calculations, the distance from the villa to the elevator to the present was exactly two hundred and thirty-four meters.

In other words, the research base of the Rockefeller family is two hundred and thirty-four meters underground, which is an important piece of information for Chu Han.

You must know that if Chu Han really comes to loot at that time, then the underground research room. For Chu Han, it will be a huge threat.

It's very simple, as long as the Rockefeller family has the courage to break the cauldron and sink the boat, then as long as the space collapses, more than 200 meters of ground sinks, that kind of terrifying pressure, even Chu Han, will die without a place to be buried.

On that day, in the underground grottoes of Yanjing. Chu Han had already experienced it once, if he hadn't been very lucky enough to encounter an underground dark river and escape with the help of the river, he would have hung up that time.

So. When he learned from Mu Yuhan's mouth that the Rockefeller family's research room was underground, Chu Han had already made up his mind that he must come down and take a look.

The elevator stopped landing, but it didn't open for a long time. I saw that Doug suddenly turned his head at this time, looked at Chu Han, and said with a solemn face: "Mr. Chu." When I opened this elevator door, it was our research institute, and I think I had expressed enough sincerity, but before entering, I still have a few requirements to tell Mr. Chu. ”

"Dog, please speak!" Chu Han said lightly at this time.

Doug nodded, and then said: "First of all, I hope that after Mr. Chu enters the research institute, he will not speak, nor ask, in the research institute, it is forbidden to make noise, and when necessary, I will give Mr. Chu an explanation." Second, I hope that after entering, in the designated place, Mr. Chu will be able to return the core to us, otherwise, I would rather die and the net will be broken! ”

Doug's tone was very strong, which made Chu Han feel a burst of surprise, it seems that that the core, in this research institute, has a very important role,

"Okay, since I promised the Doug family master, I naturally won't break the promise, everything, just do it according to the Doug family master's wishes!" Chu Han replied lightly at this time.

Seeing Chu Han talking so well, a look of surprise flashed in Doug's eyes, obviously, he didn't expect that Chu Han would be so easy to speak, did he value this research room so much?

Is he playing the idea of the research lab? Doug thought slowly in his heart, but he didn't have the slightest worry, if Chu Han really hit the idea of the research room, then he would definitely die a miserable death.

"So, thank you Mr. Chu!" Although the thoughts in his heart turned a thousand times, Doug still said with a smile on his face.

Then, the elevator door slowly opened, and Doug and the others slowly walked out of the elevator, and what greeted Chu Han's eyes was a wide hall.

The whole hall is decorated in silver, whether it is the tall columns on both sides, the ceiling on the top, or the surrounding walls, all exude a silver inexplicable metallic luster.

Entering here, Chu Han had an illusion in a trance, as if this was the case when he first entered the puppet hall that day.

This kind of hall is definitely not something that can be built by the existing technology of human beings, especially at such a deep place underground.

Thinking of a series of strange changes such as Doug's successive attitude changes, Chu Han faintly guessed in his heart, maybe Doug and the others were directly taught by prehistoric civilizations, rather than simply inherited.

That is to say, in this research room, it is very likely that there is a survivor of a civilization that does not know what kind of civilization Lu Dao is, and that core may be an extremely important thing for this survivor, which is why Doug is so dignified.

At this time, Doug led the way in front, took Chu Han and them, and walked all the way to the depths of the main hall.

Along the way, Chu Han couldn't help but be shocked in his heart, because he had already noticed that the materials of this hall seemed to be using something bizarre, completely sealing the entire area, and Chu Han's spiritual power was very limited.

At this moment, Doug took Chu Han and walked around a corner and stopped in front of a huge room.

"Mr. Chu, please wait a moment!" Doug turned his head at this time and whispered to Chu Han.

Immediately, after seeing Chu Han nodding, Doug opened the door and entered the room, through a crack in the door just now, Chu Han clearly saw that the decoration in the room seemed to be in European style, with wide curtains, and a series of items such as a slender dining table.

However, Chu Han didn't have time to dig deeper, because soon, Doug came out, followed by an old man who looked wrinkled in his face.

I saw that Doug was holding an object similar to a nameplate in his hand at the moment, handed it to Chu Han, and said indifferently: "Mr. Chu, please bring this, by the way, this is Dr. George from our scientific research base!" ”

Seeing the person next to Doug, Chu Han smiled slightly, stretched out his hand, and greeted politely: "Hello, Dr. George!" ”

However, in his heart, Chu Han sneered, because it was very simple, Dr. George in front of him was Prince George on the top of the mountain last night, the secret leader of the thirteen vampires, and a super powerhouse whose strength had reached the eighth order.

However, at this moment, George restrained his breath and looked like an ordinary old man, if it weren't for Chu Han who had already known his heels, otherwise, he would really be fooled by him.

George didn't have much enthusiasm on his face, just glanced at Chu Han lightly, then turned his head and said coldly, "Let's go!" ”

Under George's leadership, Chu Han and the others continued to walk towards the depths of the main hall, and soon, they came to a silver metal gate.

I saw George step forward and gently press on the gate in front of him a few times, and then, a cyan beam of light suddenly shot down from the top of the gate and shone on George's body.

I saw that on George's chest, a silver nameplate also emitted a slight brilliance, docking with the beam of light.

That nameplate is exactly the same as the nameplate that Doug handed to Chu Han!

Soon, the beam disappeared, the door slowly opened to both sides, George walked in, and then, Doug and they also walked in, Chu Han saw clearly, when everyone entered, the nameplate on their body would flash, obviously, this nameplate is the proof of entry.

Chu Han smiled indifferently at this time, followed behind them, and strode into the gate. (To be continued......)
