Ning Xizhen tapped her head lightly, "This door seems to be a lock. It cannot be entered without a specific method of opening it."

"clever."

Ye Fan looked at the wooden door, "This door is not simple, it is a bit like Ou Zhizi's work."

"Is it the descendant of that magic craftsman?"

Ning Xi is not unfamiliar with the name Ouzhizi.

On the Internet, Ouzhizi has a great reputation.

The descendants of the Shenjiang Ou Ye were proficient in various mechanisms and once posted a video on the Internet, and the meticulousness of the mechanism was amazing.

Such talents were quickly requisitioned, and since then Ouzhizi has become a legend.

Ye Fan nodded, "Besides him, I can't think of anyone who can create such a wonderful opening mechanism."

Ning Xi was puzzled, "Brother, the current technology level is very high, and various anti-theft technologies are emerging one after another. Why do you still use this most primitive mechanism?"

"Mechanism will never go out of date, because its advantages will never be replaced by technology at any time."

Hearing this explanation, Ning Xi was even more confused, "But the anti-theft technology now is so powerful, far exceeding this ancient mechanism."

Ye Fan patiently explained: "High technology is good, but it also has its drawbacks; once someone invades the control system, the so-called high technology will become a bunch of decorations. The best way is to use both, and with the protection of experts like the Red Group members, you can deal with whatever happens."

Ning Xi suddenly realized, "I understand."

Hongwu put away the pass, "The two academicians can take away three items from it, please come in."

Ye Fan nodded, hugged Ning Xi's shoulder and walked in.

The wooden doors automatically close.

Ning Xi was startled, "Oh? Why do we get out later?"

Ye Fan pointed to the infrared scanners on both sides, "It's hard to come in, it's easy to get out."

When talking, look forward.

The Zhenbao Pavilion is very large, covering an area of ​​at least thousands of square meters. Redwood columns stand, rows of metal shelves are neatly arranged, and square boxes are placed on the shelves, and there are signs next to each box.

At first glance, it looks like a huge warehouse.

Ye Fan had heard of Zhenbao Pavilion before, and this was the first time he came. He pulled Ning Xi to the nearest shelf, "Look at it casually, the box can be opened, but don't touch the things inside at will."

"Um."

Ning Xi nodded obediently.

She squatted down and picked a box and opened it. The next second, her eyes widened.

In the box, a ruby ​​that is a little larger than an egg is crystal clear and bright red.

"There are such a big ruby ​​in the world?"

Ye Fan squatted down, "I have never heard of it. If this ruby ​​flows out, it will be no problem to sell billions easily."

“So beautiful.”

Girls are naive to things like gems, so they have no resistance.

Ning Xi is no exception.

Ye Fan looked at her liked appearance, without saying a word, picked up the ruby ​​in the box and put it in his pocket, "I want one thing, I'll give you the remaining two pieces. This is the first thing, I can choose another one; choose slowly."

"elder brother."

"Um?"

Ning Xi raised her little face and kissed Ye Fan's face in confusion, "Xiao Xi loves you so much!"

She stood up, clenched her fist with her right hand and raised it high above her head, "I'm going to sweep it!"

As soon as he finished speaking, he ran forward quickly.

Ye Fan was amused and crying, "Slow down, be careful not to bump into yourself."

"I know, brother, go find your own things, don't delay Xiaoxi's sweep."

Hearing the sound from afar, Ye Fan shook his head and laughed.

This girl only has one chance to choose, so how can she talk about sweeping?

This stupid der!

However, Ning Xi was so happy that Ye Fan felt that the decision to bring her here today was very correct. He stood up and looked at the distribution map on the pillar, and quickly found the medicinal material area and walked over without any haste.

Ganoderma lucidum, evening grass, Eucommia ulmoides, Polygonum multiflorum...

These are not the key points, the key points are the year of these medicinal materials.

Even though Ye Fan had made some psychological preparations, he was shocked.

After a glance, these precious medicinal herbs in front of me were not less than three hundred years old!

horrible!

Ye Fan took back his mind and quickly searched on the shelf.

One shelf, two shelves...

Finally, on the third floor of the fourth shelf, I found a row of boxes containing ginseng.

From left to right, there are eight boxes in total.

Three hundred years!

Three hundred and seventy-two years!

…

Five hundred and sixty-eight years!

When Ye Fan saw the penultimate box, he smiled.

Just it!

He looked to the right habitually, and when he saw the sign next to the last box, his eyes almost popped out.

Nine hundred and ninety-nine years!

Damn—
Chapter completed!
