But the other party might be very happy in his heart.

Zhang Yunming took Li Yu through Qishi Mansion, came to the back mountain, and then came outside a cave.

Outside the entrance of the cave, there were heavy troops guarding him, and Li Yu even noticed the formation.

"Your Majesty, Mr. Ou is still studying inside. We are here just the right time!"

After opening the gate of the cave, Zhang Yunming smiled on his face.

Li Yu didn't say much, just nodded and followed.

Chu Xian followed behind him, his body surging blood and his eyes were alert and he was ready to take action at any time.

Seeing this scene, Zhang Yunming's eyes flashed and wanted to say, "This is the important place of Qishi Mansion, which is very safe."

But when he thought of Li Yu's identity, he still didn't say anything in the end.

There is a long corridor in the cave, with glittering glass lamps on both sides.

Chu Xian looked at him, and his eyes slowly became confused.

He began to think that the glass lamps were filled with oil lamps, but after a closer look, he found that there were oval stones inside.

Zhang Yunming walked in front, but kept paying attention behind him.

After seeing Chu Xian's puzzled eyes, he explained with a smile: "Chu Dajian, this thing is called Yaozhan, and the one that shines inside is Yaoyu."

"Yaoyu is born to shine, but its brightness and time are not lasting and are uncontrollable. Later, after Mr. Ou's research, he learned from many drawings and achievements provided by His Majesty."

"In the end, the synthesis of Yaoyu was achieved, which improved the brightness, usage time, and achieved safety and controllability."

"Now, the main venues and passages of Qishi Mansion have been replaced by Yaozhan. Just wait for us to increase the yield rate, we can quickly promote it nationwide."

Chu Xian was shocked. He never expected that this small lamp would actually hide so many things.

But what he cared about the most was the other person's last words.

"Master Zhang, you said that this item will be promoted nationwide in the future. I wonder how much it is? Can ordinary people afford it?"

If this Yaozhan can enter the homes of ordinary people...

hiss!

Chu Xian really couldn't imagine what a shocking scene it would be!

When Zhang Yunming heard this, his smile fainted slightly and shook his head and said, "Although the price of Yaozhan has not yet been determined, its cost is not affordable by ordinary people."

Sure enough...

Chu Xian sighed in his heart, it was because he thought it was so beautiful.

In fact, just looking at the glitter cover of the shining glass is not something that ordinary people can use.

"The Chu Dajian doesn't have to be disappointed. Although Yaozhan may not be available to ordinary people, the future may not be certain."

Zhang Yunming smiled on his face and said, "We have made new progress in the development of Liuli, and the cost of Yaozhan will definitely drop by then."

Chu Xian had recovered from his calmness at this time. He nodded and said seriously: "In this way, I have to work hard for you, Lord Zhang."

"Haha! There is no hard work, this is what our Qishi Mansion should do."

Zhang Yunming laughed. He didn't mean to pretend to be conscious.

But I really think so in my heart.

Don’t look at how much he hates him in front of Li Yu, and he has to study the cost.

In fact, the funds from Qishi Mansion are sufficient.

Working under the pressure of no resources, living and environment, the atmosphere of the entire institution is very friendly.

In such an environment, the original intention of the people in Qishi Mansion can be better maintained.

Li Yu walked in front, listening quietly to the conversation between the two, silently silent.

Only in places that ordinary people cannot easily detect, the corners of their mouths will rise slightly.
