"Does this thing work?" Zhao Feng asked with a frown.

"Of course it works, I'm not recommending you the kind of waste seismograph of the 21st century!" Qing'er glanced at Zhao Feng.

"What's that? Besides, we can't do electronic now, even if it's the kind of the 21st century, we have no way to develop it now! Zhao Feng said.

"Hehe, you can never imagine this, this is a new type of seismograph researched by a later scientist, which predicts earthquakes based on vibration and the laws of crustal motion, and does not involve electrons at all!" Qing'er smiled slightly. (I don't know if there will be one in the future, but I definitely don't have it now!) ）

"Oh? And this kind of goodies? Zhao Feng was slightly stunned, such a seismograph is simply an artifact, "So how accurate is his prediction?" ”

"This ...... There is still room for improvement, only 70% accuracy! Qing'er said with some embarrassment.

"Seventy percent...... Well, it's already good! Zhao Feng nodded, you know, predicting an earthquake is very difficult, sometimes people can tell from the reaction of the animals that there is going to be an earthquake, but the specific time, even the animals, may not be able to predict accurately! If you want to predict earthquakes with instruments, you can imagine how difficult it is!

"Where is the drawing, I'll see, what kind of artifact it is!" Zhao Feng was a little impatient.

"Hehe, I've already sorted it out for you, and there are some others, you may not need them now, but you'll be able to use them when the time comes!" As she spoke, Qing'er took a stack of drawings from her bedside table, looked through them for a long time, and finally found the drawings and handed them to Zhao Feng.

"Huh?" Zhao Feng took the drawing and looked at it carefully.

The more he looked, the more frightened Zhao Feng became, this ...... It's amazing how someone could come up with such a solution! It's really incredible!

"It's amazing!" After Zhao Feng saw it, he tried to think about it in his mind, and couldn't help but sigh.

"Of course!" Qing'er said.

"Alright, I'm going to the blacksmith now!" With that, Zhao Feng left the system space.

came to the blacksmith shop, and Zhao Feng directly found Master Wang.

"Lord, I don't know what's the matter?" Master Wang knew that Zhao Feng usually didn't come to the blacksmith shop, but when he came, there must be something, and it was definitely a good thing, maybe he had some kind of novel ideas.

Therefore, every time Zhao Feng came to the blacksmith shop, Master Wang was very happy, basically Zhao Feng had what kind of new inventions, and wanted to give them the drawings and let them develop!

No, Zhao Feng took another piece of paper in his hand, it looks like it should be a drawing, right?

"Well, this is a seismograph I came up with, you can take a look first!" Zhao Feng said a little cheekily. But Zhao Feng can only say this, otherwise, where did this drawing come from?

"Seismograph?" Master Wang will take the drawings suspiciously, in this era, the geodynamic instrument is basically a household name, if it can be made better than the geokinetic instrument, it is simply unimaginable!

"Well, take a look, this is not as simple as a geodynamic instrument, this can predict earthquakes, and the accuracy rate can basically reach more than sixty percent!" Zhao Feng nodded, he also knew that Master Wang didn't believe it very much, and he said that the accuracy of the prediction was a little lower, but what could be done?

"Prediction!! The accuracy rate can be more than 60%!! "Master Wang couldn't believe what Zhao Feng said!

"Hehe, how is it specific, it's still that sentence, once it's made, you will know how it works!" Zhao Feng smiled slightly, he knew that if this thing only looked at the drawings, it was very ordinary, and the subtleties in it might only be seen by Zhao Feng! But this does not hinder anything, as long as it is made, it will be clear what the effect is!

"Good! Good! Master Wang nodded again and again with some excitement, "Don't worry, my lord, within five days, this thing will definitely be made!" ”

"Well, but don't be too anxious, this thing is very precise, and you can't make a little mistake!" Zhao Fengdao.

"Don't worry, my subordinates will supervise the whole process!" Master Wang said.

"Well, I don't have to worry about you, but pay attention to your body!" Zhao Feng glanced at Master Wang quite worriedly, you must know that Master Wang is already seventy years old this year!

"Hehe, don't worry, old man, I still want to work for my lord for a few more years! You won't die so easily! Master Wang smiled and patted his chest.

"Haha, that's good!" Zhao Feng laughed and left the blacksmith shop.

"Quick, tell Ma Jun and them all to come over, there is something to do again!" After Zhao Feng left, Master Wang hurriedly shouted, his voice was very excited.

……

After two days of nothing, the first batch of jade was finally delivered to the palace.

Feeling the abundant aura emanating from the jade, Zhao Feng couldn't help but feel shocked.

"Lin Zong, you go and call Lin Heng and all of them, including my master, Tong Yuan, too!" Zhao Fengdao.

"Yes!" Lin Zong nodded and turned to leave.

"Brother Feng, the color of this jade is very good!" Qing'er smiled.

"Well, that's good!" Zhao Feng nodded, "Qing'er, how much jade do you need to arrange the Spirit Gathering Array?" ”

"To tell you the truth, if it's a complete array, these jade stones won't be enough!" Qing'er shook her head and said.

"Huh?" Zhao Feng couldn't help but be slightly stunned, when he studied the formation diagram before, he didn't seem to find that he wanted so many jade.

"Yes, even if you come again, it's not enough!" Qing'er nodded, "The drawings I gave you before were just a simple Spirit Gathering Array, and I didn't give you the complete Spirit Gathering Array blueprints!" ”

"......" Zhao Feng was speechless for a while after hearing this, "Why didn't you tell me this?" ”

"Hehe, I just want to tell you that this Spirit Gathering Array of yours can only play the role of gathering spirits, and if there are too many people, I'm afraid it will not be able to make ends meet!" Qing'er said.

"Won't I be able to join Jade at that time?" Zhao Fengdao.

"Well, that's good, but you have to keep an eye on it!" Qing'er smiled slightly. "Don't worry, I'll keep an eye on it for you, too!"

"So what are you talking about?" Zhao Feng glanced at Qing'er.

"People just want to tell you that there is still a gap between this and the real Spirit Gathering Array, and the real Spirit Gathering Array doesn't need to consume jade at all!" Qing'er said.

"Okay, but when I set up the formation for a while, I don't have to ask you for help!" Zhao Fengdao.

"Don't worry, I know!" Qing'er nodded, a strange look shining in her beautiful eyes.
