After Lingchu thought for a moment, he found some wooden boards, made a circular platform, and then hollowed out a circle in the middle.

The black stone was polished again.

This kind of gem is too hard to polish and requires special polishing tools.

Fortunately, Yan Chen had researched these gems and bought a set of polishing tools before returning.

Lingchu took a professional polishing tool and quickly polished the black gemstone to be smooth and round.

Then, take out a small hole in the middle.

Along the small hole, Lingchu carved the spell of the spirit detection array on the black gemstone bit by bit.

She has done these things many times and is very skilled at them.

They say practice makes perfect and saves time.

This is not true at all.

Lingchu's carvings never take much time.

But it still took her most of a day to complete the entire black gem carving.

She didn't finish carving until after nine o'clock in the evening.

After sitting there and carving without moving for six or seven hours, Lingchu felt that his neck was about to break.

After carving the last stroke, she shook her neck and exhaled, "It's finally done."

Yan Chen, who had been silent all this time, handed Lingchu a glass of water and said, "Drink some water and rest."

Lingchu said hello, took it, and asked casually: "Senior Yan Chen, how was your test result?"

Yan Chen said: "I don't have any problems here."

After all, with Lingchu's system support, it was very easy for Yan Chen to do these things.

It worked the first time.

only……

"But you still need to connect your spirit detection array and try it to see its sensitivity and accuracy."

Lingchu nodded, "I'm almost done."

Lingchu said, took a big gulp of water, then put the water bottle down casually, picked up a piece of talisman paper, and started to draw talismans.

She added a spirit-gathering talisman inside, stuffed it into the small hole in the center of the black gemstone, and sealed it with cinnabar.

At this point, it's almost half done.

Lingchu then placed the round black gem into the hollowed out part in the center of the platform.

The size is just right.

Perfect fit.

But there are still many things that need to be sorted out.

Lingchu squatted beside the platform again and got busy.

Seeing that she seemed to be still busy, Yan Chen glanced at the time on his computer and said, "It's getting late. Do you want to go back and rest first?"

Lingchu didn't even raise his head: "No, there's not much left. It will be done in another hour at most."

Yan Chen paused after hearing this, "Then I'll order some takeout? You haven't had dinner yet."

Speaking of dinner, Lingchu raised his head, looked at Yan Chen, and said with some embarrassment: "I'm sorry, Senior Yan Chen, I was so busy that I forgot to treat you to dinner."

It’s not good to ask people for help and then leave them hungry.

Lingchu immediately said: "You order takeout, Senior Yan Chen, you can order whatever you want. It's my treat, and I'll reimburse you later!"

Yan Chen didn't care about this, "No, I'll take the order."

After finishing speaking, he took Duan Nao and left.

When Lingchu saw this, he didn't care to talk about anything else, so he planned to talk to Yan Chen about it later.

Immediately, she lowered her head, dipped her fingers in cinnabar, and continued to draw spells on the floor.

With the round black gemstone as the center, it spreads around to expand the spirit detection array and make it more detailed and complete.

Yan Chen ordered takeout, and while waiting for the takeout to arrive, Lingchu finally finished the drawing.

The talisman array is completely completed.
Chapter completed!
