The days have returned to normal, and Ling Li has been in the pharmacy college more recently, mainly brushing books.

He rarely attends the classes of the Formation Pattern Academy, and occasionally listens to the class, which makes the students feel a little surprised.

Zhong Ruonan, the mentor, basically treats Ling Li in a free-range manner, and he doesn't care much, but Ling Li will stay in the laboratory for half a day every time he hands in a task to study the latest chip manufacturing technology. He originally expected Mr. Zhong to come out with a smartphone chip first, but now that he looks at it, his expectations are still too high.

Source energy chip technology is changing from analog signals to digital technology, but there is still no new breakthrough.

It is better to ask for others than for himself, he is simply trying to cultivate the "artificial intelligence spirit puppets" of Xuanchen Star Mansion's Dan disciples and craftsmen, so that they can learn new pharmaceutical and refining techniques.

This "intelligent puppet" has a strong learning ability, which is actually equivalent to forty-nine advanced industrial robots, and can also self-evolve and improve the knowledge learned. It's just that before learning the technique, Ling Li needs to demonstrate it himself.

It's a bit of a duck on the shelf.

In many operations, Ling Li has made mistakes.

Fortunately, these puppets, led by Guibo, are able to correct themselves.

When it comes to the precision of operation and control, humans can't compare with robots.

Now visiting the pharmacy has become another of Ling Li's "hobbies", he needs to help the witch clan collect the medicinal materials and refining materials needed for cultivation.

Qinfu City is densely populated, and because it is the most industrially concentrated city in the entire northwest region, the air quality has always been poor. For cultivators, they generally choose to live and cultivate outside the city. As his cultivation progressed, Ling Li's feelings about the polluted air here became clearer and stronger. That is, without spiritual power detection and analysis, just by breathing with the sense of smell, you can feel the turbid breath around you.

So, when he doesn't have anything to do, he doesn't like to wander around the city very much.

The medicinal herb market in Qinfu City is in the north of Xicheng, close to a small commodity wholesale market, and it can be regarded as a relatively prosperous commercial area. The inside of this medicinal herb market is similar to a farmers' market, the façade is not large, and there are stalls in front of the door. Under the canopy in front of the store, there are also textile bags filled with medicinal herbs. The flow of people in the market is not too much, after all, it is not a place to sell medicines, and the sales are mainly aimed at pharmacists.

Ling Li parked the car outside the market and followed the flow of people into the medicinal herb street. The streets are lined with shops, and in front of the doors of these shops, there is also a row of smooth and neat bluestone rental cases, on which are placed all kinds of goods, at a glance, there are thousands of such rental stalls alone.

These stalls are not only medicinal materials, but also almost all the commodities necessary for martial arts cultivation: spiritual materials, elixirs, ores, furnaces, all kinds of spiritual weapons, utensils, and practice secrets...... It's dazzling, but it's also dizzying.

Ling Li walked between the various stalls, and there were all kinds of shouts all around, and slowly looked all the way over, the items on the stalls were not fake, but most of them were yellow-level spiritual materials and elixirs, and there were not a few things that he could look at, and after walking for a while, he was already interested. He has enough eyesight now, and he is not afraid to be deceived.

Stopping and walking all the way, he also bought some spiritual materials and elixirs unique to the Northland, although these things are not of high grade, they are also rare on weekdays.

After turning around for a while, it was really difficult to find any good things on the stalls, and just came to a five-story shopping mall-style store, Ling Li thought: "Let's go upstairs and take a turn, the things in the general business house are better, and the quality is guaranteed." "Those who can afford to open big stores in the medicinal herb market street are generally big forces or some century-old stores, and the prices of the goods sold are higher than those outside, but fortunately, the reputation is guaranteed, and they will not be deceived.

He is now standing in front of a trading house called Wanbaolou, which is also a relatively large commercial house in this medicinal herb street in terms of scale. So I started to turn around and walk towards the gate on the first floor.

When he was about to enter the gate of Wanbao Tower, his divine sense swept over a stall not far from the door, and suddenly felt a powerful source power fluctuation emanating from the stall and disappeared in a flash. This energy fluctuation time was extremely short, but it happened to be noticed by Ling Li. "Huh?" Ling Li stopped, turned and walked towards the stalls.

He first picked a few ice lotus flowers and snow ginseng from a nearby stall very casually, and then moved to the target stall. On the bluestone slab of this stall, there were a hundred and ten kinds of items, among which there were several dried elixirs that made Ling Li feel a little surprised, "Half immortal drunk, crane spirit root, earth blood exhausted...... Alas, what a pity! Ling Li couldn't help but secretly scream in his heart that it was a pity, these medicinal materials were very rare, most of them were Xuan-rank high-grade elixirs, and some could even be included in the ground-level elixirs, but due to poor preservation, most of the medicinal effects were lost, and they had almost become waste.

But these medicinal materials were not Ling Li's target, his eyes did not stay on these elixirs for too long, but continued to search on the stone case, and finally fell to the corner, where there was a palm-sized metal fragment, the surface was rusty and mottled, looking at the shape, it should be a Dan furnace fragment, but if you feel it carefully, it reveals an ancient and reckless atmosphere. Ling Li's eyelids jumped, knowing that this was exactly what he was looking for.

"How much do these herbs cost?" Ling Li pointed to the elixirs that were about to expire and said.

"Little brother has good eyesight, it seems that he is a knowledgeable person, let's not hide it from you, according to the Xuan-level low-grade elixir, how about a green gold plant?" The stall owner is a middle-aged man in his forties, and the price is basically realistic.

"Yes, but you have to tell me where these herbs come from." Ling Li said.

"It's nothing, this is something I found when I was packing up the relics of my ancestors, but unfortunately it has become invalid, or I would have acquired this Wanbao Tower a long time ago." The middle-aged stall owner showed a hint of pride on his face, "The ancestor of the family was once a disciple of the Tianxuan Sect, and he had participated in the Northern Ice Fields training, and these things were probably brought out by his old man." I heard that these medicinal herbs are the most common things in it, and it may be that the ancestor put them in a box on the bookshelf in order to keep a memory, and later even forgot about himself. ”

"Something from the Northern Ice Fields?"

"It should be, that's what the appraiser of Wanbaolou said."

Ling Li's pupils contracted, so that fragment should also be brought out of the Northern Ice Field, what kind of place is that inaccessible area?!

His eyes deliberately searched the stall several times before he grabbed the fragment in his hand: "How much does this thing sell for?" ”

"This material should not be ordinary, you can give 20,000." The stall owner didn't have a lion's big mouth, he saw that Ling Li liked it, but he increased the price slightly.

"Hmm." Ling Li nodded, he felt that this thing should be worth a lot of money, and he casually bought more than a dozen elixirs from the Northland, spending a total of more than 30,000 yuan, and then put everything away.
