When he was halfway there, Su Mu's mobile phone rang, and it was a video call application from the drum.

It is rare for the drum to take the initiative to send a video, there is no one left and right, Su Mu pressed the answer button, and saw the big face of the drum appear on the screen.

"What's the matter with the video?" asked Su Mu.

"The three divine items [Lord of Shadow Stream], [Ghost Mother Bone Bead], and [Maggot Gu], I have completed the second cleaning to ensure that they are clean, and there will be no more hand tails left. Hurry up and take out the gourd, and I'll send it to you. ”

At this, the drum sighed faintly, and then complained.

"In order not to go wrong, when I purified these three divine objects, I didn't drink a single sip of wine. It's been hours, but it's suffocating me!, and you take the things away, so that I don't have to drink in peace, lest anything go wrong if I accidentally get into trouble......"

Su Mu laughed dumbly, and finally understood why the drum was so active-it was all caused by the wine worm in his stomach.

It was indeed quite not easy for him to endure for several hours without drinking and complete the careful purification of the three divine items.

"Wait a minute. ”

Su Mu said and looked around, the route he flew was not affected by the morning rush hour, and there were no people up and down, left and right.

Even so, he first put a trick to prevent people from seeing him, and then he took out a gourd with an eye pattern and said to the drum, "You can teleport here." ”

The eye pattern on the gourd immediately spun.

Only three soft sounds of 'Bo Bo Bo' were heard, and the [Lord of the Shadow Stream], the [Ghost Mother Bone Bead] and the [Maggot Gu] all jumped out of the gourd and were pocketed by Su Mu.

"Okay, let's settle the matter this time, and I won't delay you from drinking, bye-bye." ”

Su Mu said that he was going to turn off the video.

"Wait, there's one more thing. The drum hurriedly stopped him and asked, "Do you want the cultivation method of the Pure Spirit Grass?"

Su Mu was stunned when he heard this: "You still plant Pure Spirit Grass?"

No wonder he was surprised, the Pure Spirit Grass was a special new spirit plant that Yuan Lao and his team had only researched and cultivated in recent decades.

It is said that such an 'old antique' as the drum should not be able to know this new knowledge.

Could it be that among the cultivators he devoured before, there were experts and professors in the Spirit Plant Department who were engaged in this kind of research?

But listening to the drum explained: "During this time, there have always been people planting this green spirit grass in the ice above my head, and I have watched them cast spells every day and learned some skills. ”

Speaking of this, Gu saw that Su Mu frowned and was silent, thinking that he was not interested in this knowledge, and was a little anxious: "If you want to learn, I will sell you cheaply, it is really cheap......"

The idea of the drum is very simple, this knowledge is considered to be picked up by him for nothing, and he can exchange it for money and wine, no matter how much, it is earned, and it can also alleviate the embarrassing situation of selling blood and even dragon scales......

He didn't dare to sell this knowledge too expensive.

I'm afraid that if Su Mu is expensive, or if you go to a teacher who specializes in spiritual plants to learn, won't you be able to earn a penny?

Seeing that Su Mu was still silent, the drum added: "I know that the cultivation skills of the Pure Spirit Grass should be taught by a teacher in your school. But they don't teach the same thing as I do. In the knowledge I have collated, my views and understandings have been incorporated. It's called celebrity annotation, and it's very memorable. ”

What Gu didn't expect was that Su Mu was actually very interested in the Pure Spirit Grass.

Although Su Mu is not a spiritual plant professional, he knows the importance of pure spiritual grass.

If there is no Pure Spirit Grass, the spiritual energy in the world will deteriorate rapidly due to pollution.

When the time comes, let alone cultivation, if you inhale a little deteriorating aura, you will have the possibility of going mad and going crazy.

With the third secret realm coming soon, many scholars also believe that the Pure Spirit Grass will also come in handy in this event.

According to historical records, the first two secret realms came, and the secret realms when they first appeared, were like desperate and fierce places, and the aura was violent and chaotic.

In that kind of environment, let alone cultivating, if you stay for a little longer, you will be affected, and you will become violent and murderous!

Therefore, we must find a way to purify the violent and chaotic aura in the secret realm.

This is also the key project of the research of the spirit plant experts all over the world in the recent period: how to make the pure spirit grass survive and work effectively in various extremely harsh environments.

Su Mu wanted to learn the cultivation technique of the Pure Spirit Grass, but it was not anyone, he had to plant the Pure Spirit Grass.

He didn't have that time, he didn't have that energy.

What he wants to do is to upgrade the cultivation technology of the Pure Spirit Grass to perfection through the krypton gold plug-in, and even make a breakthrough, so that the Pure Spirit Grass can adapt to and improve the aura in the desperate land faster and better.

In this way, it will certainly be a great achievement! Not only for the benefit of the present generation, but also for the future generations! Even if you can't get into a Chinese textbook, you can still occupy a position as an examination center in a history textbook.

In order to make himself a nightmare for thousands of candidates, Su Mu felt that this knowledge should be learned and must be learned!

But he can't let the drum see what he really thinks, otherwise this despicable and shameless fat house dragon god will definitely ask for a sky-high price.

So Su Mu said in a very helpless tone: "I'm not a spiritual plant major, what are you doing to learn this knowledge?"

When the drum heard this, he didn't doubt it at all, and hurriedly persuaded: "As the saying goes, you don't have to press your body if you have more skills, I sell it cheaply, and you won't lose money if you buy it." Wouldn't it be nice if you got a girlfriend who was a spiritual plant professional, and you could show it in front of her?"

"Kind of makes sense. Well, for the sake of your dedication to helping me purify the three divine items this time, although this knowledge is of little use to me, I will buy it too. ”

Su Mu had an expression of 'I am willing to buy this knowledge because you performed well and gave you an encouragement'.

Gu was convinced, and even said thank you, for fear that Su Mu would regret it, so he immediately sorted out the cultivation technology of the Pure Spirit Grass into a document and sent it to him, and also said that the wine exchanged was not in a hurry, it was on the account, and it was okay to give it later.

This operation made the book spirit who had been following Su Mu stunned and trembling when he saw it.

It is said that a man's mouth is a deceitful ghost......

Even the gods dared to deceive, but the gods were still very happy and said thank you to him...... This mouth of his is simply terrifying.

Maybe one day this god will be sold by him, and he will have to help him count the money!

Eh, wait! A question suddenly flashed through the scholar's mind: we can't be deceived by him, that's why we work for him so desperately, right?!

This made Shujing shudder.

"What's wrong, isn't it feeling well?"

After receiving the document, Su Mu hung up the video call with the drum, noticed the abnormality of the book spirit, and thought that it was frightened by the drum, or suppressed by the blood.

In a good mood, he took out a Peiling Pill and threw it to Shu Jing: "Take a pill and suppress the shock." ”

When Shujing saw Pei Lingdan, his eyes on the cover suddenly lit up, and he jumped high like a dog, and a big mouth cracked out on the cover, and he swallowed Pei Lingdan into his mouth with a 'whoosh'.

The book spirit who ate the pill looked satisfied, and what he thought in his heart became: As long as there is often the pill to eat, there are leftovers for me to solve every day, even if I am deceived and deceived for a lifetime, I am happy.

Su Mu didn't open the document in a hurry, and was going to use the gap between cultivation and study to see that there were other things to be busy with now.

He quickly flew to the edge of the Krypton Shop Factory.

After the expansion, the factory is quite large-scale, and finally has a bit of a well-known factory, but the number of students staying outside is much smaller than before.

One is that the freshness has passed, and the other is that there is an illusion circle in the factory, so that people can't see anything from the outside, and naturally no one is willing to come here to waste time.

Even so, Su Mu remained cautious.

He landed in a deserted jungle, first using illusion to change his appearance, and then he used the earth escape technique, and escaped into the krypton shop factory with the book spirit.

The security captain Ku Zhu found out about his arrival for the first time. After confirming the identity, he hurriedly notified Ouyang and Tu Shansong.

When Su Mu escaped from the ground, Ouyang, who was holding a toad's belly, and Tu Shansong, who was smiling, had already led a group of employees to come out to welcome them.

Seeing this scene, Su Mu was also very emotional.

I think that at the beginning, when the Krypton shop factory was just opened, in addition to a group of rune figures, there were only two employees, Ouyang and Kuzhu, which are like now, there are dozens or hundreds of employees, and they are all cultivators and spirits!

Who can compare with this lineup?

Listening to the employees chanting 'Hello boss', the sense of accomplishment in Su Mu's heart was called a foot.

"Hello everyone, everyone, for a great work. Su Mu waved his hand at everyone, and then said to Ouyang and Tu Shansong: "Let's stop standing and talking here, let's go to the conference room, I also want to know about everyone's recent work." ”

"Okay, okay, boss, please come with me. ”

Ouyang and Tu Shansong hurriedly nodded and led the way.

On the way to the conference room, Su Mu asked about the production of the potion.

The spirit plant department was in a hurry, and on the way to the factory just now, I called him to ask.

Ouyang reported: "Ma Han, Wentai and other equipment repairers, last night overtime, according to the plan you gave, the production line has been transformed, from five o'clock this morning, officially put into production, has produced a batch of medicines ......"

Su Mu instructed, "Contact the teacher of the Spirit Plant Department immediately and ask them to come and pick up the goods." ”

"Yes!" Ouyang replied, and then said, "We had a meeting last night. It was agreed that the demand for this agent would be very high for a long time to come. With our own production line, we can't keep it busy. Do you want the school to come forward and help find a few reliable pharmaceutical foundries, or buy them directly?"

Su Mu thought about it for a moment and said, "Your suggestion is not unreasonable, I will talk to Principal Wen." ”

Speaking of this, he suddenly thought of something.

Could this rusty monster that disturbed all spirit plants go to the Pure Spirit Grass from the beginning?

If that's the case, then the problem is quite serious!
