The magic pillar was already close at hand, and Tang Lin's hand had already stretched out, but before he could touch the magic pillar, the Rubik's cube at the top of the pillar spun rapidly, directly hit his hand, and then shattered into regular small squares.

"I'll go, touch porcelain?"

Tang Lin was startled, and before he could react, the spirit ball in his mind began to riot, directly releasing an extremely violent energy, surging along the meridians of his arm to the palm of his hand.

After enduring a period of bone-chilling pain, Tang Lin stared at the handful of colorful small squares in his hand.

At this moment, they slowly sank into the palm of their hands like stones that had been thrown onto the surface of the silt.

That's right, it was in the palm of his hand, and before he could continue his research, there was another tearing pain in his arm, almost making him faint.

After the pain dissipated a little, his consciousness entered the depths of his brain on his own, only to find that the little Rubik's Cube was already there, and it was still well recovered, and it was constantly rotating around the spirit ball, and it was also spinning itself.

"What kind of trouble are you going to make, what is the purpose of this thing? Tang Lin was no longer surprised, he just wanted to find out what benefits he could get from suffering such a sin, and in the end, what benefits he could get!

"Start transmitting some of the knowledge of magic potion and magic casting to the Lord of Civilization!" A message appeared after Tang Lin's consciousness touched the Rubik's Cube, and the next moment, a corner of the Rubik's Cube lit up, followed by a massive amount of information pouring into Tang Lin's consciousness.

"If I go, can't I be gentle, it's too irritable!" Tang Lin was dizzy, and he spat out fiercely in his heart, but then there was a huge surprise, because he once again opened a door, a door to knowledge, and at the same time a golden road to wealth.

"Potions, this is something that everyone is eager for, whether it is ordinary people, or cultivators, whether it is the nobles of the empire or ordinary people, they can't resist its temptation!

This was the conclusion that Tang Lin came to after browsing a part of the knowledge, and this conclusion made him hungry and thirsty to start the learning mode.

"Alas, if you want to make money, you still have to have the capital first!" A night of study gave Tang Lin a deeper understanding of the dignity and "nobility" of magicians.

Right now, all he received was Potions Knowledge and Magic Casting Methods from Level 1 to Level 3, but there were many recipes where the ingredients were already ridiculously expensive, not to mention those from Level 9 onwards.

"Everything is difficult at the beginning, and you can't rush it, so start from the basics, and let Anne and the green demon open up a medicine field in the manor later, and then go to the Black Forest to get some medicine seedlings!"

Tang Lin felt that it was time to transform labor into productivity, otherwise his potions knowledge might not be able to be realized, thinking of this, he opened his eyes.

"Well, you've finally woken up, you don't see it, you're still a big lazy worm!" Irina's good-looking face suddenly appeared in front of Tang Lin's eyes, and he stood up immediately.

"I didn't sleep, I was studying, that Rubik's Cube stores some knowledge of melting magic items and refining synthetic potions, I hope this laboratory can be used quickly, we are very poor now, so we have invested in learning!"

Tang Lin rubbed Irina's head, casually cast a life magic, turned the life energy into a marshmallow and handed it to her, suddenly frowned, remembering the function of a special magic item in the melting technique.

"Tang Lin, do we really have no money? Otherwise, let's go and let Sha Ming dig out the three underground floors, there is really a treasure trove there, I won't lie to you!"

Irina muttered as she nibbled on the most expensive "marshmallow" on the continent, and as a princess, he didn't know what it was like to be short of money.

Tang Lin was interrupted to think, but he didn't care at all, although it was a bit whimsical for Irina to ask Sha Ming to dig out the entire underground three layers of the castle, but it was still feasible to dig a passage to the portal to the third underground floor.

Now Tang Lin has a chance to open the treasure house, he was annoyed for a while because he didn't find the door, and now the problem is solved.

"Irina, you're so smart!" Tang Lin smiled and grabbed the other party's hand, and directly pulled him to find Sha Ming.

After this black girl came to the manor yesterday, she made a bunker near the edge of the paste, and really settled in the manor.

At this time, the sisters were cheerfully greeting old Luke, and the old fellow had gotten up early to get wild fruit for everyone.

After hastily ending the game breakfast, Tang Lin told Sha Ming his request, and the black girl immediately complied.

She told Tang Lin that when she was digging the bunker yesterday, she found that there was a very thick energy layer under the manor that directly protected the building of the third underground floor, and this energy layer only had a very regular gap, which should be the portal to the third underground floor!

"I knew it wasn't that simple, and if you wanted to enter the door, you still needed conditions!" Tang Lin shook his head helplessly and took out his golden key.

"Let's go, let's dig a hole!" Tang Lin was embarrassed to let Sha Ming, the little girl, do it alone, so he asked Old Luke to get a tool, this tool should be able to dig earth and stone quickly with the blessing of Tang Lin's earth magic!

"Brother Lin, what are you doing with a shovel, we desert cave people don't use tools!" Sha Ming was a little dumbfounded, looking at Tang Lin who was rolling up his sleeves there, a smile rose on the corner of his mouth.

"No tools, then I won't be able to help you, my mana isn't that strong yet, otherwise I'd have already done it!"

Tang Lin scratched his head, and then he was stunned by the scene in front of him, only to see that Sha Ming's arms suddenly began to dry up, and finally took on the appearance of a yellow sand sculpture.

Then she pressed her hands to the ground, and the surprise began, and the ground began to fall like quicksand, and a staircase that slanted down appeared little by little, as if it had been painted.

After two quarters of an hour, an underground passage with a drop of more than three meters was built, Sha Ming sat directly on the ground, it seemed that the consumption was quite serious, Tang Lin asked Hai Yun'er to take care of her, and asked Anne to take the green demon to work on the medicine field, and he took Irina down to the passage.

At the end of the passage was a door, standing in front of the door, the key in Tang Lin's hand became more and more brilliant, and there was a feeling that he was going to leave.

Without too much hesitation, he opened the door directly, and after pushing the door in, he didn't find any golden treasures, and the whole space was clearly displayed in front of the two of them under the illumination of the magic lamp.

This space is not large, there is a diagonal downward passage in front of it, and then there is a gate with chains on each side, which is eerie and a little scary, and it is obviously not a treasure room.

According to Irina, the underground treasure house is on the lowest floor, which is the minus three floors, and their current location is only the minus layer.

"I guess this door will electrify me!" Tang Lin smiled, although he said so, he couldn't control his hand, and when the words fell, he put his hand on the chain.

"Crack!" The sound of the arc hitting Tang Lin was very loud in this not too large space, this time, Tang Lin's arm was directly scorched, and the green energy gushing out of the spirit bead was also unprecedentedly rich.

"Why are you so cheap, your hands are itchy?" Irina rolled her eyes, but she was also shocked in her heart, because this completely subverted her previous memory of this place, and it can be said that the current underground three floors are completely different from what she remembered before, and have been completely transformed.

"Let's go, keep going!" Tang Lin once again used the life magic marshmallow offensive and blocked the cute girl's mouth.

The negative second floor will soon arrive, and the situation on the negative floor is similar, here are also two doors and a passage, but the breath on the door is very comfortable.

Tang Lin was still cheap, and the very comfortable feeling made him uncomfortable in an instant, and he harvested two scorched arms.

However, this time, the spirit bead did not treat him immediately, it looked like a power bank that needed to be stored, of course, it may also be to warn him not to be so curious!

It wasn't until he stopped for a long time and began to walk into the passage of the negative third floor that the spirit bead covered his arm with thin repair energy.

"It's here, it's different when you look at this door!" Tang Lin stood here on the third floor, looking at this and that only gate, his heart was also excited, and he secretly sighed that it was a big deal.

There's only one door here, and it's really just a matter of looking at the door to know that you've found your destination this time.
