"Xiaoxing, what immortals were collected last time you collected rags, do you remember?"

In the Haotian Palace, Zhang Zichen was lying on the dragon bed in the dormitory and lazily asked the official on duty.

His whole person was so tired that he was about to fall apart, and although the great court meeting that had just dispersed was not a heavy physical work, it was not a small consumption of spirit and spirit.

"Your Majesty, in accordance with Your Majesty's orders, the ministers are recorded in this account book, please look at it. ”

As he spoke, the star officer on duty took out a book from his sleeve and respectfully handed it to Zhang Zichen's hand.

"They are the Laojun family, the Yuan Shi Tianzun family, the Tai Bai Xing family, and..."

The star officer on duty is indeed intimate and responsible, Zhang Zichen looked at the account book, and the star officer on duty explained on the side, he made it clear which immortal's house he received what objects.

"Okay, when I first collected the rags, I said that I would give them the objects of the world in return, and now it's time, let's go first, and then have a good rest when we come back.

Otherwise, I'm afraid that people will come to the door to ask for debts, and we will lose people again!"

Zhang Zichen said with some self-deprecation.

Dealing with these immortals is simply more tiring than in the human world, trivial things are more clear than in the human world, and obviously these things are just useless waste to them, but they can be used to blackmail him, the Jade Emperor, once.

Zhang Zichen became more and more suspicious of whether these immortals had colluded to stumble on him in order to complete the grinding that Lao Jun said.

...

"Laojun, open the door, the community is warm!"

Thirty-three days, Tushi Palace.

Zhang Zichen stood at the door of Lao Jun's house again and opened his mouth to call the doorway.

Unlike the previous times when he asked Lao Jun to fight the autumn wind, Zhang Zichen did not come this time to get things, but to send things.

"Haha, Your Majesty is here, it's a long way to go!"

As soon as Zhang Zichen shouted at the gate of Tushi Palace, he saw that the door of Tushi Palace was suddenly opened, Lao Jun smiled with a spring breeze on his face, holding a whisk in his hand, and the two children of the bright moon and breeze stood left and right.

"Oh, Your Majesty came to visit the palace because he can afford to look at my old man, and what kind of gifts do you bring. ”

Lao Jun saw the heavy storage bag that Zhang Zichen was carrying, and while smiling and humbling, he took the storage bag from Zhang Zichen's hand without a trace, and then threw it to Daotong Qingfeng to hold.

Zhang Zichen couldn't help but feel very admired for Lao Jun's hypocritical and unscrupulous behavior, although he said no, he was very honest in his hands.

"Your Majesty, please. ”

Lao Jun gave up, and then invited Zhang Zichen into the Tushi Palace.

The Tushi Palace is the same as the last time I came, there is no change, it is still the same aura, and the rich aura flows down the pores, soaking people's hearts.

Just like last time, the fragment of the Heart of the World in his body just wanted to swallow the aura, and was immediately given by Lao Jun's spell.

"Your Majesty doesn't pity the poor old man, if you let this guy start, my Tushi Palace will become the end of the world. ”

Lao Jun joked with a smile.

"Hmph, stingy, Lao Jun handed over the heart of the world to me, but he didn't give me aura, this is really asking the horse to run, and the horse not to eat grass. ”

Zhang Zichen was not to be outdone, and fought with Lao Jun.

"Haha, what good things did Your Majesty bring to the old man this time?"

Lao Jun is really old and spicy enough, and he changed the topic with a smile, which made Zhang Zichen quite depressed.

"Well, when I get to Lao Jun's Dan room, I will naturally know about it. ”

Zhang Zichen sold a pass rather mysteriously.

Lao Jun glanced at him with a smile, didn't ask any more, and took Zhang Zichen straight to the Dan room.

"Qingfeng, take out the contents of the bag. Try to keep them as far away from the furnace as possible. ”

After arriving in the Dan room, Zhang Zichen looked at the breeze holding the storage bag and said.

"Yes. ”

Qingfeng opened the mouth of the storage bag, recited a general storage spell, and took out all the items in the storage bag, and as soon as the contents of the bag came out of the storage bag, they immediately returned to their original size, and a large area was filled with a large area in the north of the Danfang.

"Your Majesty, what is this?"

Looking at the many metal cans that occupied most of the Dan room, Lao Jun asked with a smile.

Zhang Zichen didn't believe that Lao Jun couldn't figure out what this was, but Lao Jun pretended not to know that he couldn't do anything, so he had to explain depressedly:

"This is liquefied gas, which is the most commonly used fuel in the world today, it has high calorific value, no smoke and dust, no carbon slag, and it is very convenient to operate, which can continuously and stably provide high temperature open flame, which is the most suitable for Laojun alchemy.

With this thing, Lao Jun no longer needs to use the diamond coal, which is becoming more and more scarce in the fairy world, and he doesn't need Lao Jun to spend a lot of mana to maintain the burning of the three flavors of true fire, nor does he need to carefully fan the wind and light the fire and wait for the flames.

With this liquefied gas, Lao Jun's alchemy will be twice as effective with half the effort from now on, and the heat can also be adjusted through this liquefied gas stove I brought.

There is no need to painstakingly adjust the subtle heat, and there is no need to worry about bursting the furnace due to uneven temperature.

What do you think of this thing?"

Zhang Zichen was confident, he didn't believe that Lao Jun would not like this kind of good thing.

In order to let Lao Jun have a more intuitive feeling, Zhang Zichen personally practiced the operation, and told Lao Jun how to operate the liquefied gas stove.

"Wonderful!

After listening to Zhang Zichen's introduction, Lao Jun operated it himself, and couldn't help but brush his beard and praise.

Rao is Lao Jun had already calculated that this thing could be burned, but he was still frightened by the characteristics of liquefied gas.

"So Lao Jun is still satisfied, is this item enough to be worth the items that he took from Lao Jun before?"

Zhang Zichen's big face smiled into a chrysanthemum, and asked happily.

"This is naturally worth it, Your Majesty has a heart. ”

Lao Jun naturally has nothing to be dissatisfied with, what he paid is a useless dead object, and he didn't even think of letting Comrade Jade Emperor use things as collateral, it was all to support the toss of this new Jade Emperor, and now Zhang Zichen has brought him such a wonderful stable fire source, how can he not be surprised.

"This tank of liquefied gas is twenty kilograms, and it can continue to burn for about thirty to fifty hours in an ordinary household in the world, considering the large liquefied gas stove I customized for Lao Jun's alchemy furnace, in this way, one tank is probably enough for Lao Jun to use it for twenty-four hours in a row, that is, two whole days in the world.

There are a hundred jars of liquefied gas here, which is probably enough for Lao Jun to use the human world for about two hundred days, so that whether Lao Jun is refining forty-nine days or eighty-one days or even years of great pills, it is more than enough.

It's just that it needs to be noted that this liquefied gas will explode close to the fire source, and leakage will cause poisoning, but with Lao Jun's supernatural powers, these must not be a problem. ”

Zhang Zichen pushed the sales to the end and explained in detail.

"Your Majesty means that after these hundred cans of liquefied gas are used up, the minister still needs to ask Your Majesty for help, right?"

What a character Lao Jun is, although Zhang Zichen's careful thinking is vague, he can still easily hear it.

"This... Hehe, that's true, when these liquefied gases run out, Lao Jun can tell me again, how about buying one catty of liquefied gas for about a hundred catties of spiritual liquid?"
