"You really have a good kidney!" said the old man with a sigh.

"Eh?" Ye Fan was speechless for a while.

The old man continued: "The affinity of the aura to dissolve in water is very small, if you heat it slightly, the aura in the spring water will automatically run out. ”

"Is that so?" Ye Fan was stunned, and then reminded: "The temperature of the spring water is not low, fifty or sixty degrees. ”

"It's not enough, about seventy degrees. The old man said.

"Understood!" Ye Fan looked clear.

"Next time you have an accident, use your brains, don't do anything, you have a good kidney!" said the old man.

"Got it. Ye Fan responded.

Then, the old man couldn't help but fall into a deep sleep.

"How do you heat the spring water?" Ye Fan said to himself.

It seems impractical to fill a kettle with spring water and heat it on a stove.

Because the efficiency is too low, the water will have to be changed after a while.

"It's best to be able to heat it directly in the cistern. Ye Fan thought secretly.

Suddenly, an artifact popped up in Ye Fan's mind, a necessary artifact in the college student dormitory, it heats up quickly!

Yes, it heats up fast.

Paired with a water bottle, it's definitely the best companion for winter!

Immediately, Ye Fan ran to the store in the town and bought fifty in one go.

It's good to heat up quickly, but it's easy to break, and cultivation isn't a day or two, it takes a long time, so buy a little more, be prepared, and when it breaks, you can replace it with a new one.

After buying it, it was hot quickly, and Ye Fan bought a thermometer and a few plug-in boards, because there was no power supply on the side of the reservoir, and the electricity needed to be drawn out from the house.

After purchasing the required items, Ye Fan returned to the small courtyard.

After coming back, Ye Fan began the vast immortal cultivation project.

Several drag wire boards were connected in series, directing the electricity in the house to the edge of the reservoir, and then Ye Fan put down the immortal cultivation artifact and it heated up quickly, there were eleven or twelve, and he circled the reservoir a whole way.

Next, put down the thermometer.

The outside temperature was already below zero, and when it was put into the reservoir, the temperature soared, and after a while, it soared to fifty-two degrees.

Seventy degrees away, still some distance.

Ye Fan was not in a hurry, and waited slowly.

I just waited for more than ten minutes, and I didn't see the temperature rise, but it just rose by one or two degrees.

"This is too slow, isn't it?, what about the heating artifact?" Ye Fan was depressed for a while.

The efficiency of a dozen or so hot and fast heating is actually not low, but this reservoir is really not small, there are two or three tons of water in it, so it is inevitably difficult to heat, like a small horse-drawn cart.

"It seems that you can only add some more heat quickly!" Ye Fan said secretly.

Subsequently, Ye Fan found a few sticks more than one meter long and built a simple shelf, which could just be covered on the cistern, and the shelf was tied to heat quickly, so that not only the edge of the cistern was heated, but also the middle was heated together.

It took about twenty more to heat up quickly, and the temperature of the reservoir changed significantly, and it climbed up rapidly.

"Fifty-five degrees...... Fifty-seven degrees ......"

In less than a quarter of an hour, it had risen to 60 degrees, and it continued to rise.

"Sixty-two degrees...... Sixty-five degrees ......"

When the temperature of the reservoir rises to sixty-five degrees, the aura in the spring water begins to become agitated, and it continues to evaporate from the spring water.

It is worthy of an artifact, and the heating efficiency is high!

Large swaths of spiritual energy evaporated, like a cloud of white mist, suspended above the reservoir.

Ye Fan took a deep breath, and the white aura entered his mouth, and he was immediately refreshed.

However, Ye Fan did not immediately start his retreat and cultivation, but adjusted the water inlet and outlet valves.

If the water in the reservoir does not flow, the aura in the spring will be steamed up sooner or later, and only when there is a steady stream of new spring water can the aura be maintained.

After adjusting the inlet and outlet valves to an appropriate degree and keeping the temperature in the reservoir at about seventy degrees, Ye Fan secretly breathed a sigh of relief and prepared to retreat.

Fortunately, in addition to the automatic opening and closing of the inlet and outlet valves, there is also a manual mode, otherwise it would be a bit troublesome.

"Everything is ready, you can start!" Ye Fan said secretly.

Immediately, Ye Fan finished his plate and began to retreat.

However, at this moment, a cold wind blew, and the dense aura gathered above the reservoir was directly blown away.

"My aura. Ye Fan was depressed for a while, "Damn the cold wind!"

Helpless, Ye Fan could only find some wooden planks and make a fence around the reservoir to block the wind, but fortunately there was a screen in the house, which could come in handy.

After all this was ready, Ye Fan was just about to retreat when there was a sudden knock on the door of the small courtyard.

"Who?" Ye Fan frowned for a while, looking very unhappy.

"Mr. Ye, I'm Lu Jianglong, the dinner is ready, and my father asked me to invite you over. Lu Jianglong's voice came from outside the door.

Ye Fan paused, although he didn't really want to go to the banquet, the dinner party was more attractive than these aura, but he also knew that this was Lu Haidiao's heart, and he also had to live in the Lu family's courtyard for a while, so he couldn't help but say: "Okay, I know, I'll come." ”

Later, Ye Fan tidied up his clothes and left the small courtyard.

"Mr. Ye, are you still used to living in this small courtyard, is there anything else you need to add?" Lu Jianglong asked respectfully.

"No, everything is fine. Ye Fan said.

"Then arrange a young nanny for Mr. Ye to take care of Mr. Ye's daily life. Lu Jianglong said.

Nanny?

The key is to be young!

The Lu family thought about it.

I heard Ye Fan say: "There is no need for this, I want to retreat before the Yuquan Festival, and no one should disturb me." ”

"Understood, understood. Lu Jianglong replied again and again.

During the conversation, he had already come to the Lu family compound next to him.

Lu Haidiao had been waiting at the door for a long time, and when he saw Ye Fan entering the door, he hurriedly greeted him, "Mr. Ye, please inside, today I specially asked the best chef in the town to prepare a table of whole sheep banquet." ”

"The carving master has a heart. Ye Fan said.

"It should be, it should be. Lu Haidiao replied again and again.

"By the way, Master Diao, when the Yuquan Festival is over, I may have to stay in your mansion for a while. Ye Fan said.

"Mr. Ye, you are too outward, we can live as long as you want in the Lu family. Lu Haidiao said.

"Okay, then bother. Ye Fan said.

"Don't bother, don't bother. Lu Haidiao said, and then invited Ye Fan to take a seat.

Naturally, he sat in the guest of honor seat, and Ye Fan did not shirk.

At this time, I heard Lu Daying report in a low voice: "Mr. Ye, the things you explained in the morning have been dealt with." ”

Hearing this, Ye Fan was slightly stunned, and then thought of something, referring to Zhao Jing's matter, and couldn't help asking: "After the matter is dealt with, she should leave, right?"

"I don't think I'm leaving. Lu Daying replied.

"Didn't leave?" Ye Fan shook his head for a while, "It's really a stubborn girl, it seems that she won't leave if she doesn't interview some dry goods from the Yuquan Festival." ”

Ye Fan didn't say any more, Zhao Jing can stay if she wants, this is her freedom.
