At that moment, Han Rubing found a pen and paper and urged Ye Fan to write a letter of guarantee.

Ye Fan has never written a guarantee letter since he was a child, and he doesn't know how to write it.

In the end, it can only be dictated by Han Rubing and written by Ye Fan.

"Within three years, I, Ye Fan, promise not to mess with flowers and grass, and not to have deep contacts with any of the opposite sex, if I can't do it...... Swing a knife from the palace. ”

"Guarantor, Ye Fan. ”

Ye Fan heard the words waving his knife from the palace, and he didn't feel a little creepy, when these words came out of Han Rubing's mouth, he didn't feel like that.

Seeing Ye Fan's hesitation, Han Rubing glared at Ye Fan fiercely and asked, "Do you write?"

"Write. Ye Fan looked like he had surrendered, obediently wrote this guarantee, and signed his name.

Han Rubing accepted this guarantee as if she had obtained a treasure.

In fact, she is just seeking self-comfort, and this guarantee is just a cover for deceiving herself.

In the end, the conversation was quite satisfactory, and the relationship between them also eased indirectly.

After a pause, I heard Ye Fan say, "You go back to the house and sleep first, I'll go outside to cultivate." ”

"Isn't it good to cultivate outside at home?" asked Han Rubing strangely.

"It's not. Ye Fan came to prevent Han Rubing from thinking too much, and couldn't help but say, "You come with me." ”

With that, Ye Fan walked towards the sun room in the courtyard.

Han Rubing was stunned and followed with a new look.

Ye Fan turned on the sun room, and then turned on the heater in the cistern.

The current heater is not the fast heat used by Ye Fan at the beginning, but a medium-sized heater, which is generally used in high-end bathrooms in the city.

The temperature of the jade spring water itself was not low, reaching fifty or sixty degrees, and as soon as Han Rubing walked in, he was fascinated.

She also noticed the sun room in the courtyard before, which was foggy all day long, and she didn't know what was going on, but she didn't expect it to be a hot spring pool.

"Is this for bathing?" Han Rubing couldn't help but ask.

"This is not for bathing, but for domestic water. Ye Fan explained.

"Oh. Han Rubing was slightly disappointed, thinking that she could take a bath here.

Soon, the heater heated the temperature in the cistern to seventy degrees, and the aura in the cistern began to evaporate.

At this time, I saw Ye Fan casually holding a few wisps of aura.

The aura was green in Ye Fan's hands, and it looked very smart and magical.

"What is this?" Han Rubing asked curiously.

"This is the aura required for cultivation, the aura exists in every corner of heaven and earth, but the aura in the outside world is very thin, especially in cities, it is almost minimal. However, this jade spring contains a large amount of spiritual energy, and cultivating here will get twice the result with half the effort. A night's rest is worth ten days of cultivation outside. Ye Fan explained.

Hearing this, Han Rubing suddenly realized, so it was, and thought that Ye Fan was deliberately avoiding himself and wanted to go outside to cultivate.

"Now you know why I'm cultivating outside, right?" Ye Fan said.

"Understood, then do you want to cultivate here often in the future?" Han Rubing asked.

Ye Fan shook his head and said, "Although the aura content of the jade spring water is good, I don't know how many times it is richer than the outside world, but it is still impossible to break through to the foundation building with this. According to my estimates, after I reach the third level of Qi training, or the fourth level of Qi training, if I want to break through again, the spiritual energy required will increase by a hundredfold or a thousand times, and this bit of spiritual energy in Yuquan Water is obviously not enough. ”

"That's why you're going to the Hidden Gate?" Han Rubing asked.

"Hmm. Ye Fan nodded, and then said: "The Hidden Gate is the last base for immortal cultivators on the earth, and there is a strong aura in it, a large number of herbs, as well as spirit stones, spirit beasts, etc., these are all things that immortal cultivators dream of. ”

Hearing this, Han Rubing nodded and said understandingly: "Then you go, but you must pay attention to safety, don't be reluctant to do things that you are not sure of, even if you don't think about yourself, you have to think about your sister, if something happens to you, it will really be weak." ”

Ye Fan was stunned, then nodded, and said, "I know, I will be careful." In the hidden gate, I also have an uncle, who is my father's sworn brother, and he will be fine. ”

"That's good. Han Rubing then breathed a sigh of relief.

Actually, what Ye Fan didn't say was that he still had a mortal enemy in the Hidden Gate, the Blood Demon Sect.

If the Blood Demon Sect knew Ye Fan's whereabouts, he would definitely not let Ye Fan go easily.

In order not to let Han Rubing worry about himself, of course Ye Fan would not say.

"Come, absorb these aura. Ye Fan said.

"Can I absorb it too?" Han Rubing was surprised for a while, she thought that only immortal cultivators could.

"Why not? Reiki is very nourishing for ordinary people, has the effect of delaying aging and prolonging life, and at a young age like you, it can also maintain the elasticity of the skin. Ye Fan said.

"Really?" asked Han Rubing with a look of novelty in the blink of his eyes.

"Well, you'll find out if you try. Ye Fan said.

Immediately, Han Rubing took a deep breath and inhaled the aura gathered in the palm of Ye Fan's hand into his body.

Suddenly, Han Rubing only felt refreshed and indescribably comfortable.

"Here, absorb some more. Ye Fan casually held a few wisps of aura in his hand and let Han Rubing absorb it.

Han Rubing was not polite, and directly inhaled these spiritual qi into his body.

"Such a magical aura, I feel like my whole body, all my internal organs are baptized. Han Rubing said with a look of surprise.

"When I go back, I will ask Lu Daying to send some spiritual energy canisters to Nancheng, and you can absorb some every day in the future. However, don't be greedy, too much will overflow and will hurt your body. Ye Fan reminded.

"I know. Han Rubing replied sweetly.

"Okay, you go back to the house and rest, I'm ready to retreat, and I'll rush back to Jinling tomorrow. Ye Fan said.

"Good. Han Rubing responded obediently, although he really wanted to be by Ye Fan's side, but it had been agreed before, and it would not affect his cultivation.

Subsequently, Han Rubing went back to the house first.

Ye Fan sat down in the sun room, and now that the aura in the sun room was very sufficient, Ye Fan took two deep breaths and began to cultivate.

Han Rubing was reluctant to return to the room, the tense heartstrings during this time were finally released, and he was nourished by the aura just now, so he slept very soundly.

Before you know it, the night has passed.

The true element in Ye Fan's body has increased, but it is also extremely limited, and it is still very early to break through the third layer of qi training.

In the early morning, the sun shone on the earth, Ye Fan woke up from the retreat, and Han Rubing also woke up from his sleep.

Pushing open the door, the two looked at each other, and Ye Fan was the first to react, "Early." ”

"You're early, too. Han Rubing responded sweetly.

"Let's go, go to the town to have a bite to eat, and get ready to go back to Jinling. Ye Fan said.

"Hmm. Han Rubing responded, and then said: "Ye Fan, our sister is not in good health, that aura should help her, right? Do you want us to find a way to bring some aura back to Jinling?"
