Lin Xi knew that Xi Bingxuan definitely didn't want anything like gold and silver, so he asked so.

But if the other party wants something too much, and she can't take it, then forget it.

It's a big deal to sell the formula when the time comes, otherwise let Feng Yi find someone to study it himself.

"Just kidding, you are still serious, not to mention the development of the mortal world, I will not be able to pay off the potions you gave me. Xi Bingxuan said.

It's just some medicine, where can it compare to Lin Xi's favor.

"The amount I want may be a bit large, so you should put forward the conditions. Lin Xi shook his head and refused.

"How big?" Xi Bingxuan disagreed.

"It's uncertain how many there are, at least tens of thousands, and there's no upper limit. Lin Xi said.

Xi Bingxuan was silent, so many words really can't be given in vain.

Because they didn't think about what to exchange for, Lin Xi and Xi Bingxuan both pondered.

At this time, Ah Jiu ran over and asked breathlessly, "Miss Lin, are you ...... Do you still have the green crystals you gave?"

"What's wrong?" Lin Xi asked suspiciously.

Of course, the heart of the tree still has, but she wants to know what Ah Jiu has researched?

The heart of the tree that Lin Xi gave to Ah Jiu was the smallest, and the largest was the heart of the peach tree, which was also the oldest.

Speaking of this, Lin Xi has to find the heart of the Dripping Heart Tree.

"This thing can increase the awakening rate of the awakening talent, and there will be no more pain and injury if the awakening fails. Miss Lin, how many more green crystals do you have?" Ah Jiu immediately said the matter.

Lin Xi was surprised, thinking that the system's awakening elixir wouldn't have this ingredient in it, right?

"This thing is relatively rare, how many of these potions can I make for your tree heart?" Lin Xi asked, if the amount needed was very large, then she would not be able to do it.

"There are a lot of potions, because the crystals are very pure, and only one drop of diluted potions can have an effect. It's so big, you can make thousands of bottles of potion. Ah Jiu estimated and said.

Lin Xi looked at Xi Bingxuan and said, "It seems that I know what I can exchange for potions." ”

Xi Bingxuan nodded helplessly in agreement.

Then Lin Xi took a few more tree hearts to Ah Jiu, Ah Jiu was in a hurry to go back to study, and Lin Xi and Xi Bingxuan were waiting for dinner.

"What strength are you now? It doesn't seem like there is any change in your appearance. Xi Bingxuan asked Lin Xi.

"Of course I haven't changed, it's only been a few months. It's you, decades have passed, and you don't seem to have changed much. "Compared to Lin Xu, Xi Bingxuan is too young.

"After breaking through the fifth order some time ago, I have rejuvenated. Xi Bingxuan said with a smile.

"Decades have passed, and you are only the fifth order?" Lin Xi's disgusted tone made the smile on the corner of Xi Bingxuan's mouth freeze.

"Do you think talent is so easy to improve?" said Xi Bingxuan.

"Is it difficult? It's only been more than a year since I awakened, Fourth Order. Lin Xi said.

Xi Bingxuan suddenly didn't want to speak, people are more popular than people.

"Let's talk about cooperation, how do you solve the problem of time difference?" asked Xi Bingxuan.

"Big deal, I'll come once a day. Lin Xi said, it's okay to pick one or two disappears every day.

In this case, the supply of tree hearts should not be able to keep up, which is a big problem.

I don't know if I can use it instead, after all, the heart of the tree is also a part of the Dryad.

If it could be replaced, the dryad would be much cheaper than the heart of the tree.

There seems to be a dryad in her space device that has not been sold, so let Ah Jiu try it when the time comes.

The dinner between the two was very rich, and Lin Xi disliked Xi Bingxuan's extravagance while eating happily.

Xi Bingxuan was too lazy to bother with Lin Xi, after all, he could be Lin Xi's grandfather in terms of age.

After Lin Xi finished eating, he went to find Ah Jiu, gave him the tree demon, and then saw if he could replace the effect of the tree heart.

Lin Mansion, Lin Ri excitedly said that she must have inherited her aunt's talent.

Lin Xu knew that it was not, but inherited his mother's talent, because Ruan Tian was a wood talent, and besides, he and Lin Xi were not related by blood, so he inherited the fart.

No matter what, it's always good to awaken your talent, and if you awaken the same talent as Lin Xi, you can also ask Lin Xi how to cultivate.

After Lin Xi learned that Lin Ri had awakened the wood-based ability, he gave him a few wood-based skills and asked him to study them well.

Lin Rishi took it stupidly, but Lin Xu patted him on the head and asked him to say thank you, not polite.

The next day, Lin Xi went to King Ning's Mansion early in the morning.

Xi Bingxuan had already prepared 50,000 awakening potions and 5,000 antidote potions.

Lin Xi gave him ten repair potions and asked them to do research.

Ah Jiu got the result there, and the liquid refined by the dryad can replace the effect of the tree heart, but it is still not as good as the tree heart.

As long as it works, it's fine.

After the things were in hand, Lin Xi was ready to go back.

I thought that she had been in Qingqiong for a day, and it might only be an hour and a half after she went back, but I didn't expect that a day had passed since she went back.

Time turned out to be synchronized, so what happened before?

If this world is synchronized with Qingqiong, then what is going on with Qingqiong for decades? It can't be because it takes a few days to go to Zhao Xingqi's food world?

That's not right, this world has passed ten years, and Zhao Xingqi has passed a few days, and Qingqiong has been for decades.

It's too messy.

For this, the system says that it is also inaccurate, that time changes all the time, and there is no law at all.

Either way, it's good that the time difference between the two sides is the same, so she doesn't have to run that way every day.

When Lin Xi came back, Feng Yi was sitting in the living room and didn't know what to think?

"Why are you at home at this time?" Lin Xi asked.

Feng Yi raised his head violently when he heard the voice, and immediately stepped over when he saw Lin Xi, then held the person in his arms, buried his head in her neck and took a deep breath.

"Didn't you say you'd be back soon?" Feng Yi said in an aggrieved tone.

Lin Xi stiffened, then quickly relaxed his body and said, "The estimation is wrong, it won't be next time." ”

"Hmm. Why don't we do this business?" Feng Yi said in a sullen tone.

"What's wrong?" Lin Xi pushed the person away slightly.

"I ...... Afraid, across time and space, too far away for me, I'm worried. Feng Yi did not hide his emotions at all.

Lin Xi was silent, she was used to coming and going across time and space, and she had long ignored the danger.

"Okay?" Feng Yi asked cautiously.

If it had been before, he might not have been like this, but seeing Lin Xi disappear in front of him with his own eyes and not coming back at the promised time, he was very nervous about the day.

At this time, he knew how important Lin Xi was in his heart, and how much he was afraid of losing Lin Xi, even if he didn't recover his memory, he still knew how important Lin Xi was in his heart.
