There is no one else in this small world, and the owner of the voice can only be the Sword Master.

As soon as Wu Yu turned his head, he saw the Sword Saint standing not far behind him, his gaze falling on the Wang Pin medicinal herb in his hand.

I don't know if it's because the moonlight is too dark tonight, the Sword Master's face looks a little dark.

Wu Yu silently put the medicinal materials into the Empty Source Stone, and replied honestly: "I am testing the capacity of the Empty Source Stone. ”

The sword saint's eyelids jumped, and he was secretly glad that he rushed over after sensing the fluctuation of the power of space, otherwise he was afraid that most of the medicinal materials he had worked so hard to cultivate for many years would be taken away by this kid.

"Don't try it, the Empty Source Stone is what I refined with the Spatial Origin as the main material, and the space inside is extremely vast, as long as your Xuan Power is strong enough, you can even fit the entire main world where the Xuan Continent is located."

The Sword Saint changed his words and said in a concerned tone: "Although the injuries in your body have healed, the discomfort caused by mental overdraft will not subside in a while. ”

Wu Yu was a little puzzled and said, "I didn't feel any discomfort. ”

The corner of the Sword Saint's eyes twitched slightly: "Your spiritual power is very special, and not feeling it doesn't mean that there are no hidden dangers at the spiritual level, and the elixir's ability to recover the spirit is limited, and the spirit is still very tired after the mental power is overdrawn, so pay more attention to cultivation." ”

Wu Yu blinked: "It's okay, I'm not tired." ”

The Sword Master stretched out his hand and put it on Wu Hao's shoulder: "It's not early, I'll take you back to the house to rest." ”

Wu Yu had already sensed the Sword Master's intentions, and said stupidly: "I'd better go back by myself, I'm just a little hungry, I can pick some fruit to eat when I pass by the orchard." ”

The Sword Saint smiled and said, "It's out of the way, I'll take you over." ”

"Okay then."

Wu Yu blinked, and suddenly said, "By the way, Old Wu, I encountered a few problems when I first tested the Empty Source Stone......

Questions?

The Sword Saint had a big head for a while, and he hadn't figured out the questions that Wu Hao had raised before, and if there were a few more problems that he couldn't solve for a while, he wouldn't want to sleep peacefully tonight.

"It's so late, what's the problem tomorrow, aren't you hungry, go to the orchard and pick more fruit to eat, I'll go back to sleep first."

After saying that, the Sword Saint flew away as if he had fled.

Wu Yu breathed a sigh of relief, looking at the high-grade medicinal materials that seemed to be beckoning to him all over the ground, and was thinking about whether to pick some more, when the voice of the Sword Saint suddenly came from afar.

"That's pretty much it, the medicinal materials in the medicine garden are what I keep to pass the time for the development of new pills, don't pick them again."

There are so many medicinal materials in the medicine garden, what's wrong with taking some medicinal materials, besides, the two of us are still alone, it's really stingy.

Wu Hao secretly scolded himself, but he knew that the cultivation of the Sword Saint had reached the peak of the Holy Realm, and only by going to the Upper Realm could he go further, and it was indeed not easy to stay alone in this small world for so many years, unable to cultivate, unaccompanied, and without other entertainment activities, and could only rely on the development of new pills to pass the time.

There seem to be a lot of medicinal materials in the medicine garden, but for the level of the Sword Saint, the medicinal materials consumed to develop the pill are also massive, Wu Yu collected the medicinal materials just for the occasional need, if he really needs any medicinal materials in the future, he can also find them himself, besides, he has already taken dozens of high-grade medicinal materials that are enough to be used as the main material, which is enough, and it would be too greedy to take more.

Of course, the most important reason is ...... The Sword Saint has already said it so clearly, if he doesn't know each other again, maybe he will come over and forcibly pick people up.

After glancing at the medicine garden, his gaze lingered for a little on the three holy medicine plants, and Wu Yu turned around and left the medicine garden.

When he came to the orchard, Wu Hao picked a few fruits casually and squeezed them gently, the flesh that was originally quite hard suddenly softened, and because the force was well controlled, the peel was not broken at all.

As soon as the Xuan Qi was wrapped, Wu Yu collected these soft fruits into the Empty Source Stone.

Although the soft fruits are more likely to rot, this process still takes a few hours to see the effect, so Wu Yu is ready to go back to sleep first, and wait tomorrow to see the changes in these fruits in the Empty Source Stone.

As he walked towards the wooden house, he picked a few fruits to eat, and the rich Xuan Qi filled his entire mouth with sweet juice in one bite.

Xuanguo, it's still a Xuanguo with a high grade!

Wu Yu's eyes lit up, and he ate the fist-sized fruit in three or two clicks, and began to pick the fruit hanging from the tree with both hands.

It's not that Xuanguo is so precious to him, it's just that he clearly remembers that after eating a few Xuanguo in the Longyin Mountain Range that day, he didn't feel hungry all day, so Wu Yu felt the need to reserve more for Xuanguo, a very hungry 'strategic' material.

"What are you doing?"

The Sword Saint ran over again at some point, looking at the Xuanguo in Wu Hao's hand, as if he saw some strange unknown species: "Why are you picking so many fruits?" Ready to eat it as a meal? ”

Wu Yu nodded, there was nothing wrong with what the Sword Saint said, it was a pity that Xuanguo was so hungry that he didn't use it as a meal.

Xuanguo is easier to absorb refining cultivation resources than Xuanjing, if Long Tao and Wang Shangyou knew that Wu Hui was going to eat Xuanguo as a meal, they would definitely be so angry that they rushed up and beat him, of course, if this really happened, it was more likely that they were slapped to the ground by Wu Hao's backhand.

The Sword Saint originally just said it casually, but he didn't expect Wu Hao to really have this kind of thought, and the corners of his eyes couldn't help but twitch twice.

If it weren't for the fact that Wu Hao was brought by him from another time and space, he might have wondered if this kid was the same person as himself...... When I was young, I never had such a strange thought.

Alas, it's so uncomfortable.

"Don't take too much, these fruit trees only bear fruit once a year, and if you take them all, I won't have anything to eat."

Compared to the high-grade medicinal materials that are used to pass the time in units of five or even ten years, these Xuanguo that are long every year and used to satisfy the appetite are nothing, so the Sword Master simply admonished, shook his head and left.

However, hearing his words, Wu Hao's mind came to mind the daily life of the Sword Saint's 'lonely and miserable', and he was a little embarrassed to continue picking Xuan Fruit for a while.

Whether the time inside the empty source stone is still has not yet been tested, and it is useless to reserve so many Xuan Fruits now, in case the empty source stone cannot be 'kept fresh', and the Xuan Qi escapes after the Xuan Fruit rots, it is estimated that it will not be so hungry.

So Wu Hao stopped what he was doing and returned to the wooden house to get some sleep first.

Lying on the wooden bed, looking at the dark roof, listening to the sound of the stream flowing slowly, and the breathing of the livestock as they slept, Wu Yu suddenly thought, can living creatures be stored in the empty source stone?
