On the way back, Pei Peiqiang once again expressed his desire for Gangu Yu to improve the soil quality of her field and give her some sweet potato seedlings.

"Sweet potato seedlings are a small thing, as long as there is enough gold ore to please Mother Nature and her old people, you can have as many sweet potato seedlings as you want. Gangu Yu flickered without blushing and heartbeat, "But the soil matter is a bit troublesome, and I must have enough mana to do it...... Anyway, why did it take so long for my mana to recover so much?"

"If a magician's mana recovers on his own, it is indeed very slow. At the mention of this, Pei Pei was also a little helpless, "Meditation is a magician's method of cultivation and speeding up recovery, but the effect is also very limited. Other than this, you can only rely on external forces. ”

"With the help of external forces?" Gan Guyu became interested when he heard it, "As long as there is a way, it's good!"

"But it's not cheap. Pei Pei stuck out his tongue and said, "But you really have such a ready-made one, which is your natural magic crystal, it depends on whether you are willing to use it." ”

"That's really reluctant. Gangu Yu spread his hands. During this time, he also figured out the approximate price of the magic crystal, like his seventh-order natural magic crystal is more useful, it is a priceless treasure, and it is too violent to restore mana.

"Stingy, I know you can't bear it. Pei Pei immediately stuck out his tongue at him, and there was a burst of contempt. Gangu Yu just spread his hands and didn't bother to argue with her. But Pei Pei said: "But there is another way, I can do it!"

"Oh, what's the solution?" said Ganguyu.

"Hehe, wait for me tomorrow by my wheat field, and you'll know when the time comes. Pei Pei licked her lips and smiled mysteriously, but she directly pushed open the door of her own residence, dodged in, and did not forget to wave her hand to Gan Guyu at the end, and closed the door.

After she was the only one left, Pei Pei carried the sweet potatoes that Gangu Yu gave her, licked her lips and rushed into the kitchen in a hurry, as if the three sweet potatoes she had eaten before had fallen into the dimensional world......

The next day.

Gangu Yu had been resting at the edge of Pei Pei's field for a long time, and Pei Pei trotted over with a wooden tray in a sweat.

"Why did you come here? I remember you always woke up early?" Gan Guyu nodded at her field, "I've helped you change some soil, but my mana has dried up again." ”

"Well done. Pei Pei was stunned, and then praised very vigorously, like a small landlord who exploited her own labor. But then she still showed a slightly gentle side, and handed the wooden plate in her hand to Gangu Yu: "Well, this is a consolation for you, for restoring mana, accept it gratefully." ”

Gangu Yu looked at the plate: "Oh, grapes, do you still have this good thing?" As he spoke, he picked up a grape and threw it into his mouth without peeling the skin.

"Hey, I haven't introduced you to grapes, do you?" Pei Pei said in surprise. But soon she became anxious: "Hey, what are you nervous about?"

Because Gangu Yu had not been able to throw the grape into his mouth for less than three seconds, he immediately spit it out, and spat on the ground. When he looked at Pei Pei again, his facial features were almost tangled: "I said, are all the things you take out to entertain people so virtuous? I won't talk about the cake that was so hard that it can break people's teeth last time, your grapes are sour like this, can you eat them?"

Seeing that Gangu Yu's cheeks were still twitching, Pei Pei's voice was much quieter, and he instantly completed the transformation from a landlord's wife to an angry little daughter-in-law: "I don't like to eat grapes either, but it's so sour, what can I do? Isn't this to restore your mana......"

Speaking of this, Pei Pei glanced at the grape that was spit out by Gangu Yu with some distress: "It's such a good grape, it's such a waste......"

Gangu Yu heard some taste: "What, this grape is very precious, and it can also recover mana?"

"Very precious, very precious, very precious!" Pei Pei emphasized, "Fruits and vegetables are also rare in the natural forest, and they are almost impossible to see on the mainland. Because fruits like grapes can help magicians cultivate, and the effect of eating one can be meditated for several days, so the price has long been speculated by magicians to an outrageous level, and ordinary people can't afford to eat it. It can be said that the fruits on the salty continent have long been reserved for magicians and nobles. ”

"Do you mean, these sour and astringent grapes, or are they luxuries?" said Ganguyu, blinking his eyes and reconfirming with an incredulous expression.

"yes, luxury. Pei Pei's cheeks puffed up, "However, some people still don't appreciate it! There are only two bunches on my vine, so I'll bring you one bunch......

Gangu Yu coughed lightly twice with an embarrassed face, and hurriedly changed the topic stiffly: "I know grapes, but this is the first time I've heard that grapes can restore mana and help magicians cultivate." ”

"There are only a few vines in the natural forest, and the vegetables are only two fields of greens. "But these fruits and vegetables are the most sought-after, and every year the Cypros Wizard Academy buys most of them at a high price, and the sisters eat the rest themselves." I've eaten grapes once, hehe......"

"And then I never ate it a second time, didn't I?" Gangu Yu rolled her eyes angrily, "Only those idiots would eat this sour thing...... However, grapes can help magicians cultivate, what is the principle of this?"

"Grapes and greens can restore mana, and sweet potatoes seem to have this effect as well," Pei Pei added...... "but who knows why." As long as it can regain mana, isn't it?"

Gangu Yu was stunned, when he harvested sweet potatoes before, he took two mouthfuls of raw sweet potatoes demonstratively, and then went to prepare food for the women, and he didn't touch the boiled sweet potatoes and baked sweet potatoes in the back, but he didn't feel this.

"Why the hell? This ordinary grape, an ordinary sweet potato, actually has this wonderful use after arriving in the salty continent......" Gangu Yu picked up a grape, swallowed it with the sourness, and it didn't take long for his mana to be restored, which was indeed much more efficient than his own meditation.

Curious, Gangu Yu picked up a grape again, but this time he didn't eat it, but silently recited a short incantation in his heart. Soon, as Ganguyu's mind changed, the tissue structure of this grape, from the cells to the molecular components, clearly appeared in his mind.
