At first sight of the little red fruit, Lin Dong's first thought was-spirit fruit!

"Do you know what this thing is?" Ren Qingsong sold Guan Zidao.

Lin Dong said without hesitation: "Good thing! ”

Ren Qingsong choked and said helplessly: "This fruit is called Wanhong Fruit, a seventh-order spirit fruit." ”

"Seventh Order?" Lin Dong lost his voice and said, "This is a seventh-order spirit fruit?" ”

Ren Qingsong was obviously very satisfied with Lin Dong's expression, Wu Zi picked up the teacup on the table, took a sip, his lips smacked, seeing that Lin Dong couldn't help but ask, so he explained in a timely manner: "Wan Hongguo is the main refining material of the seventh-order elixir Baili Dan, Baili Dan has a peculiar effect, and after taking it, it can expand the capacity of the dantian. What benefits will expanding the capacity of the dantian bring to cultivation, you should be clear, right? ”

Lin Dong hesitated for a moment and asked, "The capacity of the dantian has increased, and if you want to break through to the next realm, you should need more spiritual power, which is equivalent to the increase in the time it takes to break through." If that's the case...... After the breakthrough of Bailidan, will the medicinal effect disappear? ”

Ren Qingsong approvingly: "Clever! Once the medicinal effect of Baili Dan disappears, the dantian will also return to normal, and the extra spiritual power of the previous realm will become more refined together with the original spiritual power after being compressed by the dantian that has not yet been formed. ”

Lin Dong is overjoyed, the big realm is a quantitative leap, and the small realm is a qualitative change. Every time he broke through a small realm, his spiritual power would be compressed to one-ninth, that is, he would be nine times purified. And after the breakthrough, the initial cultivation is the most difficult, because the more spiritual power running in the meridians, the more amount of spiritual energy that can be drawn into the meridians.

If it takes 100 days to reach the 5-fold 2 points of the 5-fold period of the Agile Period, and it only takes 50 days to reach the 5-fold 3 points of the 5-fold 2 points of the Agility Period. It takes more than 30 days for 3 points to reach 4 points, and the reason is that the spiritual power of the five two-fold and three-point spiritual power in the spirit period is twice and three times that of one point, and the speed of absorbing the external spiritual energy is also twice and three times.

If you don't take into account factors such as the use of spirit stones and the more spiritual power, the greater the obstruction of impurities in the meridians, the fivefold one point of the spirit period to the five folds and two points of the spirit period occupy almost one-third of the time.

Even if various factors are added, each realm from one point to two points occupies nearly one-fifth of the time.

This also means that when taking Baili Dan and about to break through, the spiritual power in the dantian is not only more abundant than others, but after the breakthrough, the initial spiritual power is more, and the starting point of cultivation is also higher.

The price is just that the previous realm is slower, but the starting point of the previous realm is that the spiritual power overflows before taking Baili Dan, and it doesn't take much time to fill the newly increased capacity.

Thinking about it, Lin Dong hurriedly asked, "How much can this Baili Dan expand the capacity of the dantian?" ”

Ren Qingsong smiled and replied, "About double!" ”

Lin Dong smacked his tongue, if the spirit period quadruple took Baili Dan, it might have to be pushed back by about a day and a half to break through to the spirit period five, but the time required for the spirit period five to the spirit period six can be advanced by one-fifth, to say the least seventeen or eighteen days.

"Dean Ren, what materials do you need for this Baili Dan?"

"Don't think about it." Ren Qingsong said unceremoniously: "Don't say that the refining method of Baili Dan is the secret of the Tiandan Sect, even if you know the required materials and refining methods, the seventh-order elixir, even if you have the materials, you will not be able to ask a high-level alchemist to help you refine Baili Dan." ”

Lin Dong was dumbfounded, he didn't know the materials, he didn't know the refining method, why did you move a Baili Dan out to tempt people?

"But ......" Ren Qingsong closed the wooden box and said indifferently: "If you eat Wanhong Fruit alone, you can also broaden the dantian, one Wanhong Fruit is said to be able to refine five Baili Dan, if you divide it into five parts to eat, although the medicinal effect is far less than that of Baili Dan, but if you eat it whole, it is no less than half Baili Dan." ”

Lin Dong let out a long breath, half of the medicinal effect can also widen one-half of the dantian, although there is no hope for seventeen or eighteen days in advance, it is not difficult to seven or eight days.

With a move in his heart, Lin Dong asked, "What if the two eat together?" ”

Ren Qingsong couldn't cry or laugh: "The teacup is full, and no matter how much you pour, it's in vain." According to your idea, if you eat one hundred and eighty Baili Dan or Wanhong Fruit in one go, after breaking through, wouldn't you just jump to a big realm? ”

Lin Dong looked stupid.

"Take it!" Ren Qingsong put the wooden box in Lin Dong's hand: "This surprise is not bad, right?" ”

"It's really good." Lin Dong nodded and said expectantly, "Where did Dean Ren get it?" Can you get more? If it is exchanged for something, all the spirit stones and silver will be paid by me. ”

"If I can get a few more, why should I wait for you to reach the fifth level of the spirit period before giving it to you, isn't it better to give it to you in the fourth level of the spirit period?" Ren Qingsong said helplessly: "The dean of the Martial Arts Institute of Qiufeng Mansion likes to plant spiritual materials, and I am hard to grind, and it is not easy to get two." ”

"Won't he exchange things for him?" Lin Dong asked.

"The spiritual materials are all his precious bumps, unless you can exchange them for better spiritual materials, how can he look at any spirit stones and silver." Ren Qingsong shook his head and said, "What's more, the more high-level spiritual materials, the more stringent the planting conditions, and he only transplanted one tree in total." Moreover, the maturity period of the Wanhong tree is once in 70 years, and he transplanted small trees, and the fruit bearing rate is extremely low, it is estimated that more than 20 will be harvested at a time. After more than 20 years, some of them have been given away, and if I hadn't known him for decades, I wouldn't have thought of half of them. ”

Hearing this, Lin Dong couldn't help but dispel the idea of asking for a few more Wanhong Fruits, but he had already secretly decided in his heart that just because this dean of the Autumn Wind Mansion Martial Arts Academy might have seeds that Gu Huan Sect could not collect, he would definitely have to visit him in the future.

Putting the wooden box into the mobile counter, Lin Dong spoke: "Dean Ren, for the sake of my cultivation, please trouble you to get old." ”

"What's polite, I'm also here to get promoted early." Ren Qingsong waved his hand and said: "Wan Hongguo remember to eat it when the seventh level of the spirit period and the eighth level of the spirit period are eightfold, so that there will be more time in advance." ”

"Hmm!" Lin Dong nodded, if it weren't for the fact that this ten thousand red fruits were given by Ren Qingsong, he even wanted to save it until after breaking through the agility period before eating it, the effect would be better.

"By the way, remember that this ten thousand red fruits must not be packed with other things." Ren Qingsong explained: "The wooden box I just gave you is made of the trees of the Wanhong Tree, and the leaves inside are also Wanhong Leaves. ”

"Understood!" Lin Dong nodded again.

Taking out a porcelain bottle from the storage spirit ring, Ren Qingsong handed it to Lin Dong: "Inside is a three-month share of the Gathering Spirit Pill, which can almost support you to break through the fifth level of the Spirit Movement Period, if you can use it up in advance, I won't be able to get the surprise, but I must find a way to raise more spirit stones for you." ”

"Well, I guess Dean Ren can save a lot of spirit stones."

Lin Dong smiled bitterly, if the inn system can be upgraded to level 4, the cultivation speed can be accelerated by more than twenty days, but the problem is that if you can't think of a way to solve the upgrade task this time, you can't complete it in three or five months.
