Lu Ping got a great benefit, and knew in his heart that if it weren't for the teacher's appearance, ordinary monks who offered golden nuts would just get the special protection of the sect, and there would never be two rewards, Bao Ban and Dan Fang.

Lu Ping was grateful, thought about it, took out six more golden nuts, and said: "There are still a few remaining golden nuts obtained by the disciple, since this fruit is of great use to the monk to strengthen the physical body, the disciple has not dedicated it to the sect, but he has forgotten the teacher's truth." ”

Liu Zhenren looked at the golden nuts in Lu Ping's hand, his eyes were also bright, and he "giggled" and laughed: "You kid is really smart, this golden nut is indeed of great use to the teacher, say, what do you want, although the teacher is not as good as the ancestor of this faction, there is no reason to let his apprentice suffer." ”

Lu Ping hurriedly waved his hand and said: "It is natural for a disciple to respect the teacher, and there is no reason to ask for benefits from the teacher." ”

Liu Zhenren said with a smile: "Where is there a teacher who covets the treasures in the hands of his disciples, no matter what, since you don't say it, I will give you another treasure ban as a teacher." This treasure forbidden is also a pure water attribute, which can be complemented by the treasure forbidden you got before, and can be used to improve your natal magic weapon in the future. It's also good if it's used to refine other magic weapons. ”

Lu Ping looked at the two extra treasure prohibitions in his hand all of a sudden, and wondered: "Can magic weapons also be improved with different treasure prohibitions?"

Lu Ping knew that this was the time for the teacher to preach to himself, once he didn't understand something, he immediately asked, sure enough, Liu Zhenren patiently explained: "The magic weapon is different from the magic weapon, the more the magic forbidden in the magic weapon is simply superimposed, the greater the power, the magic weapon is the opposite, a kind of treasure forbidden in the magic weapon is best used only once, there are two identical forbidden magic weapons The power is far less than the power of two different forbidden magic weapons." ”

Liu Zhenren paused, organized his language, and continued: "The power of the magic weapon depends on two aspects, one is naturally the embryo of the achievement of the magic weapon, that is, the quality of the top-level magic weapon, the higher the quality, the more treasure bans can be stacked; ”

Lu Ping thought that among the magic weapons he got was the superposition of two identical treasure bans, it seemed that the medicine pestle was not a good magic weapon, but its power was already jaw-dropping, and he didn't know how powerful it would be if nine different treasure forbidden magic weapons were superimposed.

This trip to the Seven Stars Heaven, in addition to harvesting a large number of treasures, Lu Ping has also made significant progress in cultivation, Lu Ping will ask Liu Zhenren one by one the problems encountered in the practice during this period of time, Liu Zhenren answered in detail, and told Lu Ping everything that should be paid attention to in the practice, Lu Ping felt that he benefited a lot, when Lu Ping said goodbye from the Chonghua Palace, most of the day has passed,

After returning to Huangli Island, Lu Ping cultivated while preparing for refining Jin Jian Dan and Dissolving Heart Pill, and at the same time instructed Fang Tao to pay attention to the news in the Demon Clan's sea area, especially the news about the North Sea Alliance's invasion of the Demon Clan's sea area.

The difficulty of refining Jin Jian Dan and Dissolving Heart Pill is undoubtedly higher than that of a half-step forging pill like Zhuyan Dan, there are only five kinds of thousand-year-old spirit grasses required for Zhuyan Pill, while there are more than twenty kinds of other five-hundred-year-old spirit grasses, and most of these spirit grasses are common in the cultivation world.

There are a total of thirty-six kinds of spiritual grass required by Jin Jiandan, of which twelve kinds of thousand-year-old spiritual grass are needed, and the remaining five-hundred-year-old spiritual grass is mostly rare species, if it weren't for Lu Ping's trip to the Golden Canyon, it would not be easy to get together, even so, Lu Ping only had enough six furnaces.

The Dissolving Heart Pill was even more difficult, and Lu Ping almost wanted to give up when he looked at the spirit grass listed in the Dan Fang. Forty-nine kinds of spirit grasses are needed to refine the Heart Dissolving Pill, and twenty-four of them are needed for thousand-year-old spirit grasses, which is comparable to refining the Forging Pill Pill.

Generally speaking, one of the criteria for reaching the pill of the forging pill stage is that the number of thousand-year-old spirit grasses in the pill has reached twenty-seven, and the difficulty of refining the heart pill is no longer below the pill of the forging pill.

Lu Ping used up more than half of the thousand-year-old spirit grass collected in the Luojin Canyon, and finally barely scraped together enough of the three-furnace spirit grass to refine the Dissolving Heart Pill.

Lu Ping finally knew why the Liao family had to venture deep into the Luojin Canyon to collect spirit grass every time the Seven Star Heavens were opened.

The refining of the pill naturally has to start from the easy one, the refining of each furnace of Jin Jian Dan takes about two days, and each time it needs two gold nuts as the main medicine, Lu Ping's first furnace of Jin Jian Dan's refining is not smooth due to unfamiliarity, and two days later, Lu Ping only took out a golden pill from the alchemy furnace full of mush.

Lu Ping took a breath and cheered himself up: "Yes, I thought that this time the whole army was wiped out again, but I didn't expect to succeed." ”

Lu Ping carefully recalled the refining process, in addition to being unskilled and subject to Lu Ping's own alchemy level, the biggest deficiency was in the process of condensing pill purification, in this process, the alchemist needed to purify the spiritual liquid, and remove the impurities in the spiritual grass as much as possible, so as to improve the quality of the elixir and improve the rate of the elixir.

Compared with the five-hundred-year-old spirit grass, the impurities in the thousand-year-old spirit grass are naturally less, but it also means that the impurities in it are more difficult to eliminate.

Lu Ping thought about it, and suddenly remembered the "Spirit Fire Forging and Refining Technique" he used when he was assisting Chen Lian to raise the "Landslide" to the top level magic weapon, and a bold idea suddenly appeared in Lu Ping's mind.

I didn't know if it was feasible to use this purification technique in alchemy, so as soon as I thought of it, Lu Ping immediately started refining the second furnace of pills.

This means that there are enough golden nuts in Lu Ping's hands, if the Dharma Ancestor finds out that Lu Ping actually uses the Jin Jian Dan, which is not worth under the pill of the forging pill, to experiment with alchemy, and uses the method of refining, I don't know if these ancestors will slap Lu Ping to death.

The first time always comes with failure, Lu Ping directly ingested the power of the blue spirit fire to purify the impurities in the thousand-year-old spirit grass during the purification process of refining Jin Jian Dan, but he couldn't control the heat in it, and directly vaporized half of the spirit liquid that these spirit grasses turned into.

Even so, the second furnace of elixir still brought Lu Ping a golden pill.

Lu Ping was overjoyed, it seemed that this method would work, but it required more refined control of the Blue Spirit Fire, and the requirements for divine consciousness were undoubtedly stronger.

Lu Ping, who had discovered the new method, was very interested and tirelessly devoted himself to the refining of the third furnace of Jin Jiandan, knowing that as long as he fully mastered the application of this purification technique in alchemy, his alchemy technique would undoubtedly go to the next level.

In the third purification, only a quarter of the spiritual liquid was evaporated, Lu Ping got two golden pills, and in the fourth furnace, Lu Ping finally completely controlled this purification technique, and the spiritual liquid was not evaporated again, and the three golden pills were baked.

With Lu Ping's continuous refining, in addition to the application of purification techniques, his own understanding of Jin Jian Dan is also deepening, and Lu Ping of the fifth furnace finally raised Jin Jian Dan's Cheng Dan rate to four layers. When the sixth furnace of elixir was successfully refined, Lu Ping looked at the four golden pills inside and knew that this was the limit that his current alchemy could reach.

Fifteen golden pills, since the box of golden nuts was obtained by Lu Ping with the help of Yin Zichu and Ji Zixuan, Lu Ping planned to give five to each of them after they came back from Jinjiao Island.
