Zhang Yifan took a Dan Fang from Lu Tianyang's hand, and after examining it carefully, he hurriedly suppressed the ecstasy in his heart, and his face was browning.

The pill prescription provided by Lu Tianyang is called Huang Yun Dan, which is a kind of pill that can be very obvious to improve the later cultivation of Jindan.

Huang Yun Dan is relatively simple to refine, it is made from 2,000 parts of Huang Qi grass and 3,000 parts of Rue root. Both the yellow qi grass and the root of the kidney are easy to obtain, even from the previous year.

This is the reason for Zhang Yifan's ecstasy, as long as the elixir can be easily obtained, the pill is the best pill for him.

As for Huang Yundan, because it has a kind of bitterness, no matter how clever an alchemist is, it can't be completely eliminated, and after swallowing, there will be some damage to the monk's meridians and internal organs.

The accumulation of bitterness has irreversible damage to the monks. This is also the reason why Lu Tianyang did not recommend Zhang Yifan to swallow it.

"Thank you, Uncle Lu, although this Danfang has some flaws, it has some research value for me, so I will accept it. Zhang Yifan said to Lu Tianyang.

"Well, you know it's a big deal. Lu Tianyang saw that Zhang Yifan seemed to be very interested in Danfang, so he put his mind at ease.

It's been almost two years since he returned to the sect, and the rumored catastrophe has never come, which is like a thorn hanging in Zhang Yifan's heart, so he has never had the heart to sink down and cultivate.

However, Zhang Yifan has a hunch that this catastrophe should be coming soon, and it will definitely not be more than two years.

After all, he heard Lu Tianyang say that the border environment around the Chu Kingdom was getting worse and worse, the number of demon beasts in the secret realms was much higher than before, and the demon cultivators of the Silver Country were ready to move.

And he also heard that the battle between the demons and demons in the Great Jin Dynasty has become white-hot, and the Wu clan has even ravaged the central region of the Great Jin Dynasty, although the entire Great Jin Dynasty is not in chaos, but it is not far from chaos.

It is said that there are not tens of thousands of monks who have fallen in the past two years, but there are also some monks in the Yuan Infant Period, and the battle is so fierce that it is appalling.

Zhang Yifan knew that there was not much time left for him to cultivate steadily, and he needed to make some preparations in advance.

He now has a complete understanding of the secret method of the Three Dan Transformation Element, so he has been cultivating, because of the lack of the best mana elixir, so the progress has not been very fast.

According to the current progress, Zhang Yifan expects that his cultivation can condense the Yuan Infant to the extent that he will have to cultivate for almost thirty or forty years, and this is still in the case of calculating that there is no bottleneck.

At the moment of the catastrophe, Zhang Yifan didn't want to drag the sect back because of this, so he desperately wanted to improve his cultivation.

This is also the reason why he is so excited to see Huang Yundan.

Compared with the slow progress of cultivation, Zhang Yifan's speed is not slow in the cultivation of flesh and blood.

In the past two years, in addition to teaching his apprentices, Zhang Yifan has also refined a large number of Heavenly Rank Blood Evil Vine Pills, which is enough for his current cultivation.

With the Heavenly Rank Blood Rattan Pill, Zhang Yifan was basically able to condense a Evil Gang in three or four days, and the Evil Gang consumed before had also completely condensed in the past two years.

At this time, in addition to the two hundred and sixteen evil gangs in Ren Du's second vein, Zhang Yifan's body also accumulated ten evil gangs in the chong vein.

In the past, it took Zhang Yifan half a year to accumulate a Pulse Evil Gang, but now with the help of the Heavenly Rank Blood Evil Vine Pill and the Seven-Star Demon Worm, Zhang Yifan can basically condense a Evil Gang in two or three months, and the efficiency has been doubled.

The reason why it is so fast, in addition to the amazing effect of the Heavenly Rank Blood Evil Vine Pill, also has a lot to do with the fact that Zhang Yifan currently has thirty-six seven-star demon worms in his hands.

After the previous precipitation and accumulation, the more than 20 six-star demon worms in Zhang Yifan's hand that had accumulated enough foundation began to break through the bottleneck, and finally twenty more six-star demon worms successfully broke through the bottleneck, and the seven-star demon worms in Zhang Yifan's hands became thirty-six.

And these thirty-six demon worms seem to be the limit of the high-level demon worms that Zhang Yifan can currently master.

Because the follow-up demon worms all blew themselves up and died inexplicably when they were about to break through, and their flesh and blood were devoured by those demon worms below the seven stars.

Zhang Yifan checked it in detail, but he didn't get an answer, but he knew that the high-level demon worms he could control were estimated to be only thirty-six Tiangang.

The evil qi emitted by these thirty-six seven-star demon insects was very beneficial to Zhang Yifan's cultivation of the "Immovable Ming King's Refining Evil Pulse Technique", which greatly improved his cultivation progress.

Zhang Yifan did not forget his purpose of cultivating a large number of insect swarms, with the help of the power of the sect and his extremely rich net worth, Zhang Yifan collected a very amazing basic elixir needed to cultivate insect beasts, and only needed to find a large number of five-colored Ling Flowers.

However, it is impossible to cultivate the demon insect swarm in the sect, Zhang Yifan has long planned for this, and he also has a place to cultivate in his heart - Da Longze.

In addition, Zhang Yifan wanted to collect and refine the elixir of Huang Yundan, and a trip to the sect was naturally in the plan.

Before leaving the sect, Zhang Yifan's guidance to Shi Xuan was not relaxed, and seeing that Shi Xuan's refining level had increased greatly, Zhang Yifan began to give him a detailed reference to the refining method of the Tiangong Battle Boat.

The Tiangong Warship is a large-scale attack, defense and flight in one magic weapon, which can be controlled by a team of twenty monks, and can stimulate the attack prohibition of the warboat to attack, and can attack eight targets at the same time, which is very powerful.

The defense of the Tiangong War Boat is amazing, the average Jindan stage monk can't break through his defense at all, and the attack is also very sharp, the strongest attack can reach the power of the six-grade magic weapon, and it can already threaten the Yuan Infant stage monk.

And the flight speed of the Tiangong War Boat is also very fast, the fastest speed can reach the speed of six hundred zhang per breath, and the general speed can also reach three or four hundred zhang per breath, far exceeding the escape technique of ordinary Jindan monks.

And the most important thing is that the Tiangong Battle Boat is very simple to control, most of the main body is driven by high-grade spirit stones, and there is no need to consume the mana of the monks, only twenty monks are needed to control it, and there is no even need for Jindan stage monks.

A team of twenty monks can all be composed of monks in the foundation building period, and it is easy to deal with ordinary Jindan period monks or a team of hundreds of monks, and they can come and go freely.

It can also be composed of monks in the foundation building period led by the monks of the Jindan period, and according to expectations, the highest strength shown can actually be compared with the monks of the Yuan Infant Period, which is very practical.

Once such a powerful Heavenly Crafting War Boat is refined, it will have a qualitative improvement in the strength of the sect, and it will also be an important means to resist the catastrophe for the entire Chu State Immortal Cultivation Realm.

However, the difficulty of refining the Heavenly Crafting War Boat is also very high, relying on one person to refine it is estimated that it will not be able to refine one for decades, and a group of refining masters must cooperate.

This matter was led by Shi Xuan, and the Burning Sky Valley cooperated with the refining master of the Fire Separation Sect, and the progress had reached the most critical stage.

Shi Xuan has not been able to progress at that stage because he has not comprehended thoroughly.

Zhang Yifan learned a piece of news from Shi Xuan that surprised him.

The Tiangong Battle Boat was actually comprehended by Shi Xuan from the Heavenly Craftsman Secret Scripture, Zhang Yifan was shocked when he heard the news, you must know that he did not comprehend the Tiangong War Boat from it at that time.

Zhang Yifan hurriedly asked Shi Xuan about the details, and Shi Xuan told Zhang Yifan without reservation.

Then Zhang Yifan began to check the refining method and some details of the Tiangong War Boat.

For several days, Zhang Yifan was immersed in the refining method of the Tiangong War Boat, and he understood a lot from this refining method, and he also made some discoveries.

This Tiangong Warship refining method seems to have some connection with the "Tiangong Silver Codex", which makes Zhang Yifan understand the refining method of Tiangong Warboat very quickly, and soon pointed out the direction and path of development for Shi Xuan.

Shi Xuan was overjoyed to see this, and his refining talent was no longer under Zhang Yifan, and he was able to understand it at all.

Zhang Yifan knew that even if Shi Xuan comprehended it thoroughly, it would take at least a year or two to think about how to refine the Heavenly Crafting Battle Boat.

The spiritual materials consumed by the refining of a Tiangong warship are more than ten times that of the ordinary six-grade magic weapon, Zhang Yifan roughly estimated, without considering the failure rate, a Tiangong warship almost needs at least twenty or thirty million lower-grade spirit stones to refine.

Moreover, the spirit stones consumed by the Tiangong Battle Boat are also very large, and it takes a day to drive, and it takes almost one high-grade spirit stone to consume, and if you fight with all your strength, the spirit stones consumed will be even more.

Such a treasure is not something that ordinary sects can drive, and only wealthy sects like the Seven Great Sects of the Chu State can use it.

Zhang Yifan saw that the affairs of the sect were almost busy, so he began to leave the sect and act according to the plan.

He told Lu Tianyang, and the other party told him to be careful, and then gave him a special Ten Thousand Miles Flying Sword Talisman to deliver emergency news.

Zhang Yifan went to Jiangyue Daofang City first, and saw that the scale of Jiangyue Daofang City today is much more prosperous than when he left, and he has a sense that things are wrong.

Because he was very familiar with Jiangyue Daofang City, Zhang Yifan quickly searched for some of the things he needed.

Subsequently, Zhang Yifan went to Chuxiong City first.

After arriving in Chuxiong City, Zhang Yifan looked for Xu Lianfu for the first time, and found that the other party had already fallen, and fell in a secret realm more than ten years ago.

Xu Lianfu's fall made Zhang Yifan very sad, the only relative in the world, left him before saying goodbye.

Zhang Yifan entered the Xu family, and after giving three sticks of incense to Xu Lianfu's tablet, he left without looking back, making the elders of the Xu family look at each other, but they were helpless.

Subsequently, Zhang Yifan was about to visit Wu Huan'er, but he was greeted by a pair of male and female monks who looked Zhouzheng, and the two looked somewhat similar, and at a glance they knew that they were from the same group.

This pair of young male and female monks are both good in cultivation, and they are already in the Great Perfection realm of the foundation building period, and their breath is not triggered, and they are obviously not ordinary monks.

"Hehe, is it Senior Zhang, but are you looking for the eldest sister?" Wu Yuer said to Zhang Yifan playfully.

"Xiao Yu'er, why are you so rude? Senior Zhang, the eldest sister is not at home, you come in first for a cup of tea, I will send a message to the eldest sister, and say that there is a distinguished guest arriving. The male monk on the side first unceremoniously reprimanded the female monk, and then said politely to Zhang Yifan.

"Since Wu Daoyou is not here, then forget it, I came to Chuxiong City temporarily to do something, so I stopped by to visit. Zhang Yifan couldn't see anything on his face, and then left without looking back, making the Wu family brother and sister a little confused.

"Xiao Shi, do you say that the person just now is really the great master Zhang who haunts the eldest sister and never forgets it? ”

"What do you know, Senior Zhang is known as the first Jindan stage monk in the Chu Kingdom, and her strength is Xuanxuan, according to the eldest sister, even if she has advanced to the Yuan Infant Stage now, she is not sure to win against Senior Zhang. Little fish, you don't know how thick the sky is!"

"Hmph, can I not know this, I just deliberately wanted to get close to Senior Zhang and fight for the opportunity for the eldest sister. You said that the eldest sister hasn't found a Taoist partner for so long, it's really sad. ”

"You'd better take a look at yourself first... That's a lot to worry about. ”

The two began arguing again.

At this time, Zhang Yifan had already walked away and did not notice the conversation between the two.

In fact, Zhang Yifan himself was very strange why he wanted to go to Wu Huan'er, maybe he subconsciously wanted to find someone to confide in his heart, after all, Xu Lianfu and Wu Huan'er were masters and servants.

Then Zhang Yifan looked for Roger and Xiang Yunxiang, and found that his two old friends had run out of life and passed away.

Zhang Yifan was depressed and just wanted to get drunk, so he came to the drunken fragrance building.

When Yang Ping saw that Zhang Yifan was actually here, she was stunned and at the same time, she also warmly entertained him.

"Yang Daoyou, please bring me a few bottles of seven-day incense. Zhang Yifan said lightly.

"It seems that Brother Zhang has encountered some unhappy things, I don't know what happened, so Brother Zhang looked so depressed, say it, sister, I will help you enlighten me. This century-old bottle of sinister incense is cheaper for you. Yang Ping sat next to Zhang Yifan with a big grin, and casually took out a bottle of wine with a rich aroma from the storage bracelet.

Zhang Yifan, who originally had some mind about the defense of men and women, didn't say anything at this time.

He took the bottle and drank three glasses first.

"Good wine!" Zhang Yifan said loudly.

"When you sing about wine, life is geometric, such as morning dew, and there are many bitter days. Sister Yang, why do you say that people die and cannot exist forever?"

Yang Ping's eyes lit up, and she said softly: "Good poetry." Brother Zhang, what you are talking about is the lifelong pursuit of our monks. Death is a cycle of heaven, and the pursuit of immortality is against the sky. Do things against the sky, you say how difficult it is to live forever. Life expectancy is limited, death is the normal destination, even if it is a monk in the infant stage, he has only lived a thousand years, and he has experienced many calamities during this period. If you want people to be immortal, how much skill do you have to do to do it?"

"I just want my friends and family to be around me all the time... Even, they are dead, I hope to be able to resurrect them. Zhang Yifan took another big sip of seven-day incense, and said the greatest pursuit in his heart with the strength of wine.

"I said, Brother Zhang, I think you have been stimulated too much to say such nonsense. It is extremely difficult for a person to live forever, ethereal, and you have to take the people around you to live forever together, that is too against the sky, this has no good end. Brother Zhang, I advise you to let go of this unrealistic thought, otherwise it will be difficult for you to pass the catastrophe of the Yuan Infant. Yang Ping raised her eyebrows and said persuadingly.

"Why?" asked Zhang Yifan Zou Mei.

"I don't know the specifics, but the old man told me, so I think there should be some truth. Yang Ping explained.

Zhang Yifan suddenly realized that Yang Ping's grandfather was one of the three major loose cultivators, a wine sword immortal, a famous great monk in the late Yuan Infant period of the Chu State, and what he said must have some truth.

"Brother Zhang, as a monk, be firm in your Taoist heart. It is not uncommon for people around you to pass away, and this matter is constant for eternity, and it is not something you can change if you think about it. Immortality is hard. Yang Ping sighed.

"Yes, immortality is hard. Zhang Yifan took another big sip and sighed.

"But no matter how difficult it is, I'll try..."Zhang Yifan thought in his heart.

(PS: Change first, change later.) Longevity is difficult, may the Taoist friends live the rest of their lives, peace and joy. ）
