Time flies, and half a year has passed in the blink of an eye. During this period, Lin Haoyu has been staying in the Tianxing Sect's library. Although it is not the main pavilion, the number of books on the first floor is not smaller than that on the main pavilion. However, most of the books are copies, but it is enough for Lin Haoyu!

"I'm familiar with the medicinal properties and other things, so I can try to refine elixirs. Also, the low-level herbs in the medicinal garden in the cave should have grown, and no one will think it's special at this time!" Speaking of which, shortly after I started to study alchemy, Lin Haoyu bought a batch of herbal seeds, a small part of which was planted in the medicinal garden in his cave, but more seeds were sent to the source realm. A super-large medicinal garden was opened next to a spiritual eye in the fourth area, which was very suitable for the growth of herbs. In the past six months, it was enough for the herbs planted by Lin Haoyu to grow to the point where the lowest-level elixirs could be refined.

At the same time, Lin Haoyu's knowledge of alchemy has been initially improved. He has read through the entire library's first layer of books related to alchemy, including those books introducing medicinal properties. Lin Haoyu also has a very thorough understanding of them.

At this time, Lin Haoyu finally decided to leave the library and go back to start refining alchemy, and strive to learn alchemy as soon as possible.

"Print the refining experience of this marrow cleaning pill. Let's refine the marrow cleaning pill first when you go out!" When leaving, Lin Haoyu chose to copy a book and took it out.

The marrow-cleaning pill can be said to be the lowest level pill in the entire Tianluo Spirit World, but it is also the foundation in the basics. The consumption is second to none among all kinds of elixirs. Moreover, the value of the high-quality marrow-cleaning pill is also quite amazing, so Lin Haoyu chose this elixir as his pioneering work.

"Introduction to the book, the marrow washing pill is divided into nine grades, the lowest in the first grade and the highest in the ninth grade. Every time one grade is increased, the value will increase in geometric multiples. It seems that this kind of pill is the most profitable, at least among the low-level pills, it can be said to be unparalleled!" Looking at the crude alchemy furnace in my hand, Lin Haoyu put several prepared iron wire grass and golden bone flowers into it. He emitted the fire of true essence and began to refine it.

A flame rose up and enveloped the alchemy furnace. Lin Haoyu carefully controlled the Yuanhuo according to the alchemy steps described in the book and baked the alchemy furnace.

"puff!"

But soon, a stream of black smoke came out of the alchemy furnace, needless to say. The furnace marrow washing pill was completely ruined.

"Uh!" Seeing this, Lin Haoyu couldn't help but be stunned: "What's going on? My steps just now are completely fine? Why is it useless?"

During this period, Lin Haoyu has seen many books on alchemy experience. He thought that the steps just now were not bad, but then he started to refine the furnace marrow washing pill and was completely scrapped. It really made Lin Haoyu speechless. He didn't expect that his alchemy technique was so bad. Is it really difficult to learn alchemy!

Although Lin Haoyu's hand was huge in number of iron wire grass and golden bone flowers, he planted tens of thousands of trees in the source realm and consumed them at will. And he could plant more, but Lin Haoyu quickly realized that it was not a problem with his own alchemy technique just now. But in other aspects, this cannot be corrected by trying a few more times.

"By the way, the true essence in my body is innate true essence, which is completely different from other true fairy cultivators. Even many god and demon cultivators may not have innate true essence. It seems that the problem lies here. The innate true essence of the Yuanhuo should be much stronger than the Yuanhuo of the ordinary true essence! Well, you should check out the alchemy methods of those big guys. The difference between the Yuanhuo of the innate true essence and the Yuanhuo of the ordinary true essence is not mentioned in their experience. Could it be that I can only see the information about the information about the Yuanhuo of the innate true essence after becoming a disciple of the True Immortal Realm and climbing to the second level of the library?" At this time, Lin Haoyu also figured out this point. He understood that the Yuanhuo formed by his innate true essence was too domineering, which made the material of the marrow washing pill burn instantly and completely scrapped.

Speaking of which, the requirements for entering the library are quite strict. Among the disciples of Tianxing Sect, the outer disciples of the True Immortal Realm can only enter the first level of the library. If they are inner disciples, they can climb to the second level. At the same time, the outer disciples of the God and Demon Realm can also climb to the second level. However, if you want to climb to the third level of the library, you need to become an inner disciple of the God and Demon Realm or break through to the Spirit Fairy Realm!

It is precisely because of this that everyone strives to be the best in the Tianxing Sect just to obtain more resources, including practice techniques and share of spirit stones and herbal medicines!

"Don't worry, challenge it!" Although Lin Haoyu wanted to keep a low profile, it seems that if he continues to keep a low profile, he will definitely not be able to get up for a long time. Originally, he used alchemy as his source of income, but due to the innate true essence, if Lin Haoyu could not climb to the second floor of the library to view the books in it, he would not be able to refine alchemy at all. This would form a vicious cycle. Unless Lin Haoyu broke this situation, he would have to temporarily sink, which was something he didn't want to see.

Moreover, after reading the book for half a year, Lin Haoyu also had a deeper understanding of the situation of the Tianxing Sect and the Tianluo Spirit Realm. He knew that blindly keeping a low profile would have no way out in the Tianluo Spirit Realm. When necessary, he still needed to show his strength. If he happened to attract the attention of a powerful or even a super powerhouse and was accepted as a disciple by him, he would have a bright future!

At this time, Lin Haoyu was already a disciple of the Tianxing Sect, and he didn't need to be too low-key in some matters. He directly chose to challenge the chief disciple of the True Immortal Realm - Ba Budu!

Babudu is a true peerless genius. He even defeated many cultivators in the True Immortal Realm when he was in the Yuanshen Realm. After he arrived at the True Immortal Realm, he directly challenged an inner disciple of the True Immortal Realm and won the battle, winning the seat of an inner disciple. Then Babudu used the remaining two challenges to challenge the chief disciple twice in succession, and successfully won the second challenge, becoming the chief inner disciple of the true Immortal Realm practitioners of the Tianxing Sect. More than ten years have passed so far, and Babudu has been challenged many times, but none of them can win the final victory! You know, during this period, even many inner disciples participated. It can be said that Babudu is the strongest man in the true Immortal Realm of the Tianxing Sect. As the chief disciple of the True Immortal Realm, the quota for the spirit stones he obtained is also quite amazing.

In fact, as long as you become an inner disciple and occupy one of the 100,080,000 seats, you will get an additional spiritual stone quota. However, as you rank higher, the spiritual stone quota will increase dramatically. If you become the chief disciple, the spiritual stone quota can almost be compared with the outer disciples of the God and Demon Realm.

"What? Someone has challenged Babudu again?"

"Yeah, the news is correct, the challenge application has been sent!"

"Haha, there's a lot of fun to watch now. I thought the school entrance exam was not interesting before, but since someone challenged Babudu, it's necessary to go and have a look!"

"Too…"

After Lin Haoyu's challenge application was issued, it soon caused a sensation within the Tianxing Sect. As the chief disciple of the Tianxing Sect's True Immortal Realm, Babudu has completely gained fame. In recent years, no one dared to challenge him, because Babudu has reached the third level of the True Immortal Realm at this time. Compared with his challenge, he has made great progress. Therefore, no short-lived cultivator dares to challenge Babudu, but now a young man appears. It will be the next round of exams soon, and there will be fun to watch at that time!

Lin Haoyu also needs to participate in this round of school exams, but he has sent a challenge application. As long as Babudu takes it, he will not have to participate in the school exam. Once he succeeds, he will become the chief disciple of the True Immortal Realm of the Tianxing Sect and he does not need to participate in the school exam. Even if he fails, he will exert his combat power through this challenge, which is equivalent to a demonstration, so that the person who is responsible for the school exam can evaluate his strength and give him a ranking based on this evaluation.

Time flies, and more than ten days have passed in a blink of an eye. The school examination for disciples of the True Immortal Realm of Tianxing Sect has also begun. However, before the school examination conference is launched, there is a grand challenge event.

There were hundreds of millions of practitioners at this school entrance examination, including outer disciples and inner disciples of the True Immortal Realm of Tianxing Sect, and many disciples of the God and Demon Realm. Although most of the disciples of the God and Demon Realm are outer disciples, it is enough to prove their attractiveness.

Most of these cultivators in the God and Demon Realm came for Babudu. They were very optimistic about Babudu and felt that he might grow into a powerful person in the future. Naturally, they felt that Babudu’s fighting methods were very special and they were planning to learn at this time.

As the strongest disciple of the True Immortal Realm who was challenged this time, Ba Budu can choose the number of games at will after accepting the challenge, and he chose the first game, so Lin Haoyu was called up in the first challenge before the school entrance examination.

Speaking of which, as the challenged party, Babudu can choose three of the multiple challenges applications, but only one person challenged him this time, that is Lin Haoyu, so Babudu can only choose this opponent.

The two walked onto the stage and looked at Babudu, which was emitting a powerful aura on their bodies. However, Lin Haoyu smiled slightly, released the Chaos Pearl and smashed it over.

"Boom!"
Chapter completed!
