Han Dong looked at the void under his feet, the stars around him kept rotating and surrounding him, listening to the mechanical sounds explaining the rules of the Tower of All Things, and his heart was confused.

He knew that all this in front of him was an illusion, an unreal image created by the Tower of All Things, but with his high-level strength in the Glimmer Light Realm, he could not see any flaws, as if he was really in the starry sky, which made him a little confused.

The rules of the Tower of All Things are very simple. As long as you have the potential for alchemy, you can enter the Tower of All Things for assessment. If you enter the Tower of All Things for the first time, you will start testing the potential from the first level, and each level will increase the difficulty of alchemy until the failed level.

Many of the people who can climb the 99th floor tower on the ranking list did not step on the 99th floor for the first time, but have been here many times. Every time they improve their alchemy, they will come here to test their strength.

But you will only get rewards for the first time. Through one layer, there will be rewards. Once you fail, you will leave the Tower of All Things. No matter how many times you come or how many levels you climb to, there will be no rewards.

Moreover, there are restrictions on entering the Tower of All Things. You must be at the level below the Alchemist Master before you can enter. Otherwise, you can only simply test your alchemy level and you will not receive any rewards.

"Your alchemy has a contract slave bonus. After starting the test, the bonus will be isolated and left the Tower of Everything to recover. Will you start the test?"

The cold mechanical sound rang in Han Dong's ears.

"Let's start." Han Dong nodded and said.

It was expected that Haru's alchemy bonus was stripped of, and Han Dong didn't care.

The starry sky in front of him suddenly began to change, and a mysterious force enveloped Han Dong's whole body. Soon, Han Dong felt that something seemed to have disappeared on his body, but he couldn't say exactly what he had lost.

The alchemy level is related to the success rate of alchemy, the perception of alchemy, and the understanding of alchemy drawings. The level is reduced by one level and is difficult to detect. Only during the refining process can you find that the alchemy drawing formulas that you could understand before are not understood now. The easy alchemy process before is also felt obscure now.

Soon, in the endless void, a simple alchemy table appeared in front of Han Dong, with only a few simple alchemy vessels placed on it.

If Han Dong had just come into contact with alchemy, he would be very happy to have these equipment, but now, these alchemy equipment is too simple for him, and many higher-level potions cannot be refined.

"If it's just these, it's very difficult to refine primary potions, the success rate is reduced by at least 50%, and the quality of the potions is not guaranteed." Han Dong looked at the alchemy platform and frowned.

Soon, an alchemy drawing formula appeared on the alchemy platform. Han Dong picked it up and saw that it was a recipe for recovery potion, but it was just a simple version of the primary recovery potion. The materials alone were half less, and the refining process was much simplified.

The most important thing is that even if the refining is successful, the refined potion will probably not have one-tenth of the ordinary primary recovery potion, and it has no refining value at all.

"That's it..." Han Dong just glanced at it and completely simulated the entire refining process in his mind. At this time, he felt like a high school student was returning to elementary school and taking a test of double-digit addition and subtraction.

"No wonder people who have not learned alchemy can also come to test it. However, if you don't know how to alchemy, you may not be able to wait for a few levels." Han Dong said in his heart.

"A specified time is 1 hour, and a successful refining of a potion within 1 hour is considered qualified, otherwise it will fail!" mechanical voice continued.

Han Dong nodded, and a smile appeared on the corner of his mouth. Such a simple recovery potion was simply an insult to him after refining it in one hour.

Imagine so many alchemist masters on the rankings, and they once refined such simple potions on the first level. Han Dong felt a little funny and even felt some sympathy.

Imagine a group of white-haired professors sitting in the elementary school classroom, holding pencils, and seriously doing double-digit addition and subtraction papers. This scene must be difficult to see in normal times.

Han Dong originally wanted to start refining with the knowledge and alchemy techniques he had already mastered, but after hesitating for a moment, he gave up this idea and began to refine it completely according to the techniques given in the alchemy formula.

Only five portions of herbal materials are given, which is equivalent to only four chances of failure. Once all five fail, it means that there is no alchemy qualification at all, and the test will be declared failed.

Because it has to be refined completely according to the alchemy formula, and Han Dong cannot use his spiritual power and mental power to speed up the refining process. It took Han Dong fifteen minutes to complete the potion that could be refined in just a few minutes.

Looking at the sticky liquid in the glass test tube, Han Dong suddenly remembered the first time he had refined the holy light potion in a steamer at home, and a look of memories appeared on his face.

"Successfully refined, the refining success rate is 100%, the refining time is fourteen minutes and thirty-eight seconds, and the refining evaluation is perfect!"

Soon, the mechanical sound gave an evaluation, and everything in front of Han Dong disappeared, and even the simple version of the recovery potion that he had refined before disappeared.

"Is all this illusory or real?" Han Dong was shocked again.

The previous refining process, those alchemy equipment, those herbal materials, and the entire refining process, definitely existed in Han Dong's senses, and the last finished potion was absolutely real, but why did all of this disappear in an instant?

If it was the teleportation transfer, the energy fluctuations emitted would definitely not be hidden from Han Dong's perception, but all this happened naturally in front of Han Dong!

This made Han Dong feel that everything he was experiencing was just a dream!

"The first layer of test passes, and a primary recovery potion alchemy formula is rewarded!"

A spiritual power scroll emitting a faint light suddenly appeared in front of Han Dong's eyes, floating quietly.

The primary recovery agent formula is the drug formula that Han Dong has already mastered, but seeing this formula still surprised Han Dong.

"It turns out to be an alchemy formula. Doesn't this mean that even if you don't have any foundation, as long as you have the talent for alchemy and pass the Tower of All Things, you can learn to become an alchemist by yourself?"

Han Dong was shocked, not only because of the Tower of All Things, but also because of the people who built the Tower of All Things. Their minds made Han Dong admire him.

"Only in that era, there would be such a group of people to build such a tower of all things. It is precisely because of them that alchemy can pass on and not disappear into the long river of history. It is a group of people worthy of admiration for all alchemists!" Han Dong sighed in his heart.
