"Brother Yu, you didn't know, at that time..."

In the canteen of the institute, Yang Xuan was vividly describing his experience to Zhou Yu.

"dragon?"

After hearing Yang Xuan's words, Zhou Yu was stunned.

He knew that Yang Xuan and the others had encountered a fatal crisis, but he didn't expect that they would encounter a legendary creature like Dragon.

"I didn't expect that a creature like dragon actually exists."

Zhou Yu expressed emotion on his face, but also felt a little regretful, and he failed to see it with his own eyes.

"In other words, the entrance to the Demon Domain has been closed now, so what should you do with your game?"

"I don't know, I said I was waiting for the notice, and the college should arrange another competition venue." Yang Xuan scratched his head.

At this time, senior leaders of the college also gathered at the top floor of the library.

"Owner, does the revival of the ancient monster mean that the demons in the dark gap are about to wake up?" the director of the institute asked worriedly.

As the top powerhouses among humans, they naturally know many unknown secrets.

The demons that disappeared in ancient times were not extinct, but felt that the Dharma-Ending Age was coming, so they chose to sleep.

Now with the arrival of the dark energy tide, the laws of heaven and earth will gradually recover, and those who have passed will eventually return.

Originally, a strange thing was enough for humans to have a headache. If the demons and demons were added, the situation would probably become more and more chaotic.

The old man in white robe did not immediately answer the question of the director of the institute. He closed his eyes and pondered for a moment, then slowly spoke: "This demon dragon's resurrection is just an accident, so don't worry too much."

"I can guarantee this that there will be no demons until the third wave of dark energy tides arrive."

"That's good."

Hearing this, everyone breathed a sigh of relief.

If weirdness brings endless fear to humans, then once the demon comes to the world, it brings endless destruction!

In terms of the degree of threat, the two are comparable, but in comparison, the threat of demons is more intuitive and pure.

"Okay, please wait for the second wave of dark energy tides to arrive. This is the biggest test that humans are about to face."

Neither demon nor demon, they are far inferior to the cosmic natural disasters like dark energy tides.

It is even because of the dark energy tide that the demons are given the opportunity to recover, which is the source of all disasters.

...

"The new rules of the game are coming."

The next day, the official website updated the rules of the qualifying match:

1. The competition venue has been changed from Demon Domain to Apocalypse Academy

2. The competition method has been changed from a melee in the demon world to a ring battle

3. In order to save competition time, only the top 50 students in the credits are eligible to enter the qualifying competition.

Originally, Apocalypse Academy planned to allow the top 100 students to use the Demon Domain as an arena for a three-day chaos.

If you use the credits obtained in the first stage as the starting point, if you lose one person, you can divide one-tenth of the student's credits into your own name, and then you will be eliminated directly after the credits are zeroed.

In the end, the remaining thirty people can become patrol guards.

The reason why I did not choose to select in the form of a ring is entirely because the limitations of the ring match are too great and cannot reflect a person's comprehensive qualities.

After all, hunting is weird and relied on not only personal combat effectiveness, but also on mind and teamwork.

But the plan cannot keep up with the changes. Now the demon realm cannot enter, and it is too variable to hold it directly in the wilderness, so it can only be changed to a ring battle.

The ring battle is not as good as the melee of all members. This thing takes more time. It is a bit inappropriate to choose another 100 students, so it is temporarily changed to the top 50.

This is naturally unfriendly to students who rank 50 to 100 in the first stage, but the college doesn't care about this.

The patrol guard only collects the elites, and does not even rank in the top 50, so it is not very meaningful to participate in the ring competition.

Of course, those students who deliberately hide their weaknesses are not ruled out here.

But there is no way, it’s you that you can hide your weaknesses and you can’t blame others.

"It's a risk. I've got 1890 credits, which is exactly 50th. I almost didn't get in."

"Then you are so lucky. I ranked 100th. I could have entered the market, but who knew the rules were changed temporarily, it was so painful!"

...

Looking at the changed rules, it can be said that some companies are happy and sad.

As for Yang Xuan and others, there are no worries in this regard.

Although they were basically looking for various extraordinary plants behind them, they didn't hunt monsters much.

But after all, the combat power is there. Killing a few elite monsters casually is equivalent to killing hundreds of ordinary monsters by others.

"Is it just seventh place?"

Yang Xuan took a look at the ranking and seemed to be a little unsatisfied.

As for Zhang Hao and Xining, they are also in similar rankings, ranking sixth and ninth respectively.

"It's good to have this ranking, after all, we have picked so many medicinal herbs."

In the laboratory, Xining took out a square wooden box from the space debris, which were filled with extraordinary plants picked from the demon realm.

"Not bad, with these materials, those extraordinary secret medicines can finally be prepared."

Zhou Yu opened the wooden boxes one by one, and a satisfied look appeared on his face.

It is worthy of being a demon domain, there are many high-end materials.

"Hehe, Brother Yu, wait until the potion is ready, remember to give a few more bottles."

Yang Xuan rubbed his hands with a smile.

"Don't worry, but this qualifying match will definitely not be able to catch up. I will strive to achieve results within a week."

After all, it is an epic potion. Even with the assistance of [Secret Book of Source Medicine], it is not so easy to prepare. Zhou Yu is already ready for failure several times.

"Captain, then we'll leave first." Xining said at this time.

"Well, you guys go and prepare for the competition."

After everyone left, Zhou Yu officially began to prepare the drug.

The first thing he prepared was [Extraordinary Secret Medicine? Blood Soul], and the main medicine was Blood Soul Flower.

The reason I chose to prepare this potion first is because it is the easiest of many epic potions.

Putting on rubber gloves, Zhou Yu started the extraction work.

This is the basis of drug preparation and an important step in affecting the success rate of drug.

The purer the extracted ingredients, the simpler the subsequent preparation work will be.

Fortunately, the laboratory equipment is very powerful. After more than two hours, the extraction of various raw materials has been completed.

At this time, more than a dozen bottles of colorful reagents were added on the experimental bench, which were all reagents for preparing [Extraordinary Secret Medicine? Blood Soul].

"The next step is purification."

This step tests patience, which is to continuously purify these reagents, and the purer they are, the better.

"This purity should be enough."

After spending more than three hours, Zhou Yu purified each bottle of reagent more than ten times, making its purity reach 99.99%, which has met the basic requirements of the [Source Medicine Secret Code].

The last step is reagent preparation.

This step will directly determine whether the preparation is successful or not.

Once a mistake occurs, all the efforts made before will be in vain. The most important thing is that these materials will be completely wasted.

Close my eyes and pondered, recalling the proportions of each component in my mind, and the next moment, I began the first preparation.

Zhou Yu's movements were very slow, but he was calm enough. The addition of each reagent was weighed dozens of times, and it was extremely accurate.

This process consumes a lot of energy. Fortunately, Zhou Yu's soul strength is high enough that he will not faint in the middle.

To be honest, he underestimated the difficulty of preparing epic potions.

In other words, the preparation of epic agents is not only about the chemical reactions occurring between various reagents, but also requires the consumption of mental power to harmonize.

This is the most difficult step. Without strong soul power, you can't get this.

Two hours later, a bottle of blood-red reagent appeared on the laboratory bench.

But this is not the final product, it lacks the last step, the spirit!

The [Secret Book of Source Medicine] was taken out and the supporting spirit was used on it.

No special vision appeared, but the color of the potion became darker.

Turn on [Endless Deduction], Zhou Yu got the relevant information about this bottle of potion.
