Seeing Han Dong walking to the alchemy table to prepare for refining the potion, the other freshmen and students were all shocked.

But soon, they discovered that none of the alchemy materials Han Dong received were primary recovery potions, and they couldn't help but look at them curiously.

"Is this... ready to refine new potion?" a freshman student murmured in a low voice.

"Did you forget the meeting gift? Maybe he is going to refine the alchemy recipe given to us by Dean Bai..." Someone guessed.

"No, look at the one placed on his alchemy table. Isn't that hard rock block? What potion is required to use hard rock blocks?"

"Defense potion, what he wants to refine is a defensive potion!" A student stared at the materials placed on Han Dong's table and suddenly shouted in a low voice.

Defensive potions are not special potions, and they can be learned by level 5 alchemy. In other words, as long as you are a junior alchemist, you may be exposed to this alchemy formula.

Han Dong only grabbed a piece of defensive potion and started to refine it. This was his first time to refine it, so naturally he had to be more careful.

Soon, a bottle of gray potion was successfully refined. Han Dong took a look, put it aside, and began to refine the second one.

The second branch was successfully refined, but Han Dong did not rest and started to refine the third branch directly.

An hour later, sweat oozed out of Han Dong's forehead and a look of fatigue appeared on his face. There were more than thirty gray defensive potions placed in front of his alchemy table.

The other freshmen had stopped refining the potion water, looking at Han Dong like a god.

In more than an hour, more than 30 defensive potions were refined, but none of them failed. With such a success rate, not to mention that Han Dong is just an intermediate alchemist, even a senior alchemist is here, he cannot guarantee that every potion will succeed.

Everyone looked at Han Dong, who was entering a meditation state in a daze, then looked at the potion placed on the alchemy table, and kept holding back the word "animal" and didn't say it out loud.

"He, does he have the talent to improve the success rate of alchemy 100%!" someone said softly.

"Do you have this talent? Why haven't I heard of it?"

"You know all the talented skills, do you know them all?"

"There is no way you have the talent of 100% success rate, right? If you want to say that you can improve by 10% or 20%, it is possible..."

"Thirty bottles of potions, although they are only primary, they also require level five alchemy to learn. They are much higher than primary recovery potions. There is no failure once. Can you give me a reasonable explanation?"

"I can't, otherwise you can ask Han Dong after he recovers?"

...

The freshmen were talking about Han Dong's terrifying alchemy success rate, but they didn't care about the visions he had during meditation.

There are not a thousand meditation techniques passed down, and there are eight hundred meditation techniques. The vision of each meditation is different. It is impossible for anyone to understand all meditation techniques.

It was just that some students with particularly curiosity would stare at the spider web phantom behind Han Dong for a long time, marveling at it.

Soon, the phantom of the spider web behind Han Dong gradually disappeared. He opened his eyes and a light appeared from his pupils.

After regaining his mental power and spiritual power, Han Dong continued to refine defensive potions. In the inventory of the wall of Sigh alchemy materials, the materials for refining defensive potions were piled up like mountains. Han Dong could not refine even if he stayed in the alchemy room for three months.

On the other hand, the camps of the alien army have risen from the ground, and each alien tribe is distributed in all directions of the camps according to the military formation, guarding a certain direction.

In the central tent, Princess Xiya held a feather scepter and sat upright under a handsome flag. Below were the leaders of various tribes.

"Your Highness Princess, when will we attack? The little kids in the tribe can't sit still..."

"Your Highness, I heard that there are only a few thousand human soldiers guarding the city wall, and we have an army of 200,000. Even if one person spits, he can capture the city wall. Your Highness, I wonder how long we will have to wait?"

"Your Highness Princess, my Mengxiu tribe is willing to be the vanguard. As long as I give me half a day, my tribe's 30,000 disciples will definitely take this pass for the princess."

In history, alien races have never established an empire, so they have never had the title of princess.

However, there were too few students who chose the foreign attacking side this time. With the compensation of the secret realm, this group of alien students became the commander who could command the alien army.

But in fact, the alien trainees did not have a single soldier at all. The real commander of the army was still the leader of various tribes.

Seeing dozens of alien leaders asking for battle, Princess Xiya's smile froze.

Taking a deep breath, Princess Xiya stood up with a feather scepter in her hand and said softly: "All the leaders, please listen to me..."

...

Many tribal leaders were puzzled and dissatisfied with Princess Xiya's order to set up camp and build siege equipment.

Although there is a city wall opposite, there are only a few thousand human warriors defending. Even if they set up a human ladder, the warriors of the alien tribe can easily capture this pass and create siege equipment. That is something that only weak humans can do.

Some alien warriors even showed contempt on their faces when they saw alien alchemists creating siege equipment. In front of these alchemists, they mocked them as cowards who were fearless and cowards.

In the eyes of this group of alien warriors, a real warrior must dare to face blood and death. Even if it is death, as long as it can cut a mark on the city wall, it will be a place to die, and it is the work of the real warriors.

These alchemists from the alien race were actually all alien students who entered the secret trial. Listening to the ridicule of the alien warriors around them, these students were so angry that they almost vomited blood.

"It should be made to let these silly people with muscles in their minds attack the Wall of Sighs. They don't know what the Wall of Sighs means..."

"Hmph, historical records show that when the foreign army attacked for the first time, thousands of people died when they were more than 100 meters away from the Wall of Sigh. As a result, before they even approached the city wall, their morale was disintegrating and they all escaped!"

"The wall of sighing is said to be the city wall that even gods can only sigh when they see it. Do they want to break through it with their flesh and blood? It's so naive!"

"Otherwise, let's suggest to His Highness the Princess, let these guys who want to die become pioneers and test the strength of the human defense?"

"Hehe, you're so bad. Didn't you let them die? But, I like it, hehe!"

At this moment, the leaders of the alien race walked out of the central tent, each with ugly faces. When passing by these alchemists, the leaders of the alien race stared at them with their eyes squinted, snorted coldly, and walked proudly by these alchemists.

Several tribal leaders saw parts with siege equipment blocking the road, and even stepped on them and walked towards their tribe without looking back.
