Haru looked grateful and knelt down again, thanking Han Dong for his generosity.

With Han Dong's permission, it can improve the alchemy level in the shortest time. This is probably the biggest wish of every alchemist.

The reason why the alchemist's alchemy level is difficult to improve is on the one hand because of the alchemy qualifications and on the other hand because of the alchemy success rate.

Halu was able to successfully refine a bottle of Holy Light Potion within thirty times, and his qualifications were more than half of the alchemist. In addition, Han Dong can now provide it with a large amount of materials, another issue of success rate is not a problem. It is only a matter of time before Harlu becomes a real alchemist.

It can be said that without Han Dong's support, even if Haru has the qualifications of an alchemist, it would be at least ten years later, or even longer to become a real alchemist.

"Okay, you can leave the Nightmare Tower for the time being. Without my consent, no one is allowed to enter the Nightmare Tower, including Francis!" Han Dong said.

"As for orders, master!" Haru reconciled and left.

Soon, Han Dong was the only one left in the entire Nightmare Tower.

Han Dong came to the alchemy platform and took out herbal materials from the prayer drum with a serious expression.

Cemetery moss, highly poisonous mushrooms, zombie mucus...

A bottle of dreamy tears, and a plague flower that looks inconspicuous.

These are the materials for refining powerful plague potions!

"There is only one plague flower, and it must be successful at one time!" Han Dong said in his heart.

Plague flower is a control material. If it weren't for a flower blooming from the treasure rock, Han Dong really didn't know where to get it.

Although it was the first time to refine powerful plague potion, Han Dong had repeated the entire refining process many times in his mind. He could not be matured. Even if he closed his eyes, he could complete the entire refining process.

However, simulation is just simulation after all, and Han Dong didn't know what would happen during the actual refining process.

"Originally, my alchemy was already at level 8, but now I have reached level 9. To refine an alchemy formula that only requires level 7, the theoretical probability of success is still very high." Han Dong said in his heart.

The higher the alchemy level, the higher the success rate of refining potions. Han Dong’s current success rate for refining intermediate potions such as vitality potions is at least above eight or nine levels. Such a high success rate may scare many people if he says it.

Taking a deep breath, Han Dong began to prepare before refining.

The powerful plague potion is highly toxic. Even during the refining process, there will be a highly toxic gas evaporated. If the refining fails, the toxicity in all materials will evaporate at one time. The entire Nightmare Tower will probably become a Jedi, so necessary protective measures must be taken!

Han Dong took a deep breath and began to ignite the alchemy furnace, trying to refine powerful plague potion for the first time!

Three goblins stood outside the tower, whispering to each other. Sulu and Nulu looked at Haru with respect and envy, and their faces were filled with careful and pleasing smiles.

Halu, who became an alchemist apprentice, is already an existence that Sulu and Nulu can never reach.

Previously, because Haru voluntarily became Han Dong's slave, Sulu and Nulu, two goblins, obeyed Haru's orders on the surface, but deep down they looked down on Haru, because they were free people and only did what they would do if they were slaves, once they could leave here, they could wantonly mock Haru, who had slave experience.

But now, Haru has become an alchemist apprentice and will become an unattainable alchemist in the future. Even if the three of them leave here, Haru's future is much greater than that of the two goblin merchants.

"All this is because of that human and the human tower master, Haru got the opportunity to change his destiny!" Sulu and Nulu said more than once.

But they also know that if they want to have achievements like Haru, they must hold Han Dong's thighs tightly and try their best to show their value.

Francis in the distance led the Nightmare beast and looked at the Nightmare Tower, and a look of worry appeared.

He could feel that Han Dong was doing something very dangerous at this time, but Han Dong could only bear this danger alone, and he couldn't help.

As if feeling the impatientness and uneasiness in Francis' heart, the Nightmare Beast lowered its head, stretched out its rough tongue, gently licked Francis's first picture, comforting his master.

Francis patted the nightmare beast's back, turned his head, and looked towards the west of the tower.

"If it weren't for the Spring of Life, if it weren't for the three large evil tribes that protected the Spring of Life, the master wouldn't have done such a dangerous thing..." Francis said in his heart.

"I would have been stronger."

At this moment, Francis suddenly felt that his originally strong spiritual realm seemed to be loosened a little. If it were in normal times, Francis could not detect such subtle changes. However, today, Francis noticed that the originally chaotic sea of ​​consciousness began to slowly shrink.

"Am I going to break through?" Francis looked at his hands, and suddenly there was a hint of expectation in his originally anxious heart!

I don’t know how long it took, but the door of the Nightmare Tower was pushed open, and Han Dong, with a tired face, walked out of the tower.

In his hand, he was holding a bottle of light green potion tightly. The potion was like a cloud of mist in the crystal bottle, constantly changing its shape.

"Master, you have successfully refined it!" Haru said excitedly.

Haru knew how difficult it would be to refine such a potion, so he also understood the chances of refining it successfully at one time. In its opinion, this was simply a miracle.

Han Dong smiled and nodded at Haru, then turned his head and said to Francis: "Francis, let's accompany me to the west again, let's move back that spring of life."

"As for the order, great master, your followers will always follow your steps!" Francis beat his chest with his left hand and gave a knight salute to Han Dong.

Han Dong also sat behind Francis with the strength of the nightmare beast Birut and carrying the two of them at the same time, he would not feel too much pressure, but he was just a little uncomfortable.

Han Dong also felt a little embarrassed when he hugged Francis' waist.

"It seems that I must get a mount in the Nightmare World as soon as possible. Otherwise, I would ride with Francis every time I rush to the road. Where can I put my master's face?" Han Dong said in his heart.
Chapter completed!
