Shui Sheng and Zhang Zibing grinded for a long time and finally grinded out a large bag of raw ore powder. Xu Feng took the big bag and nodded with a smile: "It's done, you guys wait for me here!"
After saying that, Xu Feng quickly entered the portable secret realm with this large bag of materials.
Xu Feng quickly walked to the alchemy furnace in Yizhuang and put the five materials into the furnace one by one.
"It's a pity that we don't have special alchemy tools, so we can only make do with this alchemy furnace..." Xu Feng thought to himself.
Whether it is alchemy or alchemy, the processing of materials is nothing more than refining and extraction. Each subsequent refining has its own method. Xu Feng does not have alchemy tools, so he can only make do with an alchemy furnace. A spiritual-level alchemy furnace can process some ores.
There is no problem with the materials. After all, the raw materials of some elixirs also include ores and metals.
The flames were blazing, and the five ore materials in the alchemy furnace began to slowly change under the burning fire. The original pile of powder began to melt slowly, gradually becoming viscous, and the impurities slowly separated from the alchemy furnace.
It flows out from the diversion port. These are impurities. If they are not cleaned up, erysipelas will appear during the alchemy process and the quality of the elixir will be reduced!
Soon, all five ore materials were extracted and quenched, two of which were still in powder form, and the other three turned into viscous liquid.
After taking out the five refined materials from the alchemy furnace, Xu Feng disappeared in a flash.
"The materials have been refined. All that's left is to stir them together and let a mechanical creature swallow them first!" Xu Feng began to stir and mix the five refined materials.
"It's a pity that if you know how to do alchemy, you can make real rust poison. The current one cannot penetrate the alchemist's eyes at all. The rust effect is not even one-tenth as good as the genuine one, but the core principles are the same. It's just that
I'm afraid it will take a longer time to take effect..." Xu Feng explained while making it.
Soon, Xu Feng made a copy of the rust poison. Xu Feng was not sure how effective this simplified version of the rust poison would be, so he could only try it out.
After catching the two mechanical fish that Shui Sheng and Zhang Zibing had caught before, Xu Feng poured the newly made rust poison into their mouths bit by bit, and then threw the two mechanical fish into the upper reaches of the river.
All you have to do is wait patiently.
One minute, ten minutes, half an hour, an hour...
Time passed little by little, but there was nothing strange in the river. There were only less than two hours left before the main mission was completed.
Shui Sheng glanced at Xu Feng secretly and sighed in her heart. It seemed that this promotion mission was going to fail.
"What kind of rust poison, it sounds unreliable at first glance..." Shui Sheng muttered in a low voice.
At the same time, the two mechanical fish in the river, the moment Xu Feng threw them into the river again, began to emit gray-brown powder particles, and their movements also became distorted.
Any mechanical creature contaminated by rust poison will become a source of poison, and its body will become a nutrient for the rust poison. As the body is corroded step by step, the rust poison on the body will slowly dissipate, looking for nearby machinery.
Life, contamination, erosion, decomposition...
The poison of rust is like a fire in the forest. Once it burns, it will be unstoppable and destroy the entire forest.
It's just that the rust poison made by Xu Feng is not the genuine rust poison. If it were the rust poison made by an alchemist, only one drop would be enough to kill all the mechanical life in the entire river in a short time.
The two mechanical fish that had swallowed the rust poison persisted for more than half an hour before they finally turned into a ball of rust and sank to the bottom of the river. At the same time, the rust poison escaped, killing more than a dozen mechanical life forms around them.
Contaminated with this poison.
These mechanical lifeforms, which are contaminated with the poison of rust from the surface of their bodies, corrode at a slower rate. Standing on the river bank, you can't see anything strange, but in Hanoi, these mechanical lifeforms have become a mess.
Although for mechanical life, they don't know what panic and fear are at all, but this kind of situation where the body is slowly rusting and there is no way to resist it makes all mechanical life feel that a disaster is coming. Many mechanical life have detected that there will be danger in the upper reaches of the river.
There was a glimmer of hope, and they all rushed upstream. However, when passing through this area, they were inevitably contaminated with the poison of rust, so these mechanical lifeforms carried the poison of rust and swam farther and farther upstream.
The poison of rust is like the tarsal bones. Once it is contaminated, it will completely rust from point to surface, unless the entire contaminated area is dug out, but the mechanical creatures in the river cannot do this.
An hour later, the mechanical creatures in the entire river were contaminated with rust poison, and more and more rust poison gathered around the invisible light curtain around the space transmission node, constantly corroding the light curtain.
defense.
After waiting for more than half an hour, Shui Sheng couldn't sit still.
"Is that rust poison of yours useful? How about we try to sneak in invisibly and attack with all our strength? Maybe we can break through the defense of the space teleportation node..." Shui Sheng's face was full of anxiety and worry.
look.
"It's useless. Why do you think there are so many mechanical creatures here?" Xu Feng shook his head and said: "The invisibility charm can only hide our body shape, but the temperature and smell cannot be hidden. As long as we go in, those mechanical creatures will be very...
It’s easy to detect us!”
"If you don't believe me, ask Zhang Zibing, do they have such a method?" Xu Feng shrugged and said.
Shui Sheng turned to look at Zhang Zibing. Zhang Zibing sighed, nodded and said: "These are the most basic detection methods. Every mechanical creature has them. Not only these, even illusions are useless to them. They can detect
All illusions..."
"Then let's..."
Before Shui Sheng finished speaking, Xu Feng stood up and looked towards the river not far away, with a look of joy on his face.
The simple version of rust poison that Xu Feng refined was actually used by almost every secret realm apostle in the previous life. When encountering mechanical creatures that he could not deal with, he would refine some to reduce the difficulty of attacking. The disadvantage is that it is weak in toxicity and slow to take effect, but it is useful.
It is indeed useful, so Xu Feng is still very confident.
"Look, the rust poison has taken effect!" Xu Feng pointed at the river and shouted.
At this time, a trace of gray-brown floated on the rolling river. This gray-brown color became thicker and thicker, and soon became larger and larger. It soon covered a large area, and as the river continued to flow downstream, it became
The entire river was shrouded in gray-brown.
From the time gray-brown appeared until the entire river was shrouded in gray-brown, more than half an hour had passed, and it was less than an hour before the main mission ended.
"Shui Sheng, go and have a look in the river again!" Xu Feng shouted loudly.
Shui Sheng also had a look of joy on his face. He quickly took out a piece of paper talisman, folded it a few times, threw it away, and turned into a bird and rushed towards the river.
Soon, the bird turned into a small fish and fell into the river. The scene in the river suddenly appeared clearly in the minds of Shui Sheng and Xu Feng.
