For the task of destroying the space node, no matter what, being able to find the mission target first is half the task. The next step is to find a way to destroy the mission target.

"Let me try the defensive power around the space transmission node!" Shui Sheng said in a low voice.

The vision in Xu Feng's mind began to rush towards the space teleportation node rapidly. When it was one foot away from the space teleportation node, suddenly a translucent light curtain appeared, blocking the Fu Yu outside and preventing it from getting close.

The next moment, light golden runes lit up on the surface of the talisman fish, and it exploded with a "bang", splashing river water more than two meters high. Xu Feng's mind suddenly went dark, and he completely lost sight of the talisman fish.

However, before the Talisman Fish exploded, Xu Feng had already "seen" that the defensive strength of the light curtain surrounding the space transmission node was also extremely strong, and the power generated by the Talisman Fish explosion was not enough to shake it.

"It's just like the fake one in the Iron Fortress. There are defense facilities around it. And the defense here is probably much stronger than that in the Iron Castle..."

“Trouble…”

"Moreover, the mechanical creatures around here are larger and more powerful. Since the Talisman Fish has no entity or flesh, it can get close. If it were us, we would probably be attacked by those mechanical creatures if we got close to the shore..."

…

Xu Feng and Shui Sheng discussed for a long time but could not come up with a good solution. If they were in the Golden Plains, the two of them could lure out the mechanical creatures protecting the space transmission nodes little by little and kill them, but in the river, this method would not work.

"It's a pity that they are all mechanical creatures, otherwise, I would poison all these bastards to death!" Shui Sheng waved the wooden sword and chopped fiercely at the surrounding weeds.

There are less than three hours left until the main mission one. Once the mission is completed, I don’t know if I can continue to stay in this secret world. If not, I’m afraid everyone will fail in this advancement.

"Those people in Alfak City are not at a disadvantage. That's just a false target. Even if they rush in, they can't complete the main mission..." Shui Sheng said with a bitter look on her face, "We are really at a disadvantage. We know where the correct target is, but we can't destroy it. We are really only half a step away from promotion. We are unwilling to accept this!"

"Ah~" Shui Sheng screamed madly, with a look of unwillingness on her face.

"You, what did you just say?" Xu Feng seemed to have thought of something, a light bulb went off in his mind, and he asked subconsciously.

"I said we are losing a lot!" Shui Sheng shouted.

"No, the previous sentence!" Xu Feng shook his head.

"If they are not machines, we..." Shui Sheng seemed to realize something, a look of surprise appeared on her face, she turned her head, stared at Xu Feng and said: "Do you have a way to poison those machines?"

In his previous life, Xu Feng had encountered many mechanical creatures. These monsters had high defense and resistance. With sufficient ammunition, each ordinary-level mechanical creature had strength that was no weaker than other biological elite BOSSes, and was very difficult to deal with.

In the list of monsters that the secret realm apostles hate to encounter the most, mechanical creatures can be ranked in the top five. However, there are ways to hunt these monsters.

There was once a secret realm apostle who was an alchemist. He studied a chemical agent called Rust Poison. This Rust Poison was not a single agent, but a series of agents. Depending on the material and the mechanical creatures encountered, different types of Rust Poison were required.

Therefore, the use of Rust Poison is very cumbersome. Except for the sensation it caused when it first appeared, few people use Rust Poison anymore.

Unless you are faced with a BOSS among mechanical creatures and all other means have failed, you will only think of using rust poison!

"Shui Sheng, you and Zhang Zibing go and capture two mechanical creatures. It doesn't matter how strong or how big they are, just capture two of them at random!" Xu Feng ordered, "I'll go get some materials!"

After saying that, Xu Feng’s figure flashed, and he slowly disappeared from the spot, entering into the secret realm he carried with him.

Entering a portable secret realm in a secret realm is a very dangerous thing, and it is easy to be assimilated by the secret realm. But Xu Feng no longer cares about these at this time. After entering the portable secret realm, he rushed directly towards the ogre mine.

At this time, in the kobold mine, in addition to a zombie miner, there were also two murloc miners who worked hard every day to collect ore under the command of the kobold supervisor.

At this time, a lot of raw ore had been piled up in the kobold mine.

Seeing Xu Feng rushing into the mine, the Kobold Supervisor rushed over to him. Just as he was about to speak, Xu Feng immediately waved his hand to interrupt him and ordered, "Give me one piece of each type of ore you collected, quickly!"

"Yes, master!" the kobold overseer responded immediately.

Three miners and a kobold supervisor quickly sorted the ore. Because taxes had not been collected for three months, a lot of ore had accumulated in the mine, but most of them were the most common iron, copper and tin ores.

There is no wrong version in the 1619 book forum!

Soon, more than a dozen kinds of ores were placed in front of Xu Feng. These were the raw ores that had been collected recently. Xu Feng didn't even look at them. He collected all the ores directly, and with a flash of his figure, he left the secret realm.

Xu Feng threw all the ores that he had pocketed in his clothes onto the ground, took out the "Tearing Tooth", and began to grind the ores into powder bit by bit.

Because Xu Feng is not an alchemist, even though he knows how to make rust poison, the effect of the rust poison he made is probably less than one-tenth of the real rust poison.

But this is the best solution he can think of!

Just as Xu Feng was cutting and grinding the ore, Shui Sheng and Zhang Zibing came over, each holding a mechanical fish.

Looking at the two lively mechanical fish, Xu Feng began to use the powder of the raw ore to mix it. It took more than half an hour. Xu Feng mixed more than a dozen portions of rust poison. Some of the rust poison was in powder form, and some was a viscous liquid.

Xu Feng applied the rust poison to the two mechanical fish one by one, observed the changes in the reactions, and finally selected the one with the best rust condition.

"This is it!" Xu Feng picked out five pieces of ore from a dozen pieces and said, "Grind all these ores into powder, and leave the rest to me. As long as I have enough rust poison, I can kill all the mechanical creatures in this river!"
