In half an hour, Lu Ren communicated with all NPCs in the novice village, and successfully received several high-level tasks in the name of the village chief.

Most of these tasks are about hunting demonized monsters, all located in the northern region, including monsters from level 10 to level 15, and collecting special items.

Before setting off, Lu Ren carefully checked his backpack and found that there were already a lot of extra things in it.

First, he bought five bottles of mana-restoring potions for fifty copper coins, a bundle of tens of meters long fuses worth five copper coins that could be ignited, and finally two bottles of very expensive special potions.

[Concealment Potion (Low Level)]

[Quality: black iron]

[Special effect: Within ten minutes after use, you will be protected from active attacks by monsters. It will be automatically released after the attack. The monster level cannot exceed level 10. 】

[Introduction: One of the products of the professional "pharmacist", the principle is to cover one's body with the breath of monsters, making the monsters think that they are the same kind, but it cannot cover up the detection of high-level monsters. 】

The price of a bottle of concealment potion was as high as 50 copper coins, and the two bottles added up to one silver coin. Although the price was not cheap, Lu Ren still bought it resolutely.

In Lu Ren's opinion, such a potion is definitely worth it. Even if it is used when being chased by monsters, it can directly escape danger. The only drawback is that the level limit is too large. In the entire Novice Village,

At most, it can only affect monsters like demonized chickens.

However, this is enough.

"It's a pity that I didn't get any information about this thing." Lu Ren looked helplessly at the "lost wedding ring" in his hand, threw it into his backpack, took out the map again, and observed the terrain.

"The breeding farm, if this place is used..." After Lu Ren chuckled, an idea appeared in his mind. He changed his course of action and headed to the mine.

There were no monsters along the way, and the mine was not far away. Lu Ren quickly arrived in front of the mine, but the mine had been blocked at this time, and the roars of monsters could be heard from time to time.

.

Outside the mine, there was an NPC named "Miner Zhang" standing. Lu Ren quickly went up and asked: "Why is this place blocked?"

"It's not because of those demonized creatures." Miner Zhang said in a complaining tone: "Now the entire mine cannot be opened unless all the demonized creatures inside are removed..."

"That's it..." Lu Ren frowned and said, "But now I'm in urgent need of some minerals, what should I do..."

"If necessary, I still have some inventory here!" Miner Zhang's eyes suddenly lit up and he said quickly: "Although the original employer thought these minerals were contaminated... I assure you, there is absolutely no problem!"

"Can you show me first?" Lu Ren smiled.

A store opened in front of Lu Ren's eyes. It was marked with various minerals, such as diamonds or gold and silver, as well as some things that could not be seen in reality. These were all used as forging materials.

Lu Ren definitely doesn't know how to forge now. It's useless to get more of this kind of material, but he looked at the bottom of the store, and there was also a very cheap material, large stones, all of which were one meter in diameter.

"This is it." Lu Ren checked the price and found that he only needed 1 silver coin to buy a set of 99 pieces, so he bought two sets.

After the transaction was completed, there were two more sets of large stones in Lu Ren's backpack, occupying one-tenth of the only 20 spaces in the backpack, but he did not feel any extra weight.

"These are enough." Lu Ren ran toward the northern area with these rocks that were too heavy to hit anyone, forged garbage, and were heavy enough to be taken out.

Soon, Lu Ren used his current high agility to arrive at the territory of the demonized chickens. Some buildings scattered the chickens. Among the buildings, the most conspicuous one was a seventeen-year-old chicken.

, an eight-meter-tall windmill.

However, no matter how conspicuous they are, they are not as eye-catching as those little chickens. Each of these demonized "little" chickens is more than one meter tall. Their claws are like steel knives, and there are black spots visible to the naked eye around their bodies.

Damn, it looks scary.

"That's high enough there." Lu Ren looked at the windmill, took out the fuses and explosives, and tied them together to detonate the explosive remotely.

Then, after Lu Ren walked around for a while and learned about the current branches of all the demonized chickens, he made up his mind. What he had to do was to climb to the top of the windmill!

What's more troublesome is that the entrance under the windmill has been completely sealed. A pile of rocks is piled outside the door, and there are dozens of chickens wandering around. Even if both bundles of explosives are used, it is impossible to break through.

.

This is why Lu Ren wants to buy so many stones. His method is very exaggerated and extreme, that is, climb up from the outside! Directly to the top of the tower!

Lu Ren first took out a bottle of concealment potion. After using it, he tried to get close to a demonized chicken. The latter seemed to be aware of him, but did not make any move to attack.

"It really works!" Lu Ren said secretly. He seized the time and ran towards the place where the windmill was. He chose a place with the smallest number of demonized chickens and took out a stone from his backpack.

A huge stone appeared in his hand, which was taller than half his body. With his current strength, it was impossible to lift it. With a loud "bang", the stone was smashed to the ground.

Lu Ren took a step back, took out a stone again, placed it on the ground, then climbed up, and placed a new stone on top of the stone in front of him.

In this way, a "staircase" with a height of two meters is formed. This is also the approach taken by Lu Ren. As long as he uses the same method at the rear and puts down more stones, he can climb to the top!

As for the number of stones that need to be used...it is actually just a very simple difference in the equal sequence, the formula sn=na1+n(n-1)d/2. After a little calculation and calculation, you can get the number 153.

There are 45 extra stones.

But the biggest problem with this method is that it cannot be affected on the way, there is enough free length behind it, and it must maintain good balance.

The first point has the help of the concealment potion, so there is no need to consider it. The site here is a plain, so there is no need to worry about the second point.

The most important thing is only the third point, and this will test Lu Ren's skills. This is his first time doing this kind of thing (not many people have done it), so naturally he has no experience to talk about and can rely on.
