After level 20, the upgrade speed has slowed down significantly. The most intuitive manifestation is that the 5 people of Zhang Yang reached level 21 until the 12-hour limit this time.

The upgrade of posture doesn't seem to be fast. Zhang Yang's posture has just reached level 10 without practicing setting and only practicing double setting.

Zhang Yang summoned everyone to sit down and gather together.

"We are all at level 21, so we can go to brush the dungeons." Zhang Yang said: "This giant rat copy is a level 10 dungeon, but there are 5 difficulties. Each increase of difficulty is equivalent to increasing the initial difficulty by 1 times. The most difficult nightmare difficulty is equal to 5 times the initial difficulty, and the consumption is also increased in this way. So I want to first try to brush the normal difficulty and adventure difficulty by myself, and then open the permission of King of Difficulty, and let us go in together, which can save a lot of challenge scrolls."

After hearing this, the few people frowned. Zhang Yang said it very clearly. The difficulty increased by 1st level, and the difficulty of the monster also increased. This is similar to the level of the equipment. It seems that the increase is smaller and smaller as the base is already large enough, so the improvement is still very terrifying. Zhang Yang himself can deal with ordinary difficulties, but can he deal with the difficulty of taking risks?

The comparison between the difficulty of adventure and the difficulty of ordinary adventure is directly doubled, which is equivalent to the ability of the monster inside being doubled. Can Zhang Yang be able to do it alone?

Seeing everyone's worries, Zhang Yang smiled and said, "Don't worry, there will be no problem. I'll go in and check out the copy route first. You can level up here first and wait for my news." Zhang Yang stood up.

When they talked here, everyone naturally would not speak more. But they remember that when Zhang Yang was experiencing experience before, he boasted that when he reached level 20, he would definitely let them experience the feeling of experiencing experience. I think Zhang Yang now should be what he said, "It's time."

He did not use the return book. Zhang Yang flew back to the tribe while sitting in a vulture. Zhang Yang and his friends knew the value of returning book, so Zhang Yang did not need to say much about this matter.

After cleaning up his backpack, Zhang Yang took out a challenge scroll, and then came to the portal next to the bonfire, and a virtual screen appeared.

There are two ways of transmission shown above. The first is "destination", and there are no options in it. The second is a copy. Zhang Yang opened it, and an option appeared in it, which is also the only option.

"Giant Rat Copy (normal login): Level 10 copy, tribal member transmission fee is 1, is it transmitted?"

Below this dungeon, there are some equipment and weapons items that may fall off of the dungeon, which is an attractive way.

The transmission fee was set by Zhang Yang himself, and the minimum unit was 1 yuan, so he had no choice. Fortunately, some of it will become taxes here.

If you log in to the exclusive copy in the future and there are special items in it, then Zhang Yang can set a higher teleportation fee, such as 100 tribe members once, and 150 people outside fall once, and taxes will come in.

“Telection.”

The virtual screen changes, the options for the Giant Rat copy become larger, and the difficulty selection appears below, and the instructions for consuming the challenge scroll.

Zhang Yang has not made this dungeon, so he can only choose the lowest level "normal" because it is a level 10 dungeon, so the consumption is 1 challenge scroll.

After confirming again, the scene changed and the "time and space tunnel" appeared again. A few seconds later, Zhang Yang arrived in a cave, and the map also automatically appeared in the void.

The layout of this dungeon cave is obviously different from that of the Giant Rat Cave. There are only three forks, and each fork can lead to the last boss room.

Zhang Yang took out four tool boxes and threw them directly on the ground. A phantom of a stone casting tower appeared, with many points that needed to be knocked on it. Zhang Yang started to knock with a hammer. After half a minute, a stone casting tower was built.

The stone casting tower looks as tall as two people, and is made of stone and wood. At the top of the tower, there is an tilted mouth, and a large stone lies quietly inside.

Zhang Yang was a little excited. This was the first time he had built his own stone casting tower in his life, so he couldn't help but look up and look again and even touched the cold stone casting tower's body.

It took a long time before Zhang Yang calmed down. He smiled. If his behavior was seen by the bake, he would definitely laugh at me, he thought.

Zhang Yang level 21, the attribute points continue to be added to magic, and there are also purple weapons, so the magic attack became 71-128.

The posture is also level 10, and 10 skill points are naturally added to the Stone Cat Tower, so the properties of the Stone Cat Tower are:

Stone-treating tower (level 20, set up time 30 seconds, cool down for 1 minute, exist for 10 minutes, consume 4 tool boxes): Set up a tower that can throw stones on the ground, attack 14-25, and health 30 points. (The attack of the stone-treating tower is 20% of the character's magic attack, and add 1% for every skill 1 blood, and attack 1%.)

Zhang Yang knew that the stone thrown out of the stone tower was considered a magic attack, and the attack damage was changed by his own magic attack. The attack of 14-25 did not seem to be high, which is just a novice with a 1-turn. But don’t forget that Zhang Yang has doubled the setup. The level 10 posture can already set up 2 fortifications, and Zhang Yang can set up 4 units. If 4 units attack together, it will be similar to Zhang Yang’s own attack. Although the frequency is much slower than his own attack, it can’t stand it endlessly.

So this ordinary copy is not difficult for Zhang Yang at all. As long as you pay attention to not being surrounded by monsters, there is no danger.

After thinking about this happily, the cooling time just came. Zhang Yang set up a stone casting tower and walked towards the middle passage. After walking a few steps, a large number of monsters were refreshed in the open space and rushed towards Zhang Yang with his teeth and claws. Zhang Yang quickly retreated and came to a place where both stone casting towers could hit, and then turned around.

These monsters are giant rats at level 8 and do not pose any threat to Zhang Yang's stone casting tower. It's just that when two monsters attack the first stone casting tower, the stone casting tower cannot attack the monster and can only kill blood.

The attack distance of the stone-tower tower is about 15 meters. Zhang Yang walked along the way and set up a stone-tower tower every 10 meters to ensure that each stone-tower tower can attack another stone-tower tower, so that there will be no blind spots.

The monsters were refreshed very quickly, and Zhang Yang could only kill these little monsters before he could continue to move forward. After 2 hours, Zhang Yang arrived at the boss's room and saw the guy with this attribute.

"The King of Giant Rats (boss): Level 14, omnivorous animal, Qi and blood value of 1000/1000, unbeatable."

This guy looks exactly the same as the one outside, but also has the same attributes, and this is just the lowest difficulty copy.

Zhang Yang did not rush forward, but came to a gentle slope that looked taller, and then set up all four stone casting towers to form a square with a diagonal 15 meters. There is a stone casting tower at the four corners, which can ensure that any dead corner under the stone casting tower can be attacked by the other three stone casting towers.

An excellent engineer must not only be good at observing the terrain and know how to use the terrain to make profits, but also know how to place the fortifications to be the most effective.

Zhang Yang naturally doesn’t have to learn these again, so he saves a lot of trouble.

After walking a few steps forward, the boss immediately noticed the invader, howled and ran towards Zhang Yang. Zhang Yang naturally retreated quickly, retreated to the middle of the stone casting tower, and then ran around the middle, until the boss was attracted by a stone casting tower, and Zhang Yang looked bored.
