Back at his chief's house, Zhang Yang put the gems and pet eggs in the warehouse. Looking at more than a hundred gems, Zhang Yang was still very happy.

The pet egg Zhang Yang has already posted it almost, but this time, another batch has been available and it will be used for a while.

Taking back what he needed, Zhang Yang directly learned about "setting up" and "roadblocks" and "spreading stone towers", but he did not look at it, but went out of the house and came to a corner of the tribe. When he saw no one, he directly used a special NPC card.

After a ray of light, a middle-aged man appeared. He had scars on his face and his hair was a little messy, but he looked bright and a shovel hung behind his butt.

The engineer's shovel is naturally composed of a piece of wood and a thin piece of stone, which looks a bit short.

"Did you summon me?" As soon as the npc appeared, he said to Zhang Yang that even if there were other players there, he would not pay attention to it. He still knew who summoned him.

"Yes, I want to learn double installation." Zhang Yang said.

"Okay." After saying only one word, the npc disappeared, as if it had never appeared before, but Zhang Yang was so happy that he was almost crazy because a posture scroll had appeared in his backpack, and he didn't even read the introduction, so Zhang Yang clicked to learn.

At this time, Zhang Yang smiled foolishly and called out the skill interface and started to look at it. He first turned on the "settings" that normal engineers would have.

Pose erecting: Level 0, 0 skill points can be used, and 1 fortification can exist at the same time. (For every level of upgrade to the installation, 1 skill point will be added to the following skills, and 1 skill point can be freely allocated. For every level of upgrade to the installation level, 1 fortification can exist at the same time. This posture level cannot be higher than the character level.)

Roadblocks (level 0, set up time for 5 seconds, cool down for 5 seconds, exist for 10 minutes, consume 1 tool box): Set up roadblocks to block the enemy on the ground, and the roadblock's blood volume is 10 points. (For every skill, the blood volume is 2.)

Spike Wood Tower (level 0, set up time 30 seconds, cool down for 1 minute, exist for 10 minutes, consume 2 tool boxes): Set up a rotating sppike Wood Tower that can attack the enemy on the ground, attack 0 and health 10 points. (Spike Wood Tower attack is 0% of the character's magic attack, and add 1% for every 1 blood added to the skill, and add 1% for the attack.)

Crossbow Tower (level 0, set up time 30 seconds, cool down for 1 minute, exist for 10 minutes, consume 3 tool boxes): Set up a tower on the ground that can emit crossbow arrows, attack 0 and health 10 points. (The crossbow tower attack is 0% of the character's magic attack, and every skill is added 1% of the blood, and attack is added.)

Stone-tree tower (level 0, set up time 30 seconds, cool down for 1 minute, exist for 10 minutes, consume 4 tool boxes): Set up a tower that can cast stones on the ground, attack 0 and health 10 points. (The attack of the stone-tree tower is 0% of the character's magic attack, and add 1% for every 1 skill to add 1, and attack 1%.)

Zhang Yang turned on "Double Setting" again, and the skills below are still the same. However, since there are two that have not been studied, the display is black, but the introduction of Double Setting has changed.

Double posture installation: Level 0, 0 skill points can be used, and 2 fortifications can exist at the same time. (For every level of upgrade to the installation, 1 skill points will be added to the following skills, and 1 skill point can be freely allocated. For every level of upgrade to the installation level, 2 fortifications can exist at the same time. This posture level cannot be higher than the character level.)

Along the way, Zhang Yang did see a lot of skills and equipment he needed, but as Bagao said, it was too expensive. Logically speaking, the things of engineers should not be so expensive. However, when Zhang Yang thought about it, he understood that there are not many equipment for 2 transfers now, and there are fewer occupations for 2 transfers. When everyone has 2 transfers and more equipment, everyone will find that the equipment of engineers cannot be sold at all, and at that time it will naturally be cheaper.

"Engineering weapons, take a look. Engineering weapons have the best weapons. Buy one free one. I regret not seeing them."

Zhang Yang heard this voice, especially the keywords, but he did not stop, but walked forward a few steps, mixed in the crowd, and then looked back as if nothing had happened and found that there was indeed a weapon on the stall.

From a distance, this is a hammer-like weapon. This weapon is a little shorter than a shovel, but it looks heavier.

Without going directly, Zhang Yang came to the stall next to him and squatted on the ground and looked at it. There were seven or eight items on the stall, most of which were level 10 equipment and two first-order weapons, which were not what Zhang Yang needed. However, Zhang Yang still asked: "Friend, how do you sell this weapon?"

"2 gems, this is a powerful weapon of 1 turn, a good thing." The man replied.

Zhang Yang shook his head and said, "It's too expensive, just a gem, and then buy one free. A booth next to you also buy one free one free?"

A 1-turn weapon costs only 2 gems, which shows how fooled Zhang Yang was in the past.

"1 gem? You can buy one free one?" The man was stunned, and then said dissatisfied: "Friend, you'd better go to this store to see it. He buy one free one free one, I can't afford it." As he said, the man pointed to the stall next to him, looking very impatient. Now there are more and more tribes. Seeing that everyone's level has risen, this thing will definitely not be worried about selling.

The owner of the stall next to him immediately became interested when he saw Zhang Yang and the others talking like this: "Yes, the boss will come and have a look. I'll buy one and get one free."

Zhang Yang said, "If you don't sell it, then I'll go to the place I bought." After that, Zhang Yang moved to the stall next to him in anger. When he saw the items on the ground, Zhang Yang's eyelids twitched.
