At least four corners of the house should be placed in the four corners of the south, south, north and west, with fixed crossbows with red gems.
And let their arrows face, either clockwise or counterclockwise.
This can form a chain of arrows, at least lock the invasion angle of the ground monsters.
You also need at least three red gems, which is 3000 pieces of wood.
There are still more than a thousand virtual coins in Tang Zheng's pocket, and even if they are thrown away, they can only buy more than [-] pieces of wood at most.
But in case there is an urgent need to use virtual currency, it is very unsafe.
It is still mainly mining, and finally see how much wood is missing, and then buy it.
The area of the wetland forest is very large, and the area where Tang Zheng is located belongs to the depths of the forest, surrounded by endless trees.
Moreover, every time Tang Zheng is mined, the seeds dropped from the trees will be replanted into the soil.
In this other world, not only vegetables and fruit crops grow fast, but trees grow many times faster than in the native world.
There is no shortage of wood, but it takes time to collect.
While cutting wood, throw dense wood into the crafting table to make planks.
Tang Zheng mobilized all the staff to cut wood, and even Xiao Ye cooperated to pounce on the trees, but its efficiency was just average.
In a blink of an eye, it was noon.
In the morning, with the automatic logging device, Tang Zheng had already stocked up the materials for the second red gem.
Without further ado, he threw it directly into the melting table.
The red gems produced were installed on the second fixed crossbow.
Take a short nap, after a simple lunch.
Tang Zheng was just about to get up and continue logging.
Suddenly he heard Lan Lan calling out to him from behind.
"Master, the talent I refreshed just now is an S-rank mechanical improvement talent. I wonder if I can help?"
The 5th-level SSS-level talent magic will refresh periodically every 12 hours.
This time, a talent related to machinery was actually brushed out, causing Tang Zheng to pause slightly before turning back.
Lan Lan took advantage of the situation and opened the light curtain to show him.
S-class mechanical improvement can improve any machine, but it requires enough raw materials.
This is a talent that is said to be strong or not, weak or weak.
It's a bit tasteless now, and many players can't even make bronze, let alone mechanics.
But looking to the future, improving machinery is a magical skill that can rival SS-level talent.
Tang Zheng thought for a while, but felt that this talent was useless.
The main reason is that Lan Lan did not open the hidden mechanism and did not enter the semi-industrial era.
The machinery transformed by her hands has no special attribute bonuses.
Only relying on the initial 5 points of mechanical strength, I am afraid that blocking the first wave of monsters is not a fool's dream.
Tang Zheng shook his head at Lan Lan and raised his axe just as he was about to leave.
Suddenly, a light flashed.
As if thinking of something, he took a few steps back.
"Lan Lan, can you understand this thing?"
He unfolded the light curtain and clicked on the synthesis stage.
The blueprint production steps for fixing the bow and crossbow were shown in front of Lan Lan.
The tedious blueprint steps, if there is no synthesis table, it will be very troublesome to assemble a crossbow.
But Lan Lan only glanced twice, but frowned slightly, stretched out her white and slender fingers, and tapped a dozen locations on the light screen in a row.
"The gear structure here is a bit redundant. If this gear can be made one larger and the other smaller, the efficiency will be faster, and the position of two gears can be saved."
"The tenon-and-mortise structural board over there is obviously at the wrong angle. In order to support this angle, we need to use three more pieces of wood. It can be changed to this combination."
"The position of the quiver can be expanded, and the bow and arrow itself can also be increased by a lift angle like this, so that it is not limited to shooting in the horizontal plane."
"The last is the blueprint of the entire construction. It's too cumbersome. There are many unnecessary steps. I feel that at least 60 steps can be improved."
Some professional words were constantly spit out from Yingfan's small mouth. At this time, Lan Lan didn't look like a primary school girl at all.
instead like
Kudo Shinaran, whose body is smaller but still has a clear mind!
After the little girl finished talking, when she looked at her master again, she found that he was staring at her like a monster.
"Is there anything wrong with what Master Lan Lan said?" Lan Lan felt a little guilty.
After a few seconds of silence, Tang Zheng suddenly picked her up and turned around.
