Building infrastructure in a digital world

Before these ghost skeletons were attracted, Su You had already killed the first ghost skeleton.

This was the attack method that the two of them had discussed before. Doya, who had better archery skills, would attack the ghost skeletons behind Lake to attract them, and then Suyou would deal with it.

This will not only prevent Lake from being chased for too long and consume too much of his physical strength, Su You can also avoid wasting her own output without accidentally injuring him.

After the first batch of ghost skeletons were all dealt with, Lake ran back with the second batch of ghost skeletons... and so on, until the fifth batch of ghost skeletons was pulled to the arrow tower and was captured by Duo Ya and Su You With the kill, it's all over.

……

At the moment when the last ghost skeleton was killed, Lake sat down on the ground with no image, sweating profusely and panting.

Su You knew how tired he was. After all, he ran at the highest speed for a total of more than ten minutes.

The most important thing is that he not only has to run, but also has to pay attention to all kinds of situations around him at all times, so as not to be stalked. Normal people definitely cannot bear such a high amount of exercise... Lake is also a normal person, and he can't bear it either, but He had the potion of agility given by Su You, so he managed to hold on, otherwise he would have been lying down seven or eight minutes ago.

Su You knew how tired he was, so she didn't bother him to rest. She just asked Duoya to help deliver food and water to replenish her strength, and she took the time to go behind the stone gate and pick up the black stone.

Afterwards, Su You walked around the stone gate, groped for a while, and finally put the black stone into an inconspicuous groove in the stone gate.

The moment the black stone was put into the groove of the stone gate, Su You received a reminder that the stone gate was sealed——

[Do you want to seal the ghost stone gate? 】

[Reminder: During the seal period of the ghost stone gate, the ghost skeleton will not stop refreshing, but the refresh rate will be reduced by 30%. During this period, the ghost skeleton refreshed will be locked in the ghost stone gate and cannot leave. The ghost skeletons generated during this period will escape from the ghost stone gate. 】

Sure enough, it was the same as before.

Su You's eyes flickered slightly, and then she pressed down the black stone in her hand forcefully, expressing her choice with practical actions.

[The ghost stone gate has been sealed, sealing time: 120 hours. 】

After successfully sealing the ghost stone gate, Su You breathed a sigh of relief, then looked around, ready to see if there was anything else.

But no matter how she looked at it, there were only flowers and trees around here, and there was nothing else of value.

Su You was not disappointed either. After all, she didn't expect anything. When she returned to the vicinity of the Arrow Tower, she began to pick up the ghost skeleton's drops on the ground.

[Get Copper Coin*35]

[Get Copper Coin*17]

[Obtain unknown bones*6]

[Obtain scale powder*43]

……

There are only three main drops from ghost skeletons, one is copper coins... Needless to say the role of this thing.

The other two drops are 'unknown bones' and 'scale powder'.

From the appearance, this 'unknown bone' is actually similar to a bone stick. Its main function is that it can be made into something called 'bone meal', and bone meal is one of the raw materials for 'fat production'.

Birth-promoting fertilizer, literally, is used for crops, which can reduce the growth time of crops.

The more advanced the crops, the worse the effect of the fertilizer, and the use of the fertilizer for each plant is not unlimited, but has an upper limit.

Under normal circumstances, a plant can only use the growth fertilizer five times.

In addition to making bone powder to synthesize fertilizer, bones also have some other functions, such as making bone spurs (weapons), bone sticks (weapons), and some decorations with weird shapes, such as skull vases, skull ornaments, Skull desk and more.

As for another material, scale powder, this is a white powder that is soluble in water and is a common alchemy material.

When it comes to alchemy, we must talk about the difference between it and alchemy... The most obvious and easy-to-understand difference between the two lies in the difference in raw materials.

The raw material of refining medicine is herbal medicine, and the dosage needs to be cautious, and the process should also be careful. There must be no mistakes in the slightest, otherwise it will fail. If it just has no effect, it’s okay, and some people may even make good medicines for curing diseases and saving lives. A deadly poison.

Alchemy is different.

The raw materials for alchemy are various. Except for scale powder, any item can be used as a material for alchemy, such as berry plants, herbs, ores, animal skins, animal teeth... All kinds of messy things can be used as raw materials.

In the field of alchemy, it can be said that all comers are welcome, and there is no taboo.

'There are only materials that cannot be obtained, and there is nothing that cannot be refined', this sentence is not a joke.

Of course, what can be refined is what can be refined, but without a correct formula, what can be refined... then it is unknown.

Su You does know about the alchemy formula of scale powder. With scale powder as the main material and some other auxiliary materials of the same nature, it can be made into a transparent solution.

Applying this solution on the body can make the body covered with a thin film, which is similar to the almost invisible body of the ghost skeleton, which is a common concealment (non-invisibility) prop.

……

After cleaning up everything on the ground, Su You took out the remaining materials in the backpack and prepared to continue to arrange defensive measures-this was the preparation for the release of the seal in five days.

Although Su You had already recruited Meke at that time, and would bring him over to deal with these ghost skeletons, this was just her plan, and the plan could not keep up with the changes. There were too many, so she had to make a few more preparations.

While Su You was setting up the defensive measures here, Lake was almost resting, so he came to ask Su You if he had any orders. Seeing Su You shaking his head, he went to the mine to continue digging stones.

Although he didn't bring a pickaxe on this trip, Su You, the place where the mine is often used for mining, has built a wooden box, which is specially used to store the things Lake needs for mining.

For example, mining picks, whetstones, basic healing potions, and some small amounts of food, but definitely enough for him to eat for two or three days.

In addition, there is also a wooden cart docked at that location, which is specially used by Lake to transport stones.

After Lake left, only Su You and Duoya were left in this place.
