Global apocalypse, I have random discount stores

Chapter 49 Advanced Recipe Synthesis
After returning to his manor, Zhang Cheng made the fish he had just caught into food, then watered the wheat by the way, and then went into the house to rest.

The newly made luxury single bed is very comfortable, and Zhang Cheng has a good rest every night.

Two days passed in the blink of an eye. Zhang Cheng worked hard during these two days, and he did not leave any tasks or treasure boxes that he should do.

After two days, Zhang Cheng's current three levels:
[collection level 9]

[Production Level 11]

[Combat Level 12]

At this moment, Zhang Cheng was in the Wushan Mine. After Zhang Cheng activated the two skills of 'gathering enhancement' and 'gathering acceleration', as well as eating and gathering food, Zhang Cheng began to collect resources frantically.

At the same time, Zhang Cheng's collection experience value is also rising rapidly.

The backpack kept adding items, but fortunately, Fido was at the side, and Fido's backpack was about to be filled in a short while.

Half an hour later, Zhang Cheng's collection level finally reached level ten, and at the same time his backpack was filled with a lot of supplies.

Zhang Cheng returned with supplies.

After returning to the manor, Zhang Cheng first put the items in his backpack and Fido's accompanying bag into the locker of the manor, and then received a batch of materials made in the tool table.

【Obtain planks*100】

[Obtain stone bricks*50]

[Get hexagonal nails*10]

……

This batch of materials was prepared by Zhang Cheng to upgrade the third-level manor.

Now Zhang Cheng's lowest collection level has reached level ten, which meets the basic conditions for upgrading Sanzhuang.

And Zhang Cheng has been preparing for the materials needed to upgrade Sanzhuang these two days, and now he can finally upgrade the manor.

[Are you sure to upgrade the manor? (Estimated to take 10 minutes)]

"upgrade."

Following Zhang Cheng's order, the manor began to expand and change again like last time.

Widened foundation and farm, stronger-looking manor gate...

[The manor level has been upgraded to level 3, do you want to check the upgrade details? 】

Zhang Cheng Click to view.

[A new map has been unlocked - the polar ice field, players can go there by themselves through the helicopter entrance and exit]

[Unlocked formula blueprint - level 2 building strengthening material]

[Recipe blueprint unlocked - colorful crystal chandelier]

[Unlocked formula blueprint - vine branch wooden window]

……

[Unlocked formula blueprint - basic drone chip]

After the upgrade is successful, a large number of building structure formulas and household furniture formulas will be unlocked again, some of which Zhang Cheng will probably use. For example, building strengthening materials are very practical.

Among the major formulas unlocked by upgrading, the basic drone chip is the most critical.

The assistance of the drone in the player's survival will play a very important role. When the player upgrades to the third-level manor, the drone chip formula can be automatically unlocked.

Although it is only the most basic chip, it can at least allow players to assemble their own drones.

The functions of the drone include carrying ammunition to attack, reconnaissance of the enemy, carrying items, etc.

There are even some advanced drone chips that can add other skills or characteristics to drones, such as providing players with healing skills, or having self-destruct skills.

The assembly of drones is also divided into several parts, including drone chips, drone cabins, and energy cores.

Among them, the UAV chip is the key to determine the performance of the UAV. For example, the blood volume, attack power, armor, and skill capabilities of the UAV all depend on the UAV chip.

So a high-quality chip is the most important thing for a drone.

The main function of the drone cabin and energy core is to provide energy and recovery for the drone.

The energy core is the current power of the drone. When the power in the energy core of the drone is exhausted, it needs to go back to the cabin of the drone to replenish energy.

The drone's cabin is equivalent to a power bank, and its energy storage capacity also largely affects the drone's endurance.

The more powerful the drone chip, the more energy it may consume, so the drone cabin and energy core also need to keep up with the quality of the chip to a certain extent.

Otherwise, even if it is equipped with a powerful chip, the function of the drone may be limited due to insufficient energy supply.

Now that the basic drone chip formula is available, Zhang Cheng knows where to get the drone's cabin and energy core.

- New map Polar Ice Field.

There is also a golden treasure chest in the polar ice field. Zhang Cheng is almost sure that no one will grab the box from him when he goes to the polar ice field now.

But there is also a problem with going to the polar ice sheets, that is, the polar ice sheets are snowed all year round and the temperature is cold.

Players can easily suffer frostbite if they are not prepared to go directly into the polar ice fields.

The police sweater on Zhang Cheng's body was average in warmth, and a lot of equipment durability was also consumed when fighting against cancerous zombies.

Now Zhang Cheng's police sweater was slightly insufficient to support Zhang Cheng's high-intensity fighting and survival.

For the past two days, Zhang Cheng still went to Yuanxing University to collect drops of red blood diamonds every day, not for anything else, just to save up some formula fragments and squander them in advanced formula synthesis at one time.

In addition to the daily activities and the recipe fragments purchased in the mall, Zhang Cheng can harvest hundreds of recipe fragments on average every day in the past two days.

Zhang Cheng has also returned from Yuanxing High School today. Zhang Cheng did not stay at Yuanxing High School for that long today, so he only exchanged [-] formula fragments.

So far, Zhang Cheng has accumulated a total of five hundred recipe fragments!
The tenth level of advanced formula synthesis is unlocked, and each synthesis consumes 50 formula residual pages.

Counting it, Zhang Cheng can combine it at least ten times, and even if he has to get stuck, he can do it twice.

Moreover, at midnight tomorrow night, the rewards for the corpse wave leaderboard will be settled.

Judging from the results of Zhang Cheng and Tiangong occupying the top of the double list, Zhang Cheng will get another 140 recipe fragments by then.

Since the level of the zombie tide gradually increases, the rewards in the zombie tide rankings after each cycle will also increase accordingly.

By tomorrow, Zhang Cheng got more formula fragments and could continue to draw formulas.

Zhang Cheng clicked on the electronic screen of the formula research station, and found the new advanced synthesis section.

[Would you like to consume the remaining pages of the recipe*50 for an advanced recipe synthesis? 】

"synthesis."

The leftover pages of the formula were continuously arranged and combined on the electronic screen, finally forming a formula that looked like a drawing.

[Unlock the furniture formula - animal skin carpet]

"continue."

Zhang Cheng strictly stuck to the time interval for the next formula synthesis.

[Unlock formula...]

【Unlock...】

The fourth formula extraction.

[Unlock formula - advanced drone chip: Falcon]

Zhang Cheng instantly looked ecstatic, it was worth it!Even though the formulas that were drawn three times before were all furniture structure formulas, with this Saker chip, the two hundred pages of the formula are not worth the money!

Saker is a combat drone chip, which is very suitable for Zhang Cheng's current style of play.
