In the following days, in order to raise funds for upgrading, Loulan also spent most of her time on the farm, in addition to reclaiming wasteland every day, she went to the dream canteen to find professionals who could manage the cattle farm.

His own fourth-level artisan hut has been built.

After so much time, Loulan almost forgot about this file, and when she asked Jack, she found out that the water cat engineering team had prescribed a super long list of raw materials to Jack, and Jack was running around looking for materials, which not only cost a lot of fantasy treasures, but also caused the completion period to be delayed again and again, and it was not completely completed until now.

Coming to the craftsman hut, Loulan found that the fourth-level craftsman hut has changed very much in appearance, I don't know if it's because the building is too advanced, the current craftsman hut has become futuristic, the overall appearance is like a cosmic flying saucer, and there are many strange patterns carved on the silver-white exterior wall.

After entering the artisan hut, Loulan soon found that the items sold inside had undergone amazing changes:

1. Double the strength of the glove, the number of uses is 10/10, the existing strength is doubled after wearing, and it is worth 100 fantasy treasures.

2. Wild Grass Terminator Potion Enhancement, a one-time consumable, after being poured into the Wild Grass, can make five pieces of wild grass the size of cultivated land completely disappear, worth 1000 Dream Tongbao.

3. Harvest Ganlin strengthened, one-time consumables, after use, can increase the daily output of all cultivated land by five times, worth 10,000 dream treasures.

4. Primary Inheritance Replica Scroll*1, a replica of a primary inheritance ability, which can be used by creatures other than the farmer, for 5000 Dream Treasure.

5. Rehabilitation straw mat, just sleep on it for one night, you can cure any disease and bad state, can be used by creatures other than the farmer, the price is 5000 fantasy Tongbao.

Loulan just glanced at it, and was attracted by the inheritance replica scroll and the healing straw mat, these two things, although extremely expensive, are extraordinary, and they are really of great benefit to Loulan in the future battle with zombies.

In particular, the appearance of the inheritance replica scroll gave Guan Jingyun and Xie Meina an opportunity to become stronger, and Loulan plans to develop more combatants in the future, and this inheritance replica scroll almost perfectly solves the problem of manpower.

In addition, Loulan is also very longing for the changes in her Jingyun after using the elf inheritance scroll: Jingyun, who is already as beautiful as a fairy, if she has the almost transcendent temperament of an elf and the long legs with amazing elasticity, as well as the skin that is so white and flawless that it is almost like clotted fat, and a pair of pointed white little ears... I'm going, it's really exciting to think about!

It's a pity that Loulan has no money in her pocket!

As a local tyrant with a daily income of more than 3 million soft sister coins, Loulan is also extremely dissatisfied with her current situation: she is desperately trying to make money every day, but then she feels more and more short of money, what kind of thing is this?

With the passage of time, the backlog of zombie brain crystals in Loulan's hands soon reached as many as three thousand, at this time, the efficiency of the boys' collection of brain crystals also slowly decreased, in addition to Loulan canceling the reward of the Douqi necklace in order to save money, the main reason is the problem of arms---- the arms left by the army have consumed too much, considering the safety of the entire campus after the recovery, some necessary weapons and equipment must be left just in case.

However, in order to help Loulan achieve the hidden task of eliminating zombies, the students did not sit idle, they couldn't shoot and drove around in the pea shooter armored car, using the pea shooter to kill the zombies, so after a few days, they actually invented a new tactic.

This new tactic is called the hunting method, which is usually done by dozens of pea shooter armored vehicles, they first gather together, and then set off at the same time, expanding to the periphery in a circle, gradually forming a large encirclement, and it is double-layered, that is, the double ring of two circles of armored vehicles, at this time there are basically no zombies in the encirclement.

After the encirclement is fully formed, several armored vehicles will continue to drive, so that there will be several gaps in the encirclement, once the gap is formed, the zombies will gradually pour in, and soon, the encirclement will be crowded with zombies.

At this time, the left chariots will drive back again, blocking all the entrances of the encirclement, so that all the zombies will be surrounded.

Once the siege network is fully formed, the killing of human zombies will immediately begin, while animal zombies will not be left at all, which can save ammunition to the greatest extent.

After all the human zombies are killed, the armored car in the inner circle will slowly drive inward at the same time, squeezing the space of the zombies while destroying the zombies, while the armored car in the outer circle will remain still, so that a relatively safe vacuum will be formed.

This method, although it is more cumbersome and relatively slow, is superior to high security and saving ammunition, and it was soon fully recognized, and at the same time, the zombie brain crystal in Loulan's hand also began to increase again.

As one great man said, it's worth the wait!

After nearly a month of unbearable waiting, Loulan finally succeeded in upgrading the Level 2 Biology Laboratory, not only increasing the maximum number of Pea Shooters to 5,000 at once, but also obtaining an advanced version of the Pea Shooter:

Burst pea shooter, the nemesis of zombies, within a radius of thirty meters (including the air) after being placed, any zombie creatures that come close will be attacked, after being attacked by pea shooters, zombie creatures will be quickly transformed into plants, and the plant has the effect of expelling zombies and purifying the environment.

The attack range has been increased by a full tenfold, which is simply powerful!

Loulan didn't expect that there would be such benefits in upgrading the second-level biology laboratory, and she was also very surprised, when she directly exchanged twenty consecutive pea shooters with the remaining more than a hundred fantasy Tongbao, and brought them back to the school in a hurry.

Loulan didn't bring these repeating pea shooters directly to Xu Wenzhi, but first took them to the wall at the entrance of the school and conducted a field test.

After placing a burst pea shooter on the wall, Loulan found that this guy was very different from ordinary pea shooters in appearance, not only was it much thicker, but it also had two new pea muzzles.
