Huang Wuji, Sword Master, Yiye Guzhou and the others were walking with Zhang Yi on the streets of Purgatory City.
At this time, Huang Wuji was a little confused: "Can these defense towers really resist the ghost army?"
"After all, the defensive function of this temporary defense tower is definitely not as high as that of the secondary main city. Why don't we just start defense in Purgatory City and choose to build a defense tower?"
"That's a good question!"
Zhang Yi said: "Because Purgatory City is too big, the preparations we will make in the next step cannot cover the entire Purgatory City."
"But the defense tower is small and can enter a comprehensive defense posture."
"What's the next step to prepare?" Sword Master asked, "What else should I prepare?"
"These defense towers alone cannot stop the invading army of ghosts."
Zhang Yi said: "If we inject some more elemental crystals, it will be different."
"This is the last step of preparation we need to make before facing the ghost clan."
With Zhang Yi's introduction, everyone learned.
It turns out that in the world of Apocalypse, there is a mysterious prop that can be used to restrain the ghosts: elemental crystals!
However, elemental crystals can only be used with buildings and cannot be used directly to deal with ghosts.
Just like splashing salt water on the city wall, it can prevent ghost wizards from directly penetrating the city wall.
If you obtain elemental crystal reinforcement, the building's defense against ghosts will be even stronger!
Even different types of elemental crystals can bring offensive effects to buildings!
Hearing what Zhang Yi said, everyone suddenly became interested: "Where can I get this elemental crystal?"
"The elemental crystal is guarded by the goblins."
Zhang Yi said: "This is a product of the Goblin Kingdom."
Lin Xi was confused: "Goblin? What is that?"
"I know! Goblins living underground!" The sword master raised his hands and shouted.
As a result, everyone rolled their eyes.
Unexpectedly, Zhang Yi followed up and said: "Yes, goblins are goblins underground."
Everyone was shocked: "Why are you so careless..."
"Since goblins live underground all year round, it is generally difficult for ordinary people to see them."
In fact, goblins can also be understood as a race in the Apocalypse World!
However, this race is too weak and cannot be compared with humans, demons, aliens, dragons, and ghosts.
They have lived underground for generations, producing elemental crystals, and then selling the elemental crystals to other races to earn some food.
Underneath every player's main city, there is a goblin territory.
But to find them, you don't have to dig deep into the ground.
Because they live thousands of meters underground, ordinary digging cannot dig that deep.
They all have special underground passages leading to the Goblin Kingdom!
Naturally, the reason why Zhang Yi knows this is from the memory of his previous life.
In the previous life and later generations, when building the main city, some players discovered that the main city was built by combining elemental crystals. When the ghosts invaded during the Ghost Festival, the main city actually had a surprisingly super defensive effect against the ghosts!
But elemental crystals are very scarce.
In order to snatch the elemental crystals, players from major families even broke out into battles many times!
At this time, Yiye Guzhou said to Zhang Yi: "Senior, do you know where the passage to the Goblin Kingdom is? I will take people to the Goblin Kingdom to buy elemental crystals right away!"
Zhang Yi shook his head: "I don't know either."
"However, we don't have to search for it deliberately. When the time comes, the goblins will deliver the elemental crystals to each main city."
"Is there such a good thing?" Everyone was surprised.
Only through Zhang Yi's description did I understand.
It turns out: besides being weak, goblins have a special ability, which is to predict disasters!
This year is the first year of the ghost invasion, and all the major races have no idea that the ghosts are about to attack.
But the goblin foresaw the coming danger!
Just like: If God closes a door for you, he will definitely open a window for you.
And they foresee that elemental crystals can be used to fight the coming enemies!
Therefore, the goblins would bring elemental crystals to the main cities of the three major races every year three days before the Ghost Festival. While they wanted to help the three major races fight against the ghosts, they also happened to exchange the elemental crystals for some food back.
This is also the reason why Zhang Yi did not go to the Goblin Kingdom in advance and reserve elemental crystals in advance.
It's a pity: those goblins can't talk.
At least within the first three years, the three major races will not realize that the elemental crystals produced by the little goblins can be used to effectively fight against the powerful ghosts!
Therefore, according to historical progress, in the past few years, every year, ugly-looking goblins carrying a backpack appeared in major cities, and players and NPCs would directly drive them away.
Zhang Yi looked at the time and said: "The goblin should appear in the city the day after tomorrow or the day after tomorrow. All of you should pay attention then."
Huang Wuji, Sword Master, Yiye Guzhou and others all agreed: "Understood!"
At the same time, Zhang Yi also forwarded the news about the goblins and elemental crystals to the Dragon Clan Immortal and others in Flowing Light City.
Although there will no longer be a crisis of ghost invasion in Flowing Light City.
But the goblins will also appear on time.
When a city is built in the first-level main city in the future, a large amount of elemental crystals will be needed to give the city the absolute power to defend against the ghosts.
So it is necessary to collect elemental crystals in advance!
So, nothing happened in the next two days until the goblin appeared.
Zhang Yi is just killing monsters, practicing leveling, and teasing Xiaoba.
The intimacy level of the minibus seems to be stuck at 99%, and it can’t go up!
This is really a headache.
In addition, Zhang Yi stays with sisters Lin Ruo and Lin Yi every day.
Seeing their relationship getting better and better after the sisters reunited, I couldn't help but feel a little hesitation in my heart.
During this period, Zhang Yi deliberately contacted Lin Ruo several times through various opportunities and used the heart of memory to copy Lin Ruo's memory.
I found that her memories were pure and had no evil intentions!
Is it because Zhang Yi tampered with some of the history of this life that Lin Ruo will not become bad again in this life?
Zhang Yi still can’t believe this, the woman who deceived him for seven years in his previous life!
It’s better to always be on guard.
But even if he wanted to take revenge on Lin Ruo, Zhang Yi had to wait until she helped Fatty survive the mortal crisis in his previous life!
In suffering and waiting, I spent two days like this.
The time has come to the twelfth day of the seventh lunar month.
That night, Zhang Yi was brushing monsters and leveling alone in a level 190 high-end wild area outside the city.
Suddenly, I received a private message from the Sword Master: "Boss, the goblin you mentioned seems to have appeared!"
