"good."
Su Yi agreed.
On the way back, Su Yi asked Niu Feibai, "Senior, I heard from Senior Sister Yuan that you are a master of formations. I have something to ask you."
"It's just a name."
Niu Feibai laughed and said modestly: "The art of formation is very profound. I have only studied it a little bit. I am not a master of formation. Just ask whatever you want to ask."
Su Yi said: "Can the Rainbow Eight Stones Formation be built a little bigger?"
The defense of the Rainbow Eight Stone Formation is very strong, but the one built by Niu Feibai only covers an attic.
With this range, it would be completely ineffective to quote it to the rear base.
And if the range can be expanded, for example, covering the entire cobblestone, it will come in handy.
"As long as there is enough material, it can be expanded."
Niu Feibai nodded, and then asked: "How much do you want to expand?"
Su Yi made a comparison in his mind and said, "It's about the same size as the previous island."
The overall size of the pebbles is indeed similar to the previous island.
If used for comparison, it is quite appropriate.
Niu Feibai: “….”
The Rainbow Eight Stone Array he built around the attic had consumed a lot of materials and spirit crystals.
If one were to build a rainbow eight stone formation that covered an entire island, it would inevitably consume a huge amount of materials and spirit crystals.
Even ordinary sects can’t withstand it.
Niu Feibai smiled bitterly and said, "Su Yi, it is too unrealistic to build such a large formation. Too many materials are required."
"What materials are needed?" Su Yi did not give up.
He already knew it would be difficult, but it could improve the safety of the rear base, which was too important. He had to overcome the difficulties and give it a try.
"There aren't many types of materials needed, only two, Eight-Level Stone and Rainbow Crystal. In addition, if you want to activate the formation, you'll need to consume a large amount of spirit crystals, and they have to be high-quality spirit crystals," said Niu Feibai.
"Are there any Balei Stones and Rainbow Crystals for sale on the market? What are the prices?" Su Yi asked.
Niu Feibai said slowly: "Eight-layer Stone and Rainbow Crystal are not particularly valuable spiritual materials. They are sold in almost every city, and their value ranges from three to five high-quality spiritual crystals."
“It’s not that expensive.”
Su Yi nodded and continued, "So how many Eight-layer Stones and Rainbow Crystals are needed to build such a large formation as I mentioned?"
Niu Feibai said in a deep voice: "To be conservative, each item will cost at least one thousand yuan."
"one thousand?"
Su Yi smacked his lips.
One thousand pieces of Eight-Level Stone and one thousand pieces of Rainbow Crystal, if converted into high-quality spirit crystals, it would be six thousand pieces.
And this is the minimum standard.
In addition, it takes spirit crystals to activate the formation.
Not to mention that he doesn't have so many spirit crystals. Even if he did, he would have to use them to transform the time spirit liquid first.
In this way, it became impossible to build a large-scale Rainbow Eight Stone Array in the rear base.
However, Su Yi quickly thought of a solution.
If a large one cannot be built, you can build several small ones.
For example, some small fortresses were built around the pebbles and protected by the Rainbow Eight Stone Array.
In this way, you can increase the defense of the rear base and also kill the enemy while hiding in the fortress.
Thinking of this, Su Yi said to Niu Feibai: "Senior, if I want to build the Rainbow Eight Stone Formation in the future, I will still need your help."
"No problem." Niu Feibai agreed readily.
