Dong Xuefeng hesitated for a moment and said, "That's good, but I don't recommend doing this."
"oh?"
Su Yi raised his eyebrows, "Tell me what you think?"
Dong Xuefeng said seriously: "To build a rainbow light eight stone formation that covers the entire rear base, too many materials are needed, which is not worth the effort. In addition, to activate such a large rainbow light eight stone formation, at least 10,000 high-quality spirit crystals are needed each time, which is unaffordable for anyone."
"Do you need so many spirit crystals?"
Su Yi smacked his lips hard.
Although he had just obtained a large amount of spirit crystals, it was only a few hundred thousand and could not withstand this level of consumption.
Moreover, the spirit crystal will be used to transform the time spirit liquid, which makes him even more reluctant to give it up.
Dong Xuefeng continued, "However, I have a compromise. We can build some small rainbow light eight stone formations and scatter them around the pebbles to protect them."
"This is a good idea. The task of arranging the formation and building defensive facilities in the future will be left to you." Su Yi said solemnly.
Dong Xuefeng's idea coincided with his.
In addition, he could also feel that Dong Xuefeng had unique insights in defense, so he simply gave the task to him.
"Don't worry, I guarantee you'll complete the task."
Dong Xuefeng seemed a little excited.
Su Yi was a little stunned.
I thought I just gave you a task, there's no need to be so happy, right?
In fact, he didn't know that Dong Xuefeng had almost no presence in the rear base because he was unfamiliar with everyone else.
I just wanted to use this incident to prove myself and gain everyone's recognition.
Su Yi did not dwell on this matter too much, and asked instead: "Old Dong, the defense of the rear base is of utmost importance. In addition to building a small formation, do you have any other ideas?"
Dong Xuefeng said quickly: "We can also dig some tunnels around the cobblestones to set traps, or we can use the tunnels to launch sneak attacks on the invading enemies."
"Tunnel warfare?"
Su Yi's eyes lit up.
At this moment, a scene from the movie "Tunnel Warfare" suddenly appeared in his mind.
It is impossible to defend against attacks on the enemy through tunnels.
In addition, he also thought of the explosion fruit.
The explosive fruit is somewhat similar to a landmine. It is buried in the ground. If the enemy accidentally steps on it, the consequences will be very serious.
Especially the power of hundreds of explosions should not be underestimated.
This has been verified in the dungeon of Yanyue City.
Tunnel warfare and mine warfare used together are definitely the enemy's nightmare!
In addition, arranging some vines on the ground can have an even more unexpected effect.
"That's a good idea you have."
Su Yi said affirmatively: "When we return, we will study it in detail."
"OK."
Dong Xuefeng was very happy to get Su Yi's recognition.
"Su Yi, we've arrived."
At this time, the [Intelligent Tank] suddenly reminded.
"Go down."
Su Yi calmed down.
When the [Intelligent Chariot] landed, Baisheng Ju Xiaohu came up with a group of strange beasts.
Those magical plants stood in a row, waiting for Su Yi's arrival.
Su Yi walked down and first glanced at the Demon Planting Tower, then asked Baisheng Ju Xiaohu: "Xiaohu, is everything okay?"
"Master, everything is fine."
Bai Sheng Ju Xiao Hu replied respectfully.
"That's good."
Su Yi nodded and ordered: "You all should return to the rear base first."
The Demon Planting Tower will be teleported away soon, so it would be meaningless for the strange beasts and demon plants to stay here.
