Hikaru frowned and asked Rika: "Does the Ivern understand what I'm saying?"
[It doesn't, right now, the Ivern's thoughts are limited to that of an 8-year-old child. If you want it to know more, you would need to teach it. However, the Ivern can learn very fast, you probably won't need much time.]
Hikaru nodded, he tried to guide the Ivern back to the wall. True to what Rika said, the Ivern's ability to learn was very fast, it only took about 2 minutes for the Ivern to understand the structure of a wall.
The Ivern even simulated different types of walls, some of them could accommodate people inside and resist many types of magic.
The Ivern now said to him: "I need time for all the vines to take root in the entire territory, then I can create a wall. Master, the wall created by me is guaranteed to be very strong, even if it endures a barrage of magic attacks, it will be fine. As long as you provide me with enough water, I can recover indefinitely."
