Hao Ren and Vivian had discussed the venue of the summoning ceremony. Both of them had concluded that it must be failsafe. They had to anticipate all risk factors during the preparation phase. Vivian needed to a stable spell casting environment, a comprehensive security measure that could monitor the magic power, and a sophisticated amplification device, all of which were facilities of the magic realm. Hao Ren was familiar with modern technology but a noob when it came to things about magic. But Hao Ren did not need to study its specific principles; all he needed to do was to sort out the data and criteria listed out by Vivian. The Aerym Elves had prepared such a venue: the Magic Tower in the royal district.
