Under the slightly surprised gazes of Tang San and the others from Shrek Academy, Bone Douluo returned to Ning Fengzhi's side and stood silently behind him like a loyal guard.
He did not speak, nor did his lips so much as move, but a thread of Soul Power carrying his voice slipped into Ning Fengzhi's ears.
Bone Douluo was transmitting his words to Ning Fengzhi through Soul Power, using a technique known as the Sound-Pressing Technique.
The Sound-Pressing Technique was a method of transmitting sound, or rather, a secret art. Usually, only experts at the Soul Douluo level or above could master and use it, because it involved not only manipulating Soul Power and sound, but also using Spiritual Power.
On the Douluo Continent, only Spirit Masters at the Soul Douluo level or above could make even rudimentary use of Spiritual Power.
Of course, certain exceptionally gifted Spirit Masters who already had one foot in the Soul Douluo realm could also manage it to some extent, such as Ning Fengzhi.
At that moment, Bone Douluo and Ning Fengzhi were communicating through the Sound-Pressing Technique. Only the two of them could hear their voices; everyone else present, including Tang San, was too low in cultivation to detect a trace of it.
In that silent exchange, Bone Douluo quickly recounted everything to Ning Fengzhi, down to the smallest detail, about Tang Hao's presence and the discussion they had just held.
After listening, a hint of surprise appeared in Ning Fengzhi's eyes, but his expression soon returned to normal. Without betraying anything, he looked up at Tang San across from him.
He had never expected Tang San to be the son of Clear Sky Douluo Tang Hao, much less that Tang Hao had been hiding in the shadows to protect him all along.
