As Julius opened his eyes upon hearing the ten footsteps, he understood he had been cultivating from dawn to evening without realising it. The Qingming Sutra of Serenity was extraordinary and caused his cultivation speed to increase significantly.
Instead of shoving natural energy into his meridians and randomly guiding it to his dan tian, he made it travel through a specific route, conserving its energy and nourishing his body while he purified it using the sutra.
In addition, his natural affinity finally proved beneficial as it helped him feel and comprehend the five elements during his meditation. With the sutra, his affinity and his gladius' ability, he was sure he would reach the Golden Core Realm in a wink.
He didn't delve too much into the battle techniques yet, but after mastering them, he would finally have a way to use his Qi efficiently in battle instead of mimicking his big brother's use of mana.
