Zhang Xuan's eyes lit up upon seeing the blood essence.
He quickly wrapped it within a layer of his zhenqi before he turned to Zhang Jiuxiao and said, "I'll take some time to examine it. For the time being, you should cultivate using the method that I imparted to you earlier."
After which, he turned around and returned to his room.
With a grasp of his hand, he created an isolation barrier around him and leaped into the Myriad Anthive Nest.
It would be best for him to be in an environment with absolute silence while studying Zhang Jiuxiao's blood essence. It would also be much safer as well.
After finding a place to sit down, Zhang Xuan had the droplet of blood essence float in front of him. With a tap of his finger, a droplet of blood essence was squeezed out of his fingertip, and he pushed it toward Zhang Jiuxiao's blood essence.
After careful examination, Zhang Xuan could only shake his head helplessly.
