After hanging up the phone, Zhang Fan began thinking about Zhao Lin's antidote. He could perform divination, and so far, all his divinations had been 100% accurate. He could use this to formulate the antidote for the Seven Flower Powder.

Zhang Fan leaned back in his office chair, his eyes closed, seemingly resting, but in reality, his left hand was secretly making calculations.

He first divined the weight of one of the ingredients in the antidote, based on his own guess, to determine the accuracy of the divination.

The antidote for the Seven Flower Powder was too complicated. An hour later, Zhang Fan finally figured out the proportions of the four ingredients.

His spiritual power had been completely exhausted, so Zhang Fan took advantage of this momentum and immediately absorbed the spiritual power of the ebony bracelet.

The golden sheen of the ebony bracelet is no longer as strong as before, and its luster has become dull.

Due to the large amount of energy consumed, Zhang Fan's spiritual energy absorption rate was extremely fast at this moment.

The spiritual energy quickly gathered in the dantian, forming a spiritual energy core the size of a football.

Zhang Fan immediately sat cross-legged, fully relaxed his body, and coordinated his breathing with his mind, expanding his abdomen outward when exhaling and compressing his dantian when inhaling.

Then, he used his mind to guide his spiritual energy to impact his upper dantian. Once he broke through the upper dantian, he could enter the first level of Qi Refining.

Zhang Fan held his breath, squeezed his abdomen hard, and at the same time guided his spiritual energy to rush to his upper dantian.

The walls of the upper dantian are thicker than those of the middle and lower dantian. If the walls of the lower dantian are likened to the walls of an earthen house, the walls of the middle dantian are like the thickness of a brick house, and the walls of the upper dantian are like a thick city wall.

This demonstrates the extent of the difficulty involved.

This time, the barrier in the upper dantian only trembled slightly, proving to be extremely solid.

Zhang Fan was not discouraged. He was only 22 years old, and his current level of cultivation was already more powerful than many old cultivators who had been cultivating since childhood. He was still young and had plenty of time.

The spiritual energy he absorbed repeatedly impacted the barrier of his upper dantian.

Once, twice, three times...

Zhang Fan had completely absorbed the spiritual energy of the ebony bracelet, leaving it looking dull and lifeless.

Zhang Fan tried again to break through the barrier in his upper dantian. The hard and solid barrier was already on the verge of collapse under his repeated attacks.

Because of the frequent use of spiritual power, his cheeks were flushed, steam was rising from his head, and his whole body was covered in sweat, exuding male hormones.

With a loud bang.

The barrier in the upper dantian could not withstand the pressure and collapsed with a crash.

Zhang Fan felt an unprecedented sense of comfort; his limbs, his entire body, his meridians, and even every pore were cleansed by spiritual energy.

It felt like being on a cloud, and I felt like I was floating on air.

Zhang Fan couldn't help but let out a comfortable groan.

Just as Ji Zhi was about to knock on the door, he stood outside and his pupils suddenly widened in shock. He had come at the wrong time.

What were those two doing that made Zhang Fan groan?

He blushed and withdrew.

Zhang Fan was filled with excitement, his whole body was burning with heat, and all he wanted to do was jump into the ice water for a cold shower.
