" The first step would be consuming this pellet made by the best apothecary. Here, take them. " The old man handed them a pellet the size about a third of the little finger. They swallowed it with a glass of water.
" Let's go, we need to travel far, " he urged them to climb his avean pet the size of an elephant. They flew off to a distant mountain that had a weird property. It had an unstable space-time that fluctuated between a small space and a large one.
" The first stage of fortification is to survive this spatial turbulence. Stay within it till you faint. Believe in me. Now, go " he pushed them both into the unstable space and waited outside whilst observing their condition using an observation spirit formation.
Dastan and Sarah felt as if their bodies were being crushed in one instant and being stretched till the endurance limit in the next. The cycle continued till they could no longer bear it and fainted. A mysterious energy healed them to perfection whilst protecting them from the turbulence. The cycle of healing followed by crushing and stretching continued till their bodies were no longer affected by the turbulence. The old man picked them up and left the peak.
The duo woke up in a pond smelling like plants half submerged into it. " Good that you woke up early, come out, bathe and have dinner. We'll go to phase 2 tomorrow. " "Yes, teacher. "x2
The duo refreshed themselves only to be stunned by their appearance. Their bodies were translucent and bright crimson in color as if made of rubies. Their see through bodies amazed them.
The next morning, the old man escorted them to a volcanic lava pool and told them to plunge into it. They stared at him flabbergasted. He assured them that it was a part of their fortification. Helpless, they could only jump into it.
The duo felt as if their bodies were being roasted alive over a slow flame. Just as they felt they were about to give in and burn it ashes, a mysterious energy covered their bodies from the heat and healed them to perfect health before disappearing.
This slow grilling followed by healing went on until they could swim in the lava as if it were a swimming pool. The old man picked up his fainted children and left the volcano.
The duo once again woke up in the nostalgic feeling of being half soaked in plant smelling pool. The words spoken by the old man were the same as well. But this time, their translucent bodies appeared to be made of bright red carbuncles.
The next morning, they were almost frozen to death in an ice glacier again repeating the cycle of thawing and healing by mysterious energy and freezing again till the cold couldn't affect them anymore. Once again, they gained consciousness in the pool and cleaned up for dinner only to see their translucent bodies appeared to be made of pure white jades.
The next morning, they were hung above a sea that looked abnormal. It battered them with powerful waves and currents that almost tore them apart. Again, the mysterious cycle of healing and bashing continued till the sea was ineffective on them. This time, their bodies were appeared to be made of aquamarines, crystalline blue in color.
The next morning, they were plunged into a sea of poisonous animals of all kinds and the vicious cycle of healing and poisoning repeated. This time when they observed their bodies, they were appeared to be made of emeralds, a shade of light green that shone in moonlight.
The next morning, they were subjected to an enormous oppressive might that put them in the verge of tears almost crushing them to the ground. The cycle of crushing and healing went by till they could be no longer affected by it. Their bodies glowed as if been made from topaz, a bright yellow gem stone.
With this, their body fortification was completed without causing them any long lasting injuries or killing them.
