It is recorded in the alchemy book that there must be three heavenly thunder and tempering pills for the foundation-building pill!

At this moment, she saw the dark clouds condensed in the sky, and she couldn't stop smiling. However, when she was happy, she saw that the dark clouds that had just condensed in the sky had dissipated again.

She was stunned and looked at the alchemy furnace instinctively. She happened to see the flames of the alchemy furnace extinguished, the spiritual power of the furnace body dissipated, and the alchemy furnace did not explode, but the medicine inside was wasted.

"How could it be? It was obvious that it was fine just now, who was wrong?" Her brows frowned slightly, with deep thought in her eyes. Seeing that a good furnace of elixir was turned off and wasted halfway, she stepped forward and checked the furnace.

After confirming that there was no problem with the alchemy furnace, she opened the cover of the furnace again, and a smell of medicine came out. She quickly turned her head and took out the medicinal materials in the furnace and took out the medicine.

When the medicinal herbs were rubbed in his hands, it scattered like ash in the grass and wood. His hands were covered with the gray-black gray, and the smell did not dissipate for a while.

"The final step is to condense the pill. There is no problem with the previous one, that is, there is a problem with the pill here. The spiritual medicine cannot condense into pills here, so the problem is too big." She murmured, thinking in her mind that the foundation-building pill recipe I saw in the library.

Instead of trying again immediately, she sat cross-legged by the alchemy furnace. While calmly adjusting her breathing, she also recalled the scene of her alchemy steps in her mind over and over again, and re-crushed it over and over again...

A few days later, Tang Ning was guarding the elixir in front of the furnace and doing the final step of condensing the elixir. At this time, a dark cloud once again condensed in the sky. This time, the dark clouds did not dissipate, but became thicker and thicker. The muffled thunder rumbling out of the clouds until the first thunder cracked down on the elixir furnace below.

"Boom!"

The first thunder fell, and Tang Ning also stepped aside. Seeing the thunder, the alchemy furnace vibrated. Lightning wrapped the entire alchemy furnace when the thunder shot down that day, and a powerful aura also filled it.

"Boom!"

The second thunder shot down again, tempering the elixir in the furnace. Then, the third thunder also rattled down. When the three thunder shot down, the dark clouds in the sky dissipated, and the lightning on the elixir disappeared with a wisp of fragrance spread out from the tiny breathable holes on the top of the furnace.

"Success!"

She was delighted, and a big smile appeared on her face. She quickly stepped forward and opened the elixir, and used her spiritual power to control the elixir inside into the jade plate.

"The elixir becomes white jade, the best quality!"

She looked at the three rolling white elixirs in the jade plate in surprise. According to ancient records, the best elixirs in the foundation building pill can turn into the color of white jade. They are treasures without any impurities. Only with the heavenly fire can such elixirs be refined. The foundation building pills refined by other refiners are all common brown-red.

Every medicine is three parts poisonous, even the foundation-building pill is no exception. However, if this top-quality white jade pill is free of impurities, only pure spiritual essence condensed.

If you want to refine such a top-grade white jade pill, in addition to the instinctive possession of the Heavenly Fire, you must also master extremely high alchemy techniques and the accuracy of the medicinal properties, as well as pure spiritual energy and breathing, in order to refine this top-grade white jade pill.

However, there are top-grade elixirs in this world, but this legendary white jade foundation-building pill has never appeared.
