In his spiritual core, the spiritual energy vortex was spinning non-stop. Under the circulation of the Burning Spirit Scripture, it was as if it was being roasted by a raging fire. However, it also felt like it was being hit by a hammer. It was slowly being compressed and condensed.

The process seemed simple. However, it had extremely high requirements for the Foundation Establishment Realm cultivator. If the spiritual energy vortex was not solid enough and the control of the spiritual energy was not perfect enough, it could destroy the spiritual energy vortex, and even cripple one's cultivation.

The current Jiang Ming no longer had any flaws, and he was confident in building his foundation.

"According to the description in the scripture, at this rate, I should be able to finish it within a day!"

Jiang Ming was not in a hurry.

Just as Jiang Ming's mind was immersed in the process of building his foundation, a ray of light suddenly flashed in his body. Drops of light containing fragments of the great cultivation quietly fell on Jiang Ming's spiritual energy vortex.

The spiritual energy vortex suddenly expanded, and the runes in it were faintly visible. The mysterious energy of the great cultivation was flowing as if it was resisting the refining of the Burning Spirit Scripture, which slowed down Jiang Ming's progress by several times.

Jiang Ming was dumbfounded.

He naturally recognized that this was the rain of light that was born from the heavenly tribulation, and it poured into his body.

Jiang Ming knew that these fragments of the great cultivation were very precious. However, he did not expect that they would pop out at this time.

The Burning Spirit Scripture was running at full speed. However, the speed of the spiritual energy vortex condensation was exponentially slower.

After a few hours, Jiang Ming finally condensed the spiritual energy vortex to the size before the rain of light appeared.

The second rain of light appeared just in time and floated into the spiritual energy vortex.

Alas, his hard work was in vain again.

Jiang Ming gritted his teeth and tried his best to run the Burning Spirit Scripture, continuing to refine the fragments of the great cultivation.

After more than two weeks, Jiang Ming let out a sigh of relief. He was a little confused. He had never heard of anyone who took half a month to build their foundation.

Now, his spiritual energy vortex was like a nebula, spinning slowly.

Jiang Ming continued to temper and polish the spiritual energy vortex. Finally, there were no more fragments of the great cultivation that continued to fall. However, the spiritual energy vortex was also much tougher than before, which greatly slowed down the speed of his tempering.

Jiang Ming suddenly had an idea.

The old man on the starlit path did leave something else for him.

He flicked his finger, and a pile of seemingly ordinary firewood appeared.

At that time, the old man who was walking on the starlit path gave Jiang Ming the technique of the Hundred Tribulations Sacred Body, and the old man in the farmhouse threw a bundle of firewood to Jiang Ming.

"I don't know where this wood was cut from. However, it must be extraordinary to be given to me by a powerhouse like that. Will it be useful for my foundation?"

Jiang Ming's mind moved, and he separated a trace of spiritual energy to try to refine this bundle of firewood.

However, what Jiang Ming did not expect was that when his spiritual energy touched the firewood, the whole bundle of firewood suddenly disappeared in front of his eyes and appeared in his spiritual core.

The firewood that was suspended under the spiritual energy vortex suddenly burst into flames. The raging flames suddenly burst out, and they contained wisps of chaotic fog, which quickly integrated into the spiritual energy vortex.

In the spiritual energy vortex, there was a trace of mysterious fog, which was filled with a primitive and ancient aura. It was vast and boundless.

Jiang Ming was dumbfounded. Was this the real use of the firewood?

Or could it be that he had accidentally activated it in advance, and this firewood had a greater use?

"It doesn't matter; it's already been burned!"

Jiang Ming sighed helplessly. His sudden idea had slowed down the speed at which he was tempering the spiritual energy vortex.

"Good things take time." Jiang Ming could only comfort himself and continue to practice slowly.

Time passed by slowly. Two months had passed since Jiang Ming started building his foundation.

Jiang Ming was speechless. He had encountered several black winds in the past two months. Fortunately, this spiritual energy vortex seemed to have become stable after the baptism of the fragments of the great cultivation and the refining of the mysterious firewood. Although the speed of condensation was very slow, it had never collapsed.

"Finally, the moment has arrived!"

In Jiang Ming's body, the original spiritual energy vortex had almost turned into a wheel of light. It was undergoing the final transformation.

This wheel of light was the spiritual base. Entering the Golden Core Realm or even the Nascent Soul Realm depended on this.

Currently, Jiang Ming's spiritual base was filled with a faint red light, which was determined by the characteristics of the Burning Spirit Scripture.

After a normal cultivator reached the Foundation Establishment Realm, the fewer the flaws on the surface of the spiritual base, the higher the quality of the foundation would be.
