Zhen Hua was astonished to see this. Incorporating seven types of elements was basically the limit of heavenly refinement! During his forging career, he had completed seven-elemental heavenly refinement very few times, and he would always be severely wounded during the process.

He opened his mouth to stop Tang Wulin, but decided against saying anything in the end. Only by truly experiencing these things could the most effective lessons be taught.

On top of that, this was the heavenly platform, and he was present to protect Tang Wulin, so his safety was assured.

How exactly had he managed to draw upon so much power of heaven and earth? At this point, Zhen Hua was in no hurry to activate the heavenly platform.

A sufficient amount of elements had already been gathered, and the greater the amount of elements gathered, the greater the impact on the piece of metal during heavenly refinement, and the more fearsome the tribulation lightning would be.

Devouring Heaven and Earth!

With this powerful soul skill, there was no need for Tang Wulin to rely on the heavenly platform to draw upon the power of heaven and earth for him. He was the Son of Nature and the one who had been chosen by the plane, so his affinity with nature was far greater than anyone could imagine. The planar ruler couldn't directly assist him, but it could grant him the greatest level of affinity with the entire plane.

As his cultivation rank progressed, this effect became more and more pronounced.

At this moment, Tang Wulin had his eyes closed as he experienced all of the elemental fluctuations around him. There was gentle water, scorching fire, spritely wind, heavy earth, holy light, mysterious darkness, and unpredictable space.

All of these elements were parts of the laws of heaven and earth, and they were the building blocks of this entire world. These were the purest elements, and they brought the purest power.

During the past few years, Tang Wulin had experienced far too many things. In particular, he had encountered his godly father on several occasions, so his understanding of the laws of heaven and earth far surpassed that of the average person.

These experiences were all extremely precious, and they really shone through at a time like this.

The power of heaven and earth was gathered and absorbed, but as opposed to directly injecting it into the metal as Zhen Hua had done, Tang Wulin was guiding this power into himself.

Devouring Heaven and Earth could enhance his powers to a great extent, yet as the seven-colored rainbow light surged into his body, he didn't directly absorb it. Instead, he guided them toward his Heavy Silver Hammers, which quickly took on a rainbow hue.

He then raised them up into the air before sending them crashing down toward the newly soul refined piece of heavy silver.

"Boom!"

The entire heavenly platform tremored slightly from the impact, and the heavy silver instantly turned a rainbow color.

Instead of using Zhen Hua's method of forging, he was using a method that was relatively easier for himself to control.

Heavenly refinement was different for everyone, so he had to find his own path, and the path that he devised was to absorb and inject the power of heaven and earth into the metal through his Devouring Heaven and Earth.

This was something that he had already thought of while watching Zhen Hua's heavenly refinement, but he had to put it into practice to verify its feasibility.

The most important part of heavenly refinement was to grasp the laws of heaven and earth, then graft this interpretation of the laws of heaven and earth onto the metal to bestow upon it ability.

To put it in simpler terms, heavenly refinement involved injecting the power of heaven and earth into a piece of metal, then sealing that power using tribulation lightning.

It was naturally far easier said than done to complete this process, and an in-depth understanding of the laws of heaven and earth was imperative.

Tang Wulin had many unique and incomparable advantages in this regard. He was the Son of Nature and the one chosen by the plane. During his cultivation, the instances during which he had used his power as the Son of Nature, and that one occasion where he had used the Blood God Array, he had received many opportunities to experience the laws of heaven and earth. On top of that, he was at the Spirit Domain realm, so his understanding of the elements was also virtually unmatched.

Perhaps other Limit Douluos would also possess these abilities, but there were no Limit Douluos who were also master blacksmiths, and their affinity with the power of heaven and earth couldn't compare with that of the Son of Nature.

Tang Wulin was very familiar with forging as he had become a blacksmith at a very young age, and he had a very deep understanding of the internal structure, special characteristics, and even the emotions of all types of metals.

As such, the first feeling that he was struck by was that heavenly refinement didn't seem to be as difficult as his uncle-teacher had made it sound. At the very least, the injection of elements had been very smoothly completed.

He had drawn upon the power of heaven and earth using his Devouring Heaven and Earth, then used his own body to transmit this power into his hammers.

Tang Wulin could clearly sense that the piece of soul refined heavy silver possessed a certain type of suction force, allowing it to naturally fuse with the elements that he was directing into it. Under his conscious control, the elements began to leave a series of marks within the metal, each of which was extremely minute, resembling a series of tiny circuits. As a result, the internal structure of the metal began to transform as part of an evolutionary process.

So this was what heavenly refinement felt like!

As expected, only by truly experiencing it could he understand just how unique this experience was.

Even as Tang Wulin was marveling at this process, he didn't dare to let any complacency set in and continued with his injection of elements. Soon, he could sense that the tiny elemental marks within the internal structure of the piece of heavy silver was reaching full saturation, and he began to decrease the rate at which the elements were being injected. At the same time, it occurred to him that different types of metals were most likely able to withstand different amounts of elements. Heavy silver was one of more of the ordinary types of uncommon metals, so its capacity didn't seem to be very large.

However, he had gathered a considerable amount of elements, and after a brief moment of contemplation, he decided to keep all of them in his Heavy Silver Hammers.

From Zhen Hua's perspective, the piece of soul refined heavy silver had already turned a rainbow color, but immediately thereafter, his Heavy Silver Hammers also adopted the same hue, indicating that they were actively absorbing elemental power.

Zhen Hua opened his mouth to say something, but decided against it in the end. Distracting a blacksmith during heavenly refinement could result in dire consequences. As such, even though he was very displeased with Tang Wulin's overambitious actions, he caught himself before he could say anything. If he wanted to scold Tang Wulin, then he would have to wait until after the failure of his heavenly refinement.

The hammers were also made from soul refined heavy silver, but different pieces of metals that were soul refined at different times were bound to have massive fundamental differences, even if they were the same type of metal and refined by the same blacksmith. As such, it was downright absurd that he was attempting heavenly refinement on both his hammers and the piece of heavy silver that he was forging. This was even more difficult than the alloy heavenly refinement he had attempted earlier, so how could he not be angry?

However, Zhen Hua's anger was also intermingled with astonishment as the power of heaven and earth that Tang Wulin had gathered had outstripped even what he had managed to gather with the assistance of the heavenly platform. The seven types of elements were constantly flowing into his body, and he was handling them seemingly without any difficulty.

This was the power of the Son of Nature. If a normal person were to guide so many different types of elements into their own body at such large quantities, they could easily go into deviation or even self-detonate from triggering an elemental storm.
