To be the best leader, you must also be the strongest leader!

Sun Yi smiled and nodded, then a ball of true energy flew out, directly wrapped the set of spiritual armor inside and began to refine it. It was just a first-level ninth-grade spiritual weapon, and it didn't take Sun Yi any effort to refine it.

However, during the refining process, Sun Yi still discovered a problem, that is, the speed of refining spiritual armor is much slower than refining a flying sword of the same level, and it consumes more true energy.

He could easily refine a set of spiritual armor, but if it were to be refined by a cultivator in the Qi Refining Stage, the time required would probably be several times longer than refining a flying sword of the same level.

Soon Sun Yi succeeded in refining the spiritual armor.

With a thought, the spiritual armor turned into a stream of light and penetrated into Sun Yi's body.

Then there was a flash of light, and the spiritual armor emerged again, directly wrapping Sun Yi's body inside.

At this time, Sun Yi's whole body was completely wrapped in spiritual armor, except for his head and neck, the rest was covered without any blind spots.

He stood up, moved around casually, then flew up again and turned around, activating the five spirit swords to practice sword techniques.

A full stick of incense passed before Sun Yi put away the magic sword and returned to the crowd.

"Master, how does it feel to wear this set of spiritual armor?" Gu Qingcheng and the others all looked at Sun Yi eagerly, with an expression of great anticipation.

Sun Yi smiled and said, "Wearing this set of spiritual armor feels almost the same as wearing the sect's uniform. Movement is not affected at all. However, my hands are a little uncomfortable being wrapped in the spiritual armor. It's like wearing a pair of gloves. This can be slightly modified. It would be best if the hands can be hidden when not needed."

"Come on, let's try the defensive power of the spiritual armor again. Master Yan, you try the attack." Sun Yi looked at Master Yan.

"Okay, then I will start the attack. Master, please be careful." Old Yan didn't care that the spiritual armor was worn by Sun Yi. He wanted to know the details of this set of spiritual armor immediately.

Sun Yi stepped aside and began to increase his strength to urge the true energy in his body to be injected into the spiritual armor. Suddenly, the surface of the spiritual armor on his body bloomed with flowing light, as if a layer of membrane had appeared in an instant.

The next moment, Old Yan sent out several sword energies towards Sun Yi. The strength of these sword energies was not high, only at the fifth level of the Qi Refining Stage.

When these sword energies fell on Sun Yi, they were directly bounced off by the spiritual armor and had no effect on the spiritual armor at all.

Combined with Old Yan's continued efforts to increase the strength of the sword energy, the strength of the sword energy was soon increased to the level of the late stage of Qi Refining, but it still could not cause any damage to the spiritual armor.

Then, Old Yan increased the strength of the sword energy to the level of great perfection in the Qi Refining Stage. These sword energies shot at the spiritual armor and were blocked by the spiritual armor one after another.

Although the surface of the spiritual armor flickered for a while, there was still no problem in the end.

"Such strong defense, even the attack of the Great Perfection of Qi Refining Stage has little impact. This spiritual armor is only of the first level and ninth grade quality."

"Yeah, this defense is pretty good."

All the weapon refiners around were watching attentively, and they were all very satisfied with the defensive power of the spiritual armor on Sun Yi.

Sun Yi smiled and said, "Master Yan, please continue. I want to see the endurance limit of this set of spiritual armor."

"Okay, Master."

Old Yan pointed his right hand towards Sun Yi, and a flying sword turned into a sword light and slashed down directly. The power of this sword light was stronger than the previous sword energy.

Sun Yi still only used the spiritual armor for defense. The sword light fell on the spiritual armor, causing the light on the surface of the spiritual armor to continue to fluctuate, but it finally blocked the sword light.

Sun Yi was very satisfied when he saw that there was no damage on the surface of the spiritual armor. However, as Yan Lao's attack power increased, Sun Yi also noticed the problem with the spiritual armor.

First of all, the spiritual armor greatly increases the consumption of true energy. With such a high consumption of true energy, ordinary Qi Refining cultivators cannot hold on for long.

"Master, this time I'm going to use the power of the Foundation Establishment Stage." Old Yan reminded.

"Okay." Sun Yi nodded.

Old Yan pointed at Sun Yi again, and a golden spiritual sword turned into a golden sword light that fell from the sky and directly slashed Sun Yi.

The surface of the spiritual armor shimmered slightly, and although it finally blocked the sword light, the patterns inside the spiritual armor were also damaged.

"Keep trying." Sun Yi paid attention to the condition of the spiritual armor while asking Old Yan to continue his attack.

Old Yan nodded, and then continued to release golden sword light to attack Sun Yi. Then the spiritual armor was hit by the sword light again, and the damage to the internal patterns was even more serious.

After blocking the sword light for the third time, the spiritual armor's endurance finally reached its limit, the internal patterns were completely damaged, and the light flashed and retracted into Sun Yi's body.

Sun Yi stretched out his hand, and the spiritual armor in his dantian appeared in his hand. At this time, the spiritual armor was only the size of a palm and looked very delicate. However, the spiritual armor now looked dim and had lost the aura of a first-level ninth-grade spiritual armor. It was obviously damaged.

Everyone gathered around, staring at the spiritual armor in front of them.

"Overall, the defensive power of this set of spiritual armor is quite good. If a cultivator in the Qi Refining Stage has a set of this kind of spiritual armor, his ability to survive will definitely be greatly improved."

"Yes, it can withstand the attacks of three cultivators in the early stage of foundation building. The defensive power of this set of spiritual armor is indeed extraordinary." Old Tong nodded.

"However, this set of spiritual armor can only withstand the attacks of three cultivators in the early stage of foundation building because it is worn by the sect leader. If an ordinary cultivator in the Qi Refining stage wore this set of spiritual armor, they probably wouldn't have such ability." Gu Qingcheng's thoughts were different from theirs.

Sun Yi smiled and nodded.

"Gu Qingcheng is right. I can use this set of spiritual armor to withstand three attacks from an early Foundation Establishment cultivator because my true Qi far exceeds that of an ordinary Qi Refining cultivator."

"Honestly speaking, if this set of spiritual armor is only used by us disciples of Qingyun Sect, with the abundant true qi in our six dantians, we can really bring out the defensive power of the spiritual armor."

"But the spiritual armor's disadvantage is that it consumes too much Qi. We must find a way to reduce the consumption of Qi. Otherwise, this spiritual armor will not have a big market."

"But how can we reduce the consumption of true energy?" Old Tong frowned and fell into deep thought.

The others also fell into deep thought, but Sun Yi looked at Gu Qingcheng with a smile: "Gu Qingcheng, do you have any ideas?"

Gu Qingcheng's eyes flickered, and she suddenly suggested, "We can find a way to set up a formation on the spirit armor that uses spirit stones to activate it. When the time comes, the user will use their true Qi as a guide, relying mainly on the spiritual energy provided by the spirit stones to activate the spirit armor's defense. This way, the consumption of true Qi will definitely be greatly reduced."

Sun Yi nodded in satisfaction after hearing this: "Yes, this is a good solution. Next, we need to improve the quality of the spiritual armor and think about how to arrange the formation on the spiritual armor to achieve the goal of reducing the consumption of true energy."

"Okay, with the basic technology of refining spiritual armor that we currently have, there will be no problem in refining the second-level spiritual armor. Let's get started without further ado." Old Yan couldn't wait to research the second-generation spiritual armor.
