The essence of the herbs is lost from the broken area, giving off a refreshing fragrance.

Picking up this imperial medicinal herb called Dingninggen and resealing it with Xuan Qi, Wu Yu sent it into the Empty Source Stone again as if he didn't believe in evil.

With the sound of Xuan Qi exploding, Ding Ninggen was missing again.

However, this time Wu Yu saw clearly, after Dingningen fell towards the silver ray, that is, the power of space, the space around Dingningen was distorted, thus showing the illusion that Dingningen had shrunk and its appearance had become blurred.

This shows that the idea of using empty source stones for storage should be feasible, and there is no problem with the power of space itself, and the problem should be in the Xuan Qi.

So, Wu Hui picked up Dingningen, which was nearly one-fifth shorter, and ruthlessly started a new experiment.

The silver flashed, and Dingningen was once again missing by a tenth.

I didn't see it clearly, so try it again.

Brush...... Another tenth is gone.

If this scene is seen by a doctor or a Dan master, it will definitely hurt so much that you can't breathe.

Dingning root is an imperial medicinal material, if it is refined as the main material to make a Dingning Pill that can calm the qi and calm the gods, it can greatly improve the success rate of breaking through to the imperial realm, and it is definitely one of the top medicinal materials that can be listed on the current Xuanzhi Continent.

At first, Wu Yu also felt a little distressed, but when he saw the royal medicinal materials all over the medicine garden and the imperial medicinal materials that could be seen everywhere, the only trace of distress had already been thrown out of the clouds.

The speed at which the Xuan Qi exploded was so fast that Wu Yu barely saw what happened when the Xuan Qi exploded during the fifth test.

At the moment when the Xuan Qi exploded, the part where Dingningen came into contact with the power of space seemed to have been cut off by the sharpest knife in the world, the incision was flat and smooth, without a trace of burrs, and the part that was cut off disappeared out of thin air.

Wu Yu looked inside the Void Source Stone, but did not find the part of the medicinal herbs that had disappeared, thinking that it should have been wiped out in the process of contact with the power of space.

When fighting, if you can wrap part of the enemy's body with Xuan Qi, and use the power of space to cut and annihilate the property, it will have a surprising effect.

Slightly distracted, Wu Hui returned his mind to the problem he was facing.

After trying so many times, although he could clearly see what happened after the Xuan Qi exploded, he still didn't understand why the Xuan Qi suddenly exploded.

The Dingningen in his hand has been truncated by half, and theoretically no matter how much it is truncated, Dingningen should still belong to the imperial product, but the amount is reduced by half.

But in fact, after the medicinal herb is damaged, its essence will be lost quickly, although Wu Hui wrapped it in Xuan Qi at the first time, but with many tests, the quality of Dingningen has dropped to the king product, if you try two or three more times, maybe it will be reduced to the level of five grades.

The damaged medicinal herbs were difficult to preserve, so Wu Yu simply broke the jar and continued his previous attempt.

The silver rays from the Void Source Stone shone again, and just as Wu Yu was engrossed in trying to find the cause from the process of the Xuan Qi explosion, Ding Ninggen actually disappeared in front of him out of thin air.

Wu Yu was stunned for a moment: Succeeded?

Sensing into the Void Source Stone, under the spatial origin, Wu Yu found the half of the Dingning Root that had just disappeared.

In this way, the storage function of the Empty Source Stone was finally confirmed, and Wu Yu couldn't help but be a little excited, but questions followed.

It's the same Dingningen, why couldn't the Void Source Stone be placed before, but now it can be again?

Before and after the comparison, there were only two changes in Dingningen, the volume became smaller and the quality decreased.

Whatever the reason, you'll find out by trying.

Just as Wu Hao's perception was about to exit the Void Source Stone, he suddenly noticed that the essence of Dingningen was no longer lost, as if time had stood still around the space where it was located.

Is time standing still in the Void Source Stone?

Another question arises.

However, Wu Yu was not in a hurry to dig deeper, and the top priority was to find out which of the volume and grade was the limiting factor affecting the storage of the empty source stone.

He took a piece of imperial medicinal herb that was also root-shaped and almost the same size as the truncated Dingning Root, so he repeated the technique and threw it into the Empty Source Stone.

The Xuan Qi exploded, and this imperial medicinal material was wiped out by the power of space.

Wu Yu waited quietly, allowing the essence of this top-grade medicinal material that was enough to make the vast majority of Xuanzhi fight for blood flow in vain, until its quality dropped to the level of Wang Pin, he wrapped it in Xuan Qi and sent it into the Empty Source Stone again.

The silver light flashed, and the medicinal herb disappeared as expected.

Without rushing to make a conclusion, Wu Yu took another Wang Pin medicinal herb that was much larger than Ding Ninggen and tried it again, and finally confirmed that the Empty Source Stone could only store items that were no higher than Wang Pin.

It was not clear why Wu Yu was exact, but he guessed that the upper limit of the grade of the items that could be stored in the Empty Source Stone was likely to be related to his current level of Xuan Power, and perhaps when his Xuan Dao cultivation broke through again in the future, he could try to see if he could deposit the imperial items to verify his guess.

After confirming that the storage function of the Empty Source Stone had a limit on the grade of the item, Wu Hui began to think about the state of Ding Ninggen in the Empty Source Stone.

Why is the essence of Dingningen no longer lost, is it because the time is still in the empty source stone, or is it because the internal space has a spatially limiting effect on foreign objects?

If it was because of the former, it meant that Wu Yu could store a large amount of food in the Empty Source Stone without worrying about food rotting.

If it's because of the latter...... It doesn't affect his ability to stock up on food, at most he eats it before it rots. In fact, if you build a strong physique, even if you eat rotten food, it won't be a big deal, as long as the food can provide energy.

However, Wu Yu was still ready to find something to experiment, not only to satisfy his curiosity and desire to explore, but also to consider Mu Feng'er - when he left here in three days, three years had passed since the outside world, and he didn't know where Qin Lei had gone, Qin Lei had made him swear to protect Mu Feng'er, so before finding Qin Lei, he had to take Mu Feng'er with him all the time, and he had to plan in advance for a top priority like eating.

If time in the Void Source Stone really stood still, then he could replenish enough food from the Juggernaut.

The squeezed fruit is easy to rot, so Wu Yu is going to go to the orchard to pick a few fruits and try it, and now, he wants to test the capacity of the Empty Source Stone.

So, Wu Hao is like a hard-working little bee, collecting medicinal materials in the medicine garden, and he has a rich knowledge of medicine and Dandao, he did not specialize in high-grade medicinal materials, but was evenly stained with rain and dew, and each medicinal material was picked a little bit into the 'stone'.

The storage consumes not much Xuan Qi, and with the concentration of Xuan Qi in the small world and the reverse Xuan Gong comparable to that of the Heavenly Product, this consumption is quickly replenished.

As Wu Yu was collecting medicinal herbs to test the capacity of the Empty Source Stone, that familiar voice suddenly sounded in his ears again.

"What are you doing here?"
