Xu Xing continued to practice. On the 36th day, his cultivation reached the fifth level of foundation building.

On the 49th day, Xu Xing once again received a system warning, prompting him that the space barrier was damaged by 10%.

However, Xu Xing felt that his cultivation was about to break through to the sixth level of foundation building, so he did not stop, but continued to practice.

Finally, on the 52nd day, when Xu Xing's cultivation reached the sixth level of foundation building, the damage to the space barriers of his carry-on space had reached 13% in the system's warning message.

Xu Xing thought to himself, "As my cultivation level improves, the energy consumption of barriers in the casing becomes more and faster!"

While thinking, Xu Xing once again chose to consume the cold soul to repair the barriers of space.

When Xu Xing saw the experience value that needs to be consumed, he was suddenly surprised that he actually needed to consume 1,800 experience value!

It doubled the experience value required last time!

After thinking for a while, Xu Xing understood that he should have not stopped to repair the space barrier when it was damaged by 10%. The additional 3% was caused by continuing to practice later, so he needed to spend 900 more experience points to repair it.

This made Xu Xing feel a little painful and secretly reminded himself: "In the future, unless you have to, you must not damage the space barrier of your portable space by more than 10%! Otherwise, this would consume too much experience value!"

After the repair was completed again, the cold soul marrow that was originally the size of an egg was completely consumed.

This made Xu Xing feel a little sad. According to his estimate, if the remaining cold soul marrow was only 10% damaged in the repair space, it should have been repaired twice, but now it has been consumed in one go.

However, when I think of the large amount of cold soul marrow at the bottom of the pool outside, the feeling of distress is not that strong.

Next, Xu Xing left his carry-on space and began to try to collect the cold soul marrow at the bottom of the pond again.

After his cultivation level was improved, Xu Xing's resistance to the cold aura emitted by the cold soul marrow was greatly improved.

Faced with these cold and ghost marrows, Xu Xing no longer needs to use his full strength to move his skills, and he can move easily and freely.

Xu Xing released the flying sword again and began to split the cold soul marrow.

However, since his two skills, "Five Elements Sword Technique" and "Body Sword Technique", are still at the foundation-building level, the slitting process is still not very smooth.

Even if he converted the magic power of the flying sword into the five-color magic power generated by the "Five Elements Dharma", the effect would still be not very ideal.

After all, "The Five Elements Dharma" is not a sword practice technique, it prefers Dharma practice.

When using the "Five Elements Dharma" to control the flying sword, I always feel that there is an invisible film separated by a layer of invisible film, which is not so easy to use.

After working hard for half an hour, Xu Xing finally cut off a piece of fist-sized cold soul marrow.

When collecting this cold marrow, Xu Xing accidentally held it in his hand. After feeling the cold air coming from above, Xu Xing found that he had not been frozen into ice.

This made Xu Xing move slightly, and he thought to himself, "I was very reluctant to resist these cold air before, so I couldn't use the method of using the Five Elements Dharma to adopt the cold soul marrow. Now that I can easily resist, why do I still use the flying sword?"

Xu Xing never regarded himself as a pure sword cultivator, nor did he feel that he had to practice only the sword cultivator on his future path.

In his opinion, as long as he can increase his cultivation and strength, no matter what kind of sword cultivation he practices, he can do it.

In this way, Xu Xing took back the flying sword and changed his method.

The most powerful method of "Five Elements Dharma" is the five-colored divine light, so Xu Xing naturally used this magic without hesitation.

The five-colored divine light brushed towards a large area of ​​cold soul marrow in front of them, and the cold aura they emitted suddenly became stagnant.

This made Xu Xing feel a little happy, and he was also worried that these cold soul marrow would be damaged by this.

He stepped forward and looked carefully and found that this cold marrow was only isolated from the five-colored divine light. The cold air was retracted and contracted, and it was not damaged in essence. It only took a while to recover on its own, so he felt relieved.

Without the invasion of the cold air, Xu Xing easily divided the large area of ​​cold marrow in front of him along the connection where they grew, and put them into his storage bag one by one.

After seeing the power of their cold air, Xu Xing dared not easily put them into his portable space.

Otherwise, even if the elixirs planted in the portable space have the characteristics of resisting cold and freezing, they may not be able to withstand the cold air they emit.

After collecting for a long time, Xu Xing had completely filled a storage bag.

At this time, Xu Xing had made new discoveries. Not all the cold soul marrow qualities are the same at the bottom of this pond.

Just like this large area in front of him, they are distributed more densely and have stronger cold air.

Xu Xing casts five-colored divine lights three times in a row before suppressing their cold air.

Xu Xing walked forward with joy to collect it, but just after collecting several pieces, suddenly a ray of dark blue flame fell silently on him at an extremely fast speed.

Xu Xing felt his whole body suddenly become cold, and the surface of his body quickly condensed into ice at a speed visible to the naked eye.

This surprised Xu Xing and hurriedly used his magic power to call nearly 70% of the five-color magic power in his body before suppressing the chill.

After suppressing the coldness, a light blue flame appeared in Xu Xing's palm.

The flame was extremely weak and small, just a little thicker than the hair.

Before Xu Xing could take a closer look, dozens of wisps of dark blue flames emerged from the cold marrow around him again, all of which floated towards him.

But this time Xu Xing was prepared and five-colored divine lights circulated around his body. The flames that were floating over were all suppressed by the five-colored divine lights. Finally, they gathered and fell into the palm of his hand.

This time, all the gathered flames, after they were added, were about the same size as millet grains.

However, Xu Xing's attention was not on the flames as big as millet grains in the palm of his hand, but staring at the cold and ghost marrow in front of him.

With a loud bang, a large piece of blue flame rose from the cold marrow and swept towards Xu Xing.

Xu Xing stood there, protecting his body with five-colored light gods, allowing the flames to rush over.
