Since the cave was here for a long time and was manually carved out, it was obvious that it would erode from the natural elements after time. Because of this, small pieces of rocks and soil would fall from the ceiling from time to time.

Some of these would fall on the barrier that surrounded the spirit Qi spring. But the barrier would not let them fall inside, because of which they would roll off it and fall around its edges.

While this was a very mundane thing, it gave an important bit of information to Lin Wu.

"Oho, so the barrier does not set off an alarm when it is touched. Though it should depend on the level of impact that is levied on it, seeing as the small rocks do not affect it. A light touch by someone should have the same effect I presume." Lin Wu hypothesized.

'Let's see if my estimation is correct…' Lin Wu thought before extending a very small part of his tail forward.

It was only as big as the rock that had previously fallen and hopefully should not cause any problem.

Lin Wu extended it very slowly and watched it approach the surface of the barrier. His breath was held in his throat as he finally touched it.

He had thought that something would happen, a flicker, ripple or anything; but nothing did. It was as if the barrier was unresponsive.

"Hmm… this is much better than I thought. Let's up it a little bit." Lin Wu muttered before increasing the force.

He doubled his previous force and still nothing had happened. He kept on increasing it little by little, seeing no response. By the time two hours had passed by, Lin Wu was now at twenty percent of his full strength.

~shua~

Finally, he saw a ripple appear on the barrier and spirit Qi fluctuations came from it. He immediately stopped there, and the barrier also stopped whatever it was doing before calming down.

"Huh… the strength needed is a lot more than I expected. And even then it stops if it is withdrawn. I guess the threshold is there in case more rocks fall on it or the roof collapses. Unless something of that level happens the sect would not get alerted." Lin Wu said to himself.

Having understood this, Lin Wu realized that there were a few more things he could try out. He especially had something that he had been wanting to try out.

Lin Wu extended his tail towards the barrier once again, but this time he amplified it with his spirit Qi. This time the undaunted sapphire body art was in full effect and a coating of spirit Qi could be seen around his tail.

As soon as he touched the surface of the barrier, Lin Wu could see that the spirit Qi had actually passed into it partially. But his body itself was being stopped. It was a rather strange combination, and he reckoned he could test more.

Seeing as he had a lot more time till the analysis of the system would be complete, Lin Wu decided to just do this.

And just like that several hours passed and Lin Wu did a slew of different tests with the barrier, always making sure that he did not go beyond the threshold at which the alarm formations would activate.

"Goddamn, it really worked!" Lin Wu exclaimed.

He had done something that he had randomly tried. He never expected it to work, but it did. He didn't know why, but he didn't care for it.

In front of Lin Wu, a small fingernail sized hole had been opened up on the barrier. The edges of this hole glowed with a green-blue light which was nothing but the spirit Qi modified due to the undaunted sapphire body art.

"Ahaha! Now I know what to do. System, record these results and see if they can be extrapolated on a larger scale without the alarm getting activate." Lin Wu said.

~Ding~

TASK ADDED: Barrier penetration test

TIME REQUIRED: 5 hours, 48 minutes, 9 seconds

"Hmm, this should be enough till we complete the duel." Lin Wu said, before checking the timer for the duel. There was still some time left to it and Wang Xiong was also busy in his preparation.

Lin Wu extended his spirit sense and checked the condition of the man in his residence, finding him to be in the same condition as he had left him. With Lin Wu's long ranged spirit sense, it was easy for him to now keep track of things that were a bit far from him.

He took a look around the nearby area as well and while he was doing so the system gave him another notification.

~Ding~

TASK COMPLETED: Formation array analysis

DATA BANKS: Updated

NOTIFICATION: Please check the relevant window for details

——

"Perfect! Just in time." Lin Wu spoke, feeling pleased before opening the window with the new data.

"Oh? This set up seems quite familiar to me…" Lin Wu muttered upon seeing the information about the Qi gathering formation that the sect used.

Essentially, the Qi gathering formation array worked quite similar to how the power grid worked in his past life. The Qi would be gathered from various sources, whether it be the air, spirit Qi springs or the spirit stone mines, and would then be guided to the reservoir.

These sources were like the power plants that generated electricity. And like them, they didn't always operate at their full potential as it would be damaging to the infrastructure instead.

Currently, Lin Wu saw that all of them were operating on fifty percent capacity and this was more than sufficient to supply spirit Qi to the entire sect. And not just this, even the reservoir had enough spirit Qi that it could independently supply spirit Qi to the entire sect for a month before it would get depleted.

This gave him a lot of leeway in making his later plans.

"Hehehe… time for a heist…"
