Survival for All: I can deconstruct projections and synthesize everything.

The concentration of metal-elemental spiritual energy on the second floor is five times higher than that on the first floor.

If you cultivate on the second floor, your cultivation speed for the metal element will be five times faster, while other spiritual energies will not be able to improve.

Then, Lin Xiao quickly went up to the 3rd floor, the 4th floor, and all the way to the 6th floor, and found that from the 2nd floor to the 6th floor, the concentration of spiritual energy was in the order of metal, wood, water, fire and earth.

"It seems that floors 2 to 6 are for cultivating a specific type of spiritual energy, while floor 1 is for all-round development!" Lin Xiao thought to himself.

In fact, these changes to the safe house already made this upgrade worthwhile, but the upgraded safe house is not just that.

After leading Zhuge Duo and the others on a brief tour, Lin Xiao sent them away.

As for whether Zhuge Duo envied Lin Xiao's safe house, Lin Xiao doesn't know for the time being.

After Zhuge Duo and the other two left, Lin Xiao opened the Fog System to check the message that had just been displayed.

[Since the survivors have upgraded the safe house using Five Elements Crystals, they can now use a small amount of Five Elements power within the area of ​​the safe house.]

The various forces governed by the Five Elements must be explored by the living themselves.

The fog system only issued these two notifications, and then there were no other messages.

Lin Xiao frowned, then began to study these words.

At first, Lin Xiao did not notice any other changes.

However, when he stepped out of the safe house, he suddenly noticed a different sensation in the air outside the safe house, which was his territory.

Lin Xiao carefully examined himself and discovered that this feeling was exactly the same as the feeling he had in the safe house.

"Could it be that the Five Elements spiritual energy already exists in my territory?" Lin Xiao asked in surprise, sensing the Five Elements spiritual energy that appeared around him.

Then, with a thought, a metal-based rule focused on killing suddenly appeared at Lin Xiao's fingertips.

"It really is the rule of the metal element?" Lin Xiao asked in surprise.

However, the current power of the metal element is very weak.

If the power of the Frost Rule controlled by that Elder Han is like the Yangtze and Yellow Rivers, then the power of the Rule controlled by Bai Qi is like a small stream.

Lin Xiao's current metal-elemental rule power is equivalent to a regular household faucet running water, but not fully open, only half open.

But as the saying goes, whether it's the Yangtze River, the Yellow River, a small stream, or water from a tap, they can all quench your thirst.

Therefore, even if Lin Xiao only grasped this trace of the power of rules, he could still crush a fourth-order being who had no power of rules.

Next, Lin Xiao tested the power of the rules of the other four attributes, and finally confirmed the effectiveness of the various rules.

The metal element power he has just mastered is primarily for killing; among the five elements, its offensive power is the strongest.

The following wood-elemental power is primarily for healing and treating poisons.

The power of the water system rules is primarily for purification.

It is important to note that the healing power of the wood element can only heal injuries, while the power of the water element can purify some negative effects, such as curses, plagues, poisons, etc.

The power of fire is primarily about burning, explosion, or, in other words, extremely wide-range destructive power.

The final element of Earth's power is characterized by its solidity, protection, and gravity.

Of course, the uses of the power of rules mentioned above are only the most basic uses.

Just as the power of the wood element can summon vines out of thin air to bind something, the power of the water element can also be extended into the power of the ice element, and so on.

The use of the power of rules is not so rigid; what is needed to use them is one's own imagination.

For example, the power of the metal element, which is supposed to be primarily offensive and lethal, has been manipulated by the King of Gold into something more like gold.

If Lin Xiao doesn't use his clones, he can only use one type of rule power at any given time.

Lin Xiao is currently unable to combine two or more rules of power for use.

Even if he uses the Spirit Pillar to summon a clone, he can only control another kind of rule power through the clone.

What Lin Xiao regrets even more is that the power of the Five Elements rules can only be used within his territory.

However, if Lin Xiao leaves his own territory and enters another territory, the power of the rules he currently possesses will become ineffective, unless Lin Xiao can bring his enemies to his own territory.

This could be considered Lin Xiao's only regret.

However, this also greatly improved the safety of Lin Xiao's territory.

Furthermore, based on the changes in the safe houses and territories, Lin Xiao can already deduce the changes in the territories of those survivors who have already upgraded their safe houses.

Moreover, the fact that so many people have already upgraded their safe houses, yet no news has been sent out, is enough to show that everyone is making a fortune in silence.

However, those who only used a single crystal to upgrade their safe house level did not receive as many rewards as Lin Xiao.

As for the next upgrade to the safe house, Lin Xiao's eyes darted around before turning to the Fog System.

[Current level: Five Elements Crystal Safe House (Special). To upgrade to Five Elements Crystal Safe House +1, you need 10,000 Source Crystals, 10,000 Stones, and one of each of the Five Elements Crystals.]

"I didn't expect that the next upgrade would require Five Elements Crystals." Lin Xiao pondered for a moment as he looked at the requirements for the next upgrade.

However, obtaining those Five Elements Crystals is extremely difficult, and many people will likely be stuck at this stage for a very long time.

As for Lin Xiao, apart from the crystal stone whose deconstruction time has not yet been reached, he can project one of the other four types of crystal stones at any time.

For other survivors, there might not be much they could do, but for Lin Xiao, it was simply a matter of waiting a few days.

With a single step, Lin Xiao arrived in front of the Great Elder of the Grass Spirit Clan.

At this moment, the Grand Elder and the members of the Grass Spirit Clan were all excited as they felt the wood-attribute spiritual energy permeating their territory.

Since the Grass Spirits can only absorb wood-attribute spiritual energy, other types of spiritual energy have little effect on them.

However, at present, what Lin Xiao releases through the safe house is the Five Elements Spiritual Energy, which contains all five attributes, rather than a single type of spiritual energy.
