Cave Refuge

As the flood receded, the former Plantation Area on the mountain had been abandoned, and the members of those powers had been incorporated by the Officials.

Under the implementation of wartime regulations, the vast majority of survivors in Pengcheng had been organized into numerous crop production teams, adding bricks and tiles to resume food production.

Within a few days, Dong Tianyu's cultivation had reached the full circle of the twelfth layer of Qi training. The only two choices in front of Dong Tianyu were to continue accumulating strength or to break through to the Foundation Building Stage.

Of course, Dong Tianyu's choice was very clear, he must break through. Only by breaking through the Foundation Building Stage could he truly embark on the path of longevity.

However, there were several different ways to make the breakthrough.

The most difficult way was to break through on one's own, relying on the Spirit Power accumulated in the body, forcibly refining mental power, and transforming it into Divine Sense.

If one's mental strength is stronger, the more Spirit Power required. However, the Divine Sense obtained after transformation is also stronger.

However, this method is not suitable for Dong Tianyu. After all, since the beginning of his cultivation, Dong Tianyu has been using the system's help and did not intend to continue accumulating Spirit Power.

Therefore, if he used this method to break through, the success rate of Dong Tianyu's breakthrough would be almost zero.

The second method, which is often chosen by ordinary people in most novels or TV dramas, is to use the Pill of Foundation Building.

Normally, during a Qi training phase's breakthrough to the Foundation Building Stage, due to the issues related to the transformation of Spirit Power, the use of ordinary pills can affect refining and even interrupt the refining process.

So under normal circumstances, pills cannot be used when breaking through during the Qi training phase. But there are exceptions, such as Foundation Building Pills, which are not names for specific pills. Instead, it is a generic term for a particular type of medicine. Any medicine that can be used during a breakthrough can be called a Foundation Building Pill.

However, there are very few types of this medicine, and to test its medicinal properties, Qi-training individuals who are preparing for breakthrough must be chosen.

It's important to note that not only will a failed breakthrough affect the success rate of the next attempt, but it can also damage one's mental strength. Thus, few people are willing to volunteer to test the medicine.

As a result, in most worlds, there is only one way to refine the Foundation Building Pill, and the formula for the medicinal materials, and even the properties of the medicinal materials used in each world, are different.

Unfortunately, Blue Star is not in a declining spiritual era but in an era devoid of Spirit Power. There is no natural growth of spiritual herbs in the outside world, let alone an attempt to refine a Foundation Building Pill, let alone ordinary elixirs.

However, what gave Dong Tianyu the confidence to prepare for his breakthrough was the fact that Survival Points were an omnipotent existence in his Cave Mansion.

With Survival Points, Dong Tianyu had an extra choice when preparing for a breakthrough, that is, using Survival Points to replenish Spirit Power. This method produces Spirit Power that is even purer than that obtained by using the Foundation Building Pill.

He found that even if his Spirit Power was exhausted, he only needed to consume three Survival Points, and his depleted Spirit Power would instantly be replenished.

For Dong Tianyu, who has been saving his Survival Points and not using them until now, the over three thousand Survival Points should be more than enough to use during his breakthrough. After all, he was only breaking through the Foundation Stage and not crossing a heavenly tribulation.

Dong Tianyu sat in the Hall of Longevity, concentrating and holding his breath, setting up to automatically use Survival Points for replenishment when his Spirit Power was less than 30%.

After getting ready, Dong Tianyu began to stimulate all the Spirit Power in his body, surging towards the Sea of Consciousness within his brain.

The Sea of Consciousness is not a physical organ but a special space embedded in the human brain, like a sub-space.

Everyone has a Sea of Consciousness, and everyone's Sea of Consciousness is almost the same size at birth. It is the base of mental power and also the storage point for memory.

When learning new knowledge, the Sea of Consciousness will expand,

Having experienced some events, the Sea of Consciousness will expand,

After making new friends and interacting with them, the Sea of Consciousness will also expand,

Even without doing anything, as time passes, the Sea of Consciousness will expand.

This is what people mean when they say that as they grow older, they become more mature.

It's not easy to describe in words what mental power actually is, but everyone can detect from the other's expression whether their mental power is active at this moment or not.

Although everyone can see at a glance whether the other is energetic, few people can express it with other specific words. This is also a kind of instinct.

Mental strength is an invisible energy. The purpose of building a foundation is to refine this invisible energy. It remains invisible, but it can influence other invisible or tangible things.

To put it simply, why are the cultivation techniques of the Qi training period and the Foundation Building Stage different in many novels?

The Qi training period relies entirely on the body to absorb the surrounding Spirit Power, which is like fishing; one can only wait passively.

But, after refining mental strength, one can actively capture the surrounding Spirit Power, which is equivalent to casting a net. Although the goal of both sides is to absorb Spirit Power, there is a significant difference in efficiency between the two.

Mental energy after refining not only affects the equally invisible Spirit Power, but also the tangible things, such as the Manipulation technique that can only be practised during the Foundation Building Stage.

You may not understand what the Manipulation technique is based on its name, but one of its extensions is very famous, that is, Sword Control technique.

The essence of the Sword Control technique is actually the Manipulation technique. Once learned, not only can you control the flight of a sword, but you can also control the flight of other Magical Weapons.

Apart from refining the physical body, most other cultivation systems require refining of mental power.

For example, the Meditation method for mages, which after learning, uses mental power to capture the surrounding elements.

For instance, warriors refine combat energy, which likewise uses mental power to capture free combat energy in the air.

Ninja's Chakra cultivation, although not capturing energy in the air, but uses mental strength to squeeze physical strength to produce Chakra, so it also consumes mental power.

Even the Borrowing system of magic reputed to not need accumulation of Magic Power, also needs to increase the mental power limit to borrow more Magic Power.

Therefore, in most cultivation systems, mental power plays a pivotal role.

The way to initiate a Foundation Building Stage is different from the normal cultivation method; one only needs to operate the Spirit Power inside the body and directly pour it into the Sea of Consciousness.

There may be some more practical skills in this process to reduce the loss of one's Spirit Power during the pouring process, but Dong Tianyu, who has not yet found a mentor, does not know this. He can only use the most primitive and most aggressive way to break through.

As the Spirit Power entered the Sea of Consciousness, the Spirit Power in Dong Tianyu's body was like a dam that had burst, and the Spirit Power in his body decreased rapidly.

However, the Sea of Consciousness seemed to be a bottomless hole, even though more than half of Dong Tianyu's Spirit Power had been exhausted, there was no change inside.

The lowest warning line for Spirit Power set by Dong Tianyu was quickly breached. The Data Layout, which only changes once a day when Survival Points are obtained, began to fluctuate rapidly on the line representing Survival Points.

Although it decreased by only 2 Survival Points each time, the frequency of the decrease was exceptionally high.
