With their current level of cultivation, after absorbing these energies, some of them will most likely be able to advance.

When breaking through the level barrier, some people's supernatural powers will fluctuate greatly, which will affect the people around them.

Wen Yubai thought about it, then quietly used his supernatural powers to condense metal plates to separate them, giving each of them a small compartment.

Wang Yizhen was the most important, because Wen Yubai could feel her strong desire, so he taught her how to feel the energy and how to guide the energy to impact her meridians. This method of opening her meridians would be very painful, and she would probably groan in pain.

However, as long as she can hold on, even if she does not activate her superpowers in the future, her physical fitness will not be much worse than that of a person with strength superpowers.

The friends were all concentrating on meditation and cultivation. In this environment where danger could be present at any time, Wen Yubai naturally could not be like them and drank the crystal core energy pill to concentrate on meditation and cultivation.

So she drank the remaining energy pills, then slowly squeezed the other half of the solvent strain into juice and threw a crystal core into it.

Then she drank one-fifth of the dose, a dose that she could absorb without having to concentrate fully.

After drinking the juice that melted the crystal core, the familiar feeling quickly spread throughout the body and felt very comfortable.

This mutant plant, which was officially named the solvent strain in the previous life, is not poisonous, but if eaten directly, it will be so sour that people's teeth will fall out.

But the amazing thing is that when the rhizomes of the solvent strain are squeezed into juice and the crystal core is dissolved in it, it becomes a sour and sweet energy supplement. Although it is not very delicious, at least it is not sour enough to make your teeth fall out.

However, no one would complain that this energy agent tastes bad, because this crystal core energy agent can assist psychics in their cultivation and strengthen the physical fitness of ordinary people.

The energy in the crystal core is too violent. If humans take it directly, unless a high-level psychic takes a low-level zombie crystal core, for example, a third-level psychic takes a first-level zombie crystal core, most psychics will not be able to withstand the violent energy impact in the crystal core.

At that time, the psychic will injure his meridians because he cannot absorb and dissolve the explosive energy in time. In mild cases, it will lead to a regression in his psychic cultivation, and his cultivation will stagnate before he is healed. In more serious cases, he will turn into a zombie.

The solvent strain can dissolve the crystal core and lock the energy in the crystal core in its juice. Psychics can take a small amount of crystal core energy agent to practice, which is equivalent to a high-level psychic taking a low-level crystal core, so there will be no unbearable consequences.

Wen Yubai's gold-based ability had already reached the second level of perfection. When she drank a cup of crystal core energy potion every ten minutes, she had no barriers as she had already been promoted to the third level once, and her gold-based ability was quietly promoted to the third level.

Her mental power only became more profound, comparable to the progress she made after ten days of practice, but it failed to break the barrier to advancement like the gold power.

After the promotion, Wen Yubai restrained his breath and did not drink the remaining energy pills. He checked on Wen Yuxian's condition.

Wen Yuxian didn't drink the strengthening potion produced by the system for nothing. Although her water-related ability potential was originally very low, under the strengthening effect of the strengthening potion, coupled with her continuous training and killing of zombies during this period, her physical fitness has increased by leaps and bounds, and her water-related ability has reached level zero perfection a few days ago.

Less than half an hour after drinking the energy dose, Wen Yuxian's water-based ability was upgraded to level one. With the help of the energy dose, her momentum continued to increase.

Zhao Xuehui's system ability had been promoted to the early stage of level one three days ago. Judging from her current momentum, after she absorbs the energy agent, her cultivation level will probably be promoted to the middle stage of level one.

As for Yu Baolian and Ye Yifen, although they have not reached the limit for promotion this time, they should be able to do it after drinking one or two more energy shots.

The one who surprised her the most was Wang Yizhen. It was estimated that this girl had always been eager to stimulate her supernatural powers. Later, she was brought here by Zhao Xuehui. The fact that she was the only ordinary person among the six people stimulated her even more.

Wen Yubai gave her double the dose that an ordinary person could drink, just to help her.

Wen Yubai was confident that he could protect this girl and prevent her from turning into a zombie after failing to absorb energy. But he didn't expect that her endurance was so strong that she could endure the pain when the energy opened up her meridians without making a single painful groan from beginning to end.

But this pain was worth it. Half an hour later, Wen Yubai felt that just as Wang Yizhen wished, she was now emitting a faint aura of supernatural powers.

It's just... Wen Yubai frowned slightly. She felt that Wang Yizhen's momentum had weakened again. This was obviously due to lack of stamina. So she picked up the remaining energy pills, put them next to Wang Yizhen's mouth and said, "Open your mouth and I'll feed you."

In such cold weather, Wang Yizhen was sweating all over due to the pain, and her lips were bitten until they bled, which shows how much pain she was in.

As soon as Wang Yizhen heard Wen Yubai's voice, she immediately opened her mouth and fed Wen Yubai the energy pill.

After Wang Yizhen drank the energy dose, the supernatural aura on her body, which had been gradually weakening, gradually became stronger again.

Wang Yizhen was in good condition and stable, so Wen Yubai sat back at the table, playing with a crystal core in his hand, with a rare joy in his eyes.

At that time, humans did not know how precious the first-level crystal core was. After most zombies were promoted to level two or above and level one zombies became extremely rare, they realized the preciousness of the level one crystal core.

Level 1 crystal cores are attributeless and can be used for any superpower, even mental powers.

Although the effect of improving mental power is only one-third of that of gold-type power, Wen Yubai does not despise it at all. Instead, he is determined to collect as many first-level crystal cores as possible in the next few months.

Because after the zombies are promoted to level two, the crystal cores have attributes, including colorless system crystal cores, white gold crystal cores, green wood crystal cores, blue water crystal cores, red fire crystal cores, yellow earth crystal cores, black space crystal cores, and purple spirit crystal cores.

If a psychic wants to use a crystal core to practice, he must use a crystal core with the same properties, otherwise the consequence will be damage to his meridians and a regression in his cultivation.

Among them, the most powerful zombies are those with system abilities, accounting for almost half of the zombie population, and the rest are those with natural abilities. There are very few zombies with space abilities and spiritual abilities, accounting for only one ten-millionth of the zombies.

Therefore, in their previous lives, psychics and space-related psychics could hardly get crystal cores that suited them, and they had to rely on their own practice to advance, so their advancement was much slower than that of other psychics. Only then did they realize how rare a first-level crystal core was.

Although the energy that the first-level crystal core can provide will become less and less as her cultivation level goes up, she can make up for it with quantity if the quality is insufficient. As long as she has enough first-level crystal cores, it will be enough for her to cultivate to level five or six.

Thank you Yin Zixia for the monthly ticket.
