Survival at Sea: I Became Number One by Growing Mushrooms

She couldn't believe that the difficulty here would be easy, and even suspected that the Dark God had arranged a backup plan.

Therefore, she still needs to make sufficient preparations before entering, especially for the purification potion. She needs to slightly change the potion's effects so that she doesn't lose half her life every time she purifies the pollution.

Looking at the materials she had, she could try to re-adjust the purifying potion recipe with mugwort. She could use whatever herbs she had; with the current conditions, why be picky?

Moreover, mugwort is a unique herb of these islands. It was not even in Xu Jiawei's previous herbal encyclopedia. It must be a special plant that was nurtured in a special environment. It can nurture light even in darkness, just like Xu Jiawei, who was corrupted by darkness and turned into a light-attribute plant. This plant mutated because it was stimulated by the dark attribute.

Using this herb to make potions might have unexpected effects. She retreated back outside the cave, set up the crucible, took out several herbs that she intuitively felt were a good match for mugwort, and began experimenting. As expected, the first two attempts failed, but the third one produced a completely new potion.

Under normal circumstances, it would be impossible to prepare the medicine so quickly. All prescriptions require hundreds or thousands of experiments. However, Xu Jiawei has a strong sense of perception. With her super sixth sense, she can always find the ingredients that match the main herb among a pile of herbs. Moreover, Xu Jiawei's premonition has been enhanced now.

The first two failures were simply due to incorrect heat and dosage. Once the heat and dosage were adjusted on the third attempt, the medicine was successfully prepared.

Xu Jiawei drank a whole bottle and used it as an experiment to see the effect. The medicine was very mild, which meant that its purification speed was slow. However, the medicine had a special function: its greatest function was to prevent the invasion of pollution and form a protective film in the body.

This was the biggest surprise; the medicine's effects completely exceeded her expectations.

Once the new potion was prepared, she immediately brewed several batches, put a few bottles in her pocket, and the rest into Rainbow's mouth before re-entering the cave. With these potions, she felt confident in purifying the pollution.

But one shouldn't speak too confidently, lest one be proven wrong again. Xu Jiawei cautiously entered the cave. The further she went in, the thicker the fog became, almost as dense as the fog at the Spring of Death. Although the pollution there wasn't high, the mental pollution was terrifying, especially the mental effects of the Spring of Death, which were impossible to guard against.

This mainly erodes the body. Although the dark attribute itself has the effect of eroding the spirit, it is definitely not comparable to the Spring of Death.

As they ventured deeper into the cave, the surrounding fog thinned considerably, revealing crystal-clear skies. However, the dark energy in the air became increasingly active, as if it had been condensed.

The dark energy seeped into her body through her pores. Xu Jiawei frowned and drank another bottle of purification potion.

Only after my skin formed a protective barrier did I go inside.

We've arrived at a black hot spring that's bubbling and gurgling?

This must be a hot spring; it's bubbling. It looks more like a thick, bubbling medicinal liquid in a crucible.

What is this pot, no, this pool of black water?

[Ding! Congratulations, player, you have entered a top-tier pollution source. The system has provided purification equipment. Purification will take three hours. Please protect your equipment during this time. If the purification equipment is destroyed, purification will fail. If successful, you will receive a high reward.]

The system voice sounded, and Xu Jiawei got into a defensive stance. The ground shook violently, indicating that there were quite a few things coming. The hole was only so big; could they get in?

Xu Jiawei was skeptical at first, but she soon stopped doubting because these monsters were all teleported there via a teleportation array.

A teleportation array opened, and a steady stream of mutated creatures poured out, quickly filling the cave.

After the cave was filled, the teleportation array did not disappear. Instead, a continuous stream of creatures poured out. Before Xu Jiawei could deal with the mutated creatures, two more teleportation arrays opened, making the cave even more crowded.

Meanwhile, the mutated creatures behind the teleportation array continued to crowd in.

As expected of a top-tier source of pollution, is she employing a swarm tactic? It seems Xu Jiawei is playing tower defense now, except the number of monsters spawning is a bit excessive.

Her photon meteors never stopped. Even though these monsters were burned by the flames of the photon meteors, they still stubbornly rushed towards the pool, only to die halfway there and be cleared out by the system.

Xu Jiawei had originally planned to use these corpses as a defensive line, but they were cleared out. She was really grateful to the system. She didn't need the system to be so diligent; it was too diligent. But what was there to say to this electronic machine, the system?

Xu Jiawei is still barely holding on, but the strain is immense.

She barely managed to maintain a balance between income and expenditure by absorbing energy, and her experience bar was also increasing rapidly. However, leveling up was not very useful now. She was barely at level 70. Even if she continued to level up to level 80, she would still be stuck in experience and level.

She no longer has such a strong desire to level up.

After two and a half hours of monster invasion, not a single wisp of magic in her body was her own; she was just numbly releasing skills, absorbing energy, and casting spells.

After two hours, the number of monsters dwindled, probably because she had already killed them all, causing a shortage of mutated creatures.

Two and a half hours later, the three teleportation arrays stopped producing magical beasts and seemed to be stunned. After waiting for two minutes, a dozen or so priests followed by seven or eight high priests were teleported in.

They seemed quite reluctant, because they had also heard of this player's fearsome reputation. The high priests and even bishops over there had been killed by this female killer. It was said that this demon had even killed the avatars of gods, which was truly terrifying. The priests who had fought against this female killer were left without even ashes.

Several high priests warily surrounded Xu Jiawei, who also became serious. Were they starting to fight elite monsters?

While dodging, Xu Jiawei unleashed her skills, alternating between Photon Meteor and Light Spore, and also releasing a Light Cocoon to protect her vitals from attacks. Now, Xu Jiawei was still able to handle the siege of seven or eight high priests with ease, and she was very satisfied, as she had indeed become stronger again.

Xu Jiawei seized the opportunity, found someone isolated, and unleashed a barrage of skills, resulting in casualties among the high priests.

However, at this moment, the teleportation array lit up again, and ten more high priests poured in, followed by a figure that was both unexpected and expected for Xu Jiawei.

I didn’t expect the God of Darkness to think so highly of her, even sending a bishop. But the first to tenth bishops were all here before, so which bishop is this?
