High-level martial arts: Contract cashback, invincible starting from the Zerg.

There are five days left until the Dao Gate of the Baifei Dimension opens.

Chen Feng opened the "Bai Fei" APP, wanting Bai Fei to learn about the Ziwei Insect Clan before she descended upon the Great Xia Dynasty.

...

At this moment, Bai Fei was watering plants in a green garden.

This is the exclusive breeding area deep within the "Youman" class-3 Zerg warship under Bai Fei's command. The breeding area is isolated from the outside world by a semi-transparent chitinous biomembrane.

The plant was no ordinary grass or tree; its leaves occasionally shimmered with a cold, metallic sheen, and its vines were covered with fine patterns of the White Flying Insect Clan. Its finger-thick roots were intricately embedded in the White Flying Insect Clan's insect nests and fungal carpets.

It looks like some kind of static Zerg unit.

Bai Fei, dressed in white queen's armor, stood in front of a clump of plants about half her height, holding a biological infusion device in her hand. The pale green nutrient solution flowed into the soil at the roots of the plants through the infusion device, and the soil immediately showed a faint pulse of life.

A subtle ripple suddenly appeared in the space.

Bai Fei paused slightly on the wrist, but a faint smile appeared on her lips.

As the light faded, Chen Feng's figure emerged from the spatial fluctuations.

His gaze immediately swept across the entire green garden, and he turned around to look with a hint of doubt.

Only then did they see Bai Fei, who had been hiding quietly, seemingly trying to scare Chen Feng from behind.

"What are you doing?" Chen Feng asked, somewhat surprised.

Bai Fei then peeked out from behind the waist-high crystalline foliage, her purple ponytail immediately dotted with tiny pale green spores.

Her brows and eyes, which were usually covered with a layer of frost, now hid a smile. Even though Chen Feng had caught her red-handed, she was not flustered, but instead showed a bit of smugness.

"I was going to wait until you searched for a while before speaking, to see your reaction..."

As Bai Fei spoke, the pale white light patterns on her Queen's Armor flowed slightly.

The gentle light softened her otherwise cold and sharp features.

Bai Fei is now the Bai Fei Zerg Queen, sitting atop hundreds of thousands of Zerg.

It's normal for her to exude an aura of intimidation, but in front of Chen Feng, she seemed to have shed that heavy shell, and even her eyes were filled with a subtle warmth.

Chen Feng chuckled: "Strange? Why aren't you calling me 'senior' anymore?"

"Huh?" Bai Fei blinked, glancing down at the thin vines winding along the edge of her boots.

The vine seemed to sense its owner's emotions, gently brushing a tiny, crystalline leaf against her boot, as if cheering her on.

Bai Fei looked up at Chen Feng.

The smile on his face faded slightly, replaced by a more straightforward seriousness.

"That was in the past. Back then, I had just taken over the Bai Fei insect clan's legacy, and I needed your help to get through many things. It was only right that I called you 'senior'... But now I only want to call you by your name," Bai Fei said with a gentle smile.

"Haha, fine then. We are indeed close enough, so it's understandable that you don't call me senior."

"Hmm~~"

"Bai Fei, the main reason I came here is to show you some information about the Purple Insect Clan." Chen Feng directly transmitted the data package from the Lucky Contract System to Bai Fei.

"Okay, I'll have my men make the necessary preparations."

The two had finished their business.

Chen Feng's gaze immediately swept over the various green plants around the garden.

"Oh, by the way, why do your plants have teeth?"

Chen Feng looked at the patch of plants in front of him that were as tall as a person's leg.

The edges of the leaves are neatly arranged with a ring of sharp angles as fine as needles, and the waving vines are embedded with countless tiny scales that are barely visible to the naked eye. A light touch will cause them to release a very faint corrosive smell.

"It's so corrosive?" Chen Feng asked with a hint of surprise. "This thing doesn't seem like something the natives of this hunting world would use."

Bai Fei chuckled softly upon hearing this and stepped forward to the plant.

When the Queen's Armor brushed against the plant, the serrated leaves seemed to recognize their owner, and they all closed up in unison, even the vines drooped obediently, looking like a shy little plant.

The sharp edge they had displayed when fully armed just moments before was completely gone.

"Normally speaking, the Zerg cannot tame plants. The Zerg's original genes are biased towards highly active carnivorous evolution. In the past, some high-ranking Zerg lords tried to forcibly fuse the genes of the two, but in the end, either the plant's genes disintegrated and it died, or it mutated into a mindless mutant, making it impossible to form a controllable fighting force."

Bai Fei paused, a faint white light emanating from her fingertips, as she gently touched the plant in front of her.

Following the direction her fingertips touched, the thick root beneath the crystal leaf slowly rose from the insect nest's fungal carpet. The fine, hair-like roots swayed gently in the air, as if summoned by some kind of call, moving incessantly with the light from Bai Fei's fingertips.

"However, the Leviathans possess ecological-level gene-editing capabilities. Once the Warbringer reaches level 5, I can embed Whitefly Zerg sequence fragments into the genetic chains of plants, essentially rewriting their 'underlying growth logic.' And these are the first generation of combat plants I cultivated—I call them Crystal Vines."

Chen Feng immediately became interested.

Ordinary Whitefly Zerg warriors, whether they are scouts, heavy infantry, or acid cannon worms, are all standard combat units composed of flesh and chitinous exoskeletons.

However, Zerg units possess life energy signatures stronger than those of ordinary animals, and even humans, making them easily targeted by enemy detection systems and extremely vulnerable to detection during infiltration operations.

But the crystal vine body that Bai Fei mentioned is different.

They are based on plant tissues, absorb nutrients through roots and transmit information through spores. They lack concentrated organs and energy cores, making them almost undetectable by conventional detection methods.

Bai Fei pointed to the insectoid fungal carpet in front of her, and several finger-thick main vines began to move slowly.

Within moments, the crystal vine obediently moved to the insectoid territory and once again entered a state of standby.

"Unlike Zerg warriors, Crystal Vortexes can manipulate micron-level cell growth. Whether it's rock crevices, metal welds, or enemy fortifications' pipelines and ventilation ducts, given enough time, they can penetrate them. Their penetration efficiency is several times higher than that of scouts, and they are extremely difficult to detect completely."

Bai Fei explained.

"The most crucial point is that they can also symbiotically cover the Zerg warriors, secreting a biological armor-healing fluid, which can further enhance the camouflage effect of the Zerg warriors. Some units can also use them for climbing, binding, and venom shooting, which is equivalent to adding an extra combat power module to these combat units."

Bai Fei withdrew her hand, and the roots and vines of the crystal vines fell back into the insect hive carpet, quietly absorbing the energy within the insect carpet.

Upon hearing about the combat modules created by Bai Fei, Chen Feng looked at the quietly growing crystal vines in the garden with a face full of admiration, and for a moment he didn't know what to say.

"Bai Fei, you are a genius. You can actually tame plants into such ruthless creatures."

After being praised by Chen Feng.

Bai Fei smiled, quickly regaining her queenly composure.

"They are only the first generation of crystal creep. After I have reviewed the data on the Purple Creeper you brought, I will adjust their genetic sequences to allow them to evolve into units that can counter the Purple Creeper.

"Okay, I'll wait for your good news."

"Chen Feng, there are a few more advanced varieties and some delicious food inside. Let me show you."
