Under normal circumstances, Su Chen would use some of his due system permissions in exchange for security, which is not a cost-effective deal.

But the current situation is special. Su Chen needs the girl's help very much. Even if the price is high, he cannot refuse.

Seeing Su Chen agree, the girl quickly stood up and thanked her, and then took out the old blood-drawing equipment from the thatched hut.

Su Chen's face trembled slightly. This blood-drawing device had been used countless times, and even though it was polished to a shiny appearance, it still made Su Chen feel disgusted.

When the girl saw that Su Chen looked unhappy, she half-knelt on the ground without saying anything and held out the blood-drawing equipment with both hands.

Without Su Chen's blood, she would have lived for at most half a year. For the sake of her life, she had to lower her body.

Su Chen took a deep look at her, took the blood drawing equipment with one hand, and helped her up from the ground with the other hand.

"Pack up the supplies you need to bring and come with me. I have better medical equipment."

Su Chen didn't have a deep understanding of purebloods and mixed-races, but he was convinced that the blood-drawing equipment in front of him had been used by many mixed-races and had not been sterilized and replaced regularly.

Su Chen did not dare to give the girl a blood transfusion at the risk of being infected with an unknown virus.

As for inviting the girl to go to the K1 base with him, it was a choice he made after careful consideration.

With a happy face, the girl bowed deeply to Su Chen, picked up the long bow on the ground, and said with a smile: "It's enough if you have it."

"Bring all you can eat with you." Su Chen wasn't sure when he would come back next time, so it wouldn't hurt to bring more food back for storage.

The girl did not refuse. She spent half a quarter of an hour packing all the food, stuffing part of it into Su Chen's backpack, and putting the other part into a bamboo basket and carrying it on her back.

The girl had quite a lot of food stored, and the food for purebloods was enough for Su Chen to eat for a week.

Feeling that the weight on his shoulders has increased, Su Chen's depressed mood has improved.

Not long after, Su Chen stepped into the mysterious forest again.

The thick fog quickly obscured Su Chen's sight. An ordinary creature would have a high probability of losing its way even if it lived in this forest for decades.

Su Chen didn't. He held the map mode in his hand. From the K1 base to the thatched house at the foot of the mountain, the geographical environment along the way was entered into the map by Xiaosha.

Coupled with the route code marked by Su Chen on the way, he only needs to return along the original route.

In the small clinic at the K1 base, according to the girl's request, Su Chen gave her 600ml of blood.

The blood transfusion process was simple and long. Su Chen didn't feel relieved until the system prompted that the girl's mind had been successfully restrained for killing.

"Warning! There is an invasion of unidentified creatures." All the alarms in the K1 base sounded at the same time.

Su Chen, who had just finished the blood transfusion and had not had time to catch his breath, was startled by the sudden alarm sound.

The next second, Su Chen, who realized the seriousness of the problem, shouted softly: "Little K, retrieve the location of the intruder."

"The retrieval failed. The intruder is suspected to have invisibility and cannot lock the location." Xiao K responded quickly.

Su Chen frowned. He took out the dagger tied to his waist and looked at the tempered glass door of the private clinic with a wary expression.

At the same time, the girl pulled out the needle, grabbed the long bow on the table with her right hand, and watched her surroundings vigilantly.

There is only one entrance and exit to the private clinic. If an invisible creature really wants to attack him, it will inevitably push open the half-open glass door.

Su Chen waited for a moment and saw that the glass door was not pushed open by the unknown creature. He reached out and pulled the small k (holographic display), clicked on the small k and photographed the so-called invisible creature.

The image captured by the camera is very clear. The invisible creature Little K mentioned was very different in size from the mysterious blood rat he encountered last time.

As for its appearance, it’s hard to describe. It feels like a combination of an African leopard and a monitor lizard.

This strange creature seems to have improved the lizard's ability to change color, creating an invisibility effect that confuses vision.

"It's the Hidden Leopard." The well-informed girl only glanced at the screen and said the name of the strange creature.

"How to hunt?" Since the girl knows him, she must know the method of hunting.

"The Hidden Leopard's invisibility has a fatal flaw. It activates every time it breathes, and it cannot remain invisible during combat. It can be hunted by just listening to its footsteps and following its instincts."

"By the way, most hidden leopards can't breathe for more than two minutes." The girl added.

The girl did not provide a good hunting plan, but after learning about the hidden leopard's flaws and its size from her, Su Chen believed that it would never be able to break open the glass door silently.

"The location of the hidden leopard has been captured, and the latest surveillance footage has been provided." Little K suddenly prompted.

Su Chen glanced at the automatically switched surveillance screen and confirmed that the hidden leopard was not far outside the door.

"Get ready for battle." Su Chen said subconsciously.

The girl's combat experience and reaction were much faster than Su Chen's. She had already drawn her bow and aimed it at the gap in the glass door. As long as the hidden leopard dared to push it open, she would definitely hit the target with her archery skills.

The hidden leopard's prediction of danger is much better than that of the mysterious blood rat. It seemed to know the power of the long bow in the girl's hand. It did not push open the glass door, but stood behind the glass door and quietly watched the prey, waiting for the most suitable hunting opportunity.

opportunity.

Su Chen waited patiently for half a minute. Seeing that the hidden leopard was still reluctant to open the glass door, he concluded that it had left and began to think about how to lure the hidden leopard to attack.

Just when Su Chen's thoughts slowed down his movements and reactions, Yinbao suddenly opened the glass door and rushed in.

Although the Hidden Leopard can become invisible, its attack method is single. Seeing that Su Chen was distracted, he knew that if he didn't take the initiative to attack now, it would be more difficult to find the opportunity later.

Su Chen never expected that Yinbao would attack at the moment when he was distracted. Fortunately, the girl with rich combat experience remained vigilant from beginning to end, and released her right index finger the moment Yinbao knocked open the glass door.

Whoosh!

Accompanied by a low-pitched scream, the Hidden Leopard that smashed open the glass door was slowed down, unable to dodge the oncoming sharp arrows.

The arrow was extremely sharp and easily penetrated the hidden leopard's front right limb. As blood spattered, the hidden leopard screamed and had to ventilate again. Its ugly appearance was exposed to Su Chen's field of vision.

Compared with the fragile and mysterious blood rat, the hidden leopard's pain-taking ability and fighting spirit were obviously much stronger. It endured the severe pain and rushed towards Su Chen, hoping to bite off Su Chen's neck.

Su Chen is afraid of unknown and strange creatures, but facing the injured Hidden Leopard with a single attack method, he is full of confidence.

Su Chen took the initiative to take a step forward, and struck the hidden leopard that jumped into the air with a heavy blow with the sharp blade in his hand.

Just when Su Chen was about to succeed, the hidden leopard's long tail covered with spikes suddenly swung towards Su Chen's right waist.

Su Chen had no intention of trading with it to the extreme. He held his breath and retreated, quickly distancing himself from the hidden leopard.

Su Chen reacted quickly, but his body's abilities were limited, and he had no time to dodge the Hidden Leopard's heavy blow and tail flick.

Just when Su Chen was about to use the Qiankun inner armor to resist, the girl shot a second sharp arrow in the gap.

The sharp arrow that was supposed to hit Hidden Leopard's right eye socket hit its tail. Hidden Leopard was in pain and flicked its tail wildly, allowing Su Chen, who was unable to avoid it, to barely avoid the heavy blow that would have hit it.
