"Mom, I'm fine, I'm a little bit of a heat stroke."

Then in the dim light, Xie Lang found that his mother was much older than he had been a few years ago.

"Don't go to the construction site, your first priority is to study."

Xie Lang's mother, Huang Xiufang, carefully checked and saw that her son did not have any other external injuries, so she breathed a sigh of relief.

Xie Lang knew the situation at home and didn't want to be a burden to his mother, so he hurriedly said.

"No, Mom, I'll handle the tuition matter myself, you and Dad are still hiding at home to rest, and when I graduate from college and make money, we will also move into a big house in the city."

Huang Xiufang smiled with relief, her son has been very sensible since he was a child, and he has never been willing to be a burden on the family.

At the mention of his father, Xie Lang suddenly thought of something.

"Mom, is Dad asleep? I'm looking for him for something. ”

Huang Xiufang shook her head.

"Your dad is worried about you and hasn't slept all the time, you go in and tell him that he's safe."

As soon as he thought that the blood vial he had obtained from the system might heal his father's leg, Xie Lang felt extremely excited and walked into the back room, where Xie Aiguo was sitting leaning against the head of the bed with tears on his face.

Xie Lang knew that this was his father's worry about him, he had never seen his father cry, even when his legs were broken before, he knew that it was not his father who couldn't cry, he didn't want to cry in front of him.

"Dad, Mom, I recently heard about a new drug, and I heard that it can treat Dad's leg injury."

When Huang Xiufang heard this, her eyes lit up at first, but soon became dim again.

"Hey, we've spent a lot of money over the years, and now you're going to college......"

"No, it's good to lie in bed every day."

Lao Xie suddenly looked at Huang Xiufang, then at Xie Lang, and said suddenly.

Xie Lang only felt a sour nose, he knew that a large part of the reason why his parents didn't want to treat the disease was because he needed a lot of money to study.

"Dad, Mom, you don't have to worry about money, this drug has not officially entered clinical use, and now we are still calling volunteers for experiments, I see that the situation is quite similar to Dad's and I signed up."

Saying that, Xie Lang took out a vial filled with red liquid from his pocket, and before entering the door, he took out the blood vial from the system, but he didn't know if this thing had any effect on people other than himself.

Xie Aiguo and Huang Xiufang looked at Xie Lang with some suspicion, obviously this kind of pie-in-the-sky thing made them vigilant.

"Son, tell Dad, how much does this thing cost, Dad, this is an external injury, it must be bad to take medicine alone, don't be deceived."

"That's right, son, a lot of liars nowadays are picking on students like you."

Huang Xiufang also looked at Xie Lang with a worried expression.

Xie Lang smiled bitterly, he really didn't know how to say this kind of thing, after all, it was impossible for him to tell his parents that he had obtained a summoner system, and he bought this blood vial from the system shop.

"Dad, Mom, you just put 10,000 hearts, your son and I are not so stupid."

In the end, although Xie Aiguo and Huang Xiufang were suspicious, Xie Aiguo finally drank the medicine in the blood bottle.

Originally, Xie Lang was worried that it would not work for anyone other than him, but seeing that his father fell asleep peacefully after taking it, Xie Lang breathed a sigh of relief.

Since his legs were injured, Xie Lang's father had never slept peacefully, and listening to his father's snoring at this time, Xie Lang actually had a sense of security that he had not felt for a long time.

Ten minutes later, Xie Aiguo's snoring suddenly became smaller, Xie Lang was startled, and thought that his father had taken this medicine and had some side effects, so he hurriedly got closer, but found that his father's breathing was very stable.

He immediately understood that the medicine in this blood bottle is to improve people's health value, that is to say, this thing has an effect on improving the physical fitness of the entire human body, and this snoring is a symptom of a disease, and it seems that his blood bottle is beginning to work.

What made Xie Lang even more excited was that he found that his father's legs, which had some muscle atrophy due to no exercise all year round, actually bulged.

He hurriedly ripped open his father's trouser legs, but was surprised to find that his father's shriveled legs had begun to grow muscles.

"This ...... What's going on! ”

Huang Xiufang was so surprised that she couldn't close her mouth, this scene was simply amazing, you must know that she didn't have much hope, but she didn't expect that the medicine that her son brought back at this time was really successful.

After about five minutes, Xie Lang found that the medicine in the blood vial seemed to have no effect, and he hurriedly shook his father's shoulder.

But what he didn't expect was that his father sat up immediately as if he was frightened, and his fist smashed into Xie Lang's face.

Xie Lang was startled, he didn't expect his father to get up so angry, but fortunately, Xie Aiguo found that it was his son who immediately reined in his strength, and said with some doubts.

"Son, what are you doing, not sleeping in the middle of the night?"

"Lao Xie, you ......"

Huang Xiufang covered her mouth in surprise, how could this not surprise her, you must know that Lao Xie had to be helped if he wanted to get up before, but at this time, Xie Aiguo actually sat up by himself.

"Me?"

Xie Aiguo also reacted, looking at his wife and son with some excitement.

"Lao Xie, you get out of bed and take a look."

It was Huang Xiufang who reacted first, and hurried over to help Xie Aiguo get out of bed.

Xie Aiguo was too thin to prevent Huang Xiufang's help, only to see him turn over and get out of bed, but he stood up directly, but he was still a little unsteady when he walked, Xie Lang knew that this was because his father had been lying in bed for too long, and it would be good to get used to it again after a while.

Seeing his father stand up again, Xie Lang was extremely relieved, but at this moment, he clearly remembered the dinging sound in his mind, if he had put it before, he would have thought it was an auditory hallucination, but since he had the summoner system, he knew that it was the sound of the system's prompt.

Opening the interface, Xie Lang quickly noticed a flashing exclamation mark, there was nothing here before.

Under attack, the host sensitivity is tested to be 0.7, low-level, and the sensitivity is increased by the departure mission.

Xie Lang was stunned, not quite understanding what this meant, but at this moment, a figure suddenly flashed in his mind, Xie Lang only felt a chill all over his body, and couldn't help but shudder, an unprecedented sense of danger, as if a killing god had descended.

"Who is it?"

Xie Lang subconsciously became vigilant.

At this moment, a mysterious man wearing a hat and a cloak appeared in his mind, and Xie Lang immediately recognized it, this person was the character he immediately got to go out, the shadow of the blade, Tyrone.
