The next day, Xu Lin still got up early, and saw that the door of the prince's room was still closed, and it seemed that the prince had not gotten up yet.

Xu Lin shook his head with a smile, he swore to do a big job yesterday, but now he is still sleeping.

went downstairs to eat something, and Xu Lin took Xiao Hei to the trap to clean up the prey.

Today's luck seems to be good, there are seven zombies lying on the seven trap arrays, it took some time to dispose of these prey, absorbing seven energy crystal nuclei, Xu Lin has accumulated just 11 units of energy at present.

Back in his room, Xu Lin opened the silver creation ball.

Although Xu Lin had been mentally prepared early, when the empty light curtain appeared in front of Xu Lin's eyes, Xu Lin's mood was still much lower.

"Damn, how the hell can you create something new! You don't need 100 units of energy! What's the use of me holding this broken mark! After a few days of anticipation in exchange for this result, Xu Lin was also a little angry and smashed his fist on the wall.

The feeling that I have the incredible Creator Mark of the Ten Thousand Worlds, but I don't know how to use it, is really maddening.

"This thing is not earthly, and I may never even know how to properly cultivate the seal! Then how can I get revenge! Thinking of this, Xu Lin held his head in his hands and sat on the edge of the bed.

In fact, every time Xu Lin collects energy, he will check the creation ball, but 10 energy is already Xu Lin's psychological bottom line, after all, it only took 1 unit of energy to create Xiao Hei, but now, there are still no new items to create the creation ball, Xu Lin feels unprecedentedly confused.

Xu Lin was silent for a moment before raising his head again. "No, I'm not going to give up!"

"Calm down, Xu Lin, the Ten Thousand Worlds Creator Mark can create Xiao Hei, which means that it is useful, maybe it is because it is powerful, so it is difficult to get started." Xu Lin comforted himself.

"Since there are no new items, at least you can upgrade Blackie now." Xu Lin looked at Xiao Hei who was sitting obediently beside him. "This is an upgrade, not an evolution, so Xiao Hei should still be a dog after upgrading, even if his sense of smell is not as good as that of a Labrador, it's a big deal to be more careful when he acts in the future. What's more, upgrading may also enhance Blackie's abilities. ”

Xu Lin finally decided to give up continuing to accumulate energy for the time being, and upgrade Xiao Hei first.

It only takes 1 unit of energy to upgrade Xiao Hei, and Xu Lin has long been enough, "Xiao Hei, are you ready?" ”

"Wangwang." Blackie stood up and wagged his tail excitedly.

"Yes." Xu Lin looked at Xiao Hei tightly, he didn't know what changes the upgrade would bring.

Taking a deep breath, Xu Lin summoned the yellow upgrade orb.

Opening the "Unit Upgrade" sub-menu, Xu Lin no longer hesitated, and gave the order of "Upgrade Labrador Recovery Dog" in his mind.

But what Xu Lin didn't expect was that it was not Xiao Hei who changed first, but himself.

"This, this feeling of exhaustion, is stronger than last time!"

Last time, Xu Lin's mental state was very poor, but this time Xu Lin had a good rest recently, even so, Xu Lin immediately felt that this feeling of exhaustion made him almost unbearable.

At the beginning, Xu Lin felt that his spirit couldn't even concentrate on one point, and the whole person became in a trance, and his eyelids were so heavy that he couldn't support it. And the fatigue is getting stronger and stronger, and it seems that it is continuing to grow, and if this continues, he will not last long before he will fall asleep.

Xu Lin forcibly gathered a bit of energy, and glanced at Xiao Hei in front of him, who was falling to the ground and convulsing.

"Blackie!"

The first thought in Xu Lin's mind was that if he couldn't complete the upgrade, Xiao Hei would probably never be able to stand up again!

During this time, Xu Lin has not only regarded Xiao Hei as a pet dog.

It helps Xu Lin find supplies, avoid zombies, when he works, he always accompanies Xu Lin, when Xu Lin is depressed, he always leans on Xu Lin's legs, it comforts Xu Lin in this way, every time Xu Lin wakes up every night, Xiao Hei always wakes up as soon as possible.

It can only have a simple exchange of thoughts with Xu Lin, but it has always been by Xu Lin's side.

It is Xu Lin's family.

"Nope! Blackie! Xu Lin will never leave Xiao Hei behind, he has cheered up several times, but the feeling of exhaustion is not a pain, it can be forcibly endured, the more this feeling of exhaustion struggles to resist, the more serious the situation is.

After several struggles, Xu Lin even bit his lip to no avail, and finally, Xu Lin fell headlong to the ground.

The moment the "little black ......" was planted to the ground, a tear slipped from the corner of Xu Lin's eyes, and he shouted the last time, and his thoughts could not be concentrated.

With a pop, Xu Lin was like a drowning man at the moment he fell to the ground, trying to catch something, but he just swept some weightless debris on the bedside table to the ground.

On the other side, Xiao Hei's eyes also slowly closed, and the vitality on his face became weaker and fainter, it seemed that Xu Lin's guess was likely to be true.

Among the piles of miscellaneous items scattered around Xu Lin, a small wooden box was broken and opened by itself, and a strangely shaped wooden block inside fell out of the box, which was exuding a refreshing faint fragrance at this time.

This is exactly the best agarwood that Xu Lin found before.

In addition to agarwood is a luxury, it is a precious Chinese herbal medicine, refreshing and clearing the brain, calming the nerves, at the same time, Buddhism and agarwood also have a deep origin, agarwood has always been known as the precious Buddha tool of Buddhism, is to drive away evil spirits, avoid disasters and protect the holy product.

It can be seen that agarwood itself also has a very magical effect.

A faint fragrance came, and Xu Lin, who had already been unconscious, frowned slightly, and gradually regained a little consciousness.

Xu Lin felt that with his breathing, the feeling of exhaustion was not as strong as just now, so he instinctively began to breathe greedily into the fragrance of agarwood.

With the help of agarwood, Xu Lin could barely resist the strong feeling of tiredness, and he struggled to sit up cross-legged.

At this time, Xu Lin didn't dare to have distracting thoughts, and kept his breathing steadily, for fear that this feeling would disappear at any time.

I don't know how long it took, Xu Lin kept this state, fighting against the tiredness in his brain, and finally, he heard Xiao Hei next to him move.

"Wangwang." It wasn't until Xiao Hei's voice came that Xu Lin finally breathed a sigh of relief in his heart.

"It's finished?" Xu Lin barely opened his eyes, and Xiao Hei in front of him was standing in front of him, wagging his tail happily, looking energetic, where was the guy who fell to the ground half-dead before.

The boulder in his heart fell to the ground, Xu Lin couldn't hold on anymore, and fell directly to the ground and fell asleep.

The curtains could no longer cover the sunlight outside the window, Chu Jun rubbed his sleepy eyes, stretched his waist, and looked at the time, it was half past eight in the morning, "I have a lot of work to do today, I have to get up early." ”

Usually she doesn't get up until nine o'clock, but the memory of the wall that can be built soon, the prince is still very excited, she got up with a grunt, washed her face in the bathroom on the second floor with the water she washed yesterday, and poured a small glass of water to brush her teeth.

"It's all hard work, and you don't have the strength to do it without breakfast." Chu Jun muttered while combing his hair, "Annoying Xu Lin, if you have to take the warehouse key, I have to go to him for breakfast." Don't get up so late, pig! ”

After cleaning up, Chu Jun ran to Xu Lin's room, when Xu Lin came back before, the door was not locked, and as soon as Chu Jun pushed it, the door opened.

As soon as he opened the door, the prince first saw Xiao Hei standing at the door, "Damn!" Xiao Hei, I haven't seen you for a night, why do I think you've grown a little taller! The prince looked at Xiao Hei carefully, "It's really tall, are you Xiao Hei?" ”

"Hey, Xu Lin, what's going on?" The prince wanted to ask Xu Lin about the situation, but saw Xu Lin fall to the ground, "I'm so old, I'm not honest when I sleep, and I can still fall out of bed?" ”

The prince was already completely messed up by the scene in front of him.
