After Jiang Lan saw his father knocking on the door of Su Xiaoqing's four people, he comforted them: "Don't be afraid, there are zombies outside who can only climb the wall." He opened the window and sent a spike of earth to pierce the zombie who was excited to "see" someone. At this point, it was discovered that this zombie has the same characteristics as ordinary zombies - it will not avoid attacks.

Killing this zombie, Father Jiang quickly stretched out his hand and grabbed the zombie's corpse, and dug out the crystal nucleus of the zombie with the help of Su Xiaoqing. At first glance, this crystal nucleus marble is the size of a translucent light green marble, which looks like a translucent green marble, but the faint green light it emits makes people see at a glance that it is different from marbles.

Jiang Lan also came out of the space, ran upstairs quickly and lightly, entered the room of Su Xiaoqing and the four of them, curiously took the light green translucent crystal nucleus from Jiang's father's hand, closed his eyes and felt the spiritual power inside, and found that this crystal nucleus was twice as high as the spiritual power of the ordinary first-level crystal nucleus, and it was much purer.

"The spiritual power in this is twice as high as the first-level crystal nucleus, and it is purer, and there are fewer impurities, Dad, do you think this will be the second-level crystal nucleus?"

"Maybe. Xiaolan, you can keep it. Dad Jiang said casually.

Jiang Lan nodded and put this crystal nucleus into her waist bag, because there was only one, she didn't plan to put it into the spiritual spring.

"Dad, go get some sleep, I'll keep vigil."

Father Jiang knew that Jiang Lan could use cultivation instead of sleeping, and it didn't matter if she didn't sleep, and she also had the five essences by her side to help, so he nodded: "Then I'll go to sleep, Xiaoqing Xiaoxi Xiaojun Xiaobao, you guys go to sleep too, we have to hurry tomorrow." ”

Dad Jiang patted everyone's head and left.

Jiang Lan felt a little uncomfortable when she saw her father caring so much for the four boys, after all, her father wanted a son more, and if her mother could still give birth, she didn't mind having another brother.

Jiang Lan smiled and said to Su Xiaoqing: "Everyone's performance today is very good, the boss is very satisfied, Xiaoqing go wash your hands, and then everyone go to sleep." "The rare four children are very well-behaved and sensible, Jiang Lan loves them very much, speaks softly to them, and is very kind. Therefore, they are not like some pampered children, who are willful and difficult to discipline.

Jiang Lan returned to his room, sat on the bed and called out the water spirits, fire spirits, gold spirits and earth spirits in the space, and said, "Xiao Shui, Xiao Huo, Xiao Tu, Xiao Jin, please help my sister clean up the zombie group outside, my sister should hurry up and practice spells." But be careful not to show your figure, maybe Sputnik will take pictures. Although the five spirits can't leave Jiang Lan at a distance of more than five hundred meters, they are not restricted within five hundred meters, even if Jiang Lan sits still, they can help her clean up the zombies around about five hundred meters, Jiang Lan didn't call Mu Jing, because at this time Mu Jing is developing some new drugs for him, Jiang Lan is looking forward to the effect of the new medicine he developed, and she can use one more medicine when the time comes.

The four little ones took the order and left, and Jiang Lan began to practice the purification technique. This purification technique Jiang Lan had deliberately left one or two zombies to test its lethality to zombies when he hunted the crystal nucleus during the day, and found that its melting power on zombies was very strong, as long as the decaying zombie parts touched the light ball emitted by the purification technique, it would turn into a black gas and dissipate without a trace, but the five essences told Jiang Lan that this purification technique did not harm the human body, but could achieve the effect of purifying the zombie virus, listening to the characteristics of these purification techniques, Jiang Lan felt that this was similar to Xiaobao's ball of light, The difference is that she can continue to emit much more light balls than Xiaobao's, and the volume of the light balls is also much larger, which is more lethal to zombies and purifying to zombie viruses.

After practicing the purification technique for a while, Jiang Lan learned the fireball technique, the water polo technique, the ice arrow technique, the earth thorn technique, the winding technique, the handling technique, the wall piercing technique, the stealth technique, and the air fetching technique, Jiang Lan felt that these spells were very simple to learn according to the laws of spells and true qi operation, but the failure rate when using them was very high, and they could not be mastered at once. It's like babies learn to stand and walk, it's not difficult for them to stand up and take a few steps, but it's not easy to stand longer and walk farther, you have to wait until your body is strong and grown, and you have to repeat countless falls, get up, and practice with perseverance to stand and walk for a long time.

Now Jiang Lan's spells are like a baby who is learning to stand, and the chance that she can successfully use spells is only one in ten, which is very difficult to use, and because she is not proficient, she will waste a lot of true qi when she uses spells. Despite this, Jiang Lan happily continued to practice the Purification Technique. She knows the truth that she can't chew too much, so many spells she can't cultivate at the same time, only one comes, one by one, and master one or several of them first, in order to achieve the purpose of rapidly increasing her strength. She decided to prioritize stealth, followed by Water Polo, Telekinesis, Wall Piercing, Handling, Fireball, Ice Archery, Earth Thorn, and Winding.

Stealth technique Jiang Lan practiced against the dressing environment of the room, at first she could only be invisible for two or three seconds, and nine times out of ten spells failed, but slowly she succeeded once twice, and the stealth time also increased from two or three seconds to tens of seconds, one minute, and a few minutes, until she could be invisible for fifteen minutes, the four little guys came back after completing the task, and Jiang Lan, who had accurately found the stealth state, handed over the first-level crystal nuclei they had harvested to Jiang Lan, four piles of first-level crystal nuclei, adding up to more than two thousand, The four piles of crystal nuclei were all cleaned, and Jiang Lan directly put them into the Lingquan Lake in the space and soaked them.

Jiang Lan raised his hand and looked at his watch, it was already three o'clock in the morning, so he asked strangely, "Why have you been there for so long?" Killing 2,000 zombies doesn't take you two hours, right? There was no reproach in his tone, just pure curiosity, the four little guys were all in the origin state, so Jiang Lan couldn't guess from their behavior and demeanor.

The four little guys said a few words in a few words, and Jiang Lan understood, after they killed the zombies and destroyed the corpses. And because of playfulness, I frolicked outside for a while.

Although Jiang Lan couldn't think of anything fun about the four little guys in the middle of the night, and he couldn't leave her for 500 meters, but the child's heart is the most elusive, and sometimes the things that adults find boring and boring can just make the child feel very interesting, so Jiang Lan didn't ask too much, put them into the space and continued to practice his stealth skills.

Jiang Lan didn't know what the specific principle of this stealth technique was, but she knew that keeping her true qi relatively stable and sufficient during the stealth state was a necessary condition for maintaining the stealth state, so once she used the spell or the true qi was insufficient when she was in the stealth state, she would get out of the stealth state, but the actions that did not use her true qi such as talking and running would not affect the stealth state.
