After several months of ** attack, the results received at first were quite fruitful, but after Wu Zong suddenly ordered all the troops stationed abroad to retreat to the city where they were located, the effect of the ** attack launched by the ** army was greatly reduced, because the Tianwu Sect corps and its servant forces that retreated to the city were protected by the city protection array, and the ** troops of the Northern Regions were intercepted by the city protection array.

There were several elders of the Tianwu Sect when they found out that ** was coming, and they wanted to take a closer look, what kind of magic weapon was this thing that made them suffer a big loss and the speed was like a meteor, but when they approached these **, these elders of the Tianwu Sect were suddenly detonated ** and exploded into ashes, after this lesson, the Tianwu Sect strictly ordered the disciples of the sect not to approach this strange thing.

Zhao Yuanchun knew that the launched ** was difficult to form an effective lethality against the enemy, and he was irritable.

Han Zi looked at Zhao Yuanchun, who was extremely irritable, she was also very entangled, with the current function of the earth, it was obviously impossible to break through the impregnable city protection array, not to mention that there was also the monk divine consciousness like the radar on the earth, it was difficult to launch a surprise attack without the enemy being caught off guard.

When Han Zi was thinking about it seriously, Zhao Yuanchun, who was originally irritable, suddenly opened his mouth and complained: "Zi'er, if only our ** could avoid the miscellaneous divine consciousness of the Heavenly Martial Sect." ”

After Zhao Yuanchun finished speaking, he sighed and said: "Alas, it's a pity, this is just a fool's dream." ”

"I can't let the divine consciousness find out. Han Zi muttered quietly.

"What a word to wake up the dreamer!"

After listening to Zhao Yuanchun's whining words, Han Zi's face suddenly turned happy.

Zhao Yuanchun saw the joy on Han Zi's face, and thought to himself: "Is it difficult that Zi'er has found a solution?"

When Han Zi saw Zhao Yuanchun's eyes looking over, he told him what he thought.

"Uncle, if we add the Hidden Spirit Paint to the surface of the ** coating, and seriously improve the tail fire path, will we be able to do what Uncle said, so that the divine consciousness of the monks below the Yuan Infant cannot be discovered, and the ** we emit." ”

After listening to Han Zi's narration, Zhao Yuanchun slapped his head with his right hand and shouted, "Yes, why didn't I think of it." ”

Han Zi looked at Zhao Yuanchun's serious expression, very speechless, I, the chief designer of **, was still confused at first.

But now that there is a solution, but when he goes up to find the materials for the Hidden Spirit Coating, Han Zi has confusion in his heart.

"Alas, what a difficulty, one after another. ”

Just when Han Zi was worried about how to solve the problem of the hidden spirit paint, Li Ying's voice came from outside the door: "Sister, why are you worried here?"

As soon as Li Ying walked into the hall, she saw Han Zi sitting on a chair, her hands in her hands, and her face was full of sorrow.

Han Zi smiled bitterly at Li Ying, she is under a lot of pressure now, okay.

"Xiao Ying'er, you came just in time, sit down. When Zhao Yuanchun saw Li Ying coming, he immediately beckoned her to sit down.

"Thank you, uncle. ”

Li Ying thanked Zhao Yuanchun and sat next to Han Zi.

Li Ying didn't bother her when she saw Han Zi's state like a mountain pressing on the top, but she thought in her heart: "What is it that makes her sister, who always surprises her, have so much pressure." ”

After a long while, Han Zi still didn't come up with a reason, shook his head with a wry smile and stood up.

Seeing Han Zi like this, Zhao Yuanchun couldn't bear to comfort him a little in his heart: "Zi'er, don't worry about this for a while, I believe there will be a solution, if it really doesn't work, we will think of other ways, and you don't have to be too careful about it." ”

Listening to Zhao Yuanchun's comforting words, Han Zi smiled and nodded, and said, "Uncle, please be relieved, I will definitely solve this matter." ”

Li Ying on the side listened to the conversation between the two, feeling a little in the clouds, what is going on with these two people, what is the matter, I don't understand, I really treat this person as air, right?

I saw Li Ying say in a very dissatisfied tone: "I said two, what kind of genius are you discussing, can you reveal a little bit to someone." ”

Han Zi and Zhao Yuanchun were a little embarrassed when they heard Li Ying's dissatisfied tone, and anyone who was left to hang aside would be unhappy.

Seeing that Zhao Yuanchun was a little embarrassed and said to Li Ying: "Ying'er, that's the case, your sister and I are discussing..." ”

Zhao Yuanchun said a lot of things, Li Ying could be regarded as understanding, only to see Li Ying's expression a little like looking at two teasers, looking at the two of them and saying casually: "What should I be, isn't it just a hidden spirit coating." ”

Oh no, my good girl, isn't it just a hidden spirit coating, this Nizi took the wrong medicine, one of the two of them is a super scientist, and the other is a great monk in the middle of the Yuan Infant, they didn't dare to say such a big thing, she is a little Nizi, she has such a big talk, she must have taken the wrong medicine, this is the same thought in the hearts of Han Zi and Zhao Yuanchun.

Looking at the fool-like look in the eyes of the two of them, Li Ying's heart instantly became angry.

Li Ying raised her head and said proudly to the two: "I said, don't believe it, I really have a way, do you want to hear it, two?"

Yo, it seems that maybe there is a way, Han Zi and the two nodded at the same time.

Seeing the two of them nodding at the same time, Li Ying said a little shyly: "I want to hear it, hehe... I don't want to talk about it yet, so let's talk about something else first. After Li Ying finished speaking, she pretended to be an unscrupulous girl, and happily watched the reaction of the two.

Han Zi and the others looked at Li Ying's evil smile, and they had the urge to beat people.

Li Ying was very relieved when she saw the emoticons that the two of them were forbearing.

"Hmph! After looking at you, do you dare to underestimate others, you really don't use bean buns as dry food. ”

Li Ying didn't sell Guan Zi either, and said with a serious attitude: "For my sister, the raw materials you said about making the Hidden Spirit Paint, I can look at the sixth-order Hidden Spirit Grass." ”

"Sixth-Order Hidden Spirit Grass, isn't that the material used to make the Hidden Spirit Rune?" Han Zi muttered.

"Hmm. ”

Seeing Li Ying nodding, Han Zi thought for a moment and said, "Since the Hidden Spirit Grass can make Hidden Spirit Runes, it should also be able to be used for Hidden Spirit Paint. ”

"Well, the sixth-order Hidden Spirit Grass is enough to isolate the divine sense detection of the monks in the late stage of the Jiedan, and Ying'er's method is very good. At this time, Zhao Yuanchun on the side also said.

Since even Zhao Yuanchun thought that the Hidden Spirit Grass was feasible and believed that it should be able to be used as a raw material for the Hidden Spirit Coating, Han Zi nodded and said seriously: "Since my uncle and sister both agree with the Hidden Spirit Grass, I have no objection, then ask my uncle to send people to collect a large number of Hidden Spirit Grass." ”

"Don't bother my uncle about this. At this time, Li Ying suddenly spoke.

Han Zi looked at Li Ying with some incomprehension after hearing this, Li Ying saw Han Zi looking at herself, she knew that she was a little reckless, she smiled at Li Ying sweetly and said, "Sister, that's the case, my brother and I found a lot of Hidden Spirit Grass on a deserted hill, from the first to the seventh order. ”

"Oh, I see. ”

Half a day later, Li Ying took Han Zi to the hill, looked at the hidden spirit grass that grew all over the mountain like weeds, and recited the space mantra in her heart to transplant all the hidden spirit grass all over the mountain to the medicine garden in the space, no matter what grade.

Li Ying was stunned and looked at the originally lush hills, and in a blink of an eye, it became a bald mountain.
