When Zhang Heng saw Hao Qi the next day, Hao Qi stood in a daze at the agreed place. When Zhang Heng walked closer to him, Hao Qi came to his senses.

"What's wrong? Did you find something wrong?" Zhang Heng hurriedly looked around.

Hao Qi shook his head and said, "No, it's my concern... Let's go, go buy things, let's talk while walking."

After Zhang Heng nodded and affirmed, the two of them headed towards the market. Halfway through, Hao Qi suddenly asked: "Zhang Heng, if we found evidence, have you ever thought about how to rely on evidence to clear your father's grievance?"

Zhang Heng was stunned for a moment, and after a long time, he shook his head and said, "I haven't thought about such a faraway place. Let's not talk about whether we can find evidence. Even if we have found evidence, to be honest, I really don't know how to clear my father's grievances. After all, the enemy I have to face is not just one or two people. Maybe only Xide is on the surface, but in fact, this is what the entire Baicao Kingdom did... I don't know, even if we have evidence at that time, prove that red blue grass can be planted, and the country can also say it black in white, so..."

"Is that... I understand." Hao Qi said this in a low voice, and then he didn't mention anything again. He just asked Zhang Heng what supplies to buy next. The two discussed and finally bought two large bags of supplies, enough for the two to survive outside for more than two months.

Then the two of them did not set off immediately, but went to the library first, sorted out the things they had investigated these days, and searched for some geography books, historical documents and other records of Baicao Kingdom. Then the two people set off in the afternoon and left the capital of Baicao Kingdom.

Without saying a word, the two of them returned to the small village without any danger, and then continued to start a new round of investigation.

That's it, another month passed.

In this month, the two of them re-examined the remaining areas where there may be blind spots, but unfortunately, they still found no traces of possible existence, and there was no other discovery. Things were in a dead end, and there was no possible breakthrough. Just as countless people had investigated after Zhang Heng's father "deathed" and countless people had found no treasure land that could plant red blue grass.

To be honest, when things got to this point, Zhang Heng had already begun to despair, because from any situation, even though his father had not stole Sid's research notes, his father probably lied, and there was no possibility of planting red blue grass, because there was no such treasure land in the places where his father might have been, and his father... perhaps not so innocent...

On this day, the two of them emerged from a cave in a luminous crystal passage and then climbed along the mountain road and arrived at the range above the snow line on the top of the mountain. When they got here, Zhang Heng suddenly stopped moving forward, but sat next to the cliff, staring blankly at the distant world.

Hao Qi looked at Zhang Heng silently for a long time before sighing, sat next to Zhang Heng, and at the same time pulled out a cigarette to light it, and said while smoking: "What? Are you desperate?"

"There is a little bit..." Zhang Heng did not shy away, but said in a low voice: "We have been to all the places we should find, to find, and to walk. Almost all the traces my father can go. You must know that when we cover the range, it is the fastest distance in a straight line. This must be more than the distance my father can go to, but we have searched all the places we can find, and we can no longer find any reason to say that my father is innocent. I... indeed began to despair."

Hao Qi did not blame Zhang Heng for anything, but just smoked silently. After waiting for a long time, he suddenly said: "I have played a game before, and there is a character's words that I like..."

"Is the game? Character's words? Is it a tabletop game? Recently, a game called Wanwan Card has been passed from the Haitian Kingdom." Zhang Heng said strangely.

"Don't care about those details!" Hao Qi replied angrily, and he continued: "There is a sentence for this character... Let me try again when I just fell. This sentence, in the ten years of practicing boxing alone, in the days when I can't see the hope for the future, when I stood facing death, this sentence flashed in my mind. Now I tell you, I hope you can encourage me."

Zhang Heng did not look at the so-called characters in the game again. He just murmured this sentence silently, asking me to try again when I just fell, asking me to try again when I just fell, and asking me to try again when I just fell... After repeating this, Zhang Heng's eyes finally slowly became more and more energetic. He finally stood up and was about to look at Hao Qi with a smile, suddenly his feet slipped and he fell down the cliff.

But how fast Hao Qi's reaction was? Almost as Zhang Heng turned over toward the cliff, he had already stretched out his palm. When Zhang Heng's body had just fallen about one meter away, he had already lifted Zhang Heng's arm, and said with a smile: "Do you want this? Do you think you can really encounter a secret realm when you fall off the cliff like in those novels? Then you get the treasure and the secret book?"

Although Zhang Heng was startled, he laughed and said, "We have investigated the mountain path below the cliff more than once. What secret realm is there? But it's a good thing that you are there, otherwise I'm really dead."

Hao Qi smiled and lifted Zhang Heng up. After Zhang Heng got up to the cliff, his other hand shook, an ordinary blue grass with light blue leaves mixed in green, and a standard ordinary blue grass herb.

"There are blue grass growing on the cliff. My father must have been looking for herbs everywhere on these dangerous cliffs..."

Zhang Heng was still standing on the edge of the cliff. He threw the blue grass away and said, "Don't worry, Hao Qi, I will never give up until the end. Let's go to the place where we fell again. Father, I will definitely... Wait, wait, Hao Qi, I seem to have thought of something!!"

Hao Qi was stunned for a moment, and he didn't come back to his senses for a while, and Zhang Heng said anxiously: "I just have a thought, but I haven't thought it through clearly yet. Please wait for me to think about it..."

Zhang Heng immediately walked back and forth on the surrounding flat ground, and his walking speed was getting faster and faster, and his pace became more and more urgent. At the end, he suddenly looked at Hao Qi and said, "Hao Qi! Please answer me seriously. Really, please, I'm fine to answer me seriously. Is it okay?"

Hao Qi was silent for a moment and said to Zhang Heng seriously: "Yes, I will answer your next sentence seriously, and will answer you with the answer in my heart, using this world as a proof."

Zhang Heng took a deep breath and looked at Hao Qi with a pleading look and said, "So, Hao Qi... can I trust you? Just like my brother who trusts me, I will entrust my life to you. Can I trust you?"

Hao Qi did not answer the first time, but looked up and thought silently, then solemnly replied: "Yes, as long as you have not done something that makes you ashamed and guilty as you are now, then you can trust me, just like your brother who trusts you, entrusting your life to me, and I will never let you down."

Zhang Heng took a deep breath again and exhaled deeply again. After a long time, he said firmly: "Then, Hao Qi... I think I have found a way to plant red blue grass, just like the method my father found at the beginning. This may be the only way to plant red blue grass in Baicao Country!"

"Hmm? What's the solution!?" Hao Qi asked immediately.

Zhang Heng did not express any objection, but he still said: "Although I am sure I found it, I still have to do some experiments first. Hao Qi helped me pick bluegrass, a large amount of bluegrass, pick them all the way. It's late today, and we will start the experiment tomorrow!"

Then along the way, the two began to pick bluegrass, and Zhang Heng also told Hao Qi without hesitation about the principle of planting red bluegrass. Of course, these are just his personal inferences. Whether it is really feasible or not needs to be verified.

First, Zhang Heng proposed the precautions they discussed at the beginning, that is, the difference between Zhang Heng's father and other search personnel. In fact, it is very simple to summarize. One is that Zhang Heng's father has been walking here for decades. He did not only search here a few times, but lived here.

Second, because Zhang Heng's father died, he brought herbs back every time he came back, and even a large part of his energy was spent digging herbs, so he had to carry herbs for a long time.

“… Based on the above two differences, my guess is like this.”

Zhang Heng said to Hao Qi as he walked: "First of all, my father picks a lot of herbs every day, and these herbs are placed on him. At the same time, he also wants to find medium and large prey that may appear, so he will run around everywhere, not as if there were any treasure land as we expected at the beginning. In fact, we all overlooked a very important fact. What my father said at the beginning was planting, that is, it is a method that can be mass-produced anywhere, rather than a miracle produced by specific treasure lands of heaven and earth. Our thinking was deviated. Because it is treasure lands, we took it for granted to bring the red blue grass into a situation where treasure lands can be produced, without understanding the literal meaning of this sentence. Planting can be produced anywhere and at any time like crops."

Hao Qi became more and more surprised as he heard it. He couldn't help asking, "Then what? How can we do this?"

"Let me say it slowly." Zhang Heng picked a bluegrass under the shadow of a tree. He continued: "First of all, my father carried a lot of herbs on his body, and picked fresh herbs. He searched for prey everywhere in the authentic mountain tunnels. Day by day, year by year, the herbs he carried and the seeds of herbs also scattered in the authentic mountain tunnels along his footsteps. Day by day, year by year, most of the herbs withered and died because they came to places that were not suitable for growth, but some of the herbs survived. Then one day, when my father walked the old path he had walked for decades, he was shocked to discover a fact... In a certain place, hundreds of bluegrass grew in acre of land, and all the bluegrass survived. At the same time, a red bluegrass appeared among the bluegrass."

Speaking of this, Zhang Heng suddenly stretched out a fist and said to Hao Qi: "Hao Qi, how do you think I am? How good is my physical fitness?"

Hao Qi looked at Zhang Heng seriously and said for a long time: "You are not very strong. This is the truth. I guess you will spend most of your time on books and on those treasures of treasures. Your strength can be said to be very weak, but your physical fitness is, I personally estimate that it will be one year later and half a year later, and you will probably be able to reach the level of quasi-internal strength."

"That's right."

Zhang Heng withdrew his fist and squeezed it tightly. He then said: "In theory, it is impossible to achieve the current physical fitness based on my number of times and efforts in practicing martial arts. Practicing martial arts is a process of retreating if you don't advance. My physical fitness shouldn't be at this level. I used to think that I might be gifted and born with physical fitness, but if I think about it carefully, even if it is an innate Taoist body like you, before you achieve the internal energy realm, your physical fitness will not be like me now. Before you achieve the internal energy realm, your physical fitness has not exceeded your martial arts level, and you can directly achieve the quasi-internal energy realm, right?"

Hao Qi didn't know how to answer for a moment. After all, he was not a real innate Taoist body, so he was silent. Zhang Heng thought he had made a promise, so he continued: "So I have a reason. My father had already obtained a red blue grass back then, and he gave me this red blue grass. It's just that I was young and didn't know. Relying on the effects of this treasure, my physical fitness base was much stronger than that of ordinary people, which led to my current situation..."

"Did you know? Hao Qi, the leaves of bluegrass are blue, and although there is also green chlorophyll, most of the nutrients of bluegrass do not come from photosynthesis. Photosynthesis is just a supplement to its nutritional source. Bluegrass only needs a small amount of light to survive. What is more needed is a large amount of water and a large amount of soil, so bluegrass grow better in dark places. And you should know that under the ground, there are dark lights in many places. Whether it is plants or minerals, just such light is enough to meet the needs of bluegrass for light..."

"You can imagine it? In some passages below the ground, or those narrow dead-end alleys, there is only one direction, there is no soil in one direction, there is soil above, there is soil below, there is soil in three directions, and there is even soil on pillars protruding from the wall. In such an environment, as long as there are luminous ores, bluegrass can survive in such an environment, and..."

Zhang Heng spread out a blue grass on his hand and roared loudly.

"One acre of land can survive more than a hundred bluegrass plants!"
