Fang Hanxiao has tried at least 10,000 schemes and designed more than 10,000 symbols, but so far he has not found any of them that is suitable.

In the end, he remembered to replace it with the Chinese character "heart", which is also a kind of symbol.

Unfortunately, it still doesn't work.

There is a purpose, but the right symbol cannot be found to replace it......

Han Xiao remembered to use algebra to solve the problem again, which was actually a method, but algebra really couldn't solve the problem of runes.

Han Xiao, who really had no choice, had to set up the rune array first and try them one by one......

"When rigorous science is a game for me...... Hmm?" When Han Xiao used the word "heart" in the oldest hieroglyphic script as a rune, the fit of the rune array was the highest - that is, although it was not the most suitable plan, but his fit was the highest, then it means that if you improve it in this direction, it is possible to calculate the best plan.

In the end, Han Xiao found out what the problem was.

The reason why the previous heart talisman was imperfect was because Han Xiao only focused on the illusory and intelligent side of the heart, and did not notice that the heart actually had a real side.

The heart, first of all, is a blood pump, and it is like an engine in the human body. Without this "engine", the qi and blood of the whole body would not be able to function normally, and secondly, it is a perceptron' officer with intuitive thinking ability......

After combining the virtual and real aspects of the heart, the perfect form of the heart character was finally determined by Han Xiao.

The birth of the Heart Talisman was the second rune created by Han Xiao after the Qi Talisman.

Anyone who has studied runes knows that there have been many amazing people who have created many new runes, but in the end, those runes have not stood the test of time.

In the end, all the people who learned the talisman used and recognized only the five symbols of heaven and earth, that is, the five symbols of earth, water, fire, wind, and air.

These five symbols have the wonderful use of communicating the heavens, the earth and the universe.

Han Xiao's Qi Talisman and Heart Talisman were invented for people, and they had no utilitarian heart, just a need. He needed to use such runes, which is why he thought of inventing them. Things are invented to be used, not to be shown off.

As soon as the heart talisman came out, Han Xiao was very happy, but he didn't be happy for long, and immediately put the newly determined heart talisman into the talisman array to use. He was going to transform his rune array, which was another interesting and complicated thing.

This busy, Han Xiao seemed to have no concept of time......

Anyway, by the time he came out of the "retreat" state and was about to go to the battlefield for a bloody shame, many Spirit Sword Sect disciples had already come down from the battlefield.

It is said that this confrontation between the Spirit Sword Sect and the Valley of Ten Thousand Demons is nearing its end.

After understanding, Han Xiao knew that every conflict between the two major forces would have a beginning, a high tide, and an end, and over the years, a tacit understanding had almost been formed.

That, of course, is the general trend towards a full-scale fierce confrontation.

As for the conflict between the two major forces, it has not stopped for a moment.

I'll sneak up on you today, and you'll hit me tomorrow, that's normal.

finally prepared well, but ushered in the end of this all-out war, Han Xiao was a little depressed.

However, isn't the war still going on now, then there is still a chance to show the skills of an assassin and reap the benefits on the battlefield.

Han Xiao now, there are several more talisman arrays in his body.

For example, the Invisibility Array......

This is much more powerful than a simple invisibility talisman, and after activation, the divine sense can't detect it.

As for whether Jian Zun's sword heart can be detected, Han Xiao doesn't know, because he hasn't tried it.

Now, his Void Rune Array and Stealth Rune Array have all been integrated into the Qi Rune and the Heart Rune, two runes created by him. The divine sense of ordinary masters cannot be detected, so Han Xiao really wants to go to the battlefield to try his skills.

Han Xiao took his war beast and all his subordinates, quietly left the Tiangong Academy, and sneaked into the battlefield in a low-key manner.

The Invisibility Array activated......

And Han Xiao's Void Rune Array and Spirit Gathering Combination Rune Array were running all the time.

He also deliberately walked over to a group of Spirit Sword Sect cultivators in the Jindan stage and felt their reactions—they didn't even notice Han Xiao's existence!

Han Xiao smiled slightly, this proved that his talisman array was still useful.

However, he was not too careless, and continued to sneak in a low-key manner......

When he sneaked into the middle of the demon clan, he found that those demons didn't notice his existence at all, but only nervously watched the Spirit Sword Sect monks in the distance, and for Han Xiao, who was not far from them, they seemed to treat him as air.

In the distance, a group of Spirit Sword Sect cultivators also stared at this group of wolf demons, and the number of both sides was about the same, and they all slowly approached, planning to fight it out......

Suddenly, a small sword formation composed of thousands of flying swords appeared out of thin air in the demon clan, brushing the ground, and within a second, hundreds of Jindan-level wolf demons were wiped out.

Immediately afterwards, the demon bodies of hundreds of wolf demons were put away......

The remaining group of Spirit Sword Sect cultivators were stunned as they looked at the place that was already empty, and only a place of wolf blood remained.

"Sword Formation...... Is it Zhao Tianxing, or is it Han Xiao?"

"With such a fast speed, it should be Han Xiao'......"

"But we don't even see him, is he far from here?"

Han Xiao's move can be regarded as robbing their monsters, but even if Han Xiao doesn't rob them, they will be evenly matched with the hundreds of wolf demons, and they won't have much advantage.

In an instant, there are really not many people who can kill hundreds of Jindan-level wolf demons.

Among the Jindan-level cultivators, the only people who could have this ability and were proficient in the sword formation were Han Xiao and Zhao Tianxing.

Han Xiao accepted the hundreds of wolf demons, and muttered to himself in his heart: "People can be invisible, but once they make a move, the sword can't be hidden." ”

The reason why he unexpectedly destroyed the wolf demon's team as soon as he made a move was to grab time, and secondly, because as soon as the sword came out, his whereabouts would definitely be exposed, so he would get a little more benefits, and then transfer immediately.

If he made a move once, Han Xiao would not make another move in this area.

He wandered between the battlefields, although he didn't make a move, but when there was a demon body on the battlefield, or after the death of a monk, the magic weapon and storage bag were left behind, Han Xiao would unceremoniously snatch it into his space storage bag.

He picked up a lot of demon bodies, demon heads, and demon legs of the demon clan, and Han Xiao also picked up dozens of space storage bags for the monks of the Spirit Sword Sect who were killed by the demon clan.

After a long time, he suddenly discovered that picking up "salted fish" on the battlefield is actually a way to make money.

It's just that Han Xiao can't be a professional salted fish snatcher, his role this time is a battlefield assassin, with the goal of assassinating demons.
