After Zhang Di finished calculating, he immediately had a plan, and in order to hurry up, he secretly spent some spirit stones, and entrusted the old man to a southbound caravan, so that they could take the old man to the southern Zhao country and settle down.

He himself took advantage of the hazy night to take the old donkey head of the demon corpse to the outside of Qingning City, and deliberately observed the traces of the power of the human spiritual energy cannon on the battlefield of the immortal and demon war that day.

I saw a straight river appear on the ground, about thirty zhang wide and three miles long, and a hill ran through a huge cave.

As soon as he saw such a scene, Zhang Di was stunned, and when he was neutral, tens of thousands of Heavenly Demon armies were rushing towards Qingning City in a dense manner, and when the human army was defeated, a white light suddenly flashed from Qingning City, and a thick pillar of light with a height of more than thirty zhang sprayed out, penetrating the Heavenly Demon Army, and the Heavenly Demon soldiers turned into steam wherever they passed.

And this pillar of light was not only powerful, but also pierced the opposite hill into a huge cave, and then disappeared into an unknown place.

Later, half a year passed, and several rains gradually filled this huge pit and became a straight river, as a witness to the battle between immortals and demons.

"It's so powerful! Is this the tremendous power of the psionic cannon? No wonder the Heavenly Demon Army is so jealous, if there is no psionic cannon and the city protection array, I'm afraid that the human city will not be able to hold it for a long time, right?" Zhang Di couldn't help but secretly exclaim, he heard the city lord proudly mention the psionic cannon when he visited the Qingning City Lord that day, which aroused his strong interest, so he wanted to come and see the ruins of the psionic cannon after it was used.

This look is really beyond imagination, it is really shocking!

But I was surprised. He also secretly pondered, figuring out the principle of this psionic cannon. It is estimated that some kind of formation was engraved on the artifact, and then a large number of spirit stones were instantly stimulated. Produced such a powerful pillar of light.

It is conceivable that the power of the psionic cannon is so great, and the spirit stones consumed must be a heavenly amount, and it is estimated that hundreds of thousands of spirit stones will have to be consumed at one time, right?

Thinking of this, Zhang Di couldn't help but secretly marvel, and became more interested in this psionic cannon, thinking that if he had the opportunity in the future, he would have to study the blueprints of the psionic cannon, which might be of great help to him to improve his strength.

The night was hazy. Zhang Di saw that some local human people, with incense, candles, and yellow paper, came to this big river to burn paper to worship, to comfort the dead family, but also to pray for the living family members, it seems that the people seem to regard this river as a symbol of the supreme power of human beings, with this big river seems to be able to defeat the heavenly demons.

Such a scene made Zhang Di chuckle in his heart, and suddenly thought of the monster that the young master of the Feihong clan had just secretly refined on Monday. As Zhang Di studied that drawing in the past six months and improved a lot of strength for the old donkey, Zhang Di also had a deeper understanding of the value of that drawing.

He knew that the drawing was only a tenth, if it was put together. The monsters that are refined will be extremely powerful, and I am afraid that they will not lose to the spiritual energy cannons mastered by humans, and they will even be even more powerful. Because psionic cannons are dead after all, and they can't move to fight. But the monster is alive and can move and fight.

Come to think of it. Zhang Di subconsciously touched the drawing in the storage bag, and said in his heart: "I am familiar with this thing anyway, so I should find an opportunity to give it to the master and ask him to present it to the sect, so as to attract the early attention of the sect, but for my own interests, I can't delay the major event of human beings defending against the heavenly demons!"

Glancing at the people who were kneeling beside the river and praying sincerely, he couldn't help but sigh: "If it is because of me that the conspiracy of the Heavenly Demons succeeds and harms these people, then I really have a disturbed conscience!"

In a trance, he seemed to see those people kneeling and praying turned into the figures of his parents and second uncle, and were praying for him in the capital of Zhao with their hands folded in the capital of Zhao not knowing how far away......

Immediately, his heart was sour, he sighed, and said to the old donkey head of the demon corpse: "Let's go, Master, let's go back to the mountain quickly!"

So the two of them no longer concealed their cultivation, and took advantage of the night to drive the light spirit technique, turning into two black shadows and heading towards Qingyue Mountain in Yueguo......

On the evening of the second day, Zhang Di came to Qingyue Mountain smoothly, and he did not go back to the mountain directly, but went straight to Zhongnan Gufang City, which was dozens of miles away to the south.

Before entering the market, he and the old donkey were dressed in disguise, and changed to the appearance of the previous yellow predecessors, wearing a gray shirt, burnt yellow skin, and two black beards;

Let the yellow spirit bird take a closer look, and indeed did not find the slightest flaw, so he asked the yellow spirit bird to be on guard outside the fang market, and Zhang Di took the old donkey's head and swaggered into the fang market.

When I came in, I couldn't help but be slightly surprised, I saw that people were coming and going in the market, it was very lively, and the disciples of various sects and sects were trading, and the expressions on everyone's faces were very eager, as if they were busy for something.

Zhang Di secretly wondered, stood aside and looked at it, pulled an irrelevant shopkeeper and asked: "Little Er, I left here to travel to the south for more than half a year before I came back, do you know why this place is so lively?"

That Xiao Er saw that Zhang Di played Huang Senior's appearance was extraordinary, especially Zhang Di's cultivation at this time, and he had experienced a lot of life and death battles, and there was a hidden majesty in his two eyes, which made Xiao Er shudder at a glance, how dare he ask for the silver given by Zhang Di, and hurriedly sent it back, and said: "Ah, the seniors want to inquire about the news, it is the blessing of the villain, how dare you ask for the silver of the seniors!"

Zhang Di snorted and took the silver, since he wanted to pretend to be a senior, he also had to pretend to be a similar, so he didn't refuse.

The little second swallowed his saliva, calmed down, and then said: "This senior doesn't know something, since the battle of the immortals and demons in Qingning City in the northern Wu Kingdom half a year ago, the situation has taken a sharp turn for the worse! Although my human cultivators have temporarily gained the upper hand and the Heavenly Demon army has retreated, how can the Heavenly Demon have suffered such a big loss, how can he give up? In the past six months, he has continuously sent small teams of Heavenly Demons to attack and harass us, destroying many of our villages......

The little two were articulate, and he said that it was a major event closely related to himself, so he naturally added fuel and vinegar, and said it vividly, Zhang Di kept asking questions in order to get enough information as much as possible, which led him to talk more, so he actually heard a lot of details in half an hour, and had a better understanding of the fairy and demon war.

In the end, the little two spread their hands and said, "...... Therefore, as soon as the five immortal sects of our Yue Kingdom saw that the situation was critical, they took the Qingyue faction as the leader, united the Wind and Fire Divine Sect, the Ten Thousand Demon Sect, the Spirit Beast Mountain and the Lingyue Sect to form the Northern Alliance, and wanted to go to the capital of Zhao State to have a miscellaneous competition with many sects in the south, first, to test the spirit valley, formation, alchemy and other techniques, and secondly, to exchange and exchange with each other, and prepare for the next bigger immortal and demon war. ”

As he spoke, he stretched out his hand and pointed at the disciples who were busy exchanging with each other, and said with envy: "That's why the disciples of these five great immortal sects will gather here, busy with each other, and prepare for the Zhao Guoda competition in half a year! I heard that as long as you achieve excellent results, you can get huge rewards, and maybe you can survive in the immortal and demon war!" (To be continued......
