Hei Tianyi found that both the Demon Dragon Clan and the Black Dragon Clan were from the Emperor Dragon bloodline, and both belonged to mutated races, but the Demon Dragon Clan had immunity to Bai Shui, while the Black Dragon Clan lacked this immunity.

In the past few hundred years, Hei Tianyi has been studying the Demon Dragon Clan, and he found that Bai Shui also has a certain poisonous effect on the Demon Dragon Clan, but it has never been able to cause fatal damage. Later, Hei Tianyi finally had some understanding, and found a substance against white water from the bloodline and bones of the Demon Dragon Clan, but he still needed to use the Demon Dragon Clan repeatedly to experiment before he could draw a conclusion.

Hei Tianyi has been making various attempts to save the Black Dragon Clan, and he has persevered. This spirit of selflessness moved Hei Yichen a lot.

After arranging everything, Sha Rui also followed the dark river channel opened up by Hei Yichen alone, and came to the barren area in the distance at the top of the black water. This time, with Hei Yichen answering, he didn't need to enter the top of the black water, he directly dived into the black water river and entered the top of the black water.

When old friends met, Sha Rui couldn't help but feel sad, he didn't expect Hei Tianyi and the two to come back to life, and he was at peace at the moment. However, he could also see that Hei Tianyi and Hei Ri had not completed their recovery. This kind of injury, especially Hei Tianyi, was covered with Dao scars all over his body, and it would take a long time to fully recover.

Sha Rui brought the news of the Sand Tomb War, the Lord of the Underworld had launched a war, but the Shaling Emperor did not wake up for a long time, fortunately, the Heishui River recovered, and the Shaling people returned to the domineering spirit of the same enemy, relying on the powerful formation of Shaling City, temporarily resisting the enemy's attack.

Heiri was anxious and said, "I'll go and help with my ancestor." Let Chen'er stay at the top of the black water for the time being. ”

Sha Rui hurriedly stopped and said, "No need. There are already quite a few Great Emperors there, and even the Heavenly Realm has pretended to send several Great Emperors to help, and there is no shortage of combat power. What is lacking is the peak combat power of Emperor Sha Ling to fight against the Lord of the Underworld. If you go, it will only expose your traces in advance, I personally suggest that you don't show your face, let Chen'er go to other continents by himself, at least they won't be too arrogant, afraid of Chen'er's combat power and dare not shoot casually. ”

The Lord of the Sand Tomb and the Nine Heavens Treasure Land are mortal enemies, if the Sand Spirit Clan is destroyed, the Lord of the Underworld may covet the Nine Heavens Treasure Land, which will threaten the safety of the Nine Heavens Treasure Land.

Therefore, the enemy of the enemy is not necessarily a friend, and the friend of the enemy is not necessarily the enemy.

"Afraid of Chen'er?"

Only then did Heiri remember that the prince he hadn't seen in twenty years had become famous.

Sha Rui smiled and said, "It seems that this kid is quite modest, and he didn't report your amazing achievements to your emperor? Brother Heiri, you have picked up a treasure! When your son was promoted to an immortal, there were twenty-seven thunder tribulations, and when he was promoted to an immortal, there were fifty-six thunder tribulations. There is no one before and no one after. ”

Twenty-seven thunder tribulations, ninety-nine to one tribulation, that is something that I have never heard of.

Hei Tianyi and Hei Ri were shocked, and looked at Hei Yichen repeatedly in disbelief, but they looked at Hei Yichen a little shy.

Sha Rui came this time to negotiate an alliance with the Black Dragon Clan.

The emperor of the Black Dragon Clan has reappeared in the world, and the next step must be to revitalize the race, and then revenge.

As allies, the Shaling clan was the first to come to congratulate, and at the same time, it was also a gesture of goodwill, and conveyed the wishes of the other clansmen slightly, and then sought a way to save themselves.

Before the Heavenly Emperor's thunderous wrath landed, they must make a covenant with the Black Dragon Clan to protect each other, attack and defend each other, and advance and retreat together. Prepare in advance so that you don't get beaten passively.

Black Sun is an emperor and an open-minded man, and he soon reaches a consensus with Sharui, and the two tribes make a pact of mutual assistance and reciprocity, and agree on a time to secretly sign a pact with other races.

The covenant is certain, which is equivalent to tying several ethnic groups together, and no one can escape, so they must go all out to help.

After reaching the covenant, Sha Rui was in a good mood and said, "Chen'er come with me to the Sand Tomb, Emperor Sha Ling will be resurrected, the Sand Tomb will be closed, and you can just return to the Protoss from there." ”

After consulting the opinions of the ancestor and the emperor, Hei Yichen agreed.

Hei Tianyi and Hei Sun both stayed, mainly to restore their cultivation, and more importantly, to secretly gather the clansmen back, regroup, and meet new challenges.

With the blades of the Star Fairy Flower Spirit, Hei Yichen followed behind Sha Rui and returned to the back mountain of Sha Ling Mountain in the Sand Tomb.

A small river in front of the back mountain is very lively, and many Shaling warriors soak their bodies in the river water to their heart's content, washing away the impurities contaminated in the world. The cleansed warriors of the Shaling clan rushed to the battlefield again with great vigor to meet the army of the Underworld.

"Brother, hey, you've been promoted again?"

Yue'er's eyes were sharp, and she shouted away from afar. Yue'er was no longer worried when she saw Hei Yichen at this time, she already knew from Renqing that her brother was still alive, and her mood was relaxed at the moment. At this time, there is still a kind of regret and reluctance to regain, but with her temperament, she will not show it.

Yue'er ran to Hei Yichen and looked him up and down, but found that Hei Yichen's cultivation had improved a little, and her big eyes were round, looking very surprised.

She watched him advance to the immortal with her own eyes, but she didn't expect that she hadn't seen him for just over a month, and his cultivation had reached the peak of the immortal again.

Sha Rui smiled: "What's so strange about this, your brother has returned to the ancestral land for the first time in his life, how can his cultivation not soar? He is already good, and he has tried his best to maintain this state, but I think he will soon be able to advance to a real person." ”

Before the appearance of the Tiantu, the Dragon Palace was the biggest treasure of the Black Dragon Clan, and the Hetu could only be ranked second. The aura in the Dragon Palace is so strong that the black water flowing around him is all made of aura. Coupled with the fact that the Dragon Palace, as the core of the ancestral land, has a lot of inheritance, Hei Yichen has benefited a lot in just a few days.

Originally, he was going to carry out the ancient blood immersion, but Hei Yichen forcibly resisted the endless temptation and agreed to calm the continent before going back to accept the ancient sacrifice. Now that his cultivation has been too fast, he doesn't want to soar too fast all at once, worrying about affecting his Daoji.

Hei Yichen took Yue'er's hand and said, "Now that the Heishui River has recovered, when I passed through the wall cave just now, I felt the bloodline breath of Emperor Shaling, and he should be able to return soon." Yue'er, my brother can't stay to help you, but you have to live, and after the war, my brother will be able to come and see you soon. If you want to be a brother, you can go to the top of the black water, and I will bring flowers to meet you there. ”

This is a war that belongs to the sand tomb itself, and outsiders cannot interfere. The most important thing is that he is not strong enough to participate in a war with the participation of the emperor and the emperor. If you insist on participating, it will only distract Yue'er from taking care of herself.

Yue'er nodded and said, "I have received a bloodline message from the emperor's father, and he can return today, so I am waiting for him here." Brother, put a hundred hearts, and as soon as the war here is over, I will go to the Xuanqian Continent to help you. ”

Hei Yichen solemnly handed a black medicine bottle into Yue'er's hand, and said in a low voice: "This is the pill liquid refined from the essence blood of our Black Dragon Clan, as long as there is still one breath left, if you drink it, you can come back to life." Thou hast remembered that thou shalt not be seen by a second man but thou and thy father. ”

This black essence blood pill liquid is extremely precious, it is extracted by the Open Heaven Holy Bead to absorb the essence blood of the Black Dragon Clan, one bottle can save two or three people, it is more effective than the life-saving Nine Pills, and the Black Dragon Clan generally does not give it to outsiders.

"This ...... It's too precious, and Yue'er must not accept it. ”

Of course Yue'er knew what this was, she retracted her hand and wanted to refuse, but was forced into her hand by Hei Yichen, so she carefully stuffed it into her arms with tears in her eyes.

Once killed, they immediately disperse into grains of sand, regrouped in the distance, and regained their ability to participate in the battle, and the Shaling tribe has the reputation of "the undead in battle".

"Boom!"

Hei Yichen was telling Yue'er, suddenly the sky and the earth cracked, the mountains shook, the ground cracked for a while, the ghosts cried and howled, and people were unstable on their feet, so they had to concentrate on resisting that terrifying impulse.

"Brother, the emperor's father has returned, take care!"

Yue'er held Hei Yichen's hand, with great reluctance, but there was a huge pull, pulling Hei Yichen, Yue'er grabbed Hei Yichen's hand tightly and refused to let go.

"Yue'er, you must be good!"

Hei Yichen felt that his voice had traveled through the ages and began to become illusory, and his body had become no longer real, and the fragments of the void around him were whistling by, he was worried about Yue'er's hand, shook off Yue'er's hand, and looked at this sister with a smile and reluctance, Hei Yichen's body slowly turned into a rain of light and disappeared into the ancient tomb.
