Su Yu heard the words clearly, knew the value of the flyover flower, and knew the reason why so many six products were vying for a flyover flower.

If the six-rank source martial artist wants to break through to the seventh-rank, he can only open the bridge between heaven and earth.

If you can't open the bridge between heaven and earth, you may only be able to stay in the realm of six products for the rest of your life.

It is very difficult to open the bridge between heaven and earth, so the source medicine and source pill that can increase the probability of success such as Tianqiao Flower and Tianqiao Pill are naturally relatively precious.

Of course, because source medicines such as Tianqiaohua are not rare, the price is not outrageously expensive.

While talking, the group came to the foot of the Great Wall and was discovered by the defenders of the city.

......

"What are you talking about? Su Yu is back? Is this true?" a voice asked continuously, although the tone was calm, but three consecutive questions expressed that the owner of the voice was actually not calm in his heart.

"Yes, Instructor Tang, the soldiers guarding the city have confirmed that it is indeed Su Yu who came back, this child is really blessed and has a great life, and he has come back safely!" Bai Xue said, her tone was a little embarrassed, she thought that Su Yu, who had been missing for six days, could not live, but at this moment she came back intact.

Of course, when she sighed, she was also a little excited, Su Yu was able to come back safely, she was also happy, although she didn't like Su Yu's soldiers, but it was enough for her soldiers to come back alive to make him happy.

"That's great, let's go, go see this rabbit cub, I want to know how he has been living outside for the past six days. Tang Xiong got up and walked out of the room.

Su Yu returned, and there was no cause for any turmoil, but he still couldn't hide it from someone with a heart.

In a dimly lit room, a figure hidden in a dim corner was slightly stunned after receiving the news: "Su Yu actually came back alive? What a waste, after making so many preparations, Wupin can't kill a Sanpin? The killer of tissue culture is really getting weaker and weaker!"

Pass the order, always pay attention to Su Yu's movements, and if there is a chance to assassinate again, until Su Yu dies!

You don't need me to teach them how to do it!?"

"Yes, my lord's order, my subordinates will definitely bring it. Another voice rang out in the room, and then a dark shadow flashed away.

......

Tang Xiong took a big stride, and soon found Su Yu with Bai Xue, at this moment Su Yu had just finished the interrogation and confirmed that Su Yu was not a fake, the moment he saw Su Yu, Tang Xiong couldn't help but breathe a sigh of relief, as if he had put down something heavy.

When he came to Su Yu's side, he stretched out his big hand like a fan and patted Su Yu's shoulder twice and said: "Good boy, I really think you can't come back, just come back, it just so happens that your support mission will end tomorrow, and you will return to the mainland tomorrow."

Tell me how you've been living outside these days. ”

Su Yu grinned when he was patted, and said: "I have seen Tang Jiaoguan and Instructor Bai, I can come back alive outside because I have met nobles, and if I don't have the help of Wang Gongzi and others, I really may not be able to come back alive." ”

Su Yu didn't tell the truth, but such a set of rhetoric.

Su Yu didn't trust the people in the Great Wall, even if it was Tang Xiong, this was not to blame Su Yu, the person who wanted his life was in the city, before he was sure who it was, anyone was suspicious, Tang Xiong and others were also the object of Su Yu's suspicion.

Of course, this set of rhetoric was not made up by Su Yu temporarily, he had already colluded with Wang Feng before this, and the price was a favor.

So when Su Yu's voice fell, Wang Feng said: "Just in time, I came back with Su Gongzi, it's just a trivial matter, you don't have to take it to heart." ”

"Thank you!" Tang Xiong said to Wang Feng and the others, looking at the seven six-rank peak source martial artists beside Wang Feng, he was shocked that Wang Feng's lineup was luxurious, and at the same time, he also understood the reason why Su Yu was able to come back safely.

Under the protection of the seven six-rank peak source martial artists, if they can't come back alive, then Gao Pin can survive outside the Great Wall.

Although it is dangerous beyond the Great Wall, it is not too dangerous, unless it is a dead alien city.

"You're welcome, I still have something to deal with, so I'll leave first, and I'll see you when you have a fate!" Wang Feng arched his hand and left here with seven maids.

Tang Xiong and the others did not stay, because they were not mothers-in-law, after seeing the figure of Wang Feng and the others, Tang Xiong continued to say to Su Yu: "Go, go back and repair it, and we will leave in twelve mornings." ”

After that, he turned around and left, although he cared about Su Yu very much, but he didn't show it, he still looked like a cold big bear.

Su Yu hurriedly followed and returned to the barracks with Tang Xiong.

Needless to say, the recruits were surprised to see Su Yu come back.

Except for a few words with Yan Tianxing, Su Yu didn't bother with anyone else after returning to the barracks to make corrections.

Instead, he quickly found a quiet place to begin the 'retreat' upgrade.

A seven-grade source energy stone plus the essence points that have been extracted from the air in the past few days, as well as some other harvests, Su Yu has already saved a large amount of essence points, enough for upgrades, Su Yu checked his current essence points, and his body couldn't help but tremble slightly, the essence points have reached eight figures: 12,250,000 points!

Without hesitation, Su Yu just began to burn the essence and improve his cultivation, and his life outside the Great Wall in the past few days completely made Su Yu understand that he was still very weak.

......

Burning 3 million essence points, Su Yu's cultivation realm was raised to the immortal silver tendon.

Burning 5 million essence points, Su Yu's cultivation realm was raised to the immortal golden tendon.

A few hours later, Su Yu completed the upgrade, and after filling up the immortal god, there were still 4,200,000 essence points left.

The remaining essence points could not be further upgraded, but Su Yu did not skimp this time, and burned 2 million essence points again, raising the extraction skill and the spirit eye skill by one level again.

There were still 2.2 million essence points left, so Su Yu didn't continue to consume them, and stayed them as a presence.
