Looking at the array cards that changed from black to white in front of him, Tang Lang held the mentality of trying it out, and tried to communicate with the array cards again with blood refining and divine refining.

Several red blood beads flew from Tang Lang's fingers to the white jade array card, unlike the previous contact with the black array card, as soon as the blood beads fell on the array card, they were immediately absorbed by the formation card, and caused a ripple of light on the surface of the array card.

"There is a door!" Seeing this change, Tang Lang was overjoyed in his heart, and quickly forced out more essence blood from his fingers to integrate into the array card, and finally after absorbing the amount of essence blood in the sea bowl, the entire array card seemed to be soaked in blood, exuding vitality.

After releasing a large amount of essence blood, Tang Lang felt dizzy for a while, but he was still overjoyed to see the formation card change again, and couldn't help but get closer to check, his hands unconsciously touched both sides of the formation card, and was immediately firmly absorbed on it, accompanied by the spiritual power in his body being sucked into the formation card like a tide.

"I'll go, are you going to suck me into a human being!" Tang Lang couldn't control the flow of spiritual power at all, and in the blink of an eye, the ten spirit vortices in his mind and the dantian were exhausted at the same time, and if this continued, even the spirit vortex would be annihilated.

Tang Lang remembered the energy stored in the system before, and said in a panic: "System, hurry up and hand over the energy, otherwise I'm going to be finished!"

In the past, it took a lot of effort to ask for energy from the system, but this time the system didn't say a word, and continuously injected the more than 20,000 points of energy stored before into Tang Lang's body through the tattoo on his chest, and then converted it into spiritual power and transported it into the array card.

"Huh......" Tang Lang finally breathed a sigh of relief, and focused all his attention on the refining of the array cards: "Such a small array card can actually absorb such a large amount of spiritual power, I want to see how big your belly is!"

It was not until the energy of the system was consumed that there were only more than 3,000 points left, that the speed at which the array card absorbed spiritual power slowly decreased, and then the glow was great, and after several light and extinction, it shrank into a palm-sized pocket array card and fell into Tang Lang's hand.

"This ...... Even if it succeeds?" Tang Lang held the pocket array card in front of him, and looked carefully, what terrain on the previous array card was displayed, and the light point markers all disappeared, more like a mere jade plate than a formation card.

Tang Lang infiltrated his mind into the array card, and with a "boom", the perspective changed dramatically, he seemed to have entered the array card, condescendingly overlooking the entire Dragon Pool Secret Realm from the sky, he randomly locked his eyes on one of the red light spots, and the scene in front of him was quickly magnified until it was suspended above the light points.

"Isn't this one of the players who came in together!" Tang Lang was secretly surprised in his heart, tried and tested many times, and finally found Zhuang Tianrui's location from many points of light.

At the same time as he looked at the other party, Zhuang Tianrui also looked up at the sky with a slight hesitation: "How can you feel like being spied on? Could it be that someone has been monitoring this secret realm? Why did it disappear again, it was actually an illusion?"

Tang Lang hurriedly withdrew his mind into his body, with this array card, there was no suspense about the return journey, and all that remained was how to pass through that transparent light mask.

Walking to the location of the light mask in his memory, Tang Lang reached out and touched it, and the light mask had actually disappeared!

"It's probably because of refining the array cards!" Tang Lang stopped thinking about it and hurried to continue on his way.

With the array card as a guide, he obtained all the spiritual springs along the way, not only raising his cultivation to the eighth grade of the division level, but even replenishing the consumed system energy to more than 30,000 points again.

Originally, he wanted to break through to the sect level in one fell swoop, but after he promoted his cultivation to the eighth grade of the division level, he had a feeling of impetuousness when he wanted to forcibly improve, so he had to stop.

Calculating the time, he has been in the secret realm for more than five days, so he should find Zhuang Tianrui first, so that he can have a suitable reason to return to Tianlan, so as to conceal the matter of the refining array card.

"Wait!" the system reminded again.

"What's going on around?" Tang Lang was taken aback, thinking that he had encountered some powerful soul beast.

"Master, the system energy is sufficient again, it is recommended to start upgrading immediately, this upgrade will bring a new function, which will be of great help to the owner!"

"Oh, let's hear it!" Since the fifth upgrade of the system requires fifteen thousand points of energy, Tang Lang never thought that it could be achieved so quickly, so he never took it to heart, and now listening to the system take the initiative to talk about it, he suddenly became interested.

"After this upgrade, the master can give birth to a phantom stand-in, which is very useful, and can replace the master's cultivation, perception skills, and even exploration ......"

"This is equivalent to a plug-in!" Tang Lang was a little eager to try, but the consistent style of the system made him very cautious.

"To be clear, how long will this upgrade take, what are the conditions for creating a stand-in, and what are the restrictions on using it?"

The system paused and began to explain: "The system upgrade will take about five hours, so it won't take too long. It takes 10,000 points of energy to spawn a stand-in, and it also needs the master to inject a lot of ideas to make it self-conscious, so that it can accept the control of the master, and the stand-in can survive alone, without any restrictions, but as long as the master summons, he can immediately enter the system space, and at the same time synchronize his cultivation and perception with the master!"

"In this way, then I can't ......" A bold idea arose in Tang Lang's heart: "The spiritual power in this secret realm is very sufficient, if I place a stand-in here and let him concentrate on cultivation here, when I recall it, his cultivation will definitely skyrocket a lot!"

"Upgrade, upgrade immediately, this opportunity must not be missed!" Tang Lang immediately ordered the system to upgrade to maximize the opportunities in the secret realm.

As the upgrade began, the system fell silent, and the scanning function was also turned off, Tang Lang could only move forward carefully according to the prompts of the array cards to avoid encountering any powerful soul beasts, and the speed dropped by more than half compared to before.

After five hours, a long-lost prompt finally came from his mind: "Ding!

Tang Lang had already found a spiritual spring according to the prompts of the array card at this moment, and waited for a long time, when he heard that the system had completed the upgrade, he couldn't wait to go in and check.

There was no major change in the space and light curtain, and he didn't have the heart to check it carefully, so he kept urging: "Stand-in, I want a stand-in!"

The system projected a light cluster on the light curtain, reminding the precautions again: "Master, it is about to start giving birth to a phantom stand-in, at present, the system reserves energy remaining 15,360, the energy is sufficient, please project the mind on the light cluster, increase the output of the idea, and must not be interrupted during the period, otherwise the stand-in condensation will fail!"

Tang Lang wrote down a few things one by one, and confirmed that there were no soul beasts around him on the formation card, and then he made up his mind: "Begin!"

He projected all his thoughts on the light cluster, and the system also continued to inject energy, and the light cluster began to churn and expand, gradually appearing in the rudiments of limbs, followed by the head, and the height was also constantly elongated, and the last silver figure appeared beside Tang Lang.

"You...... Do you call this kind of thing a phantom stand-in?" Tang Lang looked at the figure in front of him, and suddenly felt deceived.

The stand-in in his mind should be exactly the same as himself, he can imitate his movements and even his voice, and do many things on his behalf, but the current silver figure is just a basic humanoid outline, and even his facial features are blurred, and letting it out will only scare people to death.

"Yes, the master is the stand-in, but it is still in the most basic stage, and it needs to be continuously invested in energy to upgrade, and finally it can meet the requirements of the master!" As soon as the system voice fell, the details of the stand-in upgrade were displayed on the light curtain, and the first three upgrades only needed 10,000 points of energy, and then gradually increased, and finally reached the top ten levels, and 200,000 points of energy were needed.

Tang Lang was already a little dizzy just by seeing the energy demand on the rows of light curtains, and he almost wanted to cry without tears: "I knew you were a pit goods, but I didn't expect you to make another pit goods to pit me! 200,000 energy, why don't you grab it?"

The system replied vigorously: "According to the content on the formation card just now, as long as you put the stand-in here to absorb the spiritual spring, you will definitely be able to rise to the full level!"

Tang Lang was so angry that he trembled: "You are not only a cheat, but also a fool!" The secret realm of Hualong Pool is strictly controlled by Tianlan, it is okay for me to secretly take a small advantage, if I absorb all the spiritual springs here, God knows what kind of chaos will be caused, do you want to kill me?"

Tang Lang's head was furious, but it was impossible for the energy that had been consumed to be turned back, so he would not pursue this problem for the time being, and instead tried to control the stand-in. Because of the large number of ideas integrated into himself, the stand-in did not deviate from the execution of his instructions.

"It's half the battle!" Tang Lang ordered the stand-in to enter the spirit vortex on the side and begin his first practice.

According to the method taught by Tang Lang, the spiritual power was inhaled into the body, and the cultivation of the stand-in began to rise rapidly, and the spiritual vortex was produced one after another, and in the blink of an eye, the kung fu had broken through the apprentice, the scholar, and the scholar level, and steadily entered the master-level realm.

"Stop first, polish your state of mind before making a breakthrough!" Tang Lang stopped the practice of the stand-in, and instead let it sink to the bottom of the spiritual spring, stay in the secret realm, and devote himself to the perception of everything in the outside world.

"You can sense his state, right?" Tang Lang was a little uneasy, and asked the system repeatedly.

The system also took the trouble to reply: "Don't worry, master." Any changes in the stand-in will be fed back to me, whether it is the improvement of cultivation or the change of mood, I will remind you in time, waiting for you to make the next instructions. ”

"None of this is important, the most important thing is to hide yourself, even if we all go out of the secret realm, the Tianlan royal family may have some secret method to monitor the wind and grass in the secret realm, don't be careless!"

Tang Lang glanced back at the Lingquan where the stand-in was, and strode towards Zhuang Tianrui's location.
