The tiger slowly approached Qi Yuancheng and stretched out his head towards him.

Qi Yuancheng was startled, and subconsciously wanted to release the red mist. But the tiger didn't attack, just gently grabbed the corner of his clothes, and pulled and motioned for Qi Yuancheng to go with it.

Only then did Qi Yuancheng understand that the tiger wanted him to follow. He put his mind at ease and simply followed the tiger towards the forest while testing his source field power.

With the addition of the letter stone, Qi Yuancheng's source field power that had just been depleted began to slowly recover. He was pleasantly surprised to find that the speed at which he unleashed the red mist had increased again, and the amount he released had also increased significantly. Qi Yuancheng was excited, it seemed that not only did the tiger have a huge harvest in the desperate battle just now, but even his source field power had been upgraded again. He casually released a large cloud of red mist, which instantly enveloped a large area around him. It was much faster than before leveling up, and he could feel that the number of creatures he could control at the same time had greatly increased.

Qi Yuancheng was about to continue to release the red mist, but the tiger turned his head to look at Qi Yuancheng and screamed with some dissatisfaction. Qi Yuancheng understood that the tiger was a little jealous of his red mist, and hurriedly dispersed the red mist embarrassedly. But he still couldn't suppress the joy in his heart, and quietly continued to test it in a very small area around his body.

It is also strange to say that Qi Yuan became uncomfortable when he was aware of the red mist by the tiger, and he had the idea of suppressing the concentration of the red mist in his heart. In this way, the red mist he released was almost invisible, but Qi Yuancheng knew that the effectiveness of this colorless mist was no worse than the dense red mist before, and the upgrade of his source field power even came with a change like fading color. And even better, he began to have a sense between him and the Gu Poison Mist, and he didn't need to rely on his eyes to stare at the Red Mist to sense the location of the Gu Poison as before.

"Great! This way, it will be more hidden when you face the enemy again! Qi Yuancheng's heart blossomed, in the past, in order to prevent the enemy from discovering his red mist, he often deliberately diluted the concentration and then sneaked into the enemy's side, and launched an attack by surprise. However, the problem with this operation is that after the concentration of red mist is reduced, the speed of successful control is often slower, and the evolution of colorless mist solves this problem, which can be said to be the best weapon for sneak attack.

Qi Yuancheng had itchy hands, and he couldn't wait to try his new source field power. He stopped and said to the tiger, "Boss Tiger, you wait for me first." As he spoke, he looked excitedly into the woods, intending to find a small animal to practice his skills. Seeing that the tiger was a little reluctant, Qi Yuancheng said to it again: "Don't worry, don't worry, I won't experiment with you, and I won't hurt other animals, just try." ”

At this moment, a squirrel crossed through the trees. Qi Yuancheng spent these days in the jungle, his vision and sense became sharp, and he quickly locked on the squirrel's movements. In order to test the concentration of Gu poison that he could compress, he manipulated a highly condensed Gu poison mist to float towards the squirrel, and due to its high density, the mist took on a faint green color.

However, this experiment did not allow Qi Yuancheng to manipulate Gu poison to invade the body of the creature silently, the mist had just touched the squirrel's fur, and the squirrel jumped up screaming as if it had been attacked by something, and then fell to the ground.

Qi Yuancheng was shocked, his Gu poison was originally odorless and tasteless, and after this upgrade, it didn't even have the original rich red color. But why did the squirrel seem to be aware of it? He saw that the squirrel had fallen to the ground and was motionless, so he hurriedly ran over to check.

Qi Yuancheng was even more surprised when he saw the squirrel that fell to the ground. The squirrel's original yellow-brown fur was as if it had been burned by fire, and it was blackened.

The squirrel twisted its body in pain on the ground, and soon became stiff, several wounds under its charred fur that even oozing bright red liquid.

Qi Yuancheng leaned down to examine the squirrel's wound, but he was so shocked that he couldn't speak. These deep wounds were exactly the same as those caused by the locusts that had just fought with them!

"Are there any bugs around?" Qi Yuancheng was a little incredulous. "Hey! Tiger Boss! Stop! He called out to the tiger, then released a colorless mist and made a vigilant round.

The tiger also leaned down slightly to look around, and slowly moved closer to Qi Yuancheng.

But after a while, Qi Yuancheng didn't find any signs of flying insects. He wondered a little, thinking that these bugs couldn't kill the squirrels in front of him and not show up.

"Could it be my Gu Poison Mist?" Qi Yuancheng thought of a possibility that even he couldn't believe. He suppressed the surprise in his heart and tried again.

Qi Yuancheng recalled the operation he had just made, and concocted a high-concentration mist in the same way. The tiger stared at him in bewilderment, and suddenly took two steps back in some fear and roared at him.

Qi Yuancheng sensed the fog in front of him, and estimated that the concentration had reached the limit of what he could condense, so he slowly controlled the pale green mist the size of a pigeon's egg to float towards the trees in front of him.

"Sting!" The moment the mist came into contact with the trunk of the tree, there was a violent reaction, and the bark of the tree scorched and withered at a visible speed, which was exactly the same effect as the green acid sprayed by the locust swarm before!

Seeing this, the tiger began to yell at Qi Yuancheng with hostility.

Qi Yuancheng was also so frightened that he took two steps back, he didn't care about appeasing the tiger, he just stared at the charred trunk in a daze.

"Could it be that my source field power has actually changed?" Qi Yuancheng couldn't believe the scene in front of him. His idea at the moment was to immediately contact Hua Banxue, who was thousands of miles away, and ask what was going on in this situation.

After a long while, Qi Yuancheng recovered from the shock. He muttered to the vigilant tiger on the side, "Tiger boss, don't panic. I'm probably getting better like you. ”

After calming the tiger's emotions, Qi Yuancheng began to experiment again. He hid among the trees farther away from the tiger and tried to erode the trees with different concentrations of mist, and the result was just as he expected, when the poisonous mist reached a certain concentration, it could produce the effect of locust swarm acid.

"This trick is powerful, but it's too hard to launch it once, so you still have to use it with caution." Qi Yuancheng launched the "acid mist" two or three times in a row, and he was extremely tired, similar to the feeling of detachment when he fought the insect swarm before.

Qi Yuancheng returned to the tiger's side, took out the letter stone, sat on a large stone and slowly recovered. He looked at the letter stone in his hand, and his heart was a little excited.

"This letter stone is stronger than the few we have found in the past, not to mention the strong source field power stimulated, and even the promotion enhancement has an amplification effect." Qi Yuancheng thought back to the strong source field power and potential displayed by the black bears, tigers, and locust swarms he had seen in the past two days, and judged that this letter stone was the high-grade letter stone mentioned by Hua Banxue.

Thinking of this, Qi Yuancheng stopped drawing energy from the letter stone and carefully put the letter stone back into his pocket. He was going to conserve the energy of the letter stone in case he needed it.

At this time, the tiger roared again, as if prompting Qi Yuancheng to hurry up and follow it.
