After they had walked for several days, a green boundless grassland greeted Zhang Yan and Meng Yao, which was full of newly grown grass, stepping on which would give people a comfortable feeling.

The barren wasteland and the forest of trees with gray leaves had brought them with tedium and oppression, but now, all the downside emotions of them had been removed.

Such a good mood drove Meng Yao to shout out while running on the grassland, opening her hands to hug the soft breeze.

"Ah!" Zhang Yan copied her movements on the grassland, which made him extremely relax.

Suddenly he sensed that the Asura Change was launched by itself, and the golden dan in his Dantian was spinning wildly. Only after a while, he perceived that something in his body was about to crack at any time.

It was his bottleneck of breaking through to the next level, thus he sat on the grass with his legs crossed instantly, eliminating all the other thoughts in his mind.

The natural gas started to surge toward him like a gust of wind, making the grasses around sway.

Coming to the most crucial moment now, he closed his eyes tightly and concentrated himself on cultivating. With his cultivation growing in madness, he promoted to the fourth level of Martial Arts abruptly.

Though the breaking through had finished already, he didn't stop cultivating at once, and his golden dan was still working, which meant his cultivation was improving quickly still.

Meng Yao had already run to the distance. She called Zhang Yan several times, but didn't get any response. The strangeness drove her to turn back, but to her surprise, he was sitting on the grass ground motionlessly, as if in cultivation.

She immediately rushed to Zhang Yan to inspect him, and found his mind had entered a state without any distracting thoughts, which was the best state for warriors to develop cultivation.

Envy and jealousy suddenly climbed on her heart, because it was hard for the other warriors to enter such state, but seemed quite easy for Zhang Yan!

In the next second, she recalled the day when Zhang Yan had entered the state of combining himself together with the nature to depict the Vibration Figure. She suddenly wondered if there existed something that he couldn't do!

She stood beside him quickly, intending to protect him, after all, it was his most fragile time now.

"Have you forgotten where we are now?! This is the Huangquan Road, full of dangers! What if the ghosts come here now?! " She complained, "Fortunately, I am here with you! Or, you will definitely be eaten by the ghosts!"

All of a sudden, she perceived a kind of powerful breath in the distance was dashing toward them, which made her nervous instantly.

Sure enough, just after a little while, a creature with a pair of wings were flying to them rapidly, followed with a strong killing message, locking them two.

She took out the jade bamboo flute promptly, ready to start a fierce fight to protect Zhang Yan until he finished cultivating.
